Samsung Electronics and KDDI have announced the demonstration of service level agreements (SLA) assurance network slicing in a field trial conducted in Tokyo, Japan. The companies proved their capabilities to generate multiple network slices using a RAN Intelligent Controller (RIC) on a live commercial 5G standalone (SA) network. The RIC, provided by Samsung in this field trial, is a software-based component of the Open RAN architecture that optimises the radio resources of the RAN to improve the overall network quality.
Network slicing enables multiple virtual networks to be created within a single physical network infrastructure, where each slice is dedicated for a specific application or service – serving different purposes. 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. This means that a single network can support a broad mix of use cases simultaneously, accelerating the delivery of new services and meeting the tailored demands of various enterprises and consumers.
“Network slicing will help us activate a wide range of services that require high performance and low latency, benefitting both consumers and businesses,” says Toshikazu Yokai, managing executive officer, general manager of mobile network technical development division at KDDI. “Working with Samsung, we continue to deliver the most innovative technologies to enhance customer experiences.”
Through this field trial conducted in Q4 of 2022, KDDI and Samsung proved their capabilities of SLA assurance to generate multiple network slices that meet SLA requirements, guaranteeing specific performance parameters such as low latency and high throughput for each application. Samsung also proved the technical feasibility of multiple user equipment (UE)-based network slices with quality assurance using the RIC, which performs advanced control of RAN as defined by the O-RAN Alliance.
“Network slicing will open up countless opportunities, by allowing KDDI to offer tailor-made, high-performance connectivity, along with new capabilities and services, to its customers,” says Junehee Lee, executive vice president, head of global sales & marketing, networks business at Samsung Electronics. “This demonstration is another meaningful step forward in our efforts to advance technological innovation and enrich network services. We’re excited to have accomplished this together with KDDI and look forward to continued collaboration.”
For more than a decade, the two companies have been working together, hitting major 5G networks milestones that include: KDDI’s selection of Samsung as a 5G network solutions provider, end-to-end 5G network slicing demonstration in the lab, 5G network rollout on 700MHz and the deployment of 5G vRAN on KDDI’s commercial network.
Samsung has pioneered the 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 product portfolio from virtualised 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.
