  1. P607 Top-down approach applied to multimedia services José Jaime Ferreira - T3 leader Portugal Telecom jaime@inesctel.pt

  2. Budget 100 MM (overall) Duration July 96 to January 98 Partners AF, CH, DT, FT, IT, PT, TF, TI. P607 Facts & Figures

  3. Project Objectives and approach Network Architecture (IN - B-ISDN) Information Model SIB model (SELECT SIB Resource Allocation Op.) Service model (Activation of Add-on Video Conference) New INAP information flows Conclusions Overview of Presentation

  4. Investigate the integration of IN / B-ISDN Network architecture Call Models and protocols Model benchmark Multimedia services using a Top down IN approach Provide inputs to IN CS-2 and CS-3 definition new SIBs new INAP Information flows call-connection separation, CPH, ICA Projectobjectives

  5. Model a set of Benchmark Multimedia Services at a high level (IN GFP) Map GFP descriptions to a refined IN - B-ISDN architecture, at a medium level (IN DFP). Build detailed SDL Model of MM service, IN and B-ISDN functional entities involved. Simulation, validation and conclusions Top-Down Approach

  15. From service modelling, new SIBs and INAP information flows were identified. Ongoing project studies, covering the concepts of Session, Call Party Handling and call models were pursued and used as input to standards. Open issues and new directions were identified. A solution for IN-assisted resource reservation was designed. Results
