Terminal Migration Model in which Cell Dwell Time is Defined by Different Probability Distributions in Different Cells

In evaluating the teletraffic of mobile communication networks, it is important to model the motion of terminals. In the previous migration model, mobility characteristics of terminals, such as cell dwell time, have been expressed by a single probability distribution. In this paper, we discuss the modeling of the cell dwell time of terminals in each cell. Using measured data we show that cell dwell time differs from cell to cell and follows log-normal distributions rather than conventional exponential distributions. We also use computer simulations to compare the results predicted by a migration model in which cell dwell time is defined by probability distributions that differ from cell to cell with the results predicted by the conventional migration.
