Zoom Display for Protocol Message Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the analysis of signalling protocol processes, it is challenging to rapidly and effectively identify procedures that do not conform to specifications, as existing methods require searching through complex dependencies between protocol messages, which is inefficient and not intuitive.
Innovation Solution
A testing device and method that include a storage unit, display unit, and control unit with zoom and shift devices, allowing users to intuitively navigate and adjust the display of messages by increasing or decreasing the number of messages, message types, and direction, as well as switching between different display types and information types, using user-controlled inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users search for errors by analyzing protocol processes sequentially through log files, then comprehensive error detection is possible, but the analysis time and operational complexity increase significantly
Solution Approach 1:
The patent extracts and highlights only the relevant messages and protocol layers necessary for error analysis, separating them from the complete log file. This allows users to focus on critical information without wading through unnecessary data, thereby reducing analysis time while maintaining comprehensive error detection capability.
Solution Approach 2:
The log file is segmented into different protocol layers and message types, allowing users to navigate and analyze specific segments independently. This segmentation enables targeted error detection in specific protocol layers without requiring sequential analysis of the entire log file, significantly reducing analysis time.
2Reliability
If users filter and search through all messages in the log file, then complete coverage of protocol processes is achieved, but the operational complexity and difficulty of identifying relevant messages increase
Solution Approach 1:
The display dynamically adapts to user needs by allowing flexible selection and filtering of protocol layers and message types. Users can easily adjust the view to focus on specific protocol layers or message types without complex filtering operations, making navigation simple while maintaining complete protocol process coverage.
Solution Approach 2:
The patent introduces an intermediary display layer between the raw log file and the user, which automatically organizes and presents messages in a structured manner. This intermediary layer simplifies navigation by pre-processing the log data into an easily navigable format while ensuring complete protocol process coverage.
3Reliability
If all messages from different protocol layers are displayed simultaneously, then complete protocol interaction is visible, but the display complexity and difficulty of identifying error patterns increase
Solution Approach 1:
Messages from different protocol layers are segmented and displayed in a hierarchical structure, allowing users to view complete protocol interactions while maintaining visual organization. This segmentation reduces display complexity by systematically arranging messages according to their protocol layer, making error patterns easier to identify.
Solution Approach 2:
The patent organizes messages in multiple dimensions, including protocol layer hierarchy and message flow sequence. This multi-dimensional organization allows complete protocol interaction visibility while reducing display complexity through structured presentation, enabling users to easily identify error patterns across different protocol layers.

AI summary
A testing device (10) comprises a storage unit (13), a display unit (11) and a control unit (12). The storage unit (13) is embodied to store messages of at least one test performed on at least one device under test. The control unit (12) is embodied to read in at least one part of the messages, to add them to a selection and to display at least an excerpt of the selection in a view on the display unit (11). The control unit (12) provides a zoom device (16), which, in the selection of messages, controlled by a user by means of an operating device (14), is configuredto increase a number of contained messages in the case of a first user entry, and/orto reduce a number of contained messages in the case of a second user entry.
