Introduction

The O-RAN Alliance and the O-RAN-Software Community specifying and developing and implementing a couple of management and control interfaces which are aligned with 3GPP specifications. In accordance with the O-RAN Operation and Maintenance Architecture v1 and Interface Specification v1,  for the O1 Interface, a data model for the protocol NetConf is required. 3

In June 2019, 3GPP published the Network Resouce Model (TS 28.541 version 16.1.0). This model includes yang specification, which could/should be used by O-RAN Alliance and O-RAN-SC.

The yang modules were separated from the word document to be analyzed further ( OAM-9 - Sæki upplýsingar um mál… STAÐA ).

Please consider this page as preparation for feedback, liaison, contribution to 3GPP.

Formal

Providing yang modules

Public access to yang modules would be very benifical, avoiding error prune and time consuming extraction from from word documents. 

... are good candidates to publish agreed and reviewed 3GPP yang modules.


YANG mechanics

Revision in import statements

The "revision date" in yang import statements should be avoided to gain more flexibility, when the imported yang module is update. It avoids updates of the importing yang model.

TS 28.541 v16.1.0 exampleProposal
submodule ngc-UDRFunction {
    
	belongs-to ngc { prefix ngc; }
    
	import EP_RP { prefix ep-rp; revision-date "2018-07-31"; }
    import ManagedFunction { prefix mf; revision-date "2018-07-31"; }
    import nrm-types-3gpp { prefix nrm-type; revision-date "2018-07-31"; }
    import ietf-inet-types { prefix inet; revision-date "2010-09-24"; }  
submodule ngc-UDRFunction {
    
	belongs-to ngc { prefix ngc; }
    
	import EP_RP { prefix ep-rp }
    import ManagedFunction { prefix mf }
    import nrm-types-3gpp { prefix nrm-type }
    import ietf-inet-types { prefix inet }
