Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spectrum management systems are inefficient and inflexible, leading to suboptimal use of electromagnetic spectrum, particularly in scenarios requiring dynamic priority adjustments between public safety, military, and mobile networks, which are often slow to adapt to changing communication demands during crises.
Innovation Solution
A method and system for dynamically allocating frequency ranges among multiple networks based on geographical area definitions, identifying and adjusting frequency parameters according to specific events and priorities, allowing for pre-agreed priority changes and tailored operations to ensure efficient and optimal spectrum use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed priority spectrum allocation is used, then regulatory stability is maintained, but spectrum utilization efficiency deteriorates during dynamic crisis situations
Solution Approach 1:
The system pre-establishes multiple priority order configurations and event-type mappings before crises occur. When an event is detected, the system automatically applies the pre-configured priority scheme, eliminating negotiation time. This is implemented through pre-defined event types (natural disaster, war, etc.) and corresponding priority order configurations stored in the system.
Solution Approach 2:
The patent implements dynamic priority order adjustment based on detected events. The system transitions from static fixed priority allocation to dynamic event-driven priority assignment, allowing automatic reconfiguration of spectrum access priorities in response to changing conditions without requiring manual intervention or lengthy negotiations.
2Reliability
If dedicated frequency bands are assigned to each network, then interference is minimized, but spectrum resource efficiency deteriorates
Solution Approach 1:
The system changes the priority order parameter dynamically based on event types. Different event types (natural disaster, war, demonstration) trigger different priority configurations, allowing the same frequency band to serve different networks with appropriate priorities depending on the situation, thus reducing spectrum waste while maintaining reliable communication when needed.
Solution Approach 2:
The patent enables frequency bands to serve multiple networks and multiple purposes through dynamic priority allocation. Instead of dedicating bands to single networks, the system allows any network to access any band with appropriate priority based on the event, making the spectrum infrastructure universal and adaptable to various crisis scenarios.
3Adaptability or versatility
If manual negotiation and agreement processes are used for priority changes, then regulatory control is maintained, but response speed deteriorates
Solution Approach 1:
The system implements automatic event detection and self-triggered priority reconfiguration without requiring manual regulatory intervention. The system monitors for events, determines the event type, and automatically applies the corresponding priority order configuration, enabling rapid response while maintaining regulatory frameworks through pre-approved event types and configurations.
Solution Approach 2:
The system continuously monitors for events and uses this feedback to automatically adjust priority orders. When an event is detected, the system receives feedback about the event type and automatically reconfigures priorities accordingly, creating a closed-loop system that responds rapidly to changing conditions without manual intervention.
