Under this situation, we can use call admission control(CAC) to provide better QoS for real-time traffic by prioritizing different type of service. Traditional CAC schemes only prioritize the priority between new call and handoff call and reserve fixed amount of bandwidth for high priority traffic. It is not suitable for the present network environment which contains several kinds of service. On the other hand, reserving fixed amount of bandwidth will result in worse usage of basestation(BS) bandwidth. Thus, we propose a CAC scheme which incorporates multiple traffic types and adjusts the admission threshold dynamically using fuzzy inference system(FIS) to achieve better usage of BS resource.
