The OAM project focus on the following topics:

Provide complete implementation for OAM functions (FCAPS).


The following Specifications needs to be considered for software updates:

O-RAN Operations and Maintenance Architecture Version 3.0 - April 2020

O-RAN Operations and Maintenance Interface Version 3.0 - April 2020

O-RAN Use Cases Detailed Specification 2.0 - April 2020

O-RAN Management Plane Specification Version 3.0 and YANG Models Version 3.0 - April 2020

VES JSON-Schemas

  • ONAP VES 7,2
  • 3GPP TS 28.532 V16.4.0
    • - A.1.2   JSON schema of ‘prov3gppFields’ for integration with ONAP VES
    • - A.2.2   JSON schema of ‘fault3gppFields’ for integration with ONAP VES

Yang Modules

New OAM related yang modules are avaialble by 3GPP and O-RAN WG4 OpenFronthaul v3.0

For O-RAN Members only :/ - please follow the DM discussions:

and of cause o-ran-hardware@2019-07-03.yang for the O-RAN identities.

Open: only for O-RU and O-DU; O-DU anyhow optional

Software Management

Management interfaces:

Use case:

Start with and xRan-fronthaul radio unit and perform and upgrade to an o-ru with the OpenFronthaul M-plane and upgrade further to an O-RU with an O-RAN/3GPP common O1 management interface.

Backup and restoreOpenROADM manifest file
xApp onboarding (from O1 point of view)under development by WG2 and Near-RT-RIC project
Subscription for VES


All this updates happens in ONAP CCSDK/SDNC and ONAP OOM project.

  • Switch to OpenDay version Sodium
  • Switch to Java11
  • https only support on all REST/RESTCONF interfaces 
    • O1-controller northbound
    • DMaaP
    • VES-Collector
  • full IPv6 support and integration tests on all SMO interfaces. 

  • No labels
