Abstract

A system and method for recovering from a failure is disclosed. A preferred embodiment comprises downloading a first patch into a base station, installing the first patch, loading the first patch, and validating the first patch. Once the first patch has been validated, a second patch may be downloaded, installed, loaded, and verified. This incremental remediation approach allows for the conservation of resources if the system is non-recoverable, as this will become evident prior to a complete download and install is performed.

Claims

1. A method for remediating a base station, the method comprising:

implementing a first patch into the base station that has experienced a failure;

raising a trust level of the base station after the implementing the first patch; and

implementing a second patch into the base station when the first patch is successful, the second patch being different from the first patch.

2. The method of claim 1, wherein the implementing the first patch further comprises:

downloading the first patch;

validating the first patch after the downloading the first patch; and

installing the first patch.

3. The method of claim 2, wherein the installing the first patch further comprises generating an installed first patch and wherein the implementing the first patch further comprises loading the installed first patch.

4. The method of claim 2, further comprising updating a stored reference number for a component after the installing the first patch.

5. The method of claim 2, further comprising redownloading the first patch when the validating the first patch indicates a non-successful download.

6. The method of claim 2, wherein the base station is a Femto access point.

7. The method of claim 1, wherein the implementing the first patch and the implementing a second patch are performed automatically.

8. A method of automatically recovering from a failure, the method comprising:

implementing a first patch in a base station, the implementing the first patch comprising;

receiving the first patch;

validating the first patch; and

installing the first patch into a first component of the base station;

increasing a trust level of the base station after the implementing the first patch;

implementing a second patch in the base station after the implementing the first patch in the base station, the implementing the second patch comprising;

receiving the second patch;

validating the second patch; and

installing the second patch into a second component of the base station different from the first component.

9. The method of claim 8, further comprising retrying the receiving the first patch when the validating the first patch indicates a failure to successfully download.

10. The method of claim 8, wherein the implementing the first patch further comprises verifying that the first patch was installed.

11. The method of claim 8, further comprising verifying that the first patch was installed, wherein the installing the first patch is performed a second time when the verifying that the first patch was installed indicates a failure.

12. The method of claim 8, further comprising ranking the first patch and the second patch in accordance with a priority.

13. A method for failure recovery, the method comprising:

receiving a first download at a wireless base station;

installing the first download into the wireless base station;

loading the installed first download into the wireless base station;

validating the loading the installed first download;

changing a trust level of the wireless base station when the validating the loading the installed first download indicates a successful loading;

receiving a second download at the wireless base station when the validating the loading the installed first download indicates a successful loading; and

installing the second download at the wireless base station.

14. The method of claim 13, further comprising:

validating the first download after the receiving the first download; and

retrying the receiving the first download when the validating the first download indicates a failure.

15. The method of claim 13, further comprising:

verifying the installing the first download; and

reinstalling the first download when the verifying the installing the first download indicates a failure.

16. The method of claim 13, further comprising updating a reference value of a component after the installing the first download.

17. The method of claim 13, wherein the first download and the second download install different components within the wireless base station.

18. A method of transmitting remediation data, the method comprising:

transmitting a first patch from a transmission station, the first patch being a first subset of a series of patches that are related to each other;

receiving a request for a second patch to be transmitted at the transmission station;

increasing a trust level based at least in part on the receiving the request for the second patch; and

transmitting the second patch from the transmission station, the second patch being a second subset of the series of patches and also being different from the first patch.

19. The method of claim 18, wherein the first patch comprises remediation data for a first component and the second patch comprises remediation data for a second component different from the first component.

20. The method of claim 18, wherein the transmission station is an operations, administration, and maintenance system.

21. The method of claim 18, wherein the first subset comprises two or more patches.

22. A base station comprising:

a processor with a first implementing unit, the first implementing unit configured to implement a first patch into the base station that has experienced a failure, wherein the processor is also configured to receive an updated trust level after the implanting the first patch; and

a second implementing unit, the second implementing unit configured to implement a second patch into the base station when the first patch is successful, the second patch being different from the first patch.

23. The base station of claim 22, wherein the first implementing unit further comprises:

a downloading unit, the downloading unit configured to download the first patch;

a download validation unit, the download validation unit configured to validate the first patch; and

an installation unit, the installation unit configured to install the first patch.

24. The base station of claim 23, wherein the base station is a Femto access point.

25. A base station comprising:

a receiving unit configured to receive a first download at a base station;

an installation unit configured to install the first download into the base station;

a loading unit configured to load the installed first download into the base station; and

a load validation unit configured to validate the load of the installed first download;

wherein the receiving unit is also configured to receive a change in an assigned trust level after load validation unit has validated the load the of the installed first download, wherein the receiving unit is also configure to receive a second download at the base station when the load validation unit indicates a successful loading, and wherein the installation unit is also configured to install the second download at the base station.

26. The base station of claim 25, further comprising a receive validation unit configured to validate the first download.

27. The base station of claim 25, further comprising a verification unit configured to verify the install of the first download.
