Improving Service Utility and Service Delivery in Next Generation Networks

Analysis of Joint Call Admission Control Strategies for Heterogeneous Cellular Networks Olabisi Falowo (University of Cape Town, South Africa); H. Anthony Chan (University of Cape Town, South Africa); “This paper investigates three joint call admission control algorithms (JCAC) for heterogeneous cellular networks. These algorithms are random-selectionbased, service-based, and load-based JCAC algorithms. Our approach is based on decomposing heterogeneous cellular networks into groups of colocated cells. We model the JCAC algorithms as a multi-dimensional Markov chain. For each of the three JCAC algorithms, new call blocking probability and handoff call probability are derived and evaluated. The performances of the three JCAC algorithms are compared and the results are presented.”
