Abstract 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, 5G, 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 5G, 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.

Key words： intercity railway wireless communication service 5G LTE-M millimeter wave communication train control and dispatching
