Solution Overview

Problem

Existing wireless communication systems, particularly in 5G NR, face challenges in accurately classifying the reliability of data provided by wireless devices, leading to potential misinformation and disinformation that can impact safety and functionality in vehicle-to-vehicle communications.

Innovation Solution

Implementing a method and apparatus to classify wireless devices based on data accuracy, allowing for re-evaluation of device classifications and termination or modification of communication sessions to ensure accurate data usage, using sensor sharing and machine learning algorithms to identify and mitigate rogue actors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless devices share sensor data in V2V communications, then system functionality and safety maneuvers are improved, but the risk of misinformation and disinformation from rogue actors increases

Engineering Contradiction:

Improvesystem functionalityVSAvoiddata accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where receiving devices evaluate the accuracy of sensor data from transmitting devices by comparing it with locally available data. When inaccuracies are detected, the receiving device sends feedback to the network device to re-evaluate the classification of the transmitting device, enabling continuous improvement of data reliability while maintaining system functionality

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The network device acts as an intermediary that classifies wireless devices based on data accuracy and manages communication sessions. This intermediary layer filters and regulates V2V communications, allowing beneficial data sharing while blocking or terminating communications from rogue actors, thus resolving the contradiction between functionality and reliability

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If device classifications are made to manage data accuracy, then misinformation is reduced, but the complexity of the communication system increases

Engineering Contradiction:

Improvedata accuracyVSAvoidclassification system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the classification task into two parts: the network device performs initial classification of transmitting devices based on data accuracy, and receiving devices perform local evaluation by comparing received data with their own sensor data. This segmentation distributes the complexity across multiple entities, making the overall system more manageable while maintaining high data accuracy

Inventive Principle:

Principle #1Segmentation

3Reliability

If communication sessions are terminated for rogue actors, then data accuracy is maintained, but loss of information occurs when legitimate devices are misclassified

Engineering Contradiction:

Improvedata accuracyVSAvoidcommunication data loss

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The network device performs preliminary classification of wireless devices as accurate or inaccurate data sources before communication sessions begin. This preliminary action allows legitimate devices to be pre-authorized for data sharing while potential rogue actors are identified and blocked in advance, preventing both misinformation transmission and false rejection of valid data

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback loops where receiving devices can request re-evaluation of transmitting device classifications when data inaccuracies are detected. This feedback mechanism ensures that legitimate devices that may have been temporarily misclassified can restore their communication sessions, preventing permanent loss of valuable information while maintaining data accuracy standards

Inventive Principle:

Principle #23Feedback

AI summary

The apparatus may be a first wireless device configured to receive a first indication that a second wireless device associated with the first wireless device and a network device is classified as providing data of a first type. The apparatus may further be configured to receive a first set of data elements from the second wireless device. The apparatus may be configured to identify, based on the first set of data elements and a second set of data elements available at the first wireless device, that the classification of the second wireless device may be inaccurate and transmit, based on the identification that the classification of the second wireless device may be inaccurate, at least one of a second indication for the second wireless device to transmit a re-evaluation request or a third indication to the second wireless device to terminate a communication session with the first wireless device.
