SK Telecom and Nokia claim another 5G milestone

Nokia SK Telecom Mou

SK Telecom and Nokia have unveiled one of the first results of their 5G technology collaboration, claiming to verified the performance of a user plane and control plane separation technique, which they reckon is a key enabling technology for 5G.

“The physical separation of control plane and user plane of the LTE core network architecture is an essential technique for building hybrid core network architecture that offers benefits of both centralized and distributed network models,” said the announcement.

It seems that the hybrid network model, with distributed user plane functions controlled by centralized control plane functions, is better for handling large amounts of data. Evolving the LTE core network to better handle exponential increases in data traffic is considered to be a key 5G development.

The collaboration between the two companies has also yielded a 5G R&D centre, which was opened today. “SK Telecom is spearheading the efforts to develop 5G enabling technologies and architecture to flawlessly support high-speed transmission of massive data, including immersive multimedia contents,” said Alex Jin-sung Choi, CTO of SK Telecom. “We will continue to work closely with Nokia Networks to optimize network architecture in preparation for the 5G pilot service demonstration in 2018.”

“A flexible and programmable network architecture is a key part of 5G. Our cooperation with SK Telecom has demonstrated key enablers for it and we look forward to continued cooperation for early 5G introduction,” said Lauri Oksanen, VP Research and Technology, T&I Research at Nokia Networks.”
