A major technical issue related to supporting multiple classes of service in IMT-2000 is the efficient management of limited channel. The selection of channel access control technique has a significant impact on user QOS, system capacity, and is therefore an important design parameter. In this paper, to achieve the service at resonable QOS level, while utilizing channel resource effectively, some improved methods are proposed by analyzing of the recently released methods.
