Solution Overview

Problem

Existing systems fail to effectively manage sharable frequency resources, leading to poor usability due to interference between local and carrier network communications, as users cannot determine alternative conditions for frequency resource usage.

Innovation Solution

A management apparatus that estimates potential interference and notifies users of alternative conditions for frequency resource usage, allowing flexible adjustments such as changing output or TDD patterns to avoid interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the management apparatus permits usage of the frequency resource under the desired condition information, then the usability of the frequency resource is improved, but interference with the first wireless communication network occurs

Engineering Contradiction:

Improveusability of frequency resourceVSAvoidinterference with wireless communication

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The management apparatus changes parameters of the frequency resource usage conditions (such as transmission power, time slots, frequency bands) to find alternative configurations that satisfy both the usage applicant's needs and the interference constraints of existing networks

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The management apparatus provides feedback to the usage applicant by notifying alternative condition information when the desired conditions cannot be satisfied, enabling the applicant to adjust their usage parameters and resubmit requests under modified conditions

Inventive Principle:

Principle #23Feedback

2Ease of operation

If the management apparatus notifies alternative condition information, then the usability for usage applicants is improved, but the device complexity increases

Engineering Contradiction:

Improveusability for usage applicantVSAvoidcomplexity of management apparatus

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The management apparatus automatically performs impact estimation and generates alternative condition information without requiring manual intervention, enabling the system to serve itself in finding solutions while maintaining improved usability for applicants

Inventive Principle:

Principle #25Self-service

AI summary

There is provided a management apparatus configured to manage a sharable frequency resource. The management apparatus performs operations including: acquiring usage condition information on a usage condition for the frequency resource used by a first wireless communication network, and desired condition information on a condition under which a second wireless communication network desires to use the frequency resource; estimating, based on the usage and desired condition information, an impact imposed by the second wireless communication network on the first wireless communication network; determining whether to permit use of the frequency resource corresponding to the desired condition information in the second wireless communication network; and notifying alternative condition information on a usage condition, when the use of the frequency resource is determined to be not permitted.
