ABSTRACT:
A wireless LAN system if formed by a base station, mobile stations and a controller. The controller receives a frame over wireless media, and a frame analyzer analyzes the received frame. A determination section determines whether or not the frame received at a predicted time based on the rule of frame for a service on a layer higher than a media access control layer is an intended frame based on results from the frame analyzer. A frame transmitter sends out a frame containing a field specifying the duration of the frame to be transmitted to a destination station that should be given the first priority to transmit on a wireless uplink and downlink, based on the determination that the frame received is not in conformity with the rule of frame.
