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
3
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
4
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
5
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.

– Interconnection (NGN, NGCN)
– Network Harmonisation - increase interoperability with other NGNs
and other networks (non IMS).
8
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
9
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.)
10
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
11
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.
12
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.

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
16
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.
17
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)

Still an important part of ETSI working Methods
User STF work
EC Emergency and location work
Security
NGN UCI
19
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.
20
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.
21
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 IPTVContent suppliers-broadcaster etc). This has to be coordinated!
