09:00 - 9:30 OPENING SESSION
  • Opening speech: Houlin ZHAO (Director of TSB) [BIO]
  • Welcome address by Susan MILLER (President & CEO, ATIS) [BIO]
9:30 - 11:00 NGN Market Drivers: A Carrier's perspectives

The objective of this session is to obtain the view of several network operators on their vision for NGN, the drivers behind their implementation of NGN, and the most critically important elements for commercial success.

12:30 - 14:00 Lunch Break - Sponsored by AT&T and Nortel
14:00 - 15:30 SESSION 2: An Implementable NGN Architecture and its Capabilities

Achieving an implementable NGN architecture depends upon having technical standards that are sufficiently comprehensive and detailed to allow service providers to leverage existing networks and infrastructure to enhance their ability to offer customers “seamless” delivery of applications independent of any access or transport technology.

To be successful, the NGN target architecture must not only separate services from transport, but must enable efficient interworking between services/applications to support innovative converged services in Fixed Mobile Convergence (FMC) environments. 

This session will discuss the standards-based, implementable NGN architecture taking consideration of: 
  • Overall functional architecture of an implementable NGN architecture
  • Functional architecture for supporting mobility and realization of FMC environments
  • Architectural view points of “Quality of Services” and “Network Performance” to meet NGN service requirements from users and providers
In addition, this session will discuss several key underlying network/support capabilities essential for a successful NGN.

16:00 - 17:30 SESSION 3: NGN Service Enablers 

This session will open with a discussion of service enablers that have been identified as critical to the NGN by the ATIS NGN Focus Group. An overview of the status of the key standards, and the gaps identified, will be provided. This gap analysis is being used to shape future standards work in the ATIS technical committees. 

The concept of mobility is central to the NGN, with mobile subscribers continuing to grow rapidly compared to fixed subscribers. Users and operators place high value on mobility and other innovative new services, and in integrating and simplifying telecommunications and their delivery. The NGN network infrastructure is based on key concepts and architectures from the mobile community with a clear consensus on evolution to a common IP-based access-independent core network infrastructure. It is essential to understand what is required, and what associated standards are required, to effectively address the full range of mobility and associated services, and the opportunities that converged telecommunications provide.

Ethernet is a key technology for the NGN. However, traditional Ethernet networks did not have OAM capabilities appropriate for global, high availability networks. This session will describe the work currently being done in the ITU-T to define OAM standards to support robust, scaleable Ethernet networks.

IPTV is emerging as one of the most interesting near term service opportunities for the NGN. This session will discuss the business drivers behind IPTV, and describe the status of IPTV architecture and standards in ATIS.

10:15 - 11:45 SESSSION 4: Signalling and Control

This session will discuss the necessary core capabilities for signalling and control within the NGN, with a specific focus on IMS as the basis and the areas where critical additional functionality are being specified.In particular, special attention will be given to needed mechanisms for Priority Marking of packets for Emergency Communications and the status of this standards work in ATIS. Additionally, the more general problem of Resource and Admission Control will be discussed as well as the status of this standards work within the ITU-T. 

Session Coordinators/Moderators
ITU-T- Joe Zebarth (Nortel) [BIO] & ATIS – Bob Hall (AT&T) [BIO]
11:45 - 12:45 Lunch Break - Sponsored by AT&T and Nortel
12:45 - 14:15 SESSION 5: Interconnection, Interworking and Evolution

This session will open with a presentation on the User-to-Network Interface supporting the services defined for the NGN. In addition, accomplishment of the goal of Plug and Play devices place requirements in at least three major areas, Auto-Provisioning, Standard SIP Profile & Call flows, and Standardized limited codec selection.

As telecom networks evolve the Network-to Network Interface (NNI) from circuit switched to IP, there is a need for a standard to define the interface to support NGN multi-media services.

Currently there are various implementations and deployments that perform Session/Border Control Functions (S/BCF), [aka, Session Border Control] in service provider, enterprise, access and end-user networks. Defining requirements for these functions and for mapping these to physical implementations is needed to allow for vendor product interoperability and network interconnection.

Interoperability is one of the cornerstones of the NGN. Testing methods and procedures are essential for meeting this goal.

There is a need for end-to-end authentication in a multi-network environment. Whereas these functions can be reliably performed within a single service provider’s network, when networks interconnect, existing protocols and interfaces do not adequately support these needs. The NGN authentication requirements must address the following:

  1. Network Access Authentication (e.g., device authentication, enterprise UNI, end user network)
  2. Service/Application Authentication (e.g., user, device and user/device authentication)
  3. Mutual Network Authentication (e.g., transport level authentication, service/application level authentication across NNI interface)
  4. User peer-to-peer authentication (e.g., authentication of called user or terminating entity, and authentication of originating entity or data origin)
  5. 3rd Party Application/Service Provider Authentication.
  6. Network Authentication by User (e.g., user authenticating the connected NGN network or the service provider) 
  7. Service/Application Specific Authentication (e.g., ETS and TDR specific authentication requirements)
