Technical Solution for Railway 5G-R-Based Train-Trackside Wireless Communication Redundancy of CTCS3-300H Train Control Onboard Equipment
With the evolution of railway mobile communication from GSM-R to 5G-R,the GSM-R-based train-trackside wireless communication technology in the CTCS-3 train control system faces the challenge of modernization and replacement.Based on the achievements of recent research on train-trackside wireless communication of the CTCS-3 train control system supported by 5G-R,this study proposed changing the train-trackside wireless single-link communication of the CTCS-3 train control system to dual-link redundancy in the 5G-R environment to fully leverage the benefits of 5G-R.Focusing on the CTCS3-300H train control onboard equipment,this study analyzed the adaptability of train-trackside wireless communication redundancy technology,examined the system architecture of train-trackside wireless communication,and explored handover schemes for different network types.Furthermore,an implementation scheme was proposed for train-trackside wireless communication redundancy technology applicable to CTCS3-300H train control onboard equipment.The findings offer insights and references for implementing train-trackside wireless communication redundancy technology in the CTCS-3 train control system in the 5G-R environment.
