Description

DESCRIPTION
A SYSTEM FOR DETECTING LONG-TERM CALLS Technical Field
The present invention relates to a system which enables to detect the said call as long-term call in the event that duration of a call made over mobile network is equal to a certain length or longer than this length within pre-determined rules.
Background of the Invention
Today, international revenue sharing fraud-which causes network operators to make loss by being obliged to pay high prices due to swindlers- is generally realized in mobile telecommunication sector. International revenue sharing fraud is usually carried out in the form of multiple and long calls towards a single number. Mobile network operators pay high prices for the said calls which are realized in the form of calls made by international carriers and terminated by charging high prices.
International revenue sharing fraud can be defined as follows in the simplest term: The first condition for international revenue sharing fraud is to arrange subscribers from mobile network operators where the call will be initiated. The said subscribers can be obtained by many different methods for example such as capturing SIM's, PBX systems, stolen lines. Then, the international premium rate number (IPRN) to be called is found out. The said international premium rate number can be obtained by means of international premium rate number providers who are located in a country different from the calling subscriber's country by using international carriers. After the subscribers wherein the call will be initiated and the international premium rate number to be called are obtained, long-term and multiple calls are initiated towards the international premium rate number by using the subscribers who are included in the mobile network operator wherein the calls will be initiated. The fees obtained from the calls received over international carriers by the mobile network operator are shared with the international premium rate number committing fraud by revenue sharing and lastly, it is decided whether to make next calls or not by calculating the fees earned or lost in some cases.
The International patent document no. WO2013030574, an application in the state of the art, discloses a system for detecting forgery and fraud situations within a mobile communication network. The said system comprises components which are configured in order to observe pre-determined types of data within the data being carried over interfaces within mobile communication network. After the observation carried out by these components; many types of forgery/fraud such as gateway forgery/fraud, revenue sharing fraud, credit card fraud can be detected.
Summary of the Invention
An objective of the present invention is to realize a system which enables to detect the said call as long-term call in the event that duration of a call made over mobile network is equal to a certain length or longer than this length within predetermined rules.
Another objective of the present invention is to realize a system which enables to terminate detected long-term calls.
A further objective of the present invention is to realize a system which enables to prevent international revenue sharing fraud. Detailed Description of the Invention
"A System for Detecting Long-Term Calls" realized to fulfill the objectives of the present invention is shown in the figure attached, in which:
Figure 1 is a schematic view of the inventive system.
The components illustrated in the figure are individually numbered, where the numbers refer to the following:
1. System
2. Database
3. Long-term call detection unit
S. Station
The inventive system (1) enabling to detect the said call as long-term call in the event that duration of a call made over mobile network is equal to a certain length or longer than this length within pre-determined rules comprises:
at least one database (2) wherein the rules required for determining a call as long-term are recorded; and
at least one long-term call detection unit (3) which is in communication with the database (2) and the station (S) included within the mobile network operator; receives call detail records related to calls made from the station (S) to the mobile network operator subscribers; and compares the duration of the call being continued in accordance with the said call detail records with the rules recorded in the database (2); and accordingly detects whether the call is long-term or not.
The database (2) included in the inventive system (1) is in communication with the long-term call detection unit (3). Rules required for determining calls which are made to a mobile network operator subscriber as long-term are recorded inside the database (2). In one embodiment of the invention, the rule recorded inside the database (2) is to determine this call as long-term if a call initiated from a certain location such as cell, region or city continues for a period of time longer than a certain period of time. In one embodiment of the invention, the rule recorded inside the database (2) is to determine this call as long-term if a call initiated to a certain called number continues for a period of time longer than a certain period of time. In one embodiment of the invention, the rule recorded inside the database (2) is to determine this call as long-term if a call initiated to the number getting service from a certain mobile network operator continues for a period of time longer than a certain period of time. In one embodiment of the invention, the rule recorded inside the database (2) is to determine this call as long-term if a call continues for a period of time longer than a certain period of time.
The long-term call detection unit (3) included in the inventive system (1) is in communication with the database (2) and the station (S) included within the mobile network operator. The long-term call detection unit (3) receives the call detail records related to calls which are made from the station (S) to the mobile network operator subscribers and continue, and compares the duration of the continuing with the rules recorded in the database (2) from the call information included in the said call detail records. The long-term call detection unit (3) determines the said call as long-term call if the call detail record information received from the station (S) as a result of the comparison transaction match with at least one rule recorded in the database (2). In one embodiment of the invention, the long-term call detection unit (3) sends call termination instruction to the station (S) in order to terminate the call that is detected as long-term. And the station (S) terminates the call determined as long- term by the long-term call detection unit (3) in accordance with the instruction received from the long-term call detection unit (3). Within these basic concepts; it is possible to develop a wide range of embodiments of the inventive "System for Detecting Long-Term Calls (1)", the invention cannot be limited to examples disclosed herein and it is essentially according to claims.
