User-centric session et QoS dynamique pour une approche intégrée du NGN

Abstract : The ability to provide seamless mobility with E2E QoS will be critical to the success of NGN (Next Generation Network). For this aim, the research of this thesis is positioned at the interconnection of three areas: mobility, heterogeneity and user preferences. Our first proposal is in organizational and functional dimensions, for which we advocate the convergence of three levels in the network (user plane, control plane and management plane) and associated functionality. Thus we get a dynamic QoS-oriented approach in order to satisfy the "User-Centric". For implementing the E2E QoS including personalization in the "User-Centric" session, we proposed a "dynamic E2E QoS Signalling" in the service layer. The proposal provides an end-to-end provisioning among the service components with information on four levels (equipment, access network, core network and service). Considering any impact of mobility, we proposed also a "cross layer E2E Session Binding" in our architecture for ensuring information consistency on the four levels of visibility. Meanwhile, our contribution in the informational dimension focused on the profiles involved in each stage of service life cycle including the QoS criteria, which provide a generic image of the components of the user's system and all environmental resources. Finally, we presented the feasibility of our proposals through the experiments on our platform
