Abstract: PURPOSE: A mobility management method in a cellular mobile communication system is provided to reduce unnecessary handover procedures and handover failure number by controlling a handover priority. CONSTITUTION: A second base station measures the dwell time of a terminal which hands data over from a first base station to a second base station(S310). In case the dwell time is lower than a predetermined threshold value, the second base station transmits messages including the dwell time to a first base station(S320). The first base station accumulatively manages one or more information. A handover candidate priority for the first and the second base station is changed based on the accumulated information(S330).
