ABSTRACT:
A time-division multiplexed paging system for transmitting multiple paging messages on the same frequency. A geographic area is divided into a plurality of cells having base stations that transmit radio frequency signals in the cells. Each base station is assigned a time slot at which paging messages may be transmitted. The assignment is made such that no base stations having overlapping radio frequency coverage areas transmit during the same time. A locate signal is simultaneously broadcast throughout a geographic area in order to locate a paging unit. Upon receipt of the locate signal, the paging unit transmits an acknowledge signal back to the paging system. The cell in which the paging unit is located is determined based upon the signal strength of the received acknowledged signal. A paging message is transmitted from the base station in the cell in which the paging unit is located during the time slot that is assigned to the base station.
