摘要
SIP和H.323是构造远程教育网络的两大信令体系,实现SIP和H.323协议互通是保证远程教育网络顺利运营的一个关键问题。如何有效地实现这两种协议之间的互通,成为近年来国内外的研究热点。通过比较H.323与SIP的网络结构,分析互通过程中需要处理的主要问题,提出了一种实现H.323与SIP互通的远程教育系统模型,并对地址、消息映射及媒体能力的问题提出了相应的解决方法。
SIP and H. 323 are two kinds of signaling systems that form distant education network, the realization of interworking between SIP and H. 323 protocols is a key question to make distant education network operate smoothly. How to achieve the interworking protocol has been a hot issue at home and abroad these days. Through a comparison of network architecture between SIP and H. 323, by analyzing the main problems existing in interworking procedure, a model to realize interworking between SIP and H. 323 is given, and some corresponding solutions related to address, message mapping and medium＇ s capability are put forward.
