APPARATUS AND METHOD FOR PERFORMING A HANDOVER IN A WIRELESS COMMUNICATION SYSTEM

摘要

Provided is a method for performing a handover in a wireless communication system including a macro base station and a femto base station. The method comprises the steps of: monitoring an uplink signal transmitted from a user equipment to the macro base station; transmitting a handover request message to the macro base station on the basis of the result of the comparison between the intensity of the uplink signal obtained from the monitoring performed in the previous step and a reference value; and performing a handover for the user equipment from the macro base station to the femto base station. The present invention proposes a detailed method for enabling the femto base station to search for user equipment existing in the cell coverage thereof and to induce a handover, and utilizes preexisting information such as uplink transmitting power to reduce signaling load.
