Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Relay wireless devices face challenges in effectively servicing end-user devices due to limited resources from donor access nodes and difficulty in determining a preferred donor access node among multiple nearby nodes, which affects coverage and throughput.
Innovation Solution
A method and system for donor selection in relay access nodes, where a relay access node identifies and evaluates nearby candidate donor access nodes based on reliability, resource, and radio characteristics to determine a preferred node that meets specific thresholds, ensuring high-quality service to end-user devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a relay wireless device connects to multiple donor access nodes, then the available throughput and service quality improve, but the difficulty in determining a preferred donor access node increases
Solution Approach 1:
The patent applies parameter changes by evaluating multiple donor access nodes based on specific characteristics including reliability characteristics (e.g., connection stability), resource characteristics (e.g., available bandwidth, computing resources), and radio characteristics (e.g., signal strength, interference levels). The relay wireless device compares these parameters across different donor nodes to systematically determine the preferred donor, transforming the complex selection process into a structured parameter-based evaluation that improves throughput while managing selection complexity.
2Area of stationary object
If relay wireless devices are deployed at coverage edges, then coverage area is improved, but the ability to effectively service end-user devices deteriorates due to limited donor resources
Solution Approach 1:
The patent implements dynamics by enabling relay wireless devices to dynamically select and switch between donor access nodes based on real-time evaluation of reliability, resource, and radio characteristics. This dynamic selection allows relay devices deployed at coverage edges to adapt to changing network conditions and resource availability, ensuring that end-user devices receive reliable service even when connected to edge locations with potentially limited donor resources. The system continuously monitors and adjusts donor node selection to maintain service quality.
3Productivity
If relay wireless devices operate in crowded areas with high device density, then available throughput to end-users improves, but the difficulty in determining preferred donor access node increases due to multiple nearby nodes
Solution Approach 1:
The patent addresses this contradiction by establishing a structured parameter-based evaluation framework that systematically compares multiple donor access nodes based on reliability characteristics, resource characteristics, and radio characteristics. This approach transforms the complex task of evaluating multiple nearby nodes in crowded areas into a manageable process of comparing specific parameters, enabling the relay wireless device to determine the preferred donor node efficiently while maximizing available throughput to end-user devices.

AI summary
A relay wireless device is configured to function as a relay on behalf of a donor access node. The relay wireless device determines a preferred donor access node from among a plurality of candidate donor access nodes based on a comparison with a number of thresholds for reliable and efficient provision of services to end-user wireless devices via the relay wireless device. Any access node that meets the threshold requirements is added to a list of candidate donor access nodes. The candidate donor access node that best meets the thresholds may be selected as the preferred donor access node, and a connection request submitted to the preferred donor access node.
