Performance analysis of reuse partitioning with mobile users

Reuse partitioning (RP) is a simple technique that can be used to increase system capacity. With RP, a cell is divided into several concentric regions, each associated with a different cluster size. In this paper, a traffic model is developed to analyze the impact of mobile users on an RP with fixed channel assignment system. The influence of user speed and cell size on the new call blocking probability, P_b , and the call dropping probability, P_d, is investigated. A simpler model which can be used to estimate P_b and P_d in some cases is described. The effect of reserving some channels for handoff calls on the capacity is studied. It is found that even though prioritized handoff can reduce P_d, it may also degrade the capacity
