摘要
会议初始化协议(SIP)是一种基于应用层地信令控制协议,由于具有简单、灵活和良好扩展性地体系结构,将其融入Internet数字语音通信技术中,建立基于SIP的VoIP网络,将会成为下一代VoIP技术的发展趋势之一。为此,介绍了一种基于SIP协议的VoIP网络实现模型,详尽阐述了SIP在VoIP网络中的实现原理,以及SIP对整个对话的控制过程。
Session Initial Protocol （SIP） is a signaling control protocol, which based on the application layer. Because of the simple, agile and expansible system architecture, it can be syncretized to digital voice communication; to build a SIP based VoIP network will be one of the most important components for the new VoIP technique. In the paper a VoIP network model based on SIP is introduced, the work principle of SIP in this model is discussed, and the process of SIP controlling whole session is described.
