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.
Claims20
A method comprising:
- receiving an indication of rejection to all of one or more of requested slices over 3GPP access;
- disabling N1 mode capability over 3GPP access based on the indication;
- and
- enabling the N1 mode capability over 3GPP access based on a slicing subscription change indication when performing Public Land Mobile Network (PLMN) selection.
A User equipment (UE) apparatus comprising:
- a processor;
- and
- a memory storing instructions that, when executed by the processor, configure the apparatus to:
- receive an indication of rejection to all of one or more of requested slices over 3GPP access;
- disable N1 mode capability over 3GPP access based on the indication;
- and
- enable the N1 mode capability over 3GPP access based on a slicing subscription change indication.
A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a computer, cause the computer to:
- receive an indication of rejection to all of one or more of requested slices over 3GPP access;
- disable N1 mode capability over 3GPP access based on the indication;
- and
- enable the N1 mode capability over 3GPP access based on a slicing subscription change indication.
