Introduction, Objectives, Agenda • Opening of meeting • Alain le Roux (TISPAN Chairman) and Bill O’Shea (ATIS NGN FG Chairman) opened the meeting and welcomed delegates to the joint Meeting • Meeting Objectives • Presented in [TD_01_ATIS_TISPAN_Objectives] • Exchange of information • Seek areas of commonality, identify differences in respective NGN standardization initiatives • Next Steps on areas for cooperation • Agenda • Presented in [TD_06_ATIS_TISPAN_AGENDA] • Agenda and was approved Meeting on “NGN Framework” – SUMMARY -

  4. 2. Overview of ATIS_NGN activities • Overview of ATIS • Presented in [TD_07_ATIS_Overview] • Presents ATIS and their approach to Standardization • ATIS are streamlining and prioritizing standards work • Removing redundancy and coordinating standards activities • Introduces the ATIS NGN Framework Part 1 • Presents the goals for collaboration Meeting on “NGN Framework” – SUMMARY -

Similar situation with OMA, this needs to be considered. • TISPAN plans approve the appropriate H.248 profile for AGW in May 2005 • Number portability could be an area for cooperation between ETSI TISPAN and ATIS. Meeting on “NGN Framework” – SUMMARY -

  6. 4. ATIS NGN Framework document • Part 1 – NGN Definitions, requirements, and Architecture (Issue 1.0, Nov. 2004) • Full document in [TD_08_ATIS_NGN_Framework] • Contains the ATIS Issue 1.0 "NGN Framework document", up to Section 3, sent to TISPAN and other SDOs for comments • Provides a clear description of the various areas covered by the Framework document • ATIS welcomes comments from ETSI TISPAN on the content of this document Meeting on “NGN Framework” – SUMMARY -

  7. 4.1 General requirements, End-user applications • Overview • Presented in slides 6 to 12 of [TD_09_ATIS_NGN_Framework_overview] • Interconnection • Convergence (fixed/mobile/enterprise) • Access network criteria • Infrastructure evolution & Legacy services • End-to-end transparency • Services guiding principles (for converged networks) • Definition of NGN Interconnection requirements suggested as an area of cooperation Meeting on “NGN Framework” – SUMMARY -

  8. 4.2 ATIS NGN Network service enablers • Presented in slides 13 to 18 of [TD_09_ATIS_NGN_Framework_overview] • QoS • TISPAN_NGN R1 focuses on Access QoS • End-to-End QoS will be addressed in TISPAN_NGN R2 • Presence and Personal profiles • TISPAN suggested that ATIS examine some of the work currently being done in TISPAN, 3GPP and OMA Meeting on “NGN Framework” – SUMMARY -

  9. 4.3 Underlying Network/Support capabilities • Presented in slides 19-20 of [TD_09_ATIS_NGN_Framework_overview] • Security • Need to protect access to both network and subscriber information. • Main issue is authentication and integrity at all levels. Confidentiality is less important. • There is an additional threat to telecommunications from terrorist attack. Need for authentication of the originator (or of the access). Meeting on “NGN Framework” – SUMMARY -

  12. 4.6 Framework architecture • Presented in slides 35-47 of [TD_09_ATIS_NGN_Framework_overview] • Identifies 4 key "layers" • Network Infrastructure (IP transport functions) • Sessions and Policy control functions • Application and Service capability functions • OAM&P Functions • Multiple Service Provider environment issues • Multiple Administrative and Technology domains • Interworking between multiple instances of Session, Policy and Service control • Interworking with legacy signalling/control instances Meeting on “NGN Framework” – SUMMARY -

  13. 5. Review of the Workshop "IMS over Fixed Access" results/issues • Workshop Highlights • Presented in [TD_05_Highlights_from_TISPAN_3GPP] • Presents the highlights of the discussions between TISPAN and 3GPP relating to the development on Fixed access to 3GPP IMS • Identifies areas of common work • Defines a mechanism for TISPAN to reference 3GPP IMS specifications • Discussions • ATIS supports the goal of a single converged and unique IMS Core applicable to 3G Mobile and Fixed NGN • ATIS PTSC is looking at re-establishing the relationships with TISPAN to discuss issues incl.

Note – LI requirements are being coordinated thru existing arrangements. • Future interactions • The 4 areas listed above are to be addressed in NGN Rel-2 scope • ATIS involvement in TISPAN_NGN Rel-1 work is welcome (incl. potential endorsements) • There is a need for discussions between ATIS & TISPAN bodies to put in place mechanisms and identify contacts Meeting on “NGN Framework” – SUMMARY -

  16. 8. Future Working arrangements • Existing contacts • TISPAN-ATIS liaison officers are Susan Sabatier (ETSI) and Tim Jeffries (ATIS) • Contacts to be put in place for each of the 4 areas of joint activities.
