NGN – Current Activities (1)
 ATIS’ work on the NGN crosses every facet of the
organization.
 ATIS committee leaders and experts (*PTSC, PRQC, IIF,
OBF, TMOC, NGIIF, and ESIF) are collaborating to
coordinate work items with inter-committee dependencies
on a wide variety of topics, such as NGN architecture, NG
carrier (IP) interconnect, policy management, service
oriented networks, convergence, 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 Forum (OBF); Telecom Management
and Operations Committee (TMOC); Next Generation Interconnection Interoperability Forum (NGIIF); and
Emergency Services and Interconnection Forum (ESIF)

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.
 Current activities include defining Data Border Function
(DBF) requirements to enable web, data, and content
services to be provided by the NGN.
 Develop converged policy management requirements in
order to provide seamless services independent of
access.
 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)
 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, service oriented network.
5
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
6
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

No changes proposed to existing Resolution
(GSC-14/10) at this time.

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 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
 Service Oriented Networks (SON)
• SON Forum addressing work to enable the interoperability and
implementation of SON applications and services, including
identifying key service enablers applicable to multiple carrier
networks, and simultaneously standardizing the relevant APIs.
