Preemption is a possible way to ensure emergency traffic's priority in wireless network. But a pure preemption policy can be especially harsh to low priority calls. A way to improve this is introducing a queuing mechanism, which means putting preempted calls into a queue so that they can resume when channels become available, as long as they do not give up due to waiting too long in the queue. Also, we bring out a single preemption scheme, to avoid calls being preempted multiple times. The analytical results for performance analysis of these methods are given, and based on them the performance of different schemes are evaluated and compared
