Identifying inbound call traffic anomalies in telecommunications system
A recently granted patent (Publication Number: US11849064B1) discloses a method for identifying inbound call traffic anomalies in a telecommunications system. The method involves receiving expected values for data associated with call detail records and determining if observed values fall outside defined upper and lower thresholds for each metric. If an observed value is outside the thresholds, a set of residuals is selected based on aggregated data in the call detail records. An anomaly score is computed based on these residuals, and the need for multiple anomalous alerting windows is assessed to create an alert. If no multiple windows are needed, an anomaly in the inbound call traffic is declared.
Furthermore, the method includes steps for extending a list of recent inbound traffic anomalies, determining the need for multiple alerting windows based on the extended list, and preprocessing data for forecasting and computing standard deviations. The anomaly score calculation involves obtaining scaled observed and middle values, determining residuals, and setting an additive constant based on the observed value's position relative to a lower boundary. The defined upper and lower thresholds include criteria related to observed attempts and successes. The system also includes provisions for creating alerts related to identified anomalies and implementing remedial processes associated with the alerted anomalies, enhancing the efficiency of anomaly detection and response in telecommunications systems.
