Abstract

The present invention relates to a fast handover method in a wireless LAN, and to a mobile terminal adopting the same. The handover method comprises the steps of (a) determining a handover, and transmitting an authentication request message to a target access point, if the intensity of the signal received from the current access point is lower than a preset first threshold value (T1); (b) determining whether or not to apply a reauthentication request module in accordance with the set user profile; (c) driving a timer, if the reauthentication request module is applied in accordance with the result of the determination of step (b); (d) receiving an authentication response message from the target access point; (e) performing a reauthentication process with the target access point if the time counted by the timer has elapsed past the preset reauthentication request time and the handover has not been carried out; and (f) performing a procedure for reaccess to the target access point if the handover to the target access point is performed within a limited reaccess time. The present invention makes a request for reauthentication if a handover does not occur within the limited reaccess time, thereby providing a fast handover.
