Abstract
To avoid interference with the reverse link of a base station within an underlay area, a described method determines when to redirect and handover a mobile terminal that is still communicating on an adjacent carrier with a border base station within an overlay area but is within the coverage area of the base station in the underlay area. The method determines that redirection and handover to the base station in the underlay area should occur when together: (1) the power being received on the downlink from the base station in the underlay area exceeds the power being received on the downlink from the border base station within the overlay area by a first predetermined threshold that indicates that the mobile terminal is at the border of the overlay area; and (2) the sum of the power being received on the downlink from the underlay base station plus the power of the signal being transmitted by the mobile terminal to the base station within the overlay area is greater than a second predetermined threshold that indicates that the power being received by the base station in the underlay area from the transmitting mobile terminal can interfere with the operation of that base station.
