1Device complexity

If carrier aggregation is implemented with fixed primary and secondary serving cell relationships, then network configuration is simplified, but carrier aggregation utilization is reduced due to misaligned cell boundaries

Engineering Contradiction:

Solution Approach 1:

The patent implements dynamic reconfiguration of primary and secondary serving cell relationships based on real-time network conditions and UE locations. The network node monitors cell boundary alignments and dynamically adjusts serving cell relationships to maximize carrier aggregation opportunities, transforming the static configuration into an adaptive system that responds to changing conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the serving cell relationship parameters dynamically by reconfiguring which cells serve as primary and which serve as secondary based on computed alignment metrics. This parameter adjustment allows the network to optimize carrier aggregation utilization without requiring complete redesign of the network architecture.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If serving carriers are configured to cover overlapping geographical areas, then carrier aggregation capability is maximized, but network resource utilization becomes inefficient when cell boundaries do not align

Engineering Contradiction:

Improvedata throughputVSAvoidnetwork resource efficiency

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The network node computes carrier aggregation utilization statistics and uses this feedback to determine when reconfiguration is needed. By continuously monitoring utilization metrics and comparing them against thresholds, the system receives feedback about actual performance versus potential performance, enabling data-driven decisions about when to reconfigure serving cell relationships.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system automatically detects misalignment issues and performs self-reconfiguration without requiring manual intervention. The network node autonomously computes the optimal serving cell relationships and executes reconfiguration, allowing the network to self-optimize carrier aggregation utilization based on real-time conditions.

Inventive Principle:

Principle #25Self-service

Core Design Contradiction:

Solution Approach 1:

The patent segments the network control function by separating the computation of serving cell relationships from the execution of reconfiguration. The network node computes optimal relationships based on utilization statistics, then executes reconfiguration only when thresholds are met, dividing the control logic into discrete, manageable segments rather than continuous complex processing.

Inventive Principle:

Solution Approach 1:

The system performs preliminary computation of optimal serving cell relationships based on initial network deployment data and utilization statistics. By pre-computing and storing optimal configurations, the system prepares reconfiguration plans in advance, reducing the time needed for manual optimization during deployment and enabling faster network setup.

AI summary

Dynamic carrier aggregation cell relationship management systems and methods are provided. In some embodiments, carrier aggregation relationship configuration logic computes carrier aggregation utilization statistics for primary serving cell and secondary serving cell relationship configurations. The logic further reconfigures primary serving cell to secondary serving cell relationships based on the utilization statistics to provide carrier aggregation coverage to user equipment that most efficiently utilizes the extra bandwidth made available by activating a secondary serving cell for carrier aggregation. The ability to dynamically reconfigure primary service cell to secondary service cell relationships improves carrier aggregation utilization, reduces congestion, and improves network resource utilization.
