Abstract
In a geographic region that contains a trunking communication system and a cellular communication system, wherein the coverage area of each system substantially overlaps, a method that transfers a private data transmission from the trunking communication system to the cellular communication is disclosed. When a data transmission unit is prompted to transmit data, it transfers its affiliation from the trunking communication system to the cellular communication system. Once affiliated with the cellular communication system, the data transmission unit transfers its data via the cellular communication system. The trunking communication system detects the requested data and routes the requested data to the appropriate data target. Once the data transmission unit has transmitted the requested data, it transfers its affiliation back to trunking communication system.
