Patent

CA 2410012

A method of identifying fraud in a telecommunications system, the method including receiving data related to a current call placed from an originating ANI to a terminating ANI, where the received data includes the terminating ANI and a billing number used to place the call. Billing numbers for prior calls to the terminating ANI, if any, and corresponding indicia of the times of the calls are retrieved. A determination is made of whether the number of billing numbers used for the current and prior calls to the terminating ANI over a prior period of time falling within a time interval satisfies a threshold. If the threshold is satisfied, a fraud alert is generated.

L'invention concerne un procédé d'identification de fraude dans un système de télécommunication. Ledit procédé consiste à recevoir les données relatives à un appel ponctuel passé d'un indicateur de numéro automatique ANI à un ANI terminal, les données reçues comprenant l'ANI terminal et un numéro de facturation utilisé pour le passage de l'appel. Les numéros de facturation pour les appels antérieurs à l'ANI terminal, le cas échéant, et les repères correspondants, relatifs aux heures des appels sont extraits. Il est déterminé si le nombre de numéros de facturation utilisés pour les appels en cours et antérieurs de l'ANI terminal sur une période de temps antérieure se trouvant dans un intervalle de temps, correspond à un seuil. Si c'est le cas, un alarme de fraude est générée.
