The problem of handoff calls management in cellular mobile communication is discussed. A simple but efficient design of a cellular network for a small area is proposed so as to keep blocking probability of handoff calls (BH) below a pre-defined margin. The non-prioritized scheme of managing handoff calls for a single traffic system is used here to find the blocking probability. Xie and Kuek’s traffic model is used to predict the teletraffic parameters. The value of BH is calculated using MATLAB for different values of parameters so as to find the minimum number of channels requiredso as to keep BH below 5%.
