The meeting was attended by about 11 delegates from 7 countries. The list of participants is provided in Annex 4. 1.2 Terms of Reference The Terms of References for this meeting as agreed in SG 19 and SG 13 closing plenaries in December 2004: Progress Mobility Management including in the context of FMC in conjunction with Q.6/13. 1.3 Meeting agenda The draft Meeting Agenda was published in Temporary Document 01. It was revised and approved as TD 01r1 and is reproduced in Annex 1 of this Report. 2 Key Results 2.1 Work Items Progressed Mobility Management Terms were discussed in details and several Terms were harmonized across Questions from various ITU-T SGs. (Additional results are included in the version behind TIES.) 3 Meeting Documentation Documents considered at this meeting are listed in Annex 3. All documents are available at http://ties.itu.int/u/tsg19/sg19/xchange/q2/0503Melbourne/. 4 Liaison Statements The meeting resulted in the preparation and approval of Liaison Statements as summarized in Table 1. Table 1 – Outgoing Liaison Statements Addressee ITU-T SG13 5 Document number TD 13 <body> Question Q.2/19, Q.5/19, Q.6/13 For Title/ Subject information Reply to the LS on Project coordination and release planning for NGN Detailed report of discussions TDs 06 and 07 are to be kept behind TIES at the authors request. -3TD 14r1 TD 01 – Agenda and Work Plan. Approved as TDr1. TD 02 – Project co-ordination and release planning for NGN Noted. SG 13 to manage/coordinate but should take advantage of expertise in all SGs. Concern with time schedule. Any release that does not include clear implementation plans (e.g., Stage 3) by the vendors may not be justified. We should not duplicate the work of SDOs. The reply from SG 19 should include our mandate and references to Q.1741/1742. Operators are very interested in FMC. What does “an interactive ITU-T Web site” mean? An LS reply is drafted in TD 14. TD 03 - Some relative documents from the latest SG13 and NGN-FG meeting This is a compilation of MM related documents from SG 13 and NGN-FG. The group used this TD and relevant contributions and email exchanges to agree on the following terminologies: General Mobility: the ability for the user to communicate and access services irrespective of changes of the location or technical environment such as the Access Network capabilities, with or without service continuity. Terminal Mobility: Terminal Mobility is defined as the terminal having the ability to be moved to different physical locations and provide the user access to their services. Personal Mobility: The ability of a user to access services independent of the terminal or the location of the terminal. Service Continuity: The ability for a user to maintain an ongoing service during Generalized Mobility. Nomadism: The ability of the user to access services when the user moves from terminal to terminal or the user moves a terminal from one location to another location and the Network(s) is(are) unable to maintain the user’s service (session?). Roaming: The group agreed that this terms does not need to be define or used in the context of NGN because Nomadicity covers the relevant concept in NGN. TD 04 - Mobility between H.323 multimedia systems and GPRS/IMT2000 networks (Rev 2.0) H.323 acts as an application on the top of SIP in IMS. The document needs to reflect the access independent nature of IMS. Mobility Management definitions will be replaced by a pointer to the relevant documents in ITU-T. -4TD 14r1 It was not clear if H.323 application requires additional security beyond what is already available by IMS. TD 05 - Possible Extensions to Mobility Definitions in H.323 Systems with regard to NGN and System Convergence A very useful compilation of MM definitions in various ITU-T documents. This document was used as one of the inputs to the terminology discussion. TD 06 - Use of IMS as the Basis for FMC in NGN (Discussion notes are in the version of this document behind TIES.) TD 07 - Use of Subscriber Identity Module (SIM) functionality in FMCed NGNs (Discussion notes are in the version of this document behind TIES.) TD 08 - RFC 3753 - Mobility Related Terminology It was noted that the MM terminologies used in IETF is primarily from the IP point of view and they may have significant differences to those being discussed in NGN or IMT2000. TD 09 - Technical Report on NNI Mobility Management Requirements for Systems Beyond IMT-2000 No contributions to this carry over document so it was not treated. TD 10 - Mobility Management Framework for Systems Beyond IMT-2000 No contributions to this carry over document so it was not treated. TD 11 - Baseline Document for 2nd stage deliverable for Q.5/19 on “FMC Network Architecture and interfaces” No contributions to this carry over document so it was not treated. TD 12 - Proposal for review of classification and definition of mobility A late TD. The group agreed to allow it for inclusion. TD 12 stimulated a very useful discussion. Points of agreement from the discussion were: - Tree Diagrams such as in the current FG NGN documentation and in TD 12 have positive and negative aspects: the discussion noted that trying to resolve this area through defining or refining such a diagram may not be the best approach - An approach using scenarios (e.g., a user walking down the street, a user driving in a car, a group of users on a train or plane, etc.) should be the starting point - Within the scenarios identified, a criterion for further investigation of a scenario should be whether network actions are required to maintain the scenario (e.g., when using a given access means, a moving user may require handover, while a stationary user would not; a stationary user may need to change access means as a result of a change in the service desired or for some other reason; etc.) -5TD 14r1 Although no conclusions were reached, the above points were considered a suitable methodology to further develop this area. As a stimulus to further progress in this area and to capture points raised in the discussions, some notes are attached as Annex 5 to stimulate contributions. TD 13 - Reply to the LS on Project coordination and release planning for NGN Drafted during discussion and forwardes to SG 19 Chair for review and approval by correspondence. Please see TD 02 for additional discussion. 5.1 Review of Meeting Report.
