Solution Overview

Problem

Current wireless communication systems face inefficiencies in managing spectrum access, leading to high costs and unreliable network access due to segmented spectrum allocation and underutilization of licensed spectrum by certain users, such as public safety agencies and commercial network providers.

Innovation Solution

A system and method that prioritize spectrum access by grouping radio devices into classes, assigning weights and thresholds to each class, and aggregating these to determine access rights, ensuring higher priority users maintain service quality while allowing lower priority users to access shared spectrum without licenses, using a spectrum access management system that tracks and manages channel usage dynamically.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If spectrum is segmented into artificial categories and licensed to specific providers, then reliability of spectrum access is improved for licensed users, but cost increases and spectrum utilization efficiency deteriorates

Engineering Contradiction:
Improvespectrum access reliabilityVSAvoidspectrum utilization efficiency
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent segments spectrum access rights into different priority classes (first class with higher priority, second class with lower priority) rather than creating artificial licensing barriers. This allows the same spectrum to be shared among multiple users while maintaining reliability for high-priority users and improving overall utilization by allowing lower-priority users to access unused capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spectrum resource is designed to serve multiple functions and user classes simultaneously. The same spectrum channel can be used by first class users requiring high reliability and second class users seeking cost-effective access, with the system dynamically allocating access based on current conditions and priority levels.

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

2Reliability

If spectrum is licensed exclusively to one provider, then service quality for that provider is improved, but spectrum capacity utilization deteriorates when the provider has excess capacity

Engineering Contradiction:
Improveservice qualityVSAvoidspectrum capacity utilization
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system dynamically adjusts spectrum access based on real-time conditions. When first class users have excess capacity, second class users can access the spectrum. The weight aggregation mechanism and threshold comparisons enable dynamic allocation that responds to changing utilization patterns, ensuring both service quality for licensed users and improved overall capacity utilization.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spectrum sharing mechanism allows the system to self-regulate allocation without constant external control. The weight aggregation automatically reflects current usage patterns, and the threshold comparison mechanism autonomously determines when to grant or deny access to second class users based on whether first class users are utilizing their allocated capacity.

Inventive Principle:
Principle #25Self-service

3Reliability

If weights are assigned to radio devices based on class priority, then access control for high-priority users is improved, but system complexity increases

Engineering Contradiction:
Improvepriority-based access controlVSAvoidspectrum management system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system segments radio devices into discrete priority classes (first class and second class) with assigned weights, rather than implementing continuous or fine-grained priority differentiation. This segmentation simplifies the management complexity while still providing effective priority-based access control through the weight aggregation mechanism.

Inventive Principle:
Principle #1Segmentation

AI summary

A method and system for controlling access to a spectrum resource by radio devices that are grouped into a first class and a second class, the first class having higher priority to the spectrum resource than the second class. The control techniques include setting a weight for each radio device in each class of radio devices; setting a threshold for each class of radio devices; aggregating the weights of radio devices that use the spectrum resource; and determining if the aggregate weight crosses the threshold for one of the classes of radio devices and, if so, denying access to the spectrum resource for additional radio devices belonging to the class of radio devices associated with the crossed threshold.
