Abstract	The recent spreading of public wireless infrastructures allowing for higher data rates makes mobile communications networks a very attractive platform for distribution of multimedia content. At the same time, limited resources in public wireless networks pose serious questions on how to bring services and multimedia to terminals to be used anywhere. Content adaptation is required in order to bring the best perceptual experience to the end-user while optimizing resources usage. Unfortunately, content adaptation is very difficult to achieve and is usually related to bandwidth availability only. In this paper we propose to extend existing service provisioning architectures with an asynchronous notification system to keep up-to-date the whole set of user profile data during service provisioning. We argue that the average multimedia application behavior, still adhering to a model based on a very limited number of choices, is not affected by increased reaction time and coarse-grained parameters responsivity. Furthermore, introduction of asynchronous notifications will enable service providers to adapt content considering any parameter characterizing the user profile, not just available bandwidth.
