ABSTRACT:
A system and method in a radio telecommunications network for preventing fraudulent call transfers by selectively restricting or disabling a call transfer immediate (CTR) feature is disclosed. The system includes a database of subscriber information which includes information relating to each subscriber's activated features and transfer-to numbers. The system also includes feature logic connected to the database for performing functions related to the activated features and for denying services related to features tat are not activated. CTR-disable logic is connected to the database and to the feature logic for selectively restricting or disabling the CTR feature when conditions indicative of fraudulent usage are detected. The method restricts or disables the CTR feature if the number of CTR call transfer requests exceeds a threshold number of requests within a predetermined time period. The method may also restrict or disable the CTR feature if the transfer-to telephone number included in the CTR call transfer request is not on a List of approved transfer-to telephone numbers. The CTR-disable logic may also restrict or disable the CTR feature if any two successive transfer requests occur too rapidly.
