    摘要: A method for detecting coverage loss in a broadband wireless access system is disclosed, which recognizes a connection state between a mobile station (MS) and a base station (BS), and provides a method and apparatus for quickly performing network re-entry when the MS moves out of a coverage area of the BS. A method for allowing a base station to perform coverage loss detection of a mobile station in a broadband wireless access system includes unsolicitedly transmitting a first message wherein a bit for requesting ranging execution is set, to the mobile station, and upon receiving a second message for confirming the ranging from the mobile station prior to expiration of a first timer that begins to operate when the first message is transmitted, restarting operating a second timer established for the mobile station.

    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.
