NFProfile
NF profile in 23.501
NF profile of NF instance maintained in an NRF includes the following information:
- NF instance ID.
- NF type.
- PLMN ID.
- Network Slice related Identifier(s) e.g. S-NSSAI, NSI ID.
- FQDN or IP address of NF.
- NF capacity information.
- NF priority information.
NOTE 1: This parameter is used for AMF selection, if applicable, as specified in clause 6.3.5. See clause 6.1.6.2.2 of TS 29.510 [58] for its detailed use.
- NF Set ID.
- NF Service Set ID of the NF service instance.
- NF Specific Service authorization information.
- if applicable, Names of supported services.
- Endpoint Address(es) of instance(s) of each supported service.
- Identification of stored data/information.
NOTE 2: This is only applicable for a UDR profile. See applicable input parameters for Nnrf_NFManagement_NFRegister service operation in clause 5.2.7.2.2 of TS 23.502 [3]. This information applicability to other NF profiles is implementation specific.
- Other service parameter, e.g. DNN or DNN list, notification endpoint for each type of notification that the NF service is interested in receiving.
- Location information for the NF instance.
NOTE 3: This information is operator specific. Examples of such information can be geographical location, data centre.
- TAI(s).
- NF load information.
- Routing Indicator, for UDM and AUSF.
- One or more GUAMI(s), in the case of AMF.
- SMF area identity(ies) in the case of UPF.
- UDM Group ID, range(s) of SUPIs, range(s) of GPSIs, range(s) of internal group identifiers, range(s) of external group identifiers for UDM.
- UDR Group ID, range(s) of SUPIs, range(s) of GPSIs, range(s) of external group identifiers for UDR.
- AUSF Group ID, range(s) of SUPIs for AUSF.
- PCF Group ID, range(s) of SUPIs for PCF.
- HSS Group ID, set(s) of IMPIs, set(s) of IMPU, set(s) of IMSIs, set(s) of PSIs, set(s) of MSISDN for HSS.
- Supported Analytics ID(s), NWDAF Serving Area information (i.e. list of TAIs for which the NWDAF can provide analytics) if available in the case of NWDAF.
NOTE 4: The NWDAF's Serving Area information is common to all its supported Analytics IDs.
- Event ID(s) supported by AFs, in the case of NEF.
- Application Identifier(s) supported by AFs, in the case of NEF.
- Range(s) of External Identifiers, or range(s) of External Group Identifiers, or the domain names served by the NEF, in the case of NEF.
NOTE 5: This is applicable when NEF exposes AF information for analytics purpose as detailed in TS 23.288 [86].
NOTE 6: It is expected service authorization information is usually provided by OA&M system, and it can also be included in the NF profile in the case that e.g. an NF instance has an exceptional service authorization information.
NOTE 7: The NRF may store a mapping between UDM Group ID and SUPI(s), UDR Group ID and SUPI(s), AUSF Group ID and SUPI(s) and PCF Group ID and SUPI(s), to enable discovery of UDM, UDR, AUSF and PCF using SUPI, SUPI ranges as specified in clause 6.3 or interact with UDR to resolve the UDM Group ID/UDR Group ID/AUSF Group ID/PCF Group ID based on UE identity, e.g. SUPI (see clause 6.3.1 for details).
- IP domain list as described in clause 6.1.6.2.21 of TS 29.510 [58], Range(s) of (UE) IPv4 addresses or Range(s) of (UE) IPv6 prefixes, in the case of BSF.
- SCP Domain the NF belongs to.
