Abstract

The described embodiments set forth techniques for diagnostic testing a wireless device configured for cellular wireless service. A test apparatus processes data logs obtained from the wireless device, categorizes observed cellular wireless functionality issues, and provides recommended actions for a service technician and/or a user to take. Exemplary cellular wireless issues include cellular wireless service connectivity, cellular voice call stability, and cellular eSIM profile installation and transfer failures. Recommended actions can include directing a user to contact a mobile network operator with particular observations, adjusting wireless device settings, repair of a wireless device component, updating wireless device software, or replacement of the wireless device.

Claims (38)

1. A method for diagnostic testing of a wireless device, the method comprising:

by a service toolkit network-based server:

sending, to the wireless device, a request for cellular wireless metric data logs;

receiving, from the wireless device, the cellular wireless metric data logs;

processing the cellular wireless metric data logs to produce a set of test results; and

sending, to a service technician computing device, the set of test results,

wherein the set of test results categorizes cellular wireless service issues, observed by baseband wireless circuitry of the wireless device, into specific addressable areas and includes recommended actions for issue resolution.

2. The method of claim 1 , wherein the cellular wireless metric data logs include voice call connection metrics, cellular wireless network performance measurements, and cellular wireless standardized error codes.

3. The method of claim 1 , wherein the cellular wireless metric data logs include provisioning, installation, and/or transfer details for an electronic subscriber identity module (eSIM) associated with the wireless device.

4. The method of claim 1 , wherein the specific addressable areas include device issues regarding baseband software management and/or device configuration.

5. The method of claim 1 , wherein the specific addressable areas include mobile network operator issues regarding cellular wireless network performance and/or cellular service account settings.

6. The method of claim 1 , wherein the specific addressable areas include electronic subscriber identity module (eSIM) issues regarding installation, activation, configuration, and/or transfer of an eSIM.

7. The method of claim 6 , wherein the specific addressable areas include a mobile network operator (MNO) network issue affecting installation or transfer of the eSIM.

8. The method of claim 6 , wherein the specific addressable areas include a wireless device connectivity issue affecting installation or transfer of the eSIM.

9. The method of claim 6 , wherein the specific addressable areas include an eSIM transfer failure resulting from a user input or a lack thereof.

10. The method of claim 6 , wherein the specific addressable areas include an eSIM installation or transfer error resulting from a mismatch of a cellular wireless service account configuration to the eSIM.

11. The method of claim 1 , wherein a diagnostics application of the wireless device provides the cellular wireless metric data logs to a cellular wireless analyzer of the service toolkit network-based server only after obtaining user consent for release of the cellular wireless metric data logs.

12. A service toolkit network-based server comprising a cellular wireless analyzer application configured to:

send, to a wireless device, a request for cellular wireless metric data logs;

receive, from the wireless device, the cellular wireless metric data logs;

process the cellular wireless metric data logs to produce a set of test results; and

send, to a service technician computing device, the set of test results,

wherein the set of test results categorizes cellular wireless service issues, observed by baseband wireless circuitry of the wireless device, into specific addressable areas and includes recommended actions for issue resolution.

13. The service toolkit network-based server of claim 12 , wherein the cellular wireless metric data logs include provisioning, installation, and/or transfer details for an electronic subscriber identity module (eSIM) associated with the wireless device.

14. The service toolkit network-based server of claim 12 , wherein the specific addressable areas include electronic subscriber identity module (eSIM) issues regarding installation, activation, configuration, and/or transfer of an eSIM.

15. The service toolkit network-based server of claim 14 , wherein the specific addressable areas include a mobile network operator (MNO) network issue affecting installation or transfer of the eSIM.

16. The service toolkit network-based server of claim 14 , wherein the specific addressable areas include a wireless device connectivity issue affecting installation or transfer of the eSIM.

17. The service toolkit network-based server of claim 14 , wherein the specific addressable areas include an eSIM transfer failure resulting from a user input or a lack thereof.

18. The service toolkit network-based server of claim 14 , wherein the specific addressable areas include an eSIM installation or transfer error resulting from a mismatch of a cellular wireless service account configuration to the eSIM.

19. A service technician computing device configured for diagnostic testing of a wireless device, the service technician computing device comprising:

one or more antennas; and

one or more processors communicatively coupled to the one or more antennas and to a memory storing instructions that, when executed by the one or more processors, configure the service technician computing device to:

receive, by a service toolkit application, a unique hardware device identifier for the wireless device;

display a quick response (QR) code for scanning by the wireless device to initiate a diagnostics application on the wireless device;

receive, from a service toolkit network-based server, a set of test results based on cellular wireless metric data logs obtained from the wireless device and processed by a cellular wireless analyzer module of the service toolkit network-based server; and

display a summary of the set of test results,

wherein the set of test results categorizes cellular wireless service issues, observed by baseband wireless circuitry of the wireless device, into specific addressable areas and includes recommended actions for issue resolution.

20. The service technician computing device of claim 19 , wherein the specific addressable areas include electronic subscriber identity module (eSIM) issues regarding installation, activation, configuration, and/or transfer of an eSIM.
