MSC Pool技术在河南移动网络中的研究和应用

MSC Pool technology research and application in Henan Mobile network

本文针对MSC Pool技术在河南移动实际组网中和容灾场景中遇到的自动容灾和被叫恢复问题,进行了深入的分析并提出了有效的解决方案,将3GPP协议中的VLR Restore流程引入到MSC Pool容灾场景,利用SCCP层备份寻址实现HLR路由数据的自动倒换。多次模拟实验证明,该方案能够自动,零时间内实现核心网网元级设备容灾场景下的一次被叫恢复难题。并且,本方案属于零投资、采用开放的协议和规范、不局限设备厂家和软件版本,为MSC Pool技术在河南移动的大规模应用铺平了道路,确保了区域经济的平稳、健康发展。

Based on the in-depth analysis of problems upon disaster tolerance and called-number recovery in actual network deployment of Henan Mobile, the paper put forward an effective solution, which introduces the VLR Restore process within 3GPP into the MSC Pool disaster recovery scenarios, and realizes the automatic switching of HLR routing data by using SCCP backup addressing. Through large numbers of simulated experiments, this program solved the problem of called-number recovery in core network disaster tolerance scenarios, can restore the call automatically immediately. Moreover, the program utilizes the open protocols with zero investment and is compatible with different equipment manufacturers and software versions.
