5.7 NSSAI delete test function

38.5093GPP5GSRelease 17Special conformance testing functions for User Equipment (UE)TS

5.7.1 General

The SS use the NSSAI delete test procedure to delete different type of NSSAI information in the UE, see Figure 5.7.1-1. The different types of NSSAI information that can be deleted in a NSSAI DELETE REQUEST message are Default configured NSSAI, Configured NSSAI or Allowed NSSAI information, see clause 6.7. The NSSAI delete test procedure is limited to delete one type of NSSAI information. To delete more than one type of NSSAI information the SS needs to repeat the procedure for each type of NSSAI information.

5.7.2 Initiation

The SS requests the UE to delete NSSAI information by transmitting a NSSAI DELETE REQUEST message and the UE confirms the deletion of the requested NSSAI information by responding with a NSSAI DELETE RESPONSE message.

5.7.3 Reception of NSSAI DELETE REQUEST message by UE

When UE receives NSSAI DELETE REQUEST message then the UE shall:

1> if the UE is operating in RRC_CONNECTED state:

2> if Delete NSSAI type = 00:

3> Delete the default configured NSSAI stored at the UE if any.

2> else if Delete NSSAI type = 01:

3> if Octets 3,4 and 5 all set to "00000000":

4> Delete configured NSSAI for all PLMNs stored at the UE if any.

3> else if at least one of octets 3,4 or 5 <> "00000000":

4> Delete configured NSSAI for the PLMN indicated by octet 3,4 and 5 stored at the UE if any.

2> else if Delete NSSAI type = 10:

3> if Octets 3,4 and 5 all set to "00000000":

4> if Access type =00:

5> Delete allowed NSSAI associated with 3GPP access for all PLMNs stored at the UE if any.

4> else if Access type =01:

5> Delete allowed NSSAI associated with non-3GPP access for all PLMNs stored at the UE if any.

4> else if Access type =10:

5> Delete allowed NSSAI associated with both 3GPP and non-3GPP access for all PLMNs stored at the UE if any.

4> else

5> The UE behaviour is unspecified.

3> else if At least one of octets 3,4 or 5 <> "00000000":

4> if Access type =00:

5> Delete allowed NSSAI associated with 3GPP access for the PLMN indicated by octet 3,4 and 5 stored at the UE if any.

4> else if Access type =01:

5> Delete allowed NSSAI associated with non-3GPP access for the PLMN indicated by octet 3,4 and 5 stored at the UE if any.

4> else if Access type =10:

5> Delete allowed NSSAI associated with both 3GPP and non-3GPP access for the PLMN indicated by octet 3,4 and 5 stored at the UE if any.

4> else

5> The UE behaviour is unspecified.

2> else

3> The UE behaviour is unspecified.

2> Transmit NSSAI DELETE RESPONSE message.

1> else:

2> the UE behaviour is unspecified.
