Research on 5GC Cloud-Native Deployment Mechanism Based on Cloud-Edge Collaboration

With the proliferation of 5G business scenarios, 5G core network (5GC) cloudification has a major trend for both operators and vendors. As a novel cloud computing technology, cloud native can realize agile development, rapid deployment, on-demand customization of resources, and flexible business innovation of 5GC. In order to promote the cloud native evolution of 5GC, this paper proposes a prototype of cloud native 5GC platform based on open source projects, and conducts deployment experiment. However, open source projects have shortcomings in the deployment of cloud native 5GC, such as being unable to remote user plane function (UPF) to edge cloud, not supporting multiple network planes, and relying on static network function IP addresses. From the conclusion of experiment, a set of cloud-edge collaboration 5GC deployment solutions are accomplished, proving cloud native technology can carry the services of 5GC.
