CONSTITUTION: After approaching a roadside base station B and receiving requested information, a DSRC loading device transmits an information processing request to an ITS(Intelligent Transport System) center server(13). In this case, the roadside base station B is appointed as a processing request part roadside base station(11). In case that the processing request part roadside base station(11) cannot process a processing result independently, the base station(11) transmits the information processing request, which the roadside base station B will receive the processing result, to the ITS center server(13). The ITS center server(13) calculates the processing result for the processing request. Then the ITS center server(13) transmits the result to the roadside base station B and waits until the loading device approaches. If the loading device approaches the communication service area of a processing supply part roadside base station(12), the loading device retransmits the request for the information processing result. The processing supply part roadside base station(12), receiving the request, transmits the prepared processing result.
