NGN in TISPAN
Common IMS in 3GPP
Source: Rainer Muench, TISPAN Chairman
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
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.
6
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
7
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).
8
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.

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
13
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.
14
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)
15
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.
16
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 IPTVContent suppliers-broadcaster etc). This has to be coordinated!

2) NGN Interconnection of Services
NGN Interconnection of Services
ETSI Board Strategic Topic
Source:
Fernando Soriano
Claudio Gentile
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
19
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
20
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.

GAP Analysis: Requirements
GSMA IPX
Requirements
3GPP Rel-8
3GPP Rel-9

GAP Analysis: Architectures
GSMA
3GPP
TISPAN
Direct or Indirect Interconnection
(Service/Transport Level)
Direct Connection (Rel8) (between
CS, IMS cores, not ISP/ASPs)
Rel 9 (SA1 starting TR) will cover
also indirect interconnection
scenarios.
Service
Interconnection
SoIX
architecture
and
use
case
scenarios defined for both direct
and indirect interconnection. Note
that IMS Direct Interconnection
was tasked to 3GPP (“II-NNI”)
Proposal of a TISPAN IPX.
E2E QoS is a must in IPX. Use
of Internet discouraged.
E2E QoS relies simply on
overprovisioning and marking of User
Plane IP packets (using DiffServ).
Both Internet and e2e QoS based
models (inter-RACS signaling is
under definition)
TISPAN IPX includes carrier grade
service interconnection
Mainly targeted to GPRS or IWLAN roaming and interworking
of data services.
Direct Interconnection for both IP
services or legacy PSTN/PLMN
multimedia serv.
Interconnection for IP services or
legacy PSTN/PLMN.
Numerous requirements over
IPX Proxy.
No technical definition for IPX proxy
No technical definition for IPX
proxy.
Some requirements over
operator Border Nodes
(screening, firewall, GRE
tunnels)
Border Nodes: IBCF + TrGW not fully
defined.
No Ix interface defined. No
firewall/QoS control. No GRE
support.
Border Nodes: IBCF + RACS +
IBGF highly defined.
Gq’ interface: QoS/NAT/Firewall
control.
No support for GRE tunnels.
Interconnection Interfaces (NNI):
Radius, MMS, IMS…
IMS-NNI (Ici/Izi) under specification
SIP-I NNI only starting.
NNI Definition ongoing (TR only):
either IMS, SIP-I or BICC/IP

NGN Interconnection Workshop
9 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
24
NGN Interconnection Workshop
9 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
25
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 from their
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
