Search for: [Description = "In this paper, a multirate loss model for the calculation of time and call congestion probabilities in a Wideband Code Division Multiple Access \(W\-CDMA\) cell is considered. It utilizes the Bandwidth Reservation \(BR\) policy and supports calls generated by an innite or nite number of users. The BR policy achieves QoS equalization by equalizing congestion probabilities among calls of dierent service\-classes. In the proposed models a multiple access interference is considered, and the notion of local blocking, user's activity and interference cancelation. Although the analysis of the proposed models reveals that the steady state probabilities do not have a product form solution, the authors show that the calculation of time and call congestion probabilities can be based on approximate but recursive formulas, whose accuracy is veried through simulation and found to be quite satisfactory."]
