ABSTRACT:
In a geographic region that contains a trunking communication system and a cellular communication system, wherein the coverage area of the trunking system and cellular communication system substantially overlap and wherein some communication units are located within the geographic region, a method is disclosed for a trunking communication system to locate a particular communication unit. In order to locate a particular communication unit, a communication channel controller of the trunking communication system transmits a location request to the particular communication unit. Upon receiving the location request, the particular communication unit transfers its affiliation from the trunked communication system to the cellular communication system. Once affiliated with the cellular communication system, the particular communication unit transmits a location message to the communication channel controller via the cellular communication system. The location message received by the communication channel controller can be deciphered to determine the cell of the cellular communication system that the communication is located in.
