IMS技术及其在天津电力交换网中的应用

IMS Technology and Its Application in Tianjin Electric Power Exchange Network

摘要: IMS技术是引领全IP网络的关键技术之一，它是以用户为核心的理念发展的必然结果。目前电力行政交换网提供以语言交换为主的业务，不能适应电力系统业务IP化的发展趋势，所以在电信业务交换网络逐步引入IMS体系架构的同时，电力专网也开始涉足这一新技术。文章对IMS技术体系架构、功能实体和特点进行了介绍；对IMS技术和软交换技术进行了比较，得出IMS技术的优点；简要介绍了电力系统交换网及天津交换网现状；最后提出了IMS技术在天津电力交换网中的应用方案。

Abstract: Based on the idea of customer-oriented, IMS (IP Multimedia Subsystem) is one of the key technol-ogies of all-IP network in future. For the existing administrative switching network, the voice switch is the main service. But it can’t adapt the development trend of the power system IP business, so the telecommunication business network is introducing the IMS technology while the electric power business network begins to try this new technology. This paper introduces the architecture, the function entity and the characteristics of IMS. It also contrasts with soft-switch to show the advantages of IMS technology. It basically introduces the present situation of Tianjin electric power exchange network. Finally, it proposes an application scheme of IMS in Tianjin electric power exchange network.
