文章提供一种在IP多媒体子系统(IMS)网络中实现交互式网络电视(IPTV)业务的方案。方案采用超文本传输呼叫会话控制功能设备(H—CSCF)提供Mw接口,接入IMS核心网,实现IPTV和IMS业务的融合组网。使得运营商无需对现有大量的IPTV终端进行升级和改造,就能在基于IMS的电信融合网络中提供IPTV业务;同时提供统一的用户管理、服务质量(QoS)保证、并支持与下一代网络其他业务的融合。对于已经布置了基于IMS通信网络的运营商,采用该方案可以简单地提供IPTV业务,也可以支持IPTV与其他通信业务的融合;同样对于已经布置了IPTV系统的运营商,采用该方案可以通过对核心设备的简单升级和改造,实现和IMS核心网的融合,降低运营成本。 相似文献

A solution is proposed to implement interactive Internet Protocol Television (IPTV) services in the Internet Protocol Multimedia Subsystem (IMS) network. The solution enables the IPTV system to access the IMS core network via the Mw interface provided by the HTTP Call Session Control Function (H-CSCF),fulfilling converged networking of IPTV and IMS services. It allows operators to offer IPTV services in IMS-based converged networks without upgrading and modifying the existing IPTV terminals. Moreover,it enables unified subscriber management and guaranteed Quality of Service (QoS),and supports the convergence with other NGN services. Based on this solution,IMS operators can offer IPTV services or IPTV-based converged services through an IMS architecture; IPTV operators can implement networking of IPTV and IMS by updating and modifying the core equipment,to reduce operational costs. 相似文献

HFC和IPTV释疑 总被引:1,自引:0,他引:1
近些年来,随着我国有线数字电视的推进和有线数据增值业务的开发.业界对HFC网络的业务适应性多有议论,似乎认为其对IP数据的接入不如以太网,尤其是IPTV的出现,似乎更感竞争压力骤增,甚至对其寿命都存有疑虑。于是,不少地方在已有HFC网的情况下.又新建了五类双绞线的以太网,居民家里又多了根双绞线; 相似文献
