摘要：
In order to ensure that the interference-limited multimedia CDMA mobile communication systems operate stably and reliably, a call admission control mechanism is implemented, with the goal to effectively, fleetly, and accurately control the number of users in the systems. In this study a fast adaptive call admission control (FACAC) method for WCDMA air interface is going to be introduced making fast, accurate, adaptive threshold, simple and feasible decision about incoming calls. Simulation results verify the correctness of theoretic derivations and show that the drop probability and the grade of service (GoS) for FACAC is lower by above 60% and lower by about 23% than those for conventional CAC schemes respectively (when traffic load is higher in the systems).
