Channel De-allocation for Packets in Integrated Voice/Data Wireless Communication Networks

In this paper, a new de-allocation scheme which the de-allocation channels can be used by both voice calls and packet calls is proposed. To research the possible neglect effect on voice calls for the de-allocated channels can be allocated to the new packets, a threshold of a new packet call can obtain a de-allocation channel or not is proposed and studied. The simulation results show that the new scheme can achieve excellent performance and it is really necessary to let the new packets use the de-allocated channels, when the threshold thetas=2/3 of our scheme in this paper, the blocking probability of voice calls and the mean packet transmission time have nearly no degradation, while the blocking probability of packet calls is decreased evidently and the mean channel utilization is improved significantly.
