Abstract

Bu buluş, bir telekomünikasyon OŞ (10) (Operatör Şebekesi)?ndeki arabağlantı dolandırıcılığının önlenmesi için bir yöntem ve sistem ile ilgili olup söz konusu yöntem ve sistem hem gerçek abonelerin gerçek çağrılarının hem de test çağrılarının gerçek abone numaralarına doğru yaptığı aramaları kullanır. Söz konusu buluşta gerçek veya test çağrılarının AAN (Aranan Abone Numarası)?ları bir KB (11) (Kontrol Birimi) tarafından kontrol edilirler. Uluslararası Arabağlantıdan ANB (Arayan Numara Bilgisi) Dolandırıcılığı, Ulusal Arabağlantıdan ANB Dolandırıcılığı, Şebekede Doğan Dolandırıcılık ve Şebekede Sonlanan Dolandırıcılık, AAN?nın sonlanan çağrılarına ilişkin GYKK (Gelinen Yolun Kaynak Kodu)?ları analiz edilerek tespit edilip önlenir. Uluslararası Arabağlantıdan ANB Dolandırıcılığında, dolandırıcılar arayan numara bilgisi veya arayan taraf numaralarını manipüle etmek suretiyle uluslararası çağrıları daha düşük sonlandırma ücretiyle sonlandırırlar. Ulusal Arabağlantıdan ANB Dolandırıcılığında, dolandırıcılar uluslararası çağrıları ulusal arabağlantı yollarından sonlandırırlar. Şebekede Doğan Dolandırıcılıkta, DB (30) (Dolandırıcı Birimi)?leri OŞ (10)?nden uluslararası yabancı numaralara doğru doğan uluslararası çağrılar yaparlar ki bu çağrılar OŞ (10)?nin uzak mesafe arama tarifelerini istismar etmektedir. Bu DB (30)?leri transit uluslararası çağrıları OŞ (10)?nden giden uluslararası çağrılar olarak taşırlar. Şebekede Sonlanan Dolandırıcılıkta, bu DB (30)?leri uluslararası çağrıları sonlandırmak üzere OŞ (10)?nin abonelerine doğru doğan ulusal çağrılar yaparlar. Şebekede Doğan Dolandırıcılıkta ve Şebekede Sonlanan Dolandırıcılıkta, DB (30)?leri tarafından istismar edilen ?SIM Box? gibi abonelik numaraları engellenir.The present invention relates to a method and system for preventing interconnection fraud in a telecommunications OŞ (10) (Operator Network), which method and system use both real calls of real subscribers and calls made by test calls to real subscriber numbers. In the invention in question, AAN (Called Subscriber Number) of real or test calls are controlled by a KB (11) (Control Unit). ANB (Caller Number Information) Fraud from International Interconnection, ANB Fraud from National Interconnection, Network Originated Fraud and Network Terminated Fraud are detected and prevented by analyzing the GYKK (Source Code of the Way Reached) for AAN's terminated calls. In International Interconnection ANB Scam, scammers manipulate caller number information or caller numbers to terminate international calls with lower termination rates. In National Interconnection ANB Scam, scammers terminate international calls on national interconnection routes. In Network Scam, DB (30) (Scam Units) make international calls from OŞ (10) to international foreign numbers, which are exploiting OŞ (10)'s long distance calling rates. These DBs (30) carry transit international calls as outbound international calls from OŞ (10). In Network Terminated Scam, these DBs (30) make national calls to OŞ (10)'s subscribers to terminate international calls. In Network Born Fraud and Network Terminated Fraud, the ?SIM Box? subscription numbers such as
