Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remotely manipulated vehicles, unmanned aerial vehicles, and robots face challenges in promptly adjusting their target tasks and work modes based on current or predicted network status, leading to issues such as long switching times and high probabilities of process failures.
Innovation Solution
An electronic apparatus with processing circuitry determines target tasks and triggers PDU session requests to manage QoS flows, allowing for efficient task switching and resource allocation based on network conditions, including backup tasks to ensure continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional task switching methods are used in remotely manipulated vehicles, then the system can maintain simple operation, but the task switching time becomes long and process failure probability increases
Solution Approach 1:
The patent establishes PDU session templates in advance that define QoS flow configurations for different task types. When task switching is needed, the system activates a pre-configured template instead of creating QoS flows from scratch, dramatically reducing switching time and failure probability. The template includes all necessary QoS parameters, PDU session configurations, and resource allocation rules ready for immediate deployment.
Solution Approach 2:
The system dynamically adjusts QoS flow parameters based on the active task type by selecting appropriate PDU session templates. Each template contains optimized QoS parameters (bandwidth, latency, packet loss tolerance) specific to particular task requirements. This parameter-based approach allows rapid task switching without reconfiguring the entire communication stack, resolving the contradiction between switching speed and reliability.
2Adaptability or versatility
If the system configures QoS flows dynamically during task switching, then it can adapt to different task requirements, but the configuration time increases and process complexity rises
Solution Approach 1:
PDU session templates are pre-configured with all necessary QoS flow parameters, PDU session settings, and resource allocation rules for various task types. This preliminary configuration stores multiple task-specific profiles that can be instantly activated, eliminating the need for time-consuming dynamic QoS configuration while maintaining full adaptability to different task requirements.
Solution Approach 2:
The system uses template copying where a complete QoS configuration template for a source task is copied and activated for the target task. This copying mechanism preserves all the detailed QoS settings and parameters of the original task configuration, enabling rapid task switching with full adaptability without manual reconfiguration or complex real-time calculations.
3Reliability
If the system establishes new PDU sessions for each task, then it can ensure dedicated resources, but the session establishment time becomes long
Solution Approach 1:
Multiple QoS flow configurations for different task types are merged into a single PDU session template structure. The template contains hierarchical configurations that allow one PDU session to support multiple task types by activating different QoS flow subsets. This merging eliminates the need to establish entirely new PDU sessions for each task, reducing establishment time while maintaining dedicated resource allocation through selective QoS flow activation.
Solution Approach 2:
The system pre-establishes PDU session templates with all necessary resource allocations and QoS configurations before tasks begin. These templates include pre-allocated bandwidth, buffer sizes, and priority settings that are immediately applicable when a task starts. This preliminary resource preparation ensures dedicated resources are available without the delay of runtime session establishment.
