Abstract :
How to control hand-off dropping rate is a very important quality-of-service (QoS) issue in cellular networks. The current trend in cellular networks of reducing cell size makes this issue more difficult to resolve. A novel CAC scheme based on adaptive threshold control (AT-CAC) is proposed in this paper. AT-CAC can adjust admitting threshold according to hand-off dropping rate and process session requests in different methods, e.g. accepting, rejecting and queuing. It can control hand-off dropping rate effectively and increase system utilization rate at the same time. Numerical results show that AT-CAC meets our design goal and outperforms the static reservation scheme under fluctuation of system load.
