基于Service Broker的IMS业务特征冲突解决算法与方案

Algorithm and Solution of IMS Feature Interaction Based on Service Broker

3GPP在UMTS R5中提出IMS作为下一代网络(NGN)技术在移动通信中的实现,但IMS业务触发机制的缺陷给交互管理带来挑战。把IMS中业务特征冲突分为SCFI(Single Component Fea-ture Interaction)和MCFI(Multi-component Feature Interaction)两类,利用SIP协议的可扩展性携带业务触发信息,提出解决MCFI类业务冲突的算法及方案。此方案为3GPP Service Broker标准制定提供了参考。

IMS introduced by 3GPP in UMTS R5 is the realization of next generation network（NGN） in mobile network, and the defect of IMS service invocation mechanism brings challenge to the feature interac- tion. This paper classfies the feature interaction to two types, or single component feature interaction （SCFI） and multi - comporient feature interaction （ MCFI）, presents a solution of the MCFI in IMS architecture, and gives two examples to illustrate the application of this solution. The solution provides reference for 3GPP Service Broker standard.
