NWDAF Object Identifier Retrieval for Simplified OAM Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of obtaining data from an Operation, Administration, and Maintenance (OAM) system by a Network Data Analytics Function (NWDAF) is complex due to the need to manage an entire database of objects, which complicates data retrieval.
Innovation Solution
A method and system where a network data analytics network element determines an object identifier of a data source within the OAM system using association or generation rules, allowing it to send targeted requests for specific data without managing the entire database, simplifying the data retrieval process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the NWDAF manages an entire database of managed objects in the OAM system, then it can obtain any data from the system, but the data retrieval process becomes complex
Solution Approach 1:
The patent segments the monolithic database management approach into a targeted identifier-based retrieval system. Instead of managing the entire database, the NWDAF now uses specific object identifiers (such as network slice identifiers, cell identifiers, or gNB identifiers) to retrieve only the necessary data portions from the OAM system, thereby reducing process complexity while maintaining data access capability
Solution Approach 2:
The patent implements preliminary action by pre-establishing the association between NWDAF identifiers and OAM system object identifiers. This mapping relationship is set up in advance, allowing the NWDAF to directly retrieve data using pre-computed identifiers without needing to navigate or manage the entire database structure during data retrieval operations
Data Source
AI summary
A data obtaining method and system, and an apparatus thereof. A network data analytics network element determines a data source to which to-be-obtained data belongs. Based on first information, an object identifier that is of the data source and that is in an operation, administration, and maintenance OAM system is determined. The network element sends a first request to the OAM system. The first request includes the object identifier. The first request is for requesting to obtain the to-be-obtained data.
