Analysis of traffic distributions in GSM

The main aim of this work is to study traffic models for mobile networks and to compare them with real data from a GSM operator. Accurate air interface traffic forecasting is of great importance in mobile networks for achieving quality and cost requirements. Previous studies of traffic modeling in mobile networks have tended to derive distributions to fit the measured data for the arrival rate and call holding processes or derive expressions for call blocking on the air interface for different handover and channel assignment procedures. In this work, call blocking and handover failure probabilities of the Telecel GSM network are presented. A theoretical analysis is compared with measured data from base station "Parede" in the south of Lisbon.
