1. Objective of Telecommunication
Building a Society
 인간 행위의 기본 욕구 중 하나 (인간 = 사회적 동물)
 최소 두 사람 이상이 필요
 대화 수단이 필요 (오감 이용 : 시각, 청각, 촉각, 후각, 미각)

2. Trends of Telecommunication
Historical trend on Telecom development
근대 통신
초기 통신
– 인간  인간 (직접 접촉, 제3자를
이용한 서한 전달)
– 우편 제도의 발달(운송 수단의 발전)
– 전기적 전달 수단 (유선 : 전신 등)
– 자연 전달 수단 (봉화, 깃발 등)
현대 통신
근 미래 통신
– 광 및 브로드밴드 무선 전달기술 중심
– 유, 무선을 모두 이용 (전화, 방송 등)
– 정보이용의 제한성 극복 (개인이동성,
– 통신망/Always-On 접속을 형성
– 다양한 유형의 정보이용 (음성, 문자,
단말 이동성)
– 다양한 정보이용 : 멀티미디어 기반의
실감형 정보 및 Connect things 활성화
그래픽, 영상 등)
– 광통신 및 브로드밴드 (유/무선) 일반화

4. Convergences and NGN
Overall trend of near Future
Future should direct to the Convergence
• Vision: Any Time, Any Where, Any Services and
Any Devices
• FMC should be the 1st instantiation
• 2nd should be the IPTV
• Any information/services over any transport
infrastructures: VoDSL, TVoMobile, etc.
Convergence classifies into following:
• Internal Convergences (within a industry): FMC,
IPTV and others
• External Convergences: between/among different
industries, e.g., Telematics/ITS, USN, e-Health,
Networked Robotics and others
부산동의대 4 March 2009
4. Convergences and NGN
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

4. Convergences and NGN
Convergences in various aspects
Network Convergence: Internet, NGN etc.
Service Convergence: FMC, IPTV etc.
Terminal Convergence: PC, PDA, Int .Phones etc.
Business Convergence: Triple, Quadruple Play etc.
Connecting to Anything

4. Convergences and NGN
Definition 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, 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.

NGN in 4 words…
• by Fixed
• by Mobile
• by Wireless
NGN = Broadband Managed IP Network
• for Services
• for Businesses
• for Players
• for Users

4. Convergences and NGN
NGN; a Convergence Platform
 Combination IP with Broadband accelerating intrinsic convergence
• Service convergence: Web based service provisioning
• Network convergence: IP over any broadband transport networks
 Advanced Mobile and Wireless technology initiate business
convergence such as Fixed-Mobile convergence
 Broadband Fixed, Wireless and Mobile technology boost another
business convergence, called “Multiple Play: Tele-Broadcasting”

IPTV is defined as multimedia services such as
television/video/ audio/text/graphics/data
delivered over IP based networks managed to
provide the required level of QoS/QoE, security,
interactivity and reliability
