Due to scarce radio resources (e.g., wireless link bandwidth), the cell size is likely to become smaller to increase the frequency reuse ratio, especially in next generation mobile cellular networks. In this scenario, the analysis of handoff traffic is crucial for adequate QoS provisioning. With the assumption that incoming handoff traffic into a cell is equivalent to outgoing handoff traffic from the cell, we propose an iterative computation technique to analyze handoff traffic approximately. The iterative relaxation method is employed to calculate the steady state probabilities. The call blocking probability and the handoff dropping probability are accordingly obtained. We conduct the approximate analysis of handoff traffic in the case of trunk reservation call admission policy and compare the results with those of simulation experiments.
