The subject matter disclosed herein relates to determining a background location of a mobile device using one or more signal metrics.

On demand positioning

Methods and apparatuses for position determination and other operations. In one embodiment of the present invention, a mobile station uses wireless signals from a plurality of wireless networks (e.g., with different air interfaces and/or operated by different service providers) for position determination (e.g., for data communication, for obtaining time and/or frequency information, for range measurement, for sector or altitude estimation). In one embodiment of the present invention, mobile stations are used to harvest statistical data about wireless access points (e.g., the locations of mobile stations that have received signals from the wireless access points, such as from cellular base stations, wireless local area network access points, repeaters for positioning signals, or other wireless communication transmitters) and to derive location information (e.g., position and coverage area of the wireless access points) for the wireless networks from the collected statistical data.

Method and apparatus for wireless network hybrid positioning

Methods and apparatuses are provided for use with mode switchable navigation radios and the like. The methods and apparatuses may be implemented to selectively switch between certain operating modes based, at least in part, one or more determinations relating to one or more satellite positioning signals and/or space vehicles.

Methods and apparatuses for use with mode-switchable navigation

The subject matter disclosed herein relates to positioning systems and location determination using measurement stitching.

Position determination using measurements from past and present epochs

An application executed within a mobile station to be triggered only by a network element, such as a mobile positioning center (MPC) or a Mobile Center (MC). The network element is coupled to a base station. The network element is responsible for authorizing an application that is either resident within the mobile station or that is run in a device that is resident elsewhere in the network. The mobile station communicates with the network element over a communication session through the base station and other infrastructure components. The mobile station initiates a mobile originated positioning session over a second communication session with a positioning assistance server.

Location based service (LBS) system, method and apparatus for triggering of mobile station LBS applications

Methods and apparatuses for position determination and other operations. In one embodiment of the present invention, a mobile station uses wireless signals from a plurality of wireless networks (e.g., with different air interfaces and/or operated by different service providers) for position determination (e.g., for data communication, for obtaining time and/or frequency information, for range measurement, for sector or altitude estimation). In one embodiment of the present invention, mobile stations are used to harvest statistical data about wireless access points (e.g., the locations of mobile stations that have received signals from the wireless access points, such as from cellular base stations, wireless local area network access points, repeaters for positioning signals or other wireless communication transmitters) and to derive location information (e.g., position and coverage area of the wireless access points) for the wireless networks from the collected statistical data.

Wireless network hybrid positioning

Techniques for determining the position of a mobile device using almanac data are provided as are techniques for providing almanac data to the mobile device from a location server. The almanac data can be provided to the mobile device based on coarse location information provided by the mobile device. The almanac data can include information Media Access Control (MAC) addresses of one or more wireless access points and most recently used channel identification. The almanac data can also be binned by location by the location server and a subset of the almanac data can be selected to be provided to the mobile device based on the coarse location of the mobile device and on positioning effectiveness criteria associated with the wireless access points included in the almanac data.

Techniques for reducing scans for indoor position determination

Described are devices, methods, techniques and systems for locating a portable services access transceiver (PSAT) for use in aiding emergency '911' services. In one implementation, one or more conditions indicative of movement of a PSAT may initiate a process for obtaining a new estimated location of the PSAT. In another implementation, a location of a PSAT may be determined or updated using indoor navigation techniques.

System and/or method of locating a portable service access transceiver

Spoofing of a satellite positioning system is detected by receiving position location data from multiple sources. The received data is compared and inconsistent data is marked. A position location is estimated based on the received position location data, while accounting for the marked inconsistent data.

Anti-spoofing detection system

Location-independent approaches are provided for determining, using a mobile device, whether a wireless transmitter has been moved to a new location. An example method includes obtaining at least a portion of a reference radio frequency (RF) signature database; measuring signals from a plurality of wireless transmitters proximate to the mobile device; identifying a candidate wireless transmitter; deriving an observed radio frequency (RF) signature for the candidate wireless transmitter from signals from at least one wireless transmitter of the plurality of wireless transmitters other than the candidate wireless transmitter; determining whether the candidate wireless transmitter has been moved to a new location by comparing the observed RF signature for the candidate wireless transmitter to a reference RF signature associated with the candidate wireless transmitter; and generating an indicator that the candidate wireless transmitter has been moved responsive to the candidate wireless transmitter having been moved.

Use of RF signatures to detect moved wireless transmitters

An apparatus and method are disclosed for achieving receiver diversity. A wireless unit includes a plurality of antennas, an antenna selector to select one or more antennas from the plurality of antennas, a processor with input data from an inertial sensor for monitoring the orientation of the wireless unit. Based on the input data, the processor commands the antenna selector to select one or more antennas. In one aspect, the processor is a diversity processor. Based on the input data from the inertial sensor, the diversity processor computes the combination of the received signals. In another aspect, the wireless unit further includes a baseband processor to process the output of the diversity processor for a particular unit application.
