Together with partners Ericsson, Nokia and Oracle, the mobile operator is deploying a 5G Standalone core network on a cloud-native architecture.
Network slicing is a fundamental 5G technology that splits up the network into slices. Each of these can be tailored for a specific purpose and act independently, allowing the network to be more flexible.
The network operator adapted the technology to use its 4G network so it can support more end-user devices.
The two companies trialled the technology using a Google Pixel 6 phone.
The 5G Observatory has published its latest report which gives readers an overview of 5G developments within the EU and internationally.
The companies have also agreed to share their findings with the GSMA and the wider industry.
Nokia and Belgian operator Proximus tested the technology at the Proximus 5G Innovation Lab in Brussels.
The German operator also says their 5G services are available in over 200 cities.
The two companies say the trial is the first of its kind to take place in the United Kingdom.
The company says this new network will ensure financial services can continue to operate when mobile voice and messaging services are suspended.
Ericsson describes the trial as a “breakthrough” proof of concept.
