A call intercept process (CIP) for calling card calls originating from an international country and terminating to high fraud domestic USA, and Canada locations. When a call is placed via a calling card and terminates to a high fraud domestic location, the call is optionally screened against a database which keys on international originating country access numbers. Whether this screening implemented, the call is routed to a first level operator in order to verify the billing account information of the caller as an authorized user. This verification is based on customer and business name, address, zip code, and phone number. If the caller passes verification, a CIP process automatically overrides the calling card from any future Intercepts. If caller fails account verification, the a CIP process automatically places the card in a âLOCKED STATUS MODEâ which mode indicates that any additional calls based on that card be intercepted regardless of termination. At any time the caller passes verification, the card is lifted and placed in an override process via the CIP process.

Terminating number screening to block portable billing products from terminating to a designated high fraud domestic or international terminating numbers. When a call is placed and it is billed to a portable billing product, the dialed digits of the terminating number is verified against the terminating number screening database. If the sequence of dialed digits is found in the terminating number screening database, the call is denied. The caller is then informed that they cannot place a call to this destination and asked if there is another terminating number they wish to call. If the sequence of dialed digits is not found in the terminating number screening database, the call is allowed to process without interruption. The purpose of this functionality is to protect the Operator Service network from repeated fraudulent calling to individual telephone line numbers either international or domestic. The unique characteristic of this function is the ability to select a single terminating number for blocking, based on product type, such as a calling card, Credit card, and other billing options.

A system and method for detecting and preventing a fraudulent telephone call in telecommunication system is provided. First, a terminating number of a first call and a originating number of a second call are received from a telecommunication network. The terminating number of the first call is compared with the originating number of the second calls which are originated within a predetermined time period from a termination of the first call. After comparison, it is determined whether the first and the second calls are fraudulent telephone call.

A method and device for preventing fraud in special service calls from an international origin point to a domestic terminating point through a long-distance telecommunications system is described. In the system and method, a Screening for International Calls database is added to the Integrated Services Network (ISN) platform. The records in the Screening for International Calls database are keyed by the country code and contain a field for blocked terminating regions. When an international call is made, the record corresponding to the international origin point is retrieved from the Screening for International Calls database. This record is checked to determine if there are terminating regions indicated in the blocked exchange field. If there are no terminating regions indicated in the blocked exchange field, call processing continues. If there are terminating regions indicated in the blocked exchange field, the terminating regions in the blocked exchange field are checked against the terminating point of the call.

A method and device for suppressing threshold alerts in a telecommunication fraud control system is disclosed. Threshold alerts are generated when the count of a certain category of call exceeds a certain threshold. These counts are maintained in relation to particular accounts. A fraud analyst determines whether or not a particular account will have alert suppression enabled, based on the type of account and its history. Once alert suppression is enabled, the count is multiplied by a coefficient before determining whether to issue a threshold alert. If the multiplied count still exceeds the threshold, an alert is generated. If not, no alert is generated.

A system for preventing telecommunications fraud, the system comprising a database, at least one processor and related software, the at least one processor receives and stores numbers representing terminating ANIs in the database that have generated a fraud alert. The stored numbers include at 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 processor receives a dialed terminating ANI representing a subsequently dialed call and checks the database to determine if the dialed terminating ANI matches a stored number. The at least one variable length character matches any corresponding character in the dialed terminating ANI. One variable length character may also match one or more 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.

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. When a call is made using a billing number whose corresponding record has the override flag set, 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 is added to the International City Code Database. The addition of CSET to this database allows particular international city destinations to be blocked from certain origin points.
