In this paper, we derive closed-form expressions for the call dropping probability and call completion probability for a cellular network with general distributions for the cell dwell time. In particular, we consider a non-homogeneous cellular network in which the handoff request failure in each cell follows a uniform distribution. We assume throughout this paper that the channel holding time is exponentially distributed but the cell dwell time has an arbitrary distribution. For special cases of the cell dwell time distribution, closed-form expressions for the call performance metrics are obtained.
