Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote driving technologies lack a comprehensive solution for switching between remote driving modes, such as human remote control (HRC) and machine remote control (MRC), which hinders adaptability to complex road and network conditions.
Innovation Solution
A method and apparatus that obtain and manage protocol data unit (PDU) session parameter information for multiple remote control modes, allowing for seamless switching between HRC and MRC modes based on mode switching information, enabling the vehicle to adapt to changing conditions by switching between different PDU session parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote driving mode switching is not implemented, then the system structure remains simple, but the adaptability to complex road and network conditions deteriorates
Solution Approach 1:
The patent implements dynamic mode switching between HRC and MRC remote driving modes based on real-time network conditions and road situations. The system dynamically adjusts the remote control mode through mode switching information transmitted between the terminal device and network elements, allowing the system to adapt to changing conditions without requiring multiple fixed systems.
Solution Approach 2:
The patent creates a universal remote driving control system that can operate in multiple modes (HRC and MRC) using a single integrated architecture. The session management function entity and application function entity work together to provide multi-functional capabilities through a unified system that handles both human-remote-control and machine-remote-control modes.
2Adaptability or versatility
If multiple PDU session parameters are managed for different modes, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The patent introduces a session management function entity as an intermediary that handles the complex task of managing multiple PDU session parameters. This intermediary receives mode switching information, determines the appropriate session parameters for HRC or MRC modes, and coordinates with the application function entity, thereby simplifying the overall system architecture while enabling multi-mode operation.
Solution Approach 2:
The system implements feedback mechanisms where mode switching information is transmitted from the terminal device to the network elements, and session parameter information is fed back to ensure proper mode configuration. This feedback loop allows the system to automatically adjust parameters based on the selected mode without requiring manual intervention.

AI summary
In a method for remotely controlling a vehicle, protocol data unit (PDU) session parameter information corresponding to a plurality of remote control modes of the vehicle is obtained by a session management function entity. The plurality of remote control modes includes a first remote control mode and a second remote control mode. While the vehicle is controlled according to the PDU session parameter information corresponding to the first remote control mode, mode switching information is received from an application function entity by the session management function entity. The mode switching information indicates the first remote control mode is to be switched to the second remote control mode. Based on the mode switching information, the vehicle is controlled by the session management function entity to switch to remote control according to the PDU session parameter information corresponding to the second remote control mode.
