The admission control in wireless networks with WCDMA radio interface admits or blocks new calls depending on a current load situation both in the access cell and in neighboring cells. A new call is rejected if the predicted load exceeds particular thresholds set by the radio network planning. This article presents a method for uplink and downlink blocking probability determination in cellular systems with WCDMA radio interface and finite and infinite source population. In our model, we use the load factor to estimate whether a new call of classy service can be admitted or blocked. The proposed scheme is applicable for cost-effective radio resource management in 3G mobile networks and can be easily applied to network capacity calculations.
