Logging Duration Timer for Wireless Network Data Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular network performance logging systems face challenges in determining when to stop logging network performance information, leading to unnecessary battery drain and strain on mobile devices, as existing standards require continuous logging during idle mode without a clear mechanism to set a time limit.
Innovation Solution
Implementing a logging duration timer that allows mobile devices to log network performance information for a specified duration, even in idle mode, by configuring the timer when the device transitions to idle mode and stopping it when the duration expires, thus balancing data collection with power conservation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mobile devices continuously log network performance information during idle mode, then network data collection is improved, but battery consumption increases
Solution Approach 1:
The patent implements periodic logging of network performance information during idle mode, where the device logs data at specified time intervals rather than continuously. The system uses a logging duration timer that periodically triggers logging operations, allowing the device to collect necessary network data while remaining in low-power idle mode for extended periods between logging events.
Solution Approach 2:
The patent dynamically adjusts the logging behavior based on the duration of idle mode. When the idle mode duration exceeds a threshold, the device activates logging with a specified duration timer. The system adapts its logging strategy based on real-time conditions, including whether the device is in connected or idle mode, and adjusts the logging duration accordingly to balance data collection needs with power conservation.
2Reliability
If mobile devices log network performance information for extended periods, then network coverage evaluation is improved, but device complexity increases
Solution Approach 1:
The patent configures the logging duration timer in advance before the actual logging process begins. The network provides logging configuration parameters including the logging duration, and the device pre-configures the timer with these parameters while still in connected mode. This preliminary configuration simplifies the subsequent logging process by having all parameters predetermined, reducing the need for complex real-time decision-making mechanisms.
Solution Approach 2:
The patent introduces a logging duration timer as an intermediary mechanism that mediates between the logging process and the device's power management system. The timer acts as a simple, dedicated component that automatically controls the logging duration without requiring complex processing logic, thereby improving network coverage evaluation while minimizing the increase in device complexity.
3Duration of action of moving object
If mobile devices stop logging during idle mode, then battery life is extended, but network performance data quality deteriorates
Solution Approach 1:
The patent implements periodic logging during idle mode, where the device logs network performance information at specified intervals rather than continuously or not at all. The logging duration timer ensures that logging occurs for a sufficient duration to capture meaningful network performance data, including information about network coverage and signal quality during the idle period, while still allowing the device to conserve battery by remaining in idle mode between logging events.

AI summary
A method and system controls timing of network performance information logging of a cellular network by configuring a mobile device to automatically collect data about physical characteristics of the cellular network and log that data. The mobile device initially receives network performance information logging configuration from its registered cellular network. Based on the configuration, the mobile device configures itself to collect and log the network performance information relating to physical characteristics of the cellular network. While in idle mode, the mobile device collects and logs the information. A logging duration timer corresponds to a specified time duration over which the mobile device logs network performance information. If the mobile device starts the logging duration timer at the time of configuration, it maintains the timer even after the transition to idle mode. The mobile device may also start the logging duration timer after it transitions to idle mode.
