KDDI and Samsung claimed an industry first after demonstrating end-to-end network slicing in a standalone (SA) 5G network using a RAN Intelligent Controller (RIC).
The companies stated the trial in Tokyo generated multiple network slices with quality assurance using a RIC, which performs advanced control of the radio network as defined by the O-RAN Alliance. They aim to homogenise end-to-end network slicing with an international standard organisation.
KDDI said there was previously no established technical approach to providing multiple network slices which guarantee service quality end-to-end, noting the demonstration used a new technique to do so by generating slices covering 5G cores and the RIC-equipped radio network.
Toshikazu Yokai, GM of KDDI’s Mobile Network Technical Development Division, said the demonstration “provides a foundation” for “new 5G commercial services” using its network, which went live in late March [1].
Taiyeon Kim, SVP and head of the global technology service team at Samsung’s Networks Business, said the collaboration “is a significant step towards” creating “new business models using 5G technology”.
