Title: MOBILE OBJECT COMMUNICATION SYSTEM FOR, AND MOBILE OBJECT-SIDE DEVICE
Abstract:
A mobile object communication system (100) is provided with: a roadside apparatus (1) that provides a predetermined service to a vehicle-side device (3) by carrying out WAVE communication with the vehicle-side device; and a wide-area-mediated provision unit (221, 123) that provides a service having the same content as that of the roadside apparatus by carrying out wide-area communication with the vehicle-side device. The vehicle-side device has the capacity to carry out WAVE communication and wide-area communication, and has a communication propriety determination unit for determining whether it is possible to carry out WAVE communication with a roadside apparatus that will provide a service to be used next. If the communication propriety determination unit determines that it is not possible to carry out WAVE communication with a roadside apparatus that is providing a service being used next, a service having the same content is used by carrying out wide-area communication with the wide-area-mediated provision unit.
