Abstract: A wireless device is configured to automatically resign from an ad hoc ne twork. In some aspects the resignation may be based on automatic detection o f inactivity associated with the ad hoc network. For example, resignation fr om the ad hoc network may be based on absence of uplink and downlink traffic at a wireless device, absence of open sockets at a wireless device, or a la ck of beacon transmissions by other wireless devices. In the latter case, a lack of beacon transmissions by other wireless devices in the ad hoc network may be indicated by the transmission of a relatively large number of beacon s in succession by a wireless device.

Abstract: Techniques for selecting a radio interface for an application are described. A terminal identifies locally-addressable and globally-addressable wireless networks among wireless networks available to the terminal. Radio interfaces supported by the terminal may be prioritized based on the locally-addressable and globally-addressable wireless networks, information obtained for the application, the application type, etc. Different applications may have different radio interface preferences or requirements, which may be considered in prioritizing the radio interfaces. A suitable radio interface may be selected for the application based on the prioritized radio interfaces. WLAN interface may be selected for the application if (a) the WLAN interface is preferred and any WLAN is acceptable to the application or (b) a globally-addressable WLAN is available. A WLAN interface may be selected for the application if a globally-addressable WLAN is not available.

Abstract: Techniques for selecting a radio interface for an application are describ ed. A terminal identifies locally-addressable and globally-addressable wirel ess networks among wireless networks available to the terminal. Radio interf aces supported by the terminal may be prioritized based on the locally-addre ssable and globally-addressable wireless networks, information obtained for the application, the application type, etc. Different applications may have different radio interface preferences or requirements, which may be consider ed in prioritizing the radio interfaces. A suitable radio interface may be s elected for the application based on the prioritized radio interfaces. WLAN interface may be selected for the application if (a) the WLAN interface is p referred and any WLAN is acceptable to the application or (b) a globally-add ressable WLAN is available. A WWAN interface may be selected for the applica tion if a globally-addressable WLAN is not available.

Abstract translation: 无线设备被配置为从ad hoc网络自动退出。 在一些方面，辞职可以基于自动检测与ad hoc网络相关联的不活动性。 例如，从ad hoc网络的辞职可以基于无线设备处的上行链路和下行链路业务的缺失，无线设备处没有开放的套接字，或者缺少其他无线设备的信标传输。 在后一种情况下，自组织网络中其他无线设备缺少信标传输可通过无线设备连续传输相对大量的信标来指示。

Abstract: Techniques for performing WLAN system scanning and selection are described. A terminal performs multiple iterations of scan to detect for WLAN systems. A scan list containing at least one WLAN system to detect for is initially determined. For each scan iteration, a scan type may be selected from among the supported scan types. The selected scan type may indicate passive scan or active scan, frequency channels to scan, etc. A scan may be performed based on the selected scan type. Signal strength measurements are obtained for access points received during the scan and used to identify detected access points. After all scan iterations are completed, candidates access points are identified based on the scan results, e.g., based on the signal strength measurements for the detected access points and a detection threshold. The best candidate access point may be selected for association by the terminal.
