The
predominant candidate for
current trend
of multimedia services
convergence with mobile/fixed networks and
broadcast-interactive applications is the IP
Multimedia Subsystem (IMS).
IMS entails novel business
opportunities
for pioneering and emerging
multimedia services,
such as IPTV and VoIP
video call
applications. However, this strong
commercial interest
on this promising convergent IMS
environment is
balanced by the lack of efficient
user/customer-centric network management mechanisms. ADAMANTIUM
proposes an IMS-compatible Multimedia
Content
Management System (MCMS)
focused on performing dynamic cross layer
adaptations for optimization of the user experience
in terms of perceptual quality for IPTV and VoIP services.
This multimodal
management system will be applied in an integrated
and coherent way along all the
network layers and delivery-chain nodes based on a
user/customer-centric approach rather than
a typical engineering one. Towards this,
the proposed management system will make use of advanced
IMS-compatible PQoS and NQoS monitoring and adaptation mechanisms
across the network
delivery-chain, enhancing in this way
the current IMS
management functions
by providing perceptual
awareness to
them. ADAMANTIUM MCMS will be implemented and demonstrated on
an
actual IMS platform installed over a UMTS access network,
where VoIP-based and
IPTV applications over IMS services will be provided.
