Abstract
A system and method are disclosed that provide for the control, by a third party, of call-related services that are provided to a wireless subscriber. For each mobile station whose calls and other communications are to be controlled, the server interposes itself between the serving Visitor Location Register (VLR) of the mobile station and the subscriber's Home Location Register (HLR). Through a sequence of standardized messages, the server represents itself to the unsuspecting HLR as the mobile station's new serving VLR. The server receives from the subscriber's HLR a first set of subscriber data that comprises data related to call-service permissions. The server then modifies a parameter from the first set, restricting an end-user service to the mobile station. The server then transmits the modified parameter to the serving VLR, which is used to block one or more types of calls that involve the mobile station.
