Abstract
The CJK Meeting on Information and Telecommunication Standards aims to promote the mutual
exchange of views and information about the status of the information and telecommunication industries
in China, Japan, and Korea and to contribute to the work of standards organizations at the regional andglobal levels. This article outlines the activities of the CJK Standards Meeting and the formation of therelated standards development organizations in Korea and China.

1. Outline
The CJK (China-Japan-Korea) Meeting on Information and Telecommunication Standards (CJKStandards Meeting) started in June 2002 on the initiative of ARIB (Association of Radio Industries andBusinesses) and TTC (The Telecommunication Technology Committee) of Japan, CCSA (China Communication Standards Association) of China, and TTA(Telecommunications Technology Association) ofKorea. These four standards development organizations (SDOs) recognized that mutual understanding
and cooperation were necessary to promote the soundgrowth and development of the information andtelecommunication industries. To encourage mutualunderstanding and cooperation in fields of commoninterest, the four SDOs signed a memorandum ofunderstanding (MoU) covering the following sixobjectives.
(1) To mutually exchange views and informationon the status of information and telecommunication industries in the three countries(2) In coping with new challenges in standardization, to contribute to the work of standards
organizations at the regional and global levels(3) To encourage mutual support and assistanceamong the four SDOs to ensure balanced andmutually beneficial development of standards† NTT Access Network Service Systems LaboratoriesChiba-shi, 261-0023 Japan

in the three countries(4) To sustain the commitment and contribution to
the regional and global standards bodies, while
making efforts to address the needs of the markets and industries of the three countries(5) To periodically hold a meeting based on theagreement entered into by the four SDOs toachieve the four objectives above(6) To provide non-periodic opportunities for consultations and discussions about key concerns
in standardization activities such as informationexchange meetings at the technical committeelevelThe three countries have held five meetings to date:the 1st CJK meeting in June 2002 in Korea, the 2ndin November 2002 in Japan, the 3rd in November
2003 in China, the 4th in July 2004 in Korea, and the
5th in March 2005 in Japan.
2. Structure
Originally the CJK Standards Meeting consisted ofjust plenary meetings for high-level informationexchange. The Beyond 3G Working Group (B3GWG) was set up to cover topics related to the nextgeneration mobile communication topics at the 3rdmeeting and the NGN (Next Generation Network)
WG was established at the 4th meeting. The CJKStandards Meeting now consists of both plenary
meetings and these two WGs for experts. Each WG
has its own discussions and reports its progress in theplenary meetings. The structure of the CJK Standards

Testing Laboratory, which provides one-stop services
from the establishment of IT (information technology) standards to the testing and certification for IT
standards products. Figure 3 shows the organizational structure of TTA, which re-organized its TechnicalCommittees (TCs) on a project basis to enable it toadjust to the rapid progress of technology. Now, 45Project Groups (PGs) make up four TCs on common
infrastructure, telecommunication, radio communications, and IT applications. The Technical Assembly(TA) establishes TTA standards by approving drafts
proposed by PGs. The Coordination Committee (CC)
has the authority to create and dissolve PGs.

3. NGN WG
The NGN WG was established in July 2004. One ofthe authors (Y.M.) was appointed as its chair. ThisWG discusses standardization concerns of commoninterest related to service requirements, quality class,quality of service (QoS) control, and interoperability
between the NGN and other networks. Since NGN isalso a key issue in ITU-T, views have been exchanged
not only in this WG but also in the ITU-T NGN focus
group and SG13 plenary meeting to achieve further
cooperation and progress.
4. Formation of SDOs in Koreaand China
4.1 TTA (Korea)
As shown in Fig. 2, two ministries in Korea are concerned withstandardization activities: the Ministry of Information and Communication (MIC) and the Ministry ofCommerce, Industry and Energy(MOCIE). MIC controls the information and telecommunication
technology fields and has a relationship with ITU. MOCIE controls
the Industrial Standards Commission and works with ISO and IEC(International ElectrotechnicalCommission).
TTA was established as a nongovernmental SDO in 1988. As amember of several international
standards organizations, it has been
contributing to global cooperation
as well as setting information communication standards in Korea. It
recommends TTA-standards toMIC as domestic standards. In
December 2001, it opened the IT

December 2002 with the approval of the Chinese
Ministry of Information Industry (MII), Standardization Administration of China, and the Civil Affairs
Ministry in order to support the rapidly growing
telecommunication industry, promote corporate participation in standardization activities, and encourage
