软交换系统的应用与分析

Application and Analysis of Softswitch System

在通信技术日新月异的时代,软交换系统因其稳定性强、灵活性高以及扩展性好等特点被广泛应用。在自动电话网领域,需要依托软交换系统完成程控交换系统向IP多媒体系统(IP Multimedia Subsystem,IMS)的平滑过渡。从软交换的发展、结构、特点等方面进行介绍,与程控交换进行对比,基于具体设备进行组网方案设计。

In the era of communication technology changing with each passing day,softswitch system is widely used because of its strong stability,high flexibility and good expansibility.In the field of automatic telephone network,it is necessary to rely on softswitch system to complete the smooth transition from program-controlled switching system to IP Multimedia Subsystem(IMS).This paper introduces the development,structure and characteristics of softswitch,compares it with program-controlled switching,and designs the networking scheme based on specific equipment.
