Filed: 2002-12-02
Abstract: PURPOSE: A method for automatically updating a neighbor list in a CDMA communication system is provided to enhance a success rate of handoff by adding a handoff-failed PN(Pseudo Noise) on a neighbor list. CONSTITUTION: A CCP(Call Control Processor) of a BSC(Base Station Controller) generates neighbor PN statistics information and periodically reports it(S10). The BSC determines whether the generation neighbor PN statistics list includes a handoff-failed PN and checks the handoff-failed PN(S20). The BSC determines whether the handoff-failed PN is on a neighbor list transmitted from the BSC to a mobile terminal(S30). If the handoff-failed PN is not on the neighbor list, the BSC adds the handoff-failed PN to the neighbor list(S40). If, however, the handoff-failed PN is on the neighbor list, the BSC checks how many times the handoff-failed PN has attempted handoff(S50). If the handoff-failed PN has attempted handoff many times, the BSC grades up a neighbor list extract priority level of the handoff-failed PN(S60).
