US 9,869,748 B2 · Locating a mobile device

Abstract

Identifying a location of a mobile device is disclosed (e.g., presuming user consent to the same). One or more received signal strengths (RSSs), comprising a first RSS, may be received by a first access point (AP) from the mobile device. The RSSs may be used to identify a grid area, comprising a first grid space. A signal distance between the first grid space and the first AP may be identified using the first RSS, and combined with a first grid space distance, comprising a known distance between the first grid space and the first AP, to determine a first grid space likelihood score for the first grid space. A second grid space likelihood score may be determined for a second grid space (e.g., and a third, etc.), and the grid space comprising a desired grid space likelihood score (e.g., highest) may be selected as the mobile device location.

Dependent claims

A computer based method for identifying a location of a mobile device as implemented by a processor on a mobile device, comprising:

receiving a query from an application resident on the mobile device to identify the location of the mobile device;
accessing a data store comprising a plurality of received signal strengths (RSS) from a plurality of access points (AP) previously received by the mobile device;
retrieving data from the data store based on the query;
identifying a candidate area and creating grid data for a plurality of grid spaces in the identified candidate area according to the retrieved data from the data store;
determining a grid space likelihood score for each of the plurality of grid spaces based on the grid data and the query;
and
identifying the location of the mobile device based on the determined grid space likelihood scores.
