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 Qo. S Committee (PRQC); IPTV Interoperability Forum (IIF); Ordering & Billing Forum (OBF); Telecom Management and Operations Committee (TMOC); and Emergency Services and Interconnection Forum (ESIF) Geneva, 13 -16 July 2009 Fostering worldwide interoperability 2
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, 3 GPP, 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. Geneva, 13 -16 July 2009 Fostering worldwide interoperability 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-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. Geneva, 13 -16 July 2009 Fostering worldwide interoperability 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. To enable the network to support NGN services, advanced application development and end user demands, management of content, settlement, user profiles, security, and Qo. S, 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. Geneva, 13 -16 July 2009 Fostering worldwide interoperability 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. ATIS encourages all relevant standards bodies to work with 3 GPP to extend existing 3 GPP policy architecture to include other access technologies.

Proposed Resolution Add the following text to GSC 13 -CL-17, Resolution GSC-13/10 (GTSC) Next. Generation Networks (NGN) (Revised): to work with 3 GPP to ensure that “Common IMS” supports consistent policy across a range of access technologies, building on the existing 3 GPP Policy and Charging Control (PCC) architecture; and Geneva, 13 -16 July 2009 Fostering worldwide interoperability 8 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 (Id. M) Participants of ATIS’ Packet Technologies and Systems Committee (PTSC) are developing Id. M 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. Geneva, 13 -16 July 2009 Fostering worldwide interoperability 10
ATIS NGN Activities Service Oriented Networks (SON) SON Forum chartered Covered under “New and Novel” Home Networking (HNET) HNET Forum chartered 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. Geneva, 13 -16 July 2009 Fostering worldwide interoperability 11
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 Qo. S/Qo. S 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 Geneva, 13 -16 July 2009 Fostering worldwide interoperability 12
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 Geneva, 13 -16 July 2009 Fostering worldwide interoperability 13
