Mobile Phone Debug Logging via SMS Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for validating mobile phone protocol stacks and modem hardware face challenges in diagnosing test failures during interoperability testing, as they require expert intervention and alignment of proprietary logging data from mobile phones and network equipment, often lacking live network logging information.
Innovation Solution
A system that enables direct transmission of debugging information from mobile phones to network testing equipment using SMS messages, allowing for simultaneous logging and analysis of data from both sides, facilitating automated diagnosis and potential corrections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If proprietary logging data from mobile phones and network equipment are used for diagnosing test failures, then diagnosis information can be obtained, but expert intervention and data alignment are required increasing complexity and time consumption
Solution Approach 1:
The patent merges logging data from multiple sources (mobile phone, network equipment, testing equipment) into a single unified log file. This consolidation eliminates the need for experts to manually align proprietary logging data from different devices, directly resolving the technical contradiction by reducing data alignment complexity while preserving complete diagnosis information.
Solution Approach 2:
The patent introduces a messaging server as an intermediary component that collects and consolidates logging data from various sources. This mediator automatically processes and unifies the data, eliminating the manual alignment process and reducing the complexity burden on experts while maintaining comprehensive diagnostic capability.
2Reliability
If live network testing is performed with real network equipment, then realistic test conditions are achieved, but logging data from network equipment is often unavailable making debugging difficult
Solution Approach 1:
The patent implements a feedback mechanism where the messaging server actively collects logging data from network equipment during live testing and feeds it back to the testing system. This ensures that even during realistic live network testing, the necessary logging information becomes available, maintaining both test reliability and diagnostic capability.
Solution Approach 2:
The messaging server acts as an intermediary that bridges the gap between network equipment and the testing system. It captures logging data from network equipment that would otherwise be unavailable and makes it accessible for analysis, resolving the contradiction between performing realistic live testing and obtaining necessary logging information.
3Measurement precision
If expert intervention is used to diagnose and debug test failures, then accurate problem identification is achieved, but testing efficiency and productivity are reduced
Solution Approach 1:
The patent performs preliminary actions by automatically consolidating all logging data into unified log files before expert analysis is needed. This pre-processing eliminates the time-consuming manual data alignment step, allowing experts to focus directly on diagnosis without reducing overall accuracy, thereby improving testing productivity.
Solution Approach 2:
The system performs self-service by automatically collecting, consolidating, and preparing logging data for analysis without requiring expert intervention for data alignment. This automation handles routine data processing tasks, freeing experts to focus on complex diagnostic problems and improving overall testing efficiency while maintaining diagnostic accuracy.
Data Source
AI summary
A method for validating the operational characteristics of a mobile phone is provided. The message may include sending a message from the mobile phone to network testing equipment. This message may alert the network testing equipment that a debug state of the mobile phone is enabled. The method may also include sending test data from the network testing equipment to the mobile phone. The method may further include receiving the test data at the mobile phone. The method may yet further include creating a log of received data at the mobile phone. In addition, the method may include using short message service signaling to send at least a portion of the logged data from the mobile phone to the network test equipment.
