Abstract

A location estimation method and a communication device configured to estimate location and automatically connect to one or more wireless display devices based on the determined location. The estimation of location can be based on one or more location signatures that include information of the wireless display device(s). The location estimation method can include identifying available access points (APs) and wireless display adapters, determining wireless characteristics of the available APs and wireless display adapters, calculating match scores based on the wireless characteristics of the available APs and the wireless characteristics of the available wireless display adapters, determining a location signature based on the determined match scores, and determining a location based on the location signature. The communication device can be configured to automatically connect to the wireless display device(s). The communication device can operate in a standby display mode upon the connection.

First claim

What is claimed is:

1. A location estimation method to assist a communication device to establish a wireless display connection, comprising:
identifying, by the communication device, one or more available access points (APs) and one or more available wireless display adapters;
determining, by the communication device, one or more wireless characteristics of the one or more available APs and one or more wireless characteristics of the one or more available wireless display adapters;
calculating, by the communication device, one or more match scores based on the one or more wireless characteristics of the one or more available APs and the one or more wireless characteristics of the one or more available wireless display adapters;
identifying, by the communication device, a location signature based on the one or more match scores; and
identifying, by the communication device, a location of the communication device based on the location signature.

2. The location estimation method of claim 1 , wherein the one or more wireless characteristics of the one or more available APs and the one or more wireless characteristics of the one or more available wireless display adapters comprise received signal strength indication (RSSI) values of the available APs and the available wireless display adapters, respectively.

3. The location estimation method of claim 1 , further comprising:
calculating one or more AP location error values based on the one or more wireless characteristics of the corresponding one or more available APs; and
calculating one or more AP location scores for the one or more available APs based on the corresponding one or more AP location error values.

4. The location estimation method of claim 3 , further comprising:
calculating one or more adapter location error values based on the one or more wireless characteristics of the corresponding one or more available wireless display adapters; and
calculating one or more adapter location scores for the one or more available wireless display adapters based on the corresponding one or more adapter location error values.

5. The location estimation of claim 4 , wherein calculating the one or more match scores is based on the one or more adapter location scores and the one or more AP location scores.

6. The location estimation method of claim 5 , further comprising:
ranking a plurality of location signatures based on the one or more match scores, the plurality of location signatures comprising the location signature.

7. The location estimation method of claim 6 , wherein determining the location signature is further based on the ranking of the plurality of location signatures.

8. The location estimation method of claim 1 , further comprising:
automatically connecting, by the communication device, to a wireless display adapter of the one or more available wireless display adapters based on the location signature.

9. The location estimation method of claim 8 , wherein the location signature identifies the wireless display adapter.

10. The location estimation method of claim 8 , wherein automatically connecting to the wireless display adapter comprises initiating the connection to the wireless display adapter in a standby display mode.

11. A communication device operable to establish a wireless display connection, comprising:
a transceiver configured to communicate with one or more access points (APs) and one or more wireless display adapters; and
a controller configured to:
identify available APs of the one or more APs and available wireless display adapters of the one or more wireless display adapters;
identify one or more wireless characteristics of the available APs and one or more wireless characteristics of the available wireless display adapters;
calculate one or more match scores based on the one or more wireless characteristics of the available APs and the one or more wireless characteristics of the available wireless display adapters;
identify a location signature based on the one or more match scores; and
identify a location of the communication device based on the location signature.

12. The communication device of claim 11 , wherein the one or more wireless characteristics of the available APs and the one or more wireless characteristics of the available wireless display adapters comprise received signal strength indication (RSSI) values of the available APs and available wireless display adapters, respectively.

13. The communication device of claim 11 , wherein the controller is further configured to:
calculate one or more AP location error values based on the one or more wireless characteristics of the corresponding available APs; and
calculate one or more AP location scores for the available APs based on the corresponding one or more AP location error values.

14. The communication device of claim 13 , wherein the controller is further configured to:
calculate one or more adapter location error values based on the one or more wireless characteristics of the corresponding available wireless display adapters; and
calculate one or more adapter location scores for the available wireless display adapters based on the corresponding one or more adapter location error values.

15. The communication device of claim 14 , wherein calculating the one or more match scores is based on the one or more adapter location scores and the one or more AP location scores.

16. The communication device of claim 15 , wherein the controller is further configured to:
rank a plurality of location signatures based on the one or more match scores, the plurality of location signatures comprising the location signature.

17. The communication device of claim 16 , wherein identifying the location signature is further based on the ranking of the plurality of location signatures.

18. The communication device of claim 11 , wherein the controller is further configured to:
automatically connect to a wireless display adapter of the available wireless display adapters based on the location signature.

19. The communication device of claim 18 , wherein the location signature identifies the wireless display adapter.

20. The communication device of claim 19 , wherein automatically connecting to the wireless display adapter comprises initiating the connection to the wireless display adapter in a standby display mode.

21. A communication device operable to establish a wireless display connection, comprising:
a transceiving means for communicating with one or more access points (APs) and one or more wireless display adapters; and
a controlling means for:
identifying available APs of the one or more APs and available wireless display adapters of the one or more wireless display adapters;
identifying one or more wireless characteristics of the available APs and one or more wireless characteristics of the wireless display adapters;
calculating one or more match scores based on the one or more wireless characteristics of the available APs and the one or more wireless characteristics of the available wireless display adapters;
identifying a location signature based on the one or more match scores; and
identifying a location of the communication device based on the location signature.

22. The communication device of claim 21 , wherein the controlling means is further configured for:
automatically connecting to a wireless display adapter of the available wireless display adapters based on the location signature.
