    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

    # FixedMobile 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
