Hand-off traffic characterisation in cellular networks under non-classical arrivals and gamma service time distributions

Classically cellular networks have been analysed using Poisson call arrivals and negative exponential channel holding times. However, measurements on live networks have generally invalidated these assumptions. We propose a method for analysing cellular networks under more generalised arrival processes and more realistic channel holding time distributions. We present a model for accurately characterising the hand-off traffic offered by a cell to its neighbour in a simple two-cell scenario. Our two-cell model easily lends itself to be used as building blocks for analysing more general cellular network layouts. The results of the two-cell scenario may be used to determine customer-orientated grade of service parameters such as new call blocking and forced termination probability. We illustrate the accuracy of our analysis using comparison with simulation results
