PURPOSE:To improve the reliability of charging control by sending information on the acceptance of money to a center side on on-hook operation and in the next originating call. CONSTITUTION:As a mobile public telephone set 1 originates, a mobile telephone switcheboard 3 sends the indication of the transmission of current money acceptance information after the last call ends to the mobile public telephone set 1. The mobile public telephone set 1 sends the acceptance information to the mobile switchboard 3. However, when the acceptance information is sent on the completion of the last call, a ''0'' is sent and then normal calling-subscriber corresponding charging metering is performed. On the completion of a call, the accpetance information is sent from the mobile public telephone set 1 in succession to a control signal. If a signal confirming the transmission and reception of the acceptance information is not understood on either side, and the call ends abnormally, the current acceptance information is sent in the next calling. |
