Information Processing Apparatus for Dynamic Radio Wave Resource Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The depletion of radio wave resources allocable to wireless systems has led to challenges in newly allocating radio wave resources, as all bands are already utilized by existing systems. Existing cognitive radio technologies struggle to effectively utilize free radio waves due to difficulties in sharing and managing radio wave resources among various users with different intentions.
Innovation Solution
An information processing apparatus is proposed that includes sections for acquiring identification information and regional information related to secondary use of a frequency band, acquiring information associated with control of secondary use by other wireless systems, generating information related to secondary use, and notifying external entities about this information. This apparatus facilitates efficient use of radio wave resources by providing insights into the current usage of free radio waves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cognitive radio technology is used to utilize free radio waves, then radio wave resource utilization is improved, but the ability to share and manage resources among multiple users with different intentions deteriorates
Solution Approach 1:
The patent introduces a notification system as an intermediary mechanism that enables multiple secondary users to share information about their usage of free radio waves. This mediator facilitates coordination and information exchange among users with different intentions, resolving the management complexity issue while maintaining high resource utilization through cognitive radio technology.
2Productivity
If information about secondary use of free radio waves is shared among multiple users, then resource allocation efficiency is improved, but confidentiality of secondary user information deteriorates
Solution Approach 1:
The notification system implements local quality by selectively sharing only the specific information necessary for resource allocation efficiency among users, while preserving the confidentiality of sensitive secondary user information. The system determines what information to notify based on local needs and requirements, achieving balanced information sharing.
3Reliability
If all radio wave bands are allocated to existing wireless systems, then service reliability of existing systems is improved, but availability of radio wave resources for new systems deteriorates
Solution Approach 1:
The patent implements a dynamic approach where secondary users can adaptively utilize free radio waves that become temporarily available from existing systems. The notification system enables real-time information exchange about available resources, allowing new systems to dynamically access radio wave bands without compromising the service reliability of existing primary users.
