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)

4

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.”

High Priority Issues in ICT

5

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

6

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-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.

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 8
