Hierarchical Closed Loop Coordination for Wireless Network Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, particularly in wireless networks, there is a challenge in coordinating multiple closed loop functions operating on the same managed entity, which can lead to conflicts and inefficient operation due to independent action without consideration of shared goals or hierarchical coordination.
Innovation Solution
The implementation of a hierarchical nested structure for closed loop functions, where higher hierarchy functions receive and process insights from lower hierarchy functions, enabling coordinated decision-making and conflict resolution through control messages that pause or unpause actions, and update objectives, ensuring aligned goals and efficient operation.

Engineering Contradiction Analysis
1Ease of operation
If multiple closed loop functions operate independently on the same managed entity, then each function can act autonomously without coordination overhead, but conflicts arise and operational efficiency deteriorates
Solution Approach 1:
The patent implements a hierarchical nested structure where closed loop functions are organized in tiers (first closed loop function, second closed loop function, etc.). Lower hierarchy functions operate autonomously within their scope while higher hierarchy functions provide coordination and resolve conflicts. This nesting allows autonomous operation at the operational level while maintaining reliability through hierarchical coordination, directly resolving the contradiction between independence and coordination reliability.
2Reliability
If closed loop functions are coordinated through hierarchical structure, then conflicts are resolved and goals are aligned, but coordination complexity increases
Solution Approach 1:
The patent segments closed loop functions into distinct hierarchical levels (first closed loop function, second closed loop function, third closed loop function) with clear division of responsibilities. Each level handles specific aspects of managed entities, with lower levels performing operational tasks and higher levels providing coordination. This segmentation reduces overall complexity by modularizing the system, allowing each component to be simpler while maintaining goal alignment through the hierarchical structure.
3Productivity
If lower hierarchy functions provide insights to higher hierarchy functions, then coordinated decision-making is enabled, but information flow complexity increases
Solution Approach 1:
The patent establishes feedback mechanisms where lower hierarchy functions (second closed loop function, third closed loop function) provide insights about managed entities to higher hierarchy functions (first closed loop function). This feedback enables coordinated decision-making by ensuring higher levels are informed about operational conditions, resource usage, and potential conflicts. The feedback mechanism is structured to maintain information flow efficiency while avoiding excessive complexity through targeted information sharing at appropriate hierarchical levels.

AI summary
The disclosure relates to an apparatus comprising means for: receiving, at a first closed loop function from a second closed loop function, one or more proposed actions to be taken by the second closed loop function with respect to a managed entity, the first and second closed loop functions operating on the managed entity; determining, at the first closed loop function, one or more further actions to be taken, wherein the determining is based on the at least the one or more proposed actions to be taken by the second closed loop function; and causing, by the first closed loop function, the determined one or more further actions to be taken.
