摘　　要：随着通信技术的逐步发展,电力企业原有的以程控交换技术为主导的语音业务已经无法满足现有需求,现有电力行政交换网需逐步向IMS演进。本文根据地市公司行政程控交换网的现实情况,探索程控交换向IMS演进的方法,为行政交换网逐步向IMS演进提供相关网络架构。With the development of communication technology,the existing voice service based on SPC switching technology has been unable to meet the needs of people,and the existing exchange network should evolve to IMS gradually.Combined with the actual situation of SPC exchange network,this paper discusses the evolution of existing SPC switching to IMS,and provides the relevant network architecture for the evolution of IMS to SGCC City Branch Company.
