Report of ETSI NGN Activities Rainer Münch ETSI TISPAN Chairman Presenter: Ian Spiers Submission Date:June 27, 2008
NGN in ETSI Technical Body – TISPAN Common IMS in 3GPP
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
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
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
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.
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
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).
Home Networks • Analyse the impacts on the “customer environment” derived from the high level system requirements for the support of the TISPAN defined services and capabilities. • Define requirements and specifications to be applied to the customer environment elements (home gateways and customer devices). • Definition of detailed architecture and reference points (within the home network) for the customer network gateway (CNG) and the customer network devices (CNDs) for conversational services. • Definition of detailed architecture and reference points for the customer network devices (CNDs) enabling the IPTV IMS based service usage. • Definition of guidelines for the implementation of security mechanisms in the customer networks
Home Networks – Next Steps • Completion of activities detailing the protocols used by the Customer Gateway and the Customer Network Devices (conversational services) on the basis of the published deliverables on which the reference architectures are defined. • Completion of activities detailing the functions of the customer gateway. • Definition of protocols handled by the Customer device enabling the IPTV IMS based service usage. • Update of the guidelines on security mechanisms for customer networks. • Launch of activities for defining new use cases and requirements for customer networks for TISPAN NGN R3. • Definition of possible new documents detailing specific technical aspects typical for customers networks (e.g. Quality of Service in-home mechanisms, Remote Management issues etc.)
European Home Networking Platform • Efficient broadband deployment & multi-service implementation • Home networking platform is included within ETSI TC ATTM (Access Terminals Transmission Multiplexing) • Home networking platform covers • Telecommunications Access and Home Networks including Terminal Equipment and Network Terminating Equipment. • Copper, fibre and wireless transmission support. • Lower layers of home networks (in collaboration with TISPAN for service implementation). • Collaboration with other relevant bodies within and outside of ETSI (e.g. ITU-T, CENELEC) • Strong telecom position to champion used transmission protocols, e.g. DSL systems in home networking. • Increasing load in customer premises will more than balance any saving actions into the network • PSOs are invited to champion energy efficiency in developed specifications on ICT products, systems and installed ones in order to implement multi-service • PSOs are invited to support usable residential networking guidance towards users (customers) including a greener approach
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.
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.
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)
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.
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
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.
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)
ETSI NGN STF activities • Still an important part of ETSI working Methods • User STF work • EC Emergency and location work • Security • NGN UCI
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.
Other PSOs • Noted that the work on NGN protocols in ITU-T SG 11 is progressing well. • Cooperation between PSOs is continuing. • To be completed during this GSC meeting when information is available.
Challenges • It is noted that caution should be taken to ensure that work is not duplicated in PSOs. In general, cooperation 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!
