Abstract

The proposed Grade of Service based Call Admission Control (GoS-CAC) algorithm in the next generation mobile communications system 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 control and data rate adjustment scheme making able fast, accurate, adaptive threshold, simple and feasible decision-making about incoming calls for next generation mobile communications systems. Simulation results show that the proposed algorithm outperforms SIR based CAC (SIR-CAC) and interference based CAC (I-CAC) schemes about 10%, 50% and above 57% in terms of handoff service blocking probability, system GoS and overall system dropping probability, respectively.
