ABSTRACT:
A system and method in a radio telecommunications network having a home location register (HLR) and a serving mobile switching center (MSC) of preventing fraudulent long distance calls from a subscriber's mobile station by selectively barring the mobile station from accessing the network when an indication of fraud exists. The system sends from the serving MSC to the HLR, an indication of a long distance call origination from the subscriber's mobile station, starts a timer, increments a counter which counts long distance call originations, and determines whether the number of long distance call originations exceeds a predetermined threshold. The system allows the long distance call upon determining that the number of long distance call originations does not exceed the predetermined threshold. The system further determines whether a time period threshold has been exceeded, upon determining that the number of long distance call originations exceeds the predetermined threshold. The long distance call is allowed upon determining that the time period threshold has been exceeded. The call is disconnected, and the mobile station is barred from accessing the network upon determining that the time period threshold has not been exceeded.
