Abstract
An on-board unit includes a first antenna and a second antenna, a traffic data service communicating section corresponding to a traffic data service; a billing service communicating section corresponding to a billing service, a switch which switches a connection relation between each of the first antenna and the second antenna and the traffic data service communicating section and the billing service communicating section, a control section which controls the switch. When the operation mode is switched from the traffic data service mode to the billing service mode, the on-board unit is set to a switching communication mode in which one of the first antenna and the second antenna is connected with the traffic data service communicating section and the other is connected with the billing service communicating section.
