1. A method for Connection Admission Control (CAC) in a Broadband Wireless Access (BWA) system, the method comprising:

  • detecting a QoS class of a call requesting connection admission;

    determining an application layer required bandwidth by using the QoS parameters of a service flow of the detected QoS class;

    determining a required bandwidth weight of the QoS class in consideration of a packet header overhead;

    determining per-slot available bandwidths of a reference QoS class and the QoS class by using the determined application layer required bandwidth;

    determining a required bandwidth conversion ratio of a corresponding QoS class by using the determined per-slot available bandwidths; and

    determining an equivalent MAC layer required bandwidth by using the determined application layer required bandwidth, the required bandwidth weight, and the required bandwidth conversion ratio.
