Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, dual-connectivity scenarios face challenges in optimizing communication speed between a UE's master node (MN) and secondary node (SN), leading to potential delays that can impact overall throughput and service quality.
Innovation Solution
A mechanism is introduced to evaluate communication delays between candidate pairs of MN and SN, selecting the pair with the lowest delay for dual-connectivity service setup, ensuring efficient data exchange and control signaling between the nodes.

Engineering Contradiction Analysis
1Loss of time
If dual-connectivity service is established without evaluating inter-access-node delay, then setup complexity is reduced, but communication delay between MN and SN increases
Solution Approach 1:
The patent applies preliminary action by evaluating and comparing inter-access-node delays between candidate MN-SN pairs before establishing dual-connectivity service. The computing system determines delays for multiple candidate pairs in advance, then selects the pair with the lowest delay, thereby proactively minimizing communication delay before service establishment rather than reacting after setup.
2Speed
If multiple candidate MN-SN pairs are evaluated for delay, then communication speed is optimized, but processing complexity increases
Solution Approach 1:
The patent applies parameter changes by using inter-access-node delay as the key selection parameter for choosing MN-SN pairs. The computing system varies the delay parameter across multiple candidate pairs, identifies the pair with the minimum delay value, and selects that pair for dual-connectivity service, thereby optimizing data transmission speed through parameter-based selection.
3Productivity
If the lowest delay pair is selected for dual-connectivity, then throughput is improved, but selection process complexity increases
Solution Approach 1:
The patent applies self-service by enabling the computing system to autonomously evaluate inter-access-node delays for multiple candidate MN-SN pairs, compare the delay values, and automatically select the pair with the lowest delay without requiring manual intervention. This self-service mechanism improves overall throughput while keeping the selection process manageable through automation.

AI summary
A method and system to control configuration of dual-connectivity service a user equipment device (UE), wherein the dual-connectivity service including the UE being served concurrently by a master node (MN) over a first connection and by a secondary node (SN) over a second connection. An example method includes (i) identifying multiple pairs of access nodes as candidate pairs of access nodes to be the MN and SN for the dual-connectivity service, (ii) for each identified pair, determining an inter-access-node communication delay, (iii) comparing the determined inter-access-node communication delays of the identified pairs and, based on the comparing, selecting one of the identified pairs to be the MN and SN for the dual-connectivity service, and (iv) causing the dual-connectivity service to be set up for the UE with the selected pair of access nodes being the MN and SN for the dual-connectivity service.
