[{"name":"S2-2208132","title":"LS from CT WG3: UE Policy Control with PCF re-selection during AMF relocation","source":"CT WG3","contact":"Fuencisla Garcia Azorero","contact-id":43873,"tdoctype":"LS in","for":"Action","abstract":"As already specified in Rel-15 in TS 23.502, 4.16.11, during AMF relocation procedure with PCF reselection, the AMF can create a new UE Policy Association with the new selected PCF. CT WG3 has detected that during this procedure, the UE does not provide to the network the indication of the list of stored PSIs, the ANDSP support or the UE OSId. The behavior of the new selected PCF for this scenario is not fully specified in stage 2. Some CT WG3 companies understand that, at the reception of the UE Policy Association creation request, the new selected PCF interprets that the UE is triggering the 5GS Initial Registration and the UE does not have any UE Policy Section stored for the HPLMN and\/or serving PLMN. In this case, there is the following issue: If the UE stored, due to a previous UE Policy Provisioning procedure, e.g. UE_PolicySection_1, UE_PolicySection_2 and UE_PolicySection_3, and the new selected PCF for the new AMF determines that only e.g. UE_PolicySection_1 and UE_PolicySection_3 apply, the new selected PCF will provide to the UE the UE_PolicySection_1 and the UE_PolicySection_3 (which is unnecessary, because they are already stored in the UE) and the new selected PCF will not be able to remove UE_PolicySection_2 in the UE (which was the only required action in this example). After this procedure, the UE will remain misconfigured until any trigger makes the UE can invoke a 5GS Initial Registration with the indication of the stored PSIs, ANDSP and UE OSId as applicable. Meanwhile, the PCF will not reflect either the actual PSIs stored in the UE. Question 1: At the reception of UE Policy Association creation request, when no indication about the list of stored PSIs, ANDSP support, and UE OSId is received, shall the PCF interpret that the UE is triggering initial registration and the UE does not have UE Policies stored? If not, how does the PCF determine it is a different scenario? Question 2: Additionally, since the new selected PCF does not receive information about the UE's support for ANDSP or UE s support of OSIds, which affect to the proper determination of the ANDSP, how does the ANDSP policies procedure work in this scenario (considering also roaming and V-PCF determination of ANDSP)?. Action: CT WG3 kindly asks SA WG2 to respond to the questions above and to complete and\/or correct stage 2 specifications accordingly.","secretary_remarks":"Responses drafted in S2-2208348, S2-2208859, S2-2209089.
