▣ 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

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
Mobile Network : Status and Problem

$ Need of New Value Added Services
- Saturation of both Fixed and Mobile telephone services- Need of Integrated (Fixed+Wireless) and Convergence (Telecom+Broad.)
$ Need of New Service Paradigm
- Increase of Service requirements (Flex. of Access, Diversity of Service etc.)- Increase of High Quality services (Beyond QoS over the Internet)
$ Need growing energy for IT Business
- Preparation of New Revenue Stream based on IT Business- Development of new high-tech and market

$ Focus on Convergence- Fixed-Mobile, Telecom-Broadcas., Private-Public etc.- Business Model & Service scenarios (inc. Reg. imp.)
$ Focus on Un-bundle and Bundle- Un-bundle of Services with Transport- Bundling between Services and Applications- Blurring between Control and Management
$ Attention on interworking aspects- NGN could be migrated evolutionary- NGN will provide backward compatibility
