Abstract
A call setup control apparatus has a first calculation unit for calculating an objective value of cell loss ratio P,(u) of a buffer B,in priority class u which is equal to or lower than a priority class k (u=k to K), based upon parameters of an average cell rate R(k,j), an objective value of cell loss ratio Q(k,j), and the number of calls N(k,j) for calls of each type j (J=1 to J,) in each class k (=1 to K), with considering a cell rate of calls in priority class which is higher than the class k (class 1 to k−1), when a fresh call is arrived, a unit for obtaining a bandwidth &agr;(k,u,j) required for calls of type j in class k in the buffer B,to make a cell loss ratio in the buffer B,to be equal to or less than the objective value P,(u), a second calculation unit for calculating a required bandwidth C(u) for the buffer B,, based upon the obtained bandwidth &agr;(k,u,j), and a unit for judging whether the fresh call is acceptable or not by comparing the calculated bandwidth C(u) with a link capacity C,.
