摘要
IP多媒体子系统(IMS)是下一代网络的核心技术,是被业界认可的实现移动和固定网络融合的理想方案。IMS引入了归属位置寄存器(HSS)功能实体,它是IMS系统的数据中心,是支持用户移动性和呼叫控制的关键,也是IMS服务扩展的核心。现介绍IMS网络中HSS的功能结构,阐述如何通过HSS的IFC规则来实现IMS业务的扩展。通过IPTV业务的实现,说明IMS网络业务有着良好的可扩展性,这也对IMS系统的深入研究提供了必要的技术积累。
IP multimedia subsystem is the core technology of next generation network, and is considered as ideal plan in migration and fixed network fusion field. IMS has HSS function entity. It is the data center of IMS system, the key of supporting user mobility and the call controls, and also is the core of the IMS service expands. The paper mainly introduces the HSS function in IMS network, and shows how to realize the IMS service expansion through the HSS IFC rule. Through the realization of IPTV service, it explains the IMS has good extendibility, and it also provides the necessary technical accumulation for further researching of IMS.
