摘　　要：研究目的:为加快构建新发展格局,促进经济要素顺畅流动,建设以轨道交通为骨干的现代化综合交通网络成为服务国家重大战略的重要支撑,推动城际铁路等轨道交通融合发展的需求日益迫切。当前,大量计划和在建的城际铁路存在与干线铁路、城市轨道交通的互联互通需求,但尚无关于无线通信业务的统一标准,GSM-R、LTE、5G、Wi-Fi、毫米波等多种移动通信技术制式并存。为满足城际铁路通信业务需求,促进互联互通进程,对城际铁路无线通信业务种类、承载方式和服务质量指标的研究迫在眉睫。研究结论:(1)提出了15种城际铁路无线通信业务的应用场景、通信模式、业务特点和服务质量指标;(2)结合5G等当前主流通信制式,提出了适用于城际铁路的通信系统及其适合承载的通信业务种类;(3)验证了城际铁路无线通信业务服务质量指标的可行性;(4)本研究成果对城际铁路与干线铁路、城市轨道交通在移动通信方面技术规范衔接融合,提升运输生产安全与效率,提升运输服务品质具有参考意义。Research purposes: In order to accelerate the new development pattern and boost economic development, the construction of modern comprehensive transportation railway network with rail transit as the backbone has become an important support to serve the major national strategy, and the developing interoperability requirement of intercity railway is increasingly urgent. Although intercity railway has interconnection requirements with national railway and urban railway system, there is no specific standard for wireless communication service. A variety of mobile communication technology standards coexist in intercity railway, such as GSM-R, LTE, 5 G, Wi-Fi and millimeter-wave. In order to achieve requirement of intercity railway and promote the process of interoperability, it is urgent to study on the types, carrying mode and QoS index of intercity railway wireless communication service.Research conclusions:(1) The application scenarios, communication mode, application characteristics and service quality index of 15 kinds of intercity railway wireless communication service are proposed.(2) Combined with the current mainstream communication technology such as 5 G, the communication system suitable for intercity railway and its communication services are proposed.(3) The feasibility of raised QoS index of intercity railway wireless communication service is verified.(4) The research results have important reference significance for the interoperability of inter-city railway, national railway and urban rail transit in mobile communication technical specifications, and the improvement of transportation production safety efficiency, as well as the improvement of transportation service quality.
