摘要
介绍了SIP协议的概貌,重点讨论了SIP功能实体和SIP消息,并对SDP协议的核心进行解释,研究了SIP协议及其将来的PINT协议在智能网与Internet互通环境下的应用,同时独创性地将In-ternet侧的实体与传统PSTN网侧的实体进行对比,将PINT实体与SIP实体进行对比,达到了智能网对PSTN和Internet统一控制的目的。
An overview of Session initiation Protocol is given in this paper. Then this paper focuses on functional entities and messages of SIP. Also the kernel of Session Description Protocol is described. More importantly, the application of SIP protocol and PINT protocol in the context of IN and Internet interworking is studied. Then entities in IP network are com- pared with entities in traditional PSTN, and PINT entities are compared with SIP entities, resulting in a uniform approach for IN to control PSTN and IP net- works.
