DRAFT!
Open: All the details about the NetConf operation (rpc, edit-config (Create-MOI, Modify-MOI)).
Scope
A new function should be defined by WG1 for O-RAN-OAM-Interface specification (O1-interface) version 2.
The function should provide the ability by the Management-Service-Consumer (MnS Consumer, NMS) to subscribe and unsubscribe for VES events.
O1 Component Architecture
According to the O-RAN-OAM-interface specification (O1) each MnS Provider (ME) implements a (TLS/)NetConf interface for Configuration Management and consumes TLS/HTTP-POST messages with a json body in VES message format.
The method for the VES subscription/un-subscription must be performed via NetConf, because VES itself does not provide such function. The MnS Consumer will use the NetConf interface for such operation.
