摘要： A system for the collection, aggregation and analysis of location based crowd sourcing data includes a server that controls the distribution of crowd sourcing requests and workloads to a plurality of external mobile platforms. The server receives crowd sourcing queries from multiple parties and provides measurement requests to the mobile platforms, e.g., based on the location of the mobile platforms. Upon receipt of the measured contextual data from the mobile platforms, the server distributes information, such as the raw measured contextual data or an analysis of the measured contextual data, to the appropriate requesting parties in a secure manner. The mobile platform may receive a plurality of measurement requests from a remote server based on crowd sourcing queries from a plurality of parties. The mobile platform may measure and provide to the remote server contextual data in response to the plurality of measurement requests.

摘要： One method for wirelessly determining a position of a mobile station includes measuring a round trip time (RTT) to a plurality of wireless access points, estimating a first distance to each wireless access point based upon the round trip time delay and an initial processing time associated with each wireless access point, estimating a second distance to each wireless access point based upon supplemental information, combining the first and second distance estimates to each wireless access point, and calculating the position based upon the combined distance estimates. Another method includes measuring a distance to each wireless access point based upon a wireless signal model, calculating a position of the mobile station based upon the measured distance, determining a computed distance to each wireless access point based upon the calculated position of the mobile station, updating the wireless signal model, and determining whether the wireless signal model has converged.

摘要： Various methods, apparatuses and/or articles of manufacture are provided which may be implemented to support mobile device positioning through the use of adaptive passive scanning and/or adaptive active probing techniques. For example, a mobile device may acquire signals from wireless transceivers, identify wireless transceivers based, at least in part, on the acquired signal(s), determine a received signal strength measurement for each of the wireless transceivers based, at least in part, on the acquired signal(s), and determine a transmission power of a probe signal to be transmitted to at least one of the wireless transceivers based, at least in part, on at least one of the received signal strength measurements.

The method also includes determining an expected processing delay of the wireless access point, analyzing the measured round trip time delay and the expected processing delay, and validating the wireless access point based upon the analysis. An apparatus includes a wireless transceiver, a processing unit coupled to the wireless transceiver, and a memory coupled to the processing unit. The processing unit is configured to identify a target wireless access point for validation, measure a round trip time delay to the wireless access point, determine an expected processing delay of the wireless access point, analyze the measured round trip time delay and the expected processing delay, and validate the wireless access point based upon the analysis.
