[{"name":"S2-1901414","title":"LS from CT WG4: Clarification request on NF authorization in UE Reachability Notification Request procedure","source":"CT WG4","contact":"Laurent Dubesset","contact-id":47514,"tdoctype":"LS in","for":"Action","abstract":"C4-188044 was submitted at CT WG4#87 but not concluded. It aimed at specifying the stage 3 required changes to TS 29.503 to allow the UDM informing the AMF of the identities of the Network Functions that are authorized to request notifications on this UE's reachability (steps 0a or 0b of UE Reachability Notification Request procedure defined in TS23.502, sub-clause 4.2.5.2). During the discussions, concerns were raised by some delegates whether this procedure is needed at all. Some delegates considered that it is redundant as OAUTH2.0 mechanism defined in TS 33.501 already provides a framework for Authorization of NF service access. In addition, it was commented that the FQDN is not a suitable identity for NF authorization as an HTTP client (in opposition to a Diameter one) doesn't set any origin identity such as a FQDN when sending a request to an HTTP server. The NF Instance Id of the NF Service Consumer is the primary identity for an NF when registering in the NRF and when requesting an OAUTH2.0 token. Action: CT WG4 kindly asks SA WG2 group to: - Clarify the use cases or the service layer consideration for the procedure of UDM providing authorized NF list (steps 0a or 0b of UE Reachability Notification Request procedure defined in TS23.502, sub-clause 4.2.5.2) and AMF using such list for subsequent authorization check, and - Confirm that the authorisation framework defined in TS 33.501 is not sufficient for authorizing NF to request UE's reachability. - If so, confirm that the list of the identities of the authorized Network Functions is a subscriber specific parameter and therefore is part of subscription information that may be stored in the UDR. - If so, remove the FQDN as a possible NF identity in TS 23.502, clause 4.2.5.2.","secretary_remarks":"Postponed S2-1900036 from S2#130.
