Highlight of Current Activities

• Enhance Service capabilities Voice based to
  Contents based
• Further development of functions for Mobility,
  Multicast, Contents and IdM

3
Highlight of Current Activities

• NGN-GSI (Global Standards Initiative) events
  since the last GSC
• Co-located SG 11 and 13 Meetings
• Mar Del Plata, Argentina, 2 12 September 2009
• Geneva, Switzerland, 19 - 30 April 2010
• Co-located Rapporteur group Meetings Geneva,
  Switzerland, 18-29 January 2010
• Key issues from NGN-JCA (Joint Coordination
  Activity)
• Revised ToR but not serious
• Harmonization among mobility-related Qs
• Support of Future Networks
• Interoperability
• Highlight on Testing Specification
• 7 approved standards and 30 draft texts are
  underway.
• Focus on services / QoS / Monitoring parameters /
  USN and NID / protocol areas

Unlimited Scope by ITU-T Definition (Y.2001)
Next Generation Network (NGN) A packet-based
network able to provide telecommunication
services and able to make use of multiple
broadband, QoS-enabled transport technologies and
in which service-related functions are
independent from underlying transport-related
technologies. It enables unfettered access for
users to networks and to competing service
providers and/or services of their choice. It
supports generalized mobility which will allow
consistent and ubiquitous provision of services
to users.

• No restricted scope if use any types of Packet
• No limited time line whenever use any Packet

5
High Priority Issues in ICT

• Contribution to protect environments e.g.
  Climate Change
• An important and fundamental social
  infrastructure for supporting On-line society
  e-Everything (e.g. healthcare and education)
• A platform for leveraging convergences among
  different industries
• New network technologies and capabilities Bigger
  capacity of Mobile networks, Future Networks, NG
  Optic Technology etc.
• New networking technologies and capabilities
  P2P, DSN, Ad-Hocnetworks, Next Generation Web
  and Cloud computing etc
• New features Smart Grid, Networked Robots, Smart
  Objects, Smart devices, Internet of Things (M2M)
  and others
• Stimulate ICT businesses NGN already 8 years old
  now

What is a future role of NGN?Will NGN cover all
of these requests? Is the market comfortable
enough with NGN?

Strategic Direction

• Remaining enhanced network related capabilities
• Transport control capabilities Mobility,
  Multicasting and QoS control over interworking
• Networking capabilities Ad-Hoc Networks, DSN,
  Multi-connection and Ubiquitous Networking
• Security related Support of IdM and DPI (Deep
  Packet Inspection)
• Service related capabilities
• Service support SIDE (Service Integration and
  Delivery Environments)
• Provider support OSE (Open Service Environment),
  Mobile IPTV and Web based IPTV
• Continue to develop Testing Specification
• From methodology, testing model, architecture to
  detailed service testing such as VOIP service.
• Monitoring parameters set becomes the important
  part for NGN testing and interoperability.

7
Challenges

• Standardization activity would be contributed to
  envisioned of markets and encourage industries?
  what about NGN?
• Puzzled world with many of newcomers such as
  Future Networks, Future Internet, Internet of
  Things, M2M (machine-to-machine), Ubiquitous and
  Web/HTML5 ? how will NGN react to these
  newcomers?
• Common (or consolidated) network visions for the
  future ? Is NGN enough for this?
• Future vision of Telecom-based SDOs like GSC
  members (?)
• Testing Specification
• ITU-T SG11 has specified SIP Call Control
  protocol specifications based on generic UNI and
  NNI Profiles.
• Further detailed service specific descriptions of
  IP Multimedia Call Control Protocol based on SIP
  and SDP may be required but they have not been
  defined yet.

8
Next Steps/Actions

• Continue remaining issues NGN to become more
  stable with enriched capabilities
• More active efforts using NGN capabilities for
  support of convergences ITS (Intelligent
  Transport Systems) and others
• ITU-T SG13 seeks the beyond of NGN
• Future Networks, Ubiquitous Networking, Internet
  of Things
• Others
• The IP Multimedia Call Control Protocol should
  specify the requirements by reference to
  specifications produced by the IETF within the
  scope of SIP and SDP. Parameter value allocations
  to SIP and SDP should be defined within the
  future document.
• New drafts
• Q.NGN interoperability would be a frame work
  Recommendation to specify the general aspect of
  NGN interoperability testing and NGN conformance
  testing
• Q.VoIP conformance testing would specify the
  detailed technical specification for VoIP
  conformance testing based on ITU-T Recommendation
  Q.3402
