Abstract
A method for sharing a common receiver between a cellular telephone and a pager such that selectively tuning the receiver to receive cellular telephone system frequencies and pager system frequencies allows simultaneous operation as a cellular telephone and pager during periods when both devices are in sleep mode. The method includes prioritizing operation of one of the devices, anticipating the occurrence of both cellular system paging channel transmission and pager system paging channel transmission, and tuning the common receiver to the appropriate frequency band.
