RAN Node Resource Prediction via Intermediary Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks face challenges in managing radio resources effectively across Radio Access Network (RAN) nodes, particularly in predicting and exchanging resource utilization metrics, which hinders load balancing and radio resource management processes.
Innovation Solution
A method where a first RAN node obtains and predicts resource status information from a second node, allowing it to either use this information for resource management or send it to a third node, enabling indirect prediction and optimization of resource utilization across nodes without direct signaling connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If resource status information is exchanged directly between all RAN nodes, then measurement precision and resource management accuracy improve, but device complexity and signaling overhead increase
Solution Approach 1:
The patent introduces a first RAN node as an intermediary that collects resource status information from a second RAN node and provides predictions to a third RAN node. This mediator approach allows the third node to obtain resource status data without establishing direct signaling connections with the second node, thereby reducing signaling overhead and network complexity while maintaining measurement precision through the intermediary's prediction capabilities
Solution Approach 2:
The first RAN node creates a copy or representation of the resource status information from the second node and generates predictions based on this copied data. Instead of requiring direct access to original measurements, nodes can work with copied and processed information, reducing the need for multiple direct signaling connections while preserving the essential resource status data for decision-making
2Measurement precision
If historical resource status data is collected and analyzed, then prediction accuracy improves, but loss of time for data collection and processing increases
Solution Approach 1:
The first RAN node performs preliminary actions by continuously collecting and analyzing historical resource status information from the second node in advance. This preliminary data collection and analysis enable the node to generate predictions proactively, reducing the time required when actual resource management decisions need to be made, as the predictive models are already trained and ready to provide quick estimates
Solution Approach 2:
The system maintains continuous collection and analysis of resource status data, ensuring that predictive models are constantly updated with fresh information. This continuous action eliminates gaps in data availability and reduces processing delays, as the system is always in a state of readiness to provide accurate predictions without requiring intensive batch processing periods

AI summary
A method is disclosed for managing resources in a Radio Access Network (RAN) of a communication network. The method, performed by a first node in the RAN, comprises obtaining a record of resource status information describing usage, during a historical time period, of RAN resources controlled by a second node in the RAN and predicting, based on the obtained record, resource status information describing usage of RAN resources controlled by the second node during a future time period. The method further comprises performing at least one of using the predicted resource status information describing usage of RAN resources controlled by the second node in a process relating to management of RAN resources controlled by the first node, or sending, to a third node in the RAN, a representation of the predicted resource status information describing usage of RAN resources controlled by the second node.
