Description

寻呼方法、无线网络控制器和接入网关 Paging method, an access gateway and the radio network controller

技术领域 FIELD

[0001] 本发明涉及移动通信领域,尤其涉及移动通信系统中的寻呼方法及无线网络控制器和接入网关。 [0001] The present invention relates to the field of mobile communications and more particularly relates to a paging method in a mobile communication system and a radio network controller and the access gateway.

背景技术 Background technique

[0002] 目前,全球无线通信正呈现出移动化、宽带化和IP化的趋势。 [0002] Currently, the world is showing a mobile wireless communication, broadband and IP trend. 宽带无线接入向移动化发展给移动通信技术带来了直接的竞争压力。 Access to mobile broadband wireless mobile communication technology development to bring direct competitive pressure. 因此3GPP和3GPP2两大第三代移动通信标准化组织先后开始了3G演进型系统(E3G)的技术研究与标准化工作,以保持3G技术的竞争力和在移动通信领域的领导地位。 Therefore, 3GPP and 3GPP2 two major third generation mobile communication standards organization has started a 3G evolution systems (E3G) technology research and standardization work in order to maintain the competitiveness of 3G technology and leadership in the field of mobile communications.

[0003] 3GPP2的空中接口演进工作分为Phasel和Phase2两个阶段,其中Phasel完成多载波HRPD (HRPD-High Rate Packet Data,高速分组数据)即NxEV-DO,主要目 Air Interface Evolution work [0003] 3GPP2 Phasel and Phase2 is divided into two phases, wherein Phasel complete multicarrier HRPD (HRPD-High Rate Packet Data, HRPD) i.e. NxEV-DO, the main purpose

标是提高峰值数据速率并保持后向兼容。 Standard is backward compatible is to improve the peak data rate and retention. 目前Phasel的技术标准EV-DO Rev B已经正式颁布。 Currently technical standards Phasel of EV-DO Rev B has been officially promulgated. Phase2阶段的峰值数据速率目标是前向链路依据不同的移动性,可以支持IOOMbps〜500Mbps ;反向链路支持50Mbps〜150Mbps,同时降低系统时延。 Phase2 peak data rate target phase is the forward link based on different mobility support IOOMbps~500Mbps; reverse link supports 50Mbps~150Mbps, while reducing system delay. Phase2 被CDG (CDMA Development Group,码分多址促进协会)正式命名为UMB (Ultra Mobile Broadband,超级移动宽带),UMB1.0标准已经被颁布。 Phase2 is CDG (CDMA Development Group, Code Division Multiple Access Promotion Association) officially named UMB (Ultra Mobile Broadband, Ultra Mobile Broadband), UMB1.0 standards have been promulgated. 与UMB相配套的网络架构已初步被确定,图1中给出了该网络结构中与数据缓存、寻呼相关的网络实体及接口。 And supporting the UMB network architecture has been preliminarily determined, in Figure 1 shows the network structure and the data cache, and paging-related physical network interfaces.

[0004] 参见图1,为现有技术中UMB网络参考架构模型示意图。 [0004] Referring to Figure 1, UMB network reference architecture model is a schematic view of the prior art. 图1中与数据缓存、 寻呼相关的实体包括EBS(Enhanced Base Station,增强基站)、SRNC(Signaling Radio Network Controller,信令无线网络控制器)和AGW(AccessGateway,接入网关)。 In FIG 1 and data caches, a paging-related entity comprises EBS (Enhanced Base Station, base station enhancement), SRNC (Signaling Radio Network Controller, the radio network controller signaling) and AGW (AccessGateway, access gateway).

[0005] EBS是演进的基站,其主要功能包括:支持UMB空口技术,在链路层完成加/ 解密和完整性保护,IP包头压缩,以及QoS调度等功能。 [0005] EBS is an evolved base station, whose main features include: support for UMB air interface technology, to complete the encryption / decryption and integrity protection in the link layer, the IP header compression, and QoS scheduling. EBS已经可以直接处理IP报文,体现了IP的边缘化趋势。 EBS can already deal directly with IP packets, it reflects the marginalization of IP.

[0006] SRNC的功能包括:接入认证,存储AT (Access Terminal,接入终端,包括 [0006] SRNC functions comprising: an access authentication, storing AT (Access Terminal, an access terminal, comprising

HRPD中使用的终端)与EBS间的会话信息,寻呼功能,终端空闲态的管理等。 Used HRPD terminal) and session information, the paging function, the idle state terminal management between EBS.

[0007] AGW是终端连接到IP业务网的第一跳,它完成IP业务认证、计费、本地移动性管理、QoS管理等功能。 [0007] AGW is connected to a first terminal hop IP network services, it completes the IP service authentication, billing, local mobility management, QoS management. 终端和网络间的用户面数据通过EBS和AGW进行传递,相比EVDO技术中数据面需要经过AN (Access Network,接入网设备)、PCF (Packet Control Function,分组数据控制功能)、PDSN(Packet DataSupport Node,分组数据支持节点) 三个节点而言,减少了数据面处理节点数目,有利于降低数据面传输时延,提高传输效率。 User plane data between the terminal and the network pass through EBS and AGW, EVDO technology compared to the data plane to go through AN (Access Network, access network device), PCF (Packet Control Function, a packet data control function), PDSN (Packet DataSupport node, in terms of packet data support node) three nodes, reducing the number of data processing nodes surface, help to reduce the data transmission delay surface, improving the transmission efficiency. 为实现用户数据包在EBS和AGW之间的传输,需要在二者之间为用户建立一个数据隧道。 To achieve transmit user data packets between the AGW and the EBS, the need to establish a tunnel for a user data therebetween. 目前假设该隧道采用PMIP (Proxy MIP,代理移动IP)的隧道。 Assuming that the tunnel current using the PMIP (Proxy MIP, Proxy Mobile IP) tunnel.

[0008] 现有技术还提供了基于上述UMB网络架构的寻呼流程。 [0008] The prior art also provides a process based on the paging UMB network architecture.

[0009] 参见图2,为现有技术中基于UMB网络架构的寻呼流程之一。 [0009] Referring to Figure 2, the prior art processes based on the one of the pages UMB network architecture. 在图2所示的寻呼模式中,EBS作为DAP (Data Attachment Point,数据附着点)承担缓存数据的功能。 In the paging mode shown in FIG. 2, EBS as DAP (Data Attachment Point, a data attachment point) assume the function of cached data. AT处于激活状态时,AGW通过PMIP隧道发送数据到EBS,EBS将数据发送到AT。 When the AT is in an active state, AGW transmits the data to the EBS through PMIP tunnel, EBS transmits the data to AT. 当AT接入空闲状态时,执行步骤: When access to an AT in an idle state, performing the steps of:

[0010] 步骤la-lb,当AT进入空闲状态时,释放连接,EBS将该UE进入空闲状态通知给SRNC。 [0010] Step la-lb, when the AT enters the idle state, releases the connection, the UE enters an idle state EBS notifies the SRNC.

[0011] 步骤2、当AGW接收到目标IP地址为该AT的数据分组后发送给EBS,由EBS [0011] Step 2, the received data when the target AGW IP address for the packet to the AT EBS, the EBS

缓存该AT的数据。 Cache data of the AT.

[0012] 步骤3、EBS通知SRNC发起针对该AT的寻呼。 [0012] Step 3, EBS notify the SRNC initiate paging for the AT.

[0013] 步骤4、SRNC向EBS发送寻求请求消息(Paging Request),寻呼该AT。 [0013] Step 4, SRNC sends a request message seeking EBS (Paging Request), to page the AT.

[0014] 步骤5、EBS发送寻呼消息,寻呼该AT。 [0014] Step 5, EBS sends a paging message to page the AT.

[0015] 步骤6、AT响应寻呼消息后,与EBS建立空口连接。 [0015] Step 6, the AT responds to the paging message, establishing the air interface connection EBS. 此后,AT就可以从EBS 接收缓存数据,或通过EBS与AGW进行数据传输。 Thereafter, AT can be received from the EBS data cache, or data transmission via the EBS AGW.

[0016] 图2所示的寻呼模式中,将数据缓存在EBS上可能造成数据乱序,这是原因: AT可能离开释放连接的EBS,而数据仍然缓存在原来的EBS上。 Paging pattern shown in [0016] FIG. 2, the data in the cache data may cause disorder EBS, which is the reason: AT EBS may leave the release of the connection, and the data cache is still on the original EBS. 当AT响应寻呼并与新的EBS建立连接后,新的数据通过新建立的PMIP隧道发送到新的EBS,缓存在原EBS的数据需要被转发。 When the AT responds to the page and establish a connection with the new EBS, the new data is sent to the new PMIP tunnel EBS through the newly created cache data needs to be forwarded to the original EBS. 新的数据有可能比缓存的数据先被传送到终端,从而导致数据乱序。 The new data may be compared to the cached data is transmitted to the terminal, resulting in scrambled data. 数据乱序损害延时敏感的实时业务的业务质量。 Damage data out of order delay-sensitive real-time business service quality.

[0017] 另外,将数据缓存在EBS上可能造成三角路由,这是因为:在仍使用该终端的原有PMIP隧道的时候,数据从AGW通过原PMIP隧道到达原来的EBS,再到达新的EBS,最后被发至终端,形成三角路由。 [0017] In addition, the data cache can cause triangular routing on EBS, this is because: when the PMIP tunnel that still use the old terminal, and EBS original data arrives by former PMIP tunnel from the AGW, and then reach the new EBS , and finally it is sent to the terminal to form a triangular routing. 三角路由将增加延时、消耗额外的传输带宽和处理能力。 The triangular route will increase the delay, consuming additional bandwidth and processing power.

[0018] 参见图3,为现有技术中基于UMB网络架构的寻呼流程之二。 [0018] Referring to Figure 3, the prior art is based on the paging process of the UMB network architecture II. 在图3所示的寻呼模式中,由AGW承担缓存数据的功能。 In the paging mode shown in FIG. 3, assume the function of the data cached by the AGW. AT处于激活状态时,AGW通过PMIP隧道发送数据到EBS2,EBS2将数据发送到AT。 When the AT is in an active state, AGW transmits the data to the PMIP tunnel through EBS2, EBS2 transmits the data to AT. 当AT接入空闲状态时,执行步骤: When access to an AT in an idle state, performing the steps of:

[0019] 步骤la-lb,当AT进入空闲状态时,释放连接,EBS2将该UE进入空闲状态通知给SRNC。 [0019] Step la-lb, when the AT enters the idle state, releases the connection, the UE enters an idle state EBS2 notifies the SRNC.

[0020] 步骤2-3、若AT移动到EBSl,则向SRNC进行注册和位置登记,SRNC将该AT移动到EBSl的信息通知EBS2。 [0020] Step 2-3, when the AT moves to EBSl, the registration and the location registration SRNC, SRNC to the mobile AT information notification EBSl EBS2.

[0021] 步骤4、EBS2触发AGW缓存该AT的数据。 [0021] Step 4, EBS2 trigger AGW cache data of the AT.

[0022] 步骤5、当AGW接收到目标IP地址为该AT的数据分组后进行缓存并通知EBS2。 [0022] Step 5, when the data to the destination IP address of the AGW receives the AT for the packet and notifies the cache after EBS2.

[0023] 步骤6、EBS2通知SRNC发起针对该AT的寻呼。 [0023] Step 6, EBS2 notify the SRNC initiate paging for the AT.

[0024] 步骤7、SRNC向各EBS发送寻求请求消息,寻呼该AT。 [0024] Step 7, SRNC transmits to each EBS seek request message, to page the AT.

[0025] 步骤8、各EBS通过空口寻呼该AT。 [0025] Step 8, each page the AT via EBS air interface.

[0026] 步骤9、AT响应EBSl的寻呼消息,与EBSl建立空口连接。 [0026] Step 9, AT EBSl response to the paging message to establish the air interface connection EBSl.

[0027] 步骤10、EBSl和AGW间为AT建立PMIP隧道。 [0027] Step 10, and between EBSl AGW established PMIP tunnel AT. 此后,该AT就可以通过EBSl与AGW进行数据传输。 Thereafter, the AT can transmit data via EBSl with AGW.

[0028] 图3所示的寻呼模式中,在寻呼空闲态的终端时,AGW通过EBS触发SRNC发起寻呼,处理过程较多,增加了网络时延。 Paging pattern shown in [0028] FIG 3, when the paging terminal idle state, the AGW trigger SRNC initiates paging by EBS, the process is more, increased network latency.

[0029] 现有技术还可以将上述两种寻呼模式结合起来,在AT移动范围不大时采用图2所示的寻呼模式,在终端移动范围大时,采用图3所示的寻呼模式。 [0029] The prior art also can combine the two modes of paging, paging using mode shown in FIG. 2 when the AT is not moving range, when the terminal moves a large range, as shown in FIG. 3 Paging mode. 但是这种方式造成寻呼的逻辑十分复杂,需要判断AT移动的范围来决定使用哪种模式,因此降低了系统效率。 But for this very complex way paging logic, we need to determine the scope of AT movement to determine which mode to use, thus reducing the efficiency of the system.

AGW将该用户的下行数据通过PMIP隧道发送到DAP。 The AGW transmits downlink data to the user through the DAP PMIP tunnel. DAP通过FLSA (Forward Link Serving AN,前向链路服务AN)发送给终端接收;终端将该用户的上行数据发给RLSA (Reverse Link Serving AN,反向链路服务AN),RLSA将该数据通过PMIP隧道发送到AGW。 DAP by FLSA (Forward Link Serving AN, forward link serving AN) is sent to the receiving terminal; user terminal the uplink data sent RLSA (Reverse Link Serving AN, the reverse link serving AN), RLSA the data PMIP tunnel is sent to the AGW. DAP、RLSA和RLSA可以分别由不同的eBS来承担,本实施例中假设源eBS既是DAP又是FLSA和RLSA。 DAP, respectively RLSA and can be borne by the RLSA different eBS, a source eBS example assumes both DAP and RLSA FLSA is present embodiment. 终端进入空闲状态,以及通过网络寻呼激活该终端并接收网络发送的用户数据的过程具体如下: Process terminal enters an idle state, and activating the paging terminal via a network and receive user data transmitted through the network as follows:

[0060] 步骤la-lb、终端释放连接,进入空闲状态。 [0060] Step la-lb, the terminal releases the connection, into an idle state. 源eBS将终端进入空闲状态的信 EBS source terminal into an idle state letter

息通知给SRNC。 Interest rates notified to the SRNC. 终端和SRNC将保留用户会话信息。 SRNC maintains the user terminal and session information.

[0061] 步骤2、SRNC向AGW发送缓存数据的指示消息,该指示消息携带终端标识AT-ID作为参数。 [0061] Step 2, SRNC sends an instruction message to the cached data AGW, the indication message carries the terminal identifier AT-ID as a parameter. AGW收到SRNC的指示消息后,准备为该AT-ID对应的终端缓存数据。 After SRNC receives the AGW indication message, ready for AT-ID corresponding to the terminal buffer data.

[0062] 步骤3a-3b、该终端移动到其它区域。 [0062] Step 3a-3b, the terminal moves to other areas. 若该终端移动到目标eBS,则通过目标eBS向SRNC进行注册和位置登记。 If the terminal moves to a target eBS, the registration and location registration to the SRNC via the target eBS.

[0063] 步骤4、当目标IP地址为该终端的数据分组到达AGW时,AGW将接收到的数据分组缓存起来。 [0063] Step 4, when the data for the destination IP address of the terminal when the packet reaches the AGW, AGW received data packets cached. 同时,AGW向SRNC发送数据到达的指示消息,该指示消息中携带AT-ID作为参数。 Meanwhile, AGW sends an instruction message to the data arrival SRNC, carrying AT-ID as a parameter indicative of the message.

[0064] 步骤5、SRNC收到AGW的指示消息后,根据消息中携带的AT_ID得到该终端的位置信息。 After [0064] Step 5, SRNC AGW indication message received to obtain the location information of the terminal according to the message carried AT_ID. 随后SRNC向该终端所处的寻呼范围的所有eBS发出寻呼请求消息。 Then issuing a paging request message to the SRNC eBS all terminals located in the paging range.

[0065] 步骤6、接收到SRNC寻呼请求消息的所有eBS在空中接口发出寻呼请求消息。 [0065] Step 6, the SRNC receives a paging request message to all the paging request message sent eBS air interface.

[0066] 步骤7a-7b、若该终端正在监测目标eBS的信号,则该终端收到目标eBS发出的寻呼请求消息后,响应该寻呼请求消息,随后建立该终端到目标eBS的空口连接。 [0066] Step 7a-7b, if the terminal is monitoring the signal of the target eBS of the target eBS terminal receives a paging request message sent in response to the paging request message, then the establishment of the terminal to the target air interface connection eBS . 空口连接建立后,目标eBS将终端进入连接状态的信息通知给SRNC。 Notify the air interface connection is established, the target eBS terminal into a connected state to the SRNC.

[0067] 步骤8、SRNC向AGW发送传输数据的指示消息,该指示消息中携带AT_ID和该终端当前的服务eBS的信息(本实施例中是目标eBS的标识或地址信息)作为参数。 [0067] Step 8, SRNC sends an instruction message to the transmission data AGW, the indication message carries information of the current serving eBS AT_ID and the terminal (identification or address information of the target eBS embodiment of the present embodiment is) as a parameter.

[0068] 步骤9、目标eBS为该终端建立到AGW的PMIP隧道。 [0068] Step 9, the AGW to establish a target eBS PMIP tunnel for the terminal. 此后,AGW通过该隧道将该终端的数据发送到目标eBS,目标eBS将该数据通过空口连接发送到该终端。 Thereafter, the AGW transmits the data to the target eBS through the tunnel of the terminal, a target eBS transmitting the data to the terminal through an air interface connection.

[0069] 本实施例中,由于原来为该终端建立PMIP隧道连接的是源eBS,而后来由目标eBS接受该终端的寻呼响应,并建立新的连接,因此该终端当前的服务eBS为目标eBS, 已经不是原来为该终端建立PMIP隧道的源eBS,因此需要执行步骤9,由终端当前的服务eBS为该终端建立起新的PMIP隧道。 [0069] In this embodiment, since the original connection establishment PMIP tunnel is a source eBS, and then the terminal receiving the paging response by the target eBS, and establish a new connection, and therefore the current serving eBS that the terminal is a targeted terminal eBS, not the original source eBS established PMIP tunnel for the terminal, it is necessary to step 9, the current serving eBS to establish a new PMIP tunnel for the terminal.

[0071] 本实施例描述了由AGW承担缓存数据的功能,由SRNC触发AGW开始缓存数据,由AGW触发SRNC发起寻呼,并且通过新建立的空口连接与原有隧道传送数据的过程。 [0071] This example describes the commitment by the AGW function of cache data, the cache data AGW starts triggered by the SRNC, the SRNC initiates paging AGW triggered, and the process of connecting the original data by tunneling newly established air interface.

[0072] 参见图5,为本发明实施例二中基于UMB网络架构的寻呼流程示意图。 [0072] Referring to Figure 5, the present embodiment two paging schematic flow UMB network architecture based on the invention.

[0073] 终端附着到网络后,与源eBS之间建立空口承载,源eBS和AGW之间建立PMIP隧道连接,终端和AGW之间通过建立的连接传输数据。 After [0073] the terminal attached to the network, air interface bearer established between the source and the eBS, between the source eBS and AGW to establish PMIP tunnel connection established via a data transmission connection between the terminal and the AGW. 终端进入空闲状态,以及使用通过网络寻呼新建立起来的空口连接与原有的隧道接收网络发送的用户数据的过程,具体如下: Terminal enters an idle state, and by using the new established air interface paging network connection process with the original transmitted user data receiving network tunnel, as follows:

[0074] 步骤la-lb、终端释放连接,进入空闲状态。 [0074] Step la-lb, the terminal releases the connection, into an idle state. 源eBS将AT进入空闲状态的信息 AT enter the information source eBS idle state

通知给SRNC。 Notified to the SRNC. 终端和SRNC将保留用户会话信息。 SRNC maintains the user terminal and session information.

[0075] 步骤2、SRNC向AGW发送缓存数据的指示消息,该指示消息携带终端标识AT-ID作为参数。 [0075] Step 2, SRNC sends an instruction message to the cached data AGW, the indication message carries the terminal identifier AT-ID as a parameter. AGW收到SRNC的指示消息后,准备为该AT-ID对应的终端缓存数据。 After SRNC receives the AGW indication message, ready for AT-ID corresponding to the terminal buffer data.

[0076] 步骤3、当目标IP地址为该终端的数据分组到达AGW时,AGW将接收到的数据分组缓存起来。 [0076] Step 3, when the data for the destination IP address of the terminal when the packet reaches the AGW, AGW received data packets cached. 同时,AGW向SRNC发送数据到达的指示消息,该指示消息中携带AT-ID作为参数。 Meanwhile, AGW sends an instruction message to the data arrival SRNC, carrying AT-ID as a parameter indicative of the message.

[0077] 步骤4、SRNC收到AGW的指示消息后,根据消息中携带的AT_ID得到该终端的位置信息。 [0077] Step 4, after receiving an instruction message AGW SRNC to obtain location information of the terminal according to the message carried AT_ID. 随后SRNC向该终端所处的寻呼范围内的所有eBS发出寻呼请求消息。 Then issuing a paging request message to the SRNC eBS all the terminal is located in the paging range.

[0078] 步骤5、接收到SRNC寻呼请求消息的所有eBS在空中接口发出寻呼请求消息。 [0078] Step 5, the received paging request message to the SRNC all eBS in the paging request message sent over the air interface.

[0079] 步骤6a-6b、该终端正在监测源eBS的信号,收到源eBS发出的寻呼请求消息后,响应该寻呼请求消息,随后建立该终端到源eBS的空口连接,源eBS将终端进入连接状态的信息通知给SRNC。 [0079] Step 6a-6b, the terminal is monitoring the signal source eBS, a source eBS receives a paging request message sent in response to the paging request message, then the establishment of the air interface to a source terminal connected to the eBS, the source eBS into a connected state the information terminal notifies the SRNC.

[0080] 步骤7、SRNC向AGW发送传输缓存数据的指示消息,该指示消息中携带AT-ID和该终端当前的服务eBS的信息(本实施例中是源eBS的标识或地址信息)作为参数。 [0080] Step 7, SRNC sends an instruction message transmitting cached data to the AGW, information of the current serving eBS of AT-ID and the terminal of the indication message carries (identity or address information of eBS present embodiment, the source) as a parameter . AGW收到该指示消息后,将该终端的数据发送到指示消息中指定的eBS。 After the AGW receives the message indication, transmits the data message indicating that the terminal specified eBS.

[0081] 本实施例中,指示消息中指定的eBS,即终端当前的服务eBS仍然是原来为该终端建立PMIP隧道的源eBS,则AGW立即通过原来的PMIP隧道发送数据到源eBS,再由源eBS通过空口连接发送到该终端。 [0081] In this example embodiment, the message indicating the specified eBS, i.e. the current serving eBS PMIP tunnel establishment is still the original source of the terminal for the eBS, the AGW immediately transmit data to the original source eBS by PMIP tunnel, then by source eBS transmitted to the terminal through an air interface connection.

[0082] 在上述实施例一和实施例二中,在SRNC向AGW发送的缓存数据的指示消息, 以及AGW向SRNC发送的数据到达的通知消息,以及SRNC向AGW发送传输缓存数据的指示消息,都携带AT-ID参数。 [0082] In the above embodiment one and two embodiments, the indication message buffers data transmitted to the AGW in SRNC, and a notification message data AGW transmitted to the SRNC arrives, and the SRNC sends the transmit buffer data to the AGW indication message, carries AT-ID parameter. 此处的AT-ID建议采用用户的NAI (Network Access Identifier,网络接入标识)。 AT-ID here suggested user NAI (Network Access Identifier, NAI). 因为AGW保存每个用户的NAI信息。 Because AGW save each user's NAI information. 而SRNC作为设备认证点,也可以从AAA(验证,鉴权与计费)服务器获得用户的NAI信息。 And a device authentication SRNC point, from the AAA (authentication, authorization and accounting) server obtains the NAI of the user information.

[0083] AT-ID 还可以采用AGW 与DAP 之间GRE 隧道(Generic RoutingEncapsulation, 通用路由封装协议)的Key值。 [0083] AT-ID value may also be employed Key GRE tunnels (Generic RoutingEncapsulation, generic routing encapsulation protocol) between the AGW and the DAP. 由于在某个AGW下,每个终端的GRE Key值都不相同而且是唯一的,因此也可以使用该值标识终端。 Since in certain AGW, GRE Key values ​​are not the same and each terminal are unique, and therefore can also use this value to identify the terminal. 该GRE Key值由AGW分配,若SRNC 为终端建立eBS与AGW之间的PMIP隧道,SRNC也知道该Key值;若不是由SRNC为终端建立eBS与AGW之间的PMIP隧道,则可以由eBS在建立完PMIP隧道后通知SRNC PMIP隧道的GREKey值。 The value of the GRE Key AGW assigned, if the SRNC establish a PMIP tunnel between the eBS and AGW terminal, the SRNC knows Key value; if PMIP tunnel is established between the eBS and AGW SRNC by the terminal, it is possible by the eBS notify the SRNC PMIP tunnel Once you have created PMIP tunnel GREKey value.

[0084] AT-ID还可以是由SRNC产生的该SRNC内唯一的号码,如序列号。 The unique number of the SRNC [0084] AT-ID may also be produced by the SRNC, such as serial numbers. 一个号码标识一个终端,一个SRNC内所有终端的号码都不相同。 Identifying a number of a terminal, all terminals in a number of SRNC is not the same. SRNC分配该号码后将该号码通知AGW。 After the SRNC assigns the number notification number AGW. SRNC生成标识终端的号码以及通知AGW的过程可以发生在终端进行网络附着的过程,例如,在鉴权过程中,SRNC可以为该终端分配一个标识号码,并在鉴权交互过程中,将SRNC分配的用户标识号码通知给AGW。 SRNC terminal identification number and generating a notification process can take place in the AGW terminal during network attachment, e.g., in the authentication process, the SRNC may be assigned an identification number for the terminal, and the authentication interaction process, the SRNC distribution the user identification number to the AGW.

[0085] 类似地,AT-ID还可以是由AGW产生的该AGW内唯一的号码,如序列号。 The unique number of the AGW [0085] Similarly, AT-ID may also be produced by the AGW, such as serial numbers. 一个号码标识一个终端,一个AGW内所有的终端的号码都不相同。 A number of a terminal identifier, a number of all the terminals are not the same AGW.

绑定完成时,通过该PMIP隧道发送终端的缓存数据到eBS,再由eBS发送到该终端。 When binding is completed, the terminal transmits through the eBS PMIP tunnel to cache data, then sent to the terminal by the eBS. 由于本实施例中,终端当前的eBS不是该终端的源eBS,因此需要在终端当前的eBS与AGW间建立新的PMIP隧道,以进行数据传输。 Since the present embodiment, the current source eBS eBS than the terminal end, it is necessary to establish a new PMIP tunnel between the eBS and AGW current terminal for data transmission.

[0092] 本实施例中,当AGW向SRNC发送数据到达的通知消息时,可以启动定时器, 若定时器超时可还未收到SRNC返回的数据到达通知的响应,则有可能是因为寻呼失败,AGW可以再次向SRNC发送数据到达的通知消息,以触发SRNC再次寻呼该终端。 [0092] In this embodiment, when the AGW sending a notification message to the SRNC data arrives, the timer can be started, the timer expires if the SRNC can not receive data returned in response to the notification arrives, it may be because the paging failure, AGW may send a notification message to the SRNC data arrives again, the paging terminal to trigger SRNC again. 步骤8的数据到达通知的响应步骤也可以是可选步骤。 Step 8 data arrival notification response step may be an optional step.
