基于软交换IP中继媒体网关的实现

随着IP技术的发展,传统的PSTN通信网络也在逐步向IP网络方向发展,下一代网络(NGN)是融合话音、数据和图像的多业务IP网络,是未来通信网络的发展方向。基于当前通信网络的实际情况,简单介绍了基于软交换的中继网关的特点和功能结构。

With the development of IP technologies, traditional PSTN communication network also evolves into IP networks gradually. NGN, a type of IP network, which merge voice, data and video services, has become the trend of evolution. Based on the situation of today＇s communication network, this paper introduced the characteristics, functions and structure of softswitchingbased medium relay gateway.
