The CTCS-3 train control system is a critical system that ensures the safe operation of trains at 350 km/h.It represents a crucial core service carried by the railway wireless communication system,and it demands exceptionally high reliability for train-to-ground data communication.The high reliability,low latency,and enhanced high-speed adaptability of 5G-R technology are in line with the business requirements of CTCS-3 train control system.This paper analyzes the necessity of integrating 5G-R technology into the CTCS-3 system and explores the challenges associated with CSCS-3 data transmission in 5G-R network.Additionally,this paper discusses the technical roadmap and implementation strategies for upgrading and adapting Chinas future train control system to be compatible with the 5G-R network.The mechanism of CTCS-3 train-to-ground data transmission in 5G-R network and the application of 5G-R/GSM-R dual-mode wireless radio module in 5G-R-based CTCS-3 train control system are introduced.By conducting function and performance experiments of CTCS-3 train control data transmission in the 5G-R network laboratory environment and comparing the performance indicators with CTCS-3 data transmission in GSM-R network,the paper evaluates the applicability of CTCS-3 data transmission in 5G-R network.Furthermore,the paper investigates the principles of the quality of service assurance mechanism in 5G-R network,dedicated QoS characteristics of train control services,and the establishment process of dedicated QoS flows in the CTCS-3 train control system.Through experiments,it is demonstrated that the QoS assurance mechanism of the 5G-R system can prioritize the stable and reliable transmission of CTCS-3 train control data services,even in situations with scarce network resources.
