In this paper, the authors develop an analytical study of the mobility in cellular networks and its impact on quality of service and outage probability. They first express analytically the downlink other-cell interference factor f by using a fluid model network. It is defined here as the ratio of outer cell received power to the inner cell received power. It allows the authors to analyze users' mobility and to derive expressions of the outage probability. They show that mobility can modify the capacity of a cell and they quantify the outage probability variations. The authors moreover establish how mobility plays a role in quality of service management.
