摘要
IP多媒体核心子系统(IMS)近年来日益成为比较受认同的固定网络和移动网络融合的理想方案,而会话发起协议(SIP)是IMS的基本控制协议,它自身的特点使得它在固网和移动网络向下一代网络(NGN)迈进的过程中发挥日益突出的重要作用。文章就SIP在IMS中的基本应用、扩展应用做了具体的分析,并通过IMS中SIP信令典型流程阐述了SIP在IMS中的应用。
In recent years IMS has gradually become the ideal scheme for the convergence of fixed network and mobile network which has been approved broadly. SIP is the fundamental control protocol of IMS and is playing increasingly an important role in the process of the transition from fixed network and mobile network toward NGN because of the characteristics of SIP itself. This article analyses the applications and expanded applications of SIP in IMS by using the typical process of SIP signalling flow in IMS.
