First Claim
1. A system for jointly operating a first wireless communication device and a second wireless communication device where the first wireless communication device and the second wireless communication device share a common receiver comprising:
- means for prioritizing operation of either the first wireless communication device or the second wireless communication device;
means for anticipating occurrences of the first wireless communication device paging channel transmissions and of the second wireless communication device paging channel transmissions;
means for tuning the common receiver to the first wireless communication device paging channel transmission during the anticipated occurrence of the first wireless communication device paging channel transmission and to the second wireless communication device paging channel transmission during the anticipated occurrence of the second wireless communication device paging channel transmission when no overlap exists between the first wireless communication device paging channel transmission and the second wireless communication device paging channel transmission;
means for tuning the common receiver to the first wireless communication device paging channel transmission during the anticipated occurrence of the first wireless communication device paging channel transmission when operation of the first wireless communication device is prioritized and an overlap exists between the first wireless communication device paging channel transmission and the second wireless communication device paging channel transmission; and
means for tuning the common receiver to the second wireless communication device paging channel transmission during the anticipated occurrence of the second wireless communication device paging channel transmission when operation of the second wireless communication device is prioritized and an overlap exists between the first wireless communication device paging channel transmission and the second wireless communication device paging channel transmission.

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.
