Abstract
Disclosed are embodiments for disabling N1 mode in response to several scenarios including an S-NSSAI failure, searching NR PLMNs after a loss of coverage in an attempt to maintain network slices, and triggering a UE to reattempt authentication of a rejected S-NSSAI when authentication credentials change and the UE either has N1 mode enabled or is camped on LTE PLMN that might be the same as the NR PLMN through which the S-NSSAI was rejected.
