Solution Overview
Problem
The increasing amount of data transmitted and received through road-vehicle wireless communication systems poses a challenge, as existing systems struggle to manage the growing data volume efficiently, leading to potential network overload and data handling issues.
Innovation Solution
A wireless communication device and system that determine communication amounts and transmit corresponding information to adjust data sizes, compress data when necessary, and prioritize data transmission based on available capacity and priority levels to prevent network overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the amount of data transmitted and received through road-vehicle wireless communication increases to support sophisticated services, then service functionality is improved, but network overload and data handling issues occur
Solution Approach 1:
The transmitting device performs preliminary determination of communication amount information before actual data transmission. This advance assessment allows the receiving device to prepare appropriate buffer sizes and data handling capacities, preventing network overload before it occurs while enabling sophisticated services to function properly
2Loss of information
If all data is transmitted without size adjustment, then data completeness is improved, but transmission efficiency deteriorates due to network overload
Solution Approach 1:
The system dynamically adjusts data transmission sizes based on real-time communication conditions and device capabilities. The transmitting device determines appropriate communication amount information and transmits data in optimized sizes, while the receiving device adapts its buffer allocation accordingly, ensuring both data completeness and transmission efficiency are maintained under varying network conditions
Solution Approach 2:
The system changes the parameter of data size based on communication amount information. By varying transmission packet sizes according to network conditions and device capabilities, the system optimizes transmission efficiency while preventing network overload, rather than using fixed-size transmissions

AI summary
A wireless communication includes a wireless communication unit that performs wireless communication with a vehicle and a processing unit that performs processing for communication, in which the processing unit determines a communication amount in wireless communication performed with one or a plurality of by the wireless communication unit, transmits communication amount information relating to the determined communication amount to the vehicle by the wireless communication unit, and receives data transmitted from the vehicle at a size corresponding to the communication amount by the wireless communication unit. The processing unit may receive the communication amount information relating to the communication amount in the in-vehicle network provided inside the vehicle from the vehicle, adjust the size of data to be transmitted to the vehicle according to the received communication amount information, and transmit the data with the adjusted size to the vehicle by the wireless communication unit.
