  • Publication number: 20060268715
    Abstract: In a wireless communication system comprising a plurality of mesh points (MPs), a method and apparatus for transmitting management information includes a first MP transmitting a management frame to a second MP, wherein the management frame includes the medium access control (MAC) address of a destination MP. The second MP receives the management frame from the first MP and determines if it is the destination MP. The second MP updates the management frame if the second MP determines it is not the destination MP, and transmits the management frame to a third MP. The transmissions terminate when the data reaches the destination MP.

  • Publication number: 20060246904
    Abstract: A method for generating a media independent handover (MIH) trigger in a wireless local area network begins by sending a measurement report request message to a measurement entity in the network. The measurement entity takes the measurements and sends a measurement report response message to a medium access control (MAC) function. The MAC function evaluates the measurements and determines whether a handover condition exists, based on the measurements. The MAC function generates a MIH trigger if the handover condition exists.

  • Publication number: 20060227726
    Abstract: In a wireless local area network including an access controller (AC) and an access points (AP), the AC transmits a functionality inquiry to the AP. Upon receiving the inquiry, the AP transmits a query response including the functional capabilities of the AP. The AC then generates a map of the functional capabilities present in the network based on the inquiry response. Conflicting or redundant functional capabilities are identified and are disabled, enabled, or reconfigured by instructions from the AC. The AC may selectively enable and/or disable functional capabilities at nodes in the network to provide a more balanced load on the network, and to provide for load sharing by allocating functionalities between and among network nodes having common functional capabilities to satisfy a variety of situations encountered in the network.
