    摘要: 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.

    摘要: A base station may be configured so that it operates in accordance with certain MAP transmission rules that may enable mobile stations to save battery power in certain situations. Upon receiving a MAP message, a mobile station may determine whether there is a burst allocated for the mobile station in the current frame by determining the value of at least one of the following: an idle users bit in the SUB-MAP pointer information element (IE), and a sleep users bit in the SUB-MAP pointer IE. The mobile station may discontinue processing of the MAP message and power down one or more components of the mobile station if there is not a burst allocated for the mobile station in the current frame.

    摘要: Certain embodiments provide techniques for background 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 processor, 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.

    摘要: 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.
