Innovation Solution
A mobile terminal test system that automatically adjusts parameters to conform with the 3GPP standard by inputting user values, calculating dependent parameters, and displaying selectable conforming values, facilitating easy execution of tests without user awareness of parameter interdependencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually configure multiple test parameters according to 3GPP standard, then measurement accuracy can be ensured, but operation complexity increases and requires deep standard understanding
Solution Approach 1:
The system automatically performs parameter consistency verification and adjustment without requiring user intervention. The control unit self-services by detecting parameter conflicts and autonomously adjusting them to meet 3GPP standards, eliminating the need for users to have deep standard knowledge while maintaining measurement accuracy.
Solution Approach 2:
The system implements a feedback mechanism where the control unit continuously monitors parameter configurations, verifies consistency against 3GPP standards, and provides real-time adjustments. This closed-loop feedback ensures measurement accuracy is maintained while simplifying user operation through automatic correction of parameter conflicts.
2Reliability
If users manually adjust parameters to conform to 3GPP standard, then standard compliance is achieved, but time consumption increases due to trial and error
Solution Approach 1:
The system performs preliminary verification of parameter consistency before test execution. The control unit proactively checks all parameter configurations against 3GPP standards and pre-adjusts any conflicts, preventing time-consuming trial and error during actual testing while ensuring standard compliance.
Solution Approach 2:
The control unit autonomously verifies and adjusts parameters to meet 3GPP requirements without requiring iterative user intervention. This self-service approach eliminates time loss from manual trial and error while maintaining reliable standard compliance through automated consistency checking.
3Adaptability or versatility
If multiple parameters are independently configurable, then test flexibility increases, but parameter interdependence causes configuration errors
Solution Approach 1:
The system implements feedback control where the control unit monitors parameter configurations and automatically detects interdependence conflicts. When parameter changes affect other parameters, the system provides real-time feedback and automatic adjustment, maintaining configuration accuracy while preserving test flexibility through guided parameter modification.
Solution Approach 2:
The control unit acts as an intermediary between user parameter inputs and the test execution system. It mediates parameter interdependencies by automatically coordinating changes across multiple parameters, ensuring configuration accuracy is maintained while allowing users to freely adjust test conditions for flexibility.

AI summary
A parameter calculation unit that calculates, according to one or more input values of a parameter, a value of another parameter, a standard conformance determination unit that determines whether or not the input value of the parameter and the value of the parameter calculated by the parameter calculation unit conform with a 3GPP standard, a parameter adjustment unit that adjusts a value of a parameter, which does not conform with the 3GPP standard, to a value in conformity with the 3GPP standard, and a conformance and nonconformance determination criterion value calculation unit that calculates a conformance and nonconformance determination criterion value of a test case by using at least one of a parameter having a value determined to conform with the 3GPP standard by the standard conformance determination unit and a parameter having a value adjusted by the parameter adjustment unit are included.
