| Abstract: | The scheme of railway dispatching communication system is studied based on IP by using IMS technology in order to provide multimedia dispatching services that integrate voice, video and data for railway transportation production. Firstly, the problems in the existing railway dispatching communication system and the business requirements are analyzed. Then, suggestions on the selection of technical system are given according to a comparative analysis of different switching technologies. On this basis, a scheme of railway dispatching communication system based on IMS is put forward through the comparison and selection of network structure, node setting and hosted network scheme. |
