Mobility modelling and channel holding time distribution in cellular mobile communication systems

Abstract

In a cellular mobile communication system, the time spent by a user on a particular channel in a given cell is defined as the channel holding time. This paper aims to characterize the probability distribution of the channel holding time. Mobility of users under most generalized conditions have been formulated mathematically and based on this formulation a computer simulation has been developed. This mobility model is used to examine cell residence time distribution under generalized conditions. Given the residence time distribution, the channel holding time distribution is found. The results show that the negative exponential distribution is a good approximation for the mobile channel holding time distribution.
