摘要： Techniques for supporting positioning with differential corrections are described. In an aspect, differential correction for a satellite may include (i) a user differential range error (UDRE) indicating an uncertainty in a pseudo-range correction for the satellite, (ii) a UDRE growth rate, which may be a scaling factor for the UDRE, and (iii) a time of validity for UDRE growth rate, which may be a time unit used to apply the scaling factor. In one design, a terminal may send a request message to ask for differential correction information and may receive a response message. The terminal may obtain differential correction ( e.g. , a UDRE, a UDRE growth rate, and a time of validity for UDRE growth rate) for each of at least one satellite from the response message. The terminal may derive a location estimate for itself based on the differential correction for each satellite.

摘要： A mobile Communications device uses a method for determining position that involves a positioning filter, such as a Kalman filter, which is initialized with measurements from reference stations such as satellite vehicles and/or base stations which may be acquired during different epochs. Accordingly, the positioning filter may be used for position estimation without the need to first acquire at least three different signals during the same measurement epoch.

摘要： A mobile device may use one or more outlier detectors to detect likelihoods that an outlier condition exists for a satellite positioning system (SPS) position fix. In some implementations, an outlier detector may compare a computed position fix to an element of assistance data to generate an outlier likelihood. A decision to perform a recovery operation may be made based, at least in part, on a generated outlier likelihood. In some implementations, a computed reliability of the position fix may also be considered in making a recovery decision.

摘要： Techniques for supporting location services in a user plane location architecture such as Secure User Plane Location (SUPL) are described. In an aspect, a terminal informs a location server of service capabilities of the terminal. The location server uses the service capabilities to request only location services supported by the terminal and to avoid requesting unsupported location services. The terminal generates a message containing its service capabilities and sends the message via a user plane, e.g., SUPL. The location server receives the message, obtains the service capabilities of the terminal, and stores these service capabilities for future network-initiated location sessions with the terminal. The location server determines whether a location service is supported by the terminal based on the service capabilities of the terminal. The location server communicates with the terminal via the user plane for the location service if supported by the terminal.

摘要： Navigation assistance information for a mobile station is acquired based on a feature descriptor of an image of a visual beacon captured by the mobile station. The navigation assistance information includes locations of neighboring visual beacons, locations of wireless positioning resources; user environmental context information. The navigation assistance information may then be used to assist in navigating within the local environment. The visual beacon may be an artificial feature, such as a QR code or other type of matrix or bar code or a natural feature, such as a statute or architectural detail. The mobile station may request navigation assistance by transmitting the feature descriptor to a server. The server retrieves the navigation assistance information from a database based on the feature descriptor and optionally location information, which may also be provided in the navigation assistance request, and transmits the navigation assistance information to the mobile station.

摘要： A multipath detector includes an RF module receiving multiple signals, and a correlator module receiving the signals from the RF module. The correlator module correlates the signals to create a composite ACF, and produces samples of the composite autocorrelation function (ACF). The samples are time delayed relative to each other. The multipath detector also includes a carrier phase processor that receives the samples and estimates carrier phases associated with each of the samples. The carrier phase processor employs the estimated carrier phases to determine if one of the signals is subject to a multipath delay.
