Method and system for application exposure and network slice selection based on registration area
A method, a device, and a non-transitory storage medium are described in which a registration area-based application exposure and network slice selection service is provided. The service may include the generation of multiple sets of allowed network slices based on a type of end device, current tracking area, and registration area information.
