Using User Equipment Data Clusters and Spatial Temporal Graphs of Abnormalities for Root Cause Analysis

A method comprising:

• obtaining, at a computing device comprising a processor, user equipment data comprising values for performance metrics for user equipment, wherein the user equipment is connected to a cellular network and is experiencing a failure;
• applying, by the processor, a filter having a threshold to the user equipment data to obtain a subset of records from the user equipment data, wherein the threshold specifies a value for the performance metrics;
• determining, by the processor, if the threshold is to be adjusted based on a number of records included in the subset of records;
• in response to a determination that the threshold is to be adjusted, generating, by the processor, a plurality of data clusters by applying a clustering algorithm to a record set, determining a centroid for each of the plurality of data clusters, and adjusting the threshold based on the centroid for each of the plurality of data clusters;
• and
• in response to a determination that the threshold is not to be adjusted, adding, by the processor, the records of the subset of records to the record set, correlating the records of the subset of records based on a key to obtain a filtered and correlated version of the record set, and generating, based on the filtered and correlated version of the record set, a spatial temporal graph of abnormalities associated with the cellular network, wherein a root cause of the failure can be determined based on the spatial temporal graph of abnormalities.

A computer storage medium having computer-executable instructions stored thereon that, when executed by a processor, cause the processor to perform operations comprising:

• obtaining user equipment data comprising values for performance metrics for user equipment, wherein the user equipment is connected to a cellular network and is experiencing a failure;
