Agenda KI#1: discussing the resolution of the remaining contentious points (ENs) having a quick discussion on the topics of KI#1 that could not be handled (EACI/Relocation) KI#4: discussing the resolution of the remaining contentious points (ENs) KI#7: verifying that the remaining open point can be resolved (EN)
KI#1/1 AF Influence 23.502 4.3.6.2 EN: For HR-SBO case, whether the AF influence procedure in VPLMN should inform HPLMN is FFS. (3702) need to understand why double auth. needed? (Vivo) DNS traffic 23.548 6.7.2.2: PDU Session for supporting HR-SBO in VPLMN "EN:It is FFS how to route the DNS traffic between the UE and the V-EASDF where multiple DNN networks with the same IP address range are deployed in different HPLMNs or in the same HPLMN" (3704) focus on different DNN case "EN: It is FFS if and how DNS with security (i.e, DNSSEC, DoT and DoH) can be supported when using IP replacement (6.7.2.3 step 1b and 4C)." (3704) cannot be supported 23.548 6.7.2.3: EAS discovery procedure with V-EASDF for HR-SBO "EN:It is FFS how to route the DNS traffic between the V-EASDF and HPLMN DNS server when the HPLMN DNS is deployed in a private IP address range." (3704) Input slides from Magnus O/Ericsson & Laurent/Nokia split UL/CL and PSA
KI#1/2 Offloading information 23.548 6.7.2.3: EAS discovery procedure with V-EASDF for HR-SBO "EN:It is FFS how the VPLMN Specific Offloading Information is used by V-SMF in VPLMN" (3704) "EN:How to retrieve QoS parameter from HPLMN to control local PSA is FFS" (3704) try to remove both 23.548 6.7.2.4: EAS discovery procedure with local DNS for HR-SBO "EN:It is FFS how the Local DNS server can detect which FQDN(s) are allowed for HR-SBO offloading. Usage of this configuration may not fit with HR-SBO" (3704) should be resolvable 23.503 6.4: PDU Session related policy information "EN:It is FFS whether to include the Authorized Session-AMBR and charging for local part of DN for VPLMN Specific Offloading Policy." (3705) focus on Authorized Session AMBR Input slides from Magnus O/Ericsson
KI#1/3 EAS rediscovery 23.548 6.7.3 : EAS rediscovery procedure "EN: AF triggered EAS Re-discovery is FFS" (3887) "EN: whether the above EASDF removal applies to intra PLMN mobility is FFS." (3887) "EN: It is FFS whether H-SMF needs to contact UDM to retreive UE subscription during inter-PLMN handover."
KI#1/4 Edge relocation CATT 2751~2753 Input CR from Yuan/CATT EACI Vivo 2264~2265 Huawei 2804~2805
KI#4: Multi-SMF NTT docomo: 3669 Editor's notes in 23.548: 6.2.3.2.7: Coordination among SMFs for common EAS/DNAI determination EN: If and how any of the SMFs can update the common DNAI when UE is moving far away from common DNAI is FFS. EN: how the 5GC determined common EAS/DNAI will be stored in UDR needs further discussion. EN: Multiple SMFs support is FFS. EN: How the UDR locking works is FFS. EN: Whether more than one UE can be considered in common DNAI selection is FFS. (3748) Input slides from Xinpeng/Huawei
KI#7 Remaining topic: whether and how to use UDR is FFS Editors' notes in 23.548 (6.8) EN: Whether and how UDR is used (e.g. How UDR data is to be structured ) is FFS (3251) Editors' notes in 23.502 (5.2.12 UDR services) EN: Related to the DNAI mapping information, it is FFS whether and how UDR is used (e.g. How UDR data is to be structured ) (3888) Input CRs from Magnus H/Ericsson note to be worded to ensure not too big records note on clarifying geographical areas
