Abstract
The invention relates to a vehicle-mounted civil communication system for a high-speed railway, comprising an operator communication network, a ground communication subsystem and a vehicle-mounted communication subsystem, wherein the operator communication network, the ground communication subsystem and the vehicle-mounted communication subsystem are successively connected. Compared with the prior art, the vehicle-mounted civil communication system has the advantages of improving communication quality, lowering construction cost and the like.
Description
Technical field
The present invention relates to a kind of communication system, especially relate to a kind of high speed railway vehicle mounted commercial signal communication system.
Background technology
The most of intensive coverage mode of ground base station that adopts of existing high ferro circuit is realized 2g/3G call function in the compartment, because Doppler effect, car body are to factors such as signal shieldings, when speed reaches more than 350 kilometers during the train operation of high ferro, passenger's various communication equipments and ground have lost to be got in touch, the high ferro compartment forms information island, the layout dense degree of high ferro base station along the line or repeater is far longer than normal signal and covers scheme, and can't overcome owing to the problems of switching fast, Doppler effect causes such as speech quality difference.
Solving the high ferro prior art has two kinds, and the one, adopt ground base station coverage optimization scheme, intensive covering cost is big, can't solve quick switching, Doppler effect, and dropped calls often takes place, and speech quality is poor.Another is to adopt the vehicle carried mobile phone repeater scheme is installed in the car, and this scheme only solves signal strength problem, can't solve switching, Doppler effect equally, and speech quality is poor.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of high speed railway vehicle mounted commercial signal communication system that improves communication quality, reducings the construction costs for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of high speed railway vehicle mounted commercial signal communication system is characterized in that, comprises operator's communication network, ground communication subsystem and vehicle-carrying communication subsystem, and described operator communication network, ground communication subsystem, vehicle-carrying communication subsystem connect successively.
Described operator communication network comprises mobile network, UNICOM's network and communication network.
Described mobile network comprises TD-SCDMA network and GSM network.
Described UNICOM network comprises WCDMA network and GSM network.
Described communication network comprises the CDMA2000 network.
Described ground communication subsystem comprises successively network insertion controller, IP-based ground transmission and the wide bandwidth base station that connects, and described network insertion controller is connected with the operator communication network, and described wide bandwidth base station is connected with the vehicle-carrying communication subsystem.
Described vehicle-carrying communication subsystem comprises broadband car-mounted terminal, integrated access equipment, little base station and the user terminal that connects successively, and described broadband car-mounted terminal is connected with the ground communication subsystem.
Described little base station comprises moves little base station, the little base station of UNICOM and the little base station of telecommunications.
Compared with prior art, the present invention has the following advantages:
1) realizes that the passenger realizes the 2G/3G call function in the high ferro compartment, and ensure communication quality.
2) improve communication quality, for each operator saves huge construction cost.
