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
