对于终端, 除了在初始入网过程中需要鉴权外, 当满足重鉴权的条件时 还会进行重鉴权。 对于激活状态的终端, 终端、 服务基站、 锚定鉴权器都可 能触发对终端的重鉴权。 例如, 当这些网元(终端、 服务基站、 锚定鉴权器) 与安全上下文( Security Context )相关的某些定时器接近超时或者计数值接近 最大值时, 就会触发对终端进行重鉴权。 当终端进入空闲模式后, 保存有终 端安全上下文的网元同样可能触发对终端进行重鉴权。 For the terminal, in addition to the authentication required in the initial network access process, the re-authentication is performed when the condition of the re-authentication is satisfied. For an active terminal, the terminal, the serving base station, and the anchor authenticator may trigger re-authentication of the terminal. For example, when some of the timers associated with the security context (the terminal, the serving base station, the anchor authenticator) are close to the timeout or the count value is close to the maximum value, the terminal is re-authenticated. . After the terminal enters the idle mode, the network element that stores the terminal security context may also trigger re-authentication of the terminal.
由于终端重鉴权是终端和鉴权授权计费( Authentication , Authorization , Accounting, 简称 AAA )服务器以端到端的形式进行的, 只有终端在激活态 下才能维持终端到 AAA服务器之间的端到端的链接,因此对于一个处于空闲 状态下的终端, 如果要进行重鉴权, 则必须退出空闲状态。 Since the terminal re-authentication is performed by the terminal and the Authentication, Authorization, Accounting (AAA) server in an end-to-end manner, only the terminal can maintain the end-to-end between the terminal and the AAA server in the active state. Link, so for a terminal that is in an idle state, if re-authentication is to be performed, the idle state must be exited.
终端处于空闲状态时, 只有终端自身和锚定鉴权器(或进一步包括锚定 寻呼控制器)这些网元中保存有终端的安全信息。
如果是终端触发对自身的重鉴权, 那么终端会发送测距请求消息 (RNGWhen the terminal is in an idle state, only the terminal itself and the anchor authenticator (or further including the anchor paging controller) retain the security information of the terminal in the network elements. If the terminal triggers re-authentication on itself, the terminal sends a ranging request message (RNG).
REQ )给优选基站, 退出空闲状态模式流程; 一旦终端退出空闲状态模式, 也就是重新入网, 即可对终端鉴权(也可以认为是重鉴权) , 该鉴权过程依 靠现有技术就可以完成。 REQ) to the preferred base station, exiting the idle state mode flow; once the terminal exits the idle state mode, that is, re-entering the network, the terminal can be authenticated (which can also be considered as re-authentication), and the authentication process can rely on the prior art. carry out.
如果是网络侧网元触发对终端的重鉴权, 则网络侧需要通知终端退出空 闲状态, 从而使终端在网络重入的过程中进行重鉴权。 现有技术中, 有两种 流程涉及到网络侧网元和终端的交互, 一个是寻呼流程, 另外一个是位置更 新。 If the network side network element triggers the re-authentication of the terminal, the network side needs to notify the terminal to exit the idle state, so that the terminal performs re-authentication in the process of network re-entry. In the prior art, there are two processes involved in the interaction between the network side network element and the terminal, one is a paging process, and the other is a location update.
图 1是现有技术中当有数据下发给终端时的寻呼流程, 具体步骤如下: 步骤 101 , 从家乡代理(Home Agent, 简称 HA ) 向锚定数据通道功能 FIG. 1 is a paging procedure in the prior art when data is sent to a terminal, and the specific steps are as follows: Step 101: From a Home Agent (HA) to anchor data channel function
( Anchor Data Path Function, 简称 Anchor DPF ) 以及相关联的外地代理 ( Foreign Agent, 简称 FA )发送下行数据。 外地代理 FA和 Anchor DPF总是 驻留在同一个接入业务网络网关( ASN GW )上, 因此通常用 Anchor DPF/FA 表示。 锚定数据通道功能和外地代理緩存此下行数据。 (Anchor Data Path Function, referred to as Anchor DPF) and the associated Foreign Agent (FA) send downlink data. The foreign agent FA and Anchor DPF always reside on the same Access Service Network Gateway (ASN GW) and are therefore usually represented by Anchor DPF/FA. The anchor data channel function and the foreign agent cache this downstream data.
步骤 102 , 锚定数据通道功能判断终端处于空闲状态, 向锚定寻呼控制 器(Anchor PC ) 以及相关联的位置寄存器( Location Register, 简称 LR )发 送开始寻呼请求消息( Initiate Paging Request ) ,请求锚定寻呼控制器( Anchor PC )寻呼终端, 以便激活终端使其接收数据。 位置寄存器是一个分布式数据 库 ,每个 Anchor PC都有一个 LR, 因此釆用 Anchor PC/LR表示。开始寻呼请 求消息中包含寻呼终端的必要信息。 Step 102: The anchor data channel function determines that the terminal is in an idle state, and sends an Initiate Paging Request message to the Anchor Paging Controller (Anchor PC) and an associated Location Register (LR). A request is made to anchor the paging controller (Attach PC) to terminate the terminal to activate the terminal to receive data. The location register is a distributed database, and each Anchor PC has an LR, so it is represented by Anchor PC/LR. The start paging request message contains the necessary information for the paging terminal.
步骤 103 , Anchor PC/LR 向 Anchor DPF/FA发送开始寻呼响应消息 ( Initiate Paging Response ) , 一方面用于确认在 Anchor PC/LR中该终端的信 息是否正确, 一方面用于确认这个终端是否授权被寻呼。 Step 103: The Anchor PC/LR sends an Initiate Paging Response message to the Anchor DPF/FA, which is used to confirm whether the information of the terminal is correct in the Anchor PC/LR, and is used to confirm whether the terminal is Authorization is paged.
步骤 104, 如果此终端已被授权寻呼, 则 Anchor PC/LR构造寻呼通告 ( Paging Announce )消息, 根据网络拓朴情况(拓朴已知 /拓朴未知)向以下 网元中的一个或多个发送寻呼通告消息: 中继寻呼控制器 (Relay PC)、 本地寻 呼控制器(Local PC ) 、 基站。 Step 104: If the terminal has been authorized to page, the Anchor PC/LR constructs a paging advertisement (Paging Announce) message, according to the network topology (topology unknown/topology unknown) to one of the following network elements or A plurality of paging advertisement messages are sent: a relay paging controller (Relay PC), a local paging controller (Local PC), and a base station.
步骤 105 ,本地寻呼控制器 ( Local PC )和 /或中继寻呼控制器 ( Relay PC )
向基站发送寻呼通告消息; Step 105, a local paging controller (Local PC) and/or a relay paging controller (Relay PC) Sending a paging announcement message to the base station;
步骤 106, 基站通过空口发送寻呼广播消息 ( MOB— PAG- ADV ) ; 步骤 107 , 终端收到寻呼广播消息后, 开始位置更新或空闲模式退出流 程; 其中对于空闲模式退出流程, 即重入网流程,可能会进行鉴权的过程(该 鉴权过程也可以认为是重鉴权过程) 。 Step 106: The base station sends a paging broadcast message (MOB_PAG-ADV) through the air interface. Step 107: After receiving the paging broadcast message, the terminal starts a location update or an idle mode exit process; where the idle mode exits the process, that is, re-enters the network. Process, the process of authentication may be performed (this authentication process can also be considered as a re-authentication process).
在上述流程图中, 其中逻辑网元 Local PC、 Relay PC、 Anchor PC/LR, Anchor DPF/FA都是驻留在物理网元 ASN-GW上,逻辑网元的 ID( Anchor PC ID, Anchor ASN GW ID, Authenticator ID )就是其驻留的物理网元的 ID ( ASN-GW ID ) 。 In the above flowchart, the logical network element Local PC, Relay PC, Anchor PC/LR, Anchor DPF/FA are all resident on the physical network element ASN-GW, and the ID of the logical network element (Anchor PC ID, Anchor ASN) The GW ID, Authenticator ID) is the ID (ASN-GW ID) of the physical network element on which it resides.
图 2是现有技术中终端进行位置更新的流程图, 具体步骤如下 2 is a flow chart of a location update of a terminal in the prior art, and the specific steps are as follows:
步骤 201 , 终端向当前优选基站(或称为服务基站)发送测距请求消息 ( RNG REQ ) , 请求位置更新, 请求消息中有锚定寻呼控制器的标识。 Step 201: The terminal sends a ranging request message (RNG REQ) to the current preferred base station (or the serving base station) to request a location update, where the request message has an identifier of the anchor paging controller.
步骤 202, 服务基站向当前服务接入网网关 ( Serving ASN GW )发送位 置更新请求(LU-Req ); 当前服务接入网网关上驻留有本地寻呼控制器; 步骤 203 , 当前服务接入网 ( Serving ASN ) 向锚定寻呼控制器发送位置 更新请求; 如果锚定寻呼控制器驻留在当前服务网关, 则不需要步骤 203; 当前服务接入网也可能经过一个或多个中继接入网网关发送到锚定寻呼控制 器。 Step 202: The serving base station sends a location update request (LU-Req) to the current serving access network gateway (Serving ASN GW); the local paging controller resides on the current serving access network gateway; Step 203, current service access Serving ASN sends a location update request to the anchor paging controller; if the anchor paging controller resides at the current serving gateway, step 203 is not required; the current serving access network may also pass one or more The access network gateway is sent to the anchor paging controller.
步骤 204, 锚定寻呼控制器和锚定鉴权器交互, 锚定寻呼控制器从锚定 鉴权器获取终端的鉴权密钥上下文( Authentication Key Context ) ; 如果锚定 寻呼控制器和锚定鉴权器驻留在同一个物理实体上, 则为步骤 204为内部交 互。 Step 204: The anchor paging controller interacts with the anchor authenticator, and the anchor paging controller acquires the authentication key context (Authentication Key Context) of the terminal from the anchor authenticator; if the anchor paging controller is anchored And the anchor authenticator resides on the same physical entity, then step 204 is an internal interaction.
步骤 205, 锚定寻呼控制器获取到 AK Context后, 向服务网关 ( Serving ASN GW )发送位置更新响应消息 (LU-Rsp), 其中包含有 AK Context; Step 205, after the anchor paging controller obtains the AK Context, sends a location update response message (LU-Rsp) to the serving gateway (Serving ASN GW), where the AK Context is included;
步骤 206 , 服务网关向服务基站发送位置更新响应消息; Step 206: The serving gateway sends a location update response message to the serving base station.
步骤 207, 服务基站向终端发送测距响应消息 (RNG RSP ) ; 该消息可 以包含如下指示信息至少之一: 位置更新成功、 位置更新失败、 有下行数据
发送。 Step 207: The serving base station sends a ranging response message (RNG RSP) to the terminal; the message may include at least one of the following indication information: location update success, location update failure, and downlink data Send.
步骤 208, 服务基站向服务网关发送位置更新确认 (LU Cnf); Step 208: The serving base station sends a location update confirmation (LU Cnf) to the serving gateway.
步骤 209, 服务网关向 Anchor PC发送位置更新确认; Anchor PC更新终 端空闲状态信息, 特别是当前的位置信息。 同 203类似, 如果锚定寻呼控制 器驻留在当前服务网关, 则不需要步骤 209; 当前服务接入网也可能经过一 个或多个中继接入网网关发送到锚定寻呼控制器。 Step 209: The service gateway sends a location update confirmation to the Anchor PC; the Anchor PC updates the terminal idle state information, in particular the current location information. Similar to 203, if the anchor paging controller resides at the current serving gateway, step 209 is not required; the current serving access network may also be sent to the anchor paging controller via one or more relay access network gateways. .
步骤 210, 如果 Anchor PC在收到 LU Cnf消息中基于加密的消息鉴权码 密钥( Cipher-based Message Authentication Code CMAC Key,简称 CMAC Key ) 有更新, 则 Anchor PC通知锚定鉴权器进行 CMAC Key Count更新。 Step 210: If the Anchor PC updates the Cipher-based Message Authentication Code (CMAC Key) in the received LU Cnf message, the Anchor PC notifies the anchor authenticator to perform CMAC. Key Count update.
从图 1可知, 当终端处于空闲状态时, 只有当 Anchor DPF/FA有数据要 发送给终端时, 才发送开始寻呼请求给锚定寻呼控制器 (步骤 101〜步骤 103 , 即为有数据下发时触发 Anchor PC进行寻呼) , 让锚定寻呼控制器开始寻呼 终端, 指示终端退出空闲模式(步骤 104到步骤 107 , 即 Anchor PC进行的寻 呼流程, 即为通用的寻呼流程) 。 现有技术中未提供以其它方式触发终端退 出空闲模式以便进行后续 (重)鉴权或接收下行数据等过程的方案。 As can be seen from FIG. 1, when the terminal is in an idle state, only when the Anchor DPF/FA has data to send to the terminal, the start paging request is sent to the anchor paging controller (steps 101 to 103, that is, there is data. When the delivery is triggered, the Anchor PC is triggered to perform paging, and the anchor paging controller starts paging the terminal, and instructs the terminal to exit the idle mode (steps 104 to 107, that is, the paging process performed by the Anchor PC, that is, the universal paging. Process) . The prior art does not provide a solution for triggering the terminal to exit the idle mode in other ways for subsequent (re)authentication or receiving downlink data.

For example, the anchor authenticator can send indication information to the anchor paging controller either directly or through an anchor data channel. The specific implementation may be: the anchor paging controller obtains the indication information from the message sent by the anchor authenticator, or obtains the indication message from the message forwarded by the anchor data channel function, and then anchors the paging controller to pass The paging process notifies the terminal in the idle state to exit the idle state. The message sent directly by the anchor authenticator to the anchor paging controller and the message that the anchor authenticator forwards through the anchor data channel function may be a start paging message, or other may be used to anchor the authenticator and anchor A message that communicates between paging controllers.

终端进行网络重入, 对终端发起寻呼, 对终端进行重鉴权, 有下行数据发送 给终端。 典型的指示信息是对终端进行重鉴权。 The indication information includes at least one of the following information: performing a location update, and the terminal exits the idle state, The terminal performs network re-entry, initiates paging to the terminal, re-authenticates the terminal, and sends downlink data to the terminal. A typical indication is to re-authenticate the terminal.
实施例二: Embodiment 2:
实施例二中釆用终端位置更新流程对终端重鉴权进行触发。 In the second embodiment, the terminal re-authentication right is triggered by the terminal location update process.
触发空闲状态的终端进行重鉴权的方法包括: 锚定鉴权器需要对处于空 闲状态下的终端进行重鉴权时, 将指示信息发送至锚定寻呼控制器, 锚定寻 呼控制器从锚定鉴权器获知用于触发重鉴权的指示信息后, 利用终端位置更 新流程指示终端退出空闲状态, 终端在退出空闲状态后在重新接入网络的过 程中进行(重)鉴权。 在本实施例中, 指示信息是用于触发重鉴权的指示信 息。 The method for triggering the re-authentication of the terminal in the idle state includes: the anchor authenticator needs to send the indication information to the anchor paging controller when re-authenticating the terminal in the idle state, and anchor the paging controller from After the anchor authenticator learns the indication information for triggering the re-authentication right, the terminal is used to indicate that the terminal exits the idle state by using the terminal location update procedure, and the terminal performs (re)authentication in the process of re-accessing the network after exiting the idle state. In this embodiment, the indication information is indication information for triggering re-authentication.

当 Anchor DPF/FA收到锚定鉴权器发送的开始寻呼请求消息后, 如果发 现该终端处于空闲模式, 则从该终端的上下文信息中找到该终端的 Anchor PC/LR驻留的 ASN-GW ID (也称为 Anchor PC ID ) , 然后向该 ASN GW ID 发送开始寻呼请求消息。 After the Anchor DPF/FA receives the start paging request message sent by the anchor authenticator, if the terminal is found to be in the idle mode, the ASN of the Anchor PC/LR resident of the terminal is found from the context information of the terminal. The GW ID (also known as the Anchor PC ID) then sends a Start Page Request message to the ASN GW ID.

具体实施例三: Specific embodiment 3:
具体实施例三详细描述实施例二中通过终端位置更新流程完成触发的过 程。 当锚定鉴权器需要对空闲模式下的终端进行重鉴权时, 发送指示信息给 锚定寻呼控制器, 锚定寻呼控制器通过终端位置更新流程指示终端退出空闲 模式在网络重入的过程中进行鉴权。 The third embodiment describes in detail the process of completing the triggering by the terminal location update process in the second embodiment. When the anchor authenticator needs to re-authenticate the terminal in the idle mode, the indication information is sent to the anchor paging controller, and the anchor paging controller instructs the terminal to exit the idle mode in the network re-entry through the terminal location update procedure. The process is authenticated.
从图 2可知, 现有的终端位置更新流程是用于终端触发位置更新之用。 但是这个流程可以进一步改动, 在位置更新的同时, 进一步发送其它指示信 息给终端用来指示终端退出空闲模式; 终端接收到对应的指示信息后, 进行 空闲模式退出, 在网络重入过程中对终端进行(重)鉴权。 As can be seen from FIG. 2, the existing terminal location update procedure is used for terminal trigger location update. However, the process may be further modified. At the same time as the location update, the terminal further sends other indication information to the terminal to indicate that the terminal exits the idle mode. After receiving the corresponding indication information, the terminal performs idle mode exit, and the terminal is in the network re-entry process. Perform (re)authentication.
当锚定鉴权器需要进行重鉴权时, 发送指示信息给锚定寻呼控制器; 即 锚定寻呼控制器在发送位置更新响应消息 (图 2的步骤 205 )之前收到锚定 鉴权器发送的指示信息(如图 4中步骤 401或图 5的步骤 502 ) , 或者在图 2 的步骤 204中从锚定鉴权获知指示信息。 锚定寻呼控制器通过位置更新流程 将指示信息通知到终端。 终端收到指示信息后, 退出空闲状态, 在重入网的 过程中进行(重)鉴权。 When the anchor authenticator needs to perform re-authentication, the indication information is sent to the anchor paging controller; that is, the anchor paging controller receives the anchor authentication before sending the location update response message (step 205 of FIG. 2) The indication information sent by the device (such as step 401 in FIG. 4 or step 502 in FIG. 5), or the indication information is obtained from the anchor authentication in step 204 of FIG. The anchor paging controller notifies the terminal of the indication information through the location update procedure. After receiving the indication information, the terminal exits the idle state and performs (re)authentication in the process of re-entering the network.
在步骤 205-207 的消息中至少之一包括上述指示信息, 指示信息是以下
信息中的至少一个: 终端退出空闲状态, 终端进行网络重入, 对终端发起寻 呼, 对终端进行重鉴权, 有下行数据发送给终端, 位置更新结果。 典型的指 示信息是对终端进行重鉴权。 At least one of the messages in steps 205-207 includes the above indication information, and the indication information is the following At least one of the information: the terminal exits the idle state, the terminal performs network re-entry, initiates paging to the terminal, re-authenticates the terminal, and sends downlink data to the terminal, and the location update result. A typical indication is to re-authenticate the terminal.
本发明还提供了一种触发空闲状态的终端进行下行数据接收的方法。 现 有技术中, 锚定数据通道功能有下行数据要发送给空闲状态的终端时, 一般 釆用寻呼流程使终端退出空闲状态后进行下行数据的接收。 如图 1所示, 寻 呼流程中寻呼控制器 (锚定寻呼控制、 中继寻呼控制器和本地寻呼控制器中 的一个或多个) 向寻呼组中的大量基站发送寻呼通告消息, 而寻呼组收到寻 呼通道消息的大量基站通过空口发送寻呼广播消息去寻呼终端, 而终端位置 更新流程中, 只需要终端与当前优选基站进行通讯即可。 所以, 本发明釆用 终端位置更新流程触发空闲状态的终端退出空闲状态以进行下行数据接收, 可以节省了网络侧和空口资源的开销。 The present invention also provides a method for triggering downlink data reception by a terminal that triggers an idle state. In the prior art, when the anchor data channel function has downlink data to be sent to the idle state terminal, the paging process is generally used to enable the terminal to exit the idle state and then receive the downlink data. As shown in FIG. 1, the paging controller (one or more of the anchor paging control, the relay paging controller, and the local paging controller) in the paging process sends a search to a large number of base stations in the paging group. The paging message is sent, and a large number of base stations that receive the paging channel message by the paging group send the paging broadcast message to the paging terminal through the air interface, and in the terminal location update process, only the terminal needs to communicate with the current preferred base station. Therefore, the terminal in the terminal location update process triggers the idle state to exit the idle state for downlink data reception, which can save the network side and air interface resource overhead.
本发明中, 锚定数据通道功能有下行数据要发送给终端时, 利用位置更 新流程指示终端退出空闲模式以接收下行数据。 此方法具体包括: 锚定数据 通道功能有下行数据需要下发至终端时,将指示信息发送至锚定寻呼控制器, 锚定寻呼控制器触发空闲状态的终端退出空闲状态以进行下行数据的接收。 In the present invention, when the anchor data channel function has downlink data to be sent to the terminal, the location update process is used to instruct the terminal to exit the idle mode to receive the downlink data. The method specifically includes: anchoring the data channel function, when the downlink data needs to be sent to the terminal, sending the indication information to the anchor paging controller, and the anchor paging controller triggers the idle state terminal to exit the idle state to perform downlink data. Reception.
本方法中, 指示消息是用于触发接收下行数据的指示消息。 In the method, the indication message is an indication message for triggering receiving downlink data.
从图 2可知, 现在位置更新流程是用于终端触发位置更新用的。 但是这 个流程可以进一步改动, 在位置更新的同时, 进一步用来指示有下行数据发 送给终端。 终端接收到对应的指示后退出空闲模式, 终端退出空闲模式, 即 重新入网后, 就可以接收下行数据。 As can be seen from Figure 2, the location update process is now used for terminal trigger location update. However, this process can be further modified to further indicate that downlink data is sent to the terminal while the location is being updated. After receiving the corresponding indication, the terminal exits the idle mode, and the terminal exits the idle mode, that is, after re-entering the network, the downlink data can be received.
当 Anchor DP/FA有数据要发送给终端时,发送指示信息给锚定寻呼控制 器; 即锚定寻呼控制器在发送位置更新响应消息 (图 2的步骤 205 )之前收 到锚定数据通道发送的指示信息 (如图 1 中步骤 102 ) , 锚定寻呼控制器可 以通过位置更新流程将指示信息通知到终端; 终端收到指示信息后, 退出空 闲模式, 然后终端重新进入网络接收下行数据。 When the Anchor DP/FA has data to send to the terminal, the indication information is sent to the anchor paging controller; that is, the anchor paging controller receives the anchor data before transmitting the location update response message (step 205 of FIG. 2). The indication information sent by the channel (step 102 in FIG. 1), the anchor paging controller may notify the terminal to the terminal through the location update process; after receiving the indication information, the terminal exits the idle mode, and then the terminal re-enters the network to receive the downlink. data.

在上述发明的方法和实施例中, Anchor DPF和 Anchor DF的功能是等价 的。 In the method and embodiment of the above invention, the functions of the Anchor DPF and the Anchor DF are equivalent.
以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本 领域的技术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和 原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护 范围之内。 The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention.
