SYSTEM AND METHOD FOR IN-BUILDING LOCATION DETERMINATION
First Claim
Patent Images
1. A method of determining a location of an electronic device when the electronic device is in a building, comprising:
- receiving location assistance information from a data source, wherein the location assistance information contains a position and a beacon identity for each of plural location beacons that are deployed in the building;
listening for one or more beacon identities from the location beacons; and
determining an area of the building in which the electronic device is located, the area determined from a distance parameter associated with each received beacon identity, each distance parameter indicating a relative distance between the electronic device and the position of the corresponding location beacon.

Abstract
To enhance in-building location determination of an electronic device, described is a system and a method that uses a blip access point to transfer location assistance information to the electronic device. The location assistance information may contain a map of dummy beacons that serve as reference points (e.g., landmarks) from which the electronic device may determine its location relative to the map information.

13. An electronic device, comprising:
-
a radio circuit over which location assistance information from a data source is received, wherein the location assistance information contains a position and a beacon identity for each of plural location beacons that are deployed in a building; and a control circuit that controls the electronic device to listen for one or more beacon identities from the location beacons and determine an area of the building in which the electronic device is located, the area determined from a distance parameter associated with each received beacon identity, each distance parameter indicating a relative distance between the electronic device and the position of the corresponding location beacon.

14. A location assistance system for aiding an electronic device to determine a location of the electronic device while in a building in which the location assistance system is deployed, comprising:
-
a plurality of location beacons that each broadcast a beacon identity; and a wireless access point that transmits location assistance information, wherein the location assistance information contains a position and the beacon identity for each of the plural location beacons. - View Dependent Claims (15, 16, 17, 18, 19, 20)
