摘要

"Fraud detection based on the speed of the attempt of the call in number of origin". This is a method of identifying fraud in a telecommunications system provided.The method includes receiving data related to a current call made to an indicator automatic originating number (ANI), where the received data shall include at least the ANI of origin,A number of billing and an identification code (step 200).The number threshold and the time interval corresponding to the identification code to the ANI are retrieved from memory (step 202).In addition, the numbers of billing for previous calls of the ANI of origin, if any, and evidence of the lengths of the corresponding calls are retrieved (step 204).A determination is made if the number of billing numbers used for the current and previous calls the ANI of origin through a previous period of time equal to or less than the interval.Time exceeds the threshold (206). If the number threshold is exceeded, a fraud alert is generated (208).If the threshold is not exceeded, creating and storing records of call to the current call using the data of the current call (step 210).
