Abstract

In this study, for providing quality of service, call admission control shemes, one of the most important methods in efficient radio resource management techniques, have been reviewed. Next generation wireless Networks (3G, 4G) will be support more users and multimedia services. With increasing user number and multimedia service needs, for using limited resources in a efficient way, it is needed efficient radio resource management, differrent call admission schemes and evaluation of these schemes with Markov Chain model has been explained for this requirements.
