Convergence at many levels

User’s viewpoint Converged services across variety of networks Converged devices (e.g. Mobile phone that works also with Wi-Fi) Does not require converged networks

Service provider’s viewpoint Converged for users .. User retention/ new revenue Common converged network ..lower OPEX, reuse of components

Application provider’s viewpoint Personalized services to users independent of access or network Global services independent of service providers or location

Equipment manufacturer’s viewpoint Enable new functions/ simplify multiple devices New components to enable new services and common reuse

Convergence, Multimedia and Personalization

Every new service meant new network (Blackberry, TV, Paging, etc.)

Convergence brings one infrastructure for many services .. Many choices for users

Session Control

Scenario: Cell phone user is in a conference call and has subscribed to wireless re-connect service. The cell phone user gets dropped. In this case, the re-connect announcement should not be played back into the audio conference (-> feature interaction problem).

Service Coordinator retrieves feature interaction policies (indicating that a media server should not be used) and notifies the Wireless Re-Connect application.

Wireless Re-Connect application: Connects the conference bridge to a call park server instead of a media server.

IMS Rel-6 Subscription ModelIMS Rel-6 Subscription Model

Unique IMS Subscription Each IMS User can have more than one Private Identity

E.g., a subscription can support multiple devices (sip phone, IPTV, …) and SIM cards Each IMS user can have more than one Public Identity per Private Identity Each Public User Identity is assigned exactly one Service Profile

But a Service Profile may be assigned to more than one Public User Identity Example of multiple Private Identities:

IMS handset with USIM card (using personal Public Identity IMPU-1 and one Office Public Identity IMPU-2) IMS WLAN card with soft USIM card (using WLAN Public Identity IMPU-3 and one Office Public Identity IMPU-2)
