Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network infrastructure lacks secure and reliable methods for validating the location of user equipment (UE) and monitoring the health metrics of base stations, which can lead to connectivity issues and security vulnerabilities.
Innovation Solution
The use of blockchain technology to securely record and verify information from base stations, including location data and health metrics, ensures that only authenticated sources can contribute to the determination of UE location and base station health, thereby enhancing security and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wireless network validation methods are used, then the system is simpler to operate, but security and reliability are compromised
Solution Approach 1:
The patent introduces blockchain technology as an intermediary layer between wireless devices and the validation system. The blockchain ledger serves as a neutral, decentralized mediator that records and validates device identities, locations, and health metrics without requiring direct trust between network participants. This intermediary mechanism enhances validation reliability while maintaining operational simplicity through automated smart contract execution.
Solution Approach 2:
The patent replaces traditional centralized validation mechanisms with a decentralized blockchain-based system. Instead of relying on centralized authorities or manual validation processes, the system uses cryptographic protocols, distributed consensus algorithms, and smart contracts to automatically validate device information. This substitution eliminates single points of failure and enhances reliability without significantly increasing operational complexity.
2Reliability
If blockchain technology is implemented for secure recording, then security is improved, but device complexity increases
Solution Approach 1:
The patent implements a distributed ledger where multiple nodes maintain identical copies of the blockchain data. Each participant in the wireless network holds a copy of the validated device information, health metrics, and location data on their local blockchain node. This copying mechanism ensures security through redundancy and consistency across the network, while the standardized data structures keep the implementation manageable despite the distributed architecture.
3Measurement precision
If multiple base station signals are used for triangulation, then location determination accuracy is improved, but the risk of security breaches increases
Solution Approach 1:
The patent performs preliminary validation of base station identities and signal authenticity before using them for triangulation calculations. Smart contracts verify the digital signatures and credentials of base stations beforehand, ensuring that only authenticated sources contribute to location determination. This preliminary security check prevents malicious or compromised base stations from corrupting the triangulation process, thereby maintaining both accuracy and security.
Solution Approach 2:
The patent implements a feedback mechanism where the blockchain system continuously monitors and validates the integrity of base station signals used in triangulation. The distributed ledger records verification results, and this information feeds back into the validation process for subsequent location determinations. This ongoing feedback loop ensures that only signals from verified, secure base stations are used, maintaining high accuracy while mitigating security risks.
Data Source
AI summary
A system described herein may identify a particular value that was wirelessly received by a User Equipment (“UE”) at a first time. The particular value may have been recorded to a blockchain, along with a second time, at which the particular value was outputted by a base station of a wireless network. The particular value may include a randomly generated number. The system may determine a location of the base station from which the particular value was outputted. The location of the UE may be determined based on a delay time associated with the particular value, which may be determined based on a difference between the first and second times. The location of the UE may further be determined (e.g., using triangulation techniques) based on values outputted by other base stations, for which the blockchain includes records indicating times at which such values were outputted by the other base stations.
