Section: 5.2.13.2.2 Nbsf_Management_Register service operation
Content: Service Operation name: Nbsf_Management_Register Description: Registers the tuple (UE address(es), SUPI, GPSI, MBS session ID, DNN, S-NSSAI, PCF address(es), PCF instance id, PCF Set ID, level of Binding) for a PDU Session or for a UE. NOTE 1: In some cases only subset of these parameters may be registered (e.g. UE address(es) will be registered only if PCF registration is for a PDU Session and for MBS sessions SUPI and GPSI are also not available). Inputs, Required: [Required, if PCF registration is for a PDU Session], UE address(es), PCF address(es), DNN [Required, if PCF registration is for a PDU Session], S-NSSAI [Required, if PCF registration is for a PDU Session], MBS session ID as defined in TS 23.247[ Architectural enhancements for 5G multicast-broadcast services ]  [78] [Required, if PCF registration is for a MBS Session]. UE address can contain IP address/prefix or MAC address as defined in TS 23.501[ System architecture for the 5G System (5GS) ]  [2]. It can optionally include Framed Route information. W-5GAN specific UE IP address information is specified in TS 23.316[ Wireless and wireline convergence access support for the 5G System  (5GS) ]  [53]. Framed Route information is defined in Table 5.2.3.3.1-1. NOTE 2: For support of time sensitive communication and time synchronization (as described in clause 5.28.3.2 of TS 23.501[ System architecture for the 5G System (5GS) ]  [2]) the UE address contains the DS-TT port MAC address for Ethernet type PDU Session. Inputs, Conditional: SUPI [Required, if PCF registration is for a UE or required by the local policy in PCF if the registration is for a PDU session, otherwise it is optional]. NOTE 3: The PCF can be configured to always provide a SUPI to the BSF, e.g. to support UE ID retrieval from the BSF. Inputs, Optional: GPSI, PCF instance ID and PCF Set ID, level of Binding (see clause 6.3.1.0 of TS 23.501[ System architecture for the 5G System (5GS) ]  [2]). NOTE 4: DNN and S-NSSAI are not applicable when the PCF registration is for a UE. NOTE 5: It is up to stage3 to ensure an unambiguous error proof way for the BSF to differentiate between PCF for a PDU Session and PCF for a UE. This may or may not require providing the BSF additional parameter(s) when a PCF registers itself with the BSF. Outputs, Required: Result indication, Binding Identifier for a PDU Session, or for a UE, or for an MBS session. Outputs, Optional: None.
