Abstract

PURPOSE:To reject the arrival of an incoming call such as an annogance call by rejecting the arrival of a call upon receipt of a call setup message not including a caller number and rejecting the call when the time of the arrival of the call is within a registration time of incoming call reject. CONSTITUTION:A communication terminal equipment A3 sends a call setup message 5b to establish a call to a communication terminal equipment B4 and the terminal equipment B4 receives a call setup message 5c sent by the terminal equipment B4 to inform that a communication network 1 has a request to establish a call from the terminal equipment A3 to the terminal equipment B4. Whether or not a caller number is included in a message 5c is checked by using a detection means 661 in a control section 66. When included, a registration means 664 and an incoming call check means 663 are used and when the incoming time is within an incoming call reject time zone, a control section 61 sends a release end message 6a to the communication network 1 to reject a call. On the other hand, the incoming call is rejected to the message 5c not including the caller number.
