    Abstract: Certain embodiments provide techniques for back-ground scanning in a wireless communication device receiving signals from multiple base stations using a background scanning processor separate from a receive processor. The techniques generally include buffering raw signal data from multiple base stations, forwarding the raw signal data to a receive baseband processor for decoding data from a first one of the base stations that is currently designated as a serving base station with an active connection to the wireless communications device, forwarding the raw signal data to a background scanning pro-cessor, separate from the receive baseband processor, and generating channel characteristics corresponding to the multiple base stations with the background scanning processor without interrupting the exchange of data with the first base station designated as the serving base station.

    Abstract: Certain embodiments allow security keys to be maintained across mobile device states, or communication events, such as hand-over, and system idle and sleep power savings modes. By monitoring the lifetime of security keys, keys may be refreshed in an effort to ensure key lifetimes will not expire during a hand-over process or other device unavailable state.

    Abstract translation: 某些实施例允许跨越移动设备状态或通信事件（例如切换，以及系统空闲和睡眠功率节省模式）来维护安全密钥。 通过监视安全密钥的生命周期，可以刷新密钥以努力确保密钥生命期在切换过程或其他设备不可用状态期间不会过期。

    Abstract: Techniques presented herein allow a wireless device, (e.g., a mobile station, MS) to automatically enter a low power state when detecting silence based on monitored VoIP transmissions. Automatically entering the low power state may help the wireless device conserve power. In addition, for certain types of scheduling services in which bandwidth is allocated to the wireless device from within a system (e.g., Unsolicited Grant Service or extended real time polling service), automatically entering the low power state when silence is detected may also free up bandwidth (i.e., that would have otherwise been allocated to the wireless device entering the low power state) for allocation to other wireless devices in the system.

    Abstract translation: 本文中提供的技术允许无线设备（例如，移动站，MS）在基于监视的VoIP传输检测静音时自动进入低功率状态。 自动进入低功耗状态可能有助于无线设备节省电力。 此外，对于某些类型的调度服务，其中系统内的带宽被分配给无线设备（例如，非请求授权服务或扩展实时轮询服务），当检测到静音时自动进入低功率状态也可以释放 带宽（即否则将分配给进入低功率状态的无线设备）用于分配给系统中的其他无线设备。
