摘　　要：从GSM-R时代开始,铁路无线通信专网的可靠性一直是用户最关心的。GSM-R在网络级使用交织组网或共站址双网的方式组网,达到网络级可靠性的目标;在设备层面使用冗余技术进行硬件备份。随着铁路无线通信技术即将步入5G时代,网络级和设备级的可靠性方案再一次成为一个重要研究课题。回顾铁路5G专用移动通信可靠性需求和实现方案,分析铁路5G专用移动通信可用的冗余技术,最后提出应用于不同线路的可靠性方案。Since GSM-R era,the reliability of private network for railway radio communication has always been of utmost concern for users.GSM-R uses interwoven networking or co-site dual-network networking at the network level to achieve the goal of network-level reliability;redundancy technology is used for hardware backup at the equipment level.As the radio communication technology of railway is about to enter 5G era,the network-level and equipment-level reliability scheme has once again become an important research subject.This paper reviews the reliability requirements and implementation schemes of railway 5G private mobile communication,analyzes the redundancy technologies available for railway 5G private mobile communication,and finally puts forward the reliability scheme applied on different tracks.
