1. Frameworks of Telecom Building a Society l Basic & Fundamental need of all human being l Need at least two people l Need tools for communication (5 senses: See, Hearing, Touch, Smell, Taste) See Hearing Touch Smell Taste

1. Frameworks of Telecom Objective of Telecommunication - 1 l Minimum condition for building real society See Hearing Standard for Telecom Quality of Services 1. 5 m

1. Frameworks of Telecom Objective of Telecommunication - 2 l Objective of Communication: Building virtual society using communication services/systems similar as real society 1. 5 m

1. Frameworks of Telecom Basic Configuration of Telecommunication l Wires l Transmission l Switching Systems Transmission Systems Wires (User side) l Terminal Systems Switching Systems Wires (Transmission) Terminal Systems

2. Trends of Telecom The vision of ubiquitous networking Services on the Convergences • Always on with Any devices • Anytime, anywhere and in any form • Voice and multimedia • Self service, intuitive • Simple for the end user • Secure, trusted and reliable

2. Trends of Telecom Key Features of NGN Next Generation Network (NGN): ITU-T Rec. Y. 2001 a packet-based network able to provide telecommunication services and able to make use of multiple broadband, Qo. S-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.

2. Trends of Telecom Overall NGN Architecture • NGN= Service Stratum + Transport Stratum • Basic Functions= User + Control + Management

2. Trends of Telecom Enabling for Convergence Business/Application oriented projects Limited Services BE IP Limited BB FMC N G N • Simple linkage btw layers • Simple business relationships • Simple players RFID IPTV Others Managed IP Converged Broadband • Simple linkage btw layers with dynamics • Diverse and Flexible business relationships • Diverse business models and players

3. Protect Environment Focal points on ICT & CC: support to protect environment Protect Natural Environment • Green House Gas emission • Pollutions of natural environment: Air, Water etc. • Natural disaster: earth quake, fire, thnami etc • Other natural disaster Impacts Protect Cultural Environment Historical monuments Artistic items: Paints, Sculptures etc. Musical items: Musical instruments etc. Literary items: Books, Records etc. Infrastructural items: Building of Museum, Theater for Performance etc. • Other cultural environments • • •

3. Protect Environment Way of using Energy is one of the major key concerns • ICTs itself are subject for control of Energy (generation and consumption) • ICTs will impact on using Energy (Delivery & consumption control) • Network infrastructure in the core of ICTs Healthcare Ind. Vehicle Ind. Merchand izing Ind. Education Ind. Travel Ind. others Move Off line to On -line Life (inc. Business) Using Energy ICTs Network Infras.

3. Protect Environment Energy considerations aspects of Network l Planning aspects: for example “Over-provisioning” vs. “Plannedprovisioning” and others l Operation aspects: for example “Always on” vs. “Stand by” and “Best effort” vs. “Managed” and others l Service aspects: Single media vs. Multimedia, Single service vs. Binding services or Convergence between different service environments l System aspects: Data storages, OAM&P systems, Router, Switch, Transmission systems, Duct operation, Emergency Power Feeding and others l Office operation aspects: Number of Offices and people within offices, Office operation related systems (e. g. lights, ventilation, cooling, Heating and others) l Others § Requirements (Operation, Planning and Functions) § Capabilities for services and OAM&P (including Qo. S, Security and Mobility etc. ) § Functions and features allocation into functions impact § Protocols (for example to support “Stand by” mode) § System design and specification including power feeding conditions § others

3. Protect Environment Example from BT: NGN impact overall network operation N G N 30 ~ 40% Reduction of Sites • • • Resulting by More Broad bandwidth Extend Reachability Support Convergence Service vs. Transport Integrated Management Others

3. Protect Environment Example of candidate trials: ECO Networking Technology l ECO Routing § Aggregate traffic into energy-saving path § Implement sleep mode for routers where possible l ECO Switching § Forward packets on timeslot basis with time scheduling § Buffer-less forwarding without packet loss § No routing table necessary * ECO: Energy Cost saving Overlay * Ref: FGFN-C 25 “Energy Saving Network Technologies”, Fujitsu Ltd, 11. 2009
