  • Patent number: 8750846
    Abstract: An apparatus and method for controlling an incoming call to an incoming call subscriber terminal of a mobile communication system. A Mobility Management Entity (MME) receives the incoming call for the incoming call subscriber terminal from an outgoing call terminal, analyzes a type of the incoming call subscriber to determine whether a call restriction is required for incoming calls to the incoming call subscriber terminal, determines whether an outgoing call number of the outgoing call terminal is one of previously registered call-allowed numbers, if the call restriction is required; and pages the incoming call subscriber terminal, if the outgoing call number is one of the previously registered call-allowed numbers.
