摘　　要：随着铁路移动通信由GSM-R向5G-R演进,基于GSM-R的CTCS-3级列控系统车地无线通信技术面临更新替代的问题。根据近年来5G-R承载CTCS-3级列控系统车地无线通信业务研究取得的成果,为充分利用5G-R的优势,将5G-R下CTCS-3级列控系统车地无线通信由单链路改为双链路冗余技术。以CTCS3-300H型列控车载设备为研究对象,分析车地无线通信冗余技术的适应性,研究车地无线通信的系统架构,以及不同网络制式下的移交方案等,提出适合于CTCS3-300H型列控车载设备的车地无线通信冗余技术实现方案。研究成果为CTCS-3级列控系统在5G-R下实现车地无线通信冗余技术提供思路和借鉴。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.
