O-RAN O1 Interface Specification specifies the format of the CM Notification VES message sent from the RAN NF (e.g, CU, DU) to the SMO. The SMO has collectors to receive the VES message, which is forwarded to appropriate SMO Functions to update any relevant CM control algorithm and any relevant database. In the London release, we plan to build on existing work and achieve the following for INT-2177 - Getting issue details... STATUS
- Define a CM Notification VES format aligned with the latest consensus in O-RAN, OSC, 3GPP
(e.g. O1 spec v08.00, 3GPP Rel 18
see OpenAPI/TS28532_ProvMnS.yaml · Rel-18 · SA5 – Management & Orchestration and Charging / Management and Orchestration APIs · GitLab (3gpp.org)
ref thanks to Martin Skorupski ) - Define an efficient, model-driven path to identify the MOI and attribute whose value has been changed
(e.g. use notifyMOIAttributeValueChanges or notifyMOIChanges as appropriate)
Relevant background on this topic.
- OSC work on CM Handling (Nov 2021). The following page
CM handling guide - Developer Wiki - Confluence (onap.org)
describes a CM VES message and procedure for handling it, especially mapping the schema url to a local url. This refers to a 3GGP Rel16 scheme which needs to be updated to https://forge.3gpp.org/rep/sa5/MnS/-/blob/Rel-18/OpenAPI/TS28532_ProvMnS.yaml - ONAP work on defining a CM VES message. This is an older format and does not have a path specified, but may be useful in designing the solution
