Performance evaluation of novel call admission control schemes for femtocell networks through adjustion QoS

Indoor mobile users often suffer from poor connectivity, Femtocell technology is a promising solution for this connectivity, It has rapidly developed and deployed to meet the demand of the huge increasing wireless capacity for the future wireless communications is The femtocellular network. In this paper, we propose new hybrid access methods, our methods lead to increase the performance of the femtocell. The proposed method is based on mixing two ideas. First one is hybrid access method with control over QoS. Second one is accepting nonsubscriber user with probability.
