Domestic origination to international termination country set logic

A method for preventing fraud on a special service call to an international destination in a telecommunications system, said telecommunications system having customer accounts for billing customers for usage of said system, and having a Billing Number Screening (BNS) database, comprising the steps of:

• a) determining if one or more labels are in a label field of a record of an access code in an access-level database, said access code having been used in the special service call to the international destination;
• b) storing said one or more labels as access-level stored labels if it is determined that the one or more labels are in the label field of the access-level database;
• c) determining if an override flag is set in a record of a billing number in the BNS database, said billing number corresponding to overriding a customer account used to make the special service call to the international destination;
• d) deleting any stored access-level stored labels and jumping to step (h), if the override flag is set in step (c);
• e) determining if one or more labels are in a label field of a record of an exchange in an exchange-level database, said exchange being an origination of the special service call to the international destination;
• f) storing said one or more labels as exchange-level stored labels if it is determined that the one or more labels are in the label field of the exchange-level database;
• g) replacing the one or more access-level stored labels with the one or more exchange-level stored labels, if both exist;
• h) determining if one or more labels are in a label field of a record of an ANI in the ANI-level database, said ANI being an originating ANI of the special service call to the international destination;
• i) storing said one or more labels as ANI-level stored labels if it is determined that the one or more labels are in the label field of the ANI-level database;
• j) replacing any of the one or more access-level stored labels and one or more exchange-level stored labels, if any exist, with the one or more ANI-level stored labels;
• k) determining if one or more stored labels match one or more labels in a label field of a record in an international database, said international database having records keyed to international points, said record corresponding to the international destination of the special service call and matches the labels stored;
• and
• l) blocking the call if it is determined that there is a match in step (k).

A device for preventing fraud in a call to an international destination in a long distance telecommunications system, said telecommunications system connected both internationally and domestically, comprising:

• an international database for maintaining at least one record, each record associated with an international destination, each record having a label field;
• means for determining if one or more stored labels match one or more labels in the label field of a record, when said record is accessed during call processing of said call, the international destination of said call being associated with said record;
• and
• means for blocking the call if the determining means determines that there is a match, wherein the call is a special service call, and there is a label field in various call processing databases, including an access-level database containing records keyed to at least one access code used in obtaining the special service, an exchange-level database, containing records keyed to at least one telephone exchange, and an Automatic Number Identifier (ANI)-level database, containing records keyed ANI;
• means for determining if one or more labels are in the label field of a record of an access code in the access-level database, said access code having been used in the special service call to the international destination;
• means for storing said one or more labels as access-level stored labels if it is determined the one or more labels are in the label field of the access-level database;
• means for determining if one or more labels are in the label field of a record of an exchange in the exchange-level database, said exchange being an origination of the special service call to the international destination;
• means for storing said one or more labels as exchange-level stored labels if it is determined the one or more labels are in the label field of the exchange-level database;
• means for replacing the one or more access-level stored labels with the one or more exchange-level stored labels, if both exist;
• means for determining if one or more labels are in the label field of a record of an ANI in the ANI-level database, said ANI being an originating ANI of the special service call to the international destination;
• means for storing said one or more labels as ANI-level stored labels if it is determined the one or more labels are in the label field of the ANI-level database;
• and
• means for replacing any of the one or more access-level stored labels and one or more exchange-level stored labels with the one or more ANI-level stored labels, if any exist.

A device for preventing fraud in a call to an international destination in a long distance telecommunications system, said telecommunications having customer accounts for billing customers for usage of said system, said telecommunications system further having a fraud control system for creating fraud control blocks, comprising:

• a billing number database for maintaining at least one billing number record, each billing number record associated with one of said customer accounts, each billing number record having an override flag field;
• a first means for determining if an override flag is set in a billing number record, when said billing number record is accessed during call processing of the call using a customer account associated with said record;
• at least one level database for maintaining at least one level record, each level record associated with the smallest unit on a level in a telecommunication hierarchy, each level record having a label field;
• a second means for determining if one or more labels exist in a level record, said level record corresponding to a particular unit on an originating leg of the call;
• means for storing one or more level record labels as stored labels;
• means for deleting stored labels if it is determined that the override flag is set in the billing number record;
• means for preventing the second determining means from operating if it is determined that the override flag is set in the billing number record;
• an international database for maintaining at least one international record, each international record associated with an international destination, each international record having a label field;
• a third means for determining if one or more stored labels match one or more labels in the label field of an international record, when said international record is accessed during call processing of the call to the international destination with said record;
• and
• means for blocking the call if the third determining means finds a match between the one or more stored labels and the one or more labels in the label field of the international record.
