  1. Activity of TTC interoperability Yasubumi Chimura Hideo Himeno TTC Interoperability-AG

  2. Highlight of Current Activities TTC and HATS held the NGN interoperability event and workshop in September 2012, Tokyo. Several NGN terminal (VoIP, video-phone) venders participated. These events were successful . TTC is continuously contributing to ITU-T SG11 to improve NGN interoperability since Res.76 was adopted in WTSA12. TTC proposed new draft Rec. Q.3949 “Service testing framework for real-time multimedia service at NGN UNI”. This Recommendation was approved in ITU-T SG11 meeting in June 2012 respectively. TTC proposes the detailed signalling specifications and test specifications based on the TTC and HATS activities on NGN interoperability.

  3. Strategic Direction HATS SIP/MPEG4 Interoperability Test Guideline ITU-T Rec. vs HATS Guideline Up Stream ITU-T NGN Service Test Specification Down Stream HATS NGN Interoperability Test Guideline TEST Registration DB of ITU-T Benefit Global Contributionfrom Japan Vendors Expand Asia BroadbandMarket TTC and HATS develop national testing specifications and adapt them to global standards. TTC contributes to ITU-T Standardization of C&I service testing. Consideration to register test result to ITU-T C&I DB is discussed.

  4. Challenges • NGN service testing specifications are constructed with a single framework Rec. Q.3909 and a series of Recommendations which include detailed specifications for each service. • TTCdevelops Recs. “Video-conf-testing” and “IP-FAX testing”. completed Q.3909 Framework of NGN interoprability completed completed drafting drafting Q.3948 VoIP service testing at NGN UNI Rev. Q.3949 Multimedia service testing Q.Video-Conf-testing Video Conference testing Q.IP-FAX-testing IP-FAX testing drafting Q.CDIV Q.OIP/OIR PSTN/ISDN simulation service testing Annex SD(MPEG) SD(H263) HD(H264)

  5. Next Steps / Actions APT Conformance and Interoperability event 9-10 September 2013, Bangkok Thailand • Schedule • Workshop: 9 -10 September 2013 • Conformance and interoperability testing: 9 -10 September 2013 • Showcasing: 9 - 14 September 2013 • Testing potential items • NGN (VoIP, Video conference) • IPTV(including IPTV-MAFR (Multimedia Application Framework)) • Showcasing potential items • HTML5, Smart TV, Digital signage, SDN, M2M/IoT, etc.

  6. Next Steps / Actions The interoperability tests should be based on ITU-T Recommendations, and it is a pragmatic way to achieve by regional SDOs. Such a global interoperability event provides good opportunities to resolve the issues for both of developed and developing countries. This new collaboration framework such as the interoperability events will foster mutual understanding and cooperation among regional/national SDOs . TTC and HATS will be able to take a certain role in the framework through its experiences.

  10. Resolution GSC-16/28 GSC-16 meeting agreed the Resolution GSC-16/28 Interoperability. It is expected for PSOs to act the role according to Resolution GSC-16/28.

  11. HATS (1/4) - Introduction - HATS : Promotion Conference of Harmonization of Advanced Telecommunication Systems HATS is a Non-Profit organization that ensure interconnectivity and interoperability of info-communication equipment developed by various manufacturers HATS was established in Aug. 1988. - Members: info-communications carriers, vendors, TTC, MIC*1 - Secretariat: Communications and Information network Association of Japan (CIAJ) Note*1:MIC(Ministry of Internal Affairs and Communication, For the details, http://www.ciaj.or.jp/hats/english/about.html

  12. HATS (2/4)- Structure - • Chairman • Executive Committee • decides basic policies, overall HATS • activities and establishment of new TILC • Test Implementation Liaison Committees(TILCs) • Plans & implements • interconnectivity test • examines test method/procedure • reviews & studies test result Management Committee Ad-hoc on optical access network • Steering Committee • researches on ICT standardization • & market trends • coordinates TILCs activities • liaises with other organizations Facsimile TILC PBX Telecom Server TILC Multimedia Comm. TILC Advisory Committee - gives advice on overall HATS activities VoIP WG Video Conference WG • Promotion Committee • & Demonstration Committee • disseminates HATS activities • plans/arranges seminars & demonstrations Home-Network WG IP-Camera WG Secretariat: Communications and Information network Association of Japan (CIAJ)

  13. HATS (3/4)- The Interconnectivity Test Range Targeted - Whole functions supported by each equipment Original functions supported by each equipment Optional functions Essential functions Activity Expansion Functions based on standard + Application and Network Layer Basic Functions　→　Interconnection test range (Essential functions) + (a part of Optional functions)

  14. HATS (4/4)- Role of HATS - ITU, ISO, IEEE, IETF, etc. TTC:Telecommunication Technology Committee Confirm test guideline Vendors R&D of new equipment Telecom. Carriers Participate Cooperate Market HATS Improve • - plans interconnectivity tests • examines test methods/procedures(test guidelines) • builds test beds & executes interconnectivity tests • on round robin basis • (Basically, participants share the detail test results, • and also share all costs for the tests.) • - reviews&studies test results • (- release abstracts of the test results to press) Feed back
