Abstract

See full text

The instant invention discloses a method and system for providing a novel wireless centrex service that untethers subscribers from the immobility associated with traditional desktop telephones. Essentially, the present invention extends the benefits of wireless voice and data services to subscribers having a need to move within a plurality of localities such as business and hospital campuses. In accordance with the invention, a wireless telephone subscriber can use a standard cellular/PCS telephone as a wireless extension of their desktop phone, while in the proximity of a miniature radio base station capable of communicating with the PCS/cellular telephone. The advantage of such a system is that a subscriber can use the same cellular/PCS telephone that provides service in the public network in the wireless centrex environment. Additionally, the wireless centrex system provides services and features which are similar to those offered to regular centrex telephone subscribers. Exemplary features include, caller ID, call waiting, call hold, call transfer, call forwarding and voice messaging.
