Abstract

In future multimedia systems, seamless access to application services on different devices available to users in their vicinity, will be commonplace. The availability of these services will change as the mobile user moves. Current 3G multimedia systems do not support access to multiple applications operating on multiple different devices in the context of a session or indeed seamless device session handover. Considering these requirements, we outline two multimedia communication platforms which potentially solve this problem. This paper describes a backward compatible architecture based on the widely adopted Session Initiation Protocol (SIP) and also outlines a clean slate approach from ITU-T SG 16 called the Advanced Multimedia System (AMS). For each of these solutions we describe and discuss in terms of architecture, signalling and capability negotiation, what we view as the most critical functions in future multimedia systems design. The result of this comparison displays the advantages and disadvantages of each approach, and outlines solutions to satisfy challenges of current and future multimedia systems based on the service access requirement in ubiquitous environments. Furthermore this comparison is used to suggest approaches that are best suited for future multimedia system design
