摘要
分析了SIP的特点,提出了一种NGN网络下的视频会议系统模型,采用了会议控制、媒体混合和用户交互三种功能模块分离,各子系统分层设计的设计方案,并基于此系统模型对部分关键功能模块进行了设计实现,为SIP多媒体会议应用的进一步研究、开发和推广提出了很好的建议.
Through an in-depth analysis of SIP, this paper presents a model of NGN video conference system, which adopts a separats model of conference control function, media mixing function and users' mutual function and a program of each subsystem design stratified. This study realizes the design of some key function unit on the basis of NGN model, which works out a good suggestion for the further research, development and popularization of SIP multi-media conference system.
