Provisioning IMS-based seamless triple play services over different access networks

Triple Play is considered as delivering of telephony (VoIP), Internet, and TV services on the top of a single bearer technology plus value added services like presence, community-based services, multimedia streaming services etc. Since IP Multimedia Subsystem (IMS) has been designed to enable the convergence of fixed and mobile networks to provide combinational services with QoS, so it offers the comprehensive architecture for provisioning of triple play services. However further studies are required in order to provide triple-play services seamlessly over different access networks. This paper describes a converged IMS (IP Multimedia Subsystem)/TISPAN Service Delivery Platform (SDP) architecture to provide triple play services and focuses on the issues of access and transport layers for providing seamless environment in UMTS (Universal Mobile Telecommunications System) and DVB (Digital Video Broadcast). This work is being developed in the context of extending the FOKUS IMS testbed to offer new IPTV testing capabilities to the Pan-European Network of testbeds (Panlab Project) federation.
