Samsung and SK Telecom advance in bringing Korea closer to 5G standalone commercialization

Samsung Electronics and SK Telecom (NYSE: SKM) today announced the successful completion of Korea’s first interoperability assessment between 5G Standalone (SA) Core and other commercial network systems over a 5G network. This successful result brings the two companies one step closer to 5G SA commercialization.

The 5G SA Core, jointly developed by Samsung Electronics and SK Telecom, not only supports technologies including network slicing and function modularization based on 3GPP standards, but also offers additional functions that operators have been using since LTE, include billing, subscriber management and operational convenience system. The interoperability assessment is the final stage for verifying the validity of 5G SA data transmission, signifying that the SA system is ready to be launched for commercial service.

Both companies implemented several cutting-edge technologies in the 5G SA Core that has been used for the interoperability. The technologies include Data Parallel Processing technology that performs QoS and transmission control simultaneously; Data Acceleration technology that classifies and distributes similar traffic types; and Path Optimization technology that automatically delivers data traffic to Mobile Edge Computing (MEC) platform.

Once 5G SA is commercialized, data processing efficient will be improved by threefold, allowing efficient control for supporting massive data traffic.

For the past five years, the two companies have been collaborating on LTE and 5G development, which ultimately led to this successful 5G SA Core interoperability test. Some of other accomplishments include the commercialization of Virtualized LTE Core and Packet Optimization system; and they have completed the development of 3GPP Rel. 15 based SA Core in July last year, and successfully launched 5G NSA commercial service in April this year.
