Conclusion

3. Fixed Network : Status and Problem
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

5. Mobile Network : Status and Problem
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

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 : , 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
