ABSTRACT:
A call restricting method for a packet switching network, by which acception of a call issued from a call origination terminal is restricted to thereby previously prevent the occurrence of a congestion in the packet switching network, in which the call origination terminal informs an associated packet switching node connected to terminal, of traffic parameters indicative of an application state of trunk lines to be connected between the call origination terminal and a destination terminal, and the packet switching node, when informed of these traffic parameters and the calling data, decides one of the trunk lines to be used according to the calling data, and estimates a line quality of the decided trunk line when a new call origination terminal is also added on the basis of a trunk rate of the decided trunk line, traffic parameters of terminals using the trunk line on a multiplex basis at this time and traffic parameters informed from the new call origination terminal.
