Enhancing 3G Cellular Systems with User Profiling Techniques for Multimedia Application QoS Adaptation

In this paper the authors' attention is on a dynamic QoS adaptation mechanism whose functional behavior is driven by underlying system conditions, user exigencies and preferences. The proposed mechanism differs from analogous systems as it dynamically estimates the user preferences, through a "user profiling" activity, and uses the estimated profile to dynamically adapt the resources devoted to the traffic flow. The procedure is completely automated and quite fast. In this paper the proposed mechanism is introduced into a 3G system and its effectiveness tested under different conditions.
