Solution Overview

Problem

Existing spectrum allocation systems are not scalable to meet the needs of 5G networks and fail to provide flexible, decentralized access to spectrum resources for businesses and enterprises, particularly for short-term or geographically confined applications, often favoring large operators and creating artificial value chains.

Innovation Solution

A decentralized spectrum marketplace using a permissioned distributed ledger (blockchain) for spectrum licensing and policy management, enabling flexible spectrum allocation through smart contracts between owners and renters, with automated authorization and payment mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If centralized databases are used to maintain spectrum allocation records, then spectrum management can be implemented, but the system lacks scalability and flexibility for 5G networks and decentralized access

Engineering Contradiction:
Improveflexibility of spectrum allocationVSAvoidcentralized database structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the centralized spectrum management system into distributed ledger nodes across multiple entities (spectrum owners, renters, regulators). Each node maintains a copy of the spectrum allocation records, eliminating the single-point bottleneck of centralized databases and enabling scalable decentralized access for 5G networks.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimensional approach by implementing spectrum allocation across spatial dimensions (geographical areas) and temporal dimensions (specific durations) through smart contracts. This multi-dimensional allocation framework enables flexible leasing arrangements that adapt to diverse 5G use cases while maintaining regulatory compliance.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If traditional licensing regimes are used, then spectrum allocation can be controlled, but administrative barriers and complexity increase for businesses and enterprises

Engineering Contradiction:
Improveease of spectrum accessVSAvoidadministrative overhead
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent enables self-service spectrum access through automated smart contracts that allow businesses to directly lease spectrum resources without extensive manual administrative processing. The smart contracts automatically handle allocation, tracking, and compliance verification, reducing bureaucratic overhead while maintaining regulatory control through programmable enforcement rules.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual administrative mechanisms with automated computational mechanisms. Smart contracts use cryptographic verification and automated enforcement to substitute human-mediated licensing processes, eliminating paper-based procedures and reducing administrative complexity for spectrum access while maintaining regulatory oversight.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If spectrum is allocated through regulatory fiat, then allocation can be implemented, but efficiency and responsiveness to demand decrease

Engineering Contradiction:
Improvespectrum utilization efficiencyVSAvoidresponse time to demand changes
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent implements dynamic spectrum allocation through smart contracts that can be modified and adapted in real-time based on demand conditions. Unlike static regulatory allocations, the smart contract framework allows spectrum rights to be dynamically leased, transferred, and reallocated across different time periods and geographical areas, maximizing utilization efficiency while rapidly responding to emerging 5G use cases.

Inventive Principle:
Principle #15Dynamics

AI summary

A method and a spectrum owner system are described. The spectrum owner system records, in a distributed ledger network, a list of spectrum resources licensed from a regulatory authority system to the spectrum owner system. The spectrum owner system receives an authorization request for a spectrum allocation of spectrum resources, where the spectrum 5 allocation includes at least a desired interval of time for usage of the spectrum resources by a radio access network of a spectrum renter, a desired location for usage of the spectrum resources by the radio access network, and additional characteristics of the spectrum resources. The spectrum owner system negotiates agreement terms for the desired spectrum allocation; and records, in the distributed ledger network, a hash of the spectrum allocation, where the spectrum 0 allocation enables the radio access network of the spectrum renter to provide radio access services to wireless network devices.
