Solution Overview

Problem

Current frequency spectrum management systems do not support multiple access devices applying for the same band of white frequency spectrum, which is necessary for services like multimedia broadcast multicast (MBMS), limiting the utilization of white frequency spectrum resources.

Innovation Solution

A method and system that allows multiple access devices to apply for and utilize the same frequency band of white frequency spectrum by a controller sending application information to a database, receiving the assigned frequency band, and distributing it to the access devices, enabling centralized management and efficient resource allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the existing frequency spectrum application mechanism is used, then each Master can apply for different frequency bands, but multiple Masters cannot apply for the same frequency band simultaneously, limiting services like MBMS

Engineering Contradiction:
Improvesupport for multiple Masters applying for same frequency bandVSAvoidfrequency spectrum management mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a frequency spectrum management system as an intermediary between multiple Masters and the frequency spectrum resources. This mediator coordinates application information from multiple Masters, manages frequency band allocation, and enables multiple Masters to simultaneously access the same frequency band through centralized control and coordination, thereby resolving the contradiction between supporting multiple Masters and maintaining management simplicity

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If white frequency spectrum resources are allocated to multiple Masters for the same service, then resource utilization improves, but the existing mechanism does not support simultaneous application by multiple Masters for the same band

Engineering Contradiction:
Improvefrequency spectrum resource utilizationVSAvoidsupport for simultaneous multi-Master application
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The patent extends the frequency spectrum application mechanism to serve multiple Masters simultaneously for the same frequency band. The application information structure and management system are designed to handle universal cases where multiple Masters need to access the same resources, enabling services like MBMS that require multi-Master support while maintaining the existing single-Master functionality

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If a centralized frequency spectrum management system is implemented to allow multiple Masters to apply for the same band, then service support like MBMS is enabled, but the complexity of the management mechanism increases

Engineering Contradiction:
Improvesupport for MBMS and similar servicesVSAvoidfrequency spectrum management system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the frequency spectrum management function into distinct components: application information collection from Masters, application information processing by the management system, and frequency band allocation decisions. This segmentation allows the system to handle complex multi-Master scenarios while maintaining manageable complexity through modular architecture and clear functional separation

Inventive Principle:
Principle #1Segmentation
