Recently, in order to further improve the "distribution service" reform work, implement the requirements of the regulations and documents of the clean-up department of the General Office of the State Council, according to the actual situation of railway reform and development, in accordance with the "first easy and then difficult, orderly advancement, clean up, and produce results, The principle of “opening to the publicâ€, the State Railway Administration carried out the fourteenth batch of cleanup of the normative documents of the former Ministry of Railways. Among them, the "Measures for the Establishment of Railway Radio Stations and Frequency Uses" (Tieyun [2005] No. 9) continued to be effective, and all local railway companies and related enterprises were in accordance with the implementation. It is understood that the frequency of railway wireless communication allocated by the state to the railway system is: (1) Railway wireless communication frequencies in the 150, 400, and 450 MHz frequency bands for train dispatching, station shunting, and dedicated communications; (2) 2MHz frequency band construction and crossing protection frequency; (3) Frequency of 2.4 GHz railway readiness communication and emergency communication; (4) The frequency of use of the railway GSM-R system; (5) The frequency of use of the 800MHz train tail and train safety warning system; (6) Other frequencies to be used across the railway bureau (Qinghai-Tibet Railway Company). Among them, the 2.4GHz railway combat readiness communication and emergency communication frequency should be reported to the national radio regulatory agency for approval when used within the national railway. As is known to all, the railway is the national economic artery, key infrastructure and major livelihood projects. It is one of the backbone and main modes of transportation of the comprehensive transportation system. Its position and role in China's economic and social development are of paramount importance. Railway information construction has become one of the key points of the railway industry. This year, in order to promote the development of railway communications, the Ministry of Industry and Information Technology will promote the introduction of the "Regulations on Railway Radio Management" as the main point of the 2018 national radio management work. At the end of last year, the National Development and Reform Commission, the Ministry of Transport, the State Railway Administration, and the China Railway Corporation formulated and issued the "Thirteenth Five-Year Development Plan for Railways." The "Planning" pointed out that one of the objectives of railway informatization construction is to realize the intelligentization of transportation organization, accelerate the construction of the digital railway infrastructure framework based on the railway geographic information platform and serve the railway construction operation and management, and further improve the intelligent level of dispatching and commanding. Basically realize the informationization of the whole process of transportation production. It will also focus on upgrading the level of technical equipment and promoting intelligent modernization. In order to accelerate the construction of railway informationization, the railway field will speed up the upgrading of communication signal equipment, promote the miniaturization of communication signal equipment, integration and research on the next generation mobile railway communication technology, and optimize and improve the communication infrastructure network. We know that China's passenger and freight line generally adopts the combination of GSM-R wireless dispatching and wired digital dispatching, and has made great progress in technology and products. However, with the development of railway traffic and the advancement of communication technology, new requirements have been put forward for the railway command and dispatch system, which requires a transition from GSM-R to LTE-R. LTE-R can fully inherit all the services of GSM-R, and can provide users with functions such as multimedia cluster scheduling, videophone, real-time video surveillance, and passenger transportation comprehensive information release, providing railway operators with safer, easier operation and maintenance, and higher speed. Communication network. At the same time, the demand for other communication methods for high-speed and safe railway transportation is also increasing. Therefore, the advancement of railway radio management, including radio frequency and station setting management, will lay a solid foundation for the development of railway next-generation mobile communications.
