【摘要】 本文对一种新的基于实测的呼叫接入控制算法进行了仿真分析。研究结果表明预测算法均方差很小,同时不同多媒体业务的切换阻塞率和在总允许接入呼叫数中所占比例,在业务负载低于系统容量时满足要求;而在高负载情况下,性能出现分化,其中高带宽业务的服务质量下降更快。更多还原

【Abstract】 A novel measurement-based call admission algorithm for wireless mobile networks utilizing time series analysis is put forward in this paper. And the handoff-dropping probabilities and the proportions in the admitted sessions of every service types are comparatively studied through simulations, which results indicate that performances of different types can maintain good enough until the total traffic load below the system capacity. Otherwise, the quality-of-service (QoS) with higher bandwidth request will drop much more quickly.更多还原
