The method provides talk around in the communication system by sending a talk
around request from one of the subscriber units 101-108 to the base unit
100. At the subscriber unit a RSSI (received signal strength indication)
of a signal received from the base unit is determined and sent back to the base
unit 100. In the base unit 100 the RSSI is compared to a predetermined
window. If the RSSI is above the window, the request from the subscriber unit is
denied. If the RSSI is within the window, a frequency channel and power level are
assigned to the subscriber unit, the subscriber unit thereby going into talk around
mode. If the RSSI is below the window, the subscriber unit does not respond and
the subscriber unit goes into a direct communication mode independent of the communication system.
