Solution Overview

Problem

Existing network optimization techniques in broadband cellular networks struggle to effectively model complex dependencies and optimize network resources across multiple levels, leading to inefficiencies and suboptimal performance due to a lack of hierarchical structure in graph neural networks (GNNs) and excessive data communication overhead.

Innovation Solution

Implement a hierarchical graph representation using graph neural networks (GNNs) to model multi-level network optimization, incorporating a super graph that pools information from lower layers to upper layers, enabling efficient decision-making and optimizing network parameters across different timescales.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing network optimization techniques are used, then network resources can be managed, but complex dependencies cannot be effectively modeled and hierarchical structure is lacking

Engineering Contradiction:
Improveability to model complex dependenciesVSAvoidhierarchical structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The network is segmented into multiple hierarchical levels (e.g., cell level, district level, regional level), where each level processes information independently before aggregating to the next level. This segmentation allows the system to model complex dependencies at each level while maintaining overall manageability through the hierarchical structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a hierarchical dimension to the network optimization problem, transforming a flat network representation into a multi-level hierarchical structure. This dimensional change enables the system to capture complex dependencies across different scales of the network while organizing computation in a structured manner.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Measurement precision

If detailed node information is processed across the entire network, then optimization accuracy improves, but data communication overhead increases

Engineering Contradiction:
Improveoptimization accuracyVSAvoiddata communication overhead
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent extracts and processes information in a hierarchical manner, where each level extracts relevant features from its local nodes and passes aggregated representations to the next level. This extraction approach maintains optimization accuracy by preserving essential information while reducing the volume of data that needs to be communicated across the entire network.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Information from multiple nodes at the same hierarchical level is merged and aggregated before being passed to the next level. This merging process reduces data communication overhead by consolidating redundant information while maintaining the essential patterns and dependencies needed for accurate optimization decisions.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A system can produce a first graph that represents components of a broadband cellular network, wherein the first graph comprises first nodes and first edges. The system can process the first graph with a graph neural network to produce a feature embedding matrix. The system can pool information of nodes of the first graph based on the feature embedding matrix, to produce a second graph, wherein the second graph comprises second nodes and second edges. The system can adjust a parameter of a network controller of the broadband cellular network based on the second graph.
