本文对某移动运营商交换网络现状及交换系统资源利用情况进行了分析,根据话务模型对用户数与业务量进行了预测,进而分析了网络性能需求。针对部分交换局域网负荷较高的问题,从向3G网络演进的角度考虑,在现有2G网络上采用移动软交换技术,通过引入软交换设备扩容的方式进行解决。 This paper analyzes the status quo of a mobile operator switching network and the utilization of switching system resources. Based on the traffic model, the number of users and traffic are predicted, and then the network performance requirements are analyzed. Aiming at the problem of high load on some switched LANs, from the perspective of evolution to 3G networks, mobile softswitch technology is used in existing 2G networks and the solution is introduced by introducing the expansion of softswitch equipment.
