摘要
铁路专用移动通信系统(Global System for Mobile Communications-Railway,GSM-R)正在向基于5G的铁路移动通信系统(5G-R)演进,基于普速与高速线路业务需求特性,对5G-R不同等级线路的无线组网方案进行研究,分析在单、双基带处理单元(Baseband Unit,BBU)不同组网方案下,设备故障的处理方式及影响范围,为5G-R无线组网工程的应用和规划提供参考与借鉴。
There is an ongoing evolution of Global System for Mobile Communications-Railway(GSM-R)towards the 5G based railway mobile communication system(5G-R).On the basis of the service requirement characteristics of conventional and high-speed lines,this paper studies 5G-R wireless networking solutions for different types of railway lines.It analyzes the handling methods and impact range of equipment failures under different networking solutions based on single BBU and double BBUs,providing reference and guidance for the application and planning of 5G-R wireless networking solutions for engineering projects.
