Abstract :
We propose a preemptive priority handoff scheme for integrated voice/data cellular mobile systems. In our scheme, calls are divided into three different classes: handoff voice calls, originating voice calls, and data calls. In each cell of the system there is a queue only for data calls. The right to preempt the service of data is given to a handoff voice call if on arrival it finds no idle channels. The results are compared with another handoff scheme. It is shown that, when the data traffic is not very light, our scheme can provide better quality of service (QOS) to mobile users
