HIGH SPEED HANDOVER METHOD AND A SYSTEM OF THE SAME IN A WIRELESS LAN HAVING A PLURALITY OF MOBILITY DOMAIN, CAPABLE OF PERFORMING HIGH HANDOVER IS CASE OF MOVING TOWARD TO AIM ACCESS POINT OF DIFFERENT MOBILITY AREA FOR A MOBILE TERMINAL THROUGH PRELIMINARY AUTHENTICATION PROCESS

摘要

PURPOSE: A high speed handover method and a system of the same in a wireless LAN having a plurality of mobility domain are provided to reduce hand over delay time by authentication process when performing handover to access point of different mobility area for various mobile terminals.;CONSTITUTION: A sockets interface(610) transfers the AP(Access Point) information between a mobile terminal and an authentication server. An AP scanning module(620) scans the APs of the corresponding area. A probe message confirmation unit(630) performs the parsing of the probe message of the AP scanning module. An AP list confirmation unit(650) extracts the movable AP information. A pre-authentication ID generation unit(660) request pre-authentication to target AP among AP information.;COPYRIGHT KIPO 2010
