o Publish working definitions and terminology document in the context of ICT & CC as an ITU-T recommendation• The terminology definition document is one of the

deliverables of FG-ICT&CC.• It is better to make the terminology document as an ITU-

T Recommendation because it is indispensable for the readers in order to understand the ICT&CC-related Recommendations.

o Definition of ICT (scope in the context of ICT and CC)• e.g. broadcasting business area?, IP-TV? and so on.

Definition of NGN

ITU-T

Rec.

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.


Key Principles of NGN

Open architecture: open to support service creation, service updating, and incorporation of service logic provision by third parties and also support “Distributed control” as well as enhanced security and protection. Independent provisioning: service provision process should be separated from network operation by using distributed, open control mechanism to promote competition. Multiplicity: The NGN functional architecture shall offer the configuration flexibility needed to support multiple access technologies.

General aspects of benefits using NGN on Climate Change

Overall network transformation: NGN is being developed as converged networks that support information, communication and entertainment services for a variety of fixed and wireless access technologies. Such networks eliminate the need for separate purpose-built networks and systems, each of which is an energy consumer and a producer.

Effective resource management and QoS enablement: Traditionally QoS is provided through over-engineering or -provisioning, which means more energy consumption and emission than necessary. ITU-T SG 13 is devising means for QoS assurance in NGN that can reduce the reliance on over-provisioning.

Security and identity management: ITU-T SG13 is developing security and identity management mechanisms that can properly authenticate and authorize the users of NGN services and protect their traffic anywhere, anytime. These mechanisms are fundamental to remote collaboration and virtual office services, which can reduce the need for commuting or traveling.

Key Study Areas of NGN to mitigate Climate Change

Area RationaleRequirements NGN, Mobility management, FMC and IPTV requirements are developed

by the SG13 but no serious attention had been given while we developed.

Requirements are initial process for development of relevant protocols, devices, systems and their operations taking consideration of its maintenance and administrations.

Functions and architecture

NGN, Mobility management, FMC and IPTV functional architectures with related specific functions and functional entities are developed by the SG13 but no serious attention had been given while being developed.

Functional architectures with functional features of each functional entity are fundamental guides for development of relevant protocols, devices, systems and their operations including its maintenance and administrations.

Services & Applications

Various services and relevant capabilities using NGN, Mobility management, FMC and IPTV are developed in SG13 such as RFIDs, USN, Open Service, Web based services, Managed delivery services etc.

Service and operational features should be taken into account impact on climate change whenever they will be revised.


Key Technical Areas of NGN to improve environment

Areas RationaleFMC with Mobility Management capability

Providing FMC (Fixed Mobile Convergence) with Mobility management capability should contribute to reduce number of end user devices which are currently used separately in fixed, mobile and broadcasting environments.

This will also contribute to minimize (or optimize) software packages into terminal device and systems in network/service provider side with using common platform for services.

Improved communications capabilities and services reduces the need for physical travel. Face-to face meetings can be achieved without actually travelling.

USN(Ubiquitous Sensor Network) standards

Further development of using USN technology for active involvement of climate change subject, especially combination of USN with existing industrial technology will open additional opportunity to ICT industry finding various ways of mitigating GHG emission.

It is understood that USN will provide us one of important very active involvements into climate change such as monitoring GHG emission in the field, emergency alerting and appropriate protection for green environments.

NGN Managed service delivery capabilities including QoS and Security

Managed capability in terms of traffic, QoS and Security is one of the important features of NGN ensuring delivery of end user communication requirements. This capability will contribute to develop many of advanced services and applications with reliability which will replace existing various services such as multimedia reliable conference services over FMC reducing (or replacing) physical business trips, etc.

This capability will also contribute to improve network and service operations because this will help for control of activation and de-activation of relevant systems and/or functions inside systems. As a consequence, this will help to reduce energy consumption.


5. Conclusion

ICTs had mainly involved in limited industries such as Telecom,computing etc.

But ICTs are now becoming essential parts of life

Furthermore ICTs is being important parts of social, national andinternational infrastructures

Expansion roles of ICTs

ICTs are rather environment friend than other industrial technologiesbut also have contribution to environment change

ICTs are being widely used whole processes of protecting environment

Several ICTs technologies are used at the field of environment

Roles of ICTs in Protecting Environments

NGN is a common infrastructure for enabling ICTs and other industriesusing ICTs

NGN provides benefits to mitigate GHG by itself including supportvarious capabilities for protection of environments

Position of NGN in Protecting Environments
