提出了在无线移动网中基于队列的降质接纳控制算法,它区分了实时业务和非实时业务,同时考虑了切换优先和业务优先两种优先级.在网络带宽资源不足时,通过降低某些可容忍质量下降的呼叫的质量并与队列缓存呼叫相结合的方式,来获得小区中高优先级业务的新呼叫阻塞率和切换呼叫中断率均很低的性能改善.性能分析结果显示该算法简单易实现,具有较低的新呼叫阻塞率、切换呼叫中断率和较高的系统利用率.
提齣瞭在無線移動網中基于隊列的降質接納控製算法,它區分瞭實時業務和非實時業務,同時攷慮瞭切換優先和業務優先兩種優先級.在網絡帶寬資源不足時,通過降低某些可容忍質量下降的呼叫的質量併與隊列緩存呼叫相結閤的方式,來穫得小區中高優先級業務的新呼叫阻塞率和切換呼叫中斷率均很低的性能改善.性能分析結果顯示該算法簡單易實現,具有較低的新呼叫阻塞率、切換呼叫中斷率和較高的繫統利用率.

An admission control algorithm based on queues quality degradation in wireless mobile network is proposed.The algorithm distinguishes real-time traffic and non-real-time traffic considering handoff priority and traffic priority.The handoff call dropping probability (CDP) and the new Call Blocking Probability (CBP) are reduced by using quality degradation and queues. Simulation result shows the algorithm can lower new call blocking probability,handoff call dropping probability and improve system utilization ratio(SUR).
