Description

一种本地呼叫本地交换的实现方法
技术领域
本发明涉及通信领域， 更具体地涉及电路域本地呼叫本地交换的实现方 法。
背景技术
全球移动通讯系统 ( Global System for Mobile communications, GSM )和 统一移动通讯系统 ( Universal Mobile Telecommunications System, UMTS )等 移动网络釆用电路交换技术， 称为电路（ Circuit Switched, 简称 CS )域， 能 够为用户提供基本的语音业务， 以及基于语音业务的补充业务。
在世界一些地方如非洲、 南美洲和南亚等地， 缺乏快速可靠的传输资源 或者高昂的传输成本， 给运营商在网络和业务部署带来一定的困难。 然而， 根据统计数据， 在那些地方， 移动网络中的大多数呼叫是本地呼叫， 这些呼 叫在相同的基站系统（Base Station System, BSS ) 下产生。 对于本地呼叫， 如果釆用本地交换技术（语音数据在 BSS进行环路）， 则可以节省了 BSS与 核心网移动交换中心 （ Mobile Switch Center, MSC ) 间 A口传输资源。
图 1是传统语音呼叫的示意图， 用户设备 ( User Equipment, UE )通过 电路域接入到 BSS和 MSC。 当 UE1呼叫 UE2时候， UE1通过 BSS向其接入 的 MSC发送呼叫建立请求； MSC根据 UE2接入的位置信息，找到被叫 UE2, 并通知 BSS建立与 UE1和 UE2相连的无线承载，并且分别建立 BSS与 MSC 间 UE1和 UE2的承载； MSC两侧承载进行环路，保证 UE1和 UE2间的语音 通讯。
图 2是釆用本地呼叫本地交换技术的语音呼叫的示意图， 与图 1相比， 当 MSC收到 UE1的呼叫建立请求，根据小区判断 UE1和 UE2是否同属一个 BSS,若 UE1和 UE2是同属一个 BSS,则 MSC通知 BSS执行本地交换； UE1 和 UE2的承载环路在 BSS侧执行，这样就省下了 BSS和 MSS间的承载资源。
图 3是图 2釆用本地呼叫本地交换技术的信令流程， 包括下面步骤： 301、 UE1和 UE2在相同的 BSS下发起呼叫， 并通过核心网 MSC建立 相互连接， MSC为主叫 UE1和被叫 UE2分配 BSS和 MSC间的电路号或者 呼叫标识；
302、被叫 UE2在振铃状态下应答，并经过 BSS向 MSC发送被叫应答消 息；
303、 MSC向主叫 UE1发送被叫应答消息， 通知 UE1呼叫接通；
304、 MSC根据主叫 UE1和被叫 UE2当前的位置信息， 判断本次呼叫是 否同属一个 BSS内的本地呼叫；
305、如果是同属一个 BSS内的本地呼叫， 则 MSC向 BSS发送本地交换 命令消息， 通知 BSS 进行本地交换， 本地交换命令消息中携带 301 步骤中
MSC为主叫 UE1和被叫 UE2分配的 BSS和 MSC间的电路号或者呼叫标识；
306、 BSS收到本地交换命令消息， 根据本地交换命令消息中的主、 被叫 的电路号或者呼叫标识， 关联到两个正在进行的通讯会话， 并对其语音数据 承载进行环路， 实现语音承载在 BSS内进行交换；
307、 本地交换成功后， BSS向 MSC发送本地交换成功消息；
308、 MSC收到本地交换成功消息后， 通知 BSS释放 BSS和 MSC间的 语音 7?ι载连接。 针对上述步骤分析， 如果在 BSS连接多个 MSC的场景下， 如图 4所示， 主叫 UE1通过 BSS接入到 MSC1 , 被叫 UE2通过 BSS接入到 MSC2, 主叫 和被叫虽然在同个 BSS下发起呼叫， 但主叫和被叫分别接入到不同的 MSC, 从而会导致 304 步骤中无论主叫 UE1接入的 MSC1 , 还是被叫 UE2接入的 MSC2 都无法根据主、 被叫的位置信息判断本次呼叫是否为本地呼叫， 最终 导致本地呼叫无法执行本地交换问题。
发明内容
