Abstract

PURPOSE:To prevent the double transmission of a message at a line trouble time by transmitting a serial number, in which a question response is completed, and the serial number to be just processed between transmitting side and receiving side systems after a line trouble is recovered. CONSTITUTION:After the line trouble is recovered, a transmitting side system 100 transmits a serial number questioning message 100 of a serial number X to be just processed at that time (a serial number under processing) and a successive number Y in which the question response is completed (a completed serial number) to a receiving side system 200. Then, to this operation, the system 200 transmits a serial number responding message 12 of a processing serial number Z at that time and a completing serial number W to the system 100. Thus, the system 100 judges the processing condition of the message in the system 200 at the line trouble time and executes a necessary processing. For example, in case of an index number 1 of a figure, the system 100 re-sends the message of n+1 and in case of an index number 2, the system 100 waits for the response of n+1 from the system 200.
