    Abstract: A GNSS enabled mobile device receives GNSS assistance data in a determined format from a central processing station communicatively coupled to a wide area reference network (WARN). The WARN comprises a first plurality of GNSS tracking stations from which usable signals are received by the central processing station, and a second plurality of GNSS tracking stations from which unusable or no signals are received by the central processing station. The central processing station generates the GNSS assistance data using a complete set of GNSS reference feeds of the WARN. The complete set of GNSS reference feeds comprises actual GNSS reference feeds from the first plurality of GNSS tracking stations and virtual GNSS reference feeds derived for the second plurality of GNSS tracking stations from processed actual GNSS reference feeds. The generated GNSS assistance data is reformatted into a determined format and is communicated to the GNSS enabled mobile device, accordingly.

    Abstract: A mobile device may determine its initial absolute location; may track using a plurality of sensors, its movements relative to the initial absolute location; and may generate location related data for a location based on that tracking. Tracking movement of the mobile device may comprise generating data corresponding to three-dimensional (3D) linear and/or rotational changes in position and/or location of the mobile device. The initial absolute location may be determined directly by the mobile device, based on GNSS signals and/or assisted GNSS (A-GNSS) data received from one or more location servers; and/or it may be estimated based on a location of a communication device that is communicatively coupled to the mobile device. The generated location related data may propagated by the mobile device to other mobile and/or communication devices, and/or to the location servers, where a reference database for supporting location related services (LBS) may be updated accordingly.

    Abstract: A wireless access point comprising a cellular receiver receives radio signals from a cellular base station. A cellular reference clock, synchronized to the cellular base station, is detected from the received radio signals. The detected cellular reference clock is utilized to stabilize a local access point clock for GNSS positioning. A clock difference between the local access point clock and the detected cellular reference clock is determined and the local access point clock may be adjusted accordingly. The adjusted local access point clock is utilized for clocking communications between the wireless access point and other communication devices. A time offset between the adjusted local access point clock and the detected cellular reference clock is provided to a remote location server. The remote location server retrieves time offset information from wireless access points served by the cellular base station so as to determine relative distances among the wireless access points.

    Abstract: A mobile device may be operable to receive historical location trail information of a building. A location of the mobile device within the building may be determined by placing, moving or snapping a reference location of the mobile device onto a trail according to the received historical location trail information. The historical location trail information may be acquired from a location server. The historical location trail information stored in the location server may be generated using a plurality of location samples that are provided by one or more other mobile devices that have been within the building. The historical location trail information may also be acquired from an indoor map of the building that is used by the mobile device for navigation within the building.

    Abstract: A multi-radio mobile device receives data transmission of a session from a serving access network in a heterogeneous network system comprising difference access networks. A handoff is performed based on the received data transmissions. User-level QoS for the wireless communication session is adjusted during the handoff based on connection QoS information in the current location of the multi-radio mobile device and/or a velocity of the multi-radio mobile device. Location-based network connection information, comprising call drop information and the connection QoS information, in the current location of the multi-radio mobile device is acquired from a location server. A target access network or a different base station in the serving access network associated with the highest connection QoS is selected. The user-level QoS is adjusted during the handoff for receiving the wireless communication session from the selected target access network or the different base station in the serving access network.

    Abstract: A GNSS enabled mobile device moves from a first area where GNSS signal quality and/or level is above a threshold to a second area where GNSS signal quality and/or level is below the threshold. The GNSS enabled mobile device in the second area determines its own location utilizing previous GNSS measurements in the first area. GNSS signals are received to calculate GNSS measurements whenever the GNSS enabled mobile device is in the first area. The calculated GNSS measurements are utilized to determine a location of the GNSS enabled mobile device within the first area. The GNSS enabled mobile device in the second area utilizes the most current GNSS measurements in the first area to determine its own location. Sensors such as an image sensor, a light sensor, an audio sensor and/or a location sensor are used to refine the location of the GNSS enabled mobile device in the second area.
