一种可支持多种多媒体业务的基于IMS的IPTV架构

IMS-based IPTV Framework with Various Multimedia Services to Support

IP多媒体子系统用于实现端到端的IP多媒体通信,具有接入无关性、对各种接入技术广适性的特点,因此,下一代网络采用IP多媒体子系统作为核心架构.提出一个基于IP多媒体子系统的IP电视架构,在IP多媒体子系统核心模块的基础上,以一组互相独立的基于会话初始化协议的功能模块构成应用服务器,并设计了能够支持和提供不同IM S业务的客户端与内容提供商端,使该IPTV框架可以在下一代网络上支持基于IP多媒体子系统的包括IPTV业务在内的多种多媒体业务.

IP multimedia subsystem（IMS） realizes the end-to-end IP multimedia communications and is independent of access technologies and has far-ranging adaptability to all kinds of access.IMS is confirmed to be the core architecture of NGN.This paper proposes an IMS-based IPTV architecture that enables various multimedia services including IPTV service based on IMS over NGN.The architecture is based on IMS core modules,and the application server is composed of stand-alone SIP modules.User end and content provider end are designed for supporting and providing various IMS services.
