Abstract (en)

[origin: WO2007102702A2] The present invention relates to a fast re-authentication method in a UMTS (universal mobile telecommunications system) during handover between a WLAN (wireless local area network) and the UMTS. A fast re-authentication message is added to a PMM (packet mobility management) protocol, which is a packet mobility management protocol, in the UMTS, which is a 3G mobile communication system, and a re-authentication identifier is added to the existing authentication and encryption message, which makes it possible to perform a fast re-authentication process on a mobile terminal subscriber when handover occurs between a WLAN system and the UMTS and the inside of the UMTS. Therefore, it is possible to reduce a handover delay to the minimum by supporting fast re-authentication that is capable of reducing delay due to an algorithm process for authentication and the generation of authentication vectors and keys during the handover between the UMTS and the WLAN access system.
