分布式IMS媒体会话控制技术研究

Research on Media Session Control Technology based on Distributed IP Multimedia Subsystem

IMS和P2P技术目前都是最热门的技术,但本身各自既有优势又存在不同缺陷,如果能够将IMS强大的业务控制能力和P2P强大的业务承载能力进行结合,可以达到完善和改进目前通用IMS网络的目的。主要提出了一种基于IMS网络和P2P技术结合下的分布式IMS媒体会话控制方式,具体针对媒体会话控制实体的分布式设计、业务控制实体的即插即用实现方式、以及业务控制实体的负载均衡实现方式等方面都提出了一些解决思路。

Both IMS and P2P,as popular technologies,have their own merits and limitations in certain aspects,and an integration of these two technologies could improve and perfect the common IMS network.This paper proposes a media session control mode based on distributed IP multimedia subsystem and P2P technology,and then provides some solution ideals on the distributed design of session control entity,the plug-and-play mode of business control entity,and the load balance implementation pattern of business control entity.
