In order to provide an adaptive control band management method that equally guarantees the call blocking rate of each traffic to a predetermined level or less, call blocking by traffic is calculated to obtain the largest call blocking rate (Bmax) and the smallest call blocking rate (Bmin). A first step (31 to 34) for determining whether the difference of?) Exceeds a predetermined first reference value (a); A second step (35) of reallocating and terminating the band when the difference between the two values exceeds the predetermined first reference value (a); If the difference between the two values is less than or equal to the first predetermined reference value (a), it is determined whether a difference between the two values exists between the first and second reference values (a) and the second reference value (b). If it exists between the predetermined first reference value (a) and the predetermined second reference value (b), the band is reallocated and terminated, and the difference between the two values is the predetermined first reference value (a) and the predetermined second reference value ( b) a third step (36,37) which terminates immediately if there is no presence between them ensures the call blocking rate for each traffic type evenly below the appropriate level, while accommodating as much traffic as possible to maximize the bandwidth utilization of the network. It is effective to utilize resources efficiently.
