Abstract

The invention provides a vehicle-mounted wireless communication control method, device and system, and is used for overcoming at least one of the disadvantages of low utilization efficiency of frequency spectrum, poor network redistribution capacity and poor communication connection flexibility in the prior art. The method comprises the steps that network information of a vehicle-mounted network and / or network information of a driving rail side wireless tracking transmission network are acquired; and at least one of the following operation is performed by using at least one network information: rail identification; initial access control; radio frequency receiving / transmitting array reselection control; space reuse frequency control; control of sharing RF node arrays between the rails; transmission control of wireless access points; and transmission control of a driving controller. The device and the system have the advantages of high frequency spectrum efficiency, high fault tolerance and flexible configuration and can be used for business transmission of passengers and can also be used for train driving control.

Description

technical field [0001] The present invention relates to the field of transportation, in particular to a vehicle wireless communication control method, device and system. Background technique [0002] Currently, high-speed railways and subways / city rails use existing cellular mobile communication networks to provide communication services to passengers. High-speed railways are characterized by fast movement speed and high user density. The resulting problems are: high-speed movement reduces the transmission efficiency from vehicle-mounted terminals to ground base stations or leads to dropped calls; high user density makes it difficult for cellular mobile communication capacity to meet passenger needs Actual demand. For the subway / urban rail, since the moving speed is lower than that of the high-speed rail, the reduction in the transmission efficiency from the vehicle-mounted terminal to the ground base station is smaller than that of the high-speed rail. However, the capacit...
