Abstract

Adaptive traffic control apparatus and method control connection of arriving calls in at least one circuit group in circuit-switched networks. The switching systems in general measure the number of calls in progress n(t) at a time t in the circuit group, where t.sub.0 .ltoreq.t.ltoreq.T, t.sub.0 is a traffic control initiation time and T is a target time of the traffic control. In particular, an admissible number of calls d(t) in the circuit group at the time tis calculated so that all the circuits of the group will be free by the target time T, and the measured number of calls in progress n(t) is compared with the calculated admissible number of call d(t) at each time a new call arrives at the circuit group to decide that the arriving new call is to be accepted if n(t)
