Initial REGISTRATION with Default configured NSSAI indication bit set to "Requested NSSAI created from default configured NSSAI" in Network slicing indication IE

[laurent-dubesset]

Hello,

I'd like to test the case below defined in TS 24.501 clause 5.5.1.2.2 Initial registration initiation

If the UE has neither allowed NSSAI for the current PLMN nor configured NSSAI for the current PLMN and has a
default configured NSSAI, the UE shall:
a) include the S-NSSAI(s) in the Requested NSSAI IE of the REGISTRATION REQUEST message using the
default configured NSSAI; and
b) include the Network slicing indication IE with the Default configured NSSAI indication bit set to "Requested
NSSAI created from default configured NSSAI" in the REGISTRATION REQUEST message.

We have removed Configured NSSAI values, set Default configured Default NSSAI with sNSSAI value [sst: 0x01;sd: 0x000001] and performed an initial registration with UERANSIM.
As expected the Requested NSSAI in the NAS REGISTRATION REQUEST message contains the Default configured NSSAI but the Network slicing indication IE is missing in the message.
Before this test we have run some others with the same IMSI so I wonder if there is any Allowed NSSAI stored for that IMSI somewhere that prevents UERANSIM logic to send the Network Slicing indication.
If so can you tell me how to delete the stored Allowed NSSAI?

Thanks
