摘要
In data communication utilizing a radio transmission channel, even in a case where the radio channel is disconnected and a data communication blackout occurs, the center side continues data communication processing, by obtaining information on a period where the data communication is interrupted in advance. The system comprises an application server provided in the center, a radio data communication terminal that performs data communication while moving, a mobile gateway provided in the center as a relay device between the application server and the radio data communication terminal, and a period notification device that transmits period information T at predetermined periods. The radio communication channel is disconnected by the period information transmitted from the period notification device, and the mobile gateway performs communication processing during the radio communication disconnection.
