摘要
应用IMS技术开展基于IP的铁路调度通信系统方案研究,为铁路运输生产提供集语音、视频和数据于一体的多媒体调度业务。首先分析了既有铁路调度通信系统存在的问题及业务需求;然后通过对不同交换技术进行比较分析,给出技术体制选择建议;在此基础上,通过网络结构、节点设置及承载网络方案比选,提出了基于IMS的铁路调度通信系统的建议方案。
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.
