MSC POOL组网工程中若干问题研究

Study of Problems in MSC POOL Networking Engineering

MSC POOL组网中,一个BSC/RNC由多个MSS为其提供服务,节点间采用负荷分担的方式,降低了单个MSS故障对业务的影响,提高了网络可靠性。随着移动软交换网络IP化程度越来越高,MSC POOL的技术优势更加明显,已得到全面商用。根据某移动公司MSC POOL组网工程,首先研究了现网如何演进成POOL的方法,并针对工程中存在的诸多问题,如NRI资源缺少问题、负荷均衡问题、被叫问题提出了相应的解决方案。

A BSC/RNC is served by several MSSs in MSC POOL, and by load sharing between MSSs, the impact of single fault is reduced and the network credibility improved. With the increasing degree of IP in mobile soft switch network, MSC POOL, owing to its technical advantages, acquires an entensive commercial application. Based on MSC POOL networking engineering, how the exiting network evolves into MSC POOL is studied first, and then for the problems in the engineering such as the shortage of NRI resource, load balance and that the called party cannot connected, some proper solutions are also proposed.
