ABSTRACT:
A paging system comprises a base station and a number of pagers. The base station transmits calling-number data and message data in the form of radio signals. The message data contains selection-code data. Each pager indicates that the pager is being called, in accordance with the message data, when the calling-number data is identical to the calling-number data already stored in the pager. The pager comprises a calling-number data momory, a selection-code memory, a comparator, and an alarm device. When the calling-number data transmitted from the base station is identical to the calling-number data stored in the calling-number data memory, the comparator compares the selection-code contained in the message data, with the selection-code stored in the selection-code memory. When the comparator determines that the selection-code transmitted from the base station is identical to the selection-code stored in the selection-code memory, the alarm device is activated to indicate that the pager is being called. In this paging system, any pager can be called in accordance with the calling-number data and also the selection-code contained in the message data, either data having been transmitted from the base station.
