摘要： A method for performing a handover in a mobile communication system, which is capable of independently performing an uplink handover and a downlink handover, is disclosed. An uplink channel status of a base station is checked and the uplink handover to a base station having a good uplink channel status is performed. A downlink channel status of a base station is checked and the downlink handover to a base station having a good downlink channel status is performed. Accordingly, an uplink base station and a downlink base station may be different from each other. Transmission/reception efficiency can be improved by independently performing the handover.

摘要： The present invention relates to a handover method for a mobile communication system. The handover method according to the present invention informs a current state to a serving base station(BS) when a re-entry process has been delayed or a handover has failed due to an error occurred in the handover procedure during handover, and receives from the serving BS a status information response message containing available interval and unavailable interval reset information and link disconnection time reset information for extending the link disconnection time. So, the present invention minimizes or prevents a handover delay or extend a link disconnection time with the serving BS, thereby allowing a terminal to receive a continuous service even during the handover procedure.
