Abstract :
In this paper, we propose an adaptive call admission control scheme based on higher order Markov chains to effectively handle the call blocking probability in 3GPP LTE femtocell networks supporting multimedia services with different classes of traffic and diverse bandwidth requirements. The accuracy of the approximate analytic model is validated by simulation analysis. The numerical results show that the proposed scheme is able to attain negligible call blocking probability without sacrificing resource utilization
