Method and Apparatus to Encode RAN OAM-Related Data Over the R1 and Other O-RAN Open Interfaces Using Generic Data Encoding Model and Information Semantics
A method for providing generic information encoding for RAN OAM-related data by providing semantics of RAN OAM data including CM/PM/Trace data and a generic information encoding model using Information Elements (IE) and/or IE structures that leverage the RAN semantics for encoding RAN OAM-related data using common message structures to encode any number of OAM-related RAN parameters, nested in hierarchical RAN structures to any depths enabling an R1 data consumer via a data customer computer to discover data capabilities of an R1 data producer that produces the RAN OAM-related data over an O-RAN-standardized R1 interface between rApps and Non-RT RIC/SMO platform functions.
1 . A method of information encoding for Radio Access Network Operations, Administration, and Maintenance (RAN OAM) related data via a computer comprising the steps of:
providing semantics of RAN OAM data (RAN semantics) comprising RAN OAM-related data to be used while exchanging information over standardized interfaces for inter-operability;
providing a generic information encoding model for encoding the RAN OAM-related data, the generic information encoding model using common message structures to encode OAM-related RAN parameters nested in RAN structures for exchanging Application Programming Interface (API) messages between R1 data producers and R1 data consumers,
wherein the generic information encoding model using Information Elements (IE) and/or IE structures leverage the RAN semantics;
enabling an R1 data consumer via a data customer computer to discover data capabilities of an R1 data producer that produces the RAN OAM-related data over an Open-RAN (O-RAN) standardized R1 interface between rApps and Non-RT RIC/service management and orchestration (SMO) platform functions.
2 . The method of claim 1 , further comprising using a transport protocol that is Representational State Transfer/JavaScript Object Notation (REST/JSON).
3 . The method of claim 1 , wherein the encoding model and IE structure is based on JavaScript Object Notation (JSON).
4 . The method of claim 1 , wherein the encoding model and IE structure is based on an open source Remote Procedure Call/Group-Based Policy (gRPC/GPB).
5 . The method of claim 1 , wherein the RAN OAM-related data includes Configuration Management (CM) data, and each CM data type supports one or more of the following data generation/reporting triggers: a) event-driven, and b) periodic.
6 . The method of claim 5 , wherein the CM data type supports event-driven data generation/reporting triggers, when an instance of the CM data type is created in an O-RAN NF, or when an instance of the CM data type is modified in an O-RAN NF, or when an instance of the CM data type is deleted in an O-RAN NF.
7 . The method of claim 5 , wherein when the CM data type supports periodic data generation/reporting triggers, a list of events related to the CM data type at a designated interval is reported.
8 . The method of claim 5 , wherein rApps are enabled to retrieve configuration schemes, read configuration data, and write configuration changes.

10 . The method of claim 9 , wherein when the PM data type supports periodic data generation/reporting triggers, a list of measurement IEs and supporting periodic triggers related to the PM data type at a designated interval is reported.
11 . The method of claim 9 , wherein rApps are enabled to query performance information.
12 . The method of claim 1 , wherein the RAN OAM-related data includes Trace Management (TM) data, and each TM data type supports one or more of the following data generation/reporting triggers: a) event-driven, and b) periodic.
13 . The method of claim 12 , wherein rApps are enabled to query alarm information, and change an alarm acknowledgement state.
14 . The method of claim 1 , wherein the RAN OAM-related data includes Fault Management (FM) data.
15 . The method of claim 14 , wherein RAN OAM-related functions register services produced with Service Management and Exposure (SME) Function for discovery by the rApps.
