Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pseudo base station apparatus is used to perform communication tests, then the test process and transition state can be detected and displayed, but it becomes difficult to check the settings and state of multiplex communication during tests
Solution Approach 1:
The display information is segmented into different categories including multiplex communication related information, sequence information, and connection state information. This segmentation allows testers to quickly access and check multiplex communication settings without reviewing the entire test log, thereby improving ease of operation and reducing testing time.
Solution Approach 2:
A display control unit is introduced as an intermediary between the pseudo base station control unit and the display unit. This intermediary selectively controls which information is displayed based on test requirements, enabling easy access to multiplex communication settings while filtering out unnecessary information, thus reducing testing time.
2Measurement precision
If testers refer to test sequences and device settings to check multiplex communication, then communication settings can be verified, but it takes a lot of effort and time
Solution Approach 1:
The test device automatically acquires and displays multiplex communication related information directly from the mobile communication terminal during tests. This self-service capability eliminates the need for testers to manually check test sequences and device settings, providing accurate verification while significantly reducing testing time and effort.
Solution Approach 2:
The system provides real-time feedback by automatically acquiring and displaying multiplex communication settings and states during the test process. This immediate feedback allows testers to verify communication settings accurately without time-consuming manual checks, improving both measurement precision and efficiency.
3Reliability
If detailed communication test information is displayed, then comprehensive testing is enabled, but the complexity of the display system increases
Solution Approach 1:
The display information is divided into distinct segments including multiplex communication related information, sequence information, and connection state information. This segmentation allows comprehensive testing to be enabled while keeping the display system manageable, as each segment can be independently controlled and displayed based on test requirements.
Solution Approach 2:
The display control unit dynamically adjusts which information segments are displayed based on the current test state and requirements. This dynamic capability allows the system to maintain reliability through comprehensive information availability while reducing perceived complexity by only displaying relevant information at any given time.

AI summary
It is possible to check the settings of multiplex communication for test or the state of multiplex communication during the test. A test device tests whether a mobile communication terminal, which is a test target, performs a communication operation normally and displays a list of at least the address of the mobile communication terminal and information for identifying a communication partner of the mobile communication terminal as multiplex communication related information when the mobile communication terminal performs multiplex communication on a multiplex communication related display unit 6d of a display unit 6.
