    摘要： Devices and methods are provided for providing self-timing and self-locating in an access point (AP) base station. In one embodiment, the method involves receiving Satellite Positioning System (SPS) signals from a first data source (e.g., plurality of satellites), wherein the SPS signals may include SPS time data, SPS frequency data, and SPS position data. The method may further involve obtaining from a second data source (e.g., cell site, terrestrial navigation station, server, user input interface, etc.) at least one of second time data, second frequency data and second position data, and determining relative reliability of the first and second data sources.

    摘要： A method includes receiving a command corresponding to a user input at a user interface of a mobile device. The method includes comparing the received command to a predetermined set of commands associated with determining a location of the mobile device. The method further includes initiating a wireless data signal scan (e.g., prior to receiving an explicit request from Base Station or PDE) to generate a list that identifies wireless data (e.g., non-global positioning system (non-GPS)) signals that are detectable by the mobile device in response to determining that the received command corresponds to at least one command of the predetermined set of commands.

    摘要： In a radio frequency (RF) receiver, a receiver RF chain is tuned to a first (e.g., global positioning system (GPS)) channel to permit receipt of a first (e.g., GPS) signal over the first (e.g., GPS) channel on the receiver RF chain during a first time duration. The receiver RF chain is tuned to a second (e.g., cellular page) channel to permit receipt of a second (e.g., cellular page) signal over the second (e.g., cellular page) channel on the receiver RF chain during a second time duration, following the first time duration. The first (e.g., GPS) signal is processed during the first time duration and the second time duration, without any apparent interruption of the first (e.g., GPS) signal during the second time duration. The processing, for example, provides a bridge signal (e.g., an estimated GPS signal on the receiver RF chain) during the second time duration.
