RAIL TRANSIT COMMUNICATION METHOD AND SYSTEM

摘要

A rail transit communication method and system, the method comprising: when a target free space optics (FSO) base station carries out data communication with a target user terminal by means of a first target FSO transceiver, if monitored that the first target FSO transceiver has moved out of the signal coverage range of the target FSO base station, screening one FSO transceiver from all of the FSO transceivers which are still currently located within the signal coverage range of the target FSO base station to serve as a second target FSO transceiver, the target FSO base station being any one FSO base station located on a rail; and using the second target FSO transceiver to continuously maintain a data communication process between the target FSO base station and the target user terminal. With the present application, the base station switching frequency of user equipment may be reduced, and the data communication rate is increased, thereby improving the communication experience of a passenger.
