System and method for private network coverage of railway

Abstract

The invention provides a system for private network coverage of a railway. The prior communication network wireless subsystem and satellite communication subsystem are effectively combined to construct a private overlay network based on an on-vehicle base station; the communication network subsystem comprises the on-vehicle base station, a gateway and a base station controller; and the on-vehicle base station realizes connection with the base station controller in a communication mode through the gateway and the satellite communication subsystem. Accordingly, the invention also provides a method for private network coverage of the railway. The on-vehicle base station is arranged in a carriage of a train, and not only can improve the signal intensity in the carriage, but also can make the base station and users in a relative rest state during high-speed running of the train, thereby solving the problems of signal attenuation and deterioration caused by factors such as carriage shielding, Doppler shift and the like, and ensuring to provide high-quality services of communication service such as voice, data and the like for the users on the train.

Description

Technical field [0001] The invention relates to the field of wireless communication, in particular to a system and method for railway private network coverage. Background technique [0002] GSM (Global System for Mobile Communications, Global System for Mobile Communications) is the most widely used communication system in mobile communications. So far, it has served nearly 2 billion users worldwide and is still growing rapidly. It is estimated that in the next 3 to 5 years, or even 10 years, GSM will still be one of the mainstream mobile communication methods. [0003] Traditional GSM network GSM network wireless subsystem 10 such as figure 1 As shown, it includes three parts: a base station controller (BSC, Base Station Controller) 101, a base station (BTS, Base Transceiver Station) 102, and a mobile terminal (MS, Mobile Station) 103. The base station controller 101 and the base station 102 are defined as an Abis interface. The Abis interface can be based on IP or TDM (Time Di...
