Abstract
PURPOSE: To set up the direct trunk exclusive for the necessary period between the control station and the specified terminal station in the system of the multi-channel radio communication which is constituted with the control station and several terminal stations.
CONSTITUTION: Transmitter/receuver TRX1∼TRXn are installed at control station MS corresponding to several channels CH1∼CHn featuring different frequency waves. And an optional idle channel, for example, CH1 is selected for the holding channel at station MS, and holding signal SS is transmitted from signal transmitter SSm. At the same time, the idle signals are transmitted to other idle channels CH2∼CHn from transmitter SSm. Then at each terminal station TS, the idle signals are detected to have switching to the holding channel. In case the direct trunk is set up due to an emergency state, both designation signal Sc1 and circuit setting signal S are transmitted from holding channel CH1. And these transmitted signals are detected at designated terminal TS to send back the answer signal. Thus a direct trunk is completed between stations MS and TS to be then held, and the holding channel is switched to other channels.
