METHOD AND AN APPARATUS FOR GENERATING A HANDOVER NEIGHBOR LIST IN A CELLULAR MOBILE COMMUNICATION SYSTEM, PARTICULARLY FOR REDUCING AN OVERHEAD ACCORDING TO CELL SEARCH IN PERFORMING HANDOVER BY DETERMINING A PRIORITY LEVEL OF A NEIGHBOR LIST BY REFLECTING ACTUAL HANDOVER STATISTICS DATA

摘要

PURPOSE: A method and apparatus for generating a handover neighbor list in a cellular mobile communication system are provided to increase operational convenience by providing operator's screens for performing a function of extracting a handover priority level and reflecting a neighbor list. CONSTITUTION: A URM(UMTS RAN Manager) collects statistics information on handover to different target base stations periodically or when a condition is satisfied from each base station and stores it(110). When a user requests generation of a neighbor list with respect to a particular base station(120), a priority level reference is selected according to the user's request(130). The URM determines a priority level of target base stations in order starting from the largest handover attempt count or in order starting from the highest handover success rate(140). A neighbor list is generated including certain number of target base stations in order starting from the highest priority level.
