5A.2.1.1 Relationships
The set of classes (e.g. IOCs) that encapsulate the information relevant for IMS network resource information for telecommunication network management purposes are described in TS 28.705 [72].
The set of classes IOC EP_RP for SBA support of SCSCFFunction, HSSFunction, PCSCFFunction and PCFFunction are described in this clause.
The Figure 5A.2.1.1-1 shows the transport view of SCSCFFunction NRM for SBA interfaces.
