Network Virtualization Enables Same Quality Service Provision Abroad as Domestically

SK Telecom has developed technology that enables 5G communication services to be utilized across national boundaries.

SK Telecom, together with Deutsche Telekom and Ericsson, has developed 'inter-operator network slicing interworking' technology, which is a core element of 5G network infrastructure, and successfully demonstrated it at the Deutsche Telekom 5G Research Institute located in Bonn, Germany.

'Network slicing interworking' technology is a 5G technology that interconnects virtualized networks by service with overseas telecommunications carriers, enabling third-party customers to receive the same quality of network service when using 5G services such as AR or VR in different countries as they would domestically.



Conventionally, when constructing networks to be utilized for services such as connected vehicles and IoT, separate network equipment had to be deployed for each service, which not only required significant costs but also made efficient network operation difficult. Accordingly, in the 5G era where data transmission volume and service types are increasing explosively, network virtualization is emerging as a core technology.

Bruno Jacobfeuerborn, CTO of Deutsche Telekom, stated, "Customers want to receive consistent quality service regardless of their physical location," and added, "This technology development will serve as a starting point for customers to receive high-quality service from anywhere."
