Abstract
Radio Resource Management (RRM) techniques are used in wireless broadband networks to improve the utilization of network resources and guaranteeing the Quality of Service (QoS) of different users. Call Admission Control (CAC) is one of such techniques that has the responsibility of deciding which call connection to be accepted or rejected by the network. CAC has been in existing since during the 2G network era and several schemes have been proposed by different researchers. This paper gives an overview of how CAC procedure works in 2G, 3G, 4G and 5G networks. Basic Call Admission Control scheme (BCAC), Multi-Service Call Admission Control (MS-CAC) and Enhanced Adaptive Call Admission control (EA-CAC) schemes were discussed as the schemes proposed for 2G, 3G and 4G networks respectively. Finally, the paper discusses the CAC procedure for 5G networks by explaining all the steps involved for a CAC scheme’s decision taking
