Section: 5.2.8.2.5 Nsmf_PDUSession_CreateSMContext service operation
Content: Service operation name: Nsmf_PDUSession_CreateSMContext. Description: It creates an AMF-SMF association to support a PDU Session. Input, Required: SUPI or PEI, DNN, AMF ID (AMF Instance ID), RAT Type, Serving Network (PLMN ID, or PLMN ID and NID, see clause 5.18 of TS 23.501[ System architecture for the 5G System (5GS) ]  [2]). Input, Optional: PEI, S-NSSAI(s), Alternative S-NSSAI, PDU Session Id, N1 SM container, UE location information, UE Time Zone, AN type, H-SMF identifier/address, list of alternative H-SMF(s) if available, old PDU Session ID (if the AMF also received an old PDU Session ID from the UE as specified in clause 4.3.5.2), Subscription For PDU Session Status Notification, Subscription for DDN Failure Notification, NEF Correlation ID, indication that the SUPI has not been authenticated, PCF ID, PCF Group ID, Same PCF Selection Indication, DNN Selection Mode, UE PDN Connection Context, GPSI, UE presence in LADN service area, indication that "the PDU Session is subject to LADN per LADN DNN and S-NSSAI", GUAMI, backup AMF(s) (if NF Type is AMF), Trace Requirements, Control Plane CIoT 5GS Optimisation indication, Small Data Rate Control Status, APN Rate Control Status. Backup AMF(s) sent only once by the AMF to the SMF in its first interaction with the SMF, UE's Routing Indicator optionally with Home Network Public Key identifier or UDM Group ID for the UE, EPS Interworking indication, EPS Bearer Status. Target ID (for EPS to 5GS handover), "Invoke NEF" flag, target DNAI, additional following for SM context transfer: SMF transfer indication, Old SMF ID, SM context ID in old SMF (see clause 4.26.5.3), HO Preparation Indication, indication of no NG-RAN change. MA PDU request indication, MA PDU Network-Upgrade Allowed indication, Indication on whether the UE is registered in both accesses, Satellite backhaul category, GEO Satellite ID, PVS FQDN(s) and/or PVS IP address(es) and Onboarding Indication in the case of ON-SNPN, Disaster Roaming service indication, HR-SBO allowed indication, Indication of UE supports non-3GPP access path switching. Output, Required: Result Indication and if successful SM Context ID. Output, Optional: Cause, PDU Session ID, N2 SM information, N1 SM container, S-NSSAI(s). When the PDU Session is for Emergency services for a UE without USIM, the AMF provides the PEI and not the SUPI as identifier of the UE. When the PDU Session is for Emergency services of an unauthenticated UE with an USIM, the AMF shall provide both the SUPI and the PEI and shall provide an indication that the SUPI has not been authenticated. See clause 4.3.2.2.1 clause 4.3.2.2.2 clause 4.11.1.2.2 and clause 4.11.1.3.3 for details on the usage of this service operation. See clauses 4.22.2.1 and 4.22.3 for detailed usage of this service operation for ATSSS. See clause 6.7 of TS 23.548[ 5G System Enhancements for Edge Computing; Stage 2 ]  [74] for HR-SBO allowed indication.
