Provided is a mobile communication system in which a road-side device (2) distributes, using a control channel, a WSA that includes target vehicle information indicating an area (service provision area) in which a service is to be provided. When a vehicle-mounted device (1) receives the WSA, a service coverage determination unit (F5) determines, on the basis of the positional relationship between the current location of the vehicle-mounted device (1) and the service provision area indicated in the WSA, whether or not the vehicle-mounted device (1) is covered by the service provided by the distribution source. When it is determined by the service coverage determination unit (F5) that the vehicle-mounted device (1) is not a vehicle-mounted terminal that is covered by the service, the vehicle-mounted device (1) does not start communication with the distribution source which uses a service channel. |
