Abstract

In-vehicle terminal (11, 11a) installed on a vehicle (10) and performing wireless communication with a plurality of base stations via a plurality of paths, the in-vehicle terminal (11, 11a) comprising: a vehicle-to-vehicle communication control unit (41) for controlling communication with a neighboring vehicle located near the vehicle (10) and capable of vehicle-to-vehicle communication; a neighboring vehicle information management unit (42) for managing neighboring vehicle information, comprising position information of the neighboring vehicle and information about the communication status of the vehicle-to-vehicle communication obtained through the vehicle-to-vehicle communication; a base station communication control unit (44) for performing control to a first base station (30; 30a;30b), which is the base station connected via direct communication, to provide information about a second base station (31; 31a; 31b), which is the base station that cannot be connected via direct communication, and to request the first base station to provide connected terminal information, which is information about the adjacent vehicle connected to the second base station (31; 31a; 31b); a relay management unit (46; 46a) to hold the connected terminal information obtained from the first base station (30; 30a; 30b) and to select a relay station, which is the adjacent vehicle, to forward indirect communication with the second base station (31; 31a; 31b) based on the adjacent vehicle information and the connected terminal information; and a redundant system management unit (45) for managing a connection with the first base station (30; 30a;30b) and the second base station (31; 31a; 31b) and to instruct the relay management unit (46; 46a) to perform indirect communication with the second base station (31; 31a; 31b) when the second base station (31; 31a; 31b) cannot be connected via direct communication.;
