Method for performing handover in a mobile communication system

摘要

Disclosed is a method for enabling a mobile terminal to perform a handover in a mobile communication system. A serving base station which supports both a first communication scheme and a second communication scheme can transmit, to the mobile terminal, a neighbor base station list broadcast message containing time offset information indicating the point of time to transmit information on a second base station which uses the second communication scheme and supports only the second communication scheme via a specific zone using the second communication scheme. The mobile terminal which has received the message can receive, from the serving base station, the information on the second base station via the specific zone on the basis of the received time offset information.

1. A method of a mobile station (MS) performing handover from a serving-base station (S-BS) that supports a first communication scheme to a target-base station (T-BS) that supports a second communication scheme, the method comprising:
receiving an advanced air interface-neighbor-advertisement (AAI-NBR-ADV) message via an MZone of the S-BS, the MZone used for the first communication scheme and the AAI-NBR-ADV message including information related to at least one neighboring BS having an MZone and further including information related to transmission timing of a mobile-neighbor-advertisement (MOB-NBR-ADV) message to be received via an LZone of the S-BS if the S-BS supports both the first and the second communication schemes, the LZone used for the second communication scheme; receiving the MOB-NBR-ADV message via the LZone of the S-BS based on the information related to the transmission timing, the MOB-NBR-ADV message including system information related to at least one neighboring BS having an LZone that is used for the second communication scheme; scanning the at least one neighboring BS; and performing the handover to an LZone of a T-BS among the at least one neighboring BS based on a result of the scanning.
