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

3. Overview of ETSI TISPAN_NGN activities• TISPAN NGN Ongoing activities and plans
- Presented in [TD_02_TISPAN_NGN_status]- Presents the ETSI TISPAN vision of NGN- Explains the TISPAN structure and working methods- Lists the Service requirements for TISPAN NGN- Describes work activities in various working groups- Presents the general TISPAN NGN architecture and
motivators for re-use of 3GPP IMS• Discussions
- 3GPP2 also references 3GPP IMS, and may also need to be involved in these discussions (for global connection scenarios). 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.

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

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

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).

4.4 Business model driven requirements
• Presented in slides 22-30 of [TD_09_ATIS_NGN_Framework_overview]
- 4 Business drivers:- New Retail revenue- New Wholesale revenue- Cost reduction for existing services- Regulatory requirements
- 3 Keys for success- Customization through User Profile- Transparent third Party providers- Seamless service delivery

4.5 US Regulatory requirements• Presented in slides 31-35 of
[TD_09_ATIS_NGN_Framework_overview]
- National Security (LI) and critical infrastructure (ETS)
- Consumer requirements (E9-1-1)- Operation requirements (Number Portability,
Number Pooling, Accounting, FCC rules)

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

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. IP-IP Connect, Security and H.248
- TISPAN would appreciate being informed of the ATIS timescales

6. TISPAN feedback on ATIS Framework
• There appear, at high level, a full alignment between ATIS NGN Framework and the TISPAN views and approaches:
– Business model, Service enablers, Architecture …– No significant differences are anticipated
concerning Regulatory requirements• ATIS expects to pursue
– On priorities, Release definition and planning– Gap analysis, e.g. on the basis of TISPAN_NGN
Release 1• ETSI TISPAN looking for cooperation
– Will inform ATIS NGN FG of progress on their R1– Send feedback on Release definition and gap
analysis

7. Next steps/Future interactions …• Areas of Common interest between TISPAN /
ATIS- 1) NGN interconnect including SBC (Session Border Control)
functions- 2) Emergency communications including emergency
identification and routing- 3) User identification, number portability, ENUM, and
directory services (including GRX issues)- 4) Security requirements and Access agnostic solutions
(incl. gap analysis). 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

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. They will be responsible for coordinating and tracking progress
• Working arrangements- To be arranged by Liaison officers
Note – The 4 areas of Joint activities do not preclude others to occur (e.g. NGN-OSS, Protocol profiles and interoperability)
Note – The exact arrangements will comply with the ETSI and ATIS cooperation agreements.
