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. The service may also include selecting one of the sets of allowed network slices based on a mobility pattern of the end device. The service may also translate allowed network slices, current tracking area and registration area information, and expose the translated information to an application function.
