The development of efficient Call Admission Control schemes for next generation wireless cellular networks remains a challenging and yet unresolved problem, due to the rapidly growing number of multimedia applications and to user mobility. In recent work we have modeled the behavior of H.263 videoconference traces with the use of a Discrete Autoregressive (DAR(1)) model. Based on this model, we then proposed an efficient CAC scheme for videoconference traffic over cellular networks, which uses precomputed traffic scenarios for its decision-making and which was shown to clearly excel in comparison with well-known existing approaches, in terms of Quality of Service (QoS) provisioning to users receiving videoconference traffic. In this paper, we continue our work by enhancing and further studying our scheme for the case of “unknown users” attempting to enter the network and for the case of providing call admission control to web users as well as videoconference ones.
