摘要： Methods and apparatus for ranging with one or more neighboring sectors during normal operation of a mobile station (MS) with its serving sector are provided. The ranging results may be frequently updated in an effort to accelerate the handover process to another base station (BS) providing coverage for one of the neighboring sectors.

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： 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.

摘要： A method for frame number synchronization in a wireless communication network may be implemented by a base station. The method may include determining a current time from a timing source that is common to multiple other base stations. The method may also include determining a time offset between the current time and a reference time, wherein the base station and the multiple other base stations use the same reference time for determining the time offset. The method may also include determining a current frame number based on the time offset.

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.
