摘　　要：总结专用于城市轨道交通车地通信的WLAN(wireless local area network,无线局域网)和LTE-M(long term evolutionformetro,城市轨道交通长期演进)主要承载的业务,给出LTE-M综合承载列车运行控制、视频监控、集群调度等多业务网络结构。针对城市轨道交通业务需求和发展,探讨专网5G技术的构建及设计网络方案,论述5G专网应用对城轨发展的促进作用,并分析该过程存在的主要问题,提出相关的解决方法和手段。In this study, I examine the main services provided by wireless local area networks and long term evolution for machines(LTE-M) dedicated to urban rail systems. I propose that the LTE-M system integrates the network structures of train operation and control, image monitoring, and trunk dispatching services. The deployment of 5 G in train-to-ground wireless communications systems is discussed based on the needs of services in urban rail and the network plan is designed. In addition, we analyze the benefits to urban rail of the application of 5 G. Finally, the main problems in the process and relevant solutions are proposed.
