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 avoiding collision of traffic in a wireless network are described. A station detects for synchronization of its traffic with traffic of other stations. The station may detect for synchronization based on, e.g., percentage of first transmission failures, counters indicative of statistics of transmitted frames, and/or other information. The station may confirm synchronization of its traffic, e.g., by monitoring for traffic from another station during a service period for the station. The station adjusts transmission of its traffic when synchronization is detected to avoid collision with the traffic of the other stations. The station may delay transmission of its traffic by a predetermined amount of time, by a pseudo-random amount, or until after the other stations finish their transmissions.

Abstract translation: 描述了避免无线网络中业务冲突的技术。 站点检测其流量与其他站点的流量同步。 基站可以基于例如第一传输故障的百分比，指示传输帧的统计数据的计数器和/或其他信息来检测同步。 该站可以确认其业务的同步，例如通过在该站的服务周期期间监视来自另一个站的业务。 当检测到同步时，该站调整其业务的传输，以避免与其他站的业务相冲突。 站可以将其业务的传输延迟预定量的时间，伪随机量，或者直到其他站完成其传输。
