ABSTRACT:
A radiotelephone system allows a subscriber unit (125) to transmit above a predetermined maximum power level. The maximum power level is set at a source base-station (130) and corresponds to the maximum power level a subscriber unit (125) can transmit at without subjecting neighboring target base-stations to interference. When the received signal strength indication (RSSI) of the subscriber unit (125) as measured by the source base-station (130) falls below a transfer threshold, the radiotelephone system determines if the subscriber unit (125) is in the best sector/cell. If the subscriber unit (125) is in the best sector/cell, the subscriber unit (125) is allowed to transmit at a power level above the predetermined maximum to maintain communication to the source base-station (130).
