Personal phone number system
First Claim
1. A Personal Communication System (PCS) comprising:
- a cellular telephone network having cellular call forwarding capabilities to a landline telephone communication network;
a base station connected to the landline telephone communication network, said base station including,a transceiver for communicating with a portable subscriber station over cordless telephone frequencies,a means for detecting when a selected portable station is within range of said transceiver, anda means for requesting activation of the cellular call forwarding by the cellular telephone network when the selected portable station comes within range of said transceiver;
at least one portable subscriber station having a personal phone number (PPN), said portable subscriber station including,a first transceiver for communicating with said base station over cordless telephone frequencies, anda second transceiver for communicating with said cellular telephone network;
wherein, when the subscriber station comes within range of the base station transceiver operating at cordless frequencies, the base station initiates a wireless transmission causing a cellular call forwarding message to be transmitted over a cellular signaling channel to activate call forwarding of incoming calls for the PPN via a landline to the base station.

Abstract
A Personal Communication System (PCS) is operated using a Personal Phone Number (PPN) associated with each portable subscriber station within the system. Each portable subscriber station has an associated "home" cordless telephone base station associated therewith. When a particular portable subscriber station is within a range of its home base station, that base station controls the transmission of a cellular call forwarding request to a cellular telephone system servicing that area. The cellular telephone function of the portable subscriber station is deactivated, and all incoming calls addressed to that particular PPN are routed over a telephone landline connected to the associated cordless telephone base station servicing the portable subscriber station. Upon leaving the range of communication of the associated cordless telephone base station, the portable subscriber station reactivates its own cellular telephone function so that communication can be carried out with the cellular telephone system servicing that area.
