ABSTRACT:
Disclosed is a method for fast handover in a wireless security data communication environment. The fast handover method for a mobile node connected to a network via an access point to perform a data communication in a wireless communication environment according to the present invention includes: performing an authentication while communicating with an authentication server having registration information about the mobile node via an uncontrolled port of the access point so as to make the mobile node connected to the network; performing a mobile Internet Protocol (IP) registration for binding a Care-of-Address (CoA) to a home agent and a correspondent node (CN) via the access point in parallel with performing the authentication; and opening a control port of the access point and relaying data transceived at the mobile node using the CoA when the authentication and the registration being successfully completed. Accordingly, a fast handover of the mobile node can be supported.
