6.1 Opening Plenary The Q.1/19 session was called to order at 9:00hrs on 6 September. The proposed agenda for the Q.1/19 plenary was approved. The terms of reference for this meeting are to continue the work as assigned to this question (former Q.1/SSG). All input documents assigned to Q.1/19 discussion were distributed to work items as shown in Temporary Document TD-218R1.

6.2 General Items (TD 115, 117, 181, 184, 187, 188, 189, 192, 193, 194, 195, 215, 218) The following provides a brief summary of the discussions on and dispositions of input documents that were assigned to the work item “General Items.” TD-115 (Response to SG19 Liaison Statement on Trial of Public Access to SG 19 Documentation) – TSAG endorses the Study Group 19 proposal in its liaison statement on “Trial of Public Access to SG19 Documentation” with a number of amendments. TSAG agrees that how to proceed further can be decided at the end of 2006. TSAG looks forward to hearing reports, which include subjective aspects, regarding the effectiveness of this trial from Study Group 19. noted. TD-117 (LS to ITU-T Study Groups on work on Telecommunications for Disaster Relief and Early Warning and an Action Plan) – TSAG D.9 proposed that more technical standards could be created in support of Telecommunications for Disaster Relief (TDR) and Early Warning (EW). The Action Plan as agreed at TSAG in its meeting 14-18 March 2005 is attached. TSAG encourages all Study Groups to review their work programme for work in TDR/EW, as applicable and to provide TSAG and Study Group 2 with a feedback. noted. - 4 - TD 236 R1 PUBLIC (GEN/19)

TD-181 (Project Co-ordination and Release Planning for NGN) – Study Group 13 continues to work on an interactive ITU-T Web site for NGN and to request each Study Group to provide details of its existing Recommendations or Recommendations under development that would fit within the scope of NGN. Study Group 13 also requests that each Study Group provide a single contact point for NGN Release planning. In the discussion the group pointed out that Q.1702 and Q.1703 could be relevant. But the group also pointed out that this information has already been sent to Study Group 13 by TD120 as a reply to the same request from Study Group 13 and agreed that any further liaison statement is not needed at this moment. TD-184 (Liaison statement on the first OCAF Focus Group deliverable, Carrier Grade Open Environment (CGOE) reference model) – The objective of the Open Communications Architecture Forum (OCAF) Focus Group under the Study Group 13 is to agree on specifications for a set of components for a new carrier grade open platform that will accelerate deployment of NGN infrastructure and services. Regarding its first deliverable “Carrier Grade Open Environment (CGOE) reference model,” Study Groups are invited to comment, propose for enhancement, or indicate interest. noted. TD-187 (Response to liaison on general security policy for secure mobile end-to-end data communication) – Q.9/17 explains X.msec3 further in response to the liaison from Study Group 19. X.msec3 focuses on mobile environment and can support NGN evolution, since for value added security service, conceptions and key techniques in X.msec3 can be applied to both fixed and mobile environment. noted. TD-188 (Report of the 7th FGNGN meeting) – The 7th FGNGN meeting report and the current draft of the NGN Release 1 scope document are attached for information. The Q.1 acting rapporteur pointed out that this temporary document is obsolete because TD 215 is now available. noted. TD-189 (Outputs from the 7th ITU-T NGN Focus Group meeting) – The NGN Release 1 scope document and the NGN Release 1 requirement document as of the end of the 7th FGNGN meeting are attached. FGNGN acknowledges the lead role of Study Group 19 in harmonizing mobility related concepts and terminology with other parts of the ITU-T and requests guidance from Study Group 19 on mobility related issues. noted. TD-192 (Reply to LS on Work on Telecommunications for Disaster Relief and Early Warning and an Action Plan) – In response to the request from TSAG that all ITU-T Study Groups are expected to increase their activities for TDR and EW and that an ITU-T Action Plan for TDR and EW is to be established, Study Group 16 provides TSAG and SG2 with a first feedback on the actions taken and improvements suggested to the Action Plan. The current possible contribution to the Action Plan from Study Group 16 is attached. noted. TD-193 (LS on Multimedia Service Mobility) – This liaison statement from Study Group 16 informs that Q.29/16 has started work on requirements with regard to the deployment of Multimedia Service mobility within NGN. Study Group 16 requests Q.2/19, Q.5/19, and Q.6/13 to give a feedback to Q.29/16 and to give its view about a common implementation of this issue. noted. TD-194 (LS on V.15x-series applicability to PSTN/ISDN emulation/simulation services) – Q.11/16 has developed Recommendations that address the transport of voice band modems over IP networks. Q.11/16 requests that, in the definition of access and PSTN/ISDN emulation/simulation services in the NGN, Recommendations V.150.1, V.151, V.152 and T.38 (for facsimile) be considered. noted. TD-195 (LS on ISUP/BICC enhancement for VED) – Q.16/16 is currently defining a “VED for mobile networks”. ISUP/BICC should be enhanced to carry VED related information. On the other hand, a contribution describing the relevant coding and procedures has been presented to Q.3/11, - 5 - TD 236 R1 PUBLIC (GEN/19) but has been put on hold waiting for Study Group 19, as the lead group for mobile, for the support of this work. Q.18/16 asks Study Group 19 to confirm the need to enhance ISUP/BICC to carry VED related information. NTT DoCoMo commented that since Q.1 is now discussing network architecture, that Q.1 is not in a relevant position to comment on this topic. NTT DoCoMo further commented that this enhancement has possible impacts on existing systems and that it needs to be carefully handled by Q.3 where experts of 3GPP/3GPP2 are working. TD-215 (Report of the 8th FGNGN meeting) – The 8th FGNGN meeting report and the current draft of the NGN Release 1 scope document are attached for information. Since no comments were raised from the floor, the Q.1 acting rapporteur requested participants to take time and to look through the documents. The document was revisited afterwards, but no comments were raised. noted. TD-218 (Draft agenda for Q.1/19) – This temporary document is a draft agenda for Q.1/19. TD 218 was revised into TD 218R1 by adding three documents to be handled. The group reviewed and agreed to TD 218R1.

6.3 Functional Network Architecture for Systems Beyond IMT-2000 (Q.FNAB) (D 23; TD 217) Based on input contributions and discussions at the meeting, Q.FNAB version 4.0 (Revision 1) was developed and made available as TD 217R2. The Q.FNAB version 4.0 (Revision 1) is based on the Q.FNAB version 3.0 (TD 217) and the modifications proposed by Delayed Contribution 23 (D-23) and the comments received during the sessions of Q.1/19. The following provides a brief summary of the discussions on and dispositions of input documents that were assigned to the work item “Q.FNAB”. D-23 (Network function for Q.FNAB) – This delayed contribution is from Korea. < Discussion notes are in the version of this document behind TIES.> TD-217 (Draft Recommendation Q.FNAB (version 3.0)) – This temporary document is the latest version of Q.FNAB, which is the output from the last Study Group 19 meeting during 3-6 May 2005 and which was used as the base text for the current Q.1/19 sessions. After discussion of D 23, the Q.FNAB version 4.0 (TD217R1) was drafted. This was further reviewed and the Q.FNAB version 4.0 (Revision 1) (TD217R2) was drafted including comments that would clarify issues to be solved. The Q.FNAB version 4.0 (Revision 1) (TD217R2) was reviewed and agreed to.

6.4 Review of Work Plan for Planned Deliverables Based on the comments received during the Q.1/19 meeting, Stage 2 Recommendation Q.FNAB (Functional network architecture for systems beyond IMT 2000), version 4.0 (Revision 1), was developed. It was agreed that one electronic meeting should be held to progress the work on Q.FNAB before the next SG 19 Meeting. The planned Q.1/19 Rapporteur’s Electronic Meeting is scheduled for 8-22 November 2005. And besides it was agreed that the timing for Q.FNAB should be 3Q2006 instead of 4Q2005 due to the lack of maturity of the current Q.FNAB. The group pointed out that elements of Q.FNAB, including the whole architecture, security functionalities, or service platform functionalities are still missing and commented that Q.FNAB needs to be revisited to consider consistency with NGN work. The detailed work plan for Q.FNAB is provided in Annex 1. - 6 - TD 236 R1 PUBLIC (GEN/19)

6.5 Closing Plenary of Q.1/SSG Q.1/19 held its closing plenary at 9:00hrs on Thursday, 8 September 2005.
