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, QoSenabled 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

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-Hoc
networks, 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.

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-tomachine), 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.
7
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
