Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, there is a challenge in dynamically controlling dual-connectivity service, particularly in determining the optimal split ratio for downlink and uplink data flow and selecting the primary uplink path between 4G and 5G connections, as existing methods lack efficient metrics for comparing spectral efficiency, fading, insertion loss, beamforming support, and MIMO support across different connections.
Innovation Solution
A computing system dynamically controls dual-connectivity by comparing metrics such as spectral efficiency, fading, insertion loss, beamforming support, and MIMO support across 4G and 5G connections to set split ratios and determine the primary uplink path, optimizing data flow distribution based on desirable and undesirable service characteristics.

Engineering Contradiction Analysis
1Adaptability or versatility
If dual-connectivity service is implemented with 4G and 5G connections, then network coverage and service availability are improved, but determining optimal split ratio and primary uplink path becomes complex due to lack of efficient comparison metrics
Solution Approach 1:
The patent applies parameter changes by introducing a comprehensive metric system that transforms multiple connection characteristics (spectral efficiency, fading, insertion loss, beamforming support, MIMO support) into comparable quantitative parameters. This enables dynamic adjustment of split ratios and primary uplink path selection based on real-time metric comparisons, resolving the complexity of dual-connectivity control through standardized parameter evaluation.
2Productivity
If data flow is distributed across multiple connections, then overall data rate and service quality are improved, but signal degradation and interference increase without optimal path selection
Solution Approach 1:
The patent implements feedback mechanisms by continuously monitoring connection metrics (spectral efficiency, fading, insertion loss, beamforming support, MIMO support) and using this information to dynamically adjust data flow distribution. The system compares metrics between 4G and 5G connections in real-time, providing feedback that guides optimal split ratio determination and primary uplink path selection, thereby maximizing data rate while minimizing signal degradation through informed routing decisions.
3Productivity
If dynamic control of split ratio is implemented, then data transmission efficiency is improved, but measurement and comparison of multiple metrics becomes more difficult
Solution Approach 1:
The patent applies universality by creating a multi-functional metric comparison framework that simultaneously evaluates multiple connection characteristics (spectral efficiency, fading, insertion loss, beamforming support, MIMO support) through a unified measurement approach. This universal metric system enables comprehensive assessment of 4G and 5G connections using consistent evaluation criteria, simplifying the detection and measurement process while enabling sophisticated dynamic control of data flow distribution for optimized transmission efficiency.

AI summary
A method and system for controlling data split of a dual-connected user equipment device (UE) when the UE has at least two co-existing air-interface connections including a first air-interface connection with a first access node and a second air-interface connection with a second access node. An example method includes (i) comparing a level of beamforming support of the first air-interface connection with a level of beamforming support of the second air-interface connection, (ii) based at least on the comparing, establishing a split ratio that defines a distribution of data flow of the UE between at least the first air-interface connection and the second air-interface connection, and (iii) based on the establishing, causing the established split ratio to be applied. Further the method could include using the comparison as a basis to set one of the UE's air-interface connections as the UE's primary uplink path.
