IMS的初始过滤准则和业务提供技术研究

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。介绍了IMS的业务体系架构、初始过滤准则（iFC）和基于IMS的业务提供技术,并在实际的系统中进行了实现。实验结果表明,该触发机制保证用户发起IMS呼叫时能够正常使用IMS业务体系结构中所提供的业务。%IMS（IP Multimedia Subsystem）is the core technology of the next generation network and the perfect architecture of fixed-mobile convergence.This paper introduces IMS service system structure,Initial Filter Criteria and service provision technology based on IMS.A system is developed and an application scenario is showed.The analysis result indicates that the triggering mechanism ensures the normal use of services provided by IMS service architecture when a user is performing IMS calling.
