PURPOSE:To prevent the occurrence of an abnormal traffic by receiving a date time designation call when a traffic after the present point of time is lower than a threshold value set to a lower value than the specified value and receiving an instant call when the total traffic of the instant call and the date/time designation call is lower than the specified value. CONSTITUTION:A threshold value regulating a reservation call such as date/time designation or the like is selected to be a value smaller than the specified value regulating the reception of an instant call to make the communication of the instant call excellent. The instant call such as multiple address communication or a general call is sent soon when it is received by a communication processor. Since the date/time is designated from a reservation call such as date/time communication is subject to date/time designation, the call is stored in the communication processor Thus, when the reservation call is limited by a specified value, the traffic reaches the limit before the designated date/time comes and the communication of the instant call occurred near the designated date/time is not attained. Thus, the reserved call is regulated by a threshold value smaller than the specified value.
