IMS and Mobile Multimedia

Standardization organizations such as ETSI, ITU are currently defining their vision of Next Generation Networks (NGNs), integrating heterogeneous wireless and wireline networks, with sub-systems dedicated to multimedia (IMS), security and Circuit emulation (PES). On the other hand, applications and services that go beyond basic features remain hard to develop and deploy.

The aim of this workshop is to serve as a platform for researchers from academia, research labs, manufacturers and operators to share their ideas, views, results and experiences in the field of IMS-based telecommunication with a special focus on security and services issues. The workshop will include presentations of theoretical and experimental achievements, innovative security systems, prototyping efforts, case studies, and advancements in technology.

Preliminary program

1. Converged Applications and Services

IMS applications services
Service mobility, continuity and maintenance
Instant messaging, Presence and event notification
Service creation environments
Service engines (e.g. Parlay, SIP Servlets, IMS)

2. VoIP, NGN and IMS Security

Intrusion and anomaly detection, prevention and protection for VoIP, NGN and IMS systems
DoS, SPIT, SPAM, Vishing
End-to-end security schemes
Inter-provider trust and verification schemes

3. Management, Resilience and QoS

P2P overlays for future telecommunication systems
Traffic monitoring, testing and performance measurement of VoIP, NGN and IMS traffic
QoS for mobile voice and video
High availability, reliability and jitter solutions for VoIP, NGN and IMS systems
