摘要：Call admission control (CAC) is a radio resource management technique aimed at providing fair qualityof service (QoS) and grade of service (GoS) to mobile users in cellular networks. GoS refers the probability of blockinga new call request while QoS refers to the probability of loss of communication quality. This work presents anoverview of the various techniques adopted for CAC bearing in mind core issues in cellular networks like coverage,capacity, throughput, diverse QoS requirements of mobile users, and blocking probability. We make effort, realizingthese few issues, to comparatively analyze the performance of these schemes in order to highlight their suitability for ahomogenous/heterogeneous traffic class, single/multi-cell environment in the uplink direction of a cellular CDMAnetwork.
