Abstract: A method for controlling telephone fraud of the type whereby a caller places calls or accesses services via unauthorized use of a credit card number or other authorization number. For such control, an initial call using the number and meeting a certain primary criterion (such as placement to a geographical area known to receive numerous fraudulent calls) is intercepted and it is determined whether or not that call is an authentic use of the number. If authentic, other calls are then allowed without interception, even though they may meet the primary criterion, unless or until a secondary criterion is met. Meeting the secondary criterion (which may relate to calling patterns indicative of fraud) also causes a call to be intercepted and a determination made as to whether the use is authentic. For interception due to either criterion, if the call is determined to be inauthentic, the authorization number may be removed from service.

Abstract: In a telecommunication network, a DATA ACCESS POINT (DAP) database is used to route traffic between originating calling stations and terminating called stations for special service processing calls. The traffic or routing data are collected and converted by a traffic statistics processor into statistics data. The statistics data are provided to the management of the network. Some of the statistics data are converted by an INTEGRATED NETWORK MANAGEMENT SYSTEM (INMS) compiler processor into reports which may be provided to subscribers of the special call processing service in real time or on a delay basis. If a subscriber has subscribed to the special call processing service on a real time basis, he can update certain parameters of the database to reallocate the percentage of calls to be directed to the different called station staffed by his operators.
