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 when the electronic device enters the building, wherein the location assistance information is a logistical map containing 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;
collecting data in addition to the location assistance information as the electronic device moves within the building;
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 and from the collected data, each distance parameter indicating a relative distance between the electronic device and the position of the corresponding location beacon contained in the location assistance information; and
transmitting the collected data from the electronic device to a location assistance system when the electronic device departs the building, the transmitted collected data for updating the location assistance information for making future location determinations for the electronic device or another electronic device.

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 when the electronic device enters the building, wherein the location assistance information is a logistical map containing 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; collect data in addition to the location assistance information as the electronic device moves within the building; 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 and from the collected data, each distance parameter indicating a relative distance between the electronic device and the position of the corresponding location beacon contained in the location assistance information; and transmit the collected data from the electronic device to a location assistance system when the electronic device departs the building, the collected data for updating the location assistance information for making future location determinations for the electronic device or another electronic device. - View Dependent Claims (14)

15. 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 when the electronic device enters the building, wherein the location assistance information is a logistical map containing a position and the beacon identity for each of the plural location beacons, wherein the location assistance system is configured to; receive data collected by the electronic device when the electronic device departs the building; and update the location assistance information using the collected data, the updated location assistance information for making future location determinations for the electronic device or another electronic device. - View Dependent Claims (16, 17, 18, 19, 20)
