| 摘 要： | 为满足下一代网络接入业务多样化的需求,提出了一种基于蜂窝网上行的多业务智能接纳(ICAC)方法.该方法通过统计语音业务的业务量,对下一时间段进行业务预测并分配相应的接入资源;对于数据业务,运用模糊逻辑对用户分配带宽资源.仿真结果表明,对于动态变化的业务流,该方法可有效降低语音业务掉话率和呼损率,减少数据业务接入的等待时延.

| Abstract: | For satisfying the diverse needs of next-generation networks to access multi-class services,an intelligence call admission control(ICAC) algorithm for uplink multi-class services based on cell systems was proposed.The traffic load is estimated through the traffic statistics and the bandwidth is allocated for the next period by this method;for date services,fuzzy logic is used by this method to allocate bandwidth to date traffic;simulation results show that for dynamical traffic load,the method has better performance in reducing call drop rate and block rate of voice traffic,and decreasing accessing waiting time of date traffic. |
