Handoff will become an increasingly important issue in mobile phone communications, especially in microcellular systems with the increase of handoff traffic between cells. Many approaches have been proposed for handoff analysis. In a previous analysis, it was assumed that the probability density function (pdf) of the speeds of cell-crossing terminals is the same as the pdf of the speeds of all terminals. In contrast to this assumption, we argue that both pdf's are unequal. The pdf of the speeds of cell-crossing terminals is given by a “biased sampling” formula. This boundary condition is used in our study and improves the accuracy of performance measures in handoff analysis. In previous work, a priority handoff system which has dedicated channels for handoff calls and uses a blocked call cleared (BCC) policy has been analyzed. In this paper, we use a different approach in performance analysis. The proposed approach has low computational complexity and high accuracy.
