Filed: 1987-02-20
Abstract: PURPOSE:To reduce the call loss and the delay of a priority call and to improve efficiency in preferentially processing the priority call by managing in order to limit the process of posteriority call every time zone. CONSTITUTION:The titled system is provided a comparison means 29, a posteriority call process means 31 and a holding control means 33. The means 29 is what reads out the number of the posteriority calls which can be simultaneously processed in the detected time zone from a process-enabled call number storage means 23 and compares the number of the read posteriority calls with that of the posteriority calls in the midst of processing. The means 31 is what processes the posteriority calls when the number of the read posteriority calls which can be simultaneously processed is larger than that of the posteriority calls in the midst of processing based on the compared result. And the means 33 is what makes the posteriority calls held until the process is possible when the number of the read posteriority calls which can be simultaneously processed is as same as that of the posteriority calls in the midst of processing. Thus it is reduced that the internal resource and the lines for outgoing call in a communication processing device are used needlessly by the posteriority calls, so that services for the priority call can be improved and moreover the processing ability of the whole system can be improved.
