RAN Node Registration via AMF and NRF for Analytics Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for wireless communications systems are inadequate in analytics collection and analysis, particularly in radio access network (RAN) node registration and discovery, leading to inefficiencies in data management and analytics processing.
Innovation Solution
The implementation of an Access and Mobility Management Function (AMF), Network Data Analytics Function (NWDAF), Unified Data Management Function (UDM), and Network Repository Function (NRF) to facilitate RAN node registration, data collection, and analytics processing, enabling efficient identification and querying of RAN entities for analytics requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional analytics collection methods are used in wireless communications systems, then existing data management processes can be maintained, but analytics processing efficiency and RAN node discovery capability are insufficient
Solution Approach 1:
The system segments RAN node information management into distinct functional components: the AMF handles registration and profile management, the NRF stores and retrieves node profiles, and the NWDAF performs analytics processing. This segmentation enables efficient specialized processing at each stage, improving overall analytics productivity while ensuring comprehensive information availability through distributed storage and retrieval capabilities.
2Adaptability or versatility
If RAN node registration and discovery procedures are implemented, then RAN entity identification capability is improved, but network function complexity increases
Solution Approach 1:
The AMF performs multiple functions including RAN node registration, profile management, and coordination with both NRF and NWDAF. The NRF serves as a universal repository for RAN profiles that can be queried by multiple network functions. This multi-functionality approach enables comprehensive RAN entity identification capability while avoiding the complexity of implementing separate specialized functions for each task.
3Reliability
If analytics data collection requests are transmitted to multiple RAN nodes, then analytics information completeness is improved, but network signaling overhead increases
Solution Approach 1:
The system performs preliminary actions by having the AMF pre-register RAN node profiles in the NRF before analytics collection is needed. When the NWDAF requires analytics data, it queries the NRF to obtain the list of registered RAN nodes, then selectively requests data only from relevant nodes. This preliminary registration approach ensures complete analytics information can be collected while minimizing signaling overhead by avoiding unnecessary data requests from unrelated nodes.

AI summary
Methods, systems, and devices for wireless communications are described. An access and mobility management function (AMF) may register a configuration of one or more RAN entities to a network repository function (NRF). The AMF may register information associated with a device with a UDM. A network data analytics function (NWDAF) may perform RAN discovery via the NRF, the UDM, or both. The NWDAF may receive an analytics request from a device, and the NWDAF may query the NRF, the UDM, or both for information about one or more targets of the analytics request, and the NWDAF may receive such information from the NRF, the UDM, or both. The NWDAF may transmit a data collection request to the RAN and the NWDAF may receive data back from the RAN.
