In an official newsroom post, Samsung announced that it, along with KDDI, has successfully completed the demonstration of Service Level Agreements (SLA) assurance network slicing on a live 5G SA (Standalone) network in Tokyo, Japan. This is the first time in the industry that companies have generated multiple slices of the network using the RAN Intelligent Controller (RIN) on a live 5G SA network.
Apparently, the RIN provided by Samsung is a software version of the Open RAN architecture that optimizes the radio resources of the RAN to improve the overall network quality. FYI, network slicing allows multiple virtual networks to be created within a single physical network infrastructure, where each slice serves a different purpose.
For example, one slice can transmit a low latency slice for automated vehicles or a high bandwidth slice for live video streaming. Toshikazu Yokai, Managing Executive Officer and General Manager of the Mobile Network Technical Development Division at KDDI, said, “Working with Samsung, we continue to deliver the most innovative technologies to enhance customer experiences.”
The successful demonstration of SLA network slicing on a live 5G SA network guarantees Samsung and KDDI will offer tailor-made high-performance capabilities and services such as low latency and high throughput. This collaboration also marks Samsung's long-standing equipment relationship with KDDI. This includes 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.
