Abstract
Real time detection of the fraudulent use of a telecommunications network is accomplished by analyzing data for each call that is occurring within the network. A signal protocol receiver is used to collect signaling protocol for each call that is occurring within the network. The Signaling protocol data is collected, decoded and formatted into call information records (CIRs). The CIRs contain various operator specified parameters for each call that is occurring within the network. The CIRs are compared to operator defined thresholds. If any of the CIRs exceeds the thresholds, an alert is generated. The alerts are stored in a database where the operator can analyze them and take the appropriate corresponding action to resolve the alert. The alerts and the CIRs are archived in a database so that trends of fraudulent use can be detected and prevented. This method of fraud detection provides for the effective analyzation of every call that is occurring within the network. Accordingly, no call go unanalyzed and ideally no fraud goes undetected. Additionally, the method does not impose an additional load on the network switching equipment and therefore results in a better quality of transmissions.
