SIR-based call admission control by intercell interference prediction for DS-CDMA systems

Abstract

A new signal-to-interference ratio (SIR)-based call admission control (CAC) scheme is proposed in DS-CDMA systems. In this scheme, a new call is accepted by a base station (BS) if the SIR’s at that specific BS and its nearby, not necessarily adjacent, BS’s can be guaranteed to be higher than some threshold value after accepting the new call. The SIR’s of the nearby BS’s can be guaranteed by predicting the additional intercell interferences the new call will produce if it is accepted by the specific BS. Numerical results show that this scheme outperforms previous SIR-based CAC schemes.
