Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle-to-X (V2X) communication, the communication device onboard a mobile object faces challenges in synchronizing with varying synchronization signals of different accuracy and availability, such as those from LTE base stations, GPS satellites, and other mobile devices, leading to instability in synchronization processes.
Innovation Solution
The communication device is equipped with a selection mechanism that determines the most suitable synchronization signal based on its movement trajectory and availability, selecting between signals from LTE base stations, GPS satellites, and other mobile devices using map information and positioning data to ensure stable synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a communication device uses multiple types of synchronization signals (LTE base station, GPS satellite, other mobile devices) for synchronization, then the availability of synchronization signals is improved, but the stability of the synchronization process deteriorates due to varying accuracy and areas of use
Solution Approach 1:
The patent implements dynamic selection of synchronization signals based on the movement trajectory of the mobile object. The determination unit detects whether the mobile object is moving toward a location where at least one synchronization signal becomes unavailable, and the selection unit dynamically switches between different synchronization signals (GPS satellite, LTE base station, or other mobile devices) accordingly. This dynamic adaptation resolves the contradiction by maintaining stability through intelligent switching while preserving availability through multiple signal options.
2Reliability
If the communication device dynamically selects synchronization signals based on movement trajectory, then the stability of synchronization is improved, but the device complexity increases due to additional positioning and determination functions
Solution Approach 1:
The patent leverages existing multi-functional components to avoid adding significant complexity. The positioning function utilizes standard GPS reception capabilities already present in mobile devices. The determination unit repurposes trajectory analysis functionality for synchronization signal selection. The selection unit integrates with existing synchronization mechanisms. By making existing components serve multiple functions, the patent achieves stable dynamic selection without proportionally increasing device complexity.

AI summary
An electronic device that is configured to receive synchronization signals transmitted from each of a plurality of devices, select at least one synchronization signal from among the synchronization signals to perform a synchronization process based on a determination that the electronic device is moving toward a location at which at least one of the synchronization signals is not available, and perform the synchronization process based on the selected synchronization signal
