Wireless digital personal communications system having voice/data/image two-way calling and intercell hand off provided through distributed logic
First Claim
1. A wireless digital personal communications system comprising in combination:
- a plurality of radio cell base stations, each radio cell base station having a respective radio cell coverage area, each radio cell base station comprising;
means for digital communications with a switched network via a digital network interface protocol;
means for assigning a communications channel to a specific handset terminal in the coverage area from a plurality of available communications channels; and
means for effectuating communications between the handset terminals in said radio cell coverage area and a switched network;
a plurality of handset terminals operatively disposed with said radio cell base stations, each handset terminal comprising;
means for receiving and transmitting signal messages and communications messages to one or more of the radio cell base stations;
means for selecting a radio cell base station for location registration of the handset terminal with a switched network;
means for seeking and determining an intercell hand-off from an existing radio cell base station to a second radio cell base station;
at least one switched network, each switched network operatively disposed with said radio cell base stations, each switched network comprising;
means for connecting each of the radio cell base stations to the switched network;
means for effectuating intercell hand-off from a first radio cell coverage area to a second radio cell coverage area;
means for converting the interface protocol to a second protocol for interconnection to a service control point data base; and
means for determining and accepting calls to and from a plurality of switched networks; and
a service control point data base comprising;
means for location registration of the handset terminals with at least one radio cell coverage area,said personal communications system providing intercell hand-off through distributed logic that is resident in the handset terminals, distributed logic that is resident in the radio cell base stations, and distributed logic that is resident at predetermined locations in the switched network.

Abstract
A wireless digital personal communications system (or PCS) having a plurality of intelligent base stations and portable handset terminals, each having a predetermined radio cell coverage area. The radio cell, radio-telephone PCS has a full digital network interface. The personal communications system facilitates direct interconnection and switching of PCS call traffic through the digital network interface and the public switched telephone network, or any switched network. The personal communications system has voice/data/image (or any combination thereof), and incoming and outgoing calling capability. The PCS is fully operational and compatible with any modulation approach selected. The intercell protocol hand-off being provided through distributed logic which is implemented in software that is resident in the intelligent portable handset terminals, in the intelligent base stations, and in the public switched telephone network (or any switched network).
