Network-aided session management for adaptive context-aware multiparty communications

Recent years, from about the early 2000s, have been characterized by global broadband penetration, Fixed-Mobile-Convergence, Triple Play, and content provisioning over All-IP multimedia networks. Increasing demands in group-based multimedia sessions and market forces are fuelling the design of the future Internet, which is expected to fundamentally change the networking landscape in the upcoming years. Context, understood as sensed information that changes over time, has already led, to some extent, to service adaptation in terms of recognizing and using simple context, e.g. location. Context may also include network or personal state, location, or weather. To allow for session adaptation, it is important to use network and user context to enhance the existing service, keeping the user satisfied throughout the session.
