Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of test parameters and operation patterns is increased to cover all 5G NR combinations, then the comprehensiveness of testing is improved, but the effort and cost of preparing test cases increases dramatically
Solution Approach 1:
The test device automatically acquires terminal capability information from the mobile communication terminal itself, extracts relevant capability information, and generates test cases without manual intervention. The system serves itself by using the terminal's own capability data to create comprehensive test cases, eliminating the need for manual preparation of tens of thousands of test case combinations.
Solution Approach 2:
The system dynamically generates test cases by changing and combining different parameter values based on the acquired terminal capability information. It automatically adjusts test parameters such as frequency bands, bandwidths, and MIMO configurations according to the terminal's actual capabilities, creating relevant test cases without manual specification of each parameter combination.
2Reliability
If manual preparation of test cases is performed for all parameter combinations, then test coverage is improved, but the likelihood of errors and omissions increases
Solution Approach 1:
The system establishes a feedback loop where terminal capability information is acquired from the actual terminal, processed to extract relevant capabilities, and used to generate test cases that accurately reflect the terminal's true capabilities. This automated feedback mechanism ensures test case accuracy without manual verification of each configuration.
Solution Approach 2:
The patent replaces the manual mechanical process of preparing test cases with an automated information processing system. Instead of manually configuring each test case parameter, the system automatically acquires capability information, extracts relevant data, and generates test cases through computational processes, eliminating human error in test case preparation.
3Reliability
If the number of test cases is increased to cover all operation modes, then the completeness of evaluation is improved, but the time and resources required for testing increases
Solution Approach 1:
The system performs preliminary acquisition of terminal capability information before test execution, extracting all relevant capability data in advance. This preliminary action enables the subsequent automatic generation of comprehensive test cases for all operation modes without requiring manual preparation time, thus maintaining completeness while improving efficiency.
Solution Approach 2:
The test device is designed with multi-functionality to handle various operation modes (NSA and SA modes), different frequency bands, and multiple MIMO configurations through a single automated system. This universal approach allows comprehensive evaluation across all operation modes using one integrated test case generation mechanism rather than separate manual processes for each mode.
