Abstract

Claims (89)

1. At least one non-transitory computer-readable storage medium storing instructions to test an update associated with a radio access network (RAN) of a wireless telecommunication network, which, when executed by at least one data processor of a system, cause the system to:

periodically scan the RAN of the wireless telecommunication network to obtain an indication of a hardware status associated with the RAN and a software status associated with the RAN,

wherein the RAN includes a gNodeB, an eNodeB, and an open radio access network (ORAN);

determine whether there is the update to the hardware status associated with the RAN or the software status associated with the RAN;

upon determining there is the update to the hardware status associated with the RAN or the software status associated with the RAN, obtain from a first database an indication of a remote radio head configured to test the update;

based on the indication of the remote radio head, obtain from a second database multiple mobile devices configured to test the update;

test the update by causing the remote radio head to send a communication to a mobile device among the multiple mobile devices;

obtain logs associated with the communication,

wherein the logs are generated by a component of the wireless telecommunication network and the mobile device among the multiple mobile devices; and

based on the logs, determine whether the update passes the test.

2. The at least one non-transitory computer-readable storage medium of claim 1 , comprising instructions to:

based on the update, determine a first subset of mobile devices among the multiple mobile devices configured to test the update;

based on the update, obtain from a third database multiple test cases associated with the RAN,

wherein the multiple test cases are configured to test the update,

wherein the multiple test cases include a band and a generation of wireless technology; and

based on the multiple test cases and the first subset of mobile devices, select a subset of the multiple test cases to run, thereby reducing a number of test cases to run.

3. The at least one non-transitory computer-readable storage medium of claim 1 , comprising instructions to:

translate the logs from a machine-readable format to a human-readable format; and

store the human-readable format.

4. The at least one non-transitory computer-readable storage medium of claim 1 , wherein the instructions to periodically scan the RAN comprise instructions to:

directly access a node associated with the RAN; or

query a database associated with the RAN.

5. The at least one non-transitory computer-readable storage medium of claim 1 , comprising instructions to:

determine that a component of the wireless telecommunication network has failed, wherein the failure prevents testing of the update; and

store an indication of the update for testing when the failure is resolved.

6. The at least one non-transitory computer-readable storage medium of claim 1 , comprising instructions to:

based on the update, determine a subset of mobile devices among the multiple mobile devices configured to test the update.

7. The at least one non-transitory computer-readable storage medium of claim 1 , comprising instructions to:

obtain a first indication to test the multiple mobile devices, wherein the first indication includes a generation of wireless technology and a band;

obtain a second indication to test the multiple mobile devices, wherein the second indication includes the generation of wireless technology; and

based on the first indication and the second indication, select the multiple mobile devices, wherein a number of the selected multiple mobile devices is less than a number of multiple mobile devices selected based on only the first indication or only the second indication.

8. A method comprising:

scanning a RAN associated with a wireless telecommunication network to obtain an indication of a hardware status associated with the RAN and a software status associated with the RAN,

wherein the RAN includes a gNodeB, an eNodeB, and an open radio access network (ORAN);

determining whether there is an update to the hardware status associated with the RAN or the software status associated with the RAN;

upon determining there is the update to the hardware status associated with the RAN or the software status associated with the RAN, obtaining from a first database an indication of a remote radio head configured to test the update;

based on the indication of the remote radio head, obtaining from a second database multiple user equipment (UEs) configured to test the update;

testing the update by causing the remote radio head to send a communication to a UE among the multiple UEs;

obtaining logs associated with the communication,

wherein the logs are generated by a component of the wireless telecommunication network and the UE among the multiple UEs; and

based on the logs, determining whether the update passes the test.

9. The method of claim 8 , comprising:

based on the update, determining a first subset of UEs among the multiple UEs configured to test the update;

based on the update, obtaining from a third database multiple test cases associated with the RAN,

wherein the multiple test cases are configured to test the update,

wherein the multiple test cases include a band and a generation of wireless technology; and

based on the multiple test cases and the first subset of UEs, determining a subset of the multiple test cases to run, thereby reducing a number of test cases to run.

10. The method of claim 8 , comprising:

translating the logs from a machine-readable format to a human-readable format; and

storing the human-readable format.

11. The method of claim 8 , wherein scanning the RAN comprises:

directly accessing a node associated with the RAN; or

querying a database associated with the RAN.

12. The method of claim 8 , comprising:
