  • Patent number: 8472392
    Abstract: The present invention relates to a WLAN virtualization system which is capable of efficiently separating a Basic Service Set (BSS) into a plurality of virtual BSSs in a Time Division Multiplexing (TDM) manner. The WLAN virtualization system includes an Access Point (AP) for providing a plurality of vBSSs, and a plurality of stations corresponding to the vBSSs provided by the AP. Each of the vBSSs is operated on a superframe basis, the superframe being scheduled by a beacon frame transmitted from the AP. The superframe includes the beacon frame, one contention-free period, and one contention period. The CPs of the vBSSs include intervals which do not overlap each other. The vBSSs can be classified into any groups designated by a service provider based on certain criteria such as physical layer, QoS, security level, or network access authority, and times can be allocated to superframes at different rates or frequencies.
