一种基于AS触发链的IMS多业务触发机制

IMS multi-service triggering mechanism based on the AS triggering chain

在分析现有全IP架构的核心网域(IMS)业务触发存在问题的基础上,结合基于业务键的多业务触发算法和基于分组的业务触发算法优点,设计了一个基于应用服务器(AS)触发链的多业务触发机制.利用Jackson排队网络理论对该机制的性能进行了分析,并进行了仿真实验.结果表明,该机制能够降低服务-呼叫会话控制功能与AS之间的通信量,提高了触发效率,具有良好的触发性能.

Based on the analysis of problems of current service triggering mechanisms,an IMS multi-service triggering mechanism based on the Application Server（AS） triggering chain,which has the advantages of the multi-service triggering algorithm based on the Service-Key and the Group based multi-service triggering algorithm,is proposed.The performance of this algorithm is analyzed by modeling the service triggering algorithm with the Jackson Queuing Network Theory,and experimental results show that the proposed algorithm can reduce the communication traffic between AS and S-CSCF and improve the triggering efficiency.
