Due to the fact that Quality of Service (QoS) requirements are not as\nstringent for non-real-time traffic types, as opposed to real-time traffic,\nmore calls can be accommodated by releasing some bandwidth from the existing\nnon-real-time traffic calls. If the released bandwidth to accept a handover\ncall is larger than to accept a new call, then the probability of dropping a\ncall is smaller than the probability of blocking a call. In this paper we\npropose an efficient Call Admission Control (CAC) that relies on adaptive\nmulti-level bandwidth-allocation scheme for non-real-time calls. The features\nof the scheme allow reduction of the call dropping probability along with the\nincrease of the bandwidth utilization. The numerical results show that the\nproposed scheme is able to attain negligible handover call dropping probability\nwithout sacrificing bandwidth utilization.\n
