Goal
• What : End to End QoS in NGN Context
(mobility, User Centric, convergence)
• Why : Service delivery
– Equipment : Computing delivery (CPU and memory)
– Network : Media delivery
• How : With SIP+ (Service provisioning
according to QoS)

Service delivery : SIP+ for QoS E2E dynamic management
(Terminal, Access Network, Core Network, Service Level)
Session regarding User request Service composition regarding User Needs = SE4+SE6+SE8
Session after SE4 deterioration Dynamic Provisioning by equivalent QoS = SE2+SE6+SE8
Session after mobility
Dynamic re provisioning after mobility = SE3+SE6+SE8

Conclusion : Actions
• Identify protocol modifications (SIP+) and
propose its to IETF
• Propose service provisioning mechanisms
regarding QoS needs required by the User
• Propose service process continuity
• Provide service delivery during User
mobility
