Development of Urban Rail Transit Special Communication Network based on Soft-switching Technology |
| |
| Abstract: | The development status and problems of rail transport special communication network are described.In combination of current large scale construction of rail transit and the requirements of intelligent management and networked operations,the advantages of the development of soft-switch technology in urban rail transit are analyzed and it is pointed out that the IP network based on soft-switching technology will be the development direction of special communication network for urban rail transit in the future.Furthermore,the network planning of soft-switching communication network for urban rail transit is expounded together with network evolution strategy and transformation of old network. |
