Communication Control Device for Secondary Service Resource Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple secondary communication services operate without cooperation, there is a risk of interference and inefficient frequency usage, as existing technologies lack effective methods for adjusting radio access techniques and channels to share communication resources.
Innovation Solution
A communication control device that receives access technique information from secondary usage nodes and determines whether communication resources can be shared based on radio access techniques, allowing for resource sharing even when interference levels exceed acceptable limits, by using OFDMA or CSMA techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple secondary usage nodes operate independently without cooperation, then each node can provide second communication services using the frequency band, but interference and signal collision occur between services and frequency usage efficiency is poor
Solution Approach 1:
A communication control device is introduced as an intermediary between secondary usage nodes. This mediator receives access technique information from multiple secondary usage nodes, determines whether communication resources can be shared based on radio access techniques, and coordinates resource allocation. The intermediary enables cooperative operation while preventing interference and signal collision between independent nodes.
2Ease of manufacture
If multiple second communication services are provided separately without cooperation, then service deployment is simple, but frequency usage efficiency is difficult to improve
Solution Approach 1:
The communication control device implements a feedback mechanism where secondary usage nodes report access technique information to the control device, which then determines resource shareability and provides coordination decisions. This feedback loop enables automatic optimization of frequency usage efficiency while maintaining simple service deployment through centralized control.
3Productivity
If communication resources are shared between services with overlapping service areas, then frequency usage efficiency is improved, but complex determination of resource shareability is required
Solution Approach 1:
The system uses parameter-based determination for resource shareability by comparing radio access technique parameters between services. The communication control device determines whether communication resources can be shared based on specific parameters of radio access techniques (such as OFDMA or CSMA compatibility), enabling automated resource allocation without complex analysis of service area overlaps or interference patterns.
