Solution Overview

Problem

In vehicular communication systems, existing technologies face challenges in managing Quality of Service (QoS) resources effectively, particularly in scenarios where multiple vehicles rely on the same base station, leading to insufficient wireless resources for safety-critical services like tele-operated driving and platooning, which require timely and dependable data transmission.

Innovation Solution

A method where vehicles request QoS options from a base station, which determines and provides suitable QoS options that balance resource utilization across multiple vehicles, associating these options with priority values to ensure timely and dependable data transmission while avoiding resource congestion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the base station provides all vehicles with a fair share of wireless resources, then resource distribution fairness is improved, but the timely and dependable data transmission for safety-critical services deteriorates

Engineering Contradiction:
Improveresource distribution fairnessVSAvoidtimely and dependable data transmission
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies local quality by differentiating resource allocation based on service type. Safety-critical services receive prioritized resource allocation with guaranteed QoS parameters (latency, jitter, packet loss), while non-critical services receive best-effort service. This ensures that critical services maintain reliable timely transmission while other services still receive fair resource distribution.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements dynamic QoS parameter adjustment based on current network conditions and service requirements. The base station dynamically modifies resource allocation, priority levels, and transmission parameters in response to changing traffic patterns and availability, allowing the system to adapt between fairness and reliability requirements in real-time.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the base station provides multiple QoS options to vehicles, then service adaptability is improved, but the complexity of resource management deteriorates

Engineering Contradiction:
Improveservice adaptabilityVSAvoidresource management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments QoS options into distinct service categories (e.g., safety-critical services, non-critical services) with predefined QoS parameter sets. This segmentation simplifies resource management by organizing multiple QoS options into structured categories rather than handling them as individual complex configurations, while still providing vehicles with adaptable service choices.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent manages QoS options by adjusting key parameters (priority level, resource allocation ratio, latency tolerance) rather than creating entirely different service architectures. This parameter-based approach allows multiple QoS levels to be achieved through modifications of existing resource management mechanisms, reducing overall system complexity.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If vehicles select QoS options with high priority values, then data transmission reliability is improved, but the wireless resource utilization efficiency deteriorates

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidwireless resource utilization efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies partial action by providing vehicles with a limited set of QoS options rather than allowing unlimited priority selections. The base station offers a manageable number of QoS levels (e.g., 1-5 priority levels) that provide sufficient reliability for most services without enabling excessive priority claims that would waste wireless resources. This balances reliability needs with resource utilization efficiency.

Inventive Principle:
Principle #16Partial or excessive action
