The present document studies compatibility of the ONAP management platform architecture and functionality with that of the 5G service-based management architecture being defined in 3GPP TS 28.53x, 28.54x and 28.55x series specifications. The present document is based on ONAP releases up to and including R3 ("Casablanca") and the corresponding APIs and related interfaces. The scope of the present document includes:

• analysis and comparison of 3GPP and ONAP configuration management mechanisms.
• analysis of how ONAP configuration management mechanisms can be supported in 3GPP.
• analysis and comparison of 3GPP and ONAP alarm management and performance management mechanisms, concentrating on DCAE (Data Collection, Analytics and Events) / Collection Framework event stream and batch data collection on the ONAP side.
• study how notify mechanisms are handled by ONAP DCAE and 3GPP management services.
• study if any gaps exist between the semantics and format of data collected by DCAE and the semantics and format of data produced by both alarm supervision and performance management services.
• analysis of ONAP/3GPP protocol compatibility.

The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

• References are either specific (identified by date of publication, edition number, version number, etc.) or non specific.
• For a specific reference, subsequent revisions do not apply.
• For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.
