摘要
It is recognized herein that current methods and systems for performing procedures in 5G systems may not adequately protect the confidentiality and/or integrity of exchanged NSSAI and other identifiers. In methods and systems that protect NSSAI by not initially sending unprotected NSSAI, a non-optimal AMF may be selected for use by a UE, and an AMF relocation procedure may need to be performed when the NSSAI is later sent in a protected manner, wasting time and resources. In methods and systems with persistent UE identifiers, it may be possible to map the identifiers to users of an AMF and track those users. Various embodiments described herein address solutions to these and other issues.
