2. 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 : Structural Limit for Fixed Network Business
# FixedᆞMobile Transition, VoIP, Early saturation of ADSL, Substitut. 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 High quality HD Video (20Mbps), etc.
# Laws and regulations for Tele-Broadcasting and others
" Lack of Interworking capa. in heterogeneous network for dynamic services

Mobile Network : Status and Problem
Service Status and Problem
- No. of Subscribers : Almost Saturate (32.4 Million, Feb. 2003)
- Services : Few new 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, cdma20001x, 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

Broadcasting Network : Status and Problem
▣ Status
" Digitalization of CATV based on DMC(Digital Media Center)
# Digitalization of Broadcasting Infra : Land (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 : Land / Satellite Broadcasting
# For Bi-Directional services (need interworking with Telecom Network)
" Bandwidth Limitation
