NGN – Current Activities
• 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, and Next-Generation
Carrier (IP) Interconnect.

NGN – Current Activities
• ATIS’ focus is on NG-network interconnection and
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; service creation environments;
service development; service delivery; service orchestration;
common data modeling; and BSS/OSS.
• ATIS is coordinating its NGN work with numerous standards
development organizations including, ITU-T, 3GPP, IETF, ETSI
TISPAN, TMF and DSL Forum to name a few.

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-time
operational issues and “top-down” 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
• Realization of 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).
5
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 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 (NGCI)
– Participants from ATIS technical committees addressing standards
issues to ensure TDM-to-IP and IP-to-IP interconnection to deliver rich
content and features to the end-user over a range of access network
types while considering QoS, security, and policy management.

ATIS NGN Activities
• Service Oriented Networks (SON)
– To develop and deliver complex services expediently across and
combining the aspects of the domains of IMS, SOA, and Web2.0,
the standardization of fundamental interfaces and the methods
exposure of enabling elements to developers across a wide range
of expertise must be investigated.
• Home Networking (HNET)
– Investigating the issues associated with the deployment of IPbased Services in the Home Network. As the “fourth network,” the
Home Network provides the opportunity to deliver NGN based
services to the customer premises.
