  • The proposed Grade of Service based Call Admission Control (GoS-CAC) algorithm operates a threshold comparison, which integrates many factors that affect the decision accuracy of a CAC scheme such as system traffic loads, Quality of Service (QoS) requirements, channel quality, interference level, system GoS and user handoff, etc. The GoS-CAC algorithm cooperates subtly with a power/data rate adjustment scheme making able fast, accurate, adaptive threshold, simple and feasible decision-making about incoming calls. Simulation results show that the proposed algorithm outperforms traditional CAC schemes about 10%, 50% and above 57% in terms of handoff service blocking probability, system GoS and overall system dropping probability, respectively.
