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.

 

Key words: wireless cellular networks, admission control, multi-class services
