| 摘 要： | IP多媒体子系统(IMS)采用SIP协议进行呼叫控制,与接入无关,支持各种综合业务,因此,ETSI和ITU-T已将其作为NGN的核心结构.首先简要介绍了IMS的网络架构及其特点,分析了基于IMS实现固定移动网络融合的优势,提出了基于IMS的网络融合方案,并指出这种融合方案所面临的问题与挑战.

| Abstract: | IP Multimedia Subsystem(IMS) use SIP as call session control protocol, and is irrelevant to access while providing various integrative services.Therefore ESTI and ITU-T have taken it as the core structure of NGN.This paper first presents the architecture and characteristic of IMS,then analyzes the advantages of implementing fixed-mobile convergence via IMS.The solution of network convergence via IMS is illuminated then;the problems about this solution are summarized at the end. |
