技术领域
本公开涉及移动通信技术领域，具体涉及一种配置寻呼区的方法、基站、和核心网节点及计算机可读存储介质。
背景技术
长期演进(LTE，Long Term Evolution)技术中，空闲态用户设备(UE，也被称为终端)的寻呼流程中，当核心网节点，如移动性管理实体(MME，Mobility Management Entity)收到服务网关(SGW，Serving GateWay)的下行数据通知后，发送寻呼消息给UE的跟踪区(TA，Tracking Area)列表内的基站，其中MME发给基站的寻呼消息中可以携带UE的寻呼区列表。
当UE处于一种特殊状态，例如轻连接状态或去激活状态时，UE与基站之间无线资源控制(RRC，Radio Resource Control)连接被释放或被挂起，但基站仍然保留UE的上下文，UE的无线接入网(RAN，Radio Access Network)侧行为类似空闲态，而核心网还处于连接态。此时，如果有下行数据到达，MME不会触发寻呼流程，SGW继续发送数据到基站，而由基站触发寻呼流程。然而，此时基站通常并没有UE的寻呼区配置信息，相关技术对这种情况下基站如何进行寻呼也没有提供明确的解决方案。
发明内容
本公开实施例要解决的技术问题是提供一种配置寻呼区的方法、基站、核心网节点及计算机可读存储介质，为终端配置用于基站所发起寻呼的寻呼区配置信息，使得基站可以直接寻呼处于特殊状态下的终端。

所述第一基站将所述第一终端的第一寻呼配置信息发送给所述第一终端。
本公开实施例还提供了另一种配置寻呼区的方法，包括：

本公开实施例还提供了一种核心网节点，包括：处理器和用于存储能够在处理器上运行的计算机程序的存储器，其中，所述处理器用于运行所述计 算机程序时，执行上述核心网节点侧的配置寻呼区的方法。
本公开实施例还提供了一种计算机可读存储介质，其上存储有计算机程序，其中，该计算机程序被处理器执行时实现上述基站侧的配置寻呼区的方法。
本公开实施例还提供了一种计算机可读存储介质，其上存储有计算机程序，其中，该计算机程序被处理器执行时实现上述核心网节点侧的配置寻呼区的方法。
与相关技术相比，本公开实施例提供的配置寻呼区的方法、基站、核心网节点及计算机可读存储介质，至少具有以下有益效果：
为终端配置用于基站所发起寻呼的寻呼区配置信息，使得基站可以直接寻呼处于特殊状态下的终端。
从以上方法可以看出，本公开实施例为终端配置的新的寻呼区，该寻呼区用于基站所发起的寻呼，从而使得基站在终端进入特殊状态(轻连接态或去激活态)时，可以直接基于该寻呼区发起对终端的寻呼。另外，由于基站可以比核心网更为准确的跟踪终端的位置，因此可以为终端配置相对于传统核心网寻呼区范围较小的上述寻呼区，进而可以减少寻呼开销，提高寻呼效率。

本公开实施例中，源基站是终端当前服务小区所属的基站，即终端当前驻留的基站；目标基站是终端通过小区重选选择出的基站，即终端将要驻留到的目标小区所属的基站。在本公开的实施例中，所述基站的形式不限，可以是宏基站(Macro Base Station)、微基站(Pico Base Station)、Node B(3G移动基站的称呼)、增强型基站(eNB)、家庭增强型基站(Femto eNB或Home eNode B或Home eNB或HeNB)、中继站、接入点、RRU(Remote Radio Unit，远端射频模块)、RRH(Remote Radio Head，射频拉远头)、传输点等。

本公开实施例中，所述核心网节点是位于核心网侧的节点，例如，具体可以是MME。当然，随着标准的发展和变化，该节点可能具有不同的名称。以下实施例中将以核心网节点为MME为例进行说明。需要指出的是，对于基于不同标准的通信系统，该节点也可能是核心网侧的其他设备。
根据不同的标准定义，跟踪区和寻呼区有着类似的概念，通常用于表示核心网可以发起寻呼的区域。本文中将跟踪区和寻呼区也可以统一表述为寻呼区。
请参照图1，本公开实施例提供的配置寻呼区的方法，应用于第一基站时，包括以下步骤：
步骤11，第一基站在本地保存第一终端的第一寻呼配置信息，其中，所述第一寻呼配置信息包含有第一寻呼区的信息，所述第一寻呼区属于第一类寻呼区，所述第一类寻呼区为用于基站所发起寻呼的寻呼区。
步骤12，所述第一基站将所述第一终端的第一寻呼配置信息发送给所述第一终端。
本实施例在以上步骤中，在基站和终端侧为终端配置了一种新的寻呼区(第一类寻呼区)，该寻呼区是用于基站所发起的寻呼的。而相关技术中寻呼通常是由移动性管理实体(MME)发起的，MME所使用的寻呼区是用于核心网所发起寻呼的跟踪区，在本文中将此类寻呼区称作第二类寻呼区。也就是说，本实施例在相关技术中的核心网所使用的跟踪区(第二类寻呼区)的基础上，进一步为终端配置了用于基站所发起寻呼的寻呼区(第一类寻呼区)，使得基站可以根据第一类寻呼区直接发起寻呼。例如，在第一类寻呼区的范围小于第二类寻呼区时，基于第一类寻呼区发起的寻呼，通常更能有效的寻呼到终端，减少寻呼开销。
具体的，在上述步骤12之后，如果基站检测到终端的网络连接状态进入特殊状态，这里的特殊状态可以是轻连接态或去激活态，也可以称为第一状态，此时基站如果接收到该终端的下行数据，则可以根据本地保存的所述第一寻呼配置信息，在所述第一寻呼区内寻呼所述第一终端。该寻呼流程中，基站发起寻呼，并使用第一类寻呼区进行寻呼。
作为寻呼所述第一终端的一种实现方式，第一基站可以同时在本基站范围内寻呼第一终端，以及，向第一寻呼区内除本基站外的各个其他基站发送针对第一终端的寻呼消息。该方式中，第一寻呼区内的所有基站都发起对第一终端的寻呼，从而能够及时寻呼到第一终端。
作为寻呼所述第一终端的另一种实现方式，第一基站可以先在本基站范围内寻呼第一终端，并在寻呼未收到响应后，再向第一寻呼区内除本基站外的各个其他基站发送针对第一终端的寻呼消息。该方式可以在一定程度上减少基站的寻呼开销。
这里，第一基站发送给其他基站的寻呼消息中，通常需要携带有第一终端的终端标识。另外，所述寻呼消息还可以携带有第一寻呼区的全部寻呼区域或者所述全部寻呼区域中归属于所述其他基站的部分寻呼区域，所述寻呼区域包括寻呼区列表，寻呼区列表中的每个寻呼区可以包括一个或多个基站、传输点和小区。在寻呼消息中仅携带其他基站的部分寻呼区域时，可以降低寻呼消息的负荷，减少基站间需要传输的数据量。
本文中，所述第一寻呼配置信息具体可以是由核心网节点为所述终端生成并配置的，此时第一基站可以从核心网节点获得所述第一寻呼区配置信息。所述第一寻呼区配置信息还可以是由第一基站预先建立的自配置寻呼区域，还可以是预先通过OAM方式配置的第一基站的寻呼配置信息。
在上述步骤11之前，第一基站可以进一步获得第一终端的第一寻呼配置信息，根据第一寻呼配置信息的不同的生成方式，第一基站可以有多种对应的获得第一寻呼配置信息方式。
例如，在第一寻呼配置信息是核心网节点为所述终端生成并配置的场景下，第一基站可以在第一终端的接入流程中，接收核心网节点发送的所述第一寻呼配置信息，所述第一寻呼区是核心网为第一终端配置的寻呼区域。这里的接入流程包括初始附着流程。此时，所述第一寻呼区配置信息携带在寻呼区传输消息或初始上下文建立请求消息中，所述第一基站进一步通过解析核心网节点发送的寻呼区传输消息或初始上下文建立请求消息，得到所述第一寻呼配置信息。
又例如，在第一寻呼配置信息是第一基站预先建立的自配置寻呼区域的场景下，第一基站可以在第一终端的接入流程中，基于预先建立的所述第一基站的自配置寻呼区域，得到所述第一终端的第一寻呼区配置信息，所述第一基站的自配置寻呼区域包括所述第一基站下的寻呼区域或者包括第一基站及第一基站的一个以上的相邻基站下的寻呼区域。这里的第一基站下的寻呼区域可以包括第一基站下的全部或部分寻呼区域，例如，包括第一基站的一个或多个或全部的小区。第一基站及第一基站的一个以上的相邻基站下的寻呼区域可以包括第一基站下的全部或部分寻呼区域，以及所述相邻基站的全部或部分寻呼区域。通常，寻呼区域包括寻呼区列表，每个寻呼区包括一个 或多个基站、传输点和小区。
这里，所述第一基站可以预先通过基站间接口，与相邻基站协商，从而建立第一基站的自配置寻呼区域，或者是在通过OAM方式配置的场景下，第一基站可以预先接收通过OAM方式配置的本基站的寻呼配置信息，得到第一基站的自配置寻呼区域。
另外，在上述步骤12之后，第一基站还可以向核心网节点发送所述第一终端的第一寻呼配置信息，以与核心网节点同步所述第一终端的寻呼配置。
关于上述过程中的传输第一寻呼配置信息的具体消息，具体可以是：第一基站可以将所述第一终端的第一寻呼配置信息，携带在连接建立完成消息或连接重配置请求消息中发送给所述第一终端；将所述第一终端的第一寻呼配置信息，携带在初始UE消息或初始上下文建立响应消息中发送给所述核心网节点。
与相关技术类似的，第一基站还可以在核心网发起的寻呼过程中寻呼第一终端，例如，第一基站在接收第一核心网节点发送的第一终端的寻呼消息时，根据所述寻呼消息寻呼所述第一终端，其中，所述寻呼消息包含有某个寻呼区的信息，该寻呼区属于第二类寻呼区，所述第二类寻呼区为用于核心网所发起寻呼的寻呼区。该寻呼流程中，寻呼是核心网发起的，核心网在发送给基站的寻呼消息中携带第二类寻呼区，基站在发起寻呼时使用第二类寻呼区进行寻呼。
在第一终端接收到第一基站发送的第一寻呼配置信息之后，第一终端可能关机或移出所述第一基站的覆盖范围，导致第一终端的第一类寻呼区失效或更新，例如，其他基站为第一终端重新配置了新的第一类寻呼区时。本公开实施例还针对这种情况进行相应的配置信息的释放处理，以节约基站的相关资源。
例如，第一基站接收所述核心网节点发送的第一释放请求消息，并根据所述第一释放请求消息，释放本地保存的所述第一终端的第一寻呼配置信息。
又例如，第一基站接收第二基站发送的第二释放请求消息，并根据所述第二释放请求消息，释放本地保存的所述第一终端的第一寻呼配置信息。
上述第一、第二释放请求消息，用于通知第一基站释放第一终端的第一 类寻呼区的配置信息(第一寻呼配置信息)，上述第一、第二释放请求消息可以携带第一终端的终端标识，以指示需要处理的终端。
类似的，当某个终端(假设为第二终端)从其他基站移动至第一基站，假设该第二终端已经配置了第二寻呼区(源寻呼区)，所述第二寻呼区属于第一类寻呼区，第二终端可以通过寻呼区更新请求对上述源寻呼区进行更新，以获得第一基站为其配置的新的第一类寻呼区。
此时，针对由核心网节点为终端生成第一类寻呼区的场景，具体可以包括以下步骤：第一基站可以接收第二终端发送的用于请求寻呼区更新的第一消息，所述寻呼区更新请求携带有作为源寻呼区的第二寻呼区，所述第二寻呼区属于第一类寻呼区；第一基站向核心网节点发送用于请求更新第二终端寻呼区的第二消息，并接收核心网节点返回的携带有第三寻呼区的第二寻呼配置信息，所述第三寻呼区是核心网为第二终端配置的寻呼区域，且属于第一类寻呼区；第一基站在本地保存所述第二终端的第二寻呼区配置信息，并将所述第二寻呼区配置信息发送给所述第二终端。
上述流程中，所述第一消息具体可以为寻呼区更新请求消息或连接建立完成消息；所述第二消息为初始UE消息。所述第一基站进一步从核心网节点发送的初始上下文请求消息中，接收所述第二寻呼配置信息；所述第一基站进一步通过寻呼区更新回复消息、连接重配置消息或下行信息传输消息，将所述第二寻呼区配置信息发送给所述第二终端。
针对由基站为终端生成第一类寻呼区的场景，具体可以包括以下步骤：第一基站接收第三终端发送的用于请求寻呼区更新的第三消息，所述寻呼区更新请求携带有第四寻呼区，所述第四寻呼区属于第一类寻呼区；第一基站基于预先建立的所述第一基站的自配置寻呼区域，或者基于预先通过OAM方式配置的本基站的寻呼配置信息，获得所述第三终端的第三寻呼区配置信息，所述第一基站的自配置寻呼区域包括所述第一基站及第一基站的一个以上的相邻基站；第一基站在本地保存所述第三终端的第三寻呼配置信息，并将所述第三寻呼区配置信息发送给所述第三终端和核心网节点。
下面进一步介绍本实施例所述配置寻呼区方法中的核心网节点。
核心网节点可以同步保存所述终端的第一寻呼配置信息，如图2所示， 本实施例提供的配置寻呼区的方法，应用于第一核心网节点时，包括以下步骤：
步骤21，第一核心网节点获得所述第一终端的第一寻呼区配置信息，所述第一寻呼配置信息包含有第一寻呼区的信息，其中，所述第一寻呼区属于第一类寻呼区，所述第一类寻呼区为用于基站所发起寻呼的寻呼区；所述第一核心网节点为第一终端当前驻留的第一基站归属的核心网节点。
步骤22，第一核心网节点在本地保存所述第一终端的第一寻呼配置信息。
针对由核心网节点为终端生成第一类寻呼区的场景，上述步骤21中，第一核心网节点进一步在所述第一终端的接入流程中，为所述第一终端配置第一类寻呼区，从而得到所述第一寻呼配置信息。在上述步骤22之后，第一核心网节点还可以向所述第一基站发送所述第一终端的第一寻呼配置信息，另外第一核心网节点还可以经由第一基站向第一终端发送所述第一终端的第一寻呼配置信息。
针对由基站为终端生成第一类寻呼区的场景，上述步骤21中，第一核心网节点接收所述第一终端当前驻留的第一基站发送所述第一终端的第一寻呼配置信息，该第一寻呼配置信息可以是第一基站的自组织寻呼区或预先基于OAM方式配置的寻呼区。
当第一终端移出第一基站的覆盖范围，导致第一终端的第一类寻呼区失效或更新，例如，其他基站为第一终端重新配置了新的第一类寻呼区时。本公开实施例还针对这种情况进行相应的配置信息的释放处理，以节约基站的相关资源。此时，若第一核心网节点接收第二核心网节点发送的指示消息，所述指示消息用于指示第二核心网节点已保存有所述第一终端新配置的寻呼区，所述新配置的寻呼区属于所述第一类寻呼区，则第一核心网节点向所述第一基站发送释放请求消息，所述释放请求消息用于指示释放所述第一终端的第一寻呼配置信息。
类似的，当某个终端(如第二终端)从其他基站移动至第一基站，在该第二终端已经配置了第二寻呼区(源寻呼区)，所述第二寻呼区属于第一类寻呼区时，第二终端可以通过寻呼区更新请求对上述源寻呼区进行更新，以获得第一基站为其配置的新的第一类寻呼区。
此时，若由第一核心网节点为第二终端生成第一类寻呼区，则可以包括以下步骤：第一核心网节点接收第一基站发送的用于请求更新第二终端寻呼区的第二消息，所述第二消息携带有第二终端的第二寻呼区，所述第二寻呼区属于第一类寻呼区；第一核心网节点为所述第二终端配置属于第一类寻呼区的第三寻呼区，获得并保存所述第二终端的第二寻呼配置信息；第一核心网节点将所述第二终端的第二寻呼配置信息发送给所述第一基站。
类似的，当某个终端(如第三终端)从其他基站移动至第一基站，若由第一基站为第三终端生成第一类寻呼区(如第一基站的自配置寻呼区域或预先OAM配置的寻呼区域)，则可以包括以下步骤：第一核心网节点接收并保存第一基站发送的第三终端的第三寻呼配置信息，所述第三寻呼区配置信息是第一基站为第三终端新配置的第一类寻呼区。
从以上方法可以看出，本公开实施例为终端配置的新的寻呼区，该寻呼区用于基站所发起的寻呼，从而使得基站在终端进入特殊状态(轻连接态或去激活态)时，可以直接基于该寻呼区发起对终端的寻呼。另外，由于基站可以比核心网更为准确的跟踪终端的位置，因此可以为终端配置相对于相关技术中核心网寻呼区范围较小的上述寻呼区，进而可以减少寻呼开销，提高寻呼效率。

下面进一步结合本实施例的配置寻呼区的方法的若干整体的流程示例，对以上方法作进一步的描述。
图5给出了本实施例的配置寻呼区的方法的一个示例，该示例中由核心网节点为终端生成第一类寻呼区：
在步骤51中，第一终端通过与第一基站进行交互，初始建立第一终端的RRC连接。
在步骤52中，第一基站向第一MME发送第一终端支持的特殊状态，如轻连接态和/或去激活态等，具体的，第一基站可以在初始UE消息中携带UE支持的特殊状态/UE类型信息，以通知给第一MME。
在步骤53～56中，在第一终端的初始附着流程中，第一基站向第一MME发送附着请求消息，第一MME为所述第一终端配置第一类寻呼区，得到所述第一寻呼配置信息，第一MME与服务网关/分组数据网络网关(SGW/PGW)进行修改会话请求/响应(modify session request/modify session response)交互，以及，第一MME经由第一基站向第一终端发送附着请求接受消息，第一基站将该附着请求接受消息转发给第一终端。该附着请求接受消息、携带有第一终端的第一寻呼配置信息。第一终端接收到该附着请求接受消息，保存其 中携带的第一寻呼配置信息。
这里，所述第一寻呼配置信息包含有第一寻呼区的信息，其中，所述第一寻呼区属于第一类寻呼区，所述第一类寻呼区为用于基站所发起寻呼的寻呼区。第一MME还可以在上述附着请求接受消息中同时携带用于核心网发起寻呼的寻呼区(第二类寻呼区)，如相关技术中的跟踪区(TA)列表。
在步骤57中，第一MME向第一基站发送所述第一终端的第一寻呼配置信息，具体可以将第一寻呼配置信息携带在寻呼区传输消息进行发送；第一基站接收并保存所述第一终端的第一寻呼配置信息。
以上流程中，第一MME通过步骤55～56、步骤57中的两个消息将第一寻呼配置信息通知给第一基站和第一终端。
图6给出了本实施例的配置寻呼区的方法的又一个示例，该示例中也是由核心网节点为终端生成第一类寻呼区，不同的是，该示例中第一MME仅通过一个消息，即实现了将第一寻呼配置信息通知给第一基站和第一终端。
在步骤61中，第一终端通过与第一基站进行交互，初始建立第一终端的RRC连接。
在步骤62中，第一基站向第一MME发送第一终端支持的特殊状态，如轻连接态和/或去激活态等，具体的，第一基站可以在初始UE消息中携带UE支持的特殊状态/UE类型信息，以通知给第一MME。
在步骤63～64中，第一MME与服务网关/分组数据网络网关(SGW/PGW)进行修改会话请求/响应(modify session request/modify session response)交互。
在步骤65中，第一MME为所述第一终端配置第一类寻呼区，得到所述第一寻呼配置信息，并且，第一MME发送给第一终端的初始上下文建立请求消息中携带第一终端的第一寻呼配置信息。第一基站接收解析所述初始上下文建立请求消息，获得其中携带的第一终端的第一寻呼配置信息并保存。
这里，所述第一寻呼配置信息包含有第一寻呼区的信息，其中，所述第一寻呼区属于第一类寻呼区，所述第一类寻呼区为用于基站所发起寻呼的寻呼区。第一MME还可以在上述初始上下文建立请求消息中同时携带用于核心网发起寻呼的寻呼区(第二类寻呼区)，如相关技术中的跟踪区(TA)列表。
步骤66，第一基站向第一终端发送第一终端的第一寻呼配置信息，具体的，第一基站可以将第一终端的第一寻呼配置信息携带在RRC连接重配消息中发送，这里，该RRC连接重配消息中也可以携带第二类寻呼区，如TA列表。第一终端获得第一寻呼配置信息并保存。
在步骤67～69中，第一终端与第一基站继续进行RRC重连接配置过程，并在重配置完成后，第一基站与第一终端可以交互数据。
图7给出了本实施例的配置寻呼区的方法的另一个示例，该示例中由第一基站为终端生成第一类寻呼区，具体的，第一基站可以通过与周边相邻基站通过站间接口进行协商，建立自组织寻呼区域；或者，预先通过OAM方式配置第一基站的寻呼区域。第一终端的初始接入流程包括以下步骤：
在步骤701～704中，第一终端通过与第一基站进行交互，初始建立第一终端的RRC连接。其中，在步骤703中，第一基站向第一终端发送RRC连接建立(RRC connection setup)消息。
在步骤705中，第一基站向第一MME发送第一终端支持的特殊状态，如轻连接态和/或去激活态等，具体的，第一基站可以在初始UE消息中携带UE支持的特殊状态/UE类型信息，以通知给第一MME。
在步骤706～707中，第一MME与服务网关/分组数据网络网关(SGW/PGW)进行修改会话请求/响应(modify session request/modify session response)交互。
在步骤708中，第一MME向第一基站发初始上下文建立请求消息。
在步骤709中，第一基站向第一终端发送RRC连接重配置消息。
在步骤710中，第一终端向第一基站发送RRC连接重配置完成消息。
在步骤711中，第一基站向第一MME发送初始上下文建立响应消息。
在步骤712中，第一终端可以与第一基站交互数据。
在以上的终端初始接入流程中，第一基站可以基于预先建立的所述第一基站的自配置寻呼区域，或者，预先通过OAM方式配置的本基站的寻呼配置信息，得到所述第一终端的第一寻呼区配置信息，然后利用上述步骤703或者步骤709的消息，将所述第一终端的第一寻呼区配置信息发送给第一终端，利用上述步骤705或步骤711的消息，将所述第一终端的第一寻呼区配 置信息发送给第一MME。
图8给出了当第一终端发生寻呼区间的移动时的示例，这里的寻呼区间的移动是指在第一类寻呼区间的移动，即第一终端从第一类寻呼区的一个寻呼区(下文中称为第一寻呼区)移动至另一寻呼区(下文中称为第二寻呼区)。假设第一终端由第一寻呼区的第一基站，移动至第二寻呼区的第二基站，第一MME和第二MME分别为第一基站和第二基站归属的MME。假设图8所示场景中也是由核心网节点(MME)为终端生成第一类寻呼区。
在步骤81～82中，当第一终端移动出从第一寻呼区移动至第二寻呼区，或者预先设置的寻呼区周期更新超时时，第一终端进行寻呼区更新，通过当前驻留的第二基站向第二MME发送寻呼区更新请求，其中携带作为源寻呼区的第一寻呼区的信息。第二基站可以通过初始UE消息向第二MME发送上述寻呼区更新请求。
在步骤83中，第二MME确定第二终端的新的第一类寻呼区(第二寻呼区)，发送初始上下文请求消息到第二基站，其中携带的寻呼区更新回复中包含新寻呼区(第二寻呼区)，第二基站接收后保存该第一终端的第二寻呼区的信息，具体可以保存在在UE上下文中；
在步骤84中，第二基站发送寻呼区更新回复到第一终端，其中携带新寻呼区(第二寻呼区)的信息，第一终端接收后保存。
图9给出了当第一终端发生寻呼区间的移动时的又一示例，这里的寻呼区间的移动是指在第一类寻呼区间的移动，即第一终端从第一类寻呼区的一个寻呼区(下文中依然称为第一寻呼区)移动至另一寻呼区(下文中依然称为第二寻呼区)。假设第一终端由第一寻呼区的第一基站，移动至第二寻呼区的第二基站，第一MME和第二MME分别为第一基站和第二基站归属的MME。假设图9所示场景中依然是由核心网节点(MME)为终端生成第一类寻呼区。
在步骤91～92中，当第一终端移动出从第一寻呼区移动至第二寻呼区，或者预先设置的寻呼区周期更新超时时，第一终端进行寻呼区更新，通过第二基站发送寻呼区更新请求到第二MME，具体可以通过RRC连接建立完成消息发送上述寻呼区更新请求。第二基站可以通过初始UE消息向第二MME 发送上述寻呼区更新请求。上述寻呼区更新请求携带源寻呼区(第一寻呼区)，还可以携带源TA，以进行TA更新。
在步骤93中，第二MME确定第二终端的新的第一类寻呼区(第二寻呼区)，发送初始上下文请求消息到第二基站，其中携带的寻呼区更新回复中包含新寻呼区(第二寻呼区)和新TA，第二基站接收后保存该第一终端的第二寻呼区的信息，具体可以保存在在UE上下文中；当然，第二基站还可以保存新TA的信息，具体可以保存在在UE上下文中。
在步骤94中，第二基站发送RRC连接重配置/下行信息传输消息到第一终端，其中携带第二寻呼区，还可以携带新TA的信息，从而第二终端接收后保存第二寻呼区，还可以保存新TA的信息。
图10给出了当第一终端发生寻呼区间的移动时的另一示例，这里的寻呼区间的移动是指在第一类寻呼区间的移动，即第一终端从第一类寻呼区的一个寻呼区(下文中依然称为第一寻呼区)移动至另一寻呼区(下文中依然称为第二寻呼区)。假设第一终端由第一寻呼区的第一基站，移动至第二寻呼区的第二基站，第一MME和第二MME分别为第一基站和第二基站归属的MME。假设图10所示场景中是由基站(第二基站)为终端生成第一类寻呼区。
在步骤101中，当第一终端移动出从第一寻呼区移动至第二寻呼区，或者预先设置的寻呼区周期更新超时时，第一终端进行寻呼区更新，向第二基站发送寻呼区更新请求，其中携带源寻呼区(第一寻呼区)，具体可以通过RRC连接建立完成消息发送上述寻呼区更新请求。这里，第一终端还可以在RRC连接建立完成消息中携带源TA，以进行TA更新。
在步骤102～103中，第二基站向第二MME发送初始UE消息，在初始UE消息携带源TA的信息，以请求第二MME进行TA更新；第二MME进行TA更新，确定新TA，并可以通过初始上下文请求消息携带所述新TA的信息，发送给第二基站。
在步骤104中，第二基站基于自组织寻呼区域或预先OAM配置的寻呼区域，为第一终端配置新的第一类寻呼区(称为第二寻呼区)，并通过发送RRC连接重配置/下行信息传输消息到第一终端，其中携带第二寻呼区，还可 以携带新TA的信息，从而第二终端接收后保存第二寻呼区，还可以保存新TA的信息。
在步骤105中，第二基站将所述第二终端的第二寻呼区的信息发送给第二MME，第二MME接收并保存所述第二终端的第二寻呼区的信息。
需要指出的是，为了突出本公开实施例的改进点，以上图5～10中，省略了一些相关技术的初始附着流程中的已有消息的传输。
综上，本公开实施例提供的上述方法及装置，为终端配置的新的寻呼区，该寻呼区用于基站所发起的寻呼，从而使得基站在终端进入特殊状态(轻连接态或去激活态)时，可以直接基于该寻呼区发起对终端的寻呼。
请参照图11，本公开另一实施例提供的配置寻呼区的方法，应用于第一基站时，包括以下步骤：
步骤11a，第一基站接收第一MME发送的第一终端的第一寻呼配置信息，所述第一基站是第一终端当前驻留的基站，所述第一MME是第一基站归属的MME。
这里，所述第一寻呼配置信息是第一MME在第一终端建立网络连接过程中或建立网络连接后，为第一终端配置的第一寻呼区的配置信息。
作为一种实现方式，第一MME可以将第一终端的第一寻呼配置信息，携带在初始上下文建立请求消息中发送给第一基站。第一基站解析该初始上下文建立请求消息，得到其中携带的所述第一终端的第一寻呼配置信息。所述第一寻呼配置信息具体可以包括寻呼周期和/或第一寻呼区的寻呼区域，寻呼区域可以通过寻呼区列表来表示，每个寻呼区可以包括一个或多个基站、传输点和小区。
这里，第一寻呼配置信息可以是第一MME在第一终端初次建立RRC连接过程中或者初次建立RRC连接后，为第一终端配置的第一寻呼区的配置信息；第一寻呼配置信息还可以是重新建立RRC连接过程中或者重新建立RRC连接后，第一MME为第一终端配置的第一寻呼区的配置信息。
步骤12a，第一基站在本地保存所述第一终端的第一寻呼配置信息。
通过以上步骤，本公开实施例在第一终端初次建立RRC连接时，在第一终端当前驻留的第一基站处保存了第一MME为第一终端配置的第一寻呼配 置信息，从而后续在第一终端进入第一状态时，第一基站可以根据本地保存的第一寻呼配置信息，寻呼第一终端，使得基站能够在合适的区域内寻呼处于轻连接状态或去激活状态的终端，避免了终端的数据发生丢失，改善了用户的使用体验。
在上述步骤12a之后，第一基站可以据本地保存的第一寻呼配置信息，寻呼第一终端。另外，第一基站和终端还可以根据所述寻呼周期，计算具体的寻呼发送时隙。
本公开实施例中，所述第一状态包括轻连接态或去激活状态。假设第一终端进入了轻连接态或去激活状态，此时当核心网需要向第一终端发送数据时，将直接向第一基站发送第一终端的下行数据，此时，为实现对第一终端的寻呼，在上述步骤12a之后，第一基站还可以在接收到核心网节点，如服务网关发送给第一终端的下行数据时，根据本地保存的所述第一终端的第一寻呼配置信息，在第一终端所属的第一寻呼区内寻呼所述第一终端。
作为一种实现方式，本公开实施例中，第一基站在第一终端所属的第一寻呼区内寻呼所述第一终端，可以是：第一基站在本基站范围内寻呼第一终端，以及，向第一寻呼区内除本基站外的各个其他基站发送寻呼消息，以使其他基站根据该寻呼消息寻呼所述第一终端。该方式中，第一寻呼区内的所有基站都发起对第一终端的寻呼，从而能够及时寻呼到第一终端。
作为另一种实现方式，本公开实施例中，第一基站在第一终端所属的第一寻呼区内寻呼所述第一终端，还可以是：第一基站在本基站范围内寻呼第一终端，并在寻呼失败后，向第一寻呼区内除本基站外的各个其他基站发送寻呼消息。该方式中，第一基站首先在第一寻呼区中归属于第一基站的部分寻呼区域内寻呼第一终端，当寻呼失败时，才继续向第一寻呼区的其他基站发送寻呼消息，控制各个其他基站在第一寻呼区中归属于该其他基站的部分寻呼区域内寻呼第一终端。该方式可以在一定程度上减少基站的寻呼压力。
这里，第一基站发送给其他基站的寻呼消息中，通常需要携带有第一终端的终端标识。另外，所述寻呼消息还可以携带有第一寻呼区的全部寻呼区域或者所述全部寻呼区域中归属于所述其他基站的部分寻呼区域，所述寻呼区域包括寻呼区列表，每个寻呼区包括一个或多个基站、传输点和小区。在 寻呼消息中仅携带其他基站的部分寻呼区域时，可以降低寻呼消息的负荷，减少基站间需要传输的数据量。
下面结合图12，介绍本实施例中的配置寻呼区的方法，在应用于第一MME时的流程，如图12所示，包括以下步骤：
步骤21a，第一MME在第一终端建立网络连接过程中或建立网络连接后，为所述第一终端配置第一寻呼区，得到第一寻呼配置信息，其中，所述第一MME为第一终端当前驻留的第一基站归属的MME。
这里，第一MME可以将所述第一寻呼配置信息，携带在初始上下文建立请求消息中，发送给所述第一基站。所述网络连接可以是RRC连接。
步骤22a，第一MME将所述第一终端的第一寻呼配置信息，发送给所述第一基站。
通过以上步骤，第一MME将为第一终端配置的第一寻呼配置信息发送给第一基站，使得第一基站后续可以在第一终端进入轻连接态或去激活状态时，直接根据第一寻呼配置信息发起对第一终端的寻呼，避免了终端的数据发生丢失，改善了用户的使用体验。
图13进一步给出了本实施例的配置寻呼区的方法的一个完整的流程示例：
在步骤31中，第一终端通过与第一基站进行交互，初始建立第一终端的RRC连接。
在步骤32中，第一基站向第一MME发送第一终端支持的特殊状态，如轻连接态和/或去激活态等，具体的，第一基站可以在初始UE消息中携带UE支持的特殊状态/UE类型信息，以通知给第一MME。
在步骤33～34中，第一MME与服务网关/分组数据网络网关(SGW/PGW)进行修改会话请求/响应(modify session request/modify session response)交互。
在步骤35中，第一MME为第一终端配置第一寻呼区，获得第一寻呼配置信息，向第一基站发送初始上下文建立请求消息，该消息中携带有第一终端的终端标识以及第一寻呼配置信息。第一基站接收到该消息后，在本地保存第一终端的第一寻呼配置信息。第一寻呼配置信息可以包含一个或多个传输点/小区/基站。
在步骤36～38中，第一终端与第一基站进行RRC重连接配置过程，并在配置完成后，第一基站与第一终端可以交互数据。
此后，如果第一终端进入特殊状态(本文中的特殊状态是指轻连接态或去激活态)，当第一基站收到SGW发送的所述第一终端的下行数据时，一种寻呼方式为：第一基站发送寻呼消息到该第一寻呼区内的各个其他基站，其中寻呼消息中包含第一终端的终端标识，还包含第一寻呼区的全部寻呼区域或者第一寻呼区中其他基站的寻呼区域(如该其他基站下的传输点/小区)；另一种寻呼方式为第一基站先在第一寻呼区中本第一基站的寻呼区域内寻呼第一终端，若寻呼失败，再发送上述寻呼消息到该第一寻呼区内的各个其他基站。
如前述实施例所述，第一基站作为第一终端的驻留基站，保存了第一终端的第一寻呼配置信息。后续第一终端可能进入轻连接态或去激活状态，还可能发生移动。当第一终端移出第一寻呼区的范围时，例如，当第一终端通过小区重选，从第一寻呼区内的第一基站或其他基站，驻留到第一寻呼区外的第二基站，第一终端在检测到第二基站不在第一寻呼区范围内时，将会发起寻呼区更新过程。下面将介绍当第一终端发生跨寻呼区的移动时第一基站和第一MME侧的处理流程。
请参照图14，本公开实施例在第一终端发生跨寻呼区的移动，移动至第一寻呼区外的第二基站时，所述第一基站还可以执行以下步骤：
步骤41a，第一基站接收第一MME发送的第一释放请求消息，所述第一释放请求消息是第一MME在确定第二MME已为第一终端配置了第二寻呼区后发送的。
这里，第一终端移动至第二基站后发起寻呼区更新过程，在该寻呼区更新过程中，第二基站所属的第二MME将为第一终端配置新的寻呼区(以下称为第二寻呼区)，获得第二寻呼配置信息。第二MME在为第一终端配置了第二寻呼区后，将通知第一MME。第一MME接收到第二MME的通知后，可以向第一基站发送用于指示释放第一终端的寻呼配置信息的第一释放请求消息，该消息中可以携带有第一终端的终端标识。
步骤42a，第一基站根据所述第一释放请求消息，释放本地保存的所述第 一终端的寻呼配置信息。
这里，第一终端根据第一释放请求消息，删除本地保存的第一终端的寻呼配置信息，以节约第一基站的相关资源。
以上提供了第一基站释放第一终端的寻呼配置信息的一种实现方式，该实现方式中由第一MME指示第一基站执行释放处理。本公开实施例还可以采用另外一种实现方式，该实现方式由第二基站通过基站间接口，直接指示第一基站执行上述释放处理，具体为：第一基站接收第二基站发送的第二释放请求消息，所述第二释放请求消息是第二基站获得了第二MME为第一终端配置的第二寻呼配置信息后发送的；然后，第一基站根据所述第二释放请求消息，释放本地保存的所述第一终端的寻呼配置信息。
请参照图15，本公开实施例在第一终端发生跨寻呼区的移动，移动至第一寻呼区外的第二基站时，所述第一MME还可以执行以下步骤：
步骤51a，第一MME接收第二MME发送的指示消息，所述指示消息用于指示第二MME已为处于第一状态的第一终端配置了第二寻呼区，所述第一状态为轻连接态或去激活状态。
步骤52a，第一MME向所述第一基站发送释放请求消息，所述释放请求消息用于指示释放所述第一终端的第一寻呼配置信息。
这里，释放请求消息携带了第一终端的终端标识，以使第一基站释放对应终端的寻呼配置信息。
以上步骤实现了由第一MME来通知第一基站释放第一终端的寻呼配置信息。
由于网络中包括多个终端，假设第二终端处于第一状态，且第二终端发生跨寻呼区移动，移动到了第一MME下的某个基站(如第一基站或其他基站)，并通过小区重选驻留到了该基站。此时第二终端发现寻呼区发生了更新或者预设的寻呼区更新周期到达，则将发起寻呼区更新过程，此时第一MME还可以执行以下步骤：第一MME在接收到处于第一状态的第二终端的寻呼区更新请求消息后，为第二终端配置对应的第三寻呼区，得到第三寻呼配置信息，然后，第一MME将所述第二终端的第三寻呼配置信息，发送给所述第二终端当前驻留的基站。
图16进一步给出了本实施例的配置寻呼区的方法的一个完整的流程示例：
这里，假设第一终端由第一寻呼区内的第一基站，移动至第一寻呼区外的第二基站，第一MME和第二MME分别为第一基站和第二基站归属的MME。
在步骤61a～62a中，处于第一状态的第一终端，在检测到寻呼区发生变化或者在预设的寻呼区更新周期到达时，通过当前驻留的第二基站向第二MME发起寻呼区更新请求，该寻呼区更新请求中携带有第一终端当前的源寻呼区(即第一寻呼区)的信息。
在步骤63a～64a中，第二MME为第一终端配置新的寻呼区(第二寻呼区)，得到第二寻呼配置信息，并向源寻呼区对应的第一MME发送通知消息，以通知所述第一终端的寻呼区发生了更新。
在步骤65a～66a中，第二MME向第二基站发送携带有第二寻呼配置信息的初始上下文请求消息，第二基站据此获得并在本地保存第一终端的第二寻呼配置信息，并且第二基站向第一终端返回寻呼区更新回复消息，该消息中携带有第二寻呼配置信息，从而第一终端获得新的寻呼区的配置信息。
为了释放第一基站保存的第一终端的第一寻呼配置信息，图16中提供了两种不同的实现方式，其中一种是在步骤67a中，由第二基站直接向第一基站发送寻呼区释放请求消息；另一种是在步骤67b中，由第一MME向第一基站发送寻呼区释放请求消息。第一基站接收到上述寻呼区释放请求消息，释放本地保存的第一终端的寻呼配置信息。
如前述实施例所述，第一基站作为第一终端的驻留基站，保存了第一终端的第一寻呼配置信息。后续第一终端可能进入轻连接态或去激活状态，还可能发生移动。当第一终端在第一寻呼区内移动时，例如，当第一终端通过小区重选，从第一寻呼区内的第一基站，驻留到第一寻呼区内的第三基站，为保证第一终端的数据传输可靠性，此时需要更新第一终端的核心网转发路径。下面将介绍当第一终端发生寻呼区内的移动时第一MME和第一基站侧的处理流程。
请参照图17，本公开实施例在第一终端发生寻呼区内的移动，从第一寻 呼区内的第一基站，移动至第一寻呼区内的第三基站时，所述第一MME还可以执行以下步骤：
步骤71，第一MME接收第三基站发送的用于更新所述第一终端的核心网转发路径的请求消息，所述请求消息是第三基站从第一基站获得了所述第一终端的寻呼配置信息后发送的，所述第三基站和第一基站分别为处于第一状态的第一终端小区重选的目标基站和源基站，所述第一状态为轻连接态或去激活状态。
这里，第三基站在从源基站(第一基站)处获得了第一终端的寻呼配置信息后，发起核心网转发路径的更新过程，向第一MME发送更新所述第一终端的核心网转发路径的请求消息。
步骤72，第一MME根据所述请求消息，向对应的核心网节点发起第一终端的核心网转发路径的更新过程，并在更新完成后向第三基站返回响应消息。
这里，第一MME根据所述请求消息进行第一终端的核心网转发路径更新，包括更新第一终端的锚点基站为第三基站等处理，该更新过程可以参考相关技术的实现，此处不再赘述。
通过以上步骤，更新了第一终端的核心网转发路径，从而当核心网有去往第一终端的下行数据时，可以将该下行数据发送给第三基站，通过第三基站发起对第一终端的寻呼过程。
请参照图18，本公开实施例在第一终端发生寻呼区内的移动，从第一寻呼区内的第一基站，移动至第一寻呼区内的第三基站时，所述第一基站还可以执行以下步骤：
步骤81a，第一基站接收第三基站发送的用于请求第一终端的寻呼配置信息的第一寻呼区请求消息，所述第一寻呼区请求消息是第三基站检测到处于第一状态的第一终端从第一基站小区重选到本第三基站后发送的，所述第三基站与第一基站归属于同一寻呼区。
步骤82a，第一基站将本地保存的所述第一终端的第一寻呼配置信息，发送给第三基站。
通过以上步骤，当处于第一状态的第一终端，在同一寻呼区内发生移动 时，可以通过基站间的交互，在第一终端当前驻留的基站处保存第一终端的寻呼配置信息。
在上述步骤82a之后，第一基站还可以释放本地保存的所述第一终端的第一寻呼配置信息，或者，等待接收第三基站发送的第三释放请求消息，并在接收到所述第三释放请求消息后，释放本地保存的所述第一终端的第一寻呼配置信息，其中，所述第三释放请求消息是第三基站在更新了所述第一终端的核心网转发路径后发送的。
由于网络中包括多个终端，假设第二终端处于第一状态，且第二终端发生寻呼区内的移动，并通过小区重选过程，从第四基站驻留到第一基站，假设第四基站与第一基站归属于同一寻呼区，此时所述第一基站还可以执行以下步骤：
第一基站检测到处于第一状态的第二终端从第四基站驻留到本第一基站后，向第四基站发送用于请求第二终端的寻呼配置信息的第二寻呼区请求消息，并接收第四基站返回的第二终端的寻呼配置信息，并在本地保存第二终端的寻呼配置信息；然后，第一基站向第一MME发送用于更新所述第二终端的核心网转发路径的请求消息，并接收第一MME在所述第二终端的核心网转发路径更新后返回的响应消息。
另外，第一基站还可以通知第四基站释放第一终端的寻呼配置信息，具体的，第一基站可以在接收到所述第四基站返回的第二终端的寻呼配置信息后，或者在接收到第一MME返回的所述响应消息后，向第四基站发送用于请求释放所述第二终端的寻呼配置信息的第四释放请求消息。
图19进一步给出了本实施例的配置寻呼区的方法的一个完整的流程示例：
这里，假设处于第一状态的第一终端，通过小区重选，从第一寻呼区内的第一基站，驻留到第一寻呼区内的第三基站。
在步骤91a中，当第一终端从第一基站移动并驻留到第三基站，第三基站向第一基站请求获取该第一终端的寻呼配置信息，例如发送寻呼区请求消息或发送第一终端上下文请求消息，上述消息中携带第一终端的终端标识，该第一终端的终端标识在第一寻呼区内唯一。
在步骤92a中，第一基站将本地保存的第一终端的寻呼配置信息，发送给第三基站，或发送第一终端的上下文到第三基站，其中第一终端上下文中携带第一终端的寻呼配置信息(如寻呼区/寻呼区列表)。具体的，第一基站可以发送寻呼区传输消息或发送第一终端上下文传输消息，其中携带第一终端的终端标识和该第一终端的寻呼配置信息。第三基站从第一基站返回的消息中获取第一终端的寻呼配置信息，并在本地进行保存，具体的，可以保存在第一终端的上下文中。作为一种可选动作，在本步骤中，第一基站还可以释放该第一终端的寻呼配置信息。
在步骤93a～96a中，第三基站发送核心网转发路径更新过程，在该更新过程中，将更新第一终端的锚点基站为本第三基站。具体的，第三基站发送核心网转发路径更新请求消息到第一MME以发起更新过程，其中该消息中携带第一终端标识。
若上述步骤92a中，第一基站未执行释放该第一终端的寻呼配置信息的动作，则该流程还可以包括一个可选步骤97a，在步骤97a中，第三基站在更新了所述第一终端的核心网转发路径后，向第一基站发送第一终端的寻呼区释放请求消息，第一基站在接收到该寻呼区释放请求消息后，释放本地保存的所述第一终端的寻呼配置信息。
