Disabling a pending nssai

A User Equipment (“UE”) apparatus comprising:

• a processor;
• and
• a memory coupled to the processor, the memory comprising instructions executable by the processor to cause the UE apparatus to:
• receive, from a lower layer, a first indication of a radio link failure event, wherein the radio link failure event occurs during an authentication of a network slice, and wherein the radio link failure event corresponds to unavailable cell coverage;
• disable a pending network slice selection assistance information (“NSSAI”) associated with the network slice based at least in part on the radio link failure event;
• receive, from the lower layer and after disabling the pending NSSAI, a second indication indicating available cell coverage;
• and
• transmit a registration request for the network slice in response to the available cell coverage, wherein the registration request comprises a requested NSSAI, and wherein the requested NSSAI comprises one or more single network slice selection assistance information (“S-NSSAI”) associated with the pending NSSAI.

A method of a User Equipment (“UE”), the method comprising:

• receiving, from a lower layer, a first indication of a radio link failure event, wherein the radio link failure event occurs during an authentication procedure of a network slice, and wherein the radio link failure event corresponds to unavailable cell coverage;
• disabling a pending network slice selection assistance information (“NSSAI”) associated with network slice based at least in part on the radio link failure event;
• and
• receiving, from the lower layer and after disabling the pending NSSAI, a second indication indicating available cell coverage;
• and
• transmitting a registration request for the network slice in response to the available cell coverage, wherein the registration request comprises a requested NSSAI, and wherein the request NSSAI comprises a single network slice selection assistance information (“S-NSSAI”) associated with the pending NSSAI.

An access and mobility management function (“AMY”) apparatus comprising:

• a processor;
• and
• a memory coupled to the processor, the memory comprising instructions executable by the processor to cause the AMF apparatus to:
• receive, from a Radio Access Network (“RAN”) node, an indication of a radio link failure event associated with a User Equipment (“UE”), wherein the radio link failure event occurs during an authentication procedure of a network slice;
• disable a pending network slice selection assistance information (“NSSAI”) associated with the network slice based at least in part on the radio link failure event;
• and
• receive, from the UE and after disabling the pending NSSAI, a registration request for the network slice, where the registration request comprises a requested NSSAI, and wherein the request NSSAI comprises a single network slice selection assistance information (“S-NSSAI”) associated with the pending NSSAI.
