Data Flow Manager for Link Quality Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication network architecture often results in poor link quality for user equipment due to the limitations of wireless local area networks provided by home gateways, which can degrade the overall communication link quality.
Innovation Solution
A data flow manager that distributes data streams across a composite communication link formed by a first communication link connecting a home gateway to a network access entity and a second communication link connecting the user equipment directly to another network access entity, dynamically adjusting data amounts based on link quality signals to optimize communication resources and maintain high link quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment connects via home gateway through wireless local area network, then network access is provided, but link quality deteriorates due to gateway limitations
Solution Approach 1:
The patent segments the data stream into multiple parts and distributes them across different communication paths: one path through the home gateway (first communication link) and another path directly to the network access entity (second communication link). This segmentation allows the system to bypass the gateway's limitations for critical data while still utilizing the gateway for other traffic, thereby improving overall link quality without completely abandoning the gateway infrastructure.
Solution Approach 2:
The patent introduces a data flow manager as an intermediary component that intelligently controls data distribution between the two communication paths. This mediator monitors link quality metrics and dynamically adjusts the proportion of data sent through each path, resolving the contradiction by finding an optimal balance between using the gateway (for connectivity) and bypassing it (for quality).
2Reliability
If data is distributed across multiple communication links, then link quality is improved, but system complexity increases
Solution Approach 1:
The data flow manager is designed as a multi-functional component that performs multiple tasks: it monitors link quality on both communication paths, dynamically adjusts data distribution ratios, manages connection states, and optimizes resource allocation. By consolidating these diverse functions into a single universal manager, the patent reduces overall system complexity while maintaining the benefits of multi-path data distribution.
Solution Approach 2:
The system implements continuous feedback loops where the data flow manager monitors link quality metrics from both communication paths and uses this feedback to dynamically adjust the data distribution strategy. This closed-loop control automates the complexity of managing multiple paths, allowing the system to adapt to changing conditions without requiring complex manual configuration or intervention.
3Productivity
If data stream is transmitted through home gateway, then network access is achieved, but communication resources are insufficient
Solution Approach 1:
The patent adds another dimension to the communication architecture by introducing a parallel data path that bypasses the home gateway. Instead of relying solely on the single resource-constrained path through the gateway, the system creates a second dimension of data flow directly to the network access entity, effectively increasing the total available communication resources and transmission capacity.

AI summary
A data flow manager for distributing data of a data stream of a user equipment via a first communication link and via a second communication link includes: a network interface configured to receive a first status signal indicating a link quality of the first communication link, a second status signal indicating a link quality of the second communication link and a third status signal indicating a link quality of a composite communication link; and a processor configured to, if at least one of the first status signal or the second status signal indicates a higher link quality than a link quality that is indicated by the third status signal, determine a reduction of an amount of data of the data stream communicated over the first communication link and an increase of an amount of data of the data stream communicated over the second communication link.
