摘要：
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.
