1. State-of-Art CGN
Fixed Network : Status and Problem
▣ Status
 No. 1 in the World in Broadband service deployment (FCC Report, 2002)
 Mature of New Access Network Technology
 Already deployed : ADSL(8Mbps), VDSL(52Mbps) etc.
 Planned and initial stage of deployment : Metro Ethernet, PON etc.
 Extension of WLAN, Broadband Mobile Internet etc.
▣ Problem
 Paradigm shift in Telecommunication Business
 FixedᆞMobile Transition, VoIP, Early saturation of ADSL, Substitution of
Leased line Service with new services (e.g. : IP-VPN, Metro Ethernet, etc.)
 Development of new technology and Preparation for future convergence
 More Bandwidth and Quality : for HDTV class video (20Mbps), etc.
 Laws and regulations for Tele-Broadcasting and others
 Lack of Interworking capa. in heterogeneous network for dynamic services

1. State-of-Art CGN
Mobile Network : Status and Problem
Service Status and Problem
- No. of Subscribers : Almost Saturate (32.4 Million, Feb. 2003)
- New Services : Few services (no more contribution to ARPU)
- Mobile Internet Services :
 Major services : Melody / Graphic down load
 Lack of Interworking with Fixed Network Internet services
Network Status and Problem
- Used Technology : IS-95, cdma2000 1x, EVDO
- Lack of standard model for development of Application
- Difficulty for incorporation of new multimedia services
(Voice based network, Lack of Open Interface)
- Service QoS : Insufficient of QoS in wireless access area

1. State-of-Art CGN
Broadcasting Network : Status and Problem
▣ Status
 Digitalization of CATV based on DMC(Digital Media Center)
 Digitalization of Broadcasting Infra : Terrestrial (End 2001), Sat (2002.3),
CATV(2003.7)
 Provide Bi-Directional Supplementary Services
− Communication type Services : Email, Web-Browsing
− New Services : EPG, PPV, VoD, Walled-Garden, T-Commerce etc.
 Added Business Value with Bundled Services
 Broadcasting + Broadband Internet + VoIP ⇒ Triple Play
 Extention of Business sector with DMB(Digital Multimedia Broadcasting
▣ Problem
 Limitation on Return Channel : Terrestrial / Satellite Broadcasting
 For Bi-Directional services (need interworking with Telecom Network)
 Bandwidth Limitation
