Server Error Correction via Activity Log Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems, particularly those involving battery-powered mobile devices, face inefficiencies in error correction during radio transmissions, leading to wasted transmission time and battery power due to uncorrected errors that are not addressed effectively by traditional server protocols.
Innovation Solution
Implementing an error correction system where the server monitors transmissions for error signals, increments an error counter, and upon reaching a threshold, requests the mobile device to send a recent-activity-log for analysis and correction, allowing the server to diagnose and correct errors that cannot be resolved at the device level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the server repeatedly instructs the station to re-send data packets or carries out corrective routines, then error correction attempts are made, but the communication system becomes bogged down with delays and poor performance
Solution Approach 1:
The server performs preliminary analysis of error patterns by monitoring and counting specific error types before initiating correction procedures. The error counter tracks recurring errors, allowing the server to identify systematic problems in advance and implement targeted corrections rather than repeated generic re-send instructions, thereby reducing transmission delays while maintaining reliability
Solution Approach 2:
The system implements feedback through the error counter mechanism that continuously monitors transmission errors and provides information about error frequency and patterns to the server. This feedback loop enables the server to adapt its correction strategy based on actual error patterns, avoiding unnecessary repeated re-send instructions and reducing communication overhead
2Device complexity
If traditional server protocols are used for error detection, then simple re-send instructions are issued, but transmission time and battery power are wasted due to uncorrected errors
Solution Approach 1:
The mobile station performs self-diagnosis by detecting and reporting specific error types to the server through the error counter mechanism. This self-service capability allows the station to identify problems that require server intervention, enabling more efficient error handling that reduces unnecessary re-transmissions and conserves battery power while maintaining protocol simplicity
3Measurement precision
If the server monitors and counts error events, then systematic errors can be identified, but the server requires more processing resources and information management
Solution Approach 1:
The error monitoring function is segmented between the mobile station and the server. The mobile station's error counter handles local error detection and classification, segmenting the complex task of error analysis from the server. This segmentation allows the server to receive pre-processed error information, reducing its processing burden while maintaining high measurement precision through the combined monitoring system

AI summary
Errors of e.g database synchrony between a radio-connected mobile-station and a server can be especially troublesome if continued and repeated, and can quickly deplete resources in the mobile-station. This problem is addressed by keeping an error-event-count in the server; when the count exceeds a threshold, the server signals the mobile to immediately transmit the recent-activity-log in the mobile, i.e the log in the mobile in which are recorded the detailed elements relating to assembling and transmitting the data packet in which the error was detected. Using the information in the recent-activity-log, the server can institute de-bugging strategies, etc, to correct the problem. The threshold is in two stages; above the initial threshold, the mobile-station is signalled to increase the level of detail as recorded in the recent-activity-logs (if the mobile is able to do so), and the actual transmission of the log only takes place above the main threshold.
