Abstract: PURPOSE: A method for denying selective forwarding of a mobile communication terminal is provided to interrupt a telephone call with the other party registered to deny forwarding. CONSTITUTION: If a call to a predetermined subscriber is originated, an exchanger requests an HLR(Home Location Register) to confirm "Do Not Disturb" function registration state to the corresponding subscriber(910). The HLR reports the search result of "Do Not Disturb" function list related to the corresponding subscriber(920). The exchanger transmits a call connect impossible message to an originating terminal if the exchanger judges that selective "Do Not Disturb" function to the subscriber is settled(940). The exchanger releases the call of the originating terminal(950).
