Abstract

The location independent personal telecommunications system of the present invention enables a subscriber to have a single personal telephone directory number. When that personal telephone number is dialed, the system uses the existing public and cellular communication systems and a service node all comprising parts of the personal telecommunications system to route the call to the present, or last known location of the subscriber. The location of the subscriber is determined by the personal telecommunications system through a radio tracking system comprised of a number of radio base stations that monitor the subscriber's location by communicating with a personal communicator carried by the subscriber. The subscriber location information is transmitted from the base stations to the service node for storage and subsequent access when a call is placed to the subscriber's personal telephone number. The service node will then transfer the call to the proper telephone number at the location where the subscriber is currently, or last known to be located, or if not at a fixed location with a known phone, notify the subscriber through the base stations and the personal communicator of the incoming call.
