    Abstract: A method and system wherein handover information is broadcast in a wireless local area network. Handover information is broadcast in a beacon frame thereby allowing WTRUs operating in a wireless area network to handover to available alternative systems as desired. WTRUs may read the beacon frame and obtain appropriate information for handing over to alternative systems having coverage areas that overlap that of the wireless local area network. The alternative systems may be any type of wireless system and the wireless local area network may be any type of wireless area network.

    Abstract: A WIRELESS NETWORK PROVIDES CONTROLLED WIRELESS COMMUNICATIONS WITH MULTI- MODE WIRELESS WTRUS. THE WIRELESS NETWORK HAS AT LEAST ONE BASE STATION (25) HAVING A TRANSCEIVER OPERATING IN AN INFRASTRUCTURE COMMUNICATION MODE WITH MULTI MODE WTRUS AND A CONTROLLER THAT TRANSMITS CONTROL SIGNALS VIA INFRASTRUCTURE COMMUNICATIONS WITH A WTRU THAT CONTROL PEER-TO-PEER MODE COMMUNICATIONS OF THAT WTRU WITH OTHER WTRUS. A WTRU HAS TRANSCEIVER COMPONENTS CONFIGURED FOR SELECTIVE OPERATION IN AN INFRASTRUCTURE COMMUNICATION MODE WITH A NETWORK BASE STATION AND IN A PEER-TO-PEER COMMUNICATION MODE WITH OTHER WTRUS. THE WTRU ALSO HAS A TRANSCEIVER CONTROLLER CONFIGURED TO SELECTIVELY CONTROL PEER-TO-PEER MODE COMMUNICATIONS WITH OTHER WTRUS BASED ON COMMUNICATION SIGNALS RECEIVED IN INFRASTRUCTURE COMMUNICATIONS WITH A NETWORK BASE STATION (25). PREFERABLY, THE TRANSCEIVER CONTROLLER IS CONFIGURED TO CONTROL THE TRANSCEIVER COMPONENTS TO SWITCH BETWEEN INFRASTRUCTURE COMMUNICATION MODE AND PEER-TO-PEER COMMUNICATION MODE BASED ON QUALITY OF SERVICE CRITERIA.(FIG 2)

    Abstract: A wireless network provides controlled wireless communications with multi-mode wireless WTRUs. The wireless network has at least one base station having a transceiver operating in an infrastructure communication mode with multi mode WTRUs and a controller that transmits control signals via infrastructure communications with a WTRU that control peer-to-peer mode communications of that WTRU with other WTRUs. A WTRU has transceiver components configured for selective operation in an infrastructure communication mode with a network base station and in a peer-to-peer communication mode with other WTRUs. The WTRU also has a transceiver controller configured to selectively control peer-to-peer mode communications with other WTRUs based on communication signals received in infrastructure communications with a network base station. Preferably, the transceiver controller is configured to control the transceiver components to switch between infrastructure communication mode and peer-to-peer communication mode based on Quality of Service criteria.
