Two giants complete SLA assurance network slicing test

Samsung Electronics and KDDI announced on Jan. 20 that they had demonstrated Service Level Agreements (SLA) assurance network slicing in a field trial conducted in Tokyo, Japan.

Samsung Electronics is the world’s largest manufacturer of memory chips and smartphones while KDDI is Japan’s top-end telecom operator.

For the first time in the industry, they 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 optimizes the radio resources of the RAN to improve the overall network quality.

Network slicing lets multiple virtual networks be created within a single physical network infrastructure, where each slice is dedicated to a specific application or service — serving different purposes.

For example, 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, according to Samsung.

“Network slicing will help us activate a wide range of services that require high performance and low latency, benefitting both consumers and businesses,” KDDI Managing Executive Officer Toshikazu Yokai said.

“Working with Samsung, we continue to deliver the most innovative technologies to enhance customer experiences.”

Samsung Executive Vice President Lee June-hee said that network slicing would open up countless opportunities by allowing KDDI to offer tailor-made, high-performance connectivity. 

“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.”
