Description

移动网络管理方法和移动路由器技术领域 Mobile network management method and mobile router

本发明涉及通信技术领域，尤其涉及移动网络管理方法和移动路由器。背景技术 The present invention relates to the field of communications technologies, and in particular, to a mobile network management method and a mobile router. Background technique

在 Internet中 , 主要使用 IP地址和 DNS域名进行主机标识 , 由于网络用户的不断增多，网络应用种类的不断丰富，网络规模不断扩大，导致 IP地址与 DNS域名数量不能够满足网络用户的需要。为了解决 IP地址和 DNS域名数量不足的问题，引入一个基于 HIP(Host Identity Protocol, 主机标识协议) 的命名空间 HIN(Host Identity Namespace , 主机标识命名空间）。 In the Internet, host IDs are mainly used for IP addresses and DNS domain names. Due to the increasing number of network users, the variety of network applications is increasing, and the network scale is expanding. As a result, the number of IP addresses and DNS domain names cannot meet the needs of network users. To solve the problem of insufficient number of IP addresses and DNS domain names, a host identity name space (HIN) based on the HIP (Host Identity Protocol) is introduced.

在 TCP/IP协议的基础上， HIP协议在传输层和网络层之间增加了主机标识层，并且在主机标识层设置一个用来标识主机的 HI ( Host Identity, 主机标识），使得 IP地址不再用于标识主机，而仅用于标识主机的位置，解决了 IP 和 DNS命名空间不足的问题。 On the basis of the TCP/IP protocol, the HIP protocol adds a host identification layer between the transport layer and the network layer, and sets a HI (Host Identity) for identifying the host at the host identification layer, so that the IP address is not It is used to identify the host and is only used to identify the location of the host, which solves the problem of insufficient IP and DNS namespaces.

在现实环境中，存在着许多移动网络，如，移动的列车及列车上的控制 ***就可以构成一个移动网络，列车的控制***中包含多种可以联网的传感设备，这些传感设备作为列车上的移动节点，用于将列车当前运行状态实时传给调度中心进行处理。 In the real world, there are many mobile networks. For example, the mobile train and the control system on the train can form a mobile network. The train control system contains a variety of sensing devices that can be networked. These sensing devices act as trains. The mobile node is used to transmit the current running state of the train to the dispatch center for processing in real time.

移动网络中通常包含一个 MR ( Mobile Router, 移动路由器）， MR中存有 <HIT— MR,Locator— MR> 、 <HIT_MN,Locator_MN> 、和 <HIT_FN,Locator_FN>„ 其中， <HIT— MR,Locator— ^11 >为 MR的识别信息， <HIT— MN,Locator— MN>为移动网络内所有向 MR注册过的移动节点的识别信息， <HIT— FN,Locator— FN>为移动网络内归属节点的识别信息。具体的， HIT 为用于标识 MR、或 MN ( Mobile Node, 移动节点）、或 FN ( Fixed Node , 归属节点 )的主机标识信息， HIT可识别 MR、或 MN、或 FN的身份，与 MR、或 MN、或 FN的位置无关； Locator— MR为 MR的地址信息； Locator— MN为 MN, 的地址信息； Locator FN为 FN的地址信息。移动网络中通常还包含移动网路所属 RVS ( Rendezvous Service , 汇聚服务器）、和与移动网络内的移动节点或归属节点进行通信的对端主机， RVS、对端主机中存储有<¾1丁— MR,Locator— MR>、 <HIT_MN, Locator— MR>、和 <HIT_FN, Locator— MR>。当移动网络发生移动时，由于移动网络位置的变化， MR的 Locator— MR会随之发生变化，为了保证移动网络移动后与对端主机之间通信的建立，也为了保证移动网络中已经建立的通信不会中断， MN需要更新 RVS、对端主机内存储的<¾1丁— MR,Locator— MR>、 <HIT_MN, Locator— MR>、和<¾1丁— FN, Locator— ^11 >中的信息 , 在移动网络内节点较多时 , 需要大量位置更新消息在 MR与 RVS、对端主机之间进行传输。 The mobile network usually includes an MR (Mobile Router), and the MR contains <HIT-MR, Locator_MR>, <HIT_MN, Locator_MN>, and <HIT_FN, Locator_FN> „ where <HIT-MR, Locator – ^11 > is the identification information of the MR, <HIT_MN, Locator_MN> is the identification information of all the mobile nodes registered in the MR in the mobile network, <HIT_FN, Locator_FN> is the home node in the mobile network Specifically, the HIT is the host identification information used to identify the MR, or the MN (Mobile Node), or the FN (Fixed Node), and the HIT can identify the identity of the MR, or the MN, or the FN. Independent of the position of MR, or MN, or FN; Locator - MR is the address information of MR; Locator - MN is the address information of MN; Locator FN is the address information of FN. The mobile network usually includes the RVS (Rendezvous Service) to which the mobile network belongs, and the peer host that communicates with the mobile node or the home node in the mobile network. The RVS and the peer host store the <3⁄41丁-MR. , Locator — MR>, <HIT_MN, Locator — MR>, and <HIT_FN, Locator — MR>. When the mobile network moves, the Locator-MR of the MR changes with the change of the location of the mobile network. In order to ensure the establishment of communication between the mobile network and the peer host, the mobile network has been established. The communication will not be interrupted. The MN needs to update the information in the RVS, the <3⁄41 D-MR, Locator-MR>, <HIT_MN, Locator-MR>, and <3⁄41-FN, Locator-^11> stored in the peer host. When there are many nodes in the mobile network, a large number of location update messages are required to be transmitted between the MR and the RVS and the peer host.

现有技术中，通过以下方式对移动网络进行管理，包括： In the prior art, the mobile network is managed in the following manner, including:

移动网络发生移动后， MR 的位置随之发生变化，进而使 MR 的 Locator— MR信息发生变化。 MR向所有存储其 Locator— MR信息的相关实体发送 Update消息，更新相关实体中存储的 Locator— MR信息，相关实体包括：移动节点所属服务器 RVS— MN、 RVS和对端主机。 After the mobile network moves, the position of the MR changes, which in turn changes the MR Locator-MR information. The MR sends an Update message to all related entities storing its Locator_MR information, and updates the Locator_MR information stored in the related entity. The related entities include: the server to which the mobile node belongs RVS-MN, RVS, and the peer host.

在实现上述移动网络管理方法的过程中，发明人发现现有技术中至少存在如下问题：当移动网络中的 MN、 FN较多，且 MN、 FN与对端主机建立大量会话时，移动网络发生移动后，为了使移动网络中的 MN和 FN与对端主机之间的通信保持不中断，移动网络的 MR 需要向对端主机更新大量 Locator— MR信息，过多的位置更新消息会占用大量的网络资源，从而影响网络的性能。 In the process of implementing the foregoing mobile network management method, the inventor has found that at least the following problems exist in the prior art: When there are many MNs and FNs in the mobile network, and the MN and the FN establish a large number of sessions with the peer host, the mobile network occurs. After the move, in order to keep the communication between the MN and the FN in the mobile network and the peer host uninterrupted, the MR of the mobile network needs to update a large amount of Locator-MR information to the peer host, and excessive location update messages will occupy a large amount of Network resources, which affect the performance of the network.

Information, so that the egress gateway sends a communication request message of the received peer host to the MR.

MR向出口网关发送的第四注册请求消息时， MR向第四注册请求消息中添加移动网络标识参数 NET— IDENTITY, 参数 NET— IDENTITY格式如图 4 所示。 When the MR sends the fourth registration request message to the egress gateway, the MR adds a mobile network identification parameter NET_IDENTITY to the fourth registration request message, and the parameter NET_IDENTITY format is as shown in FIG.

第四注册请求消息中携带有 Locator— MR, 即为 MR的第一地址信息，出口网关将 MR的主机标识信息和第一地址信息存入出口网关映射信息表中。 The fourth registration request message carries the Locator_MR, which is the first address information of the MR, and the egress gateway stores the host identification information and the first address information of the MR into the egress gateway mapping information table.

206、出口网关确定其收到的第四注册请求消息是否由移动网络发送的。如果在 MR 向出口网关发送的第四注册请求消息中携带参数 206. The egress gateway determines whether the fourth registration request message it receives is sent by the mobile network. If the parameter is carried in the fourth registration request message sent by the MR to the egress gateway

NET— IDENTITY, 就说明这个第四注册请求消息是从移动网络发送来的，如果第四注册请求消息中未携带参数 NET— IDENTITY, 说明这个第四注册请求消息不是从移动网络发送来的。 NET-IDENTITY, indicating that the fourth registration request message is sent from the mobile network. If the fourth registration request message does not carry the parameter NET_IDENTITY, the fourth registration request is indicated. The message was not sent from the mobile network.

具体的，出口网关检测进入网络的 MR发来的第四注册请求消息中是否携带有参数 NET— IDENTITY。若出口网关检测到进入网络的 MR发来的第四注册请求消息中携带参数 NET— IDENTITY, 则执行步骤 207, 否则，执行步骤 208。 Specifically, the egress gateway detects whether the parameter NET_IDENTITY is carried in the fourth registration request message sent by the MR entering the network. If the egress gateway detects that the fourth registration request message sent by the MR entering the network carries the parameter NET_IDENTITY, step 207 is performed; otherwise, step 208 is performed.

207、 MR接收出口网关发送的携带出口网关主机识别信息和出口网关地址信息的第二消息，第二消息是出口网关在确定了其收到的第四注册请求消息是由移动网络发送的之后发送的。 207. The MR receives a second message that is sent by the egress gateway and carries the egress gateway host identification information and the egress gateway address information. The second message is that the egress gateway sends after the fourth registration request message that is received by the egress network is sent by the mobile network. of.

当出口网关检测到进入网络的 MR发来的第四注册请求消息中携带参数 NET— IDENTITY时，出口网关将携带有自身的地址信息，即 Locator的应答消息回复给 MR, 记为第二消息， MR存储出口网关的 Locator, 以便移动网络移动后， MR 向出口网关发送位置更新消息。出口网关检测消息中参数 NET— IDENTITY和回复 MR应答消息的过程如图 5所示。若出口网关在第四注册请求消息中未检测到参数 NET— IDENTITY , 那么说明第四注册请求消息来自于非移动网络，非移动网络的 MR第一地址信息不会改变， MR无需向出口网关更新第一地址信息，这样出口网关就不需要将携带有自身的 Locator消息回复给 MR。 When the egress gateway detects that the fourth registration request message sent by the MR that enters the network carries the parameter NET_IDENTITY, the egress gateway will carry its own address information, that is, the response message of the Locator is returned to the MR, and is recorded as the second message. The MR stores the Locator of the egress gateway, so that after the mobile network moves, the MR sends a location update message to the egress gateway. The process of the parameter NET_IDENTITY and replying to the MR response message in the egress gateway detection message is shown in Figure 5. If the egress gateway does not detect the parameter NET_IDENTITY in the fourth registration request message, then the fourth registration request message is from the non-mobile network, and the MR first address information of the non-mobile network does not change, and the MR does not need to update to the egress gateway. The first address information, so that the egress gateway does not need to reply to the MR with the Locator message carrying itself.

208、在移动网络发生移动后， MR向出口网关发送第一消息，第一消息中携带移动路由器的第二地址信息，以便于出口网关存储第一地址信息和第二地址信息的对应关系。 208. After the mobile network moves, the MR sends a first message to the egress gateway, where the first message carries the second address information of the mobile router, so that the egress gateway stores the correspondence between the first address information and the second address information.

当移动网络移动后， MR的第一地址信息 Locator— MR随之发生改变，为了减少移动网络移动后，移动网络中 MN、和 FN向对端主机发送位置更新消息的数量，将 MR位置变换前后的地址信息 Locator— MR—同存入出口网关映射信息表中。当出口网关接收到对端主机发来的通信请求消息时，出口网关查询出口网关映射信息表，如果通信请求消息携带的 Locator— MR已经发生过变化，即通信请求消息携带的 Locator— MR在出口网关映射信息表中已为变换前的 Locator— MR, 则出口网关将通信请求消息的目的地址替换为变换后的 Locator— MR, 并将通信请求消息发送至变换后的 Locator— MR的 MR。当一终端与另一终端进行通信时，首先，一终端向另一终端发送通信请求消息，通信请求消息中携带有终端需要发送的信息、和目的节点的主机标识信息。其中目的节点包括 MN、和 FN。 After the mobile network moves, the first address information of the MR Locator_MR changes accordingly. In order to reduce the number of location update messages sent by the MN and the FN to the opposite host in the mobile network after the mobile network moves, the MR position is changed before and after. The address information Locator_MR is stored in the egress gateway mapping information table. When the egress gateway receives the communication request message sent by the peer host, the egress gateway queries the egress gateway mapping information table. If the Locator_MR carried in the communication request message has changed, that is, the Locator_MR carried in the communication request message is on the exit. In the gateway mapping information table, which is already the Locator_MR before the transformation, the egress gateway replaces the destination address of the communication request message with the transformed address. Locator - MR, and sends a communication request message to the MR of the transformed Locator - MR. When a terminal communicates with another terminal, first, a terminal sends a communication request message to another terminal, where the communication request message carries information that the terminal needs to send and host identification information of the destination node. The destination node includes MN, and FN.

具体的，当移动网络移动后， MR的 Locator— MR随之发生改变，此时， MR将携带有变化后的第二地址信息 Locator— MR— new的第一消息发送到出口网关，出口网关将变化前和变化后的地址信息存入出口网关映射信息表中，记为<1^0。&1；01"— MR— old, Locator— MR— new>。其中， Locator— MR— old为第一地址信息； Locator— MR— new为第二地址信息。 Specifically, after the mobile network moves, the Locator_MR of the MR changes accordingly. At this time, the MR sends a first message carrying the changed second address information Locator_MR_new to the egress gateway, and the egress gateway will The address information before and after the change is stored in the egress gateway mapping information table, and is recorded as <1^0. &1; 01" - MR - old, Locator - MR - new> where Locator - MR - old is the first address information; Locator - MR - new is the second address information.

209、 MR将 MN的第一识别信息中的地址信息替换为 RVS的地址信息，得到第四识别信息。 209. The MR replaces the address information in the first identification information of the MN with the address information of the RVS, to obtain the fourth identification information.

在移动网络发生移动后，由于 RVS 的地址信息不发生变化，即 Locator— RVS未变化，为了减少移动网络移动后， MN向 MN所属的 RVS— MN 发送位置更新消息的数量， RVS— MN为 MN所属的服务器，因此， MR将 MN 的第一识别信息中的 Locator— MN替换为 Locator— RVS, 获得第四识别信息，记为<¾1丁— MN , Locator— RVS>。随后 MR 将第四识别信息发送至对应的 RVS— MN。此时， MR中仍会存有第一识别信息。 After the mobile network moves, since the address information of the RVS does not change, that is, the Locator-RVS does not change, in order to reduce the mobile network movement, the MN sends the number of location update messages to the RVS-MN to which the MN belongs, and the RVS_MN is the MN. The associated server, therefore, the MR replaces the Locator_MN in the first identification information of the MN with the Locator_RSS, and obtains the fourth identification information, which is denoted as <3⁄41丁-MN, Locator_RVS>. The MR then sends the fourth identification information to the corresponding RVS-MN. At this time, the first identification information still exists in the MR.

210、 MR向 RVS— MN发送第五注册请求消息 , 第五注册消息中包含第四识别信息，以便对端主机在向 MN发送通信请求消息时，从第四识别信息中获取移动网络所属服务器的地址信息，从获取到的地址信息的移动网络所属服务器中获取第二识别信息，根据通信请求消息中的移动节点的主机标识信息，从第二识别信息中获取移动路由器的主机标识信息，根据移动路由器的主机标识信息，从第三识别信息中获取移动路由器的第一地址信息。 210. The MR sends a fifth registration request message to the RVS-MN, where the fifth registration message includes the fourth identification information, so that the peer host obtains the server to which the mobile network belongs from the fourth identification information when sending the communication request message to the MN. The address information, the second identification information is obtained from the server of the mobile network to which the obtained address information is obtained, and the host identification information of the mobile router is obtained from the second identification information according to the host identification information of the mobile node in the communication request message, according to the mobile The host identification information of the router obtains the first address information of the mobile router from the third identification information.

在 Internet中，包含 DNS ( Domain Name System, 域名***）， DNS中主要存储了该网络中所有 MN、和 FN 的主机标识信息和地址信息，以及各个 MN对应的 RVS— MN的地址信息。 In the Internet, the DNS (Domain Name System) is included. The DNS mainly stores the host identification information and address information of all MNs and FNs in the network, and the address information of the RVS-MN corresponding to each MN.

移动节点 MN初始接入移动网络时，需要通过向 RVS— MN发送第五注册请求消息进行注册，第五注册请求消息中包含第四识别信息。 RVS— MN将第五注册请求消息中的第四识别信息存入 RVS— MN映射信息表，以便在对端主机与移动网络内的 MN之间进行通信时 , RVS— MN可以获得 RVS的地址信息 , 再通过 RVS 获得 MR 的第一地址信息。第四识别信息记为<¾1丁— MN , Locator— RVS>。 When the mobile node MN initially accesses the mobile network, it needs to send a fifth registration to the RVS-MN. The request message is registered, and the fifth registration request message includes the fourth identification information. The RVS-MN stores the fourth identification information in the fifth registration request message into the RVS-MN mapping information table, so that the RVS-MN can obtain the address information of the RVS when the peer host communicates with the MN in the mobile network. Then obtain the first address information of the MR through RVS. The fourth identification information is recorded as <3⁄41丁-MN, Locator-RVS>.

具体的，当对端主机与移动网络内的 MN开始通信，首先对端主机查询 DNS, 得到目的 MN对应的 RVS— MN的地址信息，对端主机将通信请求消息发送至该地址对应的 RVS— MN。 RVS— MN在接收到对端主机发来的通信请求消息后， RVS— MN 通过 RVS— MN 映射信息表获得 RVS 的地址信息，即 Locator— RVS , RVS— MN将通信请求消息发送至该地址的 RVS。消息到达 RVS , 执行步骤 204中 "二次查询"。具体流程如图 6所示。 Specifically, when the peer host starts to communicate with the MN in the mobile network, the peer host first queries the DNS to obtain the address information of the RVS-MN corresponding to the destination MN, and the peer host sends a communication request message to the RVS corresponding to the address. MN. RVS—The MN receives the communication request message from the peer host, and the RVS-MN obtains the address information of the RVS through the RVS-MN mapping information table, that is, Locator-RVS, and the RVS-MN sends a communication request message to the address. RVS. The message arrives at RVS and performs a "secondary query" in step 204. The specific process is shown in Figure 6.

本实施例提供移动网络管理方法， MR将接收到的 MN、或 FN的第一识别信息中的地址信息替换为 MR的主机标识信息，得到用于标识 MN和 FN 的第二识别信息， MR向 RVS发送第二识别信息，以及 MR的主机标识信息和 MR的第一地址信息。 The embodiment provides a mobile network management method, in which the MR replaces the address information in the first identification information of the received MN or FN with the host identification information of the MR, and obtains second identification information for identifying the MN and the FN. The RVS transmits the second identification information, and the host identification information of the MR and the first address information of the MR.

综上， RVS映射信息表中存储<¾1丁— MN, HIT— MR>、 <HIT— FN, HIT— MR> 和<¾1丁— MR, Locator— MR>, HIT— MN、 HIT— MR、 HIT— FN分别是 MN、 MR、和 FN的主机标识信息，与移动网络的位置无关，移动网络发生移动后， MR 的 Locator— MR信息随之改变，但是 HIT— MN、 HIT— MR、 HIT— FN均不变。因此，在移动网络移动过程中，在 RVS 映射信息表中 MN 的注册信息 <HIT_MN, HIT— MR>、 FN的注册信息<¾1丁— FN, HIT— ^11 >均不需要更改，只需要 MR通过向 RVS发送位置更新消息来修改 RVS映射信息表中 MR的注册信息<¾1丁— MR , Locator— MR>。 MN、和 FN 向 RVS、 MN 所属服务器 RVS— MN、对端主机的出口网关的注册过程如图 Ί所示。 In summary, the RVS mapping information table stores <3⁄41丁-MN, HIT-MR>, <HIT-FN, HIT-MR> and <3⁄41丁-MR, Locator-MR>, HIT-MN, HIT-MR, HIT – FN is the host identification information of MN, MR, and FN, respectively. It is independent of the location of the mobile network. After the mobile network moves, the Locator-MR information of MR changes, but HIT—MN, HIT—MR, HIT—FN Not constant. Therefore, during the mobile network movement process, the registration information of the MN <HIT_MN, HIT-MR>, FN registration information <3⁄41丁-FN, HIT-^11> in the RVS mapping information table do not need to be changed, only MR is required. Modify the note of the MR in the RVS mapping information table by sending a location update message to the RVS Book information <3⁄41丁—MR, Locator—MR>. The registration process of the MN, and the FN to the RVS, the server RVS-MN to which the MN belongs, and the egress gateway of the peer host are as shown in FIG.

这样，在移动网络移动后，大量减少了 MN、 FN和 MR向 RVS发送位置更新消息的数量，提高了网络的性能，减少了对网络资源的浪费。移动网络移动后 MR向 RVS、出口网关发送位置更新消息如图 8所示。 In this way, after the mobile network moves, the number of location update messages sent by the MN, FN, and MR to the RVS is greatly reduced, the performance of the network is improved, and the waste of network resources is reduced. After the mobile network moves, the MR sends a location update message to the RVS and the egress gateway as shown in Figure 8.
