  • Quasi reservation-based communication service process system
    Patent number: 4910766
    Abstract: In a communication system which handles both a demand call, and a reservation call which appoints the start time and the end time of the communication, the reservation call must be connected at the desired time even if the circuits are full of the demand calls. The service process node which has a data base storing the information of the reservation calls, tries to connect the reservation call repetitively until the scheduled end time of the reservation call in every predetermined pause, if the circuits are full of the demand calls. Also, when it is anticipated that the circuits would be full at the desired time, the service process node suggests to the subscriber the alternative time for reservation.
