Abstract

A wireless expert system connects to a plurality of diagnostic modules and is configured to receive a complaint from a user of a wireless device, the complaint comprising data and attributes. The expert system executes a two-phase process. In the first phase, the complaint is analyzed to determine which of the diagnostic modules should be run. In the second phase, the selected diagnostic modules are run, and the user is provided with a recommended corrective action. If the action is successful, the expert system is updated with the successful resolution, providing additional assurance for future analyses.

Claims

1. A diagnostic system for diagnosing faults in a wireless device, the diagnostic system comprising:

a processor;

a module interface communicatively coupled to the processor and configured to communicatively couple the processor to a plurality of diagnostic modules;

an input/output module communicatively coupled to the processor and configured to communicatively couple the processor to a user testing the wireless device;

a tangible storage medium having stored thereon a data repository, the data repository configured to correlate wireless device faults with probable causes;

the tangible storage medium further having stored thereon software instructions executable by the processor that, when executed, are configured to instruct the processor to;

receive a complaint from the user, the complaint comprising data and attributes;

compare the complaint data and complaint attributes respectively to records of the data repository, and based on the comparison, select one or more diagnostic modules to query for a proposed resolution;

provide at least one of the complaint data or complaint attributes to the selected module or modules over the module interface;

receive from the module, over the module interface, a diagnostic report including at least one proposed resolution;

ranking the proposed resolutions according to probable causation of the complaint; and

providing to the user, over the input/output module, a recommended resolution.

2. The diagnostic system of claim 1 wherein the software instructions further comprise instructions to receive from the user, over the user interface, a report on the result of the recommended resolution, and to update the data repository in response to the report.

3. The diagnostic system of claim 2 wherein the software instructions further comprise instructions to, upon receiving a report of a failed resolution, to iteratively provide the next-most-probable resolution until the report indicates success or the proposed resolutions are exhausted.

4. The diagnostic system of claim 1 wherein the diagnostic modules comprise a hardware diagnostic module, a third-party application module, a network diagnostic module, and a firmware compliance module.

5. The diagnostic system of claim 4 wherein the software instructions are further configured to instruct the processor to receive input from a human decision science team.

6. The diagnostic system of claim 5 wherein the input from the decision science team includes weight values for proposed resolutions.

7. The diagnostic system of claim 1 wherein the diagnostic modules includes at least a hardware diagnostic module configured to analyze the functionality of hardware of the wireless device.

8. The diagnostic system of claim 7 wherein the hardware diagnostic module comprises a user input form designed to collect user-discoverable data about the hardware.

9. The diagnostic system of claim 7 wherein the hardware diagnostic module is configured to tether to the wireless device and perform electronic diagnostics.

10. The diagnostic system of claim 1 wherein the diagnostic modules include at least a third-party application module configured to receive a list of third-party applications installed on the wireless device and compare the list to a master table of third-party applications known to cause errors with wireless devices.

11. The diagnostic system of claim 10 wherein the third-party application module is further configured to detect corrupted third-party applications.

12. The diagnostic system of claim 10 wherein the third-party application module is further configured to receive a plurality of third-party applications and to identify conflicts between third-party applications.

13. The diagnostic system of claim 1 wherein the diagnostic modules include at least a network diagnostic module configured to test network operations with a carrier network.

14. The diagnostic system of claim 13 wherein the network diagnostic module includes a third-party application configured to provide data related to network functionality.

15. The diagnostic system of claim 13 wherein the network diagnostic module is configured to detect a wireless tower outage.

16. The diagnostic system of claim 13 wherein the network diagnostic module is configured to perform wireless communication tests with the carrier network to evaluate the reliability and availability of the carrier network.

17. The diagnostic system of claim 1 wherein the diagnostic modules include at least a firmware compliance module configured to compare the installed firmware to a master list of best firmware versions.

18. A method of diagnosing a fault on a wireless device, performable by an expert system, the method comprising the steps of:

receiving a complaint;

based on the complaint, selecting at least one diagnostic module from a plurality of available diagnostic modules for analysis of the complaint;

providing the complaint to the selected diagnostic modules;

receiving from the selected diagnostic modules at least one recommended resolution;

ranking the recommended resolutions according to probability; and

providing the most probable recommended resolution as a recommended action for correcting the fault.

19. The method of claim 18 wherein selecting at least one diagnostic module includes selecting at least one diagnostic module from the group consisting of a hardware diagnostic module, a third-party application module, a network diagnostic module, and a firmware compliance module.

20. The method of claim 18 further comprising the steps of receiving input from a human decision science team and integrating the input into the ranking step.

21. The method of claim 20 wherein receiving input from the human decision science team includes receiving weighting values for the recommended resolutions.

22. A wireless device expert system for evaluating faults in a wireless device, the expert system comprising:

a logic unit configured to communicatively couple to a plurality of diagnostic modules;

a hardware diagnostic module configured to evaluate hardware functionality of the wireless device;

a third-party application module configured to evaluate third-party applications installed on the wireless device;

a network diagnostic module configured to test connectivity between the wireless device and a carrier network;

a firmware compliance module configured to evaluate the installed firmware on the wireless device;

a data repository including statistical correlations between faults and causes;

wherein the logic unit is configured to;

receive a complaint indicating a fault with the wireless device;

based on the complaint, select at least one diagnostic module to query for potential resolutions;

query the selected diagnostic modules;

receive from the selected diagnostic modules at least one recommended resolution;

rank the recommended resolutions according to probability provided by the data repository; and

provide the first-ranked resolution as the recommended resolution.

23. The expert system of claim 22 wherein the logic unit is further configured to receive a results report indicating the success of the recommended resolution and to update the data repository based on the success of the resolution.

24. The expert system of claim 22 wherein the logic unit is further configured to determine whether the recommended resolution was successful, and upon determining that the recommended resolution was not successful, iteratively provide the next-most-probable recommended resolution until the resolution is determined to be successful or the list of recommended resolutions is exhausted.
