Abstract

The disclosure relates to cloud-based mobile discovery networks. For example, a mobile discovery network may include a network responsive to successful watermark detection or fingerprint extraction. One claim recites a cloud-based computing resolver cell in a mobile discovery network, the mobile discovery network having a cloud-based traffic router for forwarding requests from remote devices. The resolver cell includes: memory for storing response information; one or more processors programmed for: combine results from a third party inquiry, a traffic router health check, and an internal component or processing check within a certain time period determine whether to enter into a stabilization mode; entering the stabilization mode when a determination indicates stabilization is warranted; verifying, for a predetermined period, the status of the resolver cell before exiting the stabilization mode. Of course other claims and combinations are provided as well.

Claims

1. A cloud-based computing resolver cell in a mobile discovery network, the mobile discovery network comprising a cloud-based traffic router for forwarding requests from remote devices, said resolver cell comprising:

memory for storing response information;

one or more processors programmed for;

combining results from a third party inquiry, a traffic router health check, and an internal component or processing check within a certain time period to determine whether to enter into a stabilization mode;

entering the stabilization mode when a determination indicates stabilization is warranted;

verifying, for a predetermined period, the status of said resolver cell before exiting the stabilization mode.

2. The resolver cell of claim 1 in which the internal component or processing check comprises a storage availability check.

3. The resolver cell of claim 1 further comprising restarting the predetermined period when the status indicates that operational requirements are not met.

4. The resolver cell of claim 1, in which said one or more processors are programmed for:

when not in the stabilization mode, communicating a response for a mobile device upon receipt of a successful watermark detection or fingerprint extraction, the response being indexed in the response information according to watermark information or fingerprint information.

5. The resolver cell of claim 4, further comprising a fingerprint extractor for exacting a fingerprint or a digital watermark detector for detecting a digital watermark from digital content data.

6. The resolver cell of claim 5 in which the digital content data comprises a filtered version of captured digital content data, the captured digital content data having been captured by a mobile device.

7. The resolver cell of claim 1 in which the internal component or processing check comprises a read or write to storage.

8. The resolver cell of claim 1 in which the internal component or processing check comprises setting a queue.

9. The resolver cell of claim 1, in which the health check comprises a health check associated with said resolver cell which is issued by said resolver cell to the traffic router.

10. The resolver cell of claim 9 in which upon issuing a first health check error, said one or more processors control tracking health checks for n additional traffic router health checks, where n comprises an integer, and if any of the following are true said one or more processors cause said resolver cell to enter into the stabilization mode:

i) did a predetermined percentage of the n additional traffic router health checks fail;

ii) did any of the n additional traffic router health checks fail within a just expired time period; and

iii) did the very last health check of the n additional traffic router health checks fail.

11. A method of controlling a cloud-based computing resolver cell in a mobile discovery network, the mobile discovery network comprising a cloud-based traffic router for forwarding requests from remote devices, the resolver cell comprising memory for storing response information, said method comprising:

using one or more programmed processors, utilizing results from a third party inquiry, a traffic router health check, and an internal component or processing check within a certain time period to determine whether to enter into a stabilization mode;

under control of one or more programmed processors, causing the resolver cell to enter a stabilization mode when a determination indicates stabilization is warranted;

determining, for a predetermined period, the status of the resolver cell before exiting the stabilization mode.

12. The method claim 11 in which the internal component or processing check comprises a storage availability check.

13. The method of claim 11 further comprising restarting the predetermined period when the status indicates that operational requirements are not met.

14. The method of claim 11 further comprising, when not in the stabilization mode, communicating a response for a mobile device upon receipt of a successful watermark detection or fingerprint extraction, the response being indexed in the response information according to watermark information or fingerprint information.

15. The method of claim 14, in which the resolver cell comprises a fingerprint extractor for exacting a fingerprint or a digital watermark detector for detecting a digital watermark from digital content data.

16. The method of claim 15 in which the digital content data comprises a filtered version of captured digital content data, the captured digital content data having been captured by a mobile device.

17. The method of claim 11 in which the internal component or processing check comprises a read or write to storage.

18. The method of claim 11 in which the internal component or processing check comprises setting a queue.

19. The method of claim 11, in which the health check comprises a health check associated with the resolver cell which is issued by the resolver cell to the traffic router.

20. The method of claim 19 further comprising upon issuing a first health check error, monitoring health checks for n additional traffic router health checks, where n comprises an integer, and if any of the following are true causing the resolver cell to enter into the stabilization mode:

i) did a predetermined percentage of the n additional traffic router health checks fail;

ii) did any of the n additional traffic router health checks fail within a just expired time period; and

iii) did the very last health check of the n additional traffic router health checks fail.

21. A cloud-based computing resolver cell in a mobile discovery network, the mobile discovery network comprising a cloud-based traffic router for forwarding requests from remote devices, said resolver cell comprising:

means for storing response information;

means for determining whether to enter into a stabilization mode based on results from a third party inquiry, a traffic router health check, and an internal component or processing check within a certain time period;

means for initiating the stabilization mode when said means for determining determines that stabilization is warranted;

means for monitoring, for a predetermined period, the status of said resolver cell before exiting the stabilization mode.

22. The resolver cell of claim 21 further comprising means for restarting the predetermined period when said means for monitoring indicates that operational requirements are not met.

23. The resolver cell of claim 21, further comprising:

means for communicating a response for a mobile device upon receipt of a successful watermark detection or fingerprint extraction, the response being indexed in the response information according to watermark information or fingerprint information, and in which said means for communicating remains operational when the resolver cell is not in the stabilization mode.

24. The resolver cell of claim 23, further comprising means for fingerprint extraction or means for detecting a digital watermark from digital content data.

25. The resolver cell of claim 21, in which the health check comprises a health check associated with said resolver cell which is issued by said resolver cell to the traffic router.

26. The resolver cell of claim 25 further comprising means for monitoring health checks for n additional traffic router health checks, where n comprises an integer, and if any of the following are true said means for initiating causes said resolver cell to enter into the stabilization mode:

i) did a predetermined percentage of the n additional traffic router health checks fail;

ii) did any of the n additional traffic router health checks fail within a just expired time period; and

iii) did the very last health check of the n additional traffic router health checks fail.
