To support management and orchestration of 5G networks, the Network Resource Model (NRM) is an information model representing the manageable aspects of 5G networks. The NRM needs to be defined, according to 5G network specifications from other 3GPP working groups as well as considering requirements for the 5G management architecture and operations.
A Network Resource is a component which can be identified as a discrete entity and is in an object-oriented environment for the purpose of management represented by an abstract entity called Information Object Class (IOC).
IOCs, attributes of an IOC and relationships between IOCs are defined in the NRM.
This paper describes how the 5G NRM is specified in 3GPP in three stages including requirements, information service and solution set definitions.
