A Novel Effective Bandwidth Based Gall Admission Control for Multimedia CDMA Systems

摘要

A novel Call Admission Control (CAC) scheme is proposed for multimedia CDMA systems. The effective bandwidth of real time calls is reserved in the CAC with the consideration of active factors. The admission of non-real time calls is controlled by the system according to the residual effective bandwidth left from real time calls. Simulation results have shown that the novel CAC has greatly enlarged the admission region for real time calls and make the transmission delay of non-real time calls under an acceptable level.
