Teleoperated Driving Network Slice QoS Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications systems for teleoperated driving face challenges in maintaining consistent quality-of-service (QoS) due to fluctuations in wireless channel data rates, which can compromise vehicle safety by not adequately translating teleoperation configurations into appropriate QoS requirements, leading to potential safety hazards if provisioned QoS parameters are not met.
Innovation Solution
A network operator configured to create and monitor network slices for teleoperated vehicles, receiving QoS requests from teleoperation applications, and proactively notify them of changes in QoS parameters, predicting and adjusting QoS to ensure safe driving conditions by reconfiguring network slices in real-time.

Engineering Contradiction Analysis
1Measurement precision
If the TOApplication uses high data rate video streams to improve video quality, then video quality is improved, but the reliability of teleoperated driving deteriorates due to wireless channel fluctuations
Solution Approach 1:
The patent implements dynamic adaptation of teleoperation configuration based on real-time QoS monitoring. The TOApplication continuously monitors QoS parameters and dynamically adjusts video stream configurations (resolution, bitrate, frame rate) to match current network conditions, ensuring both video quality and safety are maintained under varying channel conditions
Solution Approach 2:
The patent establishes a closed-loop feedback mechanism where the TOApplication monitors QoS parameters, compares them against required thresholds, and triggers reconfiguration of teleoperation settings when QoS degradation is detected. This feedback loop ensures that video quality and safety requirements are continuously satisfied
2Reliability
If the network operator creates per-vehicle QoS requirements to improve safety, then vehicle safety is improved, but the complexity of network management increases
Solution Approach 1:
The patent creates a universal QoS mapping framework that translates diverse teleoperation configurations (different video resolutions, sensor types, haptic feedback settings) into standardized QoS parameters (bitrate, latency, jitter thresholds). This universal mapping mechanism simplifies network management by providing a consistent interface for handling various vehicle requirements
Solution Approach 2:
The patent transforms complex teleoperation configuration parameters into standardized QoS parameters that the network can uniformly manage. By changing the parameter representation from application-specific to network-standard parameters, the system simplifies network slicing and resource allocation while maintaining per-vehicle safety requirements
3Reliability
If the TOApplication monitors QoS parameters continuously to improve safety, then vehicle safety is improved, but the loss of time for processing and responding increases
Solution Approach 1:
The patent implements selective monitoring of QoS parameters based on their criticality to safety. Instead of continuously analyzing all QoS metrics, the system focuses on monitoring only the most critical parameters (latency for control commands, bitrate for video streams) at appropriate intervals, reducing processing overhead while maintaining safety
Solution Approach 2:
The patent pre-configures QoS thresholds and trigger conditions for different teleoperation scenarios before actual driving begins. By establishing prediction models and threshold settings in advance, the system can quickly respond to QoS violations without extensive real-time analysis, reducing response time while maintaining safety

AI summary
A network operator apparatus, a teleoperation application (TOApplication) apparatus, and an apparatus for a teleoperable vehicle are provided. The network operator apparatus creates a network slice for teleoperating the teleoperable vehicle along at least one route, receives a slice configuration request comprising QoS for the at least one route from the TOApplication apparatus, and configures the network slice to support the QoS. The TOApplication apparatus communicates towards the network operator apparatus, a request for creating the network slice, receives a teleoperation service request comprising a set of teleoperation configurations from the teleoperable vehicle, maps each teleoperation configuration to a respective QoS and sends the slice configuration request comprising the QoS to the network operator apparatus. The apparatus for the teleoperable vehicle sends the teleoperation service request to the TOApplication apparatus and controls the route to be followed by the teleoperable vehicle based on information from the TOApplication apparatus.
