Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current testing methods for mobile communication devices are inefficient and lack flexible management, particularly when it comes to testing UICC-related functions such as network provisioning and access, which are essential for ensuring proper device functionality and configuration.
Innovation Solution
A testing system and method that utilizes a testing front end module to transmit and activate a testing profile on a mobile communication device, setting it to a testing mode, and includes a testing controller to perform operational tests, with the capability to emulate a UICC for network-related functions, ensuring secure and managed testing without external UICC providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional testing methods are used for mobile communication devices, then testing can be performed with existing infrastructure, but testing efficiency and management flexibility are insufficient
Solution Approach 1:
The testing system is segmented into distinct functional modules: a testing profile management module that handles profile creation and storage, a testing front-end module that interfaces with the device under test, and a testing controller that coordinates test execution. This modular segmentation improves testing efficiency by allowing independent development and management of each component while reducing overall system complexity through clear separation of concerns.
Solution Approach 2:
Testing profiles are created and configured in advance before actual device testing begins. The testing profile management module prepares test configurations, parameters, and procedures beforehand, storing them as reusable templates. This preliminary action eliminates the need to reconfigure testing parameters for each test run, significantly improving testing efficiency and consistency while reducing manual setup complexity.
2Adaptability or versatility
If external UICC providers are used for testing, then diverse testing scenarios can be achieved, but security risks and unauthorized access increase
Solution Approach 1:
The testing profile management module acts as an intermediary between the testing system and the device under test. It securely manages testing profiles that contain all necessary test configurations and credentials, eliminating the need for external UICC providers. This intermediary approach maintains testing scenario diversity by providing various pre-configured test profiles while ensuring security through centralized, controlled profile management and authentication mechanisms.
Solution Approach 2:
Instead of using external UICC providers, the system creates virtual copies of UICC functionality through testing profiles stored locally in the testing system. These profile copies contain all necessary subscriber information and authentication data needed for testing, providing the same versatility as external providers while eliminating security risks associated with physical UICC cards and unauthorized access.
3Ease of operation
If manual configuration of testing parameters is performed, then flexibility in test setup is maintained, but testing time and operational efficiency decrease
Solution Approach 1:
Testing profiles are prepared in advance with all necessary parameters, configurations, and test procedures predefined. The testing profile management module allows operators to create and save complete test configurations as reusable templates. During actual testing, these pre-configured profiles are simply loaded and executed, eliminating repetitive manual configuration tasks while maintaining full flexibility through the ability to customize profiles for different testing scenarios.
Solution Approach 2:
The system enables dynamic parameter changes within the testing profiles without requiring complete reconfiguration. The testing controller can modify test parameters on-the-fly based on test results or different testing scenarios, allowing operators to maintain flexibility while reducing setup time. Profiles can be easily adjusted and regenerated, combining the benefits of manual flexibility with automated efficiency.

AI summary
A testing method for testing mobile communication devices comprises transmitting, by a testing front end module, a testing profile associated with a Universal Integrated Circuit Card, UICC, to a mobile communication device, activating the testing profile on the mobile communication device, setting, by a testing controller, the configuration of the mobile communication device to a testing mode according to the information of the activated testing profile of the UICC, and performing operational tests on the mobile communication device using a testing front end module of a testing system while the configuration of the mobile communication device is set to the testing mode.
