2NGN in ETSI
- Technical Body TISPAN
- Common IMS in 3GPP
3TISPAN 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/Op
en - TISPAN NGN specifications can be considered as
THE global NGN solution
4TISPAN is today

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).
9Home 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
10Home 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.)
11European 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
12Numbering, 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.
13NGN 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.
14TISPAN NGN R2 security

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
17Network 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.
18Testing 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)
19ETSI NGN STF activities
- Still an important part of ETSI working Methods
- User STF work
- EC Emergency and location work
- Security
- NGN UCI
20Next 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. - TISPANs 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.
21Other 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.
22Challenges
- 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!
