Abstract: A method and apparatus for communicating slot allocations of nodes in a wireless mesh network that has data exchanges between the nodes occurring during slots. Each node maintains internal tracking of its slot allocation. A node may request a slot allocation of another node, and each node is enabled to report its slot allocation to other nodes. An information element (IE) and management type messages are introduced for tracking and reporting slot allocations among mesh network nodes.

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 capa¬bilities to satisfy a variety of situations encountered in the network.

Abstract: A device for identifying an emergency call in a wireless local area network includes an indicator to identify a call as an emergency call. The indicator can be a bit flag or an information element. The information element can include location information regarding the location of the station that placed the emergency call. This information can be used to locate the caller. The location information can be transmitted from the station to an access point separately from an emergency call.

Abstract: A wireless communication system including at least one IEEE 802 multi-stack wireless transmit/receive unit (WTRU) and a plurality of technologically diversified access networks, such as IEEE 802.X networks and Third Generation Partnership Project (3GPP) networks, that are concurrently deployed, Both the multi-stack WTRU and the technologically-diversified networks include a media independent handover (MIH) function.; The WTRU is configured to read MIH information transmitted from one of the IEEE 802.X networks, trigger 3GPP authentication and authorization procedures based on the MIH information, obtain a local Internee protocol (IP) address, establish a tunnel to a packet data gateway (PDG) in a 3GPP core network, construct a care of address (CoA) and register the CoA with a home agent of the WTRU, whereby data destined for the WTRU is routed via the home agent through a new tunnel established between the home agent and a foreign agent based on the CoA.

Abstract: Un Método para controlar el comportamiento de los enlaces de capa inferior relacionados a la transferencia de control independiente de medios (MIH) de un usuario móvil comprende enviar una solicitud de acciones de enlace MIH primitivo de una entidad de Usuario MIH a una función de MIH (MIHF) para solicitar que las acciones sean ejecutadas en un grupo de enlaces de capa inferior para redes de tecnología de acceso de radio heterogéneo (RAT). Lo primitivo incluye parámetros que indican las acciones solicitadas y un retraso de tiempo de ejecución. Los primitivos de confirmación se envían de regreso a la entidad de Usuario MIH para transportar los resultados de los intentos de ejecución sobre las acciones solicitadas.
