Method for automatic transceiver selection in a mobile multiple rf transceiver apparatus

摘要

A multi-radio equipment arrangement provides mobile radio users with the ability to operate with multiple transceivers of different band splits. A preferred arrangement utilizes at least one transceiver operating on a digital "trunked RF" communications system and at least one transceiver operating on a wide-area "conventional RF" communications system. The transceivers communicate with a control unit and each other via a common bus to form a multi-radio local network. One radio is predefined as the "master" radio and is provided with a master interface task routine. The master task software manages serial communications on the multi-radio bus and also includes an auto-select control task (ASCT) routine that determines which transceiver equipment should currently be selected for providing RF communications. The ASCT also implements a radio roaming feature that automatically switches back and forth between two or more trunked communication system transceivers depending on the audio quality available on each system and a preference selected by the mobile user.
