SK Telecom and Nokia claim 5G breakthrough

SK Telecom and Nokia are claiming to have successfully verified the performance of a user plane and control plane separation technique, which they say is a key enabling technology for 5G.

The physical separation of the control plane and the user plane within the LTE core is said to offer the benefits of both centralised and distributed network models, according to the companies.

“Radical renovations on core network architecture is one of the keys to the successful implementation and commercialisation of 5G,” said SK Telecom.

“The core network architecture is restructured into a hybrid network model with distributed user plane functions, controlled by centralised control plane functions for optimal delivery of massive data.”

The companies also unveiled a 5G research and development centre at Nokia Networks’ Korean office. The centre will be used to develop core 5G technologies, including gigabit-level data transmission technology and cloud-based virtualised base stations.

“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 optimise network architecture in preparation for the 5G pilot service demonstration in 2018.”

By the end of 2015 SK Telecom and Nokia Networks aim to open a test bed to verify and demonstrate 5G technologies. Earlier in January 2015 the companies signed a memorandum of understanding for the development of 5G services
