 Abstract: Statistical modeling and forecasting of telecommunications data are considered. Main mobile traffic events (SMS, Voice calls, Mobile data) are smoothed using B-spline functions and later analyzed in a functional framework. Functional linear auto-regression models are fitted using both bottom-up and top-down design methodologies. The advantages and disadvantages of both approaches for the prediction of mobile telephone users' habits are discussed.
