Description
本發明係有關於無線網路,特別係有關於用於路由資料流量的網際網路協定介面選擇。
本地(local)網際網路協定(IP)存取可提供作為屬於如住家網路(residential network)或企業網路(enterprise network)等相同本地網路(local network)之無線發射/接收單元(wireless transmit/receive unit,WTRU)間的通信。本地IP存取致能WTRU連接到作為本地網路一部分之家用演進節點B(home evolved Node B,HeNB),可用以存取其他本地IP存取-致能WTRU,其附加於相同本地網路一部分之家用演進節點B(HeNB)。
選擇網際網路協定流量卸載(selected IP traffic offload,SIPTO)可提供選擇流量的卸載,如網際網路流量,至一IP網路,此IP網路接近WTRU到存取網路之一附加點。網際網路協定介面選擇的操作者策略(operator policy for IP interface selection,OPIIS)被創建以選擇
WTRU中的IP介面作為路由IP流於第三代合作夥伴計劃(third generation partnership,3GPP)以及non-3GPP兩者存取中的不同介面。OPIIS策略可藉由存取網路尋找與選擇功能(ANDSF)加以實現,期可協助WTRU尋找non-3GPP存取網路以及管理3GPP及non-3GPP網路的連接。OPIIS可檢測系統架構並提供操作者策略給使用ANDSF架構的UE。UE可藉由評估存取點名稱(access point name,APN)間路由策略(Inter Access Point Name Routing Policy,IARP)以及系統間路由策略(Inter-System Routing Policy,ISRP)兩者以決定如何路由IP流。

以下將以實施範例說明以為參考,且使用特定語言描述。然應理解其非用以限定本發明。
在本發明揭露及描述前,應理解本發明並不限於在此所述之特定結構、程序步驟或材料,熟習本發明所屬技術領域者可等效重組擴充本發明。也應理解在此所用之術語係為描述特定範例之用,亦非用以限定本發明。不同圖式中的相同符號代表相同元件。流程圖或程序圖中的編號係用以說明步驟及操作而不代表特定的順序或程序。
網際網路協定介面選擇的操作者策略(operator policies for IP interface selection,OPIIS)可設定選擇IP介面之操作者策略。傳統上,用於支援存取點名稱(APN)間路由策略(IARP)以及無法同時路由IP流量流於多重無線電存取介面的用戶設備(UE)的操作者策略規則將評估IARP並決定是否有任何策略與IP流匹配。與IP流匹配最高優先權的IARP會被選擇作為封包資料網路(packet data network,PDN)連接,如相關於策略中較佳APN之一連接,其用以路由IP流。傳統上,操作者策略規則提供可同時於多重無線電存取介面上路由IP流量的UE使用系統間路由策略(inter-system routing policy,ISRP)及IARP。UE藉由評估ISRP及IARP兩者決定如何路由IP流。
當UE使用傳統路由規則以評估IARP及ISRP策略
時,路由規則發生衝突。傳統上,UE藉由評估IARP及ISRP決定如何路由IP流。用於非無縫無線區域網路(WLAN)卸載(NSWO)的過濾規則相對於用於IARP的過濾規則具有相對較高優先權。當UE依循傳統規則且資料流量或IP流與IARP規則及NSWO規則兩者匹配時,即產生規則衝突。IARP及ISRP間路由規則衝突的發生是由於NSWO事件。
在一實施例中,可利用設定優先權規則解決IARP及ISRP規則的衝突,其中IARP可於ISRP前進行評估。舉例而言,為決定IP介面以路由IP流,UE可被組態先評估IARP接著再評估ISRP。在一實施例中,IARP可指示於不同PDN連接間被路由的資料流量或IP流,以及流量應被非無縫卸載至一WLAN。當UE先評估IARP以決定IP介面時,輸出規則可為APN_x參數。當UE在IARP後評估ISRP以決定IP介面時,APN_x參數可作為額外輸入。
在另一實施例中,欲解決IARP規則及ISRP規則間的衝突,IARP可包含APN間(inter-APN)規則及NSWO策略。當IARP包含NSWO策略時,UE可決定相關於ISRP的NSWO優先權階層。舉例而言,當IARP包含NSWO,UE可以APN_x作為額外輸入於IARP之後評估ISRP。優先權階層可被設定使UE決定ISRP不會被組態,以使NSWO被選擇作為有關一APN較高優先權,如APN_x,而有關另一APN較低優先權,如APN_y。IARP包含
NSWO及APN間規則的一優點是可提供存取網路尋找與選擇功能(Access Network Discovery and Selection Function,ANDSF)彈性以定義IARP及NSWO兩者之優先權。
第1圖顯示於ANDSF管理物件(MO)下的節點(node)及葉物件(leaf object)。第1圖更顯示ANDSF MO可用於管理系統間路由策略(ISRP)及存取點名稱間路由策略(IARP)。在一實施例中,ANDSF MO可存取策略資訊(policy information)、尋找資訊(discovery information)、UE位置資訊以及儲存於UE中的UE的概要(profile)資訊。在一範例中,NSWO分流(branch)可被加入IARP策略中而ANDSF MO可基於NSWO分流至IARP策略的增加進行修改。
在一實施例中,ANDSF MO的一或多節點(node)或葉(leaf)可被UE使用以決定路由策略規則是否合法。例如,UE可先使用ANDSF MO之下的IARP節點或葉以決定路由策略規則是否合法。在一實施例中,UE可決定IARP路由策略為合法的且使用IARP節點及葉物件以路由IP流,如第10圖所示。在一實施例中,當所選擇條件發生在ANDSF MO的路由標準下時,UE可決定IARP路由策略為合法的,如第8圖中所示interAPNRouting標準以及第11圖中所示ForNonSeamlessOffload標準。在另一實施例中,UE可決定IARP為不合法的。當UE決定IARP為不合法時,則UE可決定ISRP為合法的並使用ISRP節點
及葉物件以路由IP流,如第5圖中所示。
第2圖顯示於ANDSF MO中路由IP流量策略之列表。第2圖更顯示來自第1圖之ANDSF MO可包含一策略列表。在一實施例中,此策略列表可包含:規則優先權(rule priority);優先存取(prioritized access)資訊;合法區域(validity area)資訊;漫遊(roaming)資訊;公共陸地行動網路(public land mobile network,PLMN)資訊;日期時間資訊以及更新策略資訊。
第3圖顯示於ANDSF MO中路由IP流量尋找資訊之列表。第3圖更顯示來自第1圖之ANDSF MO可包含一尋找資訊列表。在一實施例中,此尋找資訊列表可包含:存取網路類型(access network type)資訊、存取網路區域(access network area)資訊、存取網路資訊參考以及PLMN資訊。
第4圖顯示於ANDSF MO中路由IP流量之一UE位置資訊列表。第4圖更顯示來自第1圖之ANDSF MO可包含之UE位置資訊列表。在一實施例中,此UE位置資訊列表可包含:第三代合作夥伴計劃(third generation partnership,3GPP)位置資訊、全球互通微波存取(worldwide interoperability for microwave access,WiMAX)位置資訊、WLAN位置資訊、地理(Geo)位置資訊以及已註冊PLMN(RPLMN)資訊。在一實施例中,位置資訊可為3GPP長期演進(Long Term Evolution,LTE)Rel.8、9、10、11或12網路及/或美國電機電子工程師學會(Institute
of Electrical and Electronics Engineers,IEEE)802.16p、802.16n、802.16m-2011、802.16h-2010、802.16j-2009、802.16-2009。
第5圖顯示於ANDSF MO中路由IP流量之一ISRP策略列表。第5圖更顯示來自第1圖之ANDSF MO可包含ISRP策略列表。在一實施例中,此ISRP策略列表可包含:如第6圖所示以流為基礎(flow based)的資訊;如第7圖所示以服務為基礎(service based)的資訊;如第8圖所示NSWO策略列表;漫遊資訊;PLMN資訊以及更新策略資訊。
第6圖顯示於ANDSF MO中用於路由IP流量之ISRP以流為基礎的資訊之一列表。第6圖更顯示來自第5圖之ISRP可包含以流為基礎的資訊列表。在一實施例中,此以流為基礎的資訊列表可包含:IP流資訊、路由標準資訊、路由規則資訊以及規則優先權資訊。
第7圖顯示於ANDSF MO中用於路由IP流量之ISRP以服務為基礎的資訊之一列表。第7圖更顯示來自第5圖之ISRP可包含以服務為基礎的資訊列表。在一實施例中,此以服務為基礎的資訊列表可包含:路由標準資訊、路由規則資訊以及規則優先權資訊。
第8圖顯示於ANDSF MO中用於路由IP流量的NSWO策略之一列表。第8圖更顯示來自第5圖之ISRP可包含NSWO策略列表。在一實施例中,此以流為基礎的資訊列表可包含:IP流資訊、路由標準資訊、路由規則
資訊以及規則優先權資訊。
第9圖顯示於ANDSF MO中用於路由IP流量之UE概要資訊之一列表。第9圖更顯示來自第1圖之ANDSF MO可包含UE概要資訊列表。在一實施例中,此UE概要資訊列表可包含裝置容量(DevCapability)資訊。
第10圖顯示於ANDSF MO中用於路由IP流量之IARP策略之一列表。第10圖更顯示來自第1圖之IARP列表可包含APN間規則及NSWO策略。在一實施例中,此IARP策略列表可包含:如第11圖所示之APN間資訊;如第8圖所示之NSWO;漫遊資訊、PLMN資訊以及更新策略資訊。
第11圖顯示具有APN路由規則及APN優先權路由規則之APN間路由規則之一列表。第11圖更顯示來自第10圖之IARP列表可包含APN間規則列表。在一實施例中,此APN路由規則可包含NSWO路由策略。在一實施例中,APN間規則列表可包含:IP流資訊、路由標準資訊、路由規則資訊以及規則優先權資訊。
在第11圖中,對APN間路由可對NSWO情況指派一特定值予APN節點。此特定值可用以設定NSWO的優先權階層以致能NSWO根據IARP進行評估。在一實施例中,此特定值定義於3GPP技術規格(Technical Specification,TS)12.4.0版的節5.9.28中,如同<X>/IARP/<X>/ForInterAPNROuting/<X>/RoutingRule/<X>/APN。
在第11圖中,對特定流分派規則APN葉可指示APN
為合法的。在一實施例中,對NSWO情形可指派一特定值予APN。在另一實施例中,此特定值可包含如發生(occurrence)為one、格式(format)為chr、存取類型(access type)為get、replace以及值為APN等資訊。在一實施例中,NSWO APN可被編碼為以#作為NSWO APN的單一標籤之APN,如用於此#的具有值one 1的長度octet位元組的碼,依據美國資訊交換標準碼(American standard code for information interchange,ASCII)。
第12圖顯示具有路由規則之APN間路由規則之一列表,路由規則包含APN路由規則以及具有分離NSWO葉節點之APN優先權路由規則。分離NSWO葉節點可指示NSWO情形的優先權。具有分離NSWO葉節點,NSWO的優先權可根據IARP的優先權加以評估。第12圖在其他方面與第11圖是相同的。
傳統路由規則可於ISRP以及系統間行動策略(inter-system mobility policy,ISMP)情形中提供漫遊(roaming)規則。然而,當UE遵循傳統路由規則以評估IARP及ISRP策略時,此等傳統路由規則無法強調IARP漫遊情形。在ISRP及ISMP中的漫遊規則無法提供家用路由(home-routed)相對於IARP本地分匯(local breakout)的規則,例如當家用公共陸地行動網路(home public land mobile network,H-PLMN)決定何時允許本地分匯及何時不允許本地分匯。傳統上,ISRP及ISMP的漫遊規則也無法優先化
由家用ANDSF(H-ANDSF)對所選擇的情形所提供的IARP。ISRP及ISMP的漫遊規則也無法對H-ANDSF中的IARP與查訪存取網路尋找與選擇功能(V-ANDSF)所提供的ISRP或ISMP之間的互動提供規則。
此外,傳統上,IARP優先權的漫遊情形必須根據來自家用操作者的策略進行評估,以及ISRP優先權必須根據來自參訪操作者的策略進行評估。在不同操作者間,這些優先權值並非連續的,以及可能導致UE對不同情形做成不連續或做成不同決定。
在一實施例中,為強調IARP漫遊情形的路由規則,UE可使用來自H-ANDSF家用操作者的APN。家用操作者可根據使用者描述以APN組態UE。在一實施例中,由家用操作者所組態的APN對V-ANDSF的參訪操作者可為透明的。舉例而言,參訪操作者可能並不知道在UE中對IARP漫遊情形的實際APN組態。在一實施例中,當UE接收來自V-ANDSF如IARP或ISRP之路由策略時,UE可以忽略所接收之路由策略。
在另一實施例中,為強調IARP漫遊情形的路由規則,UE可由家用操作者對特定APN預先組態,此用於當UE連接至一或多較佳參訪漫遊夥伴(visited roaming partner)時。預先組態特定APN之一優點是UE不必對參訪情形自AND SF動態的載入APN資訊。
傳統路由規則提供過濾規則(filter rule)可識別哪個APN被匹配特定IP過濾器(filter)的IP流所限制。對傳統
路由規則而言,過濾規則可僅被施用於當路由規則引導IP流量至一現存(即已建立)之PDN連接時。傳統上,當過濾規則中沒有APN與現存PDN連接相關時,不會施用過濾規則。傳統規則無法涵蓋IARP施用至新PDN連接的情形。
在一實施例中,為涵蓋IARP施用至新PDN連接的情形,IARP可被限制於現存PDN連接。限制IARP至現存PDN連接可限制UE利用在IARP中為建立新PDN連接之可用資訊的彈性。在一實施例中,IARP中的資訊可施用至新的PDN連接。在另一實施例中,過濾規則基於被起始以創建具有特定路由標準之PDN連接的特定應用程式可施用至IARP。在一實施例中,應用程式識別(application identification,AppID)於IP流節點中的分流可用以設定IARP中的可用資訊。在另一實施例中,路由標準可基於應用程式類型、應用程式類組及/或PDN連接。舉例而言,聲音(voice)應用程式、視訊(video)應用程式以及即時訊息服務(instant messaging service,IMS)應用程式可為不同類型之應用程式以及可選擇過濾規則作為IARP的部分。
另一範例提供在通信網路中可操作以選擇IP介面之UE的電腦網路之功能1300,如第13圖之流程圖所示。此功能可以方法實現或者此功能可為於一機器上所執行之指令,在此指令係包含在至少一電腦可讀媒體或一非暫態(non-transitory)機器可讀儲存媒體。電腦電路可被組態自

在一實施例中,IARP包含對NSWO及APN間規則。在另一實施例中,電腦電路可被組態對IARP自UE傳送一要求至ANDSF,其中ANDSF包括IARP以及ISRP。在另一實施例中,電腦電路可被組態自ANDSF接收對路由IP流量之APN間路由策略之一列表。在另一實施例中,電腦電路可被組態自ANDSF接收對路由IP流量之NSWO策略之一列表。在一實施例中,ISRP指示當UE透過多重存取連接至一EPC時如何於可用存取間分配流量。在另一實施例中,UE可包括一天線、一照相機、一觸感顯示螢幕(touch sensitive display screen)、一揚聲器、一麥克風、一圖形處理器、一應用程式處理器、內部記憶體或者一非揮發性記憶埠。
另一範例提供在通信網路中可操作以選擇IP介面之UE的電腦網路之功能1400,如第14圖之流程圖所示。此功能可以方法實現或此功能可為於一機器上所執行之指
令,在此指令係包含在至少一電腦可讀媒體或一非暫態機器可讀儲存媒體上。電腦電路可組態自操作於EPC中之一伺服器上的ANDSF接收本地策略資訊以及存取網路選擇資訊,如區塊1410所示。電腦電路更可被組態以決定在其上於實現其他路由策略前使用IARP以路由IP流的至少一IP介面,如區塊1420所示。電腦電路亦可被組態在使用IARP所選擇的至少一IP介面上自UE路由IP流,如區塊1430所示。
在一實施例中,IARP包括NSWO策略以及APN間規則。在另一實施例中,電腦電路可被組態以指派一選定值予一APN以致能NSWO之一或多優先權以APN間規則加以評估。在一實施例中,其他路由策略之至少一者為NSWO策略。在另一實施例中,當非無縫WLAN卸載被IARP所選擇時,電腦電路可被組態以對WLAN卸載路由IP流。在另一實施例中,當一APN被IARP所選擇時,電腦電路可被組態以路由IP流至對應此APN之PDN連接。在另一實施例中,電腦電路可被組態以選擇APN或非無縫WLAN卸載以路由用戶平面流量匹配特定IP流。
在另一實施例中,當APN或NSWO自路由特定IP流被限定時,電腦電路可被組態以決定。在另一實施例中,當IARP引導IP流至一現存PDN連接時,電腦電路可被組態對一APN使用IARP。在另一實施例中,當IARP引導IP流至一新的PDN連接時,電腦電路可被組態對一APN使用IARP。在另一實施例中,電腦電路可被組態以
施用過濾規則予所選定之應用程式,此等應用程式係用以依據所選擇的路由基準來創建一或多個PDN連接。在另一實施例中,電腦電路可被組態使用網際網路協定流(IPFlow)節點中AppID分路(branch)以決定過濾規則。在另一實施例中,電腦電路可被組態基於一應用程式類型(type)、一應用程式類組(class)或者一PDN連接以決定過濾規則。
第15圖使用流程圖1500說明於一通信網路中選擇IP介面之方法。此方法可包含於ANDSF上接收來自UE用於存取網路尋找資訊之一要求,如區塊1510所示。此方法更包含使用H-ANDSF以組態用於一UE之一APN,其中APN組態至少部分基於漫遊協議(roaming agreement),如區塊1520所示。此方法也可包含自H-ANDSF至UE通信APN,如區塊1530所示。在一實施例中,此方法也可包含使用H-ANDSF對UE預先組態一APN。在另一實施例中,此方法更可包含當UE連接至一偏好尋訪漫遊夥伴時,於UE使用預先組態之APN。
