| 摘 要： | 在近年来随着用户对音视频通话质量要求的提高，WebRTC以其强大的多媒体处理能力得到了广泛的应用.然而WebRTC提供的JSEP是一种弱信令，在企业级的融合通信应用中必须将WebRTC与实际的信令协议相结合.SIP是IMS的核心技术，对多媒体会话的控制起着非常重要的作用.本文介绍了WebRTC和SIP协议融合的已有方案，研究了WebRTC和SIP协议互通需要解决的问题，提出了一种WebRTC的PeerConnection层和SIP协议在客户端的融合方案，并和其他方案对比，得出该方案的优缺点.

| Abstract: | In recent years, with the user''s requirements on the audio and video communications quality being higher, WebRTC has been widely used for its powerful multimedia processing capabilities. WebRTC only provide a kind of weak signaling JSEP, but enterprise-class converged communications applications must be combination of WebRTC and the actual signaling protocol. SIP protocol is the core technology of IMS, which plays a very important role in the control of multimedia conversation. This paper introduces the existing schemes of WebRTC and SIP protocol integration, studies the problems of WebRTC and SIP protocol integration, and presents a scheme of converged communications of combining WebRTC PeerConnection and SIP protocol based on clients. This study also compares the advantages and the disadvantages of this scheme with other schemes. |
