Section: 28.3.2.9 SMF Set FQDN
Content: An SMF Set within an operator's network is identified by its NF Set ID as defined in clause 28.12, with NFType set to "smf". For an SMF Set within an operator's PLMN, a subdomain name shall be derived from the MNC and MCC by adding the label "smfset" to the beginning of the Home Network Realm/Domain (see clause 28.2). The SMF Set FQDN shall be constructed as follows: set<Set Id>.smfset.5gc.mnc<MNC>.mcc<MCC>.3gppnetwork.org where - <MNC> = 3 digits - <MCC> = 3 digits If there are only 2 significant digits in the MNC, one "0" digit shall be inserted at the left side to fill the 3 digits coding of MNC in the AMF Set FQDN. - <Set Id> is the string representing the Set ID part within the NF Set ID defined in clause 28.12. EXAMPLE: "set12. smfset.5gc.mnc012.mcc345.3gppnetwork.org" (for the SMF set from MCC 345, MNC 12 and SetID "12") NOTE: The labels preceding the ".3gppnetwork.org" domain correspond to the NF Set ID definition in clause 28.12. For an SMF Set within an operator's Stand-alone Non-Public Network (SNPN), the SMF Set FQDN shall be constructed from its Network Identifier (NID), MNC and MCC or an SNPN domain name pre-configured in the NF, as follows: set<Set Id>.smfset.5gc.nid<NID>.mnc<MNC>.mcc<MCC>.3gppnetwork.org or set<Set Id>.smfset.<SNPN domain name> where - <MNC> and <MCC> shall be encoded as specified above; - NID shall be encoded as hexadecimal digits as specified in clause 12.7; - <SNPN domain name> is a domain name chosen by the SNPN operator. EXAMPLE: "set12.smfset.5gc.nid000007ed9d5.mnc012.mcc345.3gppnetwork.org" (for an SMF set from MCC 345, MNC 12, NID 000007ed9d5 (hexadecimal) and SetID "12")
