Method and system for road vehicle communication

摘要

A road vehicle communication method allows bothway communication to be held between a mobile station (106), which sends a request for an information service and receives it, and a central base station (204) and local base stations (206-210) located at a roadside for sending the information service to the mobile station (106). The central base station (204) and the local base stations (206-210) use optical fibers in part of the transmission path thereof for the bothway communication and perform at least one of electric-to-optical conversion and optical-to-electric conversion. The mobile station (106) is caused to send the request for an information service beforehand. In response to the request, the local base station (206/208/210) covering the mobile station (106) expected to receive the information service is estimated. When the mobile station (106) lies in a service area (214/216/218) to which the local base station estimated is assigned, a control station (202) is caused to provide the mobile station (106) with information corresponding to the information service requested.
