图 2为本发明实施例提供的一种寻呼终端的方法流程图。 本实施例提 供的方法适用于多层无线网络和单层无线网络。 如图 1所示， 本实施例提 供的方法包括：
步骤 21： 核心网网元获取终端的移动信息或者业务信息。
核心网网元可以是多层或单层无线网络中的核心网网元，例如 SGSN , 也可以是单层无线网络中的核心网网元， 例如 MME。 移动信息是表示终 端移动情况的信息。 示例性的， 可以是终端的位置信息， 也可以是终端接 入小区的变化次数等信息。 位置信息包括终端所在的小区的信息或者基站 的信息； 获取终端的移动信息的方法可以是： 核心网网元接收终端连接的 无线接入网元发送的终端的位置信息， 并保存接收到的位置信息。 获取终 端的移动信息的方法也可以是， 当终端释放与无线接入网元的无线连接 时， 核心网网元接收无线接入网元发送的终端的位置信息并保存接收到的 位置信息。
业务信息可以是终端的业务类型、业务名称或业务的 QoS值等和终端 所要进行的业务相关的信息， 这里终端所要进行的业务为引起核心网发起 此次寻呼的业务。 通常情况下， 为终端部署业务后， 核心网侧的归属用户 月良务器 （ Home Subscriber Server, HSS )保存有终端的相关信息和为终端 部署的业务的信息，核心网网元可从 HSS中获取到终端的业务信息。另夕卜， 也可以由数据网关、 或报文解析功能实体等网元， 根据预设的协议对终端 的交互消息进行业务解析， 将解析后的业务信息上报给核心网。
步骤 22:核心网网元根据终端的移动信息以及移动信息与寻呼范围的 对应关系，确定终端的寻呼范围； 或者，核心网网元根据终端的业务信息， 以及业务信息与寻呼范围的对应关系， 确定终端的寻呼范围； 寻呼范围包 括： 单个小区、 单个基站、 多个小区、 多个基站或位置区。
核心网网元确定寻呼范围有多种方法。
示例性的， 其中一种方法是根据终端的移动信息以及移动信息与寻呼 范围的对应关系， 确定终端的寻呼范围。 核心网网元保存有终端的移动信 息与寻呼范围的对应关系。 当核心网网元需寻呼终端时， 在保存的移动信 息与寻呼范围的对应关系中， 查找与获取的该终端的移动信息对应的寻呼 范围。
可选地， 终端的移动信息与寻呼范围的对应关系包括： 终端的移动信 息与移动特性的对应关系以及终端的移动特性与寻呼范围的对应关系。 其 中， 终端的移动特性包括： 低移动状态， 中移动状态或者高移动状态。 核 心网网元根据终端的移动信息以及移动信息与移动特性的对应关系， 获取 终端的移动特性。 之后， 根据终端的移动特性以及移动特性与寻呼范围的 对应关系， 确定终端的寻呼范围。 另外， 终端也可以直接向移动管理网元 上报自己的移动特性， 而不需要由移动管理网元根据获取的终端的移动信 息和保存的移动信息与移动特性的对应关系， 确定终端的移动特性。 举例 来说， 移动特性与寻呼范围的对应关系包括： 若移动特性为低移动状态， 寻呼范围为单个小区或者单个基站； 或者， 若移动特性为中移动状态， 寻 呼范围为多个小区或者多个基站； 或者， 若移动特性为高移动状态， 寻呼 范围为位置区。
示例性的， 核心网网元确定寻呼范围的另一种方法是根据终端的业务 信息， 以及业务信息与寻呼范围的对应关系， 确定终端的寻呼范围。 核心 网网元可以保存有业务信息与寻呼范围的对应关系， 也可以从其它网元获 取业务信息与寻呼范围的对应关系。 核心网网元需要寻呼终端时， 根据获 取的终端的业务信息和业务信息与寻呼范围的对应关系， 确定寻呼范围。
可选地， 业务信息与寻呼范围的对应关系， 包括： 业务信息与业务特 性的对应关系以及业务特性和寻呼范围的对应关系； 业务特性包括： 时延 敏感业务或者时延不敏感业务。 核心网网元根据终端的业务信息以及业务 信息与业务特性的对应关系， 获取终端的业务特性。 之后， 根据终端的业 务特性以及业务特性与寻呼范围的对应关系， 获取终端的寻呼范围。 若终 端的业务为时延敏感的业务， 例如， 语音业务， 核心网网元确定终端的寻 呼范围为终端所在的位置区。
示例性的， 核心网网元确定寻呼范围的另一种方法是， 根据终端的业 务信息， 确定终端的业务特性， 如果终端的业务特性为时延不敏感业务， 根据终端的移动信 , 以及移动信息与寻呼范围的对应关系， 确定终端的寻 呼范围， 如果终端的业务特性为时延敏感业务， 根据终端的业务信息， 以 及业务信息与寻呼范围的对应关系， 确定终端的寻呼范围。 若终端的业务 特性为时延不敏感业务时， 例如 HTTP业务， 核心网网元根据终端的移动 信息与移动信息与寻呼范围的对应关系， 确定终端的寻呼范围为单个小 区。
在上述方法中， 若寻呼范围为单个小区， 表示在终端最后连接的小区 内寻呼终端， 多个小区表示在终端最后连接的小区和终端最后连接的小区 的相邻小区内寻呼终端。 寻呼范围为单个基站表示终端最后连接的基站在 覆盖的所有小区内寻呼终端。 寻呼范围为多个基站。 表示终端最后连接的 基站在覆盖的所有小区内寻呼终端， 并且终端最后连接的基站的相邻基站 也在覆盖的所有小区内寻呼终端。 若寻呼范围为位置区， 表示位置区内的 所有基站在覆盖的所有小区内寻呼终端。 其中， 终端最后连接的小区为终 端释放无线连接之前接入的小区， 相应地终端最后连接的基站为终端释放 无线连接之前接入的基站。 具体地， 终端最后连接的基站， 可以是该终端 在释放与无线接入网元的无线连接时， 向核心网网元上报该终端所在小区 的信息或所在的基站的信息的基站。
步骤 23 : 核心网网元根据终端的寻呼范围， 寻呼终端。
如果核心网网元是多层无线网络中的核心网网元， 核心网网元向终端 最后连接的接入网控制器寻呼终端， 即释放无线连接之前接入的接入网控 制器， 发送寻呼消息， 接入网控制器根据寻呼消息再向寻呼范围内的基站 发送寻呼消息， 使基站在特定范围内寻呼终端。
如果核心网网元是单层无线网络中的核心网网元， 核心网网元向寻呼 范围内的基站发送寻呼消息， 使基站在特定范围内寻呼终端。
本发明实施例提供的方法， 核心网网元在寻呼终端时， 根据终端的移 动信息以及移动信息与寻呼范围的对应关系，确定终端的寻呼范围；或者， 核心网网元根据终端的业务信息， 以及业务信息与寻呼范围的对应关系， 确定终端的寻呼范围。 根据确定的寻呼范围寻呼终端。 由于根据移动信息 或者业务信息来确定寻呼终端的范围， 因此可以减少无关小区或基站的寻 呼处理， 节省网络资源。

在上述实施例中， 终端最后连接的基站， 可以是该终端在释放与无线 接入网元的无线连接时， 向核心网网元上报该终端所在小区的信息或所在 的基站的信息的基站。
