摘　　要：近年来,基于IMS技术的行政交换网络在电力系统得到全面推广应用,其在提供业务个性化、服务差异化的多媒体通信业务服务的同时,也在一定程度上加大了整个交换系统的不可靠性与性能风险。论文在深入研究SIP信令流程的基础上,提出了一种基于Petri网的IMS行政交换网信令性能分析方法,从而为增加整个系统的吞吐量,减少会话建立时延,为提高IMS网络服务质量给出了改进思路。In recent years,the administrative switching network based on IMS technology has been widely used in power system. While providing individualized and differentiated multimedia communication services,it also increases the reliability and performance risk of the whole switching system to a certain extent. Based on the in-depth study of SIP signaling process,this paper proposes a signaling performance analysis method for IMS administrative switching network based on Petri net,which can increase the throughput of the whole system,reduce session setup delay,and improve the service quality of IMS network.
