Patent ID: 8750846

Claim:
A method of controlling an incoming call to an incoming call subscriber terminal by a Mobility Management Entity (MME) of a mobile communication system, the method comprising: receiving, by the MME, the incoming call for the incoming call subscriber terminal from an outgoing call terminal; analyzing, by the MME, a type of the incoming call subscriber terminal to determine whether the incoming call subscriber terminal is a first service incoming call subscriber terminal that requires a call restriction for incoming calls; determining, by the MME, if the incoming call subscriber terminal is the first service incoming call subscriber terminal for which the call restriction is required, whether an outgoing call number of the outgoing call terminal is one of previously registered call-allowed numbers based on a list of call-allowed numbers which are allowed to place an incoming call to the incoming call subscriber terminal; and paging, by the MME, the incoming call subscriber terminal, if the outgoing call number is one of the previously registered call-allowed numbers.
