ABSTRACT:
Control circuitry and an associated method for a modified-user, wireless communications system, such as a cellular communication system wherein groups of mobile transceiver units are positioned to travel together. Circuitry is positioned to travel together with the group of mobile transceiver units and to generate common control requests to control operation of the entire group of mobile transceiver units. When embodied in a cellular communication system, a common hand-off request is generated for the entire group of mobile transceiver units, obviating the need for each transceiver unit to independently generate a hand-off request. If a mobile transceiver is operable pursuant to an air interface standard dissimilar to a fixed-site transceiver with which communications are to be effectuated, a converter converts communication signals so that the communication signals can be communicated therebetween.
