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
