  6. 2. ITU and Climate Change subject Future Issues from ITU-T FG • 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. • Definition of ICT (scope in the context of ICT and CC) • e.g. broadcasting business area?, IP-TV? and so on.

  7. 2. Key Features of NGN Definition of NGN 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. ITU-T Rec. Y.2001

  8. 2. Key Features of NGN Key Principles of NGN • Open architecture: open to support service creation, service updating, and incorporation of service logicprovision 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.

Key Features of NGN NGN architecture overview (Rec. Y.2012)

  10. 3. Benefits of NGN for Protecting Environment 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.

  20. 5. Conclusion Expansion roles of ICTs • 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 Roles of ICTs in Protecting Environments • 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 Position of NGN 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
