1. A wireless telephone system, comprising:

  • a plurality of cell-sites, each cell-site having a base-station and a number of mobile-subscribers linked to said base station;

    a central adjunct node-processor linking together said plurality of cell-sites, and controlling all call-processing functions and operations between said plurality of cell-sites;

    said adjunct node-processor comprising a computer having memory means for storage of data;

    said memory means comprising control means for controlling call-processing of a telephone call between mobile subscribers;

    said memory means comprising objects-oriented software comprising a state table defining all of the possible states for call-connection to a said cell-site, and objects-directed software means for creating pointers for said state stable;

    said plurality of cell-sites comprising at least two different cell-sites operating on different specifications and protocol, said objects-oriented software linking together said at least two different cell-sites, whereby cell-sites of different specifications and protocols may be linked together by said central adjunct node-processor;

    whereby different cell-sites operating on different specifications and protocol may be subsequently coupled to said central adjunct node-processor via said memory means using the existing hardware elements, so that existing hardware elements need not be replicated in order to accommodate different cell-sites operating on different specifications and protocol.
