5G Core Network Slicing for Campus Isolation

The network is segmented into multiple network slices, where each slice represents a logically isolated Campus Network. The 5G Core is divided into separate instances (public 5GC and private 5GC) that can be independently managed while sharing physical infrastructure. This segmentation allows component reuse at the physical level while maintaining logical isolation for security and reliability.

The patent introduces a new dimension of isolation by implementing network slicing in the virtualization layer. Instead of physical separation, isolation is achieved through virtual network functions and logical segmentation. The 5GC instances are separated into public and private domains, with dedicated data repositories and control planes, creating isolation in the virtualization dimension while sharing physical resources.

Multiple Campus Networks are merged into a single shared 5G infrastructure through network slicing. The public 5GC and private 5GC instances are combined on shared physical infrastructure, including common radio access networks and core network functions. This merging reduces the number of separate physical networks needed while maintaining logical isolation through slice-specific configurations and dedicated data repositories.

The shared 5G infrastructure is designed to serve multiple functions simultaneously. The same physical network components (radio access, transmission, core network) can serve both public mobile network operations and multiple private Campus Networks. The 5GC instances are designed to handle both public and private network traffic, providing multi-functionality that reduces operational complexity compared to fully dedicated networks.
