摘要: In this paper, we propose a new call admission control scheme called dual threshold bandwidth reservation, or DTBR scheme. The main novelty is that it builds upon complete sharing approach, in which the channels each cell are shared among different traffic types and multiple thresholds used to meet specific quality-of-service (QoS) requirements. We present detailed comparative study based on mathematical simulation models, quantitatively demonstrate capable of providing QoS guarantee for type traffic, while at same time leading much better channel efficiency. further show with elastic data service can offer both differentiation voice services, enhance utilization.
