Description

管理用户资源的方法、MSC及系统 技术领域
本申请涉及通信技术领域，例如涉及一种管理用户资源的方法、MSC及系统。
背景技术
LTE(Long Term Evolution，长期演进)是由3GPP(The 3rd Generation Partnership Project，第三代合作伙伴计划)组织制定的UMTS(Universal Mobile Telecommunications System，通用移动通信系统)技术标准的长期演进。LTE网络回落到CDMA(Code Division Multiple Access，码分多址)2000组网示意图如图1所示，其中包含了如下网元：
E-RAN(Evolved RAN，演进的无线接入网)：可以提供更高的上下行速率，更低的传输延迟和更加可靠的无线传输。E-RAN中包含的网元是eNodeB(Evolved NodeB)，为终端的接入提供无线资源。
MME(Mobility Management Entity，移动管理实体)：控制面功能实体，临时存储用户数据的服务器，负责管理和存储UE(User Equipment，用户设备)上下文(比如UE/用户标识，移动性管理状态，用户安全参数等)，为用户分配临时标识，当UE驻扎在该跟踪区域或者该网络是负责对该用户进行鉴权；处理MME和UE之间的所有非接入层消息；触发在SAE(Stand Alone Equipment，独立设备)的寻呼。
Serving GW(Serving Gateway，服务网关)：该网关是一个用户面实体，负责用户面数据路由处理，终结处于空闲状态的UE的下行数据。管理和存储UE的SAE承载上下文，比如IP承载业务参数和网络内部路由信息等，是3GPP系统内部用户面的锚点，一个用户在一个时刻只能有一个Serving GW；
IWS(Interworking Solution，互操作节点)：LTE覆盖下的终端不能处理语音业务时，可以先回退到电路域网络，在电路域网络处理语音业务。IWS负责实现LTE下的MME和电路域的MSC(Mobile Switch Center，移动交换中心) 的交互。
CDMA2000 1X接入网：主要包括MS移动终端和BTS(Base Transceiver Station，基站收发信机)。基站收发信机负责无线信号收发，实现无线网络系统和移动台之间的通信。
BSC(Base Station Control，基站控制器)：负责BTS控制和管理，资源分配，无线连接建立，移动性管理，功率控制等。
MSC(Mobile Switch Center，移动交换中心)：负责呼叫建立，路由选择，呼叫控制，无线资源分配，移动性管理，位置等级，交换区内信道切换等。
通过IWS网元完成MME与MSC网元的互通，IWS与MME之间采用S102接口UDP(User Datagram Protocol，用户数据包协议)隧道。
UE接入到LTE网络后，当需要向CDMA2000的MSC发送消息时，UE发送消息到MME，MME基于UE所在的小区ID选择IWS并转发消息，IWS为UE分配隧道资源，记录相关的信息，同时IWS向MSC转发消息。
由于UE移动到新的小区，UE所在的IWS会发生变化，选择了新的IWS，但原IWS中仍为此UE分配了资源，随着UE不断移动，原IWS将存在很多资源被分配，但UE已不属于原IWS的情况，造成资源浪费。
针对相关技术中上述的问题，目前尚未提出有效的解决方案。
