Server Device Optimizing V2X Uplink Transmission Cost
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In V2X communication, there is a need to reduce the cost of transmitting uplink data from terminals, as existing methods do not effectively minimize communication costs, especially during peak traffic times when operational expenditures increase.
Innovation Solution
A server apparatus determines the most cost-effective terminal and time for transmitting uplink data by analyzing communication costs and terminal locations within a communication area, instructing the selected terminal to transmit data when costs are lowest, thereby reducing overall communication expenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminals transmit uplink data during peak traffic times, then communication service is maintained, but communication cost increases significantly
Solution Approach 1:
The server determines in advance which terminals should transmit uplink data during low-cost periods and stores this determination result. When the terminal later transmits data, it references this pre-determined information to automatically select cost-effective transmission timing, thereby reducing communication costs while maintaining service reliability.
Solution Approach 2:
The terminal uses the pre-determined transmission timing information provided by the server to autonomously decide when to transmit uplink data. This self-service mechanism allows terminals to independently optimize their transmission timing based on cost considerations without requiring real-time server intervention, thus reducing overall communication costs.
2Speed
If terminals transmit uplink data immediately when needed, then communication speed is maintained, but communication cost increases
Solution Approach 1:
The server performs preliminary determination of cost-effective transmission timing and communicates this information to terminals in advance. Terminals can then plan their data transmissions to coincide with low-cost periods identified by the server, achieving cost reduction without significantly impacting transmission speed requirements.
Solution Approach 2:
The system dynamically adjusts transmission timing based on varying communication costs at different times and locations. The server's determination result reflects dynamic cost conditions, allowing terminals to adapt their transmission schedules flexibly to minimize costs while meeting service requirements.
3Productivity
If all terminals transmit uplink data simultaneously, then data collection efficiency is maintained, but communication cost increases
Solution Approach 1:
The server divides the communication area into different segments and determines transmission timing separately for each terminal based on its location and cost conditions. This segmentation allows terminals in different areas to transmit at different optimal times, reducing peak traffic costs while maintaining overall data collection efficiency.
Solution Approach 2:
The transmission timing determination is customized for each terminal based on its specific location and local cost conditions. Each terminal receives tailored transmission recommendations suited to its local environment, optimizing cost efficiency locally while collectively maintaining system-wide productivity.
