UE Connection Data Ledger for Immutable Incident Records
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communications networks lack the ability to capture and store connection data with integrity, making it difficult to establish an immutable record of network conditions during incidents involving autonomous machines, which can lead to disputes over liability.
Innovation Solution
Implementing a system with a network operator core that collects UE monitoring session blocks using distributed ledger technology to create an immutable witness data archive, capturing connection data between user equipment and the network core, ensuring data integrity and preventing manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional data storage methods are used for wireless connection data, then storage and retrieval are simple and cost-effective, but data integrity cannot be guaranteed and manipulation cannot be prevented
Solution Approach 1:
The patent introduces a distributed ledger as an intermediary layer between the wireless network and traditional storage systems. The ledger captures connection data in immutable blocks with cryptographic hashing, serving as a trusted mediator that prevents data manipulation while maintaining compatibility with existing network infrastructure. This resolves the contradiction by providing data integrity guarantees without requiring complete system redesign.
Solution Approach 2:
The patent segments connection data into discrete blocks that are individually hashed and linked in a chain structure. Each block contains specific connection events and references to previous blocks, creating modular units of immutable data. This segmentation approach enables verified data integrity while maintaining manageable system complexity through structured data organization.
2Reliability
If connection data is captured and stored for incident investigation, then accountability can be established, but data storage costs and processing overhead increase
Solution Approach 1:
The patent extracts only the essential connection data elements needed for accountability into the immutable ledger, such as connection timestamps, participant identifiers, and critical event markers. Non-essential detailed data remains in traditional storage systems. This selective extraction provides sufficient accountability information while minimizing the volume of data requiring expensive immutable storage.
Solution Approach 2:
The patent uses a hierarchical storage approach where frequently accessed verification data resides in the immutable ledger and less critical detailed data can be stored in cheaper, more easily replaceable traditional storage systems. This allows the system to maintain accountability through the immutable portion while using cost-effective storage for the remainder.
