    Abstract: A wireless network provides controlled wireless communications with multi-mode wireless WTRUs (33, 37). The wireless network has at least one base station (25) having a transceiver operating in an infrastructure communication mode withmulti mode WTRUs and a controller that transmits control signals via infrastructure communications with a WTRU that control peer-to-peer mode communications (40) 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(duality of Service criteria).

    Abstract translation: 无线网络提供与多模式无线WTRU的受控无线通信（33,37）。 所述无线网络具有至少一个基站（25），所述基站具有以与多模WTRU的基础设施通信模式操作的收发机，以及控制器，所述控制器经由与WTRU的基础设施通信来传输控制信号，所述WTRU控制对等模式通信（40） 该WTRU与其他WTRU。 WTRU具有被配置用于在与网络基站的基础设施通信模式中进行选择性操作并且处于与其他WTRU的对等通信模式中的收发器组件。 WTRU还具有收发器控制器，该收发器控制器被配置为基于在与网络基站的基础设施通信中接收到的通信信号来选择性地控制与其他WTRU的对等模式通信。 优选地，收发器控制器被配置为基于（服务标准的二重性）来控制收发器组件以在基础设施通信模式和对等通信模式之间切换。

    Abstract: A system facilitates handover of a wireless transmit and receive unit (WTRU) between a cellular network and a wireless local area network (WLAN). The WLAN communicates with a cellular network. A location of the WTRU is determined. The coverage areas of the WLAN and cellular network are determined. The WTRU is informed of the existence of the WLAN when the WTRU approaches the coverage area of the WLAN. The WTRU is handed over from the cellular network to the WLAN when the WTRU is in the coverage area of the WLAN and vice versa.

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.
