KT Builds Korea's First '5G Integrated Core Network'... A Step Closer to SA Commercialization

[Asia Economy Reporter Koo Chae-eun] KT has developed and completed the deployment of core network technology that can simultaneously support 5G Standalone (SA) and Non-Standalone (NSA) modes for the first time in Korea.

According to KT on the 3rd, KT began commercial 5G service based on NSA in April last year and was the only domestic telecom operator to introduce CUPS technology into the NSA core network, laying the foundation to integrate SA support. Since then, KT has continuously advanced this technology and succeeded in developing its own ‘5G Integrated Core Technology’ that can simultaneously support NSA and SA standards for the first time in Korea.

KT closely collaborated with Samsung Electronics from the design stage to build the ‘5G SA-NSA Integrated Core Network.’ In particular, KT plans to apply the 5G integrated core technology to eight edge communication centers nationwide. Through this, KT aims to quickly provide 5G ultra-low latency services to SA users via a nationwide 5G integrated core network based on edge communication centers.

Seo Young-su, Head of KT Network Research and Technology Division (Senior Executive Director), said, “At the time of 5G commercialization, KT proactively introduced CUPS with consideration for not only NSA but also SA services, enabling the first successful construction of a 5G integrated core network in Korea. KT will continue to pursue ‘network innovation’ to support customers’ comfortable communication experience and the digital transformation of companies amid COVID-19.”
