随着网络技术的高速发展,传统的PSTN网络系统已经不能满足人们的需求,随着即时通信等新技术的应用,新一代的NGN网络逐渐发展起来,NGN网络是统一整合了信令网关、智能终端、媒体网关以及媒体服务器等内容,虽然近年来得到了很快的发展,但是仍然存在着一些问题,其中比较突出的一点就是基于软交换平台的用户接入问题。本文结合笔者多年工作经验,对基于SIP协议的软交换平台和网关设计方案进行了初步探讨,以期为同行提供一定的参考。
With the rapid development of network technology, the traditional PSTN network system can no longer meet the needs of the people. With the application of new technologies such as instant messaging, a new generation of NGN networks is gradually developed. The NGN network is a unified integrated signaling gateway, The contents of terminals, media gateways and media servers, etc., have been rapidly developed in recent years. However, some problems still exist. One of the more prominent ones is the user access problem based on the softswitch platform. Based on the author’s many years of work experience, this article has carried on the preliminary discussion to the design scheme of softswitch platform and gateway based on SIP protocol, with a view to provide some reference for peers.
