Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the Internet of Vehicles (IoV) system, determining an appropriate transmission mechanism for data transmission is challenging due to the variety of service requirements and communication paths, leading to suboptimal data transmission performance.
Innovation Solution
A method where a terminal device determines a suitable transmission mechanism based on service information, such as service type, IP address, and protocol version, using pre-configured mapping relationships to select the most appropriate digital modulation, rate matching, or duplicate transmission mechanisms for improved data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple transmission mechanisms are adopted for different service requirements, then data transmission performance is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring mapping relationships between service information and transmission mechanisms in the terminal device. When data needs to be transmitted, the device directly queries the pre-stored mapping table to determine the appropriate transmission mechanism, eliminating the need for real-time complex decision-making. This resolves the contradiction by preparing transmission mechanism selections in advance, improving reliability while keeping the actual transmission process simple.
Solution Approach 2:
The patent introduces an intermediary element - the mapping relationship table - that mediates between service information and transmission mechanisms. Instead of directly complexly analyzing service requirements and selecting mechanisms in real-time, the system uses the pre-established mapping table as an intermediary to quickly determine the appropriate transmission mechanism. This intermediary structure simplifies the selection process while ensuring optimal transmission performance.
2Device complexity
If transmission mechanism is determined without considering service information, then device complexity is reduced, but data transmission performance deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-configuring mapping relationships between service information and transmission mechanisms in the terminal device. When data needs to be transmitted, the device directly queries the pre-stored mapping table to determine the appropriate transmission mechanism, eliminating the need for real-time complex decision-making. This resolves the contradiction by preparing transmission mechanism selections in advance, improving reliability while keeping the actual transmission process simple.
Solution Approach 2:
The terminal device performs self-service by autonomously determining the appropriate transmission mechanism based on service information and pre-configured mapping relationships, without requiring external network device intervention. The device queries its own stored mapping table and selects the transmission mechanism independently, reducing complexity while maintaining optimal transmission performance through service-aware selection.
3Reliability
If service information is acquired and processed at protocol layers, then data transmission performance is improved, but loss of time increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring mapping relationships between service information and transmission mechanisms in the terminal device. When data needs to be transmitted, the device directly queries the pre-stored mapping table to determine the appropriate transmission mechanism, eliminating the need for real-time complex decision-making. This resolves the contradiction by preparing transmission mechanism selections in advance, improving reliability while keeping the actual transmission process simple.
