Transmission-Receipt Correlation for Mobile Network Quality Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to accurately determine the correspondence between data observed on the receiving side and the transmission event while a device is moving, particularly in the context of network quality measurement for automated vehicles, as stopping to measure is impractical.
Innovation Solution
A system that records time/location information, transmission identifiers, and observation data to determine the correspondence between transmission times and locations with received data, using a transmission-reception-correspondence determination unit to associate identifiers and locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the device stops on the public road to measure network quality, then the measurement precision is improved, but the device cannot continue moving and occupies the public road
Solution Approach 1:
The patent applies preliminary action by recording time and location information at the transmission side before the actual measurement occurs. The transmission device records timestamps and location data associated with transmitted data packets, enabling the receiving device to later correlate received data with the corresponding transmission events without requiring the device to stop moving. This preliminary recording of contextual information allows accurate network quality measurement to be performed while the device continues its movement.
2Productivity
If the device moves on the public road to measure network quality, then the productivity is improved, but the correspondence between transmission events and observed data cannot be strictly determined
Solution Approach 1:
The patent introduces time and location information as intermediary elements that bridge the transmission side and reception side. The transmission device records time stamps and location data associated with transmitted data, which are then transmitted along with the data packets. The receiving device uses these intermediary time and location records to correlate received data with the corresponding transmission events, enabling accurate correspondence determination while maintaining continuous movement during measurement.
3Productivity
If video is transmitted continuously for real-time information, then the productivity is improved, but the transmission and reception cost increases
Solution Approach 1:
The patent applies feedback by measuring network quality indicators (such as packet loss rate, transmission delay, and jitter) during continuous video transmission and using this feedback information to evaluate and optimize the transmission process. The received data includes network quality measurements that can be fed back to the transmission device to adjust transmission parameters, enabling continuous real-time information transmission while monitoring and managing transmission costs through feedback-driven optimization.

AI summary
A transmission-reception-correspondence determination system includes: a processor, and a memory storing program instructions that cause the processor to: record information indicating a relationship between a location of a moving device and time; record identifiers of pieces of information transmitted from the device in association with transmission times of the pieces of information; record an identifier of information transmitted from the device and data observed regarding the information in an apparatus that has received the information via a network in association with each other; and determine that a transmission time associated with an identifier that is same as the recorded identifier among the identifiers of the pieces of information and a location of the device at the transmission time correspond to the data associated with the recorded identifier.
