一种可支持多种多媒体业务的基于IMS的IPTV架构

摘要

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.%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IMS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.
