Abstract

The present invention provides systems and methods for self-labeling access points with their geographic location from received beacon frames. In particular, the present invention transmits beacon frames including temporary location information from mobile devices. The beacon frames are received by an access point, filtered by the access point and then used to determine a location. Once the location has been determined, the access point uses the determined location to self-label itself by converting the location information to a geographic code and inserting it as part of the SSID of the access point'"'"'s beacon signal. The present invention also includes a number of methods using geographic codes including a method for generating and transmitting geographic codes for mobile devices, a method for determining a location of an access point, a method for self-labeling an access point, and a method for filtering beacon frames.

Claims

1. A method for generating a geographic code, the method comprising:

retrieving and displaying a map to a user;

receiving input from the user;

generating a geographic code based on the input from the user;

inserting the geographic code in an SSID of a beacon of an access point;

monitoring the access point for movement;

determining whether the access point has moved; and

in response to determining that the access point has moved, deactivating the geographic code by removing the geographic code from the SSID of the beacon of the access point.

2. The method of claim 1, wherein retrieving and displaying the map to the user is part of setting up the access point.

3. The method of claim 1, wherein generating the geographic code based on the input from the user includes encoding a latitude and a longitude of the access point into a defined number of characters.

4. The method of claim 1, wherein in response to determining that the access point has moved:

re-computing a geographic code; and

inserting the re-computed geographic code in the SSID of the beacon of the access point.

5. The method of claim 1, further comprising:

retrieving a request for the geographic code;

displaying a graphical user interface;

wherein retrieving and displaying the map to the user comprises displaying the map in the user interface;

wherein receiving input from the user includes receiving an address;

converting the address to coordinates for a location;

wherein generating the geographic code based on the input from the user includes creating the geographic code from the coordinates for the location; and

outputting the geographic code.

6. The method of claim 5, wherein the geographic code is output by displaying, in the graphical user interface, the geographic code in a comment box and an input address mark on the map near the location.

7. A system comprising:

a graphical user interface configured to display a map to a user;

an input device configured to receive input from the user;

one or more processors configured to;

generate a geographic code based on the input from the user;

insert the geographic code in an SSID of a beacon of an access point;

monitor the access point for movement;

determine whether the access point has moved; and

in response to determining that the access point has moved, deactivate the geographic code by removing the geographic code from the SSID of the beacon of the access point.

8. The system of claim 7, wherein displaying the map to the user is part of setting up the access point.

9. The system of claim 7, wherein the one or more processors are configured to generate the geographic code based on the input from the user by encoding a latitude and a longitude of the access point into a defined number of characters.

10. The system of claim 7, wherein, in response to determining that the access point has moved, the one or more processors are configured to:

re-compute a geographic code; and

insert the re-computed geographic code in the SSID of the beacon of the access point.

11. The system of claim 7, wherein the one or more processors are configured to:

retrieve a request for the geographic code;

receive input from the user including an address via the input device;

convert the address to coordinates for a location;

generate the geographic code using the coordinates for the location; and

output the geographic code.

12. The system of claim 11, wherein the graphical user interface is configured to display the geographic code in a comment box and an input address mark on the map near the location.

13. A computer program product comprising a non-transitory computer useable medium including a computer-readable program, wherein the computer-readable program when executed on a computer causes the computer to:

retrieve and display a map to a user;

receive input from the user;

generate a geographic code based on the input from the user;

insert the geographic code in an SSID of a beacon of an access point;

monitor the access point for movement;

determine whether the access point has moved; and

in response to determining that the access point has moved, deactivate the geographic code by removing the geographic code from the SSID of the beacon of the access point.

14. The computer program product of claim 13, wherein retrieving and displaying the map to the user is part of setting up the access point.

15. The computer program product of claim 13, wherein the instructions cause the computer to generate the geographic code based on the input from the user by encoding a latitude and a longitude of the access point into a defined number of characters.

16. The computer program product of claim 13, wherein in response to determining that the access point has moved, the instructions cause the computer to:

re-compute a geographic code; and

insert the re-computed geographic code in the SSID of the beacon of the access point.

17. The computer program product of claim 13, wherein the instructions cause the computer to:

retrieve a request for the geographic code;

display a graphical user interface including the map;

receive input from the user including an address;

convert the address to coordinates for a location;

generate the geographic code using the coordinates for the location; and

output the geographic code.

18. The computer program product of claim 17, wherein the instructions cause the computer to display, on the graphical user interface, the geographic code in a comment box and an input address mark on the map near the location.
