Fixed Network Status and Problem
1. State-of-Art CGN

• 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
• Fixed?Mobile 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

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

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
