基于LTE的有轨电车车地通信全业务承载方案研究

Research on Train-ground Communication Full Service Carrying Scheme of Tram Based on LTE

国内轨道交通项目中LTE综合承载信号列控、语音集群、视频及数据中的部分业务案例较多,全业务承载国内尚无开通案例。通过对LTE技术及原理的分析研究,结合抗干扰、基站布置及时隙配比等方面的规划,为有轨电车全业务承载提供合理可行的方案,并提出优化建议。

There are many cases of LTE integrated traffi c signal control,voice clustering,video and data in China's rail transit projects,but there is not open case of full service carrying.Through the analysis and research of LTE technology and principles,combined with the planning of anti-interference,base station layout and slot ratio,this paper provides a reasonable and feasible plan for tram full service carrying,and puts forward some suggestions for optimization.
