“…Instead, there has been a heavy reliance on simulation to tackle this problem. Such simulations [2] are time consuming, and don't lend themselves to quick estimates of blocking rate, nor provide insight into the performance of capacity-enhancement algorithms [3,4]. The universal adoption of CDMA as the access method for 3rd generation wireless systems, and the expectation that the forward link will dominate the system traffic, has exacerbated the need for such a model.…”

The use of simple models based on queuing theory for the prediction of call blocking, has a long history in telephony. Formulas such as Erlang B, Erlang C, and others have been applied successfully to wireless as well as wireline systems. A simple model for the soft blocking criteria employed in CDMA systems, particularly those based on forward link power, is however lacking. Such a model must take into account the statistics of the forward link power, as well as the characteristics of the traffic. The need for such a model is exacerbated by the adoption of CDMA as the access technology for various 3rd generation wireless systems. This paper presents a simple model for forward link power-based blocking in CDMA systems. The accuracy of the model is indicated by comparing its predictions against the results obtained from a fully dynamic CDMA system simulator.

Universal mobile telecommunications system (UMTS) is one of the 3 rd generation (3G) cell phone technologies. The capacity of UMTS is interference limited. Radio resources management (RRM) functions are therefore used. They are responsible for supplying optimum coverage, ensuring efficient use of physical resources, and providing the maximum planned capacity. This paper deals with admission control techniques for UMTS system. A UMTS system model and several versions of admission control algorithms are presented in this paper. These algorithms are based on fuzzy logic and they use simple user movement prediction methods. The algorithms are mutually compared via simulations.
