Challenges and outputs The collaborative study framework has major advantages when conducting practical studies and developments of ITU Recommendations based on the relevant mid-and-long term leading edge trends in NGN technology. Several testing software tools and preliminary testing environments have been shared among CJK countries(SDOs). A part of those outputs is available to the people who interested in the similar studies and the investigations of specifications of ITU Recommendation provided as the out puts of our CJK Testbed studies.

4. Next steps  If there are other SDOs who promote standard technologies by use of the Testbed style environment, CJK would like to share experiences.  If experts in other SDOs are interested in tools of CJK Testbed, CCSA, TTA, and TTC are happy to talk with them.  If there are other SDOs who promote standard technologies by use of the Testbed style environment, CJK would like to share experiences.  If experts in other SDOs are interested in tools of CJK Testbed, CCSA, TTA, and TTC are happy to talk with them.

5. Subjects of the studies In order to investigate the technology integral to the worldwide services under the interconnected environment of the multiple NGNs owned by each country, we have been conducting both testbed studies and standardization studies in ITU-T involving China, Japan and Korea(CJK). Study 1: CCSA(CATR), TTA(ETRI), TTC(KDDI, OKI) Measurement and Evaluation of the quality of service (QoS) and the application layer quality (QoE; Quality of Experience) in order to control streams of the FMBC (Fixed Mobile & Broadcast Convergence) services based on the MPM (Management of Performance Measurement) functions.

Study 2: CCSA(CATR), TTA(ETRI), TTC(NTT) To achieve requirements for transport stratum on an NGN, a functionally distributed transport networking (FDTN) architecture which divides the functions of transport stratum into the control element (CE), the forwarding element (FE) and the service element (SE) has been studied. Study 2: CCSA(CATR), TTA(ETRI), TTC(NTT) To achieve requirements for transport stratum on an NGN, a functionally distributed transport networking (FDTN) architecture which divides the functions of transport stratum into the control element (CE), the forwarding element (FE) and the service element (SE) has been studied.

6. Achievement of Study 1 A new recommendation ITU-T Y.2173 which defines specifications of the MPM functions was consented(SG13) based on the study 1. Overall architecture for NGN performance management

7. Achievement of Study 2 A new supplement Y Sup.11 which describes application scenarios of the iSCP (independent scalable control plane, equivalent to FDTN) was approved based on the study 2. CE: Control Element SCE: Service Control Element FE: Forwarding Element SPE: Service Processing Element VNE: Virtual Network Element ME: Management Element
