Radio Access Network Measurement Reporting with Priority Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio access network nodes face challenges in obtaining necessary measurements from other nodes for training or executing machine learning models, particularly in prioritizing and managing requests for measurements due to limited resources and varying priorities.
Innovation Solution
A method where a first radio access network node requests measurements from a second node by including priority information in the request message, allowing the second node to determine which measurements to provide based on priority levels, and sending a response indicating whether the requested measurements can be provided, enabling partial success in data reporting if not all measurements are available.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a radio access network node requests multiple measurements from another node, then the quantity of information obtained increases, but the resource burden on the responding node increases
Solution Approach 1:
The patent applies partial action by enabling the requesting node to specify only the measurements it actually needs through a filtered measurement list, rather than requesting all possible measurements. The responding node then provides only the requested measurements, reducing unnecessary resource consumption while ensuring sufficient information availability for machine learning model training.
2Reliability
If priority information is included in measurement requests, then measurement prioritization capability improves, but message complexity increases
Solution Approach 1:
The patent applies local quality by attaching priority information only to specific measurement items rather than to the entire request message. Each measurement in the filtered list can have an associated priority level, allowing fine-grained prioritization of individual measurements without complicating the overall message structure. This enables reliable measurement selection while maintaining message simplicity.
3Loss of information
If the responding node processes all requested measurements, then information completeness improves, but processing time increases
Solution Approach 1:
The patent applies the extraction principle by allowing the requesting node to pre-filter and select only the specific measurements it needs from the full set of available measurements. The responding node then extracts and provides only these selected measurements rather than processing all possible measurements, reducing processing time while maintaining completeness for the requested information.

AI summary
Disclosed is a method comprising transmitting, by a first radio access network node, to a second radio access network node, a request message for requesting one or more measurements, wherein the request message comprises priority information indicating a priority level per a measurement of the one or more measurements; and receiving, by the first radio access network node, from the second radio access network node, a response message indicating whether or not at least one of the one or more measurements can be provided from the second radio access network node.
