Description

Technology area

The present invention relates to a system and method for preventing mobile operators from paying high amounts by blocking fraudulent distribution of income between operators of different countries.

Background of the invention

Currently, IRSF, which causes network operators to suffer losses due to large sums of money due to fraudulent activities, is commonly carried out in the mobile industry. Fraud of income distribution between operators of different countries is usually carried out in the form of multiple and long-term calls to one number. Mobile operators pay high fees for these calls, which are in the form of calls made by international operators and result in high fees.

The fraud of distribution of income between operators of different countries can be defined as follows in the most simplified form.

The first condition for performing a fraudulent distribution of income between operators of different countries is to find subscribers from mobile operators to whose numbers the call will be initiated. This action can be performed in many different ways, for example, such as SIM hijacking, PBX systems, stolen lines. Then, the international premium rate call (IPRN) number to be called is found. The specified number with international premium rate service can be obtained through international premium rate service providers located in a country other than the country of the calling subscriber using international operators. After finding the subscribers to whose numbers the call will be initiated, and the numbers with the international premium rate service to be called, initiate long and repeated calls to the number with the international premium rate service using the subscriber numbers belonging to the mobile operator. connections to which calls will be initiated. The amounts charged for calls received through international operators by the mobile operator are split with the number with the international premium call service number, which makes fraud through revenue sharing, and ultimately a decision is made whether to make the next calls or not by calculating the amount earned or spent in some cases.

International patent document WO 2013030574, a prior art application, describes a system for detecting counterfeiting and fraud situations in a mobile communication network. The specified system contains components made with the possibility of fixing predetermined types of data in the data transmitted over the interfaces in the mobile communication network. Once committed by these components, many types of counterfeit / fraud can be detected, such as gateway counterfeit / fraud, operator revenue sharing fraud, credit card fraud.

The system (1) for preventing fraudulent distribution of income between operators of different countries according to the present invention contains at least one database (2) of data in which numbers with the international service of payment of a call at an increased rate (IPRN), previously defined and used in the distribution fraud, are recorded income between operators of different countries;

at least one block (3) for preventing fraud, which is in contact with the base (2)

- 1,037309 data and a station (S) belonging to a mobile operator; moreover, when a subscriber of a mobile operator needs to make a call abroad, the unit connects to the database (2) by receiving the specified call from the station (S) and checks whether the number from which you want to make a call abroad and the number with which the call to be made abroad will be set to the database (2) or not; if it receives information, as a result of a verification transaction, that the number from which it is required to make a call abroad, and the number with which the call that needs to be made abroad will be established are recorded in the database (2) of the data, it sends a command to the station (S) with the prohibition of call setup; if it receives information as a result of a verification transaction that the number from which it is required to make a call abroad, and the number with which the call that needs to be made abroad will be established are not recorded in the database (2), it checks, whether the number from which you want to make a call abroad has a current call or not by contacting the station (S); if he determines as a result of a verification transaction that the number from which it is required to make a call abroad does not have a current call, he is inactive; if it determines as a result of the verification transaction that the number from which it is required to make a call abroad has a current call, it checks whether a certain current call and a call that needs to be made abroad are made to the same number or not; if he determines as a result of a verification transaction that a certain current call and a call that needs to be made abroad is required to be made to different numbers, he is inactive; if he determines, as a result of a verification transaction, that a certain current call and a call that needs to be made abroad, needs to be made to the same numbers, he sends a command to station (S), terminating the current call and barring the establishment of the call that needs to be made abroad; and writes the specified number to the database (2) data by connecting to the database (2) data.

The database (2) belonging to the system (1) according to the present invention is in communication with the block (3) for preventing fraud, and it contains numbers with the international service call payment at an increased tariff, previously defined and used in the fraud of income distribution between operators different countries.

The fraud prevention unit (3) belonging to the system (1) according to the present invention is in communication with the data base (2) and the station (S), which belongs to the mobile operator, and makes it possible to establish calls requested by subscribers by receiving requests to establish a call from subscribers of a mobile operator. The fraud prevention unit (3) receives the specified call from the station (S) when the subscriber of the mobile operator needs to make a call abroad. In one preferred embodiment of the present invention, the call is routed from station (S) to CAMEL SS7 fraud prevention unit (3). The fraud prevention unit (3) connects to the database (2) after receiving the call directed from the station (S) and checks whether the number from which you want to make a call abroad and the number with which the call will be established is recorded. commit abroad, to the database (2) or not. If the block (3) for preventing fraud receives information, as a result of a verification transaction, that the number from which it is required to make a call abroad and the number with which the call that needs to be made abroad will be established are recorded in the database (2 ) data, the fraud prevention unit (3) sends a command to the station (S) with a call setup barring. If the block (3) for preventing fraud receives information as a result of a verification transaction that the number from which it is required to make a call abroad, and the number with which the call that needs to be made abroad will be established are not recorded in the database (2) data, the block (3) fraud prevention checks whether the number from which you want to make a call abroad, the current call or not by contacting the station (S). If the fraud prevention unit (3) determines, as a result of a verification transaction, that the number from which a call abroad is required does not have a current call, the fraud prevention unit (3) is inactive. If the fraud prevention unit (3) determines, as a result of a verification transaction, that the number from which an outbound call is to be made has a current call, the fraud prevention unit (3) checks whether a certain current call is being made and a call that needs to be made abroad, to the same number or not. If the fraud prevention unit (3) determines, as a result of a verification transaction, that a certain current call and a call to be made abroad are required to be made to different numbers, the fraud prevention unit (3) is inactive. If the fraud prevention unit (3) determines, as a result of a verification transaction, that a certain current call and a call that needs to be made abroad are required to be made to the same numbers, the fraud prevention unit (3) sends a command to station (S) with terminating the current call and barring the establishment of a call that needs to be made abroad. Block (3) fraud prevention also writes the number from which you want to make a call abroad, in the database (2) by connecting to the database (2) data.

The method (100) for preventing fraud of distribution of income between operators of different countries according to the present invention includes the following steps:

receiving a call to be made abroad from station (S) (101);

checking whether the number from which you want to make a call abroad, and the number from which the call that you want to make abroad will be set is recorded in the database (2) or not (102);

sending a command to the station (S) with call establishment barring (103), if, as a result of the verification transaction (102), it is determined that the number from which a call is to be made abroad and the number with which the call to be made abroad will be established , recorded in the database (2) data; checking whether the number from which you want to make a call abroad has a current call or not (104), if, as a result of the verification transaction (102), it is determined that the number from which you want to make a call abroad, and the number with which it will be a call is set that needs to be made abroad, are not recorded in the database (2) data;

inaction (108) if, as a result of the verification transaction (104), it is determined that the number from which you want to make a call abroad does not have a current call;

checking whether a certain current call and a call to be made abroad are made to the same number or not (105), if, as a result of a verification transaction (104), it is determined that the number from which you want to make a call abroad, has an ongoing call;

inaction (108) if, as a result of the verification transaction (105), it is determined that a certain current call and a call that needs to be made abroad is required to be made to different numbers;

sending a command to the station (S) with the termination of the current call and the prohibition of the establishment of a call that needs to be made abroad (106), if, as a result of a verification transaction (105), it is determined that a certain current call and a call that needs to be made abroad is required to be made to the same numbers;

recording the number from which you want to make a call abroad to the database (2) by connecting to the database (2) data.

In the method (100) for preventing fraud of distribution of income between operators of different countries, the block (3) for preventing fraud receives the specified call from the station (S) when the subscriber of the mobile operator needs to make a call abroad (101). In one preferred embodiment of the present invention, the call is routed from station (S) to CAMEL SS7 fraud prevention unit (3).
