An adaptive bandwidth allocation scheme with preemptive priority for integrated voice/data mobile networks

This paper presents an adaptive bandwidth allocation scheme, called complete sharing with preemptive priority (CSPP) scheme, for integrated voice/data mobile networks. It uses the complete sharing approach to maximize the bandwidth utilization efficiency by allowing data traffic to share all the bandwidth resource of a cell and introduces a preemptive priority mechanism to maintain the high performance of voice traffic while the injury of data traffic is compensated through a victim buffer. A degradation/compensation mechanism is applied to the data traffic which has elastic characteristics. The model of the CSPP scheme is analyzed by a two dimensional Markov process. The steady state probability vector is obtained recursively by the matrix-analytic method and many important performance measures are then determined such as different types of probabilities, total channel utilization, transmission delay, busy period time and blocking period time. From the performance analysis and comparison as well as the numerical results, we can conclude that the CSPP scheme can achieve complete service differentiation for different traffic classes and very high and stable channel utilization under various traffic loads. By adjusting the defined constraint factors, we can not only maintain higher priority for handoff voice over new voice calls and voice calls over data calls but also provide necessary protection for data calls in hot-spot data traffic situations
