摘　　要：随着我国5G网络建设日趋成熟,CTCS-3级列控系统及下一代列控系统承载大容量数据业务的需求也愈发强烈。5G-R网络作为替代GSM-R网络的下一代铁路通信移动系统,提供面向字节流的传输服务,具有宽带宽、高速率、低时延的优势,GSM-R网络下的无线通信协议已不再适用。从总体结构、协议分层和协议分割重组等方面对5G-R网络下的无线通信协议进行设计,从协议功能、传输可靠性、传输速率等方面对GSM-R网络和5G-R网络下的两种无线通信协议的差异性进行比对分析。5G-R网络下设计的无线通信协议可靠性更高、传输速率更快,可充分利用和发挥5G-R网络的优势。研究成果可对CTCS-3级列控系统在5G-R网络下的无线通信协议建设提供思路和借鉴。With the maturity of China's 5G network construction,the demand for carrying high-capacity data service for the CTCS-3 train control system and the next generation train control system is becoming stronger.As the next generation railway communication mobile system,the 5G-R network provides byte stream oriented transmission service,which has the advantages of wide broadband,high speed and low delay.Therefore,the radio communication protocol based on the GSM-R network is no longer applicable.In the paper,the radio communication protocol based on 5G-R network is designed from the aspects of overall structure,protocol layering,protocol segmentation/reorganization,and the differences between the two radio communication protocols based on GSM-R network and 5G-R network are compared and analyzed from the aspects of protocol function,transmission reliability and transmission rate.The radio communication protocol based on 5G-R network has higher reliability and faster transmission rate,which can make full use of the advantages of 5G-R network.The research can provide ideas and reference for the construction of the radio communication protocol base on 5G-R network for CCTS-3 train control system.
