Dynamic Data Split Control via Per-Connection Insertion Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, determining the optimal split ratio for dual-connectivity service and selecting the primary uplink path for dual-connected users is challenging due to variations in spectral efficiency, fading, insertion loss, beamforming support, MIMO capabilities, and aggregate frequency bandwidth across different connections.
Innovation Solution
A computing system dynamically controls the data split and primary uplink path by comparing metrics such as spectral efficiency, fading, insertion loss, beamforming support, MIMO support, and aggregate frequency bandwidth of the connections, setting split ratios and designating primary paths based on desirable and undesirable service characteristics.

1Reliability
If dynamic control of data split ratio is implemented based on multiple connection metrics, then communication quality and efficiency are improved, but system complexity increases
Solution Approach 1:
The system dynamically adjusts the data split ratio parameter between dual connectivity connections based on real-time comparison of multiple metrics including spectral efficiency, fading, insertion loss, beamforming support, MIMO support, and aggregate frequency bandwidth. This parameter change enables optimal resource allocation while managing system complexity through automated control.
2Productivity
If multiple connection metrics are monitored and compared, then data flow distribution is optimized, but measurement and detection difficulty increases
Solution Approach 1:
The system implements feedback mechanisms where connection metrics (spectral efficiency, fading, insertion loss, beamforming support, MIMO support, and aggregate frequency bandwidth) are continuously measured and fed back to the controller. Based on this feedback, the controller dynamically adjusts the data split ratio to optimize data flow distribution between dual connectivity connections.
3Ease of operation
If per-connection insertion loss is used as basis for dynamic control, then uplink path selection is improved, but loss of information increases
Solution Approach 1:
The system converts the harmful effect of insertion loss into a useful control parameter. By monitoring and comparing insertion loss values between different connections, the system dynamically selects the optimal uplink path and adjusts data split ratios. The insertion loss information that would otherwise be wasted is now utilized to improve uplink communication performance and reliability.

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 insertion loss of the first air-interface connection with a level of insertion loss 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.
