摘　　要：分析了AS中业务逻辑触发机制的必要性,提出了SIP应用服务器中业务逻辑触发模型,详细定义了业务逻辑触发数据,并给出了SLTA。通过性能分析发现SLTA可有效地提高S-CSCF的吞吐量,降低系统时延,而提出的AS业务逻辑触发机制完善了现有IMS网络中的业务触发,对业务键和sFC的实现提供了一定的帮助,并从业务触发角度为IMS网络中的SIP应服务器设计提供了一条思路。The necessity of service logic triggering mechanism of AS was analyzed, and a service logic triggering model of SIP AS was proposed in this paper. The data of service logic triggering was defined in detail and the SLTA was presented, Performance analysis indicated that the SLTA can efficiently increase the throughput of the S-CSCF and reduce the delay of the ATA. The proposed service logic triggering mechanism perfects service triggering mechanism in existing IMS network, which is helpful to the implementation of Service Key and sFC. In addition, a way to design SIP AS in IMS network from the perspective of service triggering was provided.
