A wireless LAN(WLAN) and a method for implementing a mobile terminal's fast handover, the WLAN comprises mobile terminals and access points(Ap) which accesses mobile terminals to the network, each AP and the mobile terminals associated with it form a basic service set(BSS), between the mobile terminals and the Aps, utilizing the cryptographic material which is associated with the BSS identification to protect the air interface; wherein, a plurality of physical Aps form a logic AP and share the same basic service set identification(BBSS-ID), when the mobile terminals handover between a plurality of Aps, it uses directly the cryptographic material which was associated with the BSS identification before handover to protect the air interface. Meantime, the present invention also discloses a wireless LAN. |
