为了使IMS网络提供更加灵活的移动性支持,提出了一种无差别移动性管理网络。这种网络可以提供良好的服务移动性和用户移动性,使得用户可以永远以本地用户的身份使用接入地的服务,并对在此网络结构下的用户位置管理和会话建立进行了分析。实验结果表明,这种网络结构可以很好地支持用户移动性和服务的移动性。并且在此网络结构下的会话建立开销和用户位置注册开销,均比IMS目前采用的归属地控制方式下的用户注册开销和会话建立开销要小。
The differenceless mobility management network was proposed to support the mobility of IMS better. This kind of network can provide excel service mobility and user mobility, and it make user use service as local user in where it access the network. The user location management and session creation were analyzed. The result proved its target. It also proved that under this network architecture the cost of user location register and session creation is lower that home control model which IMS nowadays employs.
