'For the PDU session whose S-NSSAI is replaced without PDU session re-establishment, the SMF continues the reporting for the replaced S-NSSAI and the SMF uses the Usage Report including the Alternative S-NSSAI received from the UPF for the report to the EIF for the replaced S-NSSAI.' CT WG3 has the following question about the above requirement: Question 1: Should the SMF also include the Alternative S-NSSAI in the Energy Consumption information reporting to the EIF when the initial S-NSSAI is replaced by an Alternative S-NSSAI?. Action: CT WG3 kindly asks SA WG2 to address the above questions and update their specifications accordingly.","secretary_remarks":"Responses drafted in S2-2600326, S2-2600668, S2-2600772, S2-2600844, S2-2600976, S2-2601066.
