Call admission control for real time multimedia services with variable bit rate (VBR) is considered in this paper. In the WCDMA system, one of the most prevailing services will be real time multimedia in which the data rate changes dynamically. In this paper, we propose two call admission schemes that effectively reflect features of VBR multimedia services and well satisfy the objectives. The proposed schemes are based on the signal to interference ratio (SIR) of the system. Especially, they anticipate the fluctuation of SIR due to the data rate change of each multimedia service and make an admission decision based on prediction of future SIR rather than the current SIR value. The proposed schemes are compared with an admission policy whose admission decision depends only on the current SIR value.
