▣ 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

Fixed 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

Mobile 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

$ 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

Study Scope of Next Generation5. Conclusion
