The AAA divided a cell into several areas. Variations in the traffic loads among areas will lessen the traffic-carrying capacity. Moreover, the handoff procedure usually takes place when the call crosses the area boundary. A larger number of areas will increase the system overhead for handling the handoff procedure. An ineffective management will increase the system overheads, such as spreading code switch, data switch, and even network switch. In this thesis, we propose an effective load balance and handoff management strategy. This strategy is implemented to solve traffic-adaptation problem that can enhance the traffic-carrying capacity for variations in traffic. For the management of handoff procedure, our strategy considers the mobility of mobile hosts and the bandwidth utilization. It can decrease the number of handoff procedures and lessen the system overhead. Furthermore, the simulation results are presented to confirm the efficiency of the proposed strategy.
