Section: 5.4.4b UE 5GSM Core Network Capability handling
Content: The UE 5GSM Core Network Capability is included in PDU Session Establishment/Modification Request. The UE shall indicate in the UE 5GSM Core Network Capability whether the UE supports: - "Ethernet" PDU Session Type supported in EPC as PDN Type "Ethernet"; - Reflective QoS; - Multi-homed IPv6 PDU Session (only if the Requested PDU Type was set to "IPv6" or "IPv4v6"); - ATSSS capability (as referred to clause 5.32.2); - Transfer of Port Management Information containers; - Support for secondary DN authentication and authorization over EPC (as referred to clause 5.17.2.5). The 5GSM Core Network Capability is transferred, if needed, from V-SMF to H-SMF during PDU Session Establishment/Modification procedure. After the first inter-system change from EPS to 5GS for a PDU session established in EPS, the 5GSM Core Network Capability is also included in the PDU Session Modification if the Reflective QoS and/or Multi-homed IPv6 PDU Session is present.
