  2. 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.

  3. 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.

  4. 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.

  5. 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).

  6. 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.

  8. 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.

  9. 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 IP-based Services in the Home Network. As the “fourth network,” the Home Network provides the opportunity to deliver NGN based services to the customer premises.

  10. ATIS NGN Activities • ATIS Committees continue their work to address issues in the NGN space. There are numerous work items currently being address in the following areas: • Unified User Profile • Security • Service Decoupling • Presence • Service Transparency • QoS/QoS Signalling • Resource Management • Resource and Admission Control • Settlement • NGN Management (OAM&P) • Location Based Services • Multicast • Address Resolution (E.164/SIP) • Digital Rights Management • User Control of Profile/Services • Media Resource Functions • Group Management • Emergency Related Services • Wireless/Wireline Convergence

  11. ATIS NGN Activities • Numerous work items underway to specifically address IP-IP interconnect including the following areas: • Services & Adaptation • Next Generation Interconnect Architecture • Connectivity • Association between call control and media control including interactions with the control plane in lower layers • Presence • Access Network Attachment • Policy Decision/Enforcement and Distribution • Session Border Controller (SBC) functions • Network and Traffic Management Functions • Interconnection Service Requirements • Service Specific Requirements – Consideration for SLAs • Form and Agreement Templates • OAM&P
