• TTC is continuously contributing to ITU-T SG11 to improve NGN interoperability since Res.76 was adopted in WTSA08.

• TTC proposed new draft Recommendations Q.3903 “NGN interoperability” and Q.3948 “Service testing framework for VoIP at NGN UNI”. These Recommendations were approved in ITU-T SG11 meeting in May and October 2011 respectively.

• TTC proposes the detailed signalling specifications and test specifications based on the TTC and HATS activities on NGN interoperability.

• TTC members have been actively participating in IPTV Interop Events conducted by ITU-T SG16 and contributing to JCA-CIT meeting.

• TTC developed TTC standards JT-Q3401 and JT-Q3402 to specify the detailed protocol specifications at NGN UNI and NNI for interoperability between Japanese operators.

• TTC proposes our experiences to ITU-T SG11 and invites contributions from various SDOs based on this and develop the global standards.

Next Steps / ActionsNext Steps / Actions

Launching New Work Programme “PSTN/ISDN simulation service”

• ITU-T Rec. Q.2211 defines – OIP, OIR, TIP, TIR, MCID, ACR, CDIV, HOLD, CB, CCBS, CW, MWI, CONF,

AOC, ECT, RC, UPT, CRBT, CRT• Develop protocol specifications to global deployment

– Step 1: Define the target services of PSTN/ISDN simulation services to develop service protocol specifications

– Step 2: Define the reference base specification of SDOs (ex. TTC, ETSI, 3GPP)

– Step 3: Modify/re-define/endorse base reference specifications and adjust them to ITU-T requirements and architectures, etc.

Next Steps / ActionsNext Steps / Actions• Support developing countries

– Many efforts on interoperability have been done and are on-going in various SDOs such as developing protocol specifications, test specifications and examination of interop events. But there are still interoperability problems in the developing countries. SDOs have to support the deployment and build up the human capabilities in the developing countries.

• Key roll of ITU-T– ITU-T should take the lead coordinating role in the harmonization of various

standards based on the concept of consistent end-to-end interoperability.– Vigorous protocols are developed in the vigorous SDO. ITU-T should study

the practical solution and promote the deployment of interoperable and affordable NGN equipment.

TTC proposes to reaffirm the HIS interoperability.
