Network slice for visited network

Abstract

Systems, apparatuses, and methods are described for wireless communications. Network slicing may be used to provide services for a wireless device. A network slice may be used for a wireless device based on an application function that may be located in a home public land mobile network (PLMN) or in a visited PLMN.
