Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for storing and processing measurement results from conformance tests of mobile communications devices are inefficient, leading to data loss and high computational complexity, especially when dealing with large numbers of measurement results and lengthy test procedures.
Innovation Solution
A measuring device that stores signaling and measurement results in a single binary storage file, allowing for efficient searching and sorting based on user-selectable criteria, and includes a log server to prevent data loss during system crashes, enabling parallel testing across multiple communication standards and storing data as it occurs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If measurement results are stored in one large XML-file, then all measurement results can be stored centrally, but processing becomes very difficult and data loss risk increases
Solution Approach 1:
The patent divides the measurement results into multiple individual XML-files, each containing a specific measurement result with its associated signaling. This segmentation allows for easier processing, sorting, and reduced risk of total data loss, as each file can be handled independently rather than managing one large XML-file containing all results.
2Productivity
If XML-files are stored at the end of test case, then disk operations are minimized for performance, but data loss risk increases in case of system crash
Solution Approach 1:
The patent implements a log server that performs preliminary storage actions by saving each measurement result to an individual XML-file immediately when it is received, rather than waiting until the end of the test case. This preliminary action ensures data is persisted to disk before potential system crashes, reducing data loss risk while maintaining test execution performance.
3Adaptability or versatility
If abstract TTCN instructions are compiled for different measuring devices, then conformance tests can be performed across multiple devices, but device-specific adaptation complexity increases
Solution Approach 1:
The patent creates a universal XML-file format that can store measurement results from different communication standards (UTRAN, E-UTRAN, GERAN, etc.) and different test types. This universal format eliminates the need for device-specific file formats, allowing the same storage and processing approach to work across multiple measuring devices while maintaining cross-device compatibility.
4Ease of manufacture
If signaling and measurement results are stored separately, then data organization follows traditional structure, but processing efficiency decreases for large datasets
Solution Approach 1:
The patent merges the signaling and measurement result into a single XML-file unit, where each file contains both the signaling data and its corresponding measurement result. This merging allows for more efficient processing, as the complete test data unit can be handled together, enabling faster sorting, searching, and analysis compared to managing separate signaling and result files.

AI summary
A measuring device is provided for performing one or more of a protocol test and a conformance test of a device under test. The measuring device comprises a measuring unit configured to perform measurements by transmitting signaling to the device under test and to receive measurement results from the device under test. The measuring results comprise one or more of messages and numerical values. The measuring device comprises a storage unit configured to store the signaling and the measuring results in a single binary storage file. The measuring device comprises a searching unit configured to search the storage file for at least one first measuring result based on user-selectable criteria and to generate an output file comprising only the at least one first measuring result.
