在異種網路間之遞交中重設網路通訊位址之方法Method for resetting network communication address in delivery between heterogeneous networks

本發明概有關於異質(heterogeneous)網路間之遞交作業，且特別是有關於一種在異質網路間之遞交作業中重設一IP位址的方法。本發明雖適合於一廣泛應用範圍，然此者特別適用於讓一行動用戶站台能夠有效率地於異質網路之間進行遞交。The present invention relates generally to the delivery of heterogeneous networks, and more particularly to a method of resetting an IP address in a delivery operation between heterogeneous networks. Although the present invention is suitable for a wide range of applications, it is particularly suitable for enabling a mobile subscriber station to efficiently deliver between heterogeneous networks.

一般說來，為異質網路間媒體獨立遞交作業之「國際標準化」而進行中的IEEE802.21之目標，即為藉由在異質網路之間提供無縫隙(seamless)遞交及服務連續性，以增強對於行動用戶站台的使用者便利性。其基本要求經定義為一HIM功能、一事件觸發器、一命令服務及一資訊服務(IS)。In general, the goal of IEEE802.21, which is the "international standardization" for the independent submission of media between heterogeneous networks, is to provide seamless delivery and service continuity between heterogeneous networks. To enhance user convenience for mobile user stations. The basic requirements are defined as an HIM function, an event trigger, a command service, and an information service (IS).

一行動用戶站台(MSS)係一支援至少兩種介面型態的多重模式節點。在此，該介面可為例如一像是802.3基礎式乙太網路之有線線路型式介面；一基於像是IEEE802.11、IEEE802.15、IEEE802.16等等之IEEE802.XX的無線介面型式；一由像是3GPP及3GPP2等等之胞狀(cellular)標準化組織所定義的介面型式。A mobile subscriber station (MSS) is a multimode node that supports at least two interface types. Here, the interface may be, for example, a wired line type interface such as 802.3 basic Ethernet; a wireless interface type based on IEEE 802.XX such as IEEE 802.11, IEEE 802.15, IEEE 802.16, etc.; An interface type defined by a cellular standardization organization such as 3GPP and 3GPP2.

第1圖係一多重模式行動用戶站台之協定堆疊架構圖。Figure 1 is a diagram of a stacking architecture of a multi-mode mobile subscriber station.

現參照第1圖，一多重模式行動用戶站台在每一模式皆具有一實體層，以及每一模式接有一媒體接取控制層。並且一MIH層臥置於一IP層之下。Referring now to Figure 1, a multi-mode mobile subscriber station has a physical layer in each mode and a media access control layer in each mode. And a MIH layer is placed under an IP layer.

「媒體獨立遞交(MIH)」應經定義於各IEEE802系列介面間，或是在像是上述由即如3GPP及3GPP2之胞狀標準化組織所定義的非802系列介面之各802系列介面間。此外，對於該無縫隙遞交服務，應能夠支援一像是「行動IP」及SIP(會期啟動協定)的上層行動支援協定。"Media Independent Submission (MIH)" shall be defined between the various IEEE 802 series interfaces or between the 802 series interfaces such as the non-802 series interfaces defined by the Cell Standardization Organizations such as 3GPP and 3GPP2. In addition, for the seamless delivery service, it should be able to support an upper-level operational support agreement such as "action IP" and SIP (session initiation agreement).

底下將解釋「行動IPv4」。The "Action IPv4" will be explained below.

一支援一行動IP之網路的組態包含一本家代理器、一外部代理器(foreign agent)及一行動用戶站台。The configuration of a network supporting a mobile IP includes a home agent, a foreign agent, and an action user station.

而對於行動IP的運作，要求下列各項功能。For the operation of mobile IP, the following functions are required.

1)代理器探索(Agent Discovery)代理器探索是一種決定一行動用戶站台目前究係經連接至其本家網路或現位在一外部網路處的方法。藉此方法，該行動用戶站台可偵測出該者既已移入至另一網路內。1) Agent Discovery Agent Discovery is a method of determining whether a mobile subscriber station is currently connected to its home network or is located at an external network. In this way, the mobile subscriber station can detect that the subscriber has moved into another network.

2)註冊一註冊功能可提供一種在一行動用戶站台偵測到其遷移至另一網路內的情況下，依照將目前位置資訊遞交至一本家代理器之方式，使得一在一本家網路上提供之服務能夠在一新網路上提供的彈性機制。2) The registration-registration function can provide a way to submit the current location information to a home agent in a way that the mobile station station detects its migration to another network, so that it is on a home network. The service provided provides a flexible mechanism on a new network.

3)路由處理若一行動用戶站台經鏈結於一外部網路，即需要一種路由傳送功能以往返於該行動用戶站台適當地路由傳送資料包。3) Routing Processing If an mobile subscriber station is linked to an external network, a routing function is required to properly route the data packets to and from the mobile subscriber station.

4)轉交位址(CoA)若一行動節點既已移離到另一子網路，則一行動IP提供兩種方法，即「外部代理器(FA)」－CoA以及共置CoA，為以建立轉交位址。4) Transfer Site (CoA) If an action node has moved away from another subnet, then an action IP provides two methods, namely "external agent (FA)" - CoA and co-located CoA. Establish a referral address.

FA－CoA是由一外部代理器透過一代理器公告(advertises)訊息所提供，其中該外部代理器的IP位址被用來作為一轉交位址。在共置CoA裡，是透過一位於一外部網路處之「動態主機組態協定(DHCP)」伺服器，將一轉交位址指配予一行動節點。The FA-CoA is provided by an external agent through an agent advertised message, wherein the external agent's IP address is used as a care-of address. In a co-located CoA, a handover address is assigned to a mobile node via a Dynamic Host Configuration Protocol (DHCP) server located at an external network.

底下將解釋「行動IPv6」。The "Action IPv6" will be explained below.

行動IPv6比起行動IPv4更能有效率地支援行動性，並且具有比起該行動IPv4更好的可延展性。底下將解釋行動IPv6的各項基本構件及功能。Mobile IPv6 is more effective in supporting mobility than Mobile IPv4 and has better scalability than IPv4. The basic components and functions of Mobile IPv6 will be explained below.

1)行動節點(MN)：改變其網路接取的主機或路由器。1) Mobile Node (MN): Change the host or router that its network accesses.

2)對應節點(CN)：與一行動用戶站台進行通訊的主機或路由器。2) Corresponding node (CN): A host or router that communicates with a mobile subscriber station.

3)主機代理器(HA)：一路由器，此者在一本家網路內之各路由器間具有一行動用戶站台之註冊資訊，藉以將資料包發送至在一外部網路上之行動用戶站台的目前位置。3) Host Agent (HA): A router that has registration information for a mobile subscriber station between routers in a home network to send the data packet to the current mobile subscriber station on an external network. position.

4)轉交位址(CoA)：「網際網路協定(IP)」位址，此者經連接至一既已移離至一外部網路內之行動用戶站台。4) Transfer Address (CoA): An "Internet Protocol (IP)" address that is connected to an active subscriber station that has been removed from an external network.

5)綁接(Binding)：將一由一行動用戶站台向一本家代理器所註冊之CoA，與一相對應之行動用戶站台的本家位址兩者一起相比較。5) Binding: A CoA registered by a mobile subscriber station to a home agent is compared with a home address of a corresponding mobile subscriber station.

6)綁接更新(BU)：由一行動用戶站台用以知會HA及其CoA的各CN。6) Binding Update (BU): Each CN used by an mobile subscriber station to inform the HA and its CoA.

7)綁接確知(BACK)：對於BU的回應訊息。7) Binding Confirmation (BACK): A response message to the BU.

8)綁接請求(BR)：若一相對應行動用戶站台無法在一行動用戶站台之綁接資訊的計時器逾期之前接收到該BU，則用以請求BU之訊息。8) Binding Request (BR): If a corresponding mobile subscriber station cannot receive the BU before the timer of the binding information of the mobile subscriber station is overdue, the message for requesting the BU is used.

9)CoA取得：在行動用戶站台移離下，利用鄰者探索與位址自動組態功能，以自動地組態位置資訊。9) CoA acquisition: Using the neighbor discovery and address automatic configuration function to automatically configure the location information under the mobile user station removal.

10)路由器最佳化：在既已儲存綁接資訊之後，相對應的行動用戶站台即可直接地與一行動節點進行通訊，而無須一本家代理器。10) Router optimization: After the binding information has been stored, the corresponding mobile user station can directly communicate with a mobile node without a home agent.

11)位址自動組態IP位址自動建立被歸類於一狀態保留型式之位址自動組態，以利用此一伺服器作為DHCP而取得一位址，以及一非狀態位址自動組態，以由一主機側而建立其本身的位址。在利用該伺服器的方法裡，若一主機側向一DHCP伺服器請求一位址，則由該DHCP伺服器將各可用位址之其一者配置給該主機側。在該非狀態型式位址自動組態裡，按照將其介面IP資訊以及獲自於一路由器之字首資訊或是已知的字首資訊綁接合一之方式來建立一位址。11) Automatically configuring the IP address of the address to automatically establish an address automatic configuration that is classified into a state reserved type, to obtain an address by using the server as a DHCP, and automatically configure a non-status address. To establish its own address by a host side. In the method of using the server, if a host side requests a single address from a DHCP server, the DHCP server configures one of the available addresses to the host side. In the automatic configuration of the non-state type address, the address is established by binding the interface IP information and the prefix information obtained from a router or the known prefix information.

底下將解釋FMIPv6(行動IPv6的快速遞交)。FMIPv6 (Fast Delivery of Mobile IPv6) will be explained below.

首先，FMIPv6係一為以藉由根據在第2層內的遞交估計資訊以令快速地進行移動偵測及NCoA(新轉交位址)取得，俾降低第3層內之整體遞交延遲的協定。底下說明將解釋該FMIPv6運作的各項基本構件及訊息。First, FMIPv6 is a protocol for reducing the overall delivery delay in Layer 3 by making motion detection and NCoA (new handover address) acquisition based on the delivery estimation information in Layer 2. The following description will explain the basic components and messages of the FMIPv6 operation.

1)PAR(先前接取路由器)：在進行一行動節點遞交之前的內定路由器。1) PAR (previously accessed router): A default router before a mobile node is submitted.

2)NAR(新接取路由器)：在進行一行動節點遞交時所估算的內定路由器。2) NAR (New Access Router): The default router that is estimated when a mobile node is submitted.

3)PCoA(先前轉交位址)：在一PAR子網路內之行動節點的有效CoA。3) PCoA (previously transferred address): The effective CoA of the mobile node within a PAR subnet.

4)NCoA(新轉交位址)：在一NAR子網路內之行動節點的有效CoA。4) NCoA (New Care-of Address): The effective CoA of the mobile node within an NAR subnet.

5)RtSolPr(對於代理器的路由器懇請)：自一行動節點，透過一經發送至PAR之訊息，提出一對於潛在遞交之資訊的請求。5) RtSolPr (for routers of the agent): From a mobile node, a request for potentially submitted information is sent through a message sent to the PAR.

6)PrRtAdv(代理器路由器公告)：自PAR透過一經發送至一行動節點之訊息以提供對於一鄰近鏈結的資訊，並且運作如一對於一網路啟動遞交的觸發器。6) PrRtAdv (Proxy Router Advertisement): A message sent from a PAR to a mobile node to provide information about a neighboring link and operates as a trigger for a network initiated delivery.

7)FBU(快速綁接更新)：一行動節點請求一PAR以將其流量接收處所改變至NAR內的訊息。7) FBU (Fast Binding Update): A mobile node requests a PAR to change its traffic reception location to a message within the NAR.

8)FBACK(快速綁接確知)：對自PAR所產生之FBU的回應訊息。8) FBACK (Fast Binding Confirmation): A response message to the FBU generated from the PAR.

9)HI(遞交啟動)：從PAR發送至NAR以表示一行動節點之遞交的訊息。9) HI (Submission Start): A message sent from the PAR to the NAR to indicate the delivery of a mobile node.

10)HACK(遞交確知)：回應於HI而從NAR發送至PAR之訊息。10) HACK (Submission Confirmation): A message sent from NAR to PAR in response to HI.

11)FNA(快速鄰者公告)：從一行動節點發送至NAR，藉以表示該行動節點確認使用NCoA，並且在尚無法接收到FBACK情況下接取一新網路的訊息。11) FNA (Fast Neighbor Announcement): sent from a mobile node to the NAR, indicating that the mobile node confirms the use of NCoA and receives a new network message if FBACK cannot be received yet.

MIH功能被放置在一IP層之下，並且可利用一觸發器事件與一來自像是其他網路等等之資訊的第二層(Layer 2)輸入值，藉以利於進行遞交處置處理。該MIH功能可包含各種基於可對一遞交處理程序產生影響之使用者政策及組態的輸入值，並且在該MIH與一像是「行動IP」及SIP的第三層(Layer 3)項目之間定義一般介面。這些介面提供關於一第一層(Layer 1)(實體層)、該第二層(Layer 2)(MAC層)以及行動管理的資訊，並且該MIH可藉助於該事件及資訊服務，取得有關於較低層與網路的資訊。The MIH function is placed under an IP layer and can utilize a trigger event and a Layer 2 input value from information such as other networks to facilitate the delivery process. The MIH function can include various input values based on user policies and configurations that can affect a delivery handler, and in the MIH and the third layer (Layer 3) project like "Action IP" and SIP. Define a general interface. These interfaces provide information about a Layer 1 (physical layer), a Layer 2 (MAC layer), and action management, and the MIH can be obtained by means of the event and information service. Lower level and network information.

一較高管理項目被放置在一上層處，以監視並控制在一行動用戶站台內之各種鏈結的狀態，並且扮演一遞交控制功能及一裝置管理器功能的角色。在此情況下，可獨立地且個別地放置定位該遞交控制功能及該裝置管理器功能。或另者，可將兩者功能納入合一以作為一較高管理項目。A higher management project is placed at an upper level to monitor and control the status of the various links within a mobile subscriber station and to act as a delivery control function and a device manager function. In this case, the delivery control function and the device manager function can be positioned independently and individually. Alternatively, the two functions can be combined into one as a higher management project.

第2圖為一各功能項目，以及一行動用戶站台與具各MIH功能之網路的傳送協定圖式，其中虛線表示各原生項目、事件觸發器等等。Figure 2 is a functional project, and a transport agreement diagram of a mobile subscriber station and a network with MIH functions, wherein the dotted lines indicate respective native projects, event triggers, and the like.

對於快速遞交，一網路層需要使用來自於一鏈結層的資訊，藉以儘快地重建一連線。一鏈結層事件有助於估算一使用者的移動情況，並可協助一行動用戶站台及網路事先準備遞交作業。For fast delivery, a network layer needs to use information from a link layer to rebuild a connection as quickly as possible. A link event helps to estimate the movement of a user and assists a mobile subscriber station and the network in preparing for delivery.

一為以遞交之觸發器可開始於一實體層(PHY)及一媒體接取控制層(MAC)。此觸發器之起源可為一本地堆疊或一遠端堆疊。第3圖為一觸發器模型圖式。A trigger for delivery can begin with a physical layer (PHY) and a media access control layer (MAC). The origin of this trigger can be a local stack or a remote stack. Figure 3 is a trigger model diagram.

一事件觸發器提供目前信號之狀態、另一網路之狀態變化以及一估算變化，並且提供在一實體層與一媒體接取控制層之間的變化，和一特定網路的屬性變化。An event trigger provides a state of the current signal, a state change of another network, and an estimated change, and provides a change between a physical layer and a media access control layer, and a property change of a particular network.

可將事件型態分類成PHY層事件、MAC層事件、「管理」事件、L3事件、「應用程式」事件等等。Event types can be classified into PHY layer events, MAC layer events, "management" events, L3 events, "application" events, and the like.

底下解釋一基本觸發器事件。Explain a basic trigger event below.

首先，「Link_Up」出現於在一特定鏈結介面上建立一第2層連接的情況下，以及在可從一上層處傳送L3封包的情況下。在此情況下，將決定組態該鏈結之所有L2組態皆為完成。並且，事件來源為「本地MAC」及「遠端MAC」。「Link_Up」的各項參數可如表1中所示。First, "Link_Up" appears in the case where a Layer 2 connection is established on a particular link interface, and in the case where an L3 packet can be transmitted from an upper layer. In this case, it will be decided that all L2 configurations configuring the link are completed. Also, the event source is "Local MAC" and "Remote MAC". The parameters of "Link_Up" can be as shown in Table 1.

「Link_Down」出現在一特定介面上釋放一L2連接的情況下，以及在再也無法傳送L3封包的情況下。並且，事件來源為「Local MAC」。「Link_Down」的各項參數可如表2中所示。"Link_Down" occurs when an L2 connection is released on a specific interface, and in the case where the L3 packet can no longer be transmitted.

「Link_Going_Down」出現在估算出一L2連接將會在一特定時間內向下鏈結的情況下。且「Link_Going_Down」可為一為以啟動一遞交程序的信號。而事件來源為「Local MAC」及「Remote MAC」。「Link_Going_Down」的各項參數可如表3中所示。"Link_Going_Down" appears in the case where it is estimated that an L2 connection will be linked down for a certain period of time. And "Link_Going_Down" can be a signal to initiate a delivery procedure. The event sources are "Local MAC" and "Remote MAC". The parameters of "Link_Going_Down" can be as shown in Table 3.

「Link_Going_Up」出現在估算出一L2連接將會在一特定時間內進行「Link_Up」的情況下。並且，在需耗費長時以啟動一網路的情況下，則使用「Link_Going_Up」。而事件來源可為「Local MAC」及「Remote MAC」。「Link_Going_Up」的各項參數可如表4中所示。"Link_Going_Up" appears when it is estimated that an L2 connection will be "Link_Up" for a specific period of time. Also, when it takes a long time to start a network, "Link_Going_Up" is used. The source of the event can be "Local MAC" and "Remote MAC". The parameters of "Link_Going_Up" can be as shown in Table 4.

「Link_Event_Rollback」是與「Link_Going_Up」或「Link_Going_Down」合併運用。此為一觸發器，出現在即使是傳送「Link_Going_Up」或「Link_Going_Down」，而估算出「Link_Going_Up」或「Link_Going_Down」在一特定時間內也不再出現的情況下。而事件來源為「Local MAC」及「Remote MAC」。表5為「Link_Event_Rollback」的各項參數。"Link_Event_Rollback" is used in combination with "Link_Going_Up" or "Link_Going_Down". This is a trigger that appears when "Link_Going_Up" or "Link_Going_Down" is transmitted and "Link_Going_Up" or "Link_Going_Down" is no longer present for a certain period of time. The event sources are "Local MAC" and "Remote MAC". Table 5 shows the parameters of "Link_Event_Rollback".

「Link_Available」表示可使用或可獲用的新特定鏈結。「Link_Available」表示新的基地台或接取點能夠提供佳於一行動用戶站台目前所接取之基地台或接取點的鏈結品質之可能性。而事件來源為「Local MAC」及「Remote MAC」。「Link_Available」的各項參數可如表6中所示。"Link_Available" indicates a new specific link that can be used or available. "Link_Available" indicates that the new base station or access point is capable of providing better link quality than the base station or access point currently accessed by the mobile subscriber station. The event sources are "Local MAC" and "Remote MAC". The parameters of "Link_Available" can be as shown in Table 6.

「Link_Parameters_Change」係一在一鏈結參數值之變異度超過一特定限制的情況下而出現之事件。這可包含一鏈結層參數，像是一鏈結速度、QoS(服務品質)、加密值等等。而事件來源為「Local MAC」及「Remote MAC」。「Link_Parameters_Change」的各項參數可如表7中所示。"Link_Parameters_Change" is an event that occurs when the variability of a link parameter value exceeds a certain limit. This can include a link layer parameter such as a link speed, QoS (Quality of Service), encrypted value, and the like. The event sources are "Local MAC" and "Remote MAC". The parameters of "Link_Parameters_Change" can be as shown in Table 7.

「MIN_Scan」為一由一上層用以發現一目前接取網路之鄰近接取點的命令。若一上層項目請求掃描一可接取網路，則建立該「MIH_Scan」。若請求多個鏈結，則可按照各種媒體掃描請求資訊而開始複數個Link_Scan命令。"MIN_Scan" is a command used by an upper layer to discover a neighboring access point of the current access network. If an upper layer project requests scanning for an accessible network, the "MIH_Scan" is created. If multiple links are requested, multiple Link_Scan commands can be started according to various media scan request information.

MIH_Handover_Initiate.request為一原生項目，此者由一上層項目所使用，藉以在一行動用戶站台的MIH功能與一網路的MIH功能之間遞送一遞交啟動的意向。MIH_Handover_Initiate.request is a native project that is used by an upper-level project to deliver a delivery intent between the MIH function of the mobile subscriber station and the MIH function of a network.

MIH_Handover_Initiate.response為一原生項目，此者可回應於該MIH_Handover_Initiate.request，按照所請求之鏈結的情況而選擇一較適鏈結，藉以表示相對應的資訊。MIH_Handover_Initiate.response is a native project. In response to the MIH_Handover_Initiate.request, the candidate can select a suitable link according to the requested link to indicate the corresponding information.

MIH_Handover_Commit.request訊息是用以藉由通知對於該所選鏈結所大致啟動之遞交的先前接取點，啟動對於透過先前接取點而轉傳(forwarding)至一行動用戶站台之資料而執行的緩衝處理。The MIH_Handover_Commit.request message is used to initiate the forwarding of data to a mobile subscriber station through the previous access point by notifying the previous access point for the delivery initiated for the selected link. Buffer processing.

MIH_Handover_Commit.response訊息為一對於該MIH_Handover_Commit.request訊息的回應訊息，此者用以表示一遞交成功或失敗。The MIH_Handover_Commit.response message is a response message to the MIH_Handover_Commit.request message, which is used to indicate a successful or failed submission.

第4圖係一自經一行動用戶站台所接取之鏈結的品質劣化開始，直到建立一新鏈結為止所出現的觸發器示範性圖式。Figure 4 is an exemplary diagram of the trigger that occurs when the quality of the link taken by the user station has been degraded until a new link is established.

資訊服務提供一對於網路探索及選擇為必要之網路的詳細資訊，並且應能由任意種類的網路所接取。資訊服務應包含像是鏈結接取參數、安全機制、鄰近映圖、位置、服務供應商，以及其他接取資訊、鏈結成本等等的各項資訊要素。The information service provides detailed information about the network necessary for network exploration and selection, and should be accessible from any type of network. Information services should include information elements such as link access parameters, security mechanisms, proximity maps, locations, service providers, and other access information, link costs, and more.

底下說明「行動IPv4」的詳細操作程序。The detailed operation procedure of "Action IPv4" is explained below.

首先，「行動IPv4」的基本目的係為以支援一上層之通透行動性，並且需要行動主機、本家代理器及外部代理器的額外功能。然在不使用路徑最佳化之情況下，即無必要改變與一行動用戶站台進行通訊的相對應節點。在此情況下，該行動主機代表一獲支援而具有行動能力的IP主機。該本家代理器為一路由器，此者可保留該行動主機的位置資訊，並且進行隧穿傳送(tunneling)處理。並且該外部代理器意味者一在一外部網路內支援行動能力的路由器。First of all, the basic purpose of "Action IPv4" is to support the transparency of an upper layer, and it requires additional functions of the mobile host, the home agent and the external agent. However, in the case where path optimization is not used, it is not necessary to change the corresponding node that communicates with a mobile subscriber station. In this case, the mobile host represents a supported and capable IP host. The home agent is a router, which can retain the location information of the mobile host and perform tunneling processing. And the external agent means a router that supports mobility in an external network.

「行動IPv4」的基本動作可如第5圖中所示而解釋。The basic actions of "Action IPv4" can be explained as shown in Figure 5.

底下將說明在第5圖中之逐項步驟的動作。The action of the item by step in Fig. 5 will be explained below.

(1)若一行動主機自其本家網路移離而進入一外部網路內，則該行動主機可藉由接收一來自於該外部網路的公告訊息廣播而辨識出該者既已移動，然後註冊一暫時位址(CoA)，此者可對一在該本家網路內的本家代理器告知其目前位置。(1) If an active host moves out of its home network and enters an external network, the mobile host can recognize that the user has moved by receiving a broadcast of an announcement message from the external network. Then register a temporary address (CoA), which can inform the local agent in the home network of its current location.

(2)在此情況下，CoA係一外部代理器之IP位址(FA－CoA)，或是一由該外部網路透過DHCP等等而指配予該行動主機的位址。自外部發送至該行動主機的封包會被傳送至該本家網路，並且由一可辨知一行動用戶站台移動的本家代理器來撿拾這些封包。(2) In this case, the CoA is an external proxy's IP address (FA-CoA), or an address assigned to the mobile host by the external network via DHCP or the like. Packets sent from the outside to the mobile host are transmitted to the home network and picked up by a local agent that can identify a mobile subscriber station to move.

(3)該本家代理器藉由將FA位址化為一目的地之標的以封裝一經遞送至該行動主機之封包，然後將此遞送至該外部代理器。(3) The home agent encapsulates the packet delivered to the mobile host by addressing the FA address as a destination and then delivers the packet to the external agent.

(4)藉由該外部代理器進行解封裝，以將所遞送之經封裝封包復原成一初始遞送封包，然後最終將其遞送至該行動主機。(4) Decapsulating by the external agent to restore the delivered encapsulated packet to an initial delivery packet and then ultimately delivering it to the mobile host.

(5)待從該行動主機遞送至一相對應主機處之封包可透過該外部代理器而直接地遞送，或者在一進入過濾處理之問題的情況下利用一反向隧道以進行遞送。(5) Packets to be delivered from the mobile host to a corresponding host may be delivered directly through the external agent or may be delivered using a reverse tunnel upon entry into the filtering process.

底下解釋對於「行動IP」為必要的各項主要功能。The main functions necessary for "Action IP" are explained below.

1)代理器探索代理器探索是一種決定一行動用戶站台目前究係經連接至其本家網路或現位在一外部網路處的方法。藉此方法，該行動用戶站台可偵測出該者既已移入至另一網路內。1) Agent Exploration Agent Exploration is a method of determining whether a mobile subscriber station is currently connected to its home network or is located at an external network. In this way, the mobile subscriber station can detect that the subscriber has moved into another network.

「行動IP」可延展傳統的ICMP(網際網路控制訊息協定)路由器發現[IETF RFC 1256]。一由一代理器(本家代理器、外部代理器)所週期性地廣播的代理器公告訊息可將一行動代理器公告延伸納入在一待予傳送之ICMP路由器公告訊息內。由一行動用戶站台所傳送藉以尋找一代理器的「Router Solicit」訊息是運用與一傳統「ICMP Router Solicit」訊息相同的方法。"Mobile IP" extends the traditional ICMP (Internet Control Message Protocol) router discovery [IETF RFC 1256]. An agent announcement message periodically broadcast by an agent (home agent, external agent) may extend an action agent announcement into an ICMP router announcement message to be transmitted. The "Router Solicit" message transmitted by a mobile subscriber station to find an agent is the same method as a conventional "ICMP Router Solicit" message.

2)註冊一註冊功能可提供一種在一行動用戶站台偵測到其遷移至另一網路內的情況下，依照將目前位置資訊遞交至一本家代理器之方式，使得一在一本家網路上提供之服務能夠在一新網路上提供的彈性機制。「行動IP」定義兩種不同的註冊程序。若使用FA－CoA，則一行動用戶站台應透過一外部代理器進行註冊。若使用共置CoA，則一行動用戶站台對一本家代理器直接地註冊。2) The registration-registration function can provide a way to submit the current location information to a home agent in a way that the mobile station station detects its migration to another network, so that it is on a home network. The service provided provides a flexible mechanism on a new network. "Action IP" defines two different registration procedures. If FA-CoA is used, an mobile subscriber station should be registered through an external agent. If a co-located CoA is used, an mobile subscriber station registers directly with a home agent.

3)路由處理若一行動用戶站台經鏈結於一外部網路，即需要一種路由傳送功能以往返於該行動用戶站台而適當地路由傳送各資料包。資料包含有多重廣播與廣播封包，以及單一廣播封包。3) Routing Processing If an active subscriber station is linked to an external network, a routing function is required to route the packets appropriately to and from the mobile subscriber station. The data includes multiple broadcast and broadcast packets, as well as a single broadcast packet.

第6圖係一為以解釋一根據相關技藝之「行動IPv6」的基本運作圖。Figure 6 is a diagram for explaining the basic operation of "Action IPv6" according to the related art.

首先，可在第6圖中循序地說明「行動IPv6」的各項運作步驟。First, the operational steps of "Mobile IPv6" can be described sequentially in Figure 6.

0.MN自子網路A移離而進入子網路B。0. MN moves away from subnet A and enters subnet B.

1.MN利用RA訊息的字首資訊以及NUD(鄰者無可觸及偵測)機制而偵測出一遷移情況。1. MN uses the prefix information of the RA message and the NUD (Neighbor Impaired Detection) mechanism to detect a migration.

2.透過「Address auto－configuration」而由其本身獲得CoA。2. Get the CoA by itself through "Address auto-configuration".

3.發送BU訊息以通知HA所獲得的CoA。3. Send a BU message to inform the HA of the CoA obtained.

4. HA將該MN的本家位址與該CoA綁接合一，並且接著回應於BU而發送BACK。4. The HA binds the home address of the MN to the CoA, and then sends a BACK in response to the BU.

5.最先與MN進行通訊的CN因為無法偵測到MN的遷移，而藉由將一目的地位址組態至該MN的本家位址以傳送一封包。5. The CN that first communicates with the MN cannot transmit a packet by configuring a destination address to the home address of the MN because it cannot detect the migration of the MN.

6.管理MN之HA截獲該封包，藉以將其隧穿傳送至一MN的目前位置。6. The HA managing the MN intercepts the packet, thereby tunneling it to the current location of a MN.

7.接收到該經隧穿傳送之封包的MN決定該CH並不具有綁接資訊，然後藉由將BU訊息發送至該CN以通知其CoA的CN。7. The MN receiving the tunneled packet determines that the CH does not have the binding information, and then notifies its CN of the CoA by sending a BU message to the CN.

8.在既已儲存該綁接資訊之後，CN即利用該資訊以與MN直接地通訊。8. After the binding information has been stored, CN uses the information to communicate directly with the MN.

第7圖及第8圖為用以解釋FMIPv6之各項運作處理的圖式。第7圖顯示一在「主動(Proactive)」模式下的操作程序，而第8圖顯示一在「反應(Reactive)」模式下的操作程序。有為以往返於一RAR鏈結而發送FBU/FBACK訊息之「Proactive」模式，以及為以往返於一NAR鏈結而發送FBU/FBACK訊息的「Reactive」模式。在「Proactive」模式下，在將一接至PAR的連接予以釋放之前，會先檢查所建立NCoA的確定性。而在「Reactive」模式下，則是在一行動節點確已抵達一新的子網路之後檢查NCoA的確定性。Figures 7 and 8 are diagrams for explaining the operational processing of FMIPv6. Figure 7 shows an operating procedure in "Proactive" mode, while Figure 8 shows an operating procedure in "Reactive" mode. There is a "Proactive" mode for sending FBU/FBACK messages to and from a RAR link, and a "Reactive" mode for sending FBU/FBACK messages to and from a NAR link. In "Proactive" mode, the certainty of the established NCoA is checked before releasing the connection to the PAR. In "Reactive" mode, the certainty of the NCoA is checked after a mobile node has arrived at a new subnet.

底下將參照第7圖以說明「Proactive mode」的操作程序。The operation procedure of "Proactive mode" will be explained below with reference to Fig. 7.

1)一行動節點根據L2層資訊(即如在一無線LAN系統中進行掃描)而發現可獲用以進行遞交的各AP，然後將RtSolPr訊息發送至PAR，藉以獲得對應於所發現之AP識別碼的子網路資訊。1) A mobile node discovers each AP that can be used for delivery according to the L2 layer information (ie, scanning in a wireless LAN system), and then sends the RtSolPr message to the PAR to obtain the AP identification corresponding to the discovery. Subnet information for the code.

2)既已收到RtSolPr訊息之PAR將對應於各AP的子網路訊息按[AP－ID,AR－Info]格式放置在元組(tuple)內，然後將一PrRtAdv訊息發送至該行動節點。在該行動節點已執行過路由器偵測作業之後，有時可按「Solicit(懇請)」發送此訊息。2) The PAR that has received the RtSolPr message places the subnet message corresponding to each AP in a tuple in the [AP-ID, AR-Info] format, and then sends a PrRtAdv message to the action node. . After the mobile node has performed the router detection job, sometimes you can send this message by pressing "Solicit".

3)該行動節點根據PrRtAdv訊息內的AR－Info，建立一個新的轉交位址(NCoA)。3) The mobile node establishes a new care-of address (NCoA) based on the AR-Info in the PrRtAdv message.

4)該行動節點發送FB訊息，其中請求該PAR將PCoA及NCoA綁接合一，使得能夠將抵達該PAR的各封包隧穿傳送至NAR。4) The mobile node sends an FB message, in which the PAR is requested to bind the PCoA and the NCoA to one, so that each packet arriving at the PAR can be tunneled to the NAR.

5)該PAR發送一通知訊息，此者表示該行動節點將遞交至該NAR，亦即HI。而接收到該HI訊息的NAR執行一由該行動節點所建立之NCoA的重疊檢查。若因該重疊檢查之故而該NCoA並不適合，則該NAR會對於該行動節點新另地組態一CoA。5) The PAR sends a notification message indicating that the mobile node will submit to the NAR, ie HI. The NAR receiving the HI message performs an overlap check of the NCoA established by the mobile node. If the NCoA is not suitable due to the overlap check, the NAR will newly configure a CoA for the action node.

6)該NAR對該PAR發送HACK，以作為對於該HI之回應訊息。在此情況下，可將一新建立之NCoA納入。6) The NAR sends a HACK to the PAR as a response message to the HI. In this case, a newly established NCoA can be included.

7)接收到該HACK的PAR將FBACK發送至該行動節點與該NAR，並通知該PAR將會啟動，藉以將該行動節點之一封包隧穿傳送至一真實NCoA的位址處。在此情況下，即將一在該行動節點與該PAR之間的連接予以釋放。7) The PAR that received the HACK sends the FBACK to the mobile node and the NAR, and informs the PAR that it will start, thereby tunneling a packet of the mobile node to a real NCoA address. In this case, a connection between the mobile node and the PAR is released.

8)將既已抵達該PAR處的封包轉傳至該NAR處。8) Transfer the packet that has arrived at the PAR to the NAR.

9)當既已建妥一接至該NAR的新鏈結之後，該行動節點隨即將FNA訊息發送至該NAR。因此，會通知該行動節點本身現經連接至該NAR之一網路。9) After the new link to the NAR has been established, the mobile node then sends an FNA message to the NAR. Therefore, the mobile node itself is notified that it is now connected to one of the NAR networks.

10)透過NAR以傳送封包。10) Transmit the packet through the NAR.

同時，底下將參照第8圖以說明「Reactive mode」的操作程序。At the same time, the operation procedure of "Reactive mode" will be explained below with reference to Fig. 8.

1)一行動節點根據L2層資訊(即如在一無線LAN系統中進行掃描)而發現可獲用以進行遞交的各AP，然後將RtSolPr訊息發送至PAR，藉以獲得對應於所發現之AP識別碼的子網路資訊。1) A mobile node discovers each AP that can be used for delivery according to the L2 layer information (ie, scanning in a wireless LAN system), and then sends the RtSolPr message to the PAR to obtain the AP identification corresponding to the discovery. Subnet information for the code.

2)既已收到RtSolPr訊息之PAR將對應於各AP的子網路訊息按[AP－ID,AR－Info]格式放置在元組(tuple)內，然後將一PrRtAdv訊息發送至該行動節點。在該行動節點已執行過路由器偵測作業之後，有時可按「Solicit」發送此訊息。2) The PAR that has received the RtSolPr message places the subnet message corresponding to each AP in a tuple in the [AP-ID, AR-Info] format, and then sends a PrRtAdv message to the action node. . After the mobile node has performed a router detection job, sometimes this message can be sent by pressing "Solicit".

3)該行動節點根據PrRtAdv訊息內的AR－Info，建立一個新的轉交位址(NCoA)。3) The mobile node establishes a new care-of address (NCoA) based on the AR-Info in the PrRtAdv message.

4)一旦確經連接至該NAR之後，該行動節點立即地按一將FBU訊息裹裝在FNA訊息之內的方式，啟動一將一抵達封包轉傳至該NAR的程序。並且，該行動節點令該NAR檢查該NCoA是否為有效。4) Once it is connected to the NAR, the mobile node immediately initiates a procedure for forwarding the incoming packet to the NAR in a manner that wraps the FBU message within the FNA message. And, the action node causes the NAR to check if the NCoA is valid.

5)該NAR將FB訊息發送至該PAR，以將PCoA及NCoA綁接合一。若在該NAR所接收到之FBU內該NCoA並非有效，則該NAR拋除FBU封包並發送一路由器公告，而其內具有一替代位址。5) The NAR sends an FB message to the PAR to tie the PCoA and the NCoA to one. If the NCoA is not valid in the FBU received by the NAR, the NAR discards the FBU packet and sends a router advertisement with an alternate address therein.

6)該PAR對該NAR發送FBACK，以作為對於該FBU的回應訊息。在此情況下，即在一真實PAR與NAR間完成一隧穿傳送建立作業。6) The PAR sends a FBACK to the NAR as a response message to the FBU. In this case, a tunneling transfer setup operation is completed between a real PAR and a NAR.

7)將既已抵達該PAR處的封包轉傳至該NAR處。7) Transfer the packet that has arrived at the PAR to the NAR.

8)透過NAR以傳送封包。8) Transmit the packet through the NAR.

然而，即如前文中所敘述，該相關技藝具有下列問題。However, as described in the foregoing, the related art has the following problems.

首先，在使用MIPv4、MIPv6或FMIPv6的情況下，是按獨立方式產生該L2遞交程序及該L3遞交程序。換言之，是在既已完成該L2遞交之後方才進行該L3遞交。因此會出現相對應的延遲。First, in the case of using MIPv4, MIPv6 or FMIPv6, the L2 delivery procedure and the L3 delivery procedure are generated in an independent manner. In other words, the L3 submission is made only after the L2 submission has been completed. Therefore, there will be a corresponding delay.

其次，若一知悉該L2遞交之網路直接地發送出對於L3遞交的訊息，則該L3對此並不瞭解。從而會需要一個毫無必要的訊息傳輸。Secondly, if it is known that the L2-submitted network directly sends the message submitted for L3, the L3 does not know about it. This will require an unnecessary transmission of information.

第三，若是對於施用本發明之領域確可獲用各媒體獨立遞交項目之間的通訊，則當於各同質(homogeneous)網路之間進行一遞交時，即無需改變而能夠使用於IP位址重新設置。Third, if the communication between the independent submission projects of the media is indeed available for the field to which the present invention is applied, when a delivery is made between the homogeneous networks, the IP address can be used without change. Address reset.

從而，本發明係針對於一種在各異質網路間進行遞交時將一IP位址重新設置的方法，此者可大幅地減輕一或更多因相關技藝之限制與缺點所致生的問題。Accordingly, the present invention is directed to a method of resetting an IP address when delivering between heterogeneous networks, which can substantially alleviate one or more problems due to limitations and disadvantages of the related art.

第9圖為一根據本發明之一較佳具體實施例的流程圖。Figure 9 is a flow chart of a preferred embodiment of the present invention.

若一行動用戶站台利用MIPv4或MIPv6作為一行動支援協定，並以FA－CoA或非狀態型式位址資訊作為轉交位址(Care of Address,CoA)，同時若在進行遞交時將一新PoA之FA－CoA或非狀態型式位址自一舊PoA配置至該新PoA，則可藉由一資訊服務以取得對於該新PoA的MAC位址。在本發明之說明中，該詞彙「舊」可與詞彙「來源」及/或「先前」互換地運用。If an mobile subscriber station uses MIPv4 or MIPv6 as an action support agreement, and uses FA-CoA or non-state type address information as the Care of Address (CoA), and if a new PoA is to be submitted The FA-CoA or non-state type address is configured from an old PoA to the new PoA, and an information service is used to obtain a MAC address for the new PoA. In the description of the present invention, the term "old" may be used interchangeably with the terms "source" and/or "previously".

1)若一信號品質劣化，則一行動用戶站台的先前鏈結可透過MIH將Link_Going_Down傳送至一含有一上層管理項目之上層，並亦將含有一新PoA至一舊/先前PoA之位址的Remote_Link_Going_Down傳送至一舊PoA。在此情況下，該行動用戶站台之一MIH即觸發以將IP_Information.request轉傳至該舊PoA，而非轉傳該Remote_Link_Going_Down。該MIH藉由先前指示對各較低鏈結層進行週期性掃描，藉以獲得對於一可用鏈結層之資訊，並由該上層管理項目指示一各候選鏈結層之列表，藉以維護相對應的資訊。1) If a signal quality deteriorates, the previous link of a mobile subscriber station can transmit Link_Going_Down through MIH to an upper layer containing an upper management item, and will also contain a new PoA to an old/previous PoA address. Remote_Link_Going_Down is transferred to an old PoA. In this case, one of the mobile subscriber stations MIH is triggered to forward IP_Information.request to the old PoA instead of forwarding the Remote_Link_Going_Down. The MIH periodically scans the lower link layers by the previous indication to obtain information about an available link layer, and indicates a list of candidate link layers by the upper management item, thereby maintaining the corresponding News.

2)舊PoA之MIH藉由與該新PoA的MIH交換Inter_MIH.query及Inter_MIH.response，獲得顯現或未顯現一CoA(「轉交位址」)變化的結果。此外，舊PoA的MIH在透過此訊息交換而先前地通知該新PoA一特定行動用戶站台將啟動一至該新PoA之遞交過程中扮演一角色。因此，該新PoA可藉由向該舊PoA請求該資訊，以獲得對於特定行動用戶站台之遞交的額外必要資訊。透過此處理程序，一含有該舊PoA之來源網路與一含有該新PoA之目標網路兩者可建立遞交管理模組，此者可含有一網路遞交模式(即如MIH)、一行動管理模組/項目、一使用者平面模組/項目(UPE)、一行動網際網路協定外部代理器及一接取路由器之任一者。在此，該來源網路可進一步包含舊/先前的外部代理器/接取路由器，同時該目標網路可進一步包含新的外部代理器/接取路由器。如上所使用之詞彙並不受限在對於第9圖之說明，而是亦可透過本發明說明加以運用。2) The MIH of the old PoA obtains the result of a change in CoA ("transfer address") manifested or not by exchanging Inter_MIH.query and Inter_MIH.response with the MIH of the new PoA. In addition, the old PoA's MIH has previously notified the new PoA that a particular mobile subscriber station will initiate a role in the delivery of the new PoA through this exchange of information. Therefore, the new PoA can obtain additional necessary information for the delivery of the specific mobile subscriber station by requesting the information from the old PoA. Through this processing procedure, a source network containing the old PoA and a target network containing the new PoA can establish a delivery management module, which can include a network delivery mode (ie, MIH), an action Management module/project, a user plane module/project (UPE), a mobile internet protocol external agent, and an access router. Here, the source network may further include an old/previous external agent/access router, and the target network may further include a new external agent/access router.

8)該新PoA的MIH藉由將一含有IP位址資訊之IP_Information.confirm訊息發送該舊PoA的MIH以進行回應。換種說法，該目標網路之遞交管理模組將一對於有關遞交之請求訊息的回應訊息發送至該來源網路的遞交管理模組。8) The MIH of the new PoA responds by sending an IP_Information.confirm message containing the IP address information to the MIH of the old PoA. In other words, the delivery management module of the target network sends a response message to the request message submitted to the delivery management module of the source network.

9)該舊PoA的MIH將含有IP位址資訊之New_IP_Address.indication觸發至該行動用戶站台之上層的MIH。亦即，該來源網路的遞交管理模組將一用以遞交而其中含有網際網路協定位址資訊的確認訊息發送至該行動終端/行動用戶站台。9) The MIH of the old PoA triggers the New_IP_Address.indication containing the IP address information to the MIH above the mobile subscriber station. That is, the delivery management module of the source network sends a confirmation message for submitting the information including the Internet Protocol address to the mobile terminal/mobile user station.

10)即已建妥與該新PoA的第2層(L2)鏈結。10) The Layer 2 (L2) link with the new PoA has been established.

11)~12)該行動用戶站台之一新鏈結可觸發對於含有該上層管理項目之上層的Link_Up，並亦觸發對於該新PoA之MIH的Remote_Link_Up。在此情況下，若該新PoA本身辨識出係透過其MAC層而組態一新連接，則該新PoA的MAC層可將此者直接地觸發至該MIH。11)~12) A new link of the mobile subscriber station may trigger a Link_Up for the upper layer containing the upper management item and also trigger a Remote_Link_Up for the MIH of the new PoA. In this case, if the new PoA itself recognizes that a new connection is configured through its MAC layer, the MAC layer of the new PoA can directly trigger the person to the MIH.

13)該行動用戶站台的上層將一註冊請求訊息傳送至一本家代理器。13) The upper layer of the mobile subscriber station transmits a registration request message to a home agent.

14)該本家代理器將「Registration Response」回應至該行動用戶站台的上層。14) The home agent responds to the upper layer of the mobile subscriber station with "Registration Response".

第11圖為一根據本發明之另一較佳具體實施例的流程圖。Figure 11 is a flow chart showing another preferred embodiment of the present invention.

若一行動用戶站台利用MIPv4或MIPv6作為一行動支援協定，並以一FA－CoA或非狀態型式位址資訊作為轉交位址(CoA)，則在進行自一舊PoA至該新PoA的遞交中，將對於一新PoA配置一FA－CoA或一非狀態型式位址。If an mobile subscriber station uses MIPv4 or MIPv6 as an action support agreement and uses a FA-CoA or non-state type address information as the handover address (CoA), then the submission from the old PoA to the new PoA is performed. A FA-CoA or a non-state type address will be configured for a new PoA.

參照第11圖，在一新外部代理器或新接取路由器(5)，經通知一特定行動用戶站台將對其進行遞交，該新外部代理器透過一舊外部代理器，藉由隧穿傳送(6)將「Agent Advertisement」傳送(7)至該行動用戶站台。並且，該新接取路由器透過一舊接取路由器，藉由隧穿傳送(7)將「Router Advertisement」傳送(7)至該行動用戶站台。如此進行，則該舊外部代理器或該舊接取路由器可透過解隧穿傳送處理以將其提供至該行動用戶站台。Referring to FIG. 11, a new external agent or a new access router (5) is notified by a specific mobile subscriber station, and the new external proxy transmits the tunnel through an old external proxy. (6) Transfer (7) the "Agent Advertisement" to the mobile subscriber station. Moreover, the new access router transmits (7) the "Router Advertisement" to the mobile subscriber station through tunneling transmission (7) through an old access router. In so doing, the old external agent or the old access router can perform tunneling transmission processing to provide the mobile subscriber station to the mobile subscriber station.

在步驟(7)內會表現出該「Proxy Agent/Router Advertisement」，因為該舊外部代理器或該舊接取路由器中繼傳送該經轉傳之「Agent Advertisement」或「Router Advertisement」，而非傳送其「Agent Advertisement」或「Router Advertisement」。The "Proxy Agent/Router Advertisement" will be displayed in the step (7) because the old external agent or the old access router relays the transferred "Agent Advertisement" or "Router Advertisement" instead of Send its "Agent Advertisement" or "Router Advertisement".

並且，本具體實施例之其餘步驟類似於在第9圖中所示具體實施例所解釋者。Moreover, the remaining steps of this embodiment are similar to those explained in the specific embodiment shown in FIG.

第12圖為一根據本發明之另一較佳具體實施例的流程圖。Figure 12 is a flow chart of another preferred embodiment of the present invention.

若一行動用戶站台利用MIPv4或MIPv6作為一行動支援協定，並以一FA－CoA或非狀態型式位址資訊作為轉交位址(CoA)，則在進行自一舊PoA至該新PoA的遞交中，將對一新PoA配置一FA－CoA或一非狀態型式位址。If an mobile subscriber station uses MIPv4 or MIPv6 as an action support agreement and uses a FA-CoA or non-state type address information as the handover address (CoA), then the submission from the old PoA to the new PoA is performed. A new PoA will be configured with a FA-CoA or a non-state type address.

參照第12圖，一舊外部代理器或一舊接取路由器接收並維護鄰近外部代理器或接取路由器的資訊，即如(1)、(2)。可對其本身週期性地進行，或可按照一請求非週期地進行，該資訊維護作業。Referring to Fig. 12, an old external agent or an old access router receives and maintains information adjacent to the external agent or the access router, as in (1), (2). This may be done periodically, or may be performed aperiodically as requested, and the information maintains the job.

步驟(3)、(4)及(5)類似於第9圖中所示之步驟(1)及(2)。同時，一行動用戶站台的MIH可觸發(轉傳)IP_Information.request，而非觸發Remote_Link_Going_Down。Steps (3), (4), and (5) are similar to steps (1) and (2) shown in Fig. 9. At the same time, the MIH of an active subscriber station can trigger (transfer) IP_Information.request instead of triggering Remote_Link_Going_Down.

一舊PoA的MIH將IP_Information.request傳送至該舊外部代理器或該接取路由器的MIH，藉以請求一特定行動用戶站台將移往以與此進行連接之新PoA的接取路由器位址資訊或FA(外部代理器)位址資訊(6)。The MIH of an old PoA transmits IP_Information.request to the old external proxy or the MIH of the access router, thereby requesting that a specific mobile subscriber station will move to the access router address information of the new PoA connected with this or FA (external agent) address information (6).

將一相對應的原生項目自該MIH而遞送至一上層。在此情況下，可通透地遞送該原生項目(7)。或另者，可轉換該原生項目以進行遞送(7)。A corresponding native item is delivered from the MIH to an upper layer. In this case, the native item (7) can be delivered transparently. Alternatively, the native item can be converted for delivery (7).

若所請求之該新PoA的接取路由器位址資訊或FA位址資訊存在於由該舊外部代理器或接取路由器所維護的資訊列表內，則將現存的資訊遞送至該行動用戶站台(8)。If the requested router address information or FA address information of the new PoA is present in the information list maintained by the old external agent or the access router, the existing information is delivered to the mobile user station ( 8).

並且，本具體實施例之其餘步驟類似於在第9圖中所示具體實施例所解釋者。Moreover, the remaining steps of this embodiment are similar to those explained in the specific embodiment shown in FIG.

第13圖為一根據本發明之另一較佳具體實施例的流程圖。Figure 13 is a flow chart showing another preferred embodiment of the present invention.

若一行動用戶站台利用MIPv4或MIPv6作為一行動支援協定，並以一FA－CoA或非狀態型式位址資訊作為轉交位址(CoA)，則在進行自一舊PoA至該新PoA的遞交中，將對於一新PoA配置一FA－CoA或一非狀態型式位址。If an mobile subscriber station uses MIPv4 or MIPv6 as an action support agreement and uses a FA-CoA or non-state type address information as the handover address (CoA), then the submission from the old PoA to the new PoA is performed. A FA-CoA or a non-state type address will be configured for a new PoA.

參照第13圖，一舊外部代理器或接取路由器的MIH傳送一原生項目，此者請求應將一新PoA之外部代理器或接取路由器的經遞送位址資訊傳送至該舊外部代理器或接取路由器的上層(8)。Referring to Figure 13, an old external agent or the MIH of the receiving router transmits a native item, which requests that the delivery address information of the external agent of the new PoA or the receiving router should be transmitted to the old external agent. Or pick up the upper layer (8) of the router.

該具有所接收原生項目之上層將經遞送之資訊傳送至一行動用戶站台(9)。The upper layer of the received native item transmits the delivered information to a mobile subscriber station (9).

若仍能維持一於該行動用戶站台與該舊鏈結之間的連接，則該行動用戶站台將對於一註冊作業之「Registration Request」透過該舊鏈結而傳送至一本家代理器(10)。If the connection between the mobile subscriber station and the old link is still maintained, the mobile subscriber station transmits a "Registration Request" for a registration operation to the home agent through the old link (10). .

經傳送至該本家代理器的註冊請求訊息係透過一新外部代理器所中繼傳送。該本家代理器將一為以同意該行動用戶站台之註冊的回應訊息傳送至該新外部代理器。既已收到該回應訊息後，該新外部代理器將此保留直到自一PoA觸發Link_Up為止，而非立即地將其轉傳至該行動用戶站台(11)。The registration request message transmitted to the home agent is relayed through a new external agent. The home agent will transmit a response message to the new external agent in agreement with the registration of the mobile subscriber station. After receiving the response message, the new external agent retains this until a Link_Up is triggered from a PoA, instead of immediately forwarding it to the mobile subscriber station (11).

該行動用戶站台執行一新鏈結組態程序。一旦設妥此鏈結後，該行動用戶站台被通知以完成新鏈結(13)，並亦對一新PoA(遠端)通知此結果(14)。在該新PoA為其本身管理一與該行動用戶站台之鏈結狀態的情況下。在此情況下，可省略對「Remote」通知該鏈結組態的程序。The mobile subscriber station performs a new link configuration procedure. Once the link is set, the mobile subscriber station is notified to complete the new link (13) and also informs the new PoA (remote) of the result (14). In the case where the new PoA manages its own link state with the mobile subscriber station. In this case, the program that notifies the link configuration of "Remote" can be omitted.

當將Link_Up遞送至該新PoA之MIH及上層時，即連同該行動用戶站台之鑑別器一起傳送，以表示該行動用戶站台所向上鏈結者為何。該新PoA的MIH通知該新外部代理器或接取路由器既已設妥該行動用戶站台的鏈結(15)。When the Link_Up is delivered to the MIH and the upper layer of the new PoA, it is transmitted along with the discriminator of the mobile subscriber station to indicate why the mobile subscriber station is up chained. The MIH of the new PoA informs the new external agent or the access router that the link to the mobile subscriber station has been set up (15).

由於該新外部代理器或接取路由器被通知既已完成該特定行動用戶站台之鏈結組態，因此該外部代理器或接取路由器發送「Registration Reply」，表示確已完成由該相對應之行動用戶站台透過該舊鏈結而發送至該本家代理器的註冊程序(16)。由相同的本家代理器轉傳該「Registration Reply」。該外部代理器或接取路由器在連同Link_Up通知而傳送，然非予以處理，過程中扮演一角色。Since the new external agent or the access router is notified that the link configuration of the specific mobile subscriber station has been completed, the external proxy or the access router sends a "Registration Reply", indicating that the corresponding one has been completed. The mobile subscriber station sends the registration procedure (16) to the home agent through the old link. The "Registration Reply" is forwarded by the same local agent. The external agent or the pick-up router transmits it along with the Link_Up notification, but does not process it, playing a role in the process.

並且，本具體實施例之其餘步驟類似於在第9圖中所示具體實施例所解釋者。Moreover, the remaining steps of this embodiment are similar to those explained in the specific embodiment shown in FIG.

第14圖為一根據本發明之另一較佳具體實施例的流程圖。Figure 14 is a flow chart of another preferred embodiment of the present invention.

若一行動用戶站台利用MIPv4或MIPv6作為一行動支援協定，並以一FA－CoA或非狀態型式位址資訊作為轉交位址(CoA)，則在進行自一舊PoA至該新PoA的遞交中，將對於一新PoA配置一FA－CoA或一非狀態型式位址。If an mobile subscriber station uses MIPv4 or MIPv6 as an action support agreement and uses a FA-CoA or non-state type address information as the handover address (CoA), then the submission from the old PoA to the new PoA is performed. A FA-CoA or a non-state type address will be configured for a new PoA.

參照第14圖，若因一鏈結已自一舊PoA而釋放等等之原因無法將該位址資訊轉傳至一行動用戶站台，則一旦設妥一與一新PoA之鏈結後(10)，該新PoA即傳送由該新PoA所接收並保留的位址資訊(「代理器公告)或「路由器公告」)(11)。在此情況下，若該新PoA之一鏈結層可辨識出一對於其本身的新連接，則可對其MIH直接地通知該鏈結組態資訊。Referring to Fig. 14, if the address information cannot be transferred to an action user station due to the fact that a link has been released from an old PoA, etc., once the link with a new PoA is set (10) The new PoA transmits the address information ("Proxy Announcement" or "Router Announcement") (11) received and retained by the new PoA. In this case, if one of the link layers of the new PoA can recognize a new connection for itself, the MIH can directly notify the link configuration information.

並且，本具體實施例之其餘步驟類似於在第9圖中所示具體實施例所解釋者。Moreover, the remaining steps of this embodiment are similar to those explained in the specific embodiment shown in FIG.

第15圖為一根據本發明之另一較佳具體實施例的流程圖。Figure 15 is a flow chart showing another preferred embodiment of the present invention.

若一行動用戶站台利用MIPv4或MIPv6作為一行動支援協定，並以一FA－CoA或非狀態型式位址資訊作為轉交位址(CoA)，則在進行自一舊PoA至該新PoA的遞交中，將對於一新PoA配置一FA－CoA或一非狀態型式位址。If an mobile subscriber station uses MIPv4 or MIPv6 as an action support agreement and uses a FA-CoA or non-state type address information as the handover address (CoA), then the submission from the old PoA to the new PoA is performed. A FA-CoA or a non-state type address will be configured for a new PoA.

參照第15圖，若因一鏈結已自一舊PoA而釋放等等之原因無法將該位址資訊轉傳至一行動用戶站台，則一新PoA通知一新外部代理器或接取路由器既已設妥一與該新PoA之鏈結(10)、(11)及(12)。一旦設妥該行動用戶站台之新PoA的鏈結後，該新外部代理器或接取路由器即傳送該位址資訊(「代理器公告」或「路由器公告」)(13)。Referring to Fig. 15, if the address information cannot be transferred to an mobile subscriber station due to the fact that a link has been released from an old PoA, etc., a new PoA notifies a new external agent or the access router. The links (10), (11) and (12) with the new PoA have been set. Once the new PoA link of the mobile subscriber station is set, the new external proxy or the access router transmits the address information ("Proxy Announcement" or "Router Advertisement") (13).

並且，本具體實施例之其餘步驟類似於在第9圖中所示具體實施例所解釋者。Moreover, the remaining steps of this embodiment are similar to those explained in the specific embodiment shown in FIG.

第16圖為一根據本發明之另一較佳具體實施例的流程圖，其中使用FMIPv6(於傳送Link_Going_Down時，一待行遞交之另一型式的介面之PoA位址為已知)。Figure 16 is a flow diagram of another preferred embodiment of the present invention in which FMIPv6 is used (when the Link_Going_Down is transmitted, the PoA address of another type of interface to be submitted is known).

(1)發現到一目前所接取之鏈結的狀態正在劣化。並且，將一Link_Going_Down觸發器傳送至需要此項資訊的MIH及上層。(1) It is found that the state of a currently attached link is deteriorating. Also, a Link_Going_Down trigger is sent to the MIH and the upper layer that need this information.

(2)也會將表示該鏈結正在劣化之資訊傳送至一目前所接取之PoA的MIH層。可透過目前所接取之鏈結利用第2層，或是利用第3層或以上，來進行此資訊傳輸作業。該資訊含有一待予新近接取之PoA的位址(接附點)。可事先透過一資訊服務或一鄰者公告獲得該新PoA的位址。該MIH藉由先前分別地指示對各較低鏈結層進行週期性掃描，藉以獲得對於一可用鏈結層之資訊，並由該上層管理項目指示一各候選鏈結層之列表，藉以維持相對應的資訊。(2) The information indicating that the link is deteriorating is also transmitted to the MIH layer of the currently accessed PoA. This information transfer operation can be performed by using the second layer or the third layer or above through the currently accessed link. The information contains the address (attachment point) of the PoA to be newly accessed. The address of the new PoA can be obtained in advance through an information service or a neighbor announcement. The MIH maintains a phase by periodically instructing periodic scans of the lower link layers to obtain information about an available link layer, and indicating a list of candidate link layers by the upper management item. Corresponding information.

(3)目前所接取之PoA的MIH利用由Link_Going_Down所載荷之新PoA位址，藉由與一新PoA的MIH交換資訊(Inter MIH Query & ResponSe)以獲得該新PoA的網路情況資訊。在此情況下，該行動用戶站台的MIH可將IP_Information.request傳送至該目前PoA，而非傳送Link_Going_Down(不需改變IP位址)。新的網路情況資訊提供一種由一PoA所使用的行動管理協定，而該PoA係由該行動用戶站台所新近地接取，以及在相同行動管理協定之情況下根據該行動管理協定的資訊，亦即在MIPv4的情況下表示一FA是否等同於一目前PoA者之資訊，以及表示一經連接至一目前PoA之接取路由器是否等同於一新PoA者等等的資訊。在此情況下，亦可獲得一經連接至該新PoA之接取路由器的資訊。此外，目前所接取之PoA的MIH在透過此訊息交換而事先地通知該新PoA一特定行動用戶站台將啟動一至該新PoA之遞交過程中扮演一角色。因此，該新PoA可向該舊PoA提供請求，以獲得對於該特定行動用戶站台之遞交所必要的額外資訊。(3) The MIH of the currently received PoA uses the new PoA address carried by the Link_Going_Down to exchange information (Inter MIH Query & ResponSe) with the MIH of a new PoA to obtain the network status information of the new PoA. In this case, the MIH of the mobile subscriber station can transmit IP_Information.request to the current PoA instead of transmitting Link_Going_Down (without changing the IP address). The new network situation information provides an action management agreement used by a PoA, which is newly received by the mobile subscriber station and, in the case of the same operational management agreement, based on the information of the operational management agreement, That is, in the case of MIPv4, it is indicated whether an FA is equivalent to information of a current PoA, and information indicating whether an access router connected to a current PoA is equivalent to a new PoA or the like. In this case, information about the access router connected to the new PoA can also be obtained. In addition, the MIH of the currently received PoA plays a role in informing the new PoA that a specific mobile subscriber station will initiate a delivery to the new PoA through this message exchange. Thus, the new PoA can provide a request to the old PoA to obtain additional information necessary for the submission of the particular mobile subscriber station.

(4)可利用IP資訊請求來通知該目前PoA之接取路由器，關於該特定行動用戶站台將移動至一經連接至該新PoA之接取路由器。此具有與在FMIPv6中，從該行動用戶站台傳送RtSolPr(路由器懇請代理器)相同的效果。然而，由於是該網路引導一觸發器，而非該行動用戶站台獲得顯現或未顯現其遷移情況以傳送該RtSolPr，因此可具有能夠省略自該行動用戶站台發送RtSolPr訊息的效果。(4) The IP information request can be used to notify the current PoA access router that the subscriber station will move to the access router that is connected to the new PoA. This has the same effect as transmitting RtSolPr (router request agent) from the mobile subscriber station in FMIPv6. However, since the network bootstrap trigger, instead of the mobile subscriber station obtaining or not showing its migration to transmit the RtSolPr, there may be an effect that the RtSolPr message can be omitted from the mobile subscriber station.

(5)該目前所接取之接取路由器藉由發送自該MIH之觸發器，對該新PoA的接取路由器傳送PrRtrAdv(代理器路由器公告)。經此方式，相較於行動用戶站台的RtSolPr，確可更快速地傳送該PrRtrAdv。(5) The currently accessed pick-up router transmits a PrRtrAdv (Proxy Router Advertisement) to the pick-up router of the new PoA by means of a trigger sent from the MIH. In this way, the PrRtrAdv can be transmitted more quickly than the RtSolPr of the mobile subscriber station.

(6)一多重模式行動用戶站台組態一新的「Careof Address(CoA)」，此者可透過所傳PrRtrAdv，而由經連接至該新PoA之新接取路由器加以運用。(6) A multi-mode mobile subscriber station configures a new "Careof Address (CoA)", which can be used by the new access router connected to the new PoA via the transmitted PrRtrAdv.

(7)、(8)、(9)、(10)、(11)該多重模式行動用戶站台及該接取路由器執行一對於FMIPv6的程序。(7), (8), (9), (10), (11) The multi-mode mobile subscriber station and the access router perform a procedure for FMIPv6.

(12)設妥一等於或低於第2層而具一新鏈結的鏈結。(12) Set a link with a new link equal to or lower than the second layer.

(13)透過MIH將此發送至一上層，而由於已完成與該新鏈結之組態，因此可發送L3封包。若此觸發器確經遞送，則一行動管理項目立即地傳送FNA(快速鄰者公告)。一既已接收到該FNA之新接取路由器將所遞送的各封包傳送至該行動用戶站台。(13) This is sent to an upper layer through the MIH, and since the configuration with the new link has been completed, the L3 packet can be sent. If the trigger is delivered, an action management project immediately transmits the FNA (Fast Neighbor Announcement). A new access router that has received the FNA transmits the delivered packets to the mobile subscriber station.

(14)一旦執行過該步驟(13)，即通知該舊PoA的MIH既已設妥與該新PoA的鏈結。(14) Once this step (13) is performed, the MIH of the old PoA is notified that the link to the new PoA has been set.

(15)該接取路由器之MIH觸發既已辨識出已完成與該新PoA之組態的MIH應將資料轉傳到經連接至該新PoA的接取路由器。經此，可精確地知悉一舊接取路由器何時將會轉傳該資料。本發明之影響在於該接取路由器的MIH可藉由因在該舊PoA之MIH與該接取路由器之MIH間的互相通訊而知悉一正確的計時點，以指示資料轉傳處理。而該正確計時點或會不同於本具體實施例所示者。(15) The MIH trigger of the pick-up router has recognized that the MIH that has completed the configuration with the new PoA should forward the data to the pick-up router connected to the new PoA. Through this, it is possible to accurately know when an old access router will forward the data. The effect of the present invention is that the MIH of the access router can know the correct timing point by communicating with each other between the MIH of the old PoA and the MIH of the access router to indicate the data transfer process. And the correct timing point may be different from that shown in this embodiment.

(16)將資料從舊PoA之舊接取路由器轉傳至新PoA的新接取路由器。(16) Transfer the data from the old pick-up router of the old PoA to the new pick-up router of the new PoA.

(17)將一表示該新鏈結既經設妥之遠端觸發器轉傳至該新鏈結之PoA的MIH。此步驟在一類似於步驟(13)者之計時點處進行。在此情況，若其本身辨識出該新鏈結組態，則該新PoA的一鏈結層可直接地通知其新鏈結組態的MIH。(17) A MIH indicating that the new link is forwarded to the PoA of the new link by the set remote trigger. This step is performed at a timing point similar to that of step (13). In this case, if the new link configuration is recognized by itself, a link layer of the new PoA can directly inform the MIH of its new link configuration.

(18)該新PoA的MIH可透過與該接取路由器之MIH的通訊，通知一經連接至該新PoA之接取路由器的MIH因一行動用戶站台之新鏈結的組態而能夠傳送資料。(18) The MIH of the new PoA can communicate with the MIH of the access router to notify that the MIH connected to the access router of the new PoA can transmit data due to the configuration of a new link of the mobile subscriber station.

(19)經通知既已釋放一舊鏈結。可在結束新鏈結的組態之後，藉由一MIH命令以進行此步驟。或另者，可隨即在該新鏈結組態之後進行此步驟，然可維持一預設時間以供與該新鏈結的雙工處理。(19) An old link has been released by notice. This step can be performed with an MIH command after the configuration of the new link is finished. Alternatively, this step can be performed immediately after the new link configuration, but a predetermined time can be maintained for duplex processing with the new link.

(20)由步驟(18)所觸發之新PoA接取路由器可將資料快速地傳送至該行動用戶站台而無延遲。(20) The new PoA access router triggered by step (18) can quickly transmit the data to the mobile subscriber station without delay.

第17圖為一根據本發明之另一較佳具體實施例的流程圖，其中使用FMIPv6(於傳送Link_Going_Up時，一待行遞交之另一型式的介面之PoA位址為已知)。Figure 17 is a flow diagram of another preferred embodiment of the present invention in which FMIPv6 is used (when the Link_Going_Up is transmitted, the PoA address of another type of interface to be submitted is known).

參照第17圖，不同於在使用FMIPv6的情況下於傳送Link_Going_Down的過程中該待行遞交之另一型式介面的PoA位址為已知之情況，本項具體實施例對應於在網路搜尋一新PoA的過程中一新PoA之位址為已知，或是與一新PoA進行鏈結組態程序而在「Link Going Down」內不知此資訊的情況。Referring to FIG. 17, unlike the case where the PoA address of another type of interface to be delivered is known in the process of transmitting Link_Going_Down in the case of using FMIPv6, this embodiment corresponds to searching for a new network. In the process of PoA, the address of a new PoA is known, or the link configuration procedure with a new PoA is not known in the "Link Going Down".

舊PoA之MIH獲通知將以遠端方式組態一鏈結(7)。The MIH of the old PoA is notified that a link (7) will be configured remotely.

並且其餘步驟類似於第16圖中所示之先前具體實施例者。And the remaining steps are similar to those of the previous embodiment shown in FIG.

第18圖為一根據本發明另一較佳具體實施例之流程圖，其中在使用FMIPv6的情況，在組態與一新PoA的鏈結之前，一與一舊PoA之鏈結即已斷連。Figure 18 is a flow chart according to another preferred embodiment of the present invention, wherein in the case of using FMIPv6, the link between an old PoA and the old PoA is disconnected before configuring the link with a new PoA. .

參照第18圖，本項利用FMIPv6之具體實施例的各步驟類似於第16圖中所述之先前具體實施例，並且對應於一步驟(12)之情況，即一接往一舊鏈結之連接在與一新接取路由器完成步驟(1)~(11)之後，即因像是一行動用戶站台遷移等等的此一原因而斷連。Referring to Figure 18, the steps of the specific embodiment of the present invention utilizing FMIPv6 are similar to the previous embodiment described in Figure 16, and correspond to the case of a step (12), that is, to an old link. The connection is disconnected after the completion of steps (1) to (11) with a new access router, that is, due to a mobile station migration or the like.

一旦與一舊鏈結的連接斷連，該行動用戶站台之MIH即自一下層鏈結層而經通知該鏈結斷連(13)。Once disconnected from an old link, the MIH of the mobile subscriber station is notified of the link disconnection from the lower link layer (13).

若一舊PoA管理接往該行動用戶站台之連接，則舊PoA辨識出接往該行動用戶站台之連接既經釋放，並且接著通知一舊接取路由器漏失一特定行動用戶站台的連接(14)。If an old PoA manages the connection to the mobile subscriber station, the old PoA recognizes that the connection to the mobile subscriber station is released, and then notifies an old access router to miss the connection of a specific mobile subscriber station (14) .

所傳送以區分一特定行動用戶站台的資訊為一由該行動用戶站台在一舊PoA處所使用之IP位址或鏈結層位址(即如MAC位址)、一電子序號(ESN)等等。此資訊經包含在待予傳送的「Remote Link Down」之內，而由該舊PoA通知給該舊接取路由器。既已收到此項資訊之接取路由器透過一經事先建構之隧穿通道，藉以遞送一其連接既經釋放之特定行動用戶站台的封包。The information transmitted to distinguish a particular mobile subscriber station is an IP address or link layer address (ie, a MAC address), an electronic serial number (ESN), etc. used by the mobile subscriber station at an old PoA location. . This information is included in the "Remote Link Down" to be transmitted, and the old PoA is notified to the old access router. The receiving router, which has received this information, delivers a packet that connects to the particular mobile subscriber station that has been released through a pre-configured tunneling path.

並且其餘步驟類似於第16圖中所解釋者。And the remaining steps are similar to those explained in Figure 16.

第19圖為一根據本發明另一較佳具體實施例之流程圖，其中在使用FMIPv6的情況下，於設置與該新PoA之鏈結的過程中，在自一MIH而經傳送至一上層的觸發器設妥一鏈結之後，接收到來自一新PoA所快速地轉傳的封包。Figure 19 is a flow chart according to another preferred embodiment of the present invention, wherein in the case of using FMIPv6, in the process of setting up the link with the new PoA, it is transmitted from an MIH to an upper layer. After the trigger is set up, it receives a packet that is quickly transferred from a new PoA.

參照第19圖，本項使用FMIPv6之具體實施例的各項步驟類似於第16圖中所示之先前具體實施例者。在與一新接取路由器完成步驟(1)~(11)之後，即進行一與一新鏈結的組態程序(12)。Referring to Fig. 19, the steps of the specific embodiment of this item using FMIPv6 are similar to those of the previous embodiment shown in Fig. 16. After completing steps (1) to (11) with a new access router, a configuration procedure (12) of one and a new link is performed.

一旦完成與一新PoA的鏈結組態之後，即由一行動用戶站台之鏈結層通知一MIH既已設妥一新鏈結。並且此為經傳送至一含有一行動管理項目之上層(13)。Once the link configuration with a new PoA is completed, the link layer of a mobile subscriber station informs the MIH that a new link has been set. And this is transmitted to an upper layer (13) containing an action management project.

既已收到說明該新鏈結既經設妥的資訊後，該行動管理項目將「Fast Neighbor Advertisement」立即地傳送至該新的接取路由器(17)。After receiving the information indicating that the new link has been set, the action management project immediately transmits the "Fast Neighbor Advertisement" to the new access router (17).

在收到「Fast Neighbor Advertisement」之後，該接取路由器即將一所收封包傳送至一行動用戶站台(18)。After receiving the "Fast Neighbor Advertisement", the pick-up router transmits a packet to a mobile subscriber station (18).

步驟(14)~(16)是有關於一請求訊息，此者經該行動用戶站台/行動站台發送至該來源網路之遞交管理模組，藉此命令將該資料發送至該目標網路的遞交管理模組。在收到該請求訊息之後，該來源網路的遞交管理模組即依如所請求/命令者，將資料遞送至該目標網路的遞交管理模組。最後，在步驟(18)，該目標網路的遞交管理模組/項目將自該來源網路的遞交管理模組所遞送而來之資料傳送至該請求訊息的起點－該行動用戶站台。Steps (14)~(16) are related to a request message, and the user is sent to the delivery management module of the source network via the mobile user station/action station, thereby instructing the data to be sent to the target network. Submit the management module. After receiving the request message, the delivery management module of the source network delivers the data to the delivery management module of the target network as requested/command. Finally, in step (18), the delivery network management module/project of the target network transmits the data delivered from the delivery management module of the source network to the starting point of the request message - the mobile subscriber station.

第20圖為一根據本發明另一較佳具體實施例之流程圖，其中在使用FMIPv6的情況，在設置與一新PoA的鏈結之前，一與一舊PoA之鏈結即已斷連。在第20圖中，在設置與該新PoA之鏈結的過程中，於既已由一自一MIH而傳送至一上層的觸發器設妥一鏈結之後，即收到自一新PoA所快速地轉傳而來的封包。Figure 20 is a flow chart showing another preferred embodiment of the present invention in which, in the case of using FMIPv6, the link to an old PoA is disconnected before the link with a new PoA is set. In Fig. 20, in the process of setting up the link with the new PoA, after a link has been set up from a trigger transmitted from an MIH to an upper layer, it is received from a new PoA. Packets that are quickly passed down.

參照第20圖，在使用FMIPv6的情況下，根據一類似於第16圖中所示之先前具體實施例者的程序，藉由與一新接取路由器執行一程序以建立一新CoA(1)~(6)。Referring to Fig. 20, in the case of using FMIPv6, a new CoA (1) is established by executing a procedure with a new access router according to a procedure similar to that of the previous embodiment shown in Fig. 16. ~(6).

一與一舊PoA之鏈結因一前述原因而經斷連(7)。The link between one and an old PoA is disconnected for one of the foregoing reasons (7).

自一行動用戶站台之鏈結層，透過一MIH通知一上層該鏈結既經斷連(8)。From the link layer of an action user station, an upper layer of the link is notified through an MIH that the link is disconnected (8).

該行動用戶站台啟動一與一新PoA的鏈結設置程序，並且設置一鏈結(9)。The mobile subscriber station initiates a link setup procedure with a new PoA and sets up a link (9).

一旦完成該鏈結組態後，即由該行動用戶站台之一新鏈結層通知一含有一行動管理項目之上層既已完成該鏈結組態(10)。Once the link configuration is completed, the new link layer of one of the mobile subscriber stations informs that the upper layer containing the action management project has completed the link configuration (10).

既已收到該相對應通知之行動管理項目立即地發送「Fast Neighbor Advertisement(Fast Binding Update)」(11)，因而一新接取路由器可藉由建立一與一舊接取路由器之隧穿通道而收到所傳資料(12)、(13)。The action management project that has received the corresponding notification immediately sends the "Fast Neighbor Advertisement (Fast Binding Update)" (11), so that a new access router can establish a tunneling path for the first and the old access routers. Received the transmitted materials (12), (13).

在既已建妥該隧穿通道之後，該舊接取路由器即透過該隧穿通道將一封包傳送至該新接取路由器(14)。After the tunneling channel has been established, the old access router transmits a packet to the new access router (14) through the tunneling channel.

並且，新的接取路由器將封包遞送至該行動用戶站台(15)。And, the new access router delivers the packet to the mobile subscriber station (15).

第21圖為一根據本發明之另一較佳具體實施例的流程圖。Figure 21 is a flow chart showing another preferred embodiment of the present invention.

若一行動用戶站台利用MIPv4或MIPv6作為一行動支援協定，並以一FA－CoA或非狀態型式位址資訊作為轉交位址(CoA)，則在對該新PoA嘗試進行遞交之前，可自一舊PoA處獲得表示可使用一待用於一新PoA處之IP位址而無需改變目前IP位址的資訊。If an active subscriber station uses MIPv4 or MIPv6 as an action support agreement and uses a FA-CoA or non-state type address information as the Care-of Address (CoA), then the new PoA attempt can be submitted before the new PoA attempt is submitted. The old PoA obtains information indicating that an IP address to be used for a new PoA can be used without changing the current IP address.

參照第21圖，一行動用戶站台觸發一對於一舊PoA之「Remote_Link_Going_Up」(6)。Referring to Fig. 21, a mobile subscriber station triggers a "Remote_Link_Going_Up" (6) for an old PoA.

該舊PoA將為以查詢可由該行動用戶站台在一新PoA處使用之IP資訊的IP_Information.request遞送至該新PoA(7)。在此情況下，藉由納入該舊PoA所使用之IP位址以傳送該IP_Information.request。The old PoA will be delivered to the new PoA (7) for IP_Information.request to query IP information that can be used by the mobile subscriber station at a new PoA. In this case, the IP_Information.request is transmitted by including the IP address used by the old PoA.

該新PoA將經納入在該IP_Information.request內之資訊與一該行動用戶站台可透過遞交而使用的IP位址(包含一暫時性IP位址)加以比較。若一舊位址為可用，則該新PoA按照在IP_Information.confirm訊息中將「IP Address Change Notification」欄位設定為1的方式進行回應(無須改變IP位址)。The new PoA compares the information included in the IP_Information.request with an IP address (including a temporary IP address) that the mobile subscriber station can use for delivery. If an old address is available, the new PoA responds by setting the "IP Address Change Notification" field to 1 in the IP_Information.confirm message (without changing the IP address).

舊PoA收到該IP_Information.confirm，並且接著將此轉傳至該行動用戶站台(9)。The old PoA receives the IP_Information.confirm and then forwards this to the mobile subscriber station (9).

在本具體實施例裡是由該新PoA建立並遞送對於該IP_Information.request的回應(IP_Information.confirm)，這是對應於一其中該新PoA藉由傾聽一經連接至該新PoA之路由器或外部代理器的公告來辨識出該資訊之情況。或另者，若並不存在可用位址資訊，則將IP_Information.request遞送至一接取路由器或外部代理器，從而該接取路由器或外部代理器可回應於該IP_Information.request，而將IP_Information.confirm遞送至該新PoA。因此，該新PoA能夠將此遞送至該行動用戶站台。In this embodiment, the new PoA establishes and delivers a response (IP_Information.confirm) for the IP_Information.request, which corresponds to a router or foreign agent in which the new PoA is connected to the new PoA by listening. The announcement of the device to identify the situation of the information. Or, if there is no available address information, the IP_Information.request is delivered to an access router or an external proxy, so that the access router or external proxy can respond to the IP_Information.request and the IP_Information. Confirm is delivered to the new PoA. Therefore, the new PoA can deliver this to the mobile subscriber station.

第22圖為一根據本發明之另一較佳具體實施例的流程圖。Figure 22 is a flow chart showing another preferred embodiment of the present invention.

若一行動用戶站台利用MIPv4或MIPv6作為一行動支援協定，並以一FA－CoA或非狀態型式位址資訊作為轉交位址(CoA)，則在進行自一舊PoA至該新PoA的遞交中，將對於一新PoA配置一FA－CoA或一非狀態型式位址。If an mobile subscriber station uses MIPv4 or MIPv6 as an action support agreement and uses a FA-CoA or non-state type address information as the handover address (CoA), then the submission from the old PoA to the new PoA is performed. A FA-CoA or a non-state type address will be configured for a new PoA.

參照於第22圖，本項具體實施例之程序類似於第10圖中所示之先前具體實施例者。Referring to Figure 22, the procedure of this embodiment is similar to the previous embodiment shown in Figure 10.

然一行動用戶站台是以傳送IP_Information.request而請求在一新PoA處可用的IP位址資訊，而並非是將Remote_Link_Going_Down觸發(轉傳)至一舊PoA(7)。However, the mobile subscriber station requests IP address information available at a new PoA by transmitting IP_Information.request instead of triggering (transferring) Remote_Link_Going_Down to an old PoA (7).

收到該IP_Information.request後，該新PoA比較經包含在該IP_Information.request內之資訊與一在遞交後該行動用戶站台可使用的IP位址(包含一暫時性IP位址)。若一舊位址不可用，並且若是需要改變該IP位址，則該新PoA將含有IP位址資訊之IP_Information.confirm傳送至該行動用戶站台(12~13)。After receiving the IP_Information.request, the new PoA compares the information contained in the IP_Information.request with an IP address (including a temporary IP address) that can be used by the mobile subscriber station after the submission. If an old address is not available, and if the IP address needs to be changed, the new PoA transmits IP_Information.confirm containing the IP address information to the mobile subscriber station (12-13).

在本項具體實施例裡，由於該新PoA未擁有足以回應於該IP_Information.request的資訊，因而藉由將一為請求IP相關資訊之IP_CoA.request(或IP_Information.request而達相同效果)遞送至一經連接至該新PoA的接取路由器或外部代理器以獲得資訊。並且，該行動用戶站台將此項資訊納入在待遞送之IP_Information.confirm。或另者，在藉由傾聽一接取路由器或外部代理器之公告而具有足夠相關於IP之資訊的情況下，該新PoA可將該相對應資訊直接地遞送至該行動用戶站台。In this embodiment, since the new PoA does not have enough information to respond to the IP_Information.request, an IP_CoA.request (or IP_Information.request for the same effect) for requesting IP related information is delivered to Once connected to the new PoA's access router or external agent for information. And, the mobile subscriber station will include this information in the IP_Information.confirm to be delivered. Alternatively, the new PoA may directly deliver the corresponding information to the mobile subscriber station by listening to the announcement of the router or the external agent with sufficient information related to the IP.

第23圖為一根據本發明之另一較佳具體實施例的流程圖。Figure 23 is a flow chart showing another preferred embodiment of the present invention.

若一行動用戶站台利用MIPv4或MIPv6作為一行動支援協定，並以一FA_CoA或非狀態型式位址資訊作為轉交位址(CoA)，則可在嘗試對該新PoA進行遞交之前，按照該行動用戶站台透過一舊PoA將一IP位址資訊請求遞送至一新PoA之方式，來獲得表示該IP位址並未改變之資訊。If an mobile subscriber station uses MIPv4 or MIPv6 as an action support agreement and uses FA_CoA or non-state type address information as the Care-of Address (CoA), the mobile user may be followed before attempting to submit the new PoA. The station transmits an IP address information request to a new PoA through an old PoA to obtain information indicating that the IP address has not changed.

參照第23圖，一行動用戶站台透過一舊PoA將IP_Information.request傳送至一新PoA(6~7)。在遞交之後，該新PoA將經納入在該IP_Information.request內之資訊與一該行動用戶站台可使用的IP位址(包含一暫時性IP位址)加以比較。一舊位址是否為可用。該新PoA藉由將在該IP_Information.confirm訊息內之「IP Address Change notification」欄位設定為1以回應於該舊PoA(無須改變IP位址)(8)。Referring to Fig. 23, a mobile subscriber station transmits IP_Information.request to a new PoA (6-7) through an old PoA. After submission, the new PoA compares the information included in the IP_Information.request with an IP address (including a temporary IP address) available to the mobile subscriber station. Whether an old address is available. The new PoA responds to the old PoA (without changing the IP address) by setting the "IP Address Change notification" field in the IP_Information.confirm message to 1 (8).

收到該IP_Information.confirm訊息後，該舊PoA將此遞送至該行動用戶站台(9)。Upon receipt of the IP_Information.confirm message, the old PoA will deliver this to the mobile subscriber station (9).

在本具體實施例裡，新的PoA建立並對IP_Information.request遞送該回應(IP_Information.confirm)，IP_Information.request係對應於一其中該新PoA藉由傾聽一經連接至該新PoA之路由器或外部代理器的公告以辨識出該資訊之情況。然若並不存在可用的IP位址相關資訊，則會將IP_Information.request遞送至一接取路由器或外部代理器，從而該接取路由器或外部代理器可回應於該IP_Information.request，而將IP_Information.confirm遞送至該新PoA。因此，該新PoA能夠將此遞送至該行動用戶站台。In this embodiment, the new PoA is established and the response is sent to IP_Information.request (IP_Information.confirm), and IP_Information.request corresponds to a router or foreign agent in which the new PoA is connected to the new PoA by listening. The announcement of the device to identify the information. However, if there is no information about the available IP address, the IP_Information.request will be delivered to an access router or external proxy, so that the access router or external proxy can respond to the IP_Information.request and the IP_Information .confirm is delivered to the new PoA. Therefore, the new PoA can deliver this to the mobile subscriber station.

第24圖為一根據本發明之另一較佳具體實施例的流程圖，其中在使用FMIPv6的情況下，可參照於在一新PoA處所使用之位址資訊，而自一舊PoA處獲得能夠使用表示一先前使用之IP位址而無需加以改變的資訊。Figure 24 is a flow chart showing another preferred embodiment of the present invention, wherein in the case of using FMIPv6, reference can be made to the address information used in a new PoA, and the information can be obtained from an old PoA. Use information that represents a previously used IP address without change.

參照第24圖，一行動用戶站台觸發一對於一舊PoA之「Remote_Link_Going_Down」(2)。Referring to Fig. 24, a mobile subscriber station triggers a "Remote_Link_Going_Down" (2) for an old PoA.

該舊PoA將用以查詢(query)可由該行動用戶站台於一新PoA處使用之IP資訊的IP_Information.request遞送至一舊接取路由器(3)。The old PoA will be used to query the IP_Information.request of the IP information that can be used by the mobile subscriber station at a new PoA to an old access router (3).

若該行動用戶站台能夠在該新PoA處使用一先前IP位址而不需在遞交之後改變該先前IP位址，則該舊接取路由器將IP_No_Change傳送至其MIH處(4)。If the mobile subscriber station is able to use a previous IP address at the new PoA without changing the previous IP address after delivery, the old pick-up router transmits IP_No_Change to its MIH (4).

該舊接取路由器之MIH將在IP_Information.confirm訊息內的「IP Address notification」欄位組態為1(無須改變IP位址)，然後將訊息傳送至該舊PoA(5)。The MIH of the old access router will configure the "IP Address notification" field in the IP_Information.confirm message to 1 (without changing the IP address) and then transmit the message to the old PoA (5).

並且該舊PoA將該訊息轉傳至該行動用戶站台(6)。And the old PoA forwards the message to the mobile subscriber station (6).

第25圖為一根據本發明之另一較佳具體實施例的流程圖，其中各步驟類似於第16圖中所示之先前具體實施例者。Figure 25 is a flow diagram of another preferred embodiment of the present invention in which the steps are similar to the prior embodiments shown in Figure 16.

參照第25圖，一行動用戶站台為了請求在一新PoA處可用之IP資訊而傳送IP_Information.request，而非對一舊PoA觸發Remote_Link_Going_Down(2)。Referring to Figure 25, an active subscriber station transmits IP_Information.request in order to request IP information available at a new PoA, instead of triggering Remote_Link_Going_Down(2) on an old PoA.

在收到該IP_Information.request之後，該舊PoA將其轉傳至一舊接取路由器(3)。After receiving the IP_Information.request, the old PoA forwards it to an old access router (3).

該舊接取路由器參照於經包含在該請求訊息內之新接取路由器的位址，將一對於一新接取路由器之代理器公告訊息傳送至該行動用戶站台(4)。The old pick-up router transmits a proxy announcement message for a new pick-up router to the mobile subscriber station (4) with reference to the address of the new pick-up router included in the request message.

第26圖為一根據本發明之另一較佳具體實施例的流程圖，其中各步驟類似於第24圖中所示之先前具體實施例者。Figure 26 is a flow diagram of another preferred embodiment of the present invention in which the steps are similar to the prior embodiments shown in Figure 24.

參照第26圖，一行動用戶站台將IP_Information.request傳送至一舊PoA，而非觸發(轉傳)Remote_Link_Going_Down(2)。Referring to Figure 26, a mobile subscriber station transmits IP_Information.request to an old PoA instead of triggering (transferring) Remote_Link_Going_Down(2).

第27圖為一根據本發明之另一較佳具體實施例的流程圖，其中各步驟類似於第16圖中所示之先前具體實施例者。然而，一舊接取路由器透過一新PoA，藉由與一新接取路由器通訊而獲得一多重模式行動用戶站台之IP位址資訊，並且透過遠端「Link_Up」，將資料自該舊接取路由器轉傳至該新接取路由器。Figure 27 is a flow diagram of another preferred embodiment of the present invention, wherein the steps are similar to the prior embodiments shown in Figure 16. However, an old access router obtains IP address information of a multi-mode mobile subscriber station by communicating with a new access router through a new PoA, and transmits data from the old terminal through the remote "Link_Up". Take the router and transfer it to the new access router.

參照第26圖，吾人可發現到一表示目前所接取之鏈結的狀態正在劣化的資訊。並且，將「Link_Going_Down」觸發器傳送至一MIH以及一需要此項資訊的上層(1)。同時，將表示該鏈結正在劣化之資訊傳送至一目前所接取之PoA的MIH層。可透過一鏈結利用第2層，或是利用第3層或以上，來進行此資訊傳輸作業。該資訊含有一待予新近接取之PoA的位址(接附點)。可事先透過一資訊服務或是透過一鄰者公告以獲得該新PoA的位址。該MIH藉由先前指示對各較低鏈結層進行週期性掃描，藉以獲得對於一可用鏈結層之資訊，並由該上層管理項目指示一各候選鏈結層之列表，藉以維持相對應的資訊(2)。Referring to Fig. 26, we can find a message indicating that the state of the currently taken link is deteriorating. Also, the "Link_Going_Down" trigger is transmitted to an MIH and an upper layer (1) that requires this information. At the same time, the information indicating that the link is degrading is transmitted to the MIH layer of the currently accessed PoA. This information transmission can be performed by using the second layer through a link or by using the third layer or above. The information contains the address (attachment point) of the PoA to be newly accessed. The address of the new PoA can be obtained in advance through an information service or through a neighbor announcement. The MIH periodically scans the lower link layers by the previous indication to obtain information about an available link layer, and indicates a list of candidate link layers by the upper management item, thereby maintaining the corresponding Information (2).

目前所接取之PoA的MIH利用由Link_Going_Down所載荷之新PoA位址，藉由與一新PoA的MIH交換資訊(Inter MIH Query & Response)以獲得該新PoA的網路情況資訊(3)。The MIH of the currently received PoA uses the new PoA address carried by Link_Going_Down to obtain the network information (3) of the new PoA by exchanging information (Inter MIH Query & Response) with the MIH of a new PoA.

一舊PoA的MIH透過該新PoA之MIH，對於該行動用戶站台提出對一IP位址資訊的請求，藉以在對一新接取路由器進行遞交之後加以使用。並且，該舊PoA在透過此訊息交換而通知該新PoA一特定行動用戶站台將啟動一至該新PoA之遞交過程中扮演一角色。因此，該新PoA可向該舊PoA提出請求，以獲得對於該特定行動用戶站台之遞交所必要的額外資訊(4)~(7)。The MIH of an old PoA uses the MIH of the new PoA to request a request for an IP address for the mobile subscriber station, thereby using it after submitting a new access router. Moreover, the old PoA notifies the new PoA that a specific mobile subscriber station will initiate a role in the delivery of the new PoA through the exchange of the message. Thus, the new PoA can make a request to the old PoA to obtain additional information (4)~(7) necessary for the submission of the particular mobile subscriber station.

透過IP資訊回應將位址資訊通知給一舊接取路由器(8)。The address information is notified to an old access router (8) through the IP information response.

一目前所接取之接取路由器接收對於該新PoA之接取路由器的資訊，然後將載荷該資訊之PrRtAdv(代理器路由器公告)傳送至該行動用戶站台(9)。A currently accessed pick-up router receives information about the pick-up router for the new PoA, and then transmits a PrRtAdv (Proxy Router Advertisement) that carries the information to the mobile subscriber station (9).

該多重模式行動用戶站台可透過所收到的PrRtAdv，以組態能夠由一經連接至該新PoA之新接取路由器使用的「New Care of Address(NCoA)」(10)。The multi-mode mobile subscriber station can configure the "New Care of Address (NCoA)" (10) that can be used by a new access router connected to the new PoA via the received PrRtAdv.

該多重模式行動用戶站台及該接取路由器對FMIPv6執行一程序(11)、(12)、(13)、(14)、(15)。The multi-mode mobile subscriber station and the access router perform a procedure (11), (12), (13), (14), (15) on FMIPv6.

設妥一等於或低於第2層而具一新鏈結的鏈結(16)。A link (16) with a new link equal to or lower than the second layer is set.

可透過「Remote_Link_Up」以及一上層，按照將與該新鏈結之鏈結組態通知給該新PoA以及該新接取路由器的MIH之方式，來確保表示該行動用戶站台既已遞交至該新接取路由器之資訊(17)~(19)。It is possible to ensure that the mobile subscriber station has been submitted to the new via "Remote_Link_Up" and an upper layer in accordance with the manner in which the new PoA is notified to the new PoA and the MIH of the new access router. Receive information from the router (17)~(19).

既已收到該遠端「Link_Up」觸發器的新接取路由器MIH藉由對該舊接取路由器發送「Start_Data_Forward」，以指示自該舊接取路由器轉傳資料。若在兩個PoA之間完成該資料傳送，則該新PoA的MIH可藉由將「Start_Data_Forward」傳送至該舊接取路由器之一MIH，以等同地指示轉傳該資料。The new access router MIH that has received the remote "Link_Up" trigger sends a "Start_Data_Forward" to the old access router to indicate that the data is forwarded from the old access router. If the data transfer is completed between the two PoAs, the MIH of the new PoA can be equivalently instructed to transfer the data by transmitting "Start_Data_Forward" to one of the old access routers MIH.

自該舊接取路由器，將一封包轉傳至該新接取路由器(21)。From the old pick-up router, a packet is forwarded to the new access router (21).

此者被通知該舊鏈結既經斷連。可在完成與該新鏈結的組態作業之後，藉由該MIH的一命令執行此程序。此程序可在該新鏈結組態作業之後隨即進行。然本項程序可暫緩一預設時間，以用於具有該新鏈結的雙工處理(22)。This person was notified that the old link was disconnected. This procedure can be performed by a command of the MIH after the configuration job with the new link is completed. This program can be performed immediately after the new link configuration job. However, the program can suspend a preset time for duplex processing (22) with the new link.

獲悉既已完成該行動用戶站台與該新PoA之間的鏈結，則該新PoA的接取路由器將所轉傳之資料在未延遲下立即地傳送至該多重模式行動用戶站台(23)。Upon learning that the link between the mobile subscriber station and the new PoA has been completed, the new PoA's access router transmits the transferred data to the multi-mode mobile subscriber station (23) without delay.

第28圖為一根據本發明之另一較佳具體實施例的流程圖，其中顯示一利用一由本發明所提議之命令的MIH層級遞交情境。Figure 28 is a flow diagram showing another embodiment of the present invention in which an MIH level submission scenario utilizing a command proposed by the present invention is shown.

參照於第28圖，一行動用戶站台的舊鏈結發現一目前所接取之鏈結的狀態正在劣化，並接著將「Link_Going_Down.indication」觸發器傳送至一MIH以及一需要本項資訊的上層(1)。Referring to Figure 28, the old link of a mobile subscriber station finds that the state of the currently accessed link is deteriorating, and then transmits the "Link_Going_Down.indication" trigger to an MIH and an upper layer that requires this information. (1).

該上層透過MIH_Scan命令將一可用鏈結掃描指示至該MIH。The upper layer instructs an available link scan to the MIH via the MIH_Scan command.

一可用於遞交之新鏈結透過「Link_Available」通知其鏈結可用於一遞交(3)。A new link that can be used for delivery can be notified by a "Link_Available" that its link can be used for a delivery (3).

該行動用戶站台的MIH藉由將「MIH_Handover_Initiate.request」發送至一舊PoA之MIH的方式，透過一掃描處理來傳送其意圖以遞交至一潛在地可用於遞交之鏈結(4)。The MIH of the mobile subscriber station transmits its intent through a scanning process to deliver a link (4) potentially available for delivery by transmitting "MIH_Handover_Initiate.request" to the MIH of an old PoA.

該舊PoA的MIH透過Inter_MIH.query以查詢該新PoA的MIH關於一所提議之新鏈結的資源是否確為足夠，並且同時地通知該新PoA的MIH該行動用戶站台將要遞交至一相對應PoA(5)。The MIH of the old PoA uses Inter_MIH.query to query whether the MIH of the new PoA is sufficient for the resource of a proposed new link, and simultaneously informs the MIH of the new PoA that the mobile subscriber station is to be submitted to a corresponding one. PoA (5).

該新PoA的MIH經由Inter_MIH.response通知該舊PoA的MIH透過該Inter_MIH.query所請求的結果(6)。The MIH of the new PoA notifies the MIH of the old PoA via the Inter_MIH.response the result requested by the Inter_MIH.query (6).

該舊PoA根據透過該Inter_MIH.query及該Inter_MIH.response所獲得的資訊，通知該行動用戶站台一可用於遞交的PoA。在本例中，該舊PoA可選擇以表示一不同於由該行動用戶站台所請求之鏈結的鏈結(7)。The old PoA notifies the mobile subscriber station of a PoA available for delivery based on the information obtained through the Inter_MIH.query and the Inter_MIH.response. In this example, the old PoA can be selected to represent a different link (7) than the one requested by the mobile subscriber station.

為了事先獲得對於所選定鏈結的IP位址資訊，該行動用戶站台將「IP_Information.request」傳送至該新PoA的MIH。或另者，該既已透過該「Inter_MIH.response」而獲得所選定鏈結之舊PoA的MIH可藉由將「IP_Information.request」直接地傳送至該新PoA的MIH，以請求該行動用戶站台之一新IP位址(7)。In order to obtain IP address information for the selected link in advance, the mobile subscriber station transmits "IP_Information.request" to the MIH of the new PoA. Or alternatively, the MIH of the old PoA that has obtained the selected link through the "Inter_MIH.response" can request the mobile subscriber station by directly transmitting "IP_Information.request" to the MIH of the new PoA. One of the new IP addresses (7).

該PoA之MIH請求並且自一經連接之接取路由器獲得該行動用戶站台的一新IP位址(8)~(12)。The PoA's MIH request and a new IP address (8)~(12) of the mobile subscriber station is obtained from the connected access router.

該新PoA的MIH透過「IP_Information.response」而將所獲之IP位址傳送至該行動用戶站台(13)。The MIH of the new PoA transmits the obtained IP address to the mobile subscriber station (13) via "IP_Information.response".

該行動用戶站台可藉由將「MIH_Handover_Commit.request」傳送至該舊PoA的MIH以通知該舊PoA的MIH(14)。The mobile subscriber station can notify the MIH of the old PoA by transmitting "MIH_Handover_Commit.request" to the MIH of the old PoA (14).

該舊PoA回應於該「MIH_Handover_Commit.request」而將「MIH_Handover_Commit.response」傳送至該行動用戶站台(15)。The old PoA transmits "MIH_Handover_Commit.response" to the mobile subscriber station (15) in response to the "MIH_Handover_Commit.request".

該行動用戶站台之新鏈結藉由將「Link_Up」傳送至一上層，並且按遠端方式將「Link_Up」傳送至該新PoA的MIH，以聲明該行動用戶站台既已完成新鏈結組態作業(16)。The new link of the mobile subscriber station transmits the "Link_Up" to an upper layer and transmits the "Link_Up" to the MIH of the new PoA in a remote manner to declare that the mobile subscriber station has completed the new link configuration. Homework (16).

該新PoA的MIH藉由將「Start_Data_Forward」傳送至該舊接取路由器，以請求將資料自該舊PoA轉傳至該新PoA。因而可自該舊接取路由器將一封包轉傳至該新接取路由器(17)、(18)。或另者，可按照該新PoA向該新接取路由器提出對於資料轉傳之請求，並且該新接取路由器向該舊接取路由器提出請求的方式以達到該資料轉傳之請求。若於各PoA之間達成該資料轉傳處理，則該資料轉傳處理以按照該新PoA將「Start_Data_Forward」遞送至該舊PoA，而無需向該接取路由器提出請求的方式來轉傳資料。The MIH of the new PoA requests to transfer data from the old PoA to the new PoA by transmitting "Start_Data_Forward" to the old access router. Thus, a packet can be forwarded from the old access router to the new access routers (17), (18). Alternatively, the new PoA may be requested to forward the data to the new access router, and the new access router may request the old access router to reach the request for the data transfer. If the data transfer process is completed between the PoAs, the data transfer process is performed to deliver "Start_Data_Forward" to the old PoA according to the new PoA, without transferring the data to the pick-up router.

第29圖為一根據本發明之進一步較佳具體實施例的流程圖，其中利用預先設置一在遞交之後所待使用的IP位址，透過一由本發明所提議之資訊伺服器而事先既已組態一IP位址。Figure 29 is a flow chart showing a further preferred embodiment of the present invention in which an IP address to be used after delivery is set in advance, and is previously set by an information server proposed by the present invention. State an IP address.

參照於第29圖，一行動用戶站台的舊/來源/先前鏈結獲得表示一目前所接取之鏈結正在劣化的狀態之資訊，而接著將「Link_Going_Down.indication」傳送至一MIH及一需要此項資訊的上層。然後將該項資訊遞送至一舊PoA。在此情況下，可將一待予新近接取之PoA的位址(MAC位址或IP位址)納入該項待行遞送的資訊內(1)。Referring to Figure 29, the old/source/previous link of a mobile subscriber station obtains information indicating that the currently accessed link is degrading, and then transmits "Link_Going_Down.indication" to an MIH and a need. The upper level of this information. The information is then delivered to an old PoA. In this case, the address (MAC address or IP address) of the PoA to be newly received may be included in the information to be delivered (1).

知悉該項表示該行動用戶站台之鏈結正在劣化，並且該行動用戶站台將會移至之PoA的位址之資訊，該舊PoA即向一資訊伺服器提出對有相關於該行動用戶站台在該新PoA處可使用之IP位址組態的資訊之請求(2)。換言之，該行動用戶站台/行動終端建立一網路遞交模組(即如MIH)，此係為以將來自於至少一與同質或異質網路之至少一者的網路介面模組(即如MAC)相關之資訊斂聚為統一化的呈現方式。之後，該行動用戶站台將一請求一網際網路協定位址相關訊息之查詢訊息，自該行動用戶站台/終端發送至一網路的資訊伺服器。Knowing that the link indicating that the mobile subscriber station is degrading, and the mobile subscriber station will move to the information of the PoA address, the old PoA submits an information to the information server that is relevant to the mobile subscriber station. A request for information configured by the IP address at the new PoA (2). In other words, the mobile subscriber station/mobile terminal establishes a network delivery module (ie, MIH), which is a network interface module that will come from at least one of the homogenous or heterogeneous networks (ie, MAC) related information is gathered into a unified presentation. Thereafter, the mobile subscriber station sends an inquiry message requesting an Internet Protocol address related message from the mobile subscriber station/terminal to an information server of the network.

該資訊伺服器將該項相關於該IP位址組態之資訊，遞送至提出該請求的PoA(3)。將該項相關於該IP位址組態之資訊中繼傳送至該行動用戶站台，以待轉傳至該行動用戶站台的上層(3)。換言之，該行動用戶站台自該網路之資訊伺服器收到一回應於該查詢請求訊息之回應訊息，而此者含有一目標網路的網際網路協定位址資訊。The information server delivers the information related to the IP address configuration to the PoA (3) that made the request. The information related to the configuration of the IP address is relayed to the mobile subscriber station for transmission to the upper layer (3) of the mobile subscriber station. In other words, the mobile subscriber station receives a response message from the information server of the network in response to the inquiry request message, and the user includes an internet protocol address information of the target network.

或另者，另一種透過一資訊伺服器接收IP位址資訊的方法，則為對應於一種其中一行動用戶站台之MIH向一資訊伺服器直接地請求並接收資訊的方法。Alternatively, another method of receiving IP address information through an information server is a method for directly requesting and receiving information from an MIH corresponding to one of the mobile subscriber stations to an information server.

該行動用戶站台向該資訊伺服器提出一對於IP位址相關之資訊的請求(4)。The mobile subscriber station submits a request for information related to the IP address to the information server (4).

該資訊伺服器將在遞交之後於一新PoA處可使用的IP位址相關資訊遞送至提出請求的行動用戶站台。然後將該項資訊遞送至該行動用戶站台的上層(5)。The information server delivers the IP address related information available at a new PoA to the requesting mobile subscriber station after delivery. This information is then delivered to the upper layer (5) of the mobile subscriber station.

該行動用戶站台的上層，亦即一關聯於該IP位址組態的層級，即如一IP層或一行動協定管理層，在IPv6的情況下為傳送「Router Solicitation」，或在「Mobile IPv4」的情況下為傳送「Agent Solicitation」，以於進行遞交之前先組態一IP位址。藉由單一廣播或隧穿傳送至一目前PoA之接取路由器或一外部代理器，將該「Router Solicitation」或「Agent Solicitation」遞送至一在該新PoA處所使用的位址路由器或外部代理器(6)。The upper layer of the mobile subscriber station, that is, a hierarchy associated with the IP address configuration, that is, an IP layer or an action agreement management layer, in the case of IPv6, "Router Solicitation" or "Mobile IPv4" In the case of the transfer of "Agent Solicitation", an IP address is configured before the delivery. Delivering "Router Solicitation" or "Agent Solicitation" to an address router or external proxy used at the new PoA by single broadcast or tunneling to a current PoA access router or an external proxy (6).

既已收到該行動用戶站台之「Router Solicitation」或「Agent Solicitation」的接取路由器或外部代理器藉由單一廣播或隧穿傳送而將一相對應回應傳送至該行動用戶站台(7)。An access router or external agent that has received the "Router Solicitation" or "Agent Solicitation" of the mobile subscriber station transmits a corresponding response to the mobile subscriber station (7) by a single broadcast or tunneling transmission.

該行動用戶站台組態一與一新POA的鏈結(9)。The mobile subscriber station configures a link to a new POA (9).

透過該行動用戶站台的MIH，通知該上層既已設妥一新鏈結(10)。Through the MIH of the mobile subscriber station, it is notified that the upper layer has already set up a new link (10).

由於因設妥一新鏈結之故而可傳送一IP層封包，因此該上層執行一與一本家代理器的註冊程序(11)、(12)。Since an IP layer packet can be transmitted due to the setting of a new link, the upper layer executes registration procedures (11), (12) of one and one home agent.

而另一種的IP位址組態方法即為一種方法，其中一行動用戶站台透過一資訊伺服器獲得一新PoA的DHCP伺服器位址，並且在一行動用戶站台開始遞交之前，先透過一舊PoA藉由與一DHCP伺服器之通訊配置一待由該新PoA所使用的IP位址。Another method of IP address configuration is a method in which a mobile subscriber station obtains a DHCP server address of a new PoA through an information server, and transmits an old server before the mobile subscriber station begins to submit. The PoA configures an IP address to be used by the new PoA by communicating with a DHCP server.

從而，在該IP位址重新設置方法裡，當在各異質網路之間進行遞交時，可藉由透過各MIH間之通訊而讓第3層(L3)能夠辨識第2層(L2)遞交，即能避免傳送不必要的訊息，並且縮短進行遞交的所耗時間。Therefore, in the IP address resetting method, when the delivery is made between the heterogeneous networks, the layer 3 (L3) can recognize the layer 2 (L2) submission by communicating between the MIHs. , which avoids sending unnecessary messages and shortens the time it takes to submit.
