摘　　要：Web RTC将多媒体处理能力嵌入浏览器,无需用户安装插件或客户端即可进行网页实时音视频通信,是网络实时通信领域未来的发展趋势.SIP作为IMS的核心协议,已发展成熟并广泛应用.实现Web RTC与SIP互通是当下实时通信领域的发展方向.本文分析Web RTC和SIP互通需要解决的问题,并介绍当下Web RTC/SIP互通的两种解决方案:Java Script实现SIP协议方案和SIP/Web RTC转换网关方案.本文针对现存解决方案仅能实现两种控制协议转换的不可扩展性,提出一种可扩展的Web RTC控制协议转换网关结构.本文通过实现网关的Format、SIP和JSEP模块,验证所提出网关结构的可行性,并搭建Web RTC应用和SIP终端通信的实验环境进行测试,实验表明本文提出的可扩展的Web RTC控制协议转换网关结构是可行的.WebRTC enables web browers with Real-Time Communications capabilities natively, without the need for installing addi- tional third-party software or plugins. WebRTC is the future trend of the development of network real-time communication field. SIP is core protocol of IMS and it has been mature and widely used. Realizing the communication between WebRTC and SIP is the develop- ment direction of real-time communication. This paper analysis the problems should be sovled for the communication between SIP and WebRTC. This paper also introduces the existing SIP/WebRTC communication solutions and proposes a extendible architecture of WebRTC control protocol conversion gateway to support multiple signaling protocols. This paper implements gateway＇s function of conversion between SIP and JSEP. Experiments show that the proposed extendible architecture of WebRTC control protocol conversion gateway is feasible.
