Development and Evolution of Railway Mobile Communication

分析目前铁路移动通信的发展现状以及未来铁路发展GSM-R存在的主要瓶颈,针对铁路未来发展对铁路车地宽带通信的需求,探讨铁路移动通信的发展及演进方向,从业务及平台演进两方面提出了GSM-R向LTE-R演进的技术方案。研究表明,未来铁路GSM-R网络向LTE-R的方向演进是合理、可行的。

This paper analyzes the present status of developing the railway mobile communication and the main problems of developing GSM-R in the future. According to the demands of the train- ground broadband communication with the development of railways, it discusses the direction of the development and the evolution of the railway mobile communication, and puts forward the technical scheme of the evolution from GSM-R to LTE-R including two aspects of the service evolution and platform development. The research shows that the evolution from the GSM-R network to LTE-R is reasonable and feasible.
