    Abstract: A system (100) for preventing telecommunications fraud comprising a database (114) and fraud control center (118) having at least one processor to receiv e and store numbers representing terminating ANIs in the database (114) that have generated a fraud alert, to check the database (114) to determine if th e dialed terminating ANI matches a stored number. The stored numbers include a t least a portion of the terminating ANI and at least one variable length character, and are accessible to block subsequent calls directed at the respective terminating ANIs. The at least one variable length character also matches one or more or any corresponding or subsequent characters in the dialed terminating ANI. A match between the dialed terminating ANI and a stored number initiate a block of the dialed call.

    Abstract: A method and device for preventing fraud in international calls in a long- distance telecommunications system, where selected customers can avoid fraud control blocks and greater granularity is achieved in blocking international destinations. In the method and device, an override flag is created in the records of the Billing Number Screening (BNS) database (410). When a call is made using a billing number whose corresponding record has the override flag set (417), the call is not stopped by fraud control blocks on certain international destinations. In addition, international destinations can be blocked with greater specificity because a Country Set Logic (CSET) field (425, 435) is added to the International City Code Database. The addition of CSET (425, 435) to this database allows particular international city destinations to be blocked from certain origin points.

    Abstract: A system and device for blocking fraudulent special service calls (Fig. 3) i n a long distance telephone system is disclosed. The Automatic Number Identifiers (ANIs) of originating numbers within Local Exchange Carriers (LECs) are blocked from calling certain special service call numbers by including the ANI in the special service call number record in the long distance carrier's Service Management System (SMS) database. ANIs to be blocked are selected by fraud control based on certain network traffic flow thresholds. When the switching elements in the long distance carrier retriev e an SMS record for a particular special service call, it is determined whethe r the origin of the call corresponds to an ANI in the SMS record. If it does, the call is blocked.

    Abstract: A method for using at least one Bad Billed Number Record (BBN) to detect fraud in a telecommunication system includes the steps of generating the at least one BBN for each call attempt made using a billing product, when the call attempt satisfies any one of a plurality of fraud criteria; storing the at least one BBN in a storage queue for later retrieval; and retrieving and analyzing the at least one BBN to increment a plurality of fraud control counters according to the analysis. A system for using a plurality of BBNs to detect fraud in a telecommunications system includes a network operator service platform (OSP) for generating BBNs based on received call attempts; a network information concentrator (NIC) for temporarily storing the generated BBNs; and a fraud monitoring system for retrieving the stored BBNs, filtering out unidentifiable BBNs, analyzing identifiable BBNs, and generating alarms based on the analysis.

    Abstract: A method and device (100) for preventing fraud in collect calls from a domestic origin point (120) to an international terminating point (160) through a long-distance telecommunications system is described. In the syste m and method, a screening for international calls database (170) is added to t he call processing system platform (150). The screening of international calls database (170) contains records keyed by country codes, and each record has a blocked collect call field using the destination numbers that are blocked fr om receiving collect calls. When a domestic-to-international collect call is made, the record corresponding to the country code of the international terminating point of the collect call is retrieved from the screening for international calls database (170). This record is checked to determine if t he destination number of the collect call matches any destination numbers liste d in the blocked collect call field of the country code database record. If there is a match, the call is blocked.
