Abstract
The article is devoted to the features of GSM-R as a basis for organizing a digital radio communication system on the railway to apply the European Integrated Radio Communication for the railways of Uzbekistan. The role of GSM-R for the interaction of digital radio communication with the European integrated system for expanding the functions of railway radio communication and safe movement of high-speed trains is shown. The article identifies the possibilities of building modern digital communication of the railway. The GSM-R communication network, its services and architecture for organizing digital communication were also defined. Recommendations on the use of GSM-R on the railway of Uzbekistan are given. It has been established that mobile communications should be a heterogeneous (heterogeneous) architecture. Also, it must have a variety of access networks that could operate in any frequency ranges.
Highlights
The digital railway area needs modern functional and operational applications that are required for safe train traffic control systems and other information systems compared to the general telecommunication sector
For the transition to the European system of railway transport management, it is necessary to use the standard for the movement of trains in the driver's cabin (ETCK) and mobile communication for the management of freight and passenger traffic (GSM-R) [2, 3]
Packet switching LTE and R can become a receiver of the global system of digital railway communications (GSM-R) network, which will be equipped with 5G equipment
Summary
The digital railway area needs modern functional and operational applications that are required for safe train traffic control systems and other information systems compared to the general telecommunication sector. The digital system includes a whole range of information technologies: control of the movement of freight and passenger trains, station complexes, signals and switches, traction rolling stock. For the transition to the European system of railway transport management, it is necessary to use the standard for the movement of trains in the driver's cabin (ETCK) and mobile communication for the management of freight and passenger traffic (GSM-R) [2, 3]. Integrated Railroad Mobile (GSM-R) provides a diversified set of services, interoperability, broadband 4MHz bandwidth, and 876-880MHz range. Interference occurs when using broadband 3G and 4G / LTE mobile networks In this regard, it is necessary to develop a new mobile communication system FRMCS (Future Railway Mobile Communication System), in which packet switching of the two LTE and R systems would replace LTE-R and 5G-R. Implementing the new version of LTE Rellase 12 will help create a variety of standardized interfaces on digital railways [20, 21, 22]
