Abstract

Embodiments allow a station to determine its location and report the location to a access point or other network entity. The station obtains agreement with an access point, group of access points, or other network entity to provide its location to a designated accuracy level and the access point(s) agree to provide services such as access to a location service, the access point(s) location to a designated positional accuracy, etc. The station measures its position and induces an error in its reported location. The induced error prevents an exact location of the station from being determined by the access point(s) or others, thus preserving the privacy of the station. The location reported by the station may be absolute (e.g., geographic coordinates) or relative to a landmark, location, etc.

Claims

1. An apparatus of a wireless device comprising:

memory and processing circuitry configured to perform multiple phases to report a location of the wireless device to a second wireless device, the multiple phases comprising;

an accuracy agreement and negotiation phase comprising;

access of a location determination policy received from the second wireless device, the policy comprising a device positional accuracy level that a device is to provide on its location as part of an agreement;

a measurement phase comprising;

identification of an actual device location to a given level of accuracy;

derivation of a reported device location, the reported device location comprising the actual device location with an induced error, the reported device location to comply with the positional accuracy level; and

a reporting phase comprising;

cause the reported device location to be sent to the second wireless device.

2. The apparatus of claim 1 wherein the second wireless device is an access point and where the location determination policy further comprises an access point positional accuracy that the access point will comply with in reporting its location.

3. The apparatus of claim 1 wherein the accuracy agreement and negotiation phase occurs between a plurality of access points, and wherein the accuracy agreement and negotiation phase further identifies an access positional accuracy for each of the plurality of access points.

4. The apparatus of claim 1 wherein the accuracy agreement and negotiation phase further comprises:

access of a second location determination policy received from the second wireless device, each of the first and second location determination policies specifying a different device positional accuracy level and each of the first and second location determination policies comprising additional terms that specify at least one service that the second wireless device will provide if the wireless device selects the associated policy;

selection of either the first location determination policy or the second determination policy based on a set of criteria;

cause an indication of which policy has been selected to be sent to the second wireless device.

5. The apparatus of claim 4 wherein the set of criteria comprises at least one of:

an agreement by the wireless device to allow advertising to be placed on the wireless device;

a cost of service provided by the second wireless device to the wireless device;

a level of service provided by the second wireless device to the wireless device;

a trust level of the second wireless device to the wireless device;

a trust level of the wireless device to the second wireless device; and

the additional terms associated with a particular policy.

6. The apparatus of claim 4 wherein the additional terms for the first location determination policy and the second location determination policy further comprise at least one of:

a positional accuracy level that the second wireless device will provide to the wireless device;

a cost of the additional service; and

a level of service to be provided.

7. The apparatus of claim 1 wherein the processing circuitry is further configured to perform multiple rounds of the measurement phase and the reporting phase without repeating the accuracy agreement and negotiation phase.

8. The apparatus of claim 1 further comprising transceiver circuitry coupled to the processing circuitry and wherein the processing circuitry causes the transceiver circuitry to send information to and receive information from the second wireless device.

9. The apparatus of claim 8 further comprising at least one antenna coupled to the transceiver circuitry.

10. A method executed by a wireless device comprising:

performing an accuracy agreement and negotiation phase comprising;

receiving from a second wireless device a location determination policy comprising a device positional accuracy level that the wireless device will be required to provide on its location as part of an agreement;

performing a measurement phase comprising;

identifying, by the wireless device, an actual device location to a given level of accuracy;

deriving a reported device location, the reported device location comprising the actual device location with an induced error, the reported device location complying with the positional accuracy level; and

performing a reporting phase comprising;

sending to the second wireless device the reported device location.

11. The method of claim 10 wherein the second wireless device is an access point and where the location determination policy further comprises an access point positional accuracy that the access point will comply with in reporting its location.

12. The method of claim 10 wherein the accuracy agreement and negotiation phase occurs between a plurality of access points, and wherein the accuracy agreement and negotiation phase further identifies an access positional accuracy for each of the plurality of access points.

13. The method of claim 10 wherein the accuracy agreement and negotiation phase further comprises:

receiving from the second wireless device a second location determination policy, each the first and second location determination policies specifying a different device positional accuracy level and each of the first and second location determination policies comprising additional terms that specify at least one service that the second device will provide if the device selects the associated policy;
