Abstract

One or more implementations can include methods, systems and computer readable media for client location discovery. In some implementations, the method can include receiving, at an access point, a location discovery request message from a client and sending a request from the access point to a location server requesting location information for the client, when a location server is available. The method can also include receiving location information from the location server, when a location server is available and providing the access point location as location information, when a location server is not available. The method can further include sending the location information as a response to the client.

Claims

1. A method comprising:

receiving, at an access point, a location discovery request message from a client;

sending a request from the access point to a location server requesting location information for the client, when a location server is available;

receiving location information from the location server, when a location server is available;

providing the access point location as location information, when a location server is not available; and

sending the location information as a response to the client.

2. The method of claim 1, wherein the location discovery request message is a multicast request sent over a reserved link-local multicast address and the access point snoops the multicast request.

3. The method of claim 1, wherein the location discovery request message specifies a type of location data being requested.

4. The method of claim 1, wherein the location discovery request message specifies a frequency for updating the location information to the client.

5. The method of claim 1, wherein the response is sent as a unicast message from the access point to the client.

6. The method of claim 1, wherein the client includes a client device.

7. The method of claim 1, wherein the client includes one or more client applications.

13. The system of claim 1, wherein the client includes a client device.

14. The system of claim 1, wherein the client includes one or more client applications.

8. A system comprising one or more processors configured to perform operations including:

receiving, at an access point, a location discovery request message from a client;

sending a request from the access point to a location server requesting location information for the client, when a location server is available;

receiving location information from the location server, when a location server is available;

providing the access point location as location information, when a location server is not available; and

sending the location information as a response to the client.

9. The system of claim 8, wherein the location discovery request message is a multicast request sent over a reserved link-local multicast address and the access point snoops the multicast request.

10. The system of claim 8, wherein the location discovery request message specifies a type of location data being requested.

11. The system of claim 8, wherein the location discovery request message specifies a frequency for updating the location information to the client.

12. The system of claim 8, wherein the response is sent as a unicast message from the access point to the client.

15. A nontransitory computer readable medium having stored thereon software instructions that, when executed by a processor of a wireless controller, cause the processor to perform operations including:

receiving, at an access point, a location discovery request message from a client;

sending a request from the access point to a location server requesting location information for the client, when a location server is available;

receiving location information from the location server, when a location server is available;

providing the access point location as location information, when a location server is not available; and

sending the location information as a response to the client.

16. The nontransitory computer readable medium of claim 15, wherein the location discovery request message is a multicast request sent over a reserved link-local multicast address and the access point snoops the multicast request.

17. The nontransitory computer readable medium of claim 15, wherein the location discovery request message specifies a type of location data being requested.

18. The nontransitory computer readable medium of claim 15, wherein the location discovery request message specifies a frequency for updating the location information to the client.

19. The nontransitory computer readable medium of claim 15, wherein the response is sent as a unicast message from the access point to the client.

20. The nontransitory computer readable medium of claim 15, wherein the client includes one or more of a client device and one or more client applications.
