Abstract
A method and system for controlling the quality of handovers are disclosed in which a poor radio environment in a target cell is revealed prior to completion of the handover procedure. During the handover signalling phase, the output power of the mobile station of interest and the target cell's base transceiver station are reduced. Consequently, prior to completion of the handover, if the target cell has a poor radio environment (below a predetermined C/I or C/N), the handover attempt will fail, and the mobile station will revert and remain connected to the original cell.
