Abstract

A computer-implemented method that includes receiving a location from a location aware access device and an IP address of a network device to which the location aware access device is connected, receiving a request that includes the IP address of the network device from a location unaware access device that is connected to the network device, determining a geographic location for the location unaware access device based on the IP address of the network device and the location received from the location aware access device, selecting information responsive to the request from the location unaware access device based at least in part on the geographic location, and providing the selected information to the location unaware access device.

Claims

1. A computer-implemented method, comprising:

receiving a first communication from a location aware access device, the first communication being sent from an Internet IP address of a network device to which the location aware access device is connected according to a local area network (LAN) IP address of the location aware access device, wherein the first communication includes a geographic location sensed by the location aware access device;

creating a record in memory associating the Internet IP address of the network device with the geographic location sent via the Internet IP address from the location aware access device;

receiving a request from the same Internet IP address of the network device, the request being sent via the network device from a location unaware access device that is connected to the network device according to a LAN IP address of the local area network for the location unaware access device, wherein the network device translates between the Internet IP address of the network access device and the LAN IP addresses of the access devices;

determining a geographic location for the location unaware access device based on the Internet IP address of the network device from which both the request from the location unaware access device was received and the location was received from the location aware access device by retrieving, based on the Internet IP address, the record in memory associating the Internet IP address of the network device with the geographic location sent via the Internet IP address from the location aware access device;

selecting information responsive to the request from the location unaware access device based at least in part on the geographic location; and

sending the selected information to the location unaware access device.

2. The method of claim 1, wherein the selected information comprises an advertisement selected based on the location.

3. The method of claim 1, comprising:

receiving a second communication from a different Internet IP address of the network device after sending the selected information to the location unaware device, the second communication including an updated location;

receiving another request sent by the location unaware device from the different Internet IP address of the network device; and

determining a geographic location of the location unaware device by correlating the updated location with the location unaware device based on the updated location and the other request coming from the same Internet IP address.

4. A computer-implemented method, comprising:

receiving a request from a location unaware access device that is connected to a network device, wherein the request includes an IP address of the network device;

determining a geographic location for the location unaware access device based on the IP address of the network device and an analysis of one or more records stored in a data repository each of which associate a location received from a location aware access device previously connected to the network device and the IP address of the network device, wherein the geographic location and the request are received from the same IP address of the network device and are sent by the location aware access device and the location unaware access device, respectively, and wherein the determination is based on the geographic location and the request being sent from the same IP address of the network device;

selecting information responsive to the request from the location unaware access device based at least in part on the geographic location; and

sending the selected information to the location unaware access device.

5. The method of claim 4, wherein the selected information comprises an advertisement selected based on the location.

6. The method of claim 4, comprising:

receiving an updated location sensed by the location aware access device from an updated IP address of the network device;

receiving a request sent by the location unaware access device from the updated IP address of the network device; and

determining that the location unaware access device is at the updated location based on the location unaware access device sharing the updated IP address with the location aware access device.

7. The method of claim 4, wherein determining the geographic location for the location unaware access device further comprises determining that the one or more records stored in the data repository were received within a predetermined period from a set time.

8. The method of claim 7, wherein the set time is the time the request from the location unaware device is received.

9. The method of claim 7, wherein the set time is a time when the one or more records are analyzed to determine the location, and is independent of the time the request from the location unaware access device is received.

10. The method of claim 4, wherein determining the geographic location for the location unaware access device further comprises determining that a plurality of locations associated with the IP address of the network device in the data repository are not distributed over a geographic area larger than a threshold.

11. The method of claim 10, further comprising determining the location of the location unaware access device from the average of the plurality of locations.

12. The method of claim 10, further comprising determining the location of the location unaware access device from the most probable of the plurality of locations.

13. A computer system, comprising:

one or more memories storing instructions; and

one or more processors coupled to the one or more memories and executing the instructions stored thereon in order to perform the following;

receiving a first communication from a location aware access device, the first communication being sent from an Internet IP address of a network device to which the location aware access device is connected according to a local area network (LAN) IP address of the location aware access device, wherein the first communication includes a geographic location sensed by the location aware access device;

creating a record in memory associating the Internet IP address of the network device with the geographic location sent via the Internet IP address from the location aware access device;

receiving a request from the same Internet IP address of the network device, the request being sent via the network device from a location unaware access device that is connected to the network device according to a LAN IP address of the local area network for the location unaware access device, wherein the network device translates between the Internet IP address of the network access device and the LAN IP addresses of the access devices;

determining a geographic location for the location unaware access device based on the Internet IP address of the network device from which both the request from the location unaware access device was received and the location was received from the location aware access device by retrieving, based on the Internet IP address, the record in memory associating the Internet IP address of the network device with the geographic location sent via the Internet IP address from the location aware access device;

selecting information responsive to the request from the location unaware access device based at least in part on the geographic location; and

sending the selected information to the location unaware access device.

14. A computer system, comprising:

one or more memories storing instructions; and

one or more processors coupled to the one or more memories and executing the instructions stored thereon in order to perform the following;

receiving a request from a location unaware access device that is connected to a network device, wherein the request includes an IP address of the network device;

determining a geographic location for the location unaware access device based on the IP address of the network device and an analysis of one or more records stored in a data repository each of which associate a location received from a location aware access device previously connected to the network device and the IP address of the network device, wherein the geographic location and the request are received from the same IP address of the network device and are sent by the location aware access device and the location unaware access device, respectively, and wherein the determination is based on the geographic location and the request being sent from the same IP address of the network device;
