Wireless digital personal communications system having voice/data/image two-way calling and intercell hand off provided through distributed logic

摘要

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).
