Nokia of Finland, working with Japanese fixed and mobile operator KDDI (au), has completed a 5G core standalone (SA) network trial, moving the operator closer to being able to provide 5G-enabled services. In a press release, the vendor noted that the standalone trial used Nokia’s 5G AirGile cloud-native core solution and was conducted ‘entirely independently of previous generations’ mobile network architecture’. Nokia claims its 5G AirGile cloud-native core can be rolled out in a traditional network environment or a cloud environment and is fully compliant with 3GPP Release 15 5G core functions. The trial reportedly applied ‘a service-based architecture to the 5G control plane, moving control functions completely into a cloud-based environment which provides operators with improved scalability, velocity and flexibility’. As the Japanese operator progresses plans to evolve from a non-standalone (NSA) 5G core network to a full 5G SA core, the trial should help ensure that both parties understand the key requirements, roadmap and performance of a 5G core SA deployment.
Commenting, John Harrington, Head of Nokia Japan, said: ‘For Nokia, 5G is much more than radio. It’s an end-to-end network transformation. We are pleased to have successfully completed this 5G core SA network trial together with KDDI, as it marks a crucial milestone for KDDI’s 5G SA deployment as well as for Japan’s 5G.’
