Samsung’s 5G Core solution supports both 4G and 5G networks, offering seamless migration from 4G to 5G. The company’s 5G Core is also designed with critical features to ensure the stability and reliability of the network such as an overload control feature to counteract sudden traffic spikes as well as geo-redundancy support. For geographic redundant deployment, Samsung and KDDI are operating multiple cores in various locations, with each core dimensioned to pick up loads in case one of the active cores becomes unavailable due to traffic bursts or natural disasters.

“We strive to provide the best mobile experiences to our customers through network innovation and our advanced 5G SA network will offer immense capabilities,” said Toshikazu Yokai, Managing Executive Officer, General Manager of Mobile Network Technical Development Division at KDDI. “With Samsung’s 5G SA Core, we will offer unprecedented speed, instantaneous connectivity and high reliability which could bring numerous new experience value for consumers and enterprises. We look forward to continue advancing 5G networks to stay ahead of our customers’ needs.”

“KDDI has been at the forefront of opening up the next frontier of 5G services and we are proud to see our long-term collaboration deepen with new opportunities as we drive continuous innovation and realize technology vision together,” said Junehee Lee, Executive Vice President, Head of Global Sales & Marketing, Networks Business at Samsung Electronics. “We look forward to continuing our collaboration with KDDI to reshape the 5G services landscape in Japan and achieving new 5G milestones.”

The standalone architecture will enable KDDI to create an independent 5G network, enabling lower latency capabilities that are essential to high-performance use cases such as smart factories, automated vehicles, cloud-based online gaming and multi-camera live streaming at sporting events.

Samsung’s 5G Core will also enable KDDI to optimize network slicing — a feature that requires a full 5G SA Core. Network slicing divides a single physical network infrastructure into multiple virtual slices, where each slice is dedicated for a specific user case or application. With this feature, a single network can dynamically support multiple 5G use cases and applications at once, accelerating the delivery of new services and meeting the tailored demands of enterprises and consumers. For instance, operators can create a low latency slice for automated vehicles, an IoT slice for smart factories and a high bandwidth slice for live video streaming — all within the same network.

With the deployment of 5G SA Core, Samsung is providing a wide portfolio of its 5G solutions to KDDI — ranging from RAN to Core. In their collaboration, Samsung has been providing its 5G network solutions which support the operator’s low-, mid- and mmWave spectrum bands — including Massive MIMO radios.

For more than a decade, the two companies have been working together, hitting major 5G networks milestones including KDDI’s selection of Samsung as a 5G network solutions provider and 5G network rollout on 700MHz. Recently, KDDI and Samsung announced the industry’s first demonstration of Service Level Agreements (SLA) assurance network slicing using a RAN Intelligent Controller (RIC) on a live 5G SA network and the initiation of the commercial deployment of Open virtualized RAN (vRAN) sites in Osaka, which is also the world’s first commercial MU-MIMO implementation with O-RAN compliant multivendor interoperability.

Samsung has pioneered the successful delivery of 5G end-to-end solutions including chipsets, radios and core. Through ongoing research and development, Samsung drives the industry to advance 5G networks with its market-leading product portfolio from virtualized RAN and Core to private network solutions and AI-powered automation tools. The company is currently providing network solutions to mobile operators that deliver connectivity to hundreds of millions of users around the world.

The two companies verified the 5G Option 4 technology at the SKT R&D Center to achieve the equal data speed as the NSA, using 175MHz of bandwidth, and also completed the verification of SA’s specialized functions. For this commercial field trial, SKT used Samsung’s 5G SA Core, 5G radios and 4G radios, which are already deployed across SKT’s 5G commercial networks.

5G Option 4 is a more advanced option than the existing 5G Standalone mode (SA Option 2) and provides the equivalent level of speed and quality as the NSA while utilizing the specialized functions of the SA Option 2 such as network slicing and the evolved 5G Core network.

SA Option 4 helps operators deliver innovative services including Urban Air Mobility (UAM), automated vehicles, remote control for heavy equipment, remote control robots and more. Network slicing creates multiple virtual networks within a single physical network infrastructure, optimizing network resources to meet specific performance needs for various services.

“While we supported the launch of the world’s first commercial 5G services in Korea, we are excited to continue spearheading the advancement of 5G through 5G SA technology, which will power innovative 5G services by leveraging the world-class LTE network that is well established in Korea,” said Jong-Kwan Park, Vice President and Head of 5GX Technology Group at SKT. “We will continue to expand our collaboration with industry leaders to continue driving this advanced technology and in growing this 5G SA ecosystem, to demonstrate new ways to tap the full potential of next-generation networks.”

“Through this commercial trial, Samsung is proud to collaborate with SKT to achieve another milestone in advancing 5G SA technology, demonstrating the equal performance as NSA with 5G Option 4 technology in 5G SA mode,” said June Moon, Executive Vice President and Head of Technology Strategy, Networks Business at Samsung Electronics. “We look forward to continue collaborating with SKT for the development and commercialization of advanced 5G SA technology, to deliver market-leading services to consumers and diverse use cases across industry.”

While in the early stages of 5G, operators used E-UTRAN New Radio Dual Connectivity (EN-DC) technology to combine 5G and 4G networks in 5G NSA mode, and now with 5G SA, they can leverage SA Option 4, which is a more advanced dual connectivity technology.

This latest milestone is a result of Samsung and SKT’s continued commitment to developing cutting-edge network technologies that power innovative 5G use cases. As part of their ongoing collaboration, the companies have successfully completed the EN-DC test in 2019, following the world’s first 5G Next-Generation Core (5G NC) trial in June 2018. In March 2021, SKT began delivering 5G SA commercial services to private networks using Samsung’s advanced 5G end-to-end solutions. In a collaborative effort, the companies will continue delivering advanced network services to mobile users in Korea.
