KEY PERFORMANCE INDICATOR ANOMALY DETECTION IN TELEPHONY NETWORKS

摘要

The present invention relates to communications methods and apparatus dynamically detecting and/or mitigating anomalies in communications systems/networks. An exemplary method of operating a system to detect traffic anomalies includes the steps of: inputting input values, said input values including i) a set of key performance indicator values and ii) one or more selector values corresponding to a first anomaly group classification instance into a trained neural network; operating the trained neural network to output values corresponding to the inputted set of key performance indicator values; determining a score for the first anomaly group classification instance based on the output values of the trained neural network corresponding to the key performance indicator values, each of said output values corresponding to one key performance indicator input value; and when the score is above a first threshold determining that an anomaly condition exists with respect to the first anomaly group classification instance.
