Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing log data collection systems face network congestion issues due to excessive communication traffic, particularly when transmitting log data through wireless networks like W-CDMA and LTE, which can lead to delayed data collection and network load imbalances.
Innovation Solution
A log data collection system that includes a terminal device with a transmission determination unit, which determines the optimal timing for transmitting log data based on the device's state, network state, and remaining transmission period, ensuring data is sent within a permissible time frame to manage network load effectively.

Engineering Contradiction Analysis
1Productivity
If log data is transmitted periodically through wireless network, then log data collection frequency is improved, but network congestion occurs due to excessive communication traffic
Solution Approach 1:
The system implements periodic log data transmission with dynamically adjusted intervals. The transmission interval is extended when network congestion is detected or terminal device load is high, and shortened when network conditions are good, achieving periodic action that adapts to system state rather than fixed periodicity
Solution Approach 2:
The log data transmission system transitions from static periodic transmission to dynamic adaptive transmission. The transmission timing is adjusted in real-time based on network congestion levels and terminal device load states, making the system flexible and responsive to changing conditions
2Loss of information
If log data transmission is performed at high frequency, then data collection completeness is improved, but terminal device load increases
Solution Approach 1:
The system dynamically adjusts transmission frequency based on terminal device load state. When device load is high, transmission interval is extended to reduce energy consumption; when device load is low, transmission frequency increases to improve data completeness, creating a dynamic balance between these competing requirements
3Reliability
If network load monitoring is implemented to avoid congestion, then network stability is improved, but system complexity increases
Solution Approach 1:
The system implements feedback mechanisms where transmission decisions are based on monitored network congestion levels and terminal device load states. The system continuously monitors system state and adjusts transmission timing accordingly, creating a closed-loop control system that maintains network stability through adaptive feedback
Solution Approach 2:
The transmission control system operates autonomously by monitoring its own state and making self-adjustments. The terminal device itself monitors network conditions and device load, then automatically adjusts transmission timing without requiring complex external control infrastructure

AI summary
A log data collection system includes a terminal device accumulating log data; and a collection device collecting the log data from the terminal device through a network, wherein the terminal device includes transmission determination unit which determines a timing of transmitting the log data to the collection device, within a permissible transmission period, being a time span in which transmission of the log data is permitted, based on a state of the terminal device, a state of the network, and a remaining time of the permissible transmission period.
