ATIS: Advancing the Next Generation Network Wayne Zeuch, ATIS
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, WTSC, 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, cloud services, 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); Wireless Technologies and Systems Committee (WTSC); 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. • Develop converged policy management requirements in order to provide seamless services independent of access. • Addressing NG9-1-1 and IP network interface to Emergency Services Networks. • ATIS is coordinating its NGN work with numerous standards development organizations including, ITU-T, 3GPP, NENA, IETF, ETSI 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 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. • 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 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 • ATIS supports the reaffirmation of the existing NGN Resolution contained in: • GSC-15/10: Next Generation Networks (NGN) 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 (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 • Cloud Services • CSF focusing on the operators' provision of cloud services and development of a framework to ensure integration of the network and IT. It will account for basic APIs in the control plane layer of the network rather than as a service on the network, define a minimum set of APIs to expose between service providers, and define interoperability, security, and standardization, among other things, between service provider clouds. • Emergency Services • Developing standards to help migrate from the wireless PSTN- to an IP- and IMS-based emergency services network.
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/QoSSignalling • 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
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
