The core will exist in a cloud-based environment, enabling network slicing that can offer customized connectivity – and all slices can run on the same, shared infrastructure. This will provide a much more flexible solution than a single physical network, providing a maximum level of connectivity. The packet core network handles wireless access authentication and authorization, as well as network point of presence. Moving to 5G there will exist different migration paths, either based on Evolved Packet Core (EPC) or based on a newly defined core network architecture, 5G Core.
