Description

一种基于 IMSI的寻呼方法及系统 技术领域
本发明 涉及通用移动通信系统 （ UMTS , Universal Mobile Telecommunications System )的寻呼技术， 尤其涉及一种基于国际移动用户 识别码 ( IMSI, International Mobile Subscriber Identity )的寻呼方法及系统。 背景技术
在 UMTS中，釆用 Iu灵活（Iu Flex )配置时，一个无线网络控制器（RNC, Radio Network Controller )可以同时连接多个移动交换中心（ MSC , Mobile Switching Center )。核心网没有 UE的临时识别码 ( TMSI, Temporary Mobile Subscriber Identity )信息时， CS域被叫 UE会釆用 IMSI寻呼， RNC需要 将被叫 UE的初始直传消息路由到发起寻呼的 MSC, 来保证此次寻呼的成 功， 如果 RNC将此被叫 UE的初始直传消息路由到非发起寻呼的 MSC, 将 会导致寻呼失败。
目前第三代合作伙伴计划 （ 3GPP, 3rd Generation Partnership Project ) 协议描述的 RNC给 IMSI寻呼的被叫 UE选择 MSC的方法如下：首先， UE 所注册的 MSC下发 IMSI寻呼消息，并携带自身的全局核心网标识（Global CN ID ) 以及被寻呼 UE的 IMSI, RNC接收并将 MSC的 Global CN ID以 及被寻呼 UE的 IMSI对应保存； 然后， UE接收到此寻呼消息后， 在原因 值为寻呼响应的初始直传消息 (Initial Direct Transfer)中携带域内非接入层节 点选择 ( IDN S , Intra Domain NAS Node Selector )信元， 且在此信元中， 表明釆用 IMSI寻呼方式、 以及路由参数 ( Routing parameter ) 的计算方法 为将 IMSI当作 10进制的自然数， 除以 10后， 再用 1000取余（ Decimal To Binary [(IMSI div 10) mod 1000] ); 最后， RNC从初始直传消息的 IDNNS 信元获知是 IMSI寻呼方式， 按照其中携带的路由参数计算方法， 计算出之 前保存的 IMSI对应的路由参数， 得到各路由参数与之前保存的 Global CN ID的对应关系， 然后在计算出的路由参数中， 查找与接收到的所述 IDN S 信元中携带的路由参数 ( Routing parameter )相同的路由参数， 如果找到相 同的路由参数， 则找到与该路由参数对应的 Global CN ID, 并将所述初始 直传消息发送给所找到 Global CN ID标识的 MSC, 寻呼成功， 否则， 不发 送所述初始直传消息， 寻呼失败。 但是， 这种方法对于不同 UE的 IMSI可 能会计算出相同的路由参数， 使得 RNC无法准确找到发起寻呼的 MSC的 Global CN ID, 从而导致寻呼失败， 因此， 该方法容易导致寻呼失败， 寻呼 成功率低。
例如， IMSI为 206201010000270的 UE— 1 目前注册在 MSC— 1 , IMSI 为 206201011000271的 UE— 2注册在 MSC— 5 , IMSI为 206201010300275的
UE 3注册在 MSC— 6。 核心网同时对这三个 UE发起 IMSI寻呼， UE— 1、 UE— 2、 UE— 3根据上述路由参数计算方法， 得到各自的路由参数均是 27, 则在发出的初始直传消息中均携带为该路由参数。按照上述寻呼方法， RNC 根据初始直传消息中的路由参数计算方法， 也会计算出三个均为 27的路由 参数， 这样， 由于路由参数均为 27, RNC根据路由参数进行匹配时， 无法 准确找出 UE— 1、 UE 2、 UE 3所分别注册的 MSC，因而无法将 UE— 1、 UE 2、 UE 3上报的初始直传消息发送给发起其寻呼的 MSC上， 最终导致后续寻 呼的失败。 发明内容
有鉴于此，本发明的主要目的在于提供一种基于 IMSI的寻呼方法及系 统， 以解决现有 IMSI寻呼方法成功率低的问题。

在上述方案中， 在所述 RNC接收被寻呼 UE发送的 IMSI之前， 所述 方法还包括： 所述 UE将自身的 IMSI携带在所述初始直传消息中， 发送给 所述 RNC。 在上述方案中， 所述 UE将自身的 IMSI携带在所述初始直传消息中， 具体为：所述 UE将所述初始直传消息中 NAS层消息连接管理服务请求 CM service request的移动标识设置为 IMSI。
本发明还提供了一种基于 IMSI的寻呼系统， 所述系统包括： 发起寻呼 的 MSC、 RNC以及被寻呼 UE,其中，所述 RNC包括接收单元和发送单元， 接收单元， 用于接收被寻呼 UE发送的 IMSI; 发送单元， 用于根据所述接 收单元接收到的 IMSI、 以及已保存的 IMSI与 MSC标识的对应关系， 将被 寻呼 UE发送的初始直传消息发送给发起寻呼的 MSC。
在上述方案中， 所述被寻呼 UE具体用于， 将自身的 IMSI携带在 RRC 连接请求消息中发送给所述 RNC; 或者， 将自身的 IMSI携带在所述初始 直传消息中发送给所述 RNC。
在上述方案中， 所述发起寻呼的 MSC 具体用于， 发起寻呼， 向所述 RNC发送携带有自身标识、以及被寻呼 UE的 IMSI的寻呼消息；所述 RNC 还包括： 存储单元， 用于接收所述 MSC发送的寻呼消息， 并保存所述寻呼 消息携带的 MSC标识与被寻呼 UE的 IMSI的对应关系。

实施例一
如图 2所示， 本实施例中基于 IMSI的寻呼方法， 具体可以包括以下流 程： 步骤 201 , MSC发起寻呼， 下发携带自身的 Global CN ID、 以及被寻 呼 UE的 IMSI的 CS域寻呼消息；
步骤 202, RNC接收所述寻呼消息， 将其中携带的 MSC的 Global CN ID、 与被寻呼 UE的 IMSI、 以及两者的对应关系保存， 并将所述寻呼消息 透传给被寻呼的 UE;
步骤 203 , 被寻呼的 UE接收所述寻呼消息， 在确定没有正确可用的 TMSI 时， 且所述寻呼消息确定所述寻呼的寻呼方式为 IMSI寻呼时， UE 在 RRC连接请求消息中携带初始 UE标识为 IMSI, RNC接收到该 RRC连 接请求消息后保存其中携带的被寻呼 UE的 IMSI。
步骤 204-206, UE与 RNC之间、 以及 RNC与 NodeB之间交互， 完成
RRC连接的建立过程。
步骤 207, UE发送原因值为寻呼响应的初始直传消息， 该初始直传消 息中携带 IDNNS信元， 表明釆用 IMSI方式、 以及路由参数的计算方法为 将 IMSI当作 10进制的自然数， 除以 10后， 再用 1000取余；
步骤 208, RNC接收 UE发送的初始直传消息，IDNNS路由方式为 IMSI 方式， 则在已保存的 IMSI与 Global CN ID的对应关系中， 查找到与所述 UE在 RRC连接请求消息中携带的 IMSI相同的 IMSI ,并找到与该 IMSI对 应的 Global CN ID, 将所述初始直传消息发送给所找到 Global CN ID标识 的 MSC, 即发起该寻呼的 MSC, 寻呼成功， 之后， UE就可以根据所找到 的 Global CN ID, 将自身的通信数据路由到该 MSC。
实施例二
如图 3所示， 本实施例中基于 IMSI的寻呼方法， 具体包括以下流程： 步骤 301-302: 与步骤 201-202完全相同；
步骤 303-306: 与步骤 203-206相同， 不同的是， UE在 RRC连接请求 消息中携带的初始 UE标识可能不为 IMSI,报文临时识别码（ PTMSI, Packet TMSI )存在时， 可以选择在此消息中携带的初始 UE标识为 PTMSI； 步骤 307: UE将原因值为寻呼响应的初始直传消息中 NAS层消息 CM service request的移动标识设置为 IMSI, 并向 RNC发送该初始直传消息， 携带 IDN S信元，表明釆用 IMSI方式、以及路由参数的计算方法为将 IMSI 当作 10进制的自然数， 除以 10后， 再用 1000取余；
步骤 308: IDNNS路由方式为 IMSI方式， 则 RNC在已保存的 IMSI 与 Global CN ID的对应关系中， 查找到与所述 UE在初始直传消息中 NAS 层消息 CM service request的移动标识中设置的 IMSI相同的 IMSI, 并找到 与该 IMSI对应的 Global CN ID , 将所述初始直传消息发送给所找到 Global CN ID所标识的 MSC , 即发起该寻呼的 MSC, 寻呼成功， 之后， UE就可 以根据所找到的 Global CN ID , 将自身的通信数据路由到该 MSC。
