Quality of service concept evolution for future telecommunication scenarios

In this paper a novel concept of "situation and location" based quality of service (QoS) control for next generation hybrid wireless system is investigated. A brief overview of the evolutionary paths involving the QoS concept is given and the new vision of I-centric telecommunications scenario is addressed. In such a context, a definition of a situation and location aware mechanism for QoS management and resource allocation is proposed by approaching the issue at a middleware layer in such a way as to make the underlying heterogeneous system completely transparent to the mobile user roaming across its segments
