Scope
This page discusses the possibilities for PM streaming. In D-Release a use case and effort driven PM streaming of non-standardized VES message was implemented.
Forward looking a (more) standardized way of PM streaming should be evaluated.
O-RAN OAM Interface
specificationSpecification
The O-RAN Operation and Maintenance Interface Specification v10.00 from June 2023 refers in chapter 6.3.2 Performance Data Streaming to the websocket protocol based on the requirements documented in 3GPP TS 28.550 v17.1.0 clause 5.2.3. With respect to the data model the specification references 3GPP TS 28.532 v17.3.0 clause 11.5.1.1.2.
Idea
- Data Model
- SerializationFormat : GPB ( > /[Google] Protocol Buffers )
- yang to GPB (https://en.wikipedia.org/wiki/Protocol_Buffers)
- Protocol
- HTTP2
