This article presents a general evaluation of handof dwell time distribution based on geometric analysis methods Considering the geometric characteristic of the deployed secto pattern, and the distribution of the users’ position and the moving direction in the given sector, the general formulas of the probability density function of sector handoff dwell time ar derived. Some numerical results are also presented fo illustration.
