RICSubscriptionManagement


Used to establish E2 subscriptions on the E2 node consisting of an event trigger and a sequence of actions.



OpenModelOperation

·         isOperationIdempotent:  false

·         isAtomic:  false

·         support: MANDATORY



RIC Indication


Used to carry messages from a specific RAN Function to the RIC resulting from a REPORT or INSERT Action



OpenModelOperation

·         isOperationIdempotent:  false

·         isAtomic:  false

·         support: MANDATORY



NearRTRICServiceReport


Near-RT RIC requests that E2 NODE sends a REPORT message to Near-RT RIC and the associated procedure continues in E2 NODE after each occurrence of a defined SUBSCRIPTION
The REPORT service involves following steps:
1.            Near-RT RIC configures a SUBSCRIPTION in the E2 NODE with information used to configure an INDICATION (Report) that is to be performed by E2 NODE with each occurrence of trigger event
2.            During normal functioning of the E2 NODE, a trigger event is detected.
3.            E2 NODE sends INDICATION to Near-RT RIC containing requested REPORT information along with originating Request ID.
4.            Normal functionality continues on the E2 NODE.



OpenModelOperation

·         isOperationIdempotent:  false

·         isAtomic:  false

·         support: MANDATORY



NearRTRICServiceInsert


Near-RT RIC requests that E2 NODE sends an INSERT message to Near-RT RIC and suspends the associated procedure in E2 NODE after each occurrence of a defined SUBSCRIPTION
The INSERT service involves following steps:
1.   Near-RT RIC configures a SUBSCRIPTION in the E2 NODE with information used to configure an INDICATION(Insert) along with a wait timer that is to be performed by E2 NODE with each occurrence of EVENT
2.            During normal functioning of the E2 NODE, a trigger event is detected.
3.            E2 Node sends INDICATION to Near-RT RIC containing requested INSERT information along with originating Request ID.
4.            E2 Node suspends or halts the associated procedure after a defined Wait period (wait may be set to zero).
This process may then be followed by either:
-              Near-RT RIC sends a CONTROL message to trigger a new associated procedure or resume suspended procedure using modified call state or information
-              Wait timer associated for suspended procedure expires, and original associated procedure continues or halted



OpenModelOperation

·         isOperationIdempotent:  false

·         isAtomic:  false

·         support: MANDATORY



NearRTRICServiceControl


Near-RT RIC sends a Control message to E2 Node to initiate or resume the suspended associated procedure in the E2 Node
The CONTROL service involves following steps:
1.            Near-RT RIC detects a trigger event. This step may be either triggered by a previous INDICATION sent by E2 Node or internal to Near-RT RIC
2.            Near-RT RIC performs action
3.            Near-RT RIC sends CONTROL request to E2 Node.  This step may contain an information used to identify a previous suspended call process and may request acknowledgement
4.            E2 NODE initiates or resumes a call process
5.            If requested, E2 Node sends a CONTROL Acknowledgement



OpenModelOperation

·         isOperationIdempotent:  false

·         isAtomic:  false

·         support: MANDATORY



NearRTRICServicePolicy


Near-RT RIC requests that E2 Node executes a specific POLICY during functioning of the E2 Node after each occurrence of a defined SUBSCRIPTION
The POLICY service involves following steps:
1.            Near-RT RIC configures a SUBSCRIPTION in the E2 NODE with information used to configure a POLICY that is to be performed by E2 NODE with each occurrence of trigger event
2.            During normal functioning of the E2 NODE, a trigger event is detected.
3.            E2 NODE modifies ongoing call process according to information contained in the POLICY description statement
4.            Normal functionality continues on the E2 NODE.

PNF Startup and Registration MnS Provider sends an asynchronous pnfRegistration event to a PNF Startup and Registration MnS Consumer after PnP to notify PNF Startup and Registration MnS Consumer of new PNF Startup and Registration MnS Provider to be managed



OpenModelOperation

·         isOperationIdempotent:  false

·         isAtomic:  false

SoftwarePackageNamingContent


PNF Software Package naming, content and format are vendor specific and do not require standardization in O-RAN.  A PNF Software Package may contain one or more files.  Some of the files in the Software Package may be optional for the PNF (example: a file that has not changed version).  The PNF is aware of the content and format of its available Software Packages and can determine which files it needs to download.
The softwarePackage Managed Object Class (MOC) contains attributes about a software package such as:  software package name, version, fileList, integrityStatus (valid, invalid, empty), runningState (active, passive), vendor, productName, softwareType (operational, factory), etc. This MOC is applicable to VNFs and PNFs and is a generic term that O-RAN will use to refer to the software available on the PNF rather than the legacy term of software slot.  On a PNF, a softwarePackage MOI corresponds to a hardware software slot.
The PNF creates one instance of softwarePackage for each software package supported concurrently on the PNF.  Typically, a PNF will have two softwarePackage MOIs for operational software; one with runningState = active and one with runningState = passive.  Some PNFs also have a softwarePackage MOI for the factory software which would be read only.  O-RAN may have PNFs that support more than one passive slot.  In this case the inventory query result would show multiple MOIs with runningState=passive.

3.1.1.6         ManagedElement class

Qualified Name: ORAN::ObjectClasses::ManagedElement

Description:

This IOC (Information Object Class) represents telecommunications equipment or TMN entities within the telecommunications network providing support and/or service to the subscriber.

An ME communicates with a manager (directly or indirectly) over one or more management interfaces for the purpose of being monitored and/or controlled. MEs may or may not additionally perform element management functionality.

An ME contains equipment that may or may not be geographically distributed. An ME is often referred to as a "Network Element".


A telecommunication equipment has software and hardware components. The IOC described above represents the case when the software component is designed to run on dedicated hardware component. In the case when the software is designed to run on ETSI NFV defined NFVI [15], the IOC description would exclude the NFVI component supporting the above mentioned subject software. A ManagedElement may be contained in either a SubNetwork or in a MeContext instance. A single ManagedElement may also exist stand-alone with no parent at all.


The ManagedElement IOC may be used to represent combined ME functionality (as indicated by the managedElementType attribute and the contained instances of different functional IOCs).

Single function ManagedElement IOC instances will have a 1..1 containment relationship to a function IOC instance (in this context a function IOC instance is an instance of an IOC derived from the ManagedFunction IOC). Multiple function ManagedElement instances will have a 1..N containment relationship to function IOC instances.


NOTE:   For some specific functional IOCs a 1..N containment relationship is permitted.  The specific functional entities are identified in the NRMs that define subclasses of ManagedFunction.

This class is abstract.
