Cloudside Device Managing Roadside Devices via Differential Packet Policies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional intelligent transportation systems (ITS) face inefficiencies in resource utilization and network conflicts due to inadequate differential control of data packets on different roadside devices, which can impact emergency message delivery and overall traffic management.
Innovation Solution
A method and apparatus where a cloudside device acquires data packets from roadside devices, including state and dynamic traffic information, to adjust packet transmission policies for data links, enabling personalized control and optimizing resource utilization across various communication channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uniform packet transmission policy is applied to all roadside devices, then system simplicity is maintained, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements differential packet transmission policies tailored to specific roadside device types and traffic conditions. Different packet types (emergency, traffic information, control) receive customized transmission treatments including priority levels, modulation schemes, and resource allocation based on local requirements rather than uniform treatment across all devices.
2Productivity
If differential control of data packets is implemented for different roadside devices, then resource utilization efficiency is improved, but system complexity increases
Solution Approach 1:
The system dynamically adjusts transmission parameters such as packet priority, modulation and coding schemes, time-frequency resource allocation, and power levels based on device type, traffic condition, and packet urgency. This allows efficient differential control while maintaining manageable system complexity through parameter optimization rather than structural complexity.
3Reliability
If packet transmission policy is adjusted based on real-time data, then communication reliability is improved, but processing overhead increases
Solution Approach 1:
The system pre-establishes packet transmission policies for different device types and traffic conditions during system initialization or planning phases. These pre-configured policies are stored and automatically applied when specific conditions are detected, reducing real-time processing overhead while maintaining high communication reliability through condition-based policy selection.

AI summary
Embodiments of the present disclosure provide a method and apparatus for managing a roadside device in vehicle road cooperation, a cloud control platform and a system. The method includes: acquiring, by a cloudside device, a data packet from a roadside device, the data packet including at least one of state information of the roadside device and dynamic traffic information associated with the roadside device; and adjusting a packet transmission policy for a data link associated with the roadside device based on the data packet, the data link comprising at least one of a first downlink from the roadside device to a vehicle, a first uplink from the vehicle to the roadside device, a second uplink from the roadside device to the cloudside device, and a second downlink from the cloudside device to the roadside device, so that personalized management for roadside devices is achieved.
