Highlight of Current Activities(1)

• Resolution 76 Studies related to conformance and
  interoperability testing, assistance to
  developing countries, and a possible future ITU
  Mark programme which was approved in WTSA08
  instructs to take actions to all SGs to improve
  NGN interoperability.

TTC drives the discussion of NGN interoperability
in SG11.
3
Highlight of Current Activities(2) Discussion in
the NGN-GSI meeting

• A contribution proposed to develop a draft
  recommendation for the conformance testing and
  interoperability testing. This contribution was
  discussed in SG11, SG13 and SG16.
• The proposed draft recommendation for the
  conformance testing and interoperability testing
  are composed with a single framework
  Recommendation and series of Recommendations
  which include detail specifications for each
  service.
• The framework Recommendation includes procedure,
  requirements, architecture and document sets as
  well as the scope, definition and reference. It
  will be general and overview descriptions for the
  conformance testing and the interoperability
  testing.
• The subsidiary series of Recommendations include
  the detail descriptions for the specific service
  ant it will be created according to progress of
  study for each service.
• SG11 is developing two draft Recommendations
  Q.NGN interoperability and Q.VoIP conformance
  testing at NGN UNI

Strategic Direction Proposals to improve
interoperability

• TTC created new work group to discuss NGN
  interoperability and study new series of
  Recommendations NGN interoperability.
• Contributions, which include detailed technical
  information based on the TTC standard JT-3402,
  were submitted to the NGN-GSI meeting (April
  2010).
• Those proposals were agreed and captured in the
  annex to the Q.VoIP conformance testing at NGN
  UNI.

TTC propose to share our experiences and invite
technical information from various SDOs and
analyze them to find the solution to achieve the
NGN interoperability.

Proposed annex to the draft Rec. Q.VoIP
conformance Testing at NGN UNI

• TTC developed Technical Reports to specify the
  detailed protocol specifications at NGN UNI and
  NNI for interoperability between Japanese
  operators.
• TTC developed TTC standards JT-Q3401 and JT-Q3402
  which consist of the translation part of ITU-T
  Recommendations and TTC original specifications
  as Annex and Appendix.

Challenges Remaining BIG issues

• Protocol specifications are not developed in SG11
  therefore no interoperability tests can be
  provided for PSTN/ISDN simulation services.
  Task of SG11
• Accelerate the on going study for VoIP
  conformance testing and initiate the new work
  item for VoIP interoperability testing. Task of
  SG11
• Harmonization and/or integration of separate
  discussions in Q.3/SG13 and Q.8, 9,10/SG11
  relating to physical architecture for NGN
  interoperability. Task of NGN-GSI
• Iran submitted a contribution SIP-based Call
  Server Test Procedures (Iran, ASTAP17/EG.NGN/04)
  to the 17th ASTAP Forum (05 July 2010 - 09 July
  2010 Pattaya, Thailand). Developing countries
  seek detailed test specifications based on ITU-T
  standard.

Collaboration of member SDOs of GSC is needed.

Next Steps/Actions

• This presentation introduces the TTC activities
  in the April NGN-GSI meeting of the discussion on
  NGN interoperability.
• SG11 promotes to develop draft Recommendations
  for NGN interoperability including the general
  framework document and technical specifications
  document for VoIP conformance testing and VoIP
  interoperability testing.
• SG16 are developing the series of the draft
  Recommendations for IPTV conformance testing.
• The first ITU-T IPTV interop event was held in
  Geneva 20-23 July 2010 which is driven by SG16.
• Member SDOs of GSC should promote the study of
  NGN interoperability in ITU-T NGN-GSI.
