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 method for creating sub-networks in a wireless mesh network begins by determining whether a trigger condition for creating a sub-network exists. Nodes in the mesh network are selected to create the sub-network if the trigger condition exists. The sub-network is then created with the selected nodes. A node for use in a wireless mesh network includes a state device for maintaining a state of the node, the state of the node relating to activity occurring at the node; an attachment list communicating with the state device; a trigger device communicating with the state device; and an attachment device communicating with the attachment list and the trigger device

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 (502) to a measurement entity (502) in the network. The measurement entity takes the measurements and sends a measurement report response message (522) to a medium access control (MAC) function (504). The MAC function (504) 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.

Abstract: A method for communicating a list of handover candidates in a wireless local area network from a station to a serving access point (AP) begins by determining a list of handover candidate APs at the station. The candidate list is sorted at the station and is sent to the serving AP. The sending step can include sending the candidate list to the serving AP upon the expiration of a predetermined period of time or upon receipt at the station of an event trigger. The method can also include the step of requesting a candidate list from the station by the serving AP.

Abstract: The present invention relates to a method for confirming the delivery of a data packet in a mesh network (100) by sending an acknowledgement to an ingress mesh point (104-4). A mesh network (100) comprises a plurality of mesh points (104) that are wirelessly linked together. A data packet sent by a station is received by an ingress mesh point (104-4). A MAC frame (200) is generated for transmission of the data packet and the frame is forwarded to an egress mesh point (104-2) in order to provide a service by the mesh network. The MAC frame (200) includes a field comprising an ingress mesh point address (206) and an egress mesh point (208) address. When the egress mesh point (104-2), receives a data packet successfully, the egress mesh point (104-2) or the intermediate mesh point (104-5) sends an ACK to the ingress mesh point (104-4) or preceding mesh point.

Abstract: The method involves transmitting a network status request signal from a mesh point (MP) to another MP, where the later MP responds to the former MP with the network status information. The information is received by the former MP from the later MP. A level of involvement in the wireless communication system is determined based on the received information. The status information includes an availability of other MPs in the system, availability of an external network, average and peak delays in the system, bandwidth availability, and the number of other MPs in the system.

Abstract: A wireless communication system including a mesh network having a plurality of mesh points (MPs), a plurality of wireless transmit/receive units (WTRUs), extra-mesh local area network (LAN) resources, and an external network is disclosed. When one of the MPs receives a packet, a determination is made as to whether the received packet is destined to another MP belonging to the same mesh network, (or to a WTRU served by another MP), and, if so, a determination is made as to whether there are at least two mesh portals in the mesh network that provide access to the external network via the extra-mesh LAN resources. The packet is routed according to an intra-mesh routing algorithm if there are less than two mesh portals in the mesh network. Otherwise, a determination is made as to whether an extra-mesh routing algorithm or an intra-mesh routing algorithm should be used.

Abstract: A startup process of an access point (AP) includes a discovery phase and an announcement phase. During the discovery phase, the AP detects neighboring APs from its own extended service set (ESS), neighboring APs from different ESSs, and external sources of interference. During the announcement phase, the AP transmits its beacon signals at maximum power in order to accelerate recognition by neighboring APs running the discovery phase. An automatic initialization channel selection process of an AP scans channels the AP will use to communicate. Information of each scanned channel is recorded and a best performance channel is determined for use by the AP.
