Abstract: Methods, apparatus, and computer program products for determining a mobile device location. An example of a method for determining a mobile device location includes receiving signals from a transmitter, measuring signal characteristics of the received signals, and downloading data from a database corresponding to a defined region associated with the transmitters. The downloaded data includes a set of position points, a classification of each position point, and expected signal characteristics for each position point. The method further includes comparing the measured signal characteristics with the expected signal characteristics for each position point, assigning a weight to position points based on the compared signal characteristics, and determining the mobile device location by selecting one position point from the set as a position point solution corresponding to the mobile device location based on the assigned weight. The position point solution is constrained by the classification of each position point.

Abstract: Systems, apparatus and methods disclosed herein facilitate mobile station (MS) location determination using MS captured images of known points of interest (POIs). In some embodiments, each POI is associated with a corresponding visibility map comprising a set of grid points, and a subset of the POIs may be identified from the MS captured images by matching the MS captured images of each POI in the subset with corresponding stored images. A cumulative grid point weight for a plurality of grid points in the visibility maps associated with the POIs in the subset may be computed. The cumulative grid point weight for each grid point represents the probability that the MS is located at that grid point. The location of the MS may be estimated based on the cumulative grid point weights of the plurality of grid points.

Abstract: An embodiment is directed to generating a polygon representation of a plurality of points of interest (POIs) in a scene having a corresponding base level map of the scene, and creating a new level map including a reduced number of polygon representations of POIs on the basis of elimination of POIs having a lower than specified POI importance level. In another embodiment, a mobile device (e.g., the user device) can specify the specified POI importance level to trigger the generation and delivery of the new level map which conforms to the specified POI importance level so that the new level map can be displayed to a user of the mobile device (e.g., in conjunction with navigation instructions to one or more of the remaining POIs).
