[{"name":"S2-2506126","title":"LS from CT WG3: Questions on TEI19_SliceSel","source":"CT WG3","contact":"Xiaojian Yan","contact-id":72885,"tdoctype":"LS in","for":"Action","abstract":"AF can request network slice replacement via Nnef_AMPolicyAuthorization API or Nnef_AMInfluence API. Currently, the Nnef_AMPolicyAuthorization API supports the AF requests targeting an individual UE, while the Nnef_AMInfluence API supports the AF requests targeting one or multiple UEs. However, Clause 5.15.5.2.2a of TS 23.501 only specifies the AF requested network slice replacement for a UE. Question 1: Can the AF provision the same AF requested Network Slice Replacement requirements for the same Replaced S-NSSAI for more than one UE simultaneously? Clause 5.15.5.2.2a of TS 23.501 also states that if the replacement is successful, the AMF removes the Replaced S-NSSAI from the Allowed NSSAI. Question 2: Can the Replaced S-NSSAI be part of only the Allowed NSSAI or can it also be part of the Partially Allowed NSSAI for the UE?. Action: CT WG3 kindly asks SA WG2 to answer the questions and update the specification accordingly if needed.","secretary_remarks":"Responses drafted in S2-2506224, S2-2506490, S2-2506673, S2-2506782.
