Methods, systems and computer program products for detecting anomalies in a telecommunications network

Abstract:

Methods for detecting anomalies in a telecommunications network are provided. The methods include calculating a call duration for each of a plurality of calls associated with a corresponding call detail record (CDR). Each CDR provides details associated with a single call in a plurality of fields. Each of the plurality of calls are categorized based on the calculated call duration for each call such that each of the plurality of calls is assigned to a duration bin, each duration bin including calls having similar calculated call durations. The CDRs are grouped using the duration bins and at least one carrier and/or a telecommunications provider. A plurality of summary statistics are calculated for each of the plurality of CDR groups. The calculated plurality of summary statistics are analyzed to determine whether an anomaly is present. Among other remedial measures, an external ticket may be generated informing affected carriers when an anomaly is present.
