Convergence at many levels: 

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: 

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 New services possible Video clips to cell phones; Voice over cable Choices of devices and multimedia Need mechanisms in the Network to support personalization User Profile Data Policy Definition Policy Execution

The Learning network : 

The Learning network Whereabouts of user Location, presence, preferred media, devices, etc. Behavior of user User’s call patterns, Frequent numbers, preferences for handling of different calls, call usage based on time, etc. Network traffic behavior Congestion, delay and bandwidth usage Content distribution needs (place and time) Network outage and pricing information Need mechanism for capture Information Network traffic and event monitoring Data Mining Learning Rules

Application Interaction: 

Service Broker 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.

Active Phone Book vision for personalization: 

Active Phone Book vision for personalization Interpret raw presence to obtain availability that is filtered by Context, Preferences, Requester I’ve done enough speaking for today, unless my boss calls I’ll be away from the desk for a little while, but friends and family can reach me Bad hair day, no video for me, except for my family

One key to rich, flexible personalization: Apply the logic every time a request is made : 

One key to rich, flexible personalization: Apply the logic every time a request is made Raw user Presence/ Location Request User Preferences Decision, e.g., Michael is available to Sally by cell phone only Sally Michael’s preferences, learned and/or pre-provisioned Where is Michael? If working, let co-workers see me Michael is on freeway between office and home Vortex Personalization Infrastructure Key Issue: Many different kinds of users; many applications Vortex makes it cheap and fast to specify the different decisioning logic for diff apps and user segments
