SK Telecom announced on February 15 that it developed federated network slicing, one of the most important techniques for the realization of 5G communication networks, for the first time in the world in cooperation with Deutsche Telekom and Ericsson and succeeded in demonstrating the technology.

During the demonstration of the technology on February 14 (local time), Deutsche Telekom’s research institute located in Germany and SK Telecom’s 5G infrastructure in Incheon City, South Korea were connected to each other by means of network slicing. Then, engineers around the world could repair aircraft components based on the remote control of augmented reality (AR) robots and without any speed delay.

Network slicing can be defined as software-based realization of a network exchanger, an authentication server and the like for network function virtualization (NFV) and connection of them to a mobile carrier located abroad. In the case of international roaming based on network slicing, 5G services such as those provided in connected cars and AR and virtual reality (VR) services are available as usual in an optimized network.

It differs from the previous generation of international roaming in that it is free from a speed delay because it does not have to pass through a domestic server. On the part of developers working on 5G services, it can contribute to development cost reduction and development time reduction as they do not have to adapt themselves to different network environments of different countries and mobile carriers.

SK Telecom is planning to turn the technology into an international standard by proposing it as a 5G standard of the 3rd Generation Partnership Project (3GPP).
