Dynamic Authorization for 5G Systems

5G Networks are being designed to provide a diverse set of services using Network Slices (NS) that are enabled by Network Function Virtualization (NFV) and Software Defined Network (SDN) technologies. Given the expected diversity of service offerings and variety of connected devices, it's desirable to have a service authorization architecture that accommodates delivery of services from a variety of infrastructure service providers, while simultaneously protecting these infrastructure service providers from unauthorized service consumption. We illustrate an authorization framework to enable dynamic, context-based authorization for services offered over 5G networks.
