PURPOSE:To reduce a load on a satellite line control station and to improve the completion ratio of a satellite system, by measuring the completion ratio of a call which requests a satellite line, and preventing the inflow of an invalid call to the satellite system or an incoming gate exchange from being generated by closing the line of a gate exchange on a call issuing side, or changing the classification of the line. CONSTITUTION:Each of the gate exchanges 1 and 2 calculates the completion ratio based on the total number of calls and the total number of response calls of a satellite system traffic file 14 periodically, and when the completion ratio is smaller than a set value, closes an output side line so as to match to the completion ratio, or changes the line classification of a direction classified line file 15 to input only. At this time, it is not required to rewrite the gate exchange file 20 of the satellite line control station 5. Also, the completion ratio is calculated based on the total number of calls and the total number of response calls at every incoming gate exchange in an outgoing gate exchange, and when the completion ratio is smaller than the set value, busy display is set at every incoming gate exchange. As a result, when the completion ratio exceeds an on-going value, the autonomous operation of a system can be guaranteed by returning a state to an initialized state. |
