基于IMS的IPTV架构及其对IMS网络架构的影响分析

IMS-Based IPTV Architecture Analysis and the Influence of IMS-Based IPTV on IMS Network

在电信网、广播电视网、互联网三网融合的趋势下,基于IMS网络提供IPTV业务是IPTV近年来的主要发展方向之一。各国际标准化组织已经进行了较为深入的研究工作。本文首先介绍各标准化组织的相关研究进展,而后针对IPTV业务的特点,在国际标准化组织研究基础上提出基于IMS的IPTV体系架构并进行分析,最后着重分析IPTV业务对IMS网络的影响。

With the tendency of convergence of telecommunications network, broadcast and TV network and Inter＇net, IMS （IP multimedia subsystem）-based IPTV represents the evolutionary direction of IPTV development in the near future. International standardization bodies have been working on IMS to enable provision of IPTV services （IMS-IPTV）. This paper firstly presents the current standardization efforts of IMS-IPTV in ETSI TISPAN and ITU-T. Secondly, it presents the IMS-IPTV layered architecture anti analysis based on the IMS-IPTV service characters. Finally, it provides analysis of the influence of IPTV services on IMS network.
