SK Telecom, the largest mobile operator in Korea and Samsung Electronics have successfully completed 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 commercialisation.
The 5G SA Core, jointly developed by SK Telecom and Samsung Electronics, not only supports technologies including network slicing and function modularisation 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.
“Along with the initial phase of NSA rollout, SK Telecom has been continuously focusing on researching and developing the SA technology in order to provide customers a differentiated service quality with innovative products, which will be launched in the first half of next year,” said Park Jin-hyo, Chief Technology Officer and Head of ICT R&D Center at SK Telecom. “By strengthening bilateral collaboration with Samsung, SK Telecom will drive and lead highly innovative 5G technologies and solutions.”
“The fundamental structure of 5G SA is built on a completely new configuration, successfully delivering the most optimised 5G service to customers and enterprises across numerous industries,” said Jaeho Jeon, Executive Vice President and Head of R&D, Networks Business at Samsung Electronics. “Maintaining Korea’s leadership in network innovations through continuous investments in next-generation technologies is important to Samsung and SK Telecom, and the companies will continue to collaborate on developing and commercialising 5G SA.”
Once 5G SA is commercialised, data processing efficient will be improved by threefold, allowing efficient control for supporting massive data traffic. Moreover, 5G SA system is highly optimised for emerging next generation services such as Autonomous driving, Smart Factory, Smart Farm, and AR/VR.
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 commercialisation 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.
