SK Telecom's 5G Roaming Technology Adopted as Research Project by Global Mobile Operators' Council
Published2017.03.08 18:08Research projects selected by NGMN are proposed as 3GPP standards after discussion.
SK Telecom announced that the core 5G roaming technology it proposed has been finally approved as a 2017 research project by the Next Generation Mobile Networks (NGMN).
Research projects selected by NGMN are proposed as 3GPP standards after undergoing research, development, and discussions with global mobile operators.
At the NGMN board meeting held in Barcelona on the 26th of last month, SK Telecom proposed 'cross-border 5G infrastructure interoperability technology' as a new research project for NGMN in 2017, together with global mobile operators including Deutsche Telekom, British Telecom, Singtel, and Bell Mobility (Canadian mobile operator).
NGMN selected four new research projects for 2017: technology for inter-country 5G infrastructure interoperability, 5G security technology, efficiency improvement through 5G network modularization, and data transmission efficiency improvement through separation of wireless transmission network functions. Among these, 'technology for inter-country 5G infrastructure interoperability' is a project proposed by SK Telecom.
'Inter-country 5G infrastructure interoperability technology' is a roaming technology that enables users to receive network services of the same quality as in their home country even when using 5G in other countries.
On February 14, SK Telecom, together with Deutsche Telekom and Ericsson, developed "inter-operator network slice interoperability technology," which is a core component of "cross-border 5G infrastructure interoperability technology." Accordingly, NGMN is also expected to research 'inter-country 5G infrastructure interoperability technology' centered on this technology.
5G TTI is a program launched by NGMN in June of last year for the early commercialization of 5G. It consists of divisions for defining core 5G technologies, verifying technologies in a laboratory environment, interoperability between equipment, and verifying technologies in the pre-commercialization stage, and researches technologies according to the stages of technological evolution for commercialization.
SK Telecom is leading the early standardization of 5G by standardizing the interoperability between terminals and base stations, between base stations and core networks, and between 4G equipment and 5G equipment, which is essential for 5G standardization and commercialization, in the interoperability division.

SK Telecom First Applies AI-Based Network Operations at Gwanghwamun K-Pop Concert
SK Telecom announced that it applied an AI-based network operation system for the first time at a large-scale K-pop concert held in the Gwanghwamun area of Seoul on March 21st, managing communication quality throughout the event. Mobile data usage during the three hours before and after the concert reached 12.15TB, approximately doubling compared to the same time slot the previous weekend. SK Telecom monitored traffic using the AI system 'A-One' in five-minute and 50-meter units to respond to potential overload situations, while also operating temporary communication facilities and on-site personnel in parallel. This case is interpreted as confirmation of the practical applicability of AI-based autonomous network operation in an environment where demand from dense events and foreign users increases simultaneously.
