PURPOSE:To detect whether error exists or not by comparing a transmission message and a response message with each other in the base station. CONSTITUTION:When a message is transmitted to mobile terminal C by the operation of operation board 1 of general subscriber A, base station B stores temporarily the message in memory and control part 2. When discriminating that the message is directed to mobile terminal C, mobile terminal C transmits automatically the received message to base station B after a prescribed time. Base station B compares the transmission message and the response message with each other in comparator 6; and if they agree with each other, it is reported to subscriber A to display transmission end on display equipment 8. If they do not agree with each other, the same message is transmitted from transmitter 3 again. If they do not agree with each other regardless of n-time re-transmission, it is reported to subscriber A to display it on display equipment 7 and terminate communication. |
