Abstract: PURPOSE: A handover control method, operation method of a wireless communication terminal, and a base station are provided to control the handover process of the wireless communication terminal by referring to the history of the handover process in the base station. CONSTITUTION: When a source cell of a received handover history is matched with a cell identifier of a base station, the base station adds the handover history to handover control DB(DataBase)(S520,S540). The base station transmits the received handover history to a source cell (S530). When the added handover history is related to a wrong handover process, the base station deletes necessary records regarding to the added handover history (S550, S560).
