Sony Corporation and KDDI Corporation succeeded at a technological demonstration of concurrent communication on a single device using multiple network slices in 5G standalone network on October 14, 2022.
This demonstration confirmed that smoother gameplay can be achieved by using network slices that have different properties for video signal and control signal, respectively.
This is the world’s first demonstration for using multiple network slices separately for one application. Since January 2021, Sony and KDDI have been evaluating technologies to create new entertainment services and business use cases based on 5G SA, which include this demonstration.
The demo confirmed that a game application can concurrently use multiple network slices with different properties for image data and control data. The option to select network slices is delivered from the 5G core network to an Xperia smartphone.
In the future, customized network slices will allow for reliable communication with low latency, and video signals will be optimized according to the wireless environment, enabling even more stable game play even when the wireless environment changes.
Back in February 2022, Sony and KDDI also succeeded at a technical demonstration for a game streaming service to use network slicing with 5G SA which proved that users can play their PlayStation (R) 5 or PlayStation (R) 4 games on a smartphone while away from home.
