NGN – Current Activities (1)
ATIS’ work on the NGN crosses every facet of the
organization.
The ATIS NGN Focus Group’s Framework (2004), Roadmap
(2005), and Gap Analysis (2006) framed the industry’s
discussion and now, implementation of standards activities in
support of NGN is on an aggressive timeline.
ATIS committees (*PTSC, PRQC, IIF, OBF, TMOC, and ESIF)
are creating or coordinating solutions to pressing issues on
NGN architecture, security, network management, OSS/BSS,
quality of service, and emergency services.
ATIS is also expanding its NGN work with initiatives on
(Service/Network) Convergence, Identity Management, Home
Networking, Service Oriented Networks, Next-Generation
Carrier (IP) Interconnect and Policy Management.
*ATIS’ Packet Technologies and Systems Committee (PTSC); Network Performance,
Reliability, and QoS Committee (PRQC); IPTV Interoperability Forum (IIF); Ordering &
Billing Forum (OBF); Telecom Management and Operations Committee (TMOC); and
Emergency Services and Interconnection Forum (ESIF)

NGN – Current Activities (2)
ATIS’ focus is on functions/elements of the NGN
to enable innovated converged services.
Over 77 technical/operational issues underway in
ATIS’ committees directly related to the NGN;
with countless others indirectly related.
Current activities include the development of
mechanisms to ensure delivery of complex
services across and between the IMS, SOA, and
Web 2.0 domains (i.e., NG-Service Enablers), to
include service quality management; and to
provide consistent Policy Management.
ATIS is coordinating its NGN work with numerous
standards development organizations including,
ITU-T, 3GPP, IETF, ETSI TISPAN, TMF and
Broadband Forum to name a few.

NGN – Current Activities (3)
Enhancing border element functions to include
Data Border Function, and defining functional
requirements for:
Web Services Gateway
External Application Gateway
Decomposing Session Border Control functions
and interfaces to explicitly include a policy
decision function in the signaling path.

Strategic Direction
Effectively promote the development of the NGN in
a logical, actionable and implementable manner.
Create a standardization process for NGN that
capitalizes on the “bottom-up” contribution process
to address real-world operational issues and “topdown” process to define strategic direction.
Foster closer collaboration among groups developing
NGN related standards.
Coordination among ATIS committees and external
standards organizations already takes place on a regular
basis.
Continue to advance specifications/ standards for
enabling the next generation converged, service
oriented 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.
To enable the network to support NGN services, advanced
application development and end user demands, management
of content, settlement, user profiles, security, and QoS, across
multiple domains and networks are required.
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
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
Add the following text to
GSC13-CL-17, Resolution
GSC-13/10 (GTSC) NextGeneration Networks (NGN)
(Revised):
to work with 3GPP to ensure that “Common
IMS” supports consistent policy across a
range of access technologies, building on the
existing 3GPP Policy and Charging Control
(PCC) architecture; and

ATIS NGN Activities
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 chartered to develop 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.
