Embodiments of the present disclosure describe methods and apparatuses for network resource modelling to support next generation node Bs.

## Claims

### Claim 1

One or more non-transitory, computer-readable media having instructions that, when executed by one or more processors, cause a network manager (“NM”) or network manager function (“NMF”) to:
generate and send a configuration management (“CM”) command to an element manager (“EM”) or element manager function (“EMF”) to create, modify, or delete an information object class (“IOC”) that is to represent a next generation node B (“gNB”), wherein the IOC is a gNB Function IOC to represent the gNB, a Central Unit (“CU”) IOC to represent a CU of the gNB, a Distributed Unit (“DU”) IOC to represent a DU of the gNB, or a next generation universal terrestrial radio access network (“GUTRAN”) Cell IOC to represent a GUTRAN cell to be provided by the gNB; and
process a response from the EM to determine a result of a CM operation performed based on the CM command.

### Claim 2 (depends on 1)

The one or more non-transitory, computer-readable media of claim 2, wherein the gNB Function IOC contains the CU IOC and the DU IOC and further contains the GUTRAN Cell IOC to represent the GUTRAN cell.

### Claim 4 (depends on 3)

The one or more non-transitory, computer-readable media of claim 3, wherein the gNB Function IOC contains the CU IOC, which contains the DU IOC.

### Claim 5 (depends on 1)

The one or more non-transitory, computer-readable media of claim 1, wherein the IOC is contained by a Managed Element IOC and is the CU IOC or the DU IOC.

### Claim 6 (depends on 5)

The one or more non-transitory, computer-readable media of claim 5, wherein the IOC is the CU IOC and the Managed Element IOC also contains the DU IOC.

### Claim 7 (depends on 6)

The one or more non-transitory, computer-readable media of claim 6, wherein the CU IOC contains the GUTRAN Cell IOC.

### Claim 8 (depends on 5)

The one or more non-transitory, computer-readable media of claim 5, wherein the IOC is the CU IOC that contains the DU IOC.

### Claim 9

One or more non-transitory, computer-readable media having instructions that, when executed, cause a network manager (“NM”) or a network manager function (“NMF”) to:
generate a request to establish a relationship between a virtual network function (“VNF”) instance and a physical network function (“PNF”) instance to form a next generation node B (“gNB”), wherein the VNF instance is to provide a centralized unit of the gNB and the PNF instance is to provide a distributed unit of the gNB;
cause the request to be sent to an element manager (“EM”) or an element manager function (“EMF”); and
process a response to the request, the response to indicate whether the relationship was established.

### Claim 10 (depends on 9)

The one or more non-transitory, computer-readable media of claim 9, wherein the response is to indicate that the relationship was not established.

### Claim 11 (depends on 10)

The one or more non-transitory, computer-readable media of claim 10, wherein the response is to include a cause as to why the relationship was not established.

### Claim 12 (depends on 9)

The one or more non-transitory, computer-readable media of claim 9, wherein the response is to indicate that the relationship was established.

### Claim 13 (depends on 9)

The one or more non-transitory, computer-readable media of claim 9, wherein the request is to establish a relationship between the VNF instance and a plurality of PNF instances, wherein the plurality of PNF instances are respectively associated with a corresponding plurality of gNBs.

### Claim 14

One or more non-transitory, computer-readable media having instructions that, when executed, cause an element manager (“EM”) or an element manager function (“EMF”) to:
process a request to establish a relation between a virtual network function (“VNF”) instance and a physical network function (“PNF”) instance to form a next generation node B (“gNB”), wherein the VNF instance is to provide a centralized unit of the gNB and the PNF instance is to provide a distributed unit of the gNB;
determine whether the relation between the VNF instance and the PNF instance is valid;
