1. General 1.1 The third meeting of ITU-T Study Group 19 “Mobile Telecommunication Networks” in the 2005-2008 study period, took place in Geneva, Switzerland, in the ITU Facilities from 5-9 September 2005. The meeting was convened by TSB Collective Letter 3/19 dated 3 June 2005 and was chaired by Mr John Visser (Nortel, Canada), assisted by the following SG 19 Vice-Chairmen: Mr Maurice Ghazal (MPT, Lebanon) Mr Motoshi Tamura (NTT DoCoMo, Japan) 1.2 Two Vice-Chairmen were not able to participate in this meeting, extended apologies for their absence, and designated representatives to take their places: Mr Young Kyun Kim (Samsung Electronics, Korea) represented by Mr Kees den Hollander Mr Patrick Masambu (Communications Commission, Uganda), represented by Mr Patrick Mwesigwa 1.3 Three Vice-Chairmen were not able to participate in this meeting and extended apologies for their absence: Mr Kiritkumar Lathia (Siemens Mobile Communications, Italy) Mr Bruno Ramos (ANATEL, Brazil) Mr Konstantin Trofimov (NIIR, Russia) 1.4 The Chairman opened the meeting at 09:30 on 5 September 2005 and welcomed the participants. The Chairman invited Dr Houlin Zhao, ITU TSB Director, to provide some opening remarks. Dr Zhao gave a warm welcome to the delegates, and then noted a number of points: The GSC-10 meeting which took place in Sofia Antipolis, 28 August - 2 September produced a Resolution on IMT-2000 and beyond1 which explicitly recognized the role of ITU-T SG 19 in studying systems beyond IMT-2000. Three study groups meeting in parallel per the discussions at WTSA-2004 provide a good opportunity for experts to come together to advance the work on Next Generation Networks. A new name for this collective effort is being sought. Co-located Rapporteurs’ meetings addressing NGN matters will be announced by Collective Letter to raise the profile of these meetings. The Chairmen of Study Groups 12 and 16 have indicated willingness to have relevant Rapporteurs’ meetings from their Study Groups co-located and included in these Collective Letters. The overall goal is to maintain the momentum of the NGN work as it transitions into the regular Study Group structure. The TSB is planning to publish a “book” of the FG NGN output documents to capture in one place what has been achieved, and what is planned. These and other methods are aimed at dispelling any misperception that the work will be slowing down as a result of this transition. An issue is noted on the SG 19 agenda with respect to continuing the NG studies on fixed- mobile convergence and mobility. It is natural that SG 19 should take care of this. He noted that SG 19 is working quite well although it is not that big: major companies are still active and experts from companies are able to work calmly. He encouraged more attention be paid to case studies to show examples and principles of the application and evolution of IMT-2000 networks, in conjunction with the BDT as

ITU-T\COM-T\COM19\R\R3E-PUBLIC.DOC - 5 - COM 19 – R 3 PUBLIC – E
appropriate, noting that Africa and India, as two examples, are experiencing very high growth rates in mobile subscriptions. He noted that not only mobile but also fixed-mobile convergence will have significant economic and social effects on the world. 1.5 The SG 19 Chairman provided his opening remarks and stated his overall objectives for the meeting. These are summarized here: SG 19 should discuss its situation and should decide to assert its mandate per WTSA-2004. In order to put some substance behind asserting its mandate, SG 19 should be prepared, at this meeting, to conduct a thorough review of all FG NGN draft output documents that contain mobility or fixed-mobile convergence material, and should provide detailed and specific comments as feedback to the next meeting of the FG NGN in November. Draft new Recommendation Q.1741.4 should be finalized and offered to the closing plenary for Consent. All deliverables identified in the Work Programme should be progressed as much as possible in accordance with input material available.
2. Documentation for the meeting 2.1 The agenda, as provided in Collective Letter 3/19, is available as TD 177 and has been attached to this report as Annex 1. It was accepted as proposed. 2.2 The meeting considered twelve contributions (D-17 through D-28.) The meeting considered fourteen liaison statements, listed in TD 198R3. One series of Temporary Documents was assigned. A proposed document allocation was made available as TD 210. TDs generated during the meeting are not included in this allocation. 2.3 The list of participants was distributed as TD 242. 2.4 All documents for the meeting may be downloaded from the SG 19 web page: http://www.itu.int/ITU-T/studygroups/com19/index.asp.
3. Approval of Draft Recommendation
3.1 AAP Consent of Draft New Recommendation 3.1.1 A draft new Recommendation entitled “IMT 2000 References to Release 6 of GSM evolved UMTS Core Network” was proposed for AAP Consent at the closing plenary. It was confirmed that the requirements of Recommendation A.5 with respect to referencing documents of external organizations were met: details are found in §6.2 of TD 230R1. A question to the plenary on patent information related to the candidate draft Recommendation elicited no response. TD 222 lists editorial work required to complete preparation of the draft new Recommendation for the AAP process. The following Recommendation has therefore been consented for AAP. The Q-series number allocated to this Recommendation is Q.1741.4.

ITU-T\COM-T\COM19\R\R3E-PUBLIC.DOC - 6 - COM 19 – R 3 PUBLIC – E
3.2 Translation of Text of New Recommendation 3.2.1 The meeting considered the matter of how best to translate the text of newly AAP Consented Recommendation to ensure that the results would be useful and meaningful to those using other language versions while minimizing the amount of translation effort required. SG 19 recommends that the entire contents of Recommendations in the Q.174x.y series should be translated with the following exceptions: • Translation of the titles of references that exist in English only should not be done. • Translation of the tables should not be done. • Translation of the list of acronyms and abbreviations should be handled in a special way. Since acronyms and abbreviations often do not translate well, all language versions should include both the English as well as the translated list of acronyms and abbreviations in order to provide a common reference point for all readers. 3.2.2 It is estimated that the above approach may save some of the translation effort that would otherwise be required with no loss of value to the users of these Recommendations. It is suggested to the TSB that it considers proceeding accordingly.
4 Next Generation Networks and SG 19’s Role 4.1 The report and selected draft output documents of the seventh meeting of the Next Generation Networks Focus Group (Beijing, China, 27 June – 1 July 2005) are found in TD 188 and TD 189. The list of meeting report documents and current output documents for the eighth meeting of the FG NGN (Geneva, 24 August - 2 September 2005) was provided in TD 213. The report of the eighth meeting and the draft output document “NGN Release 1 – Scope” are found in TD 215. 4.2 The meeting discussed the need for SG 19 to assert its position on its role in NGN studies, especially with respect to mobility and fixed-mobile convergence. TD 211 provides a “Proposed statement on SG 19's role in NGN studies” drafted by the SG 19 Management Team. This statement was endorsed as proposed (the UK expressed a reservation) for input to the NGN-JCA meeting on 6 September where it is available as JCA document 13. This statement is attached as Annex 3. 4.3 The summary report of the JCA is available as TD 239 and reflects essential points from the SG 19 position statement. 4.4 Three contributions from Canada, D 24, D 25 and D 26 indicated the necessity for SG 19 to review the FG NGN deliverables to identify mobility and fixed-mobile convergence documents, or sections thereof, to conduct a thorough review, and to provide feedback to the FG NGN accordingly. The meeting agreed that the indicated Rapporteurs be instructed to do this.
5. Reports of Interim and Related Activities 5.1 TD 199 provides the report of the Q.2/19 e-meeting of 14 – 22 June 2005. TD 200 provides the report of the Q.2/19 e-meeting of 4 – 11 July 2005. The results of these e-meetings will be used as input to the discussions under Q.2/19 at this meeting. The planned Q.1/19 e-meeting was cancelled due to insufficient input documents. The Q.5/19 e-meeting was brought to a close part way through due to lack of interaction on the electronic forum. 5.2 One liaison statement had been reviewed and approved by correspondence since the last SG 19 meeting, and was endorsed: TD 183 is a liaison statement sent to ITU-R WP 8F “Executive summary on 2nd ITU-T SG 19 meeting (Geneva, 3 – 6 May 2005)” to provide information per the title.

5.3 Notes on the discussions on the remaining general documents identified in the opening plenary may be found in Annex 2.
5.4 Open Access to SG 19 Documentation 5.4.1 The SG 19 Chairman is to report to TSAG on SG 19’s experience to date with respect to the conduct of a trial of making SG 19 documents publicly accessible. It is noted that three contributions and a number of TDs to this meeting were designated for public access. A public version of the previous meeting’s formal report has also been available for some time, together with a number of Rapporteurs’ meeting reports. 5.4.2 No issues or concerns of any sort have arisen as a result of the open and public access to these documents to date. The SG 19 Chairman will so indicate to TSAG at the upcoming meeting, 7 - 11 November 2005, unless circumstances change. 5.4.3 The SG 19 Chairman encouraged participants to continue to strive for greater openness and public accessibility for their documents within the agreed guidelines in order to obtain the fullest possible experience in this area.
6 Study Group Structure, Appointment of Rapporteurs and Meeting Timetable 6.1 Due to the unavoidable absence of Mr Bruno Ramos, Mr Atsushi Minokuchi volunteered to handle Q.1/19 for this meeting. This was agreed. 6.2 Due to the unavoidable absence of Mr Farrokh Khatibi, Mr Kees den Hollander volunteered to act as Rapporteur for Q.2/19 as well as Q.5/19 at this meeting.

7. Approval of reports of individual Questions
7.1 Q.1/19 “Service and network capability requirements and network architecture” 7.1.1 The meeting reviewed and approved the report of Q1/19 in TD 236R1, attached as Annex 5. A public version of TD 236R1 has also been posted. 7.1.2 The key result extracted from the report of Q1/19 is: Developed the draft of the ITU-T PDNR: Functional Network Architecture for Systems Beyond IMT-2000, Q.FNAB, version 4.0 (Revision 1) (TD 217R2). Reviewed, and agreed to the Work Programme for Q.1/19 that has changed the timing for Q.FNAB from 4Q2005 to 3Q2006. 7.1.3 Q.1/19 proposed no outgoing liaison statements. 7.1.4 The agreed schedule of interim activities is included in §9 below.
7.2 Joint Q.2/19 “Mobility management” and Q.5 “Convergence of evolving IMT-2000 networks with evolving fixed networks” 7.2.1 The meeting reviewed and approved the report of the joint meetings of Q.2 and 5/19 in TD 235R2, attached as Annex 6. 7.2.2 Key results extracted from the report of the joint meeting of Q.2 and 5/19 are: Draft Q.MMR (Mobility Management Requirements; TD 232R1) was enhanced in the areas of mobility management features and the requirements for inter-CN and
ITU-T\COM-T\COM19\R\R3E-PUBLIC.DOC - 9 - COM 19 – R 3 PUBLIC – E
inter- and intra-AN mobility management. A requirement was added on support of private IP address domains. Mobility definitions have been harmonized with Q.6/13. Draft Q.MMF (Framework for Mobility Management; TD 233R1) was enhanced in the areas of Location Update, Registration, Query and Reply. A new section was added on Paging Management. Draft Q.FMC stage 2 (IMS-based Fixed Mobile Convergence; TD 234R1) was extended with new sections on high level principles and support for Voice Call Continuity. An annex was added that provides an Enterprise Role Model as the basis for identification of the prime inter-domain interfaces for FMC. The scope section was updated to better reflect the intent of the recommendation to identify and refer to suitable inter-domain interface specifications for IMS based FMC. The mobility management and FMC related sections of the eighth FG NGN meeting output documents were reviewed. A liaison response to the FG NGN was prepared. After the discussion in the JRG of Q.6/13, Q.2/19, Q.5/19 on the allocation of FG NGN deliverables (see TD 225R2) the joint Q.2 and 5/19 meeting confirmed its view that FRMOB (Mobility Management Capability Requirements for NGN) and IFN (IMS for NGN) fall wholly within the mandates of Q.2 and 5/19, respectively. The UK expressed a reservation on the conclusion reached by the joint Q.2 and 5/19 meeting for the named Focus Group deliverables that they fell wholly within the mandates of Q.2 and 5/19, in that this does not reflect the scope and content of these documents. 7.2.3 The joint meeting of Q.2 and 5/19 proposed one outgoing liaison statement as noted in §10. 7.2.4 No interim activities are presently scheduled.
7.3 Q.3/19 “Identification of existing and evolving IMT-2000 systems” 7.3.1 The meeting reviewed and approved the report of Q.3/19 in TD 230R1, attached as Annex 7. 7.3.2 The key result extracted from the report of Q.3/19 is: Reviewed and approved inputs of TTA for Recommendation Q.1741.4 and prepared this Recommendation for Consent. FG NGN output document 224 draft FG NGN/IFM (IMS for Next Generation Networks) was reviewed and is considered to be progressing appropriately. 7.3.3 Q.3/19 proposed one outgoing liaison statement as noted in §10. 7.3.4 No interim activities are presently scheduled.
7.4 Q.4/19 “Preparation of a handbook on IMT-2000” 7.4.1 The meeting reviewed and approved the report of Q.4/19 in TD 229, attached as Annex 8. 7.4.2 The key result extracted from the report of Q.4/19 is: A new chapter on emergency communications was reviewed and adopted by the meeting participants for the inclusion into the second Edition of Handbook on IMT- 2000. 7.4.3 Q.4/19 proposed one outgoing liaison statement as noted in §10. 7.4.4 No interim activities are presently scheduled.
ITU-T\COM-T\COM19\R\R3E-PUBLIC.DOC - 10 - COM 19 – R 3 PUBLIC – E
7.4.5 The Rapporteur made a plea for measures to be taken to further encourage the involvement of developing countries and countries with economies in transition in the work on Handbooks. Input on the needs of such countries that can be addressed by the work on Handbooks has the potential to be particularly beneficial in stimulating input.
7.5 Joint meeting of Q.6/13 “NGN mobility and fixed-mobile convergence” plus Q.2/19 “Mobility management” and Q.5/19 “Convergence of evolving IMT-2000 networks with evolving fixed networks” 7.5.1 The meeting reviewed and approved the report of Q.5/19 in TD 225R2, attached as Annex 9. 7.5.2 Key results extracted from the report of Q.5/19 are: The meeting agreed there is no essential difference from a network perspective between the long term objectives of the NGN and SBI2K frameworks with regard to Mobility Management. FMC is an important aspect of both frameworks. The meeting agreed that the FG NGN deliverable on NGN Functional Requirements and Architecture (FRA) provides an overarching framework for NGN and should be elaborated in association with Q.6/13 and Q.2/19 and Q.5/19. There was a lot of support from Q.2/19 and Q.5/19 experts for the view that the FG NGN deliverables on mobility (FRMOB) and IMS for Next Generation Networks (IFN) are pertinent to the Q.2/19 deliverables on Mobility Management and Q.5/19 deliverable on IMS-based FMC respectively. Q.6/13 experts were of the opinion that it was out of scope for the current meeting to agree on a recommending an allocation of these deliverables, and proposed to leave it to the JCA and coordination between SGs. 7.5.3 The joint meeting of Q.6/13, Q.2/19 and Q.5/19 proposed no outgoing liaison statements. 7.5.4 No interim activities are presently scheduled.
8. Allocation of NGN deliverable responsibilities 8.1 TD 238 provided the most recent version available of the proposed allocation of FG NGN deliverables into the regular study group structure. SG 19 noted that deliverables FRMOB and IFN (see §§7.2.2 and 7.5.2 above) are marked as “still under review” with respect to which study group, 13 or 19, should be the approving study group. The SG 19 Chairman was given the mandate to take the SG 19 position into the SG 13 closing plenary that these two deliverables fall within the purview of SG 19 per WTSA-2004 discussions and decisions as captured in WTSA document 118 and Resolution 2 (the UK expressed a reservation on this and asked that this be indicated by the SG 19 Chairman when he raises this in the SG 13 plenary), and as “endorsed by a meeting between the TSB Director and Heads of Delegation on 7 September and form the basis of the ongoing coordination, planning and management of the NGN work.” (TD 240)
9. Future meetings 9.1 The next meeting of SG 19 is scheduled to take place 23-27 January 2006 in Geneva per TSB Circular 40 dated 25 July 2005, during the same period as SGs 13 and 11. Further details will be provided by Collective Letter and will be posted on the SG 19 web site in the usual manner. At this time, specific time allocations to Questions, including which Questions across which study groups should meet together, were not available. The meeting agreed that the SG 19 Chairman should take the position in the SG 13 closing plenary that this was an urgent area to be sorted out,
ITU-T\COM-T\COM19\R\R3E-PUBLIC.DOC - 11 - COM 19 – R 3 PUBLIC – E and that it should be addressed through correspondence amongst the leadership of the involved study groups with the aim of having an agreed arrangement in place no later than the start of the TSAG meeting, 7 - 11 November, 2005, and taking due account of the potential for conflicts with other important meetings that are taking place around the same time. Further specifics will be developed in consultation with the Rapporteurs. 9.2 The SG 19 Meeting Schedule Coordinator, Mr Motoshi Tamura, presented TD 201R1 which provides information on the schedule for selected meetings of other groups relevant to the SG. This provides an excellent overview of meetings of interest to SG 19 and will also be used by the SG leadership and Rapporteurs in planning meeting schedules as noted above. An update reflecting SG electronic meetings and Rapporteurs’ meetings, etc., will be provided after the meeting as TD 201R2. Mr Tamura’s efforts are much appreciated. 9.3 Subject to adjustments per the anticipated correspondence activity indicated above, it is anticipated that the overall SG 19 meeting schedule for the 23-27 January 2006 meeting will be similar to that used at the current meeting. SG 11 meets the same week. The SG 19 Chairman will work with the SG 11 Chairman to avoid overlapping plenaries. The SG 11, 13 and 19 Chairmen have agreed to run their closing plenaries sequentially on 27 January. These measures should assist smaller delegations in tracking the activities of the three study groups meeting in parallel. 9.4 Interim meetings were proposed and approved as listed below. Electronic meetings will take place using the electronic discussion board facilities at http://forum.itu.int/jive/index.jspa? categoryID=2 supplemented by meeting document access on TIES. Guidelines for the conduct of electronic meetings may be found at http://www.itu.int/ITU-T/studygroups/templates/index.html. • Q1/19: • Electronic: 8 - 22 November 2005 • Terms of Reference: to progress the work on Q.FNAB 9.5 Information on the arrangements for the above meeting will be made available on the ITU-T SG 19 web page: http://www.itu.int/ITU-T/studygroups/com19/index.asp. Rapporteurs are encouraged to send out reminders as they approach the dates for their meetings. The TSB will only post information about the above meetings as provided by the Rapporteurs.
10. Approval of outgoing liaison statements 10.1 The following table provides a list of the liaison statements that were proposed. All the listed Liaison Statements were reviewed and approved during the presentation of the individual Question reports except as noted in §10.2. The work of Mr Tamura in Mr Masambu’s absence in coordinating these liaison statements is much appreciated. 10.2 In TD 112, received at the previous SG 19 meeting, TSAG requested that study groups provide information on tracking outgoing LSs to non-ITU-T organizations. A report to TSAG on this is provided in TD 241, included in the table below.

Annex 3 - SG 19’s Position on its Role in NGN Studies Introduction SG 19’s view on its mandate, on the handling of the transition of mobility and fixed/mobile convergence studies, and on an approach to continuing to progress NGN studies is provided in this document. This text below was proposed to and agreed at the SG 19 opening plenary on 5 September. The UK expressed a reservation on this text. SG 19 Views on moving forward with NGN work Per WTSA-2004 Resolution 2, SG 19 is: “Responsible for studies relating to network aspects of mobile telecommunications networks, including International Mobile Telecommunications 2000 (IMT-2000) and beyond, wireless Internet, convergence of mobile and fixed networks, mobility management, mobile multimedia functions, internetworking, interoperability and enhancements to existing ITU-T Recommendation on IMT-2000.” WTSA-2004 designated SG 19 as the “Lead study group on mobile telecommunication networks and for mobility.” SG 19 is one of the study groups charged with Next Generation Network studies. WTSA Document 118 describes the relationships of relevant study groups to the work on NGN. On the basis of the mandates assigned and the decisions taken at WTSA-2004, it is clear that SG 19 has a central role in mobility management studies and in studies addressing the convergence of fixed and mobile networks. SG 19 supports the continuation of the NGN JCA to deal with the policy and administrative aspects associated with NGN studies. With the transition of the work of the FG NGN into the regular study groups, there is an opportunity to resolve issues in work allocation. SG 19 supports the continuation of a group with a mandate to maintain a record of NGN tasks and how they fit in the overall NGN view, and which will assist in scheduling joint meetings of Rapporteurs to progress the work efficiently and effectively. SG 19 recognizes the role of SG 13 wrt managing NGN studies and supports the work of Q.1/13 (Project coordination and release planning for NGN) in this regard. The Study Group ownership of each individual document should be clear from the onset and, as work progresses, there should be collective agreement on the assigned ownership of documents. Ownership must respect assigned mandates per WTSA-2004 Resolution 2. SG 19 supports holding co-located meetings of NGN-related Questions at about the same frequency as FG NGN meetings are presently held so that momentum can be maintained, and progress can be continued and perhaps accelerated. During regular Study Group meetings (co-located SGs 11, 13 and 19), individual Questions which meet between Study Group meetings should also meet to facilitate ongoing rapid progress, and ensure fairness and transparency so that the full membership will have opportunity to supervise, review, and consent the deliverables.

The agreed agenda for the Q.1/19 meeting is in Temporary Document TD 218R1. 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. 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 TD 120 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.1/19 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 to this liaison statement. 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 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 (Voice Enhancement Device) related information. On the other hand, a contribution describing the relevant coding and procedures has been presented to Q.3/11, 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.1/19 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.1/19 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.
ITU-T\COM-T\COM19\R\R3E-PUBLIC.DOC - 21 - COM 19 – R 3 PUBLIC – E
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 (TD 217R1) was drafted. This was further reviewed and the Q.FNAB version 4.0 (Revision 1) (TD 217R2) was drafted including comments that would clarify issues to be solved. The Q.FNAB version 4.0 (Revision 1) (TD 217R2) was reviewed and agreed to. 6.4 Review of Work Programme 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 Programme for Q.FNAB is provided in Annex 1 to TD 236R1. 6.5 Closing Plenary of Q.1/19 Q.1/19 held its closing plenary at 9:00hrs on Thursday, 8 September 2005. The Q.1/19 report, including all annexes, and the latest draft of ITU-T PDNR Q.FNAB version 4.0 (Revision 1) (TD 217R2) were reviewed and agreed to. The delegates were thanked for their participation in the Q.1/19 activities at this meeting. Q.1/19 discussion meeting was closed at 10:15 hrs. 6.6 Review of Meeting Report.

Annex 6 - Joint Report of Q.2/19 “Mobility management” and Q.5/19 “Convergence of evolving IMT-2000 networks with evolving fixed networks”
1. Organisation of the Meeting 1.1 Meeting Identification, Chairmanship and Participation The Q.2/19 and Q.5/19 Rapporteurs Group on ‘Mobility Management’ and ‘Convergence of evolving IMT-2000 networks with evolving fixed networks’ met jointly for a total of 7 quarter day session. The meeting was chaired by the Q.5/19 Rapporteur, Mr Kees den Hollander (Samsung Electronics). The meeting was conducted as a joint meeting of Q.2/19 and Q5/19, due to the inability of the Q.2/19 Rapporteur to attend this meeting of SG19. The meeting was attended by about 20 participants. 1.2 Meeting Agenda The approved meeting agenda was published in TD 214 and is reproduced in Annex 1 of TD 235R2.
2. Key Results The meeting achieved the following results: Draft Q.MMR (Mobility Management Requirements) was enhanced in the areas of mobility management features and the requirements for inter-CN and inter- and intra-AN mobility management. A requirement was added on support of private IP address domains. Mobility definitions have been harmonized with Q.6/13. Draft Q.MMF (Framework for Mobility Management) was enhanced in the areas of Location Update, Registration, Query and Reply. A new section was added on Paging Management. Draft Q.FMC stage 2 (IMS-based Fixed Mobile Convergence) was extended with new sections on high level principles and support for Voice Call Continuity. An annex was added that provides an Enterprise Role Model as the basis for identification of the prime inter-domain interfaces for FMC. The scope section was updated to better reflect the intent of the recommendation to identify and refer to suitable inter-domain interface specifications for IMS based FMC. The mobility management and FMC related sections of the 8th FGNGN meeting output documents were reviewed. The results are contained in TD 237, the liaison response to the FGNGN. After the discussion in the JRG of Q.6/13, Q.2/19, Q.5/19 on the allocation of FGNGN deliverables (see TD 225R2) the joint Q.2/19 and Q.5/19 meeting confirmed its view that FRMOB (Mobility Management Capability Requirements for NGN) and IFN (IMS for NGN) fall wholly within the mandates of Q.2/19 and Q.5/19 respectively.

TD 193 from SG16 that was assigned to Q.2/19 for action was discussed in the JRG meeting on Q2/19, Q5/19 and Q6/13 in the presence of the Q.29/16 Rapporteur. No further response liaison was required in his opinion. The results of the discussion can be found in TD 225R2. The review of the output documents of the 8th FGNGN meeting led to a liaison that is contained in TD 237R1.
5. Recommendation status and Work Programme The status and Work Programme for Recommendations and other deliverables under the responsibility of Q.2/19 and Q5/19 is summarized in Annex 2 of TD 235R2. The planned completion of Q.MMR and Q.MMF has been delayed to 3Q2006. Contributions on all deliverables are urgently requested to meet the scheduled dates. 5.1 Editors The editor of Q.FMC, Mr David McFarlane was unable to attend the meeting due to schedule conflicts. He does have the same problem for our next meeting. The Rapporteur for Q.5/19 has acted as editor for this meeting, but did call upon the Q.5/19 participants to consider taking on this task for our next meeting. 5.2 Future Work It was noted that it is desirable for Q.2/19 and Q.5/19 to continue to have joint meetings to discuss contributions and liaisons of common interest. This mode of operation is recommended for our next meeting. No interim meetings are proposed.
6. Detailed report of discussions 6.1. Opening of Joint Q.2 and 5/19 sessions The Q.5/19 Rapporteur, Mr Kees den Hollander, introduced himself to the Q.2/19 participants and thanked all delegates for their willingness to hold a joint meeting in the absence of the Q.2/19 Rapporteur. 6.2 Q.MMR D 21 from Korea is titled “Revised Draft Text of Q.MMR”. < Discussion notes are in the version of this document behind TIES.> D.28 (Korea Telecom) was directed at Q.MMF, but in the ensuing discussion it was agreed to incorporate the requirement to allow for use of private IP addresses in Q.MMR. During the review of Q.MMR it was noted that the following areas need further work: the requirement to support other forms of mobility than just terminal (MT) mobility is not yet reflected throughout the document requirements on MM to be able to take QoS constraints into account specific aspects of service mobility, such as requirements on the domains from where service may be delivered (home, visited network)
ITU-T\COM-T\COM19\R\R3E-PUBLIC.DOC - 25 - COM 19 – R 3 PUBLIC – E
This last point was brought out by TD 193 (Q.29/16). It was agreed to include appropriate editor’s notes into the next draft. Contributions on these subjects are requested. The agreed version 0.3 of Q.MMR as a result of the drafting activity during this meeting can be found in TD 232R1. 6.3 Q.MMF D.22 from Korea is titled “Draft new Recommendation Q.MMF (version 0.8)”. < Discussion notes are in the version of this document behind TIES.> D.20 from Korea has title “Paging Structure and Procedure for Q.MMF’. < Discussion notes are in the version of this document behind TIES.> D 28 (Korea Telecom) proposes to allow for use of private IP addresses and to reflect in section 5 of Q.MMF that an IP address itself may be used as a User ID. It was agreed to incorporate the first proposal as a requirement in Q.MMR and the proposed procedures in Annex A of Q.MMF on MIP. The second proposal was also accepted. During the review of Q.MMF it was noted that it also lacks a description of the support for other forms of mobility such as network mobility.

6 Detailed report of discussions The Delayed contribution D.27 “Draft new chapter for the Handbook on IMT-2000” is from Russian Federation. < Discussion notes are in the version of this document behind TIES.> TD 115 is a Liaison Statement from TSAG meeting (Geneva, 14-18 March 2005) on the trial of public access to some SG 19 documents. Q.4 received one Delayed contribution over the last two SG 19 meetings that was posted for public. This was noted by meting participants. No difficulties were identified with this document. TD 117 is a Liaison Statement from TSAG meeting (Geneva, 14-18 March 2005) informing the group about the Work on Telecommunications for Disaster Relief and Early Warning and an Action Plan and requesting reviewing the Work Programme, enhance existing Action Plan for standardization on TDR & EW; adapt it and send feedback to TSAG. The new Chapter on the emergency communications, reviewed and adopted by the meeting under the agenda item 3 as D 27, was considered an appropriate candidate for the inclusion into the list of SG 19 outputs of TDR and EW. TD 180 is a Liaison Statement from ITU-T SG 11 informing the group about SG 11 Action plan in support of developing countries and of countries with economies in transition. This document was for information. It was noted. The Rapporteur, seconded by the representative of Uganda, emphasised the importance of the representatives of developing countries to participate in the meetings and to contribute to the work, bringing their needs and requirements to the SG 19. TD 192 is a Liaison Statement from ITU-T SG16 informing the group about the SG16 action plan on work on TDR and EW. It was the response to the LS from TSAG as in TD 117. It was noted. TD 197 is a Liaison Statement from ITU-D Q.18/2 on guidelines for smooth transition of existing mobile networks to IMT-200 for developing countries. The Rapporteur pointed out with satisfaction the existing collaboration between the ITU-D Q.18/2 and Q.4/19. The coming workshop in Kyiv, Ukraine, is also a good example of correlation between Q.4/19 and ITU-D Q.18/2 work. Again the importance of the involvement of developing countries representatives was raised by the Rapporteur and the delegate from Uganda. The document was for information and it was noted by meeting participants. TD 207 is a Liaison Statement from ITU-R WP 8F to ITU-D SG 2 on proposed revisions to WTDC Resolution 43 “Assistance for implementing IMT-2000”. This document was reviewed paragraph by paragraph by the meeting and the group felt appropriate to propose the enhancements to the text of TD 207. A Liaison Statement was drafted as a result of the discussions at the meeting. It is found in TD 228 as well as in Annex 4 to TD 229. TD 179 is a SG19 Work Programme. The Q.4/19 portion of it was considered appropriate and no changes were introduced to it. TD 140 R1 is a chapter on fraud issues (for the second edition of the Handbook). It was approved at the last meeting of Q.4/19. The meeting took note of this document. During the discussion on any other business the Chairman, Mr Ghazal, proposed to urge Rapporteurs for Q.1, 2, 3 and 5/19 to send materials from their activities to Q.4/19 (Handbook) in order to start to develop different chapters for the inclusion into the second
ITU-T\COM-T\COM19\R\R3E-PUBLIC.DOC - 34 - COM 19 – R 3 PUBLIC – E
Edition of Handbook on IMT-2000. Mr Ghazal also was wondering if the activities of Q.3/13 and Q.6/13 should be introduced in the Handbook on the deployment of IMT-2000 systems.

Annex 9 - Report of Joint Meetings of Q.2/19 “Mobility management”, Q.5/19 “Convergence of evolving IMT-2000 networks with evolving fixed networks” and Q.6/13 “NGN mobility and fixed-mobile convergence”
1. Organization of Meeting This is the report of the Joint Rapporteurs’ Group meeting of Q.6/13, Q.2 and 5/19 that was held for three quarter day sessions on 5 and 7 September 2005. The meeting was chaired by Felix Zhang, Q.6/13 Rapporteur and Kees den Hollander, Q.5/19 Rapporteur. The latter was also representing the Q.2/19 Rapporteur who was unable to attend the meeting. The meeting agenda was published in TD 45 (WP2/13) and TD 216 (GEN/19). It is reproduced in Annex 1 to TD 225R2. The meeting was attended by about 35 participants.
2. Key results The meeting agreed there is no essential difference from a network perspective between the long term objectives of the NGN and SBI2K frameworks with regard to Mobility Management. FMC is an important aspect of both frameworks. The meeting agreed that the FGNGN deliverable on NGN Functional Requirements and Architecture (FRA) provides an overarching framework for NGN and should be elaborated in association with Q.6/13 and Q.2 and 5/19. There was a lot of support from Q.2 and 5/19 experts for the view that the FGNGN deliverables on mobility (FRMOB) and IMS for Next Generation Networks (IFN) are pertinent to the Q.2/19 deliverables on Mobility Management and Q.5 deliverable on IMS-based FMC respectively. Q.6/13 experts were of the opinion that it was out of scope for the current meeting to agree on a recommendation for the allocation of these deliverables, and proposed to leave it to the JCA and coordination between SGs.
3. Meeting documentation Documents considered at this meeting are listed in Annex 2 to TD 225R2.
4. Report of discussions 4.1 Introduction of FGNGN output documents The meeting considered the relevant sections of FGNGN-MR-00056, the FGNGN Chairman’s report of the last meeting held in Geneva (24 August – 2 September, 2005). With regard to the request to review NGN terminology, it was agreed to consider the mobility related terminology in detail during the Joint Q.2 and 5/19 meeting. The introduction of FGNGN-OD-00223 (NGN Functional Requirements and Architecture) raised the question if the Q.2/19 Mobility Management Framework (Q.MMF) can be easily mapped on FRA. It was confirmed that Q.MMF complies with the requirement for independence between Transport and Service Strata, but a detailed mapping on FRA functional entities needs further study. FGNGN-OD-00225 (Mobility Management Capability Requirements for NGN) was introduced.

< Discussion notes are in the version of this document behind TIES.> FGNGN-OD-00226 (Converged Service Framework) was introduced. < Discussion notes are in the version of this document behind TIES.> 4.2 Input material to Q.6/13 COM 13-D 231 was introduced. < Discussion notes are in the version of this document behind TIES.> 4.3 Liaison from Q.29/16 on Multimedia Service Mobility The Rapporteur for Q.29/16 was so kind to present TD 193 (GEN/SG19), a liaison from SG16 on Multimedia Service Mobility. < Discussion notes are in the version of this document behind TIES.> 4.4 Overview of Q.2/19 draft Recommendations on Mobility Management D 21, proposing new text for Q.MMR (Mobility Management Requirements for SBI2K), was introduced by the editor. < Discussion notes are in the version of this document behind TIES.> D 22, proposing new text for Q. MMF (Generic Framework of Mobility Management for SBI2K), was also introduced by the editor. < Discussion notes are in the version of this document behind TIES.> In the last session of this JRG meeting the acting Q.2/19 Rapporteur informed the meeting of the enhancements to Q.MMR and Q.MMF that were agreed at the meeting. 4.5 Overview of input material to Q.5/19 on Q.FMC stage 2 The baseline document from our last meeting (TD 159) reflects the agreement to limit the scope of Q.FMC stage 2 to IMS based networks that use ISIM functionality for user identification and authentication. The Rapporteur for Q.5/19 gave an overview of the contributions to this meeting to further the work on Q.FMC stage 2. This covers D.18, D.17 and D.19. < Discussion notes are in the version of this document behind TIES.> In the last session of this JRG meeting the Q.5/19 Rapporteur informed the meeting of the enhancements to Q.FMCstage2 that were agreed at the meeting. 4.6 Work allocation and plan Based on the review of the most relevant FGNGN draft deliverables on the one hand and the work in progress under Q.6/13, Q.2 and 5/19 on the other, the Q.5/19 Rapporteur explored the possibility to come to a consensus view on the most desirable allocation of the prime responsibility for these FGNGN deliverables. This based on the strong desire from SG19 from a process perspective to have the prime responsibility for each NGN deliverable assigned to a single question. It was agreed that it is critical to align the architecture work under our questions with the NGN framework architecture and that Q.6/13, Q.2 and 5/19 should therefore be associated with this work. Strong views were expressed by SG19 participants that Qs.2 and 5/19 would be the appropriate prime questions for the FRMOB and IFN documents respectively, also in light of the SG19 mandate. Q.6/13 participants were however of the opinion that the allocation of FGNGN deliverables is out of scope for a JRG meeting, and hence no consensus could be reached.
ITU-T\COM-T\COM19\R\R3E-PUBLIC.DOC - 37 - COM 19 – R 3 PUBLIC – E
All delegates shared the view that there is no essential difference from a network perspective between the long term objectives of the NGN and SBI2K frameworks from a Mobility Management perspective. FMC is an important aspect of both frameworks. For this reason it is desirable to continue with JRG meetings to co-ordinate the work and avoid overlap of work 4.7 Co-ordination of work at the January 2006 SG 13 and SG19 meeting The WP2/SG13 chairman informed the meeting that no decisions had been reached yet by the JCA on the allocation of FGNGN deliverables and co-ordination of work between NGN related Questions. It is therefore not possible to firm up plans for JRG meetings in January. Concerns were expressed about the current mode of operation, where JRG meetings do not have to reach agreements for the work under the participating Questions to proceed. The Q.5/19 Rapporteur expressed his preference for a JRG to have well defined deliverables that are progressed in JRG meetings and not anywhere else. The Rapporteurs will again request joint sessions of Q.6/13, Q.2 and 5/19 early on in the proceedings in order to have contributions of common interest reviewed only once. Detailed planning will have to wait until guidance is received on the organization of the work on NGN related questions.
