球局２へ送り出す。In this case, the ship side telephone terminal device 5 transmits a prefix code for requesting immediate telephone charge and the telephone subscriber number of the land side telephone terminal device 13 as a dial signal. The dial signal is transmitted to the satellite 1 via the wireless device 6 via the antenna 7 via a radio carrier. The satellite 1 converts the channel of the radio carrier and sends it out to the coast earth station 3. The coast earth station 3 extracts a dial signal from the wireless carrier received by the wireless device 9 via the antenna 8 and sends the dial signal to the exchange 10. The exchange 10 recognizes the request for immediate notification of the telephone charge based on the prefix code included in the received dial signal, analyzes the telephone subscriber number included in the dial signal, and converts the analyzed telephone subscriber number into the domestic communication network. 12 to establish a connection with the land side telephone terminal device 13. And the exchange 10
While monitoring a disconnection signal transmitted upon completion of a call between the caller and the called party, call time and minute information and telephone charge information relating to telephone communication between the caller and the called party. To
The calculation is performed by the billing system 11. And exchange 10
Transmits the call time and minute information and the telephone charge information calculated by the billing system 11 to the satellite 1 via the wireless device 9 via the antenna 8 on a wireless carrier. The satellite 1 converts the channel of the radio carrier and sends it out to the ship earth station 2.
