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.

Abstract: Service observing equipment monitors, detects and makes call records from digital and audio information on an individual call basis. The observation equipment can monitor both a Signalling System Seven (SS #7) and a CCITT #7 in which data packets are transmitted along the high speed data links separated from the telecommunication audio channels. The call record indicates how trouble free and efficiently (or how troubled and inefficiently) individual calls are processed by the telecommunication network. A plurality of separate memory locations are assigned on an individual call basis, for the duration of a given call, to store data received over any of many data links and communication channels relative to that given call. After the call has terminated, the accumulated data is analyzed to determine the call's final disposition. A call record is restored in memory for reports and/or transmitted to a printer or another processor.
