Solution Overview
Problem
Control actions in wireless communication networks, such as frequency band scanning or Wi-Fi sensing, disrupt communications between nodes, causing varying degrees of service quality degradation.
Innovation Solution
A method and device for managing node configurations in a wireless network, where a controller node anticipates disruptions by modifying multi-link connections before executing control actions, using information about scheduled control actions and node statuses to coordinate configuration changes.

Engineering Contradiction Analysis
1Extent of automation
If control actions (frequency band scanning, Wi-Fi sensing) are executed on wireless network nodes, then network control and monitoring capabilities are improved, but communication quality and service reliability deteriorate due to disruptions on affected frequency bands
Solution Approach 1:
The controller node proactively modifies the configuration of multi-link connections before executing control actions. Specifically, it removes authorization to transmit and receive data on frequency bands that will be affected by upcoming control actions (such as frequency band scanning or Wi-Fi sensing), thereby preventing communication disruptions before they occur. This preliminary configuration change ensures that control actions can be executed without degrading communication quality.
Solution Approach 2:
The patent segments the frequency bands used in multi-link connections by removing authorization for specific frequency bands that will be affected by control actions. This allows the network to maintain communication on unaffected frequency bands while isolating the impact of control actions to only the segments (frequency bands) that are being controlled or monitored, thus preserving overall communication reliability.
2Reliability
If multi-link connections using distinct frequency bands are established between nodes, then communication robustness and data transmission capability are improved, but configuration management complexity increases
Solution Approach 1:
The controller node acts as an intermediary that centrally manages the configuration of multi-link connections between wireless network nodes. It maintains awareness of which frequency bands are used in which connections and coordinates configuration changes across multiple nodes. This centralized mediation simplifies the complexity of managing multi-link connections by providing a single point of control that can proactively adjust configurations before control actions are executed.
3Reliability
If controller node proactively modifies connection configurations before control actions, then communication disruption is minimized, but network control complexity and processing overhead increase
Solution Approach 1:
The controller node implements a feedback mechanism where it receives information about scheduled control actions from wireless network nodes and responds by proactively modifying connection configurations. This feedback loop allows the controller to make informed decisions about which frequency bands need protection from disruptions, enabling targeted configuration changes rather than blanket restrictions, thus balancing communication continuity with controlled processing overhead.

AI summary
A method for managing a configuration of a plurality of nodes of a wireless communication network controlled by a controller node is disclosed that obtaining information relating to a control action on one of the frequency bands, scheduled to be executed by an executing node, transmitting, to an impacted node, of the plurality of nodes including the executing node, the impacted node having established at least one multi-link connection with at least one other node, a request to modify the configuration of the at least one connection, for a link of the multi-link connection using the frequency band, the configuration modification being a function of the control action; and upon receipt, from the impacted node, of a confirmation of configuration modification of the at least one connection, transmitting information to the controller node indicating that the scheduled control action on the frequency band is ready to be executed.
