Network slice selection, assignment and routing within 5G Networks

Abstract

5G Networks are anticipated to provide a diverse set of services over Network Slices (NS) using Network Function Virtualization (NFV) technologies. We propose solutions to enable NS selection and routing of traffic routing through a NS. A framework for enabling negotiation, selection and assignment of NSs for requesting applications in 5G networks is presented. A definition for service description has been developed, which is then leveraged for negotiation between an application/user equipment and the serving network. Virtualized networks or slices of virtualized networks are selected and assigned based on QCI and security requirements associated with a requested service. We also describe static and dynamic mechanisms for packet routing within NSs.
