摘要

Next generation wireless communication systems are expected to satisfy quality of service (QoS) requirements by preventing call droppings which are caused by user mobility. Call admission control (CAC) is becoming more important in guaranteeing the QoS of calls. Since existing CAC schemes estimate future requirements and reserve bandwidth to guarantee a certain level of QoS, the bandwidth estimation method is very important in CAC schemes. Most conventional schemes use the movement information of individual mobile terminals (MTs) to estimate the bandwidth requirements. While these schemes estimate the future bandwidth usage relatively well, it requires high computational overhead and lots of memory space to keep and update the movement information of each mobile terminal, and therefore is hard to implement. In this study, we propose a call admission control scheme, which estimates the future handoffs using the handoff histories between BSs and the MT conformity. The proposed scheme achieves low dropping ratio and high bandwidth utilization keeping low computational overhead. The performance of the proposed scheme is evaluated through simulations.
