PURPOSE:To omit the normal contract procedure and to facilitate use of a pager by calling the pager after a radio call switchboard refers to a data storage part and then confirming the available period and the calling frequency of the pager. CONSTITUTION:When a specific pager call requester transmits a call through a telephone set 5, a radio call switchboard 2 refers to 8 data storage part to decide the aveilable period of a pager 1 having its limited period and using frequency. If an invalid period is decided, the expiration of the available period is informed to the caller. If a valid period is decided, the usable remaining value is confirmed. If this value is larger then a prescribed level, the pager 1 is called out via an area controller 4 and 8 radio transmission base station 3. Meanwhile the pager 1 is called out in a tone different from normal ringing tone if the usable remaining value is smaller then a prescribed level. Then expiration of the usable frequency is informed to the caller if the usable remaining value is equal to zero. In such a constitution, the paging service is ensured with no contract procedure. Then the use of the pager 1 is facilitated. |
