1 Multimedia Applications in a Converged World Sid Ahuja Alcatel-Lucent, Bell Labs VP, Convergence and Software Research

2 Convergence, VoIP, IMS and NGN IP Transformation.. VoIP Lower cost of components and networks (CAPEX) Lower operations cost (OPEX) Simplification Many new devices and services Each service a separate network (e.g. Blackberry) Combine networks.. IP Core.. IMS New Services Ring Tones, Video Mail, Location based services, etc.

3 Network Evolution Separation of Services and Networks

4 Single Service (Telephony) -> Single Network Content Networks Users Messaging, Ring Tones

5 Multiple Services -> Multiple Networks CONTENT NETWORKS USERS TV Studios, Ads, Movies Television Networks Web Servers, AOL, Yahoo Data Networks (Internet) Messaging, Ring Tones Phone Networks

6 Hundreds of Services -> Virtual Networks -> Common Core CONTENT NETWORKS USERS TV Studios, Ads, Movies Web Servers, AOL, Yahoo Common Data Network Messaging, Ring Tones

7 Convergence in the Core: Diversity at edge Internet Cable IP Network 2G/3G User Data NGN Network IP Packet Core Application Servers Application Gateway 802.xx Access Packet Mobile Network Media Server Media Gateway Circuit Mobile Network

8 NGN: What s Needed? Common packet architecture/protocols.. IP Common Addressing and Authenticaiton.. DNS, SIP addresses, URL, Common Signaling.. SIP QOS support for different media (MPLS, RSVP, RTP, etc.) Common interface standards for call control, gateways, service requirements, policies etc,..ims Support for new Service Oriented Architectures Support for distribution of intelligence.. Peer to Peer applications

Application Interaction Wireless Re-Connect Resource Control Service Coordinator Data Matrix Wireless Network

wireless re-connect service. The cell phone user gets dropped.

18 Application Interaction Wireless Re-Connect Resource Control Service Coordinator Data Matrix Wireless Network Session Control Bridge D User A User B 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.
