双归属技术在重庆联通软交换组网中的应用

Application of dual homing in mobile core network of China Uicom Chongqing Branch

双归属组网方式能较好地实现对软交换server的保护。重点介绍重庆联通双归属组网中主备server的倒换倒回机制、数据同步机制、虚拟server及各种接口配置机制;分析重庆联通双归属倒换演练中存在的"某个MGW(media gate way)下的用户无法注册到备用MSC-server(mobile switching center-server)、智能网用户不能立即被叫"等问题,并提出相应的解决办法,这些经验对其他运营商有一定的参考价值和意义。

Dual homing network mode can achieve better protection of the soft switching server. Focuses are on Chongqing Unicom main server dual homing network switching back mechanism, data synchronization mechanism, virtual server and various interface configuration mechanism. In swap rehearsal of Chongqing Unicom, there are two questions which need to solve： one is ‘a MWG user can not be registered to the standby MSC-server’, the other is ‘intelligent network users can not be immediately called’. Then we put forward the corresponding solutions. It has some reference value and significance to other telecommunication operators.
