Forthcoming Turning Point

Expected Broadband Internent

  • Expecting Saturation of Broadband Internet Access Service indicates a New Break-through for Advanced Services

  • Advanced network or Technology for Dramatic Expansion of customer Service Opportunity are desired!

  • NGN has been regarded as for a Vehicle of Customer-based/ Packet-based Service Convergence; Is that on a right way?


Ngn movement worldwide
NGN Movement Worldwide

  • ETSI NGN-SG and NGN-IG

    • ETSI established NGN-starter group last year to investigate NGN feasibility

      • Final report of the work through 2001 identified six working issues in NGN

    • NGN-IG has been operated in 2002

      • Most of Working Issues are based on ETSI TIPHON & MSF architecture

    • Still in a workshop space, actual standardization is not so much activated

  • ITU

    • SG13 created “NGN2004” project in Jan 2002

      • Views NGN as a “realization of GII”

      • Still No reference archive in the home page

    • SG16 leads MEDIACOM2004 project

      • Views NGN as a “IP multimedia convergence”

      • No significant advance after the workshop in April 2001

  • NA/ Others

    • NA: Work has been carried in private sector

    • CTIA’s Approach for WIN –based NGN convergence

      • No significant advance recently

Korean operator’s Launch to NGN

  • Korean Fixed Operators are actually started the deployment of AGW and softswitch as NGN core within a stepwise migration plan

  • Pursuing substitution of timeworn local exchanges, unified management over packet based network functions , and enhancement of service capability

Categories of legacy fmc technology
Categories of Legacy FMC Technology

Commercial Level Convergence

Integrate charging/ billing/ customer interface for Fixed and Mobile customers

ex) Customer Service integration, Unified billing & charging

Service Level Convergence

Interworking Fixed and Mobile service enough to make customer not to feel where he is

ex) one number, UMS, FMC VPN, MNP , FMC portal

Network Level Convergence

Support Fixed and mobile service by means of the same network infra

ex) convergence network
