摘要
为探讨重载铁路下一代通信应用场景下关键业务的技术方案,建立重载铁路5G-R标准体系架构,通过分析我国重载铁路通信系统的发展与演变过程、研究国际UIC FRMCS标准体系以及3GPP架构、调研国内5G-R场景下重载铁路业务需求,提出符合我国重载铁路实际的5G-R架构模型。根据需求类型划分关键业务和使用对象,根据应用场景的业务特点以及通信内容确定各个关键业务的线路优先级、可靠性和实时性,最后针对机车同步操控业务、可控列尾安全防护业务、多司机通话业务等重载铁路关键业务设计可行技术方案。研究结果可降低重载铁路下一代通信关键业务的系统设计复杂度,对提升重载铁路运输生产安全和效率具有指导意义,从而为重载铁路5G-R标准体系架构和关键业务方案设计提供参考。
In order to explore the technical solutions for key services under the next-generation communication application scenarios of heavy-haul railways and establish the 5G-R standard system architecture for heavy-haul railways,this paper analyzed the development and evolution process of heavy-haul railway communication systems in China,studied the international UIC FRMCS standard system and the 3GPP architecture,and investigated the business requirements of heavy-haul railways under the 5G-R scenarios in China.This paper proposed a 5G-R architecture model that met the actual situation of heavy-haul railways in China,divided key services and usage objects according to the demand type,and determined line priority,reliability,and real-time performance of each key service according to the service characteristics of application scenarios and communication content.It also designed feasible technical solutions for the key services of heavy-haul railways,such as operation and control service for locomotive synchronization,controllable end-of-freight train safety service,and multi-driver communication service.The results can reduce the system design complexity of the next-generation communication key services of heavy-haul railways,which is of guiding significance to enhance the safety and efficiency of heavy-haul railway transport and production,thus providing a reference for the design of the 5G-R standard system architecture and key service solutions for heavy-haul railways.
