软交换作为话音网向数据网融合的下一代网络(NGN)的主要技术,以清晰的业务分层模式、高效的分组交换机制正日益受到电信运营商的重视。以中国电信为例,去年分别在深圳、广州、上海、杭州及北京,对中兴、北电、爱立信、阿尔卡特、西门子5家厂商的软交换设备进行了测试和评估鉴定工作。业界对NGN的总体评价褒贬不一,对NGN技术急需要解决的问题也仁者见仁,智者见智。本文试图从宏观上就NGN软交换的几个问题做分析探讨。

Softswitch, as the main technology of next generation network (NGN) converged from voice network to data network, is gaining more and more attention by telecom operators due to its clear business layering model and efficient packet switching mechanism. Take China Telecom as an example. Last year, it conducted testing and appraisal of the softswitch equipment of five manufacturers including ZTE, Nortel, Ericsson, Alcatel and Siemens in Shenzhen, Guangzhou, Shanghai, Hangzhou and Beijing respectively. The industry’s overall evaluation of NGN mixed, on the urgent need to address the issue of NGN technology benevolence, wisdom wise. This article attempts to analyze and discuss several issues of NGN softswitch macroscopically.
