RRA’s Five International Standard Proposals for 5G, Cloud Computing, and Quantum Cryptography Communication Technology Were Adopted by ITU


The National Radio Research Agency (RRA) under the Ministry of Science and ICT (MSIT, Minister Lee Jong-ho) announced, "At the ITU-T Future Networks Study Group (SG13*) held in Geneva, Switzerland from July 4 to 15, five international standard proposals for 5G, cloud computing, and quantum cryptography (Head of the Korean Delegation: Dr. Kim Hyung-soo from KT) developed by Korea were consented**. Korea also secured 11 leadership positions for the SG13."
* SG13: Study group on setting and revising standards related to future networks
** The stage just before the final adoption of a standard; if there is no disagreement through circulation among member countries, the standard is adopted.

[Five International Standard Proposals Consented]

① The “Requirements and framework for jitter guarantee in large scale networks including IMT-2020 and beyond” standard prevents data delay in large scale networks, providing stable and secure services. Based on this, the standard is expected to contribute to the promotion of industries related to ultra-low latency services in 5G, Internet, and the metaverse.
* Jitter: The amount of change in latency of data transmitted and received

② The “Cloud computing – Functional requirements of cloud service partner for multi-cloud” standard, which is the first Korean-led development of multi-cloud technology standard, provides the concept and functional requirements of multi-cloud. ③ The “Cloud computing – Global Management Framework of Distributed Cloud” standard defines the requirements of distributed cloud, a core 5G application technology. The two standards are expected to create a broader new market for the existing cloud computing environment and serve as a guide.
** Multi-Cloud: An environment that uses cloud services from two or more cloud providers simultaneously
*** Distributed Cloud: Cloud on a network close to service users, not on a central server

④ The “Quantum key distribution networks (QKDN) - Functional architecture for quality of service assurance” and ⑤ “Quantum key distribution networks – Requirements for machine learning based quality of service assurance” standards are about technologies for guaranteeing the quality of quantum cryptography communication networks that are drawing attention as one of the security communication technologies for the future. It is expected that they will greatly contribute to the establishment of quantum cryptography communication networks that use these technologies and the commercialization through service quality assessment.

As a new study period (2022-2024) began after the World Telecommunications Standardization Assembly (WTSA) held in March, the reorganization of the leadership positions of the Future Network Study Group (three Working Parties, 13 Questions under Study) was discussed.

Korea secured 11 leadership positions for the SG13—9 seats re-elected and two seats additionally elected, including the working parties in the cloud and big data sectors and the JCA-ML* whose establishment was led by Korea.
* JCA-ML : Group that jointly coordinates standardization activities between study groups and cooperates with other standardization organizations such as ISO/IEC to prevent duplication of machine learning standards development within ITU-T

The RRA said, "We will continue to work with industry, academia and research institutions to lead international standardization activities in future network fields such as quantum, space, 6G, artificial intelligence and cloud."
