Interference Control Link-Up Device for Wireless Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In optical access services, a large number of wireless devices can cause unfair resource allocation and frequent unnecessary applications when controlling interference, as they freely issue usage requests without adjusting for frequency availability, leading to congestion and inefficiency.
Innovation Solution
An interference control system with a link-up device that processes resource applications and responses, updates a frequency availability table, and reflects this information in subsequent applications and responses to ensure fair allocation and reduce unnecessary requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless devices freely issue usage applications to the control device without adjustment, then resource allocation flexibility is improved, but fairness among subscribers deteriorates and unnecessary applications increase
Solution Approach 1:
The patent introduces a link-up device as an intermediary between wireless devices and the control device. This link-up device collects resource application information from multiple wireless devices, determines frequency availability based on interference calculations, and then issues adjusted usage applications to the control device on behalf of the wireless devices. This intermediary mechanism ensures that resource allocations are made fairly while reducing unnecessary applications.
Solution Approach 2:
The link-up device performs preliminary actions by collecting resource application information from wireless devices before actually issuing applications to the control device. It calculates interference, determines frequency availability in advance, and prepares adjusted usage applications that already account for fairness and congestion avoidance, preventing unnecessary applications from being issued.
2Speed
If wireless devices issue usage applications without checking frequency availability, then application processing speed is improved, but network congestion increases and efficiency deteriorates
Solution Approach 1:
The link-up device acts as a mediator that consolidates resource application information from multiple wireless devices and issues coordinated usage applications to the control device. This approach maintains processing speed by batching operations while improving network efficiency through intelligent frequency selection and interference management.
Solution Approach 2:
The system implements feedback mechanisms where the link-up device receives response information from the control device regarding frequency availability and interference levels. This feedback is used to adjust subsequent resource applications, ensuring that wireless devices do not repeatedly issue unnecessary applications for congested frequencies, thereby improving overall network efficiency.

AI summary
Provided is an interference control system for wireless communication suitable for limiting the total amount of interference given to an interfered device to be protected by a large number of interfering devices. The system provides a control device disposed in a public network with a resource application based on a message issued regarding use of a radio resource by an interfering device disposed in a carrier network. A response based on a message issued by the control device with respect to the resource application is provided to the interfering device that has issued the resource application. A resource table including information in which availability of frequency in carrier network is estimated is updated on the basis of the resource application and the response. The information in which the availability is estimated and included in the resource table is reflected in the resource application.
