Research on migration program of users and equipment for the SGCC IMS administrative switch network

With switch technology evolving from the program-controlled to soft-switch, and IMS technology, the power switch network faces technology selection. Through an investigation and analysis into the administrative switch network of the State Grid, and study the migration and evolution technologies in depth, consider the characteristics of electric communication network, this paper presents an evolution program for users and switch equipment transfer from existing administrative switch network to the IMS network. It provides a reference for the evolution of the SGCC administrative switch network.
