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。 In MSC POOL networking, a BSC / RNC is served by multiple MSSs and the load sharing among nodes is used to reduce the impact of single MSS failure on the service and improve the network reliability. With the increasing degree of IP softswitch network, MSC POOL technology more obvious advantages, has been fully commercial. According to a mobile company MSC POOL networking project, first of all, how the existing network evolved into a POOL is studied, and corresponding solutions are put forward for many problems existing in the project, such as NRI resource shortage, load balancing and called problems .
