摘要

公共交换电话网/综合业务数字网（PSTN/ISDN）仿真子系统作为下一代网络（NGN）多个业务控制子系统之一

其实现架构主要有两种方式:基于呼叫服务器的方式和基于IP多媒体子系统（IMS）的方式。两种方式各有优劣。文章对这两种方式作了简要介绍

并从核心架构、业务实现方式和演进方式等方面进行了比较分析

最后结合国内电信网络的发展和现状对方案的选择提出了建议。

Abstract

PSTN/ISDN emulation subsystem is one of the NGN service control subsystems.There are two PES architectures

call server-based emulation and IMS-based emulation.Each of them has its own advantages and disadvantages.In this paper

the two architectures are briefly introduced and the comparison and analysis of them made in respect of core architecture

service providing method and evolution scenarios.Finally

suggestions for the scheme selection are given on the basis of the status quo and development of telecom networks in China.
