Japanese mobile network operator (MNO) KDDI (au) has tapped South Korean equipment vendor Samsung to provide it with a cloud-native 5G Standalone (SA) Core for its commercial network in Japan. Samsung’s 5G Core, which it notes supports 4G and 5G networks, is also designed with critical features to ensure the stability and reliability of the network such as an overload control feature to counteract sudden traffic spikes as well as geo-redundancy support. The MNO is working with Samsung to deploy multiple cores in various locations to provide geographic redundancy, with each core set up to take on data loads in the event that one of the active cores becomes unavailable due to traffic bursts etc. The SA architecture will enable the Japanese MNO to build out an independent 5G network, enabling lower latency capabilities to support use cases such as cloud-based online gaming.
Commenting on the development, Toshikazu Yokai, managing executive officer, general manager of mobile network technical development division at KDDI, said: ‘With Samsung’s 5G SA Core, we will offer unprecedented speed, instantaneous connectivity and high reliability which could bring numerous new experience value for consumers and enterprises. We look forward to continue advancing 5G networks to stay ahead of our customers’ needs.’
