Claim of US Patent No. 10,117,216

1. A method implemented in a computing device, the method comprising:storing, in the computing device, mapping data that connect identifiers of cells in a grid reference system to regions that contain respective cells identified by the identifiers in the grid reference system;
receiving, in the computing device, coordinates of a mobile device;
receiving, in the computing device, an accuracy indicator of the coordinates of the mobile device; and
identifying, by computing device, a region in which the mobile device is located, by:
identifying, from the accuracy indicator and the coordinates of the mobile device, a plurality of locations, including a location specified by the coordinates of the mobile device and at least one location different from the location specified by the coordinates of the mobile device;
converting coordinates of the plurality of locations into respective cell identifiers in the grid reference system, wherein respective cells in the grid reference system identified by the respective cell identifiers contain respective coordinates from which the respective cell identifiers are converted;
determining, from the mapping data, one or more regions that are connected to the cell identifiers in the mapping data, including the region in which the mobile device is subsequently identified to be located; and
evaluating, based on a portion of the plurality of locations that is in the region, a confidence level that the mobile device is located in the region, wherein the mobile device is identified to be located within the region in response to a determination that the confidence level is above a threshold.
