Abstract: Systems, apparatus and methods to perform hypothesis localization are presented. An access point (AP) is associated with one specific area, such as an LCI (location context identifier). Each specific area defines area information comprising an identifier, a list of APs, and a map of the specific area. Each specific area, and associated APs from the list of APs, is hypothesized as the specific area containing a mobile device. For each hypothesized area, a mobile device trajectory is formed using just listed APs from that area, to form a plurality of mobile device trajectories. After evaluating the resulting plurality of mobile device trajectories, a selection is made of the best fitting mobile device trajectory.

Abstract: Systems, apparatus and methods for determining a location of a mobile device are presented. Often a mobile device requests assistance data from a location server. If the mobile device expects a significant delayed response in receiving the assistance data, the mobile device may determine a seed location or rough location estimate from a server. The mobile device may also request a map to display and/or a data structure for its estimator. The mobile device may preload the estimator with the rough location estimate and/or the data structure. After preloading, the estimator determines a location of the mobile device. Also, the mobile device may show the map to a user via a display.

In an example, a method for processing positioning data associated with one or more access points includes choosing, for inclusion in the positioning data, one or both of: (1) ranging model parameters to enable a mobile device to compute first heatmap data for multiple points in a ranging region of a heatmap, or (2) second heatmap data for a plurality of points in a non-ranging region of the heatmap. The method can also include transmitting the positioning data, such as to a mobile device. The positioning data can also include both the ranging model parameters and the second heatmap data when the ranging region and the non-ranging region fully or partially overlap, in which case the second heatmap data provides correction data to enable the mobile device to modify the computed heatmap data in the area where the two regions overlap.
