摘要
目前的MCU视频会议主要基于H323标准,适合在专用网内进行部署。设计一种基于SIP的MCU视频会议系统,该系统在软交换网关和MCU分别进行H323和SIP信令互换;呼叫处理部分用标准的SIP信令来实现,业务逻辑用以SIP应用服务器控制,应用服务器与Web服务器间用TCP/IP通信,将会议的媒体处理单元(MCU)、终端、资源管理器、Web服务器有机的结合在一起。
Current MCU video conference is mainly based on H323 protocol which is suitable to be deployed on specific network. We designed a SIP （session initiation protocol） based MCU video conference system. Its gateway exchanges signals between H323 and SIP mutually at MCU and soft-switch gateway respectively. It uses standard SIP signals to accomplish calling process, the service logic is controlled by SIP application server, and the server uses TCP/IP to communicate with Web server. All these combine media process unit （MCU） , terminals, resource manager and Web Server together well.
