  1. 1. Report of CJK 7th NGN-WG Meeting October 11, 2006 1. Opening of the meeting The 7th CJK NGN-WG meeting was held at Tokyo, Japan on October 10 and 11, 2006. The meeting was driven by the new management team agreed by the last meeting. It was chaired by Mr. Taesang CHOI of TTA, with Ms. Duo LIU of CCSA and Mr. Naotaka MORITA of TTC as vice chair persons. 2. Approval of the Agenda With the slight change of document order under NGN-test bed issue, the agenda given by CJK7_NGNWG7_01R2 proposed by the chairman was approved. 3. Document list and allocation Annex A to the meeting report shows the document list and its arrangement at this meeting. All documents are available at the web site below. 4. Review of the last meeting result The meeting report of the CJK 6th meeting was reviewed. It is given in CJK6_NGNWG6_26. 5. Editing activity of ITU-T NGN Draft Recommendations NGN-WG-010: Mr. Hideo IMANAKA (TTC) summarized the achievement of CJK editing activities so far and proposed continuing it. He also proposed determining the priority of target documents for future CJK editing activity. NGN-WG-002: Mr. Chae-sub LEE (TTA) also proposed continuing the drafting activity. He raised a couple of open items to be confirmed before moving on to the
  2. 2. next phase, such as coverage of study area and relationship with other activities. During the discussion, it was expressed the importance of protocol work including QoS signalling. The meeting agreed to extend the scope of editing activity into signalling and FMC aspects, which are covered by SGs 11 and 19. It was noted that since some documents are targeted to complete at the next NGN-GSI meeting, such as Y.CSF and Q.NNI_profile, they may be too urgent to be dealt by the editing activity. A list of target documents was produced to show high interests from CJK point of view. It is given in Annex B to the report. Highest priority was put in four draft Recommendations such as Y.NGN-R2-Reqts, Y.123.qos, Y.mpm, and Q.NNI_profile. The meeting agreed to put CJK efforts to progress identified documents as much as possible. The list may be extended according to new inputs and results at the ITU-T NGN-GSI meeting in October 2006. To establish common and detailed technical views on identified draft Recommendations, the meeting agreed to have a specific technical meeting in Geneva during ITU-T NGN-GSI time frame. Detailed meeting schedule is given in Section of future meeting plan. After the ad-hoc meeting, virtual meetings will be planned led by leaders responsible for each document. Concern was raised about how to characterize Release 2. It was noted that, regardless of Release, ongoing draft Recommendations should be respected. 6. Test bed activity NGN-WG-005: Mr. Taesang Choi • (TTA) made a report on ongoing NGN test bed activity. CCSA and TTA have formed an engineering team, which has identified several test scenarios and chosen possible sequence of tests. Preliminary network connectivity test has already performed in September 2006. The first test is planned in November or December and will be reported at the next 8th CJK NGN-WG meeting. NGN-WG-003: Mr. Taesang Choi (TTA) replied to the initial CCSA’s proposal on NGN test bed conditions. The reply selects available scenarios which are mainly based on SIP terminal with two SIP
  3. 3. proxies. CCSA confirmed the replied URI schemes and codecs. TTA has a plan to accommodate other terminals beyond SIP terminals in the near future. NGN-WG-009: Ms Xueli Zhang (CCSA) introduced test cases and the description of NGN test bed which had been proposed from CCSA to TTA. Based on the proposal, CCSA and TTA made a progress on the arrangement of the test bed architecture and specification of the test scenarios and items, which are described above. 7. IPTV issue NGN-WG-013: Mr. Hideo IMANAKA (TTC) proposed IPTV-ad hoc activity in CJK to concentrate on NGN-related issues to harmonize with NGN standardization. And he requested that other issues, such as DRM, metadata, and coding, should not be discussed in CJK IPTV-ad hoc group because there are few experts in CJK NGN-WG. He also proposed organizing CJK editing teams to edit the deliverables of FG-IPTV, with three candidate documents which are closely related to NGN. NGN-WG-008: Mr. Chae-sub LEE (TTA) also proposed how to apply successful editing activity to IPTV deliverables. His priority analysis of 13 candidate deliverables is based on three criteria such as 1) urgency from market perspectives, 2) commonality of interests among CJK, and 3) fundamental and framework nature of the deliverables. The meeting agreed to cover all IPTV issues starting with six areas proposed by TTA, and put higher priority on two NGN-related areas such as requirements and architecture and network and control. 8. QoS Related NGN Technical issues NGN-WG-011: Mr. Hideaki YAMADA (TTC) introduced a dynamic QoS control scheme for session-oriented services based on RACF. He proposed a mechanism based on RTCP and RTCP extensions to capture performance information of multiple portions of a network. According to the information, a terminal is able to adapt media traffic to improve or maintain performance. NGN-WG-012: Following the previous contribution, Mr. Satoshi UEMURA (TTC)
  4. 4. clarified requirements for a terminal to react against available information obtained by the proposed mechanism given in NGN-WG-011. During the discussion, it was recognized that terminal behavior is a key factor of the mechanism, and will be a subject of Release 2. It was recognized that they are useful and worthwhile to study further. 9. NGN Test bed Future Issues NGN-WG-007: Mr. Young-Wook Cha (TTA) introduced RACF functionality briefly especially with the main focus given on the application of CJK NGN test bed. He described several possible options regarding the selection of RACF functionality for CJK NGN testing. And he proposed recommended options for the testing of RACF over CJK NGN test bed. Comments were made from CCSA that the mapping of RACF functionality into physical network elements is an important issue to be identified and RACF protocol standardization work is still going on in SG11 and it seems to be a little bit early to discuss on testing. Meeting agreed to continue the discussion and information exchanges on this topic in the future meetings. TTA is also planned to bring a further detailed testing plan in the next meeting. NGN-WG-006: Mr. Hong-Shik Park (TTA) proposed setting up CJK NGN IPTV test bed. In his proposal, he suggested two phases: SIP-based SD grade IPTV test bed and IMS-based HD grade IPTV test bed. The specific time schedule hasn’t been described this time but will be provided in a next meeting. Meeting feels that setting up such test bed is still premature since the relevant standardization process is still on-going. This is for further study and relevant contributions are invited. NGN-WG-004R1: Mr. Hyungsoo Kim (TTA) raised the issue of performance objective values for performance testing on CJK NGN test bed. Since CJK NGN test bed covers three countries, coordination between domestic and international performance objectives are necessary. TTA is planned to submit the enhanced version in a next meeting. This is for further study and relevant contributions are invited.
  5. 5. 10. Future meeting plan The next NGN-WG meeting will be held hosted by TTA in Korea, on 5th and 6th of February 2007. The next NGN-WG ad-hoc meeting will be held at ITU-T building in Geneva, from 13:00-17:00 on Sunday, October 22nd of 2006 chaired by Mr. Naotaka MORITA. The purpose of this ad-hoc meeting is to confirm the position of each country against candidate draft Recommendations targeting to complete at the NGN-GSI meeting. Another NGN-WG ad-hoc meeting will be held at ITU-T building in Geneva from 13:00 to 18:00 on Sunday, October 29th of 2006 chaired by Mr. Naotaka MORITA. The purpose of this ad-hoc meeting is to establish common and detailed technical views on the identified draft Recommendations given Annex B to this report. The next IPTV ad-hoc meeting will be held at Lotte hotel in Busan, Korea, from 16:00 to 18:00 on Sunday, October 15th of 2006 chaired by Ms. Duo Liu. 11. Closure of the meeting The chairman gave his thanks to all participants. Thanks a lot to contributors and the leaders on each group. And special thanks to TTC for its excellent local arrangements. -------------------
