  1. Report on ETSI activities:1) NGN in ETSI2) Interconnection of Services Presenter: Ian Spiers Submission Date:July 13, 2008

  2. 1) NGN in ETSI NGN in TISPANCommon IMS in 3GPP Source: Rainer Muench, TISPAN Chairman

  3. 1) TISPAN is … the home of NGN standards • TISPAN is the ETSI body that • specifies standards for Fixed networks and internet convergence • developed the Convergence work Item (FMC) • specifies the Next Generation of Networks • Many of the participating organisations have their HQs from outside of Europe • TISPAN NGN specifications are referenced by the ITU-T • Common IMS parts of the TISPAN work are considered in 3GPP specifications as published by ETSI or other OPs • Open area: http://portal.etsi.org/docbox/TISPAN/Open • TISPAN NGN specifications can be considered as THE global NGN solution

  4. TISPAN is today • An important standards group (and a great one) … • Typically up to 160 participants per meeting • International participation (Europe, Asia, Americas) • Up to +800 documents to treat in 7 WGs during one week • 4 plenaries, 4-6 WG meetings, 4-8 ad hocs per year TISPAN IS GOOD

  5. TISPAN Organisation • 7 Working Groups • Requirements and Architecture • Protocols • Numbering, Naming, Addressing, Routeing • Home Networks • Testing and Validation • Security • Network Management • Hierarchical system for organising and managing the work • Oversee activity per topic • Collocated Technical Committee Plenaries and full WG meetings (4 times a year) • Interim meetings as required and agreed (face-to-face or virtual) • Close co-operation with other SDOs, ITU-T, 3GPP, corporate networks (e.g. Ecma), many fora and groups

  6. ETSI NGN Status • Release 1 ………….. Status Complete • Release 2 ………….. Nearing completion • Release 3…………… Requirement capture and early work progressing • Transfer of Work Items for Common IMS • All Common IMS related WIs have been transferred to 3GPP, TISPAN monitor progress carefully and take appropriate action if specific problems are identified.

  7. Some key work areas in NGN R2 • Resource control (RACS) • Network attachment subsystem (NASS) • Supplementary services • PSTN/ISDN Emulation (PES) • IPTV • TS 183 063 on IMS IPTV Stage 3 Core network aspects has been published. • TS 183 064 on IPTV dedicated system Stage 3 has been approved at TISPAN#18 Plenary (03 – 04 July 2008). • Numbering, naming, addressing, routeing • Home networks and devices • Corporate networks and business communication

  8. ETSI TISPAN NGN Release 3 • Early requirements for the next TISPAN Release include • VoIP Consolidation (including QoS, security, interworking) • IPTV Service evolution (blended services and beyond) • Consolidation of the work on business communication • Ultra Broadband (fixed and wireless) access to the NGN • Work progressing on Non-3GPP access systems • Improvements to Release 2, e.g. resource control • Interconnection (NGN, NGCN) • Network Harmonisation - increase interoperability with other NGNs and other networks (non IMS).

  9. Numbering, Naming and Addressing • TISPAN WG4 have investigated the need to introduce a Naming Address Resolution (NAR) framework into TISPAN NGN conformant communication networks • The following approach was adopted: • Investigation of ‘use cases in the NGN environment’ to determine required NAR functions • Gap Analysis of current TISPAN NGNs specifications - comparing them to existing/emerging solutions of NAR methods. • Identification of items requiring further standardization based on the above analysis • Analysis of the consequences of creating a Naming Address Resolution framework.

  10. NGN Interconnection • TISPAN is currently working on ENUM & DNS Guidelines that will enable TISPAN to evaluate their requirements against what is set out within the GSMA documents IR34 and IR37. • That exercise will provide a firm basis for TISPAN examine their requirements for an Inter-operator IP backbone network and discuss the possibility of a common approach with the GSMA, or alternatively conclude why this isn't the case. • ETSI to: • Complete work on ENUM & DNS Guidelines, NGN evolution for interconnection, inter-domain and access reference points, numbering, naming, addressing, routeing and Naming Address Resolution functionality • Identify any critical outstanding issues and propose a way forward, e.g. the need to develop further commercial and administrative arrangements required to facilitate the realisation of an IPX responding to TISPAN requirements • Compare detailed requirements and guidelines against other planned approaches e.g. GSMA • Consider the likelihood of achieving a viable large scale global approach for common IMS providers • ETSI is supporting the view that all required parties need to move forward in a coordinated manner. • ETSI is supporting collaboration with 3GPP, GSMA, SDOs, ITU-T.

  11. TISPAN NGN R2 security • NGN Security requirements (TS 187 001) • Defines also security requirements for IPTV, Business Communication, Media Security, Home Networking, and for countering UC • NGN eTVRA (TR 187 002) • Threat and risk analyses for specific NGN use cases such as NAT traversal, RACS, Media Security, and Unsolicited Communication; • NGN Security architecture (TS 187 003) • Defining the security architecture for IPTV, Home Networking, FMC, Media Security, H.248, Corporate Networks • Generalised NAT traversal feasibility study (TR 187 008) • Media security (TR 187 007) • Impact of unsolicited communication in the NGN (TR 187 009) • NGN Lawful Interception functional entities, information flow and reference points (TS 187 005) • Data retention and its impact on the NGN (TR 187 012)

  12. Early TISPAN NGN R3 security: • Feasibility study on IPTV security architecture • Study models and key management systems for service protection • aim to develop the model for the NGN. • Study of functional entities and mechanisms for service protection with the • aim to define these for the NGN. • Study of a framework open to the integration of content protection solutions. • Feasibility study of security mechanisms for customer premises networks connected to TISPAN NGN.

  13. Topics for future security work • IPTV security (enhancement of stage 2, definition of stage 3) • Adding Prevention of Unsolicited Communication as a feature (stage 1, stage 2, stage 3) • Identity protection, authentication and integrity countermeasures and to define credential management • Media security provisioning (stage 1, stage2) • Additional work on NAT-T (e.g. interaction with RACS, interaction with IPTV, security analysis of use of STUN) • Enhanced security for NASS, RACS • Security for CNG/CND (stage 1, stage 2, stage 3) • Implications for AGCF security • Security for NGCN • FMC (taking into account requirements of the FMCA) • Diameter and Radius AVP profiling • Application layer security on the NGN (e.g. TELCO 2.0) • Analyse the inter-relation between security features and architecture of the NGN (IPTV, NAT-T, NASS, RACS etc.) in terms of how to employ consistent security architecture and mechanisms • Develop general rules, patterns, and templates to ease the employment of the NGN in practice and to facilitate risk control

  14. Network Management • NGN Management • Resource Management (IMS Management imported from 3GPP) • Subscription Management (SuM) • IPTV Management • “JointSuM” • collaboration between ETSI TISPAN WG8, 3GPP SA5, and TM Forum TIP, working on alignment of the Subscription Management and Service Activation specifications in these bodies. Recently, also ITU-T SG 4 has indicated their interest in this work. • Collaboration • TM Forum and other de facto bodies are important players in the global telecom management standards arena. Their work is being taken into account in TISPAN WG8.

  15. Testing Activities • Production of manual and automatic test suites to ensure the conformance to TISPAN, 3GPP and ITU standardised protocols. • These tests ensure • the global interoperability for and between ISDN and TISPAN NGN Releases incl. PSTN/ISDN Emulation Subsystem, • QoS between networks, • performance benchmarking for NGN • Co-operation with • 3GPP • ITU (SG 11, SG 12)

  16. Next Steps (in Standards) • As NGN networks are being rolled out and tested, TISPAN is seeing a large increase in the number of corrections (CRs) to NGN-R1 and R2. This is a good sign. • TISPAN (and ETSI) recognises the importance of cooperation agreements and is identifying key bodies and works together to avoid duplication of effort. • TISPAN’s members are now focused on Rel-2 completion and progressing new work areas for Rel-3. • Push ahead with e.g. the Interconnection work, IPTV, home networks, next generation corporate networks, next generation access technologies.

  17. Other PSOs/Challenges • Noted that the work on NGN protocols in ITU-T SG 11 is progressing well. • It is noted that caution should be taken to ensure that work is not duplicated in PSOs. In general, cooperation with other PSOs is working well. • As new features and services are introduced using NGNs, more and more divers players are active on the playing field (e.g. NGN IPTV-Content suppliers-broadcaster etc). This has to be coordinated!

  18. 2) NGN Interconnection of Services NGN Interconnection of ServicesETSI Board Strategic Topic Source: Fernando Soriano Claudio Gentile

  19. Introduction • Within the topic of “Service level Interconnection of NGN Services” ETSI: • Intends to give a step forward and to highlight the importance of interconnection at the service level for Next Generation Network • Shows its determination to take the required steps to lead the creation of the interconnection standard • and wiliness to bring all parties together to collaborate in its realization • ETSI identified three main areas of work: • Need of Global Standard that covers IP interconnection of NGN services. • Avoiding divergent implementations • And assuring the global interconnection of NGN • NGN Interconnection of Services was approved as a strategic topic for 2008 by the General Assembly in November 2007

  20. Rationale • ETSI goal is the re-assure the elaboration of a global Standard for Interconnection of NGN Services. • Today interconnection of IP is optimized for Internet. • Interconnection of NGN services must take in consideration Telco requirements: • QoS across the whole chain • Payments, according to principles of initiating party pays (or others), premium numbers,… • Reduce complexity of interconnection among operators (and, potentially, thousands of players) to achievable targets • And this Interconnection has to be achieved at a global scale • Interconnection of NGN affects to a multiple players and organizations, and differences in their approaches may lead to duplication and divergence • Out of Scope: Commercial relation itself across the chain of IMS

  21. GAP Analysis • How identified requirements (business oriented) fit with current standardization work on interconnection? • Are well covered all aspects? • Are there overlapping among the work in technical organizations? • Initial study done by TE and TI • Taking as reference the IPX model developed in the GSMA • And the work under progress in 3GPP and ETSI TISPAN • Analyzing aspects related to: • Architectural models, network interfaces,… • QoS values defined across the IP chain (access, carrier, peering point, codecs,..), including KPI measurement, • Security: Define and manage different security levels and profiles • Consideration the intermediate figure of the carrier/hub • CDR specification and production within the technical infrastructure for settlements among participants • Testing to certify interconnection. • Etc. • Shows that technical work may need to be reviewed, prioritized and better synchronized.

  23. GAP Analysis: Architectures

  24. NGN Interconnection Workshop9 June 2008 - Discussion • Importance of IP interconnection growing at all levels • NGN operators, International Carriers, etc. • Regulators • Vendors • Presentations from the various organizations provided snapshots of activities • GSMA IPX model presented as major piece of requirements • IPI Alliance and i3 Forum recently established may provide additional requirements • 3GPP Rel 8 to cover • IMS to IMS NNI for direct interconnection • CS to CS based on SIP-I • More complex scenario’s including eg use of IPX service/network to be addressed in rel 9 • Discussion on the need to look at interconnection of IMS to generic (basic) SIP • Roaming support presentation from NTT DoCoMo. More activity to be done as it is expected to influence the evolution of interconnection • Presentation from TE and TI provided initial review of the gaps between the GSMA business requirements/models and the standards • Interoperability testing (eg in ETSI INT) will have increasing importance once the standards are finalized

  25. NGN Interconnection Workshop9 June 2008 - Output • Leverage TISPAN experience in this area to cover NGN requirements, not losing the expertise of this and other organizations • Need to be aware of developments also in other organizations including ITU and the regional SDOs partners of 3GPP and share ETSI findings also in GSC • It is proposed to develop a high level roadmap showing the programs of each organization and the critical relationships over time. This should possibly present the timescale relevant to the major requirements • What is the next step? Focus down on a specific case, on a service level NNI, which is critical to be put in place, to be standardized, and discuss that in detail as a next step • It was proposed to establish a mailing list to progress the discussion • Do not lose the momentum, don’t stop ongoing activities while looking at future improvement • It was supported the importance of seeking a coherent and coordinated set of standards with global value

  26. What next Establish the foundations for interconnection of the new generation of IMS services beyond frontiers Technical standard for NGN interconnection of services must be timely available for NGN, coordinated with Common IMS, and IMS services that will be standardize by 3GPP, SDOs, OMA and other organizations Next work requires to continue in the coordinated way initiated in Workshop: Technical bodies will continue contribution driven fromtheir participants according with their normal procedures Synchronization through liaisons may have to be reinforce by mixed working groups, follow up sessions or whatever may be decided 26
