Abstract
5G introduces the concept of network slices. Although the 5G standard contemplates some form of slice access control, it is premised on subscriber identity-based checks. Because subscriber identities are associated with/maintained via subscriber identity module (SIM) cards, and because SIM cards can be swapped from one device (user equipment) to another, slice access control based on subscriber identities can fail to prevent unauthorized device access. Systems and methods are provided for enhanced slice access control vis-à-vis an enhanced access and mobility management (AMF), and equipment identity register (EIR) functions. In some embodiments, a localized EIR function can reduce latency/messaging overhead.
