Abstract :
We investigate the validity of the analytical model of new call channel limiting scheme (NCCL) by means of simulation. NCCL limits new calls to access the total channels with parameter a while handover calls have no restriction to access the channels. We focus on the effects of users´ mobility and the parameter a on the blocking probabilities of new and handover calls. We observe that the analytical model presents a good match to the simulation model for low mobility users whereas there exists a small disagreement for high mobility users. Furthermore, we find that the variability of mobile users´ velocity affects the applicability of the analytical model, in particular, for small α and light traffic. We extend the analytical model by including the influence of the distribution of mobile users´ velocity. We show that the extended analytical model yields better agreement with the simulation results.
