Leading research and development of the infrastructure sharing technique of the public and private networks utilizing open technologies

Toward the latter half of post 5G (after 2025), we anticipate a so-called price collapse of network equipment for private networks, such as Local5G, based on the visions that (1) the infrastructure equipment will become composed of open software (softwarization) and (2) the infrastructure sharing technique of the public and private networks utilizing open interfaces and open software technologies will become prevalent by offering virtual resources of physical equipment to private network operators, through “cloudification” and “softwarization” of MNO (mobile network operators) infrastructure. To that end, we will make the PoC development in three steps, which allows for a large cost cut in deploying private networks in local regions and enables real-world deployment, and confirm the effectiveness of the infrastructure sharing model by university-industry research collaboration, including an MNO, a vendor, a university, and an SIer. Through the research and development of local 5G+5G infrastructure sharing, we will establish new technologies, such as network slicing accommodation for 6G.
