security, IdM, network management, OSS/BSS, quality
of service, and emergency services.
* ATIS’ Packet Technologies and Systems Committee (PTSC); Network Performance,
Reliability, and QoS Committee (PRQC); IPTV Interoperability Forum (IIF); Ordering & Billing

NGN – Current Activities (2)
• ATIS’ focus is on defining requirements on interfaces
and functional elements of the NGN to enable innovated
converged services.
• Numerous technical/operational work items underway in
ATIS’ committees directly related to the NGN.
• Develop converged policy management requirements in
order to provide seamless services independent of
access.
• Addressing NG9-1-1 and IP network interface to
Emergency Services Networks.
• ATIS is coordinating its NGN work with numerous
standards development organizations including, ITU-T,

NGN – Current Activities (3)
• Defining a suite of NG carrier interconnect standards in
order to provide end-to-end multimedia services.
• Decomposing Session Border Control functions and
interfaces to explicitly include a policy decision function
in the signaling path.
• Defining a suite of standards in support of priority
communications addressing service requirements,
network element requirements, security and
authentication requirements, and end-to-end call flows in
support of Emergency Telecommunications Services
(ETS).

Strategic Direction
• Effectively promote the development of the NGN in a
logical, actionable and implementable manner.
• ATIS coordination/program management across
committees to provide interoperable end-to-end solutions
addressing cross-technical and cross-operational issues.
• Foster closer collaboration between ATIS and external
standards organizations developing NGN related
standards.
• Continue to advance specifications/standards for
enabling the next generation converged network.

Challenges
• Convergence and NG-service delivery to the end user will
require the interaction of non-traditional telco aspects such as
web services, data models, and applications.
• Enabling the network to support NGN services, advanced
application platforms, management of content, settlement,
user profiles, security, and QoS, across multiple network and
operational domains.
• Logical orchestration of common service functions between
network architectures and resources, whether physical or
virtualized, must be developed.
• Definition of common industry best practices and policies is
needed to define/determine the accessibility/availability of
service enablers and data to outside application/service
developers (i.e., what, when and how).
• Service convergence requires that policy be applied across all
access technologies.

Next Steps/Actions
GSC16-GRSC9-09
• ATIS will continue to advance convergence through the
development of standards across technology and/or service
domains to meet consumer demands for converged
services/applications – anytime, anywhere, by any means.
• Faster development of new and converged services is
dependent upon underlying service enablers and applications.
ATIS will continue its efforts to advance the service creation
environment in the NGN.
• ATIS will continue to develop standards needed to ensure that
rich content and features can be delivered to the end-user.
• ATIS realizes the success of NGN depends upon global
interoperability of NGN services and therefore will continue its
outreach and interaction with other global standards
organizations.
• ATIS encourages all relevant standards bodies to work with
3GPP to extend existing 3GPP policy architecture to
include other access technologies.

Proposed Resolution
•
GSC16-GRSC9-09
ATIS supports the reaffirmation of the existing
NGN Resolution contained in:
–
GSC-15/10: Next Generation Networks (NGN)
GSC-15-CL-15
2 September 2010
RESOLUTION GSC-15/10: (GTSC) Next Generation Networks (NGN) (Revised)
The 15th Global Standards Collaboration meeting (Beijing, 30 August – 2 September 2010)
Recognizing:
a) that there is an agreed definition for the NGN concept developed by the ITU;1
b) that the NGN concept covers a range of applications including Public Switched Telephone
Network/Integrated Services Digital Network (PSTN/ISDN) emulation, multimedia, video
streaming and other services, based on standardized service building blocks;
c) that all GSC Participating Standards Organizations (PSOs) are actively involved in the
developing of NGN standards;
d) that 3GPP and 3GPP2 have agreed to adopt a common “IP Multimedia Subsystem” (IMS)based approach to implementing an NGN, that this approach is now being used in
broadband fixed networks, including cable networks;
e) that the scope of 3GPP has recently been expanded to encompass a “Common IMS” to
address the needs of the ICT community beyond GSM/UTRAN, including wireline, cable,
and fixed-wireless networks;
f) that a call server approach has been included in the architecture for NGN;
g) that technologies supporting services such as messaging, Voice over IP (VoIP) and
multimedia are now being deployed and are in service in a number of areas;
h) that users of NGNs and interconnected networks will demand adequate Quality of Service
and security;
i) that there are different stages of network evolution and therefore interconnection to/and
between NGN environments is becoming an important issue to the deployment of NGN
and the migration from legacy networks to NGN; and
j) that the industry requires technical integrity and coherence among interrelated
specifications.
k) that the evolution of the NGN is driven by innovations in user applications and network
capabilities;
l) that interoperability continues to be important to NGN.
Considering:
a) that NGN must interwork with and allow a migration path from existing networks and
services;
b) technical standards for NGN interconnection must become available in a timely and coordinated manner to allow global operation of NGN services including converged services;
c) that offering end-to-end multimedia services, including mobility support and IPTV,
requires interconnection across different NGN implementations capable of supporting
satisfactory security and end-to-end Quality of Service (QoS) and Quality of Experience
(QoE);

ATIS NGN Activities
GSC16-GRSC9-09
• Service/Network Convergence
– To support equipment interworking for the evolution of NGNs,
standards were investigated to specify core service
requirements, definitions, use cases and a bootstrap of the NGN
architecture.
• Identity Management (IdM)
– Participants of ATIS’ Packet Technologies and Systems
Committee (PTSC) are developing IdM deliverables and
coordinating and aligning their work with ITU-T Study Groups.
• Next Generation Carrier Interconnect (NG-CI)
– PTSC NG-CI Task Force developing IP network to network
interconnection guideline based on ATIS Standards that will
provide physical configuration, protocol suite profile, operational
information to be exchanged between carriers, and test suites in
order to support conformance and interoperability testing.

ATIS NGN Activities
GSC16-GRSC9-09
• Cloud Services
– CSF focusing on the operators' provision of cloud services and
development of a framework to ensure integration of the network
and IT. It will account for basic APIs in the control plane layer of
the network rather than as a service on the network, define a
minimum set of APIs to expose between service providers, and
define interoperability, security, and standardization, among
other things, between service provider clouds.
• Emergency Services
– Developing standards to help migrate from the wireless PSTNto an IP- and IMS-based emergency services network.
