Solution Overview
Problem
There is a need to test the impact of various communication services provided by wireless devices on their operation parameters, such as battery lifetime, without a comprehensive method to assess these effects effectively.
Innovation Solution
A test apparatus comprising a transceiver unit, a processing unit, and an output unit, which communicates with the device under test via a wireless link, detects and outputs the communication service used, and can emulate a base station or another device to monitor operation parameters like battery lifetime, and switch between different communication services like 5G, enhanced mobile broadband, massive machine-type, and ultrareliable machine-type services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication services are provided by a wireless device, then service versatility and network capability are improved, but device complexity and operational parameter management become more difficult
Solution Approach 1:
The patent segments the communication services into distinct service types (eMBB, mMTC, uMTC) with specific quality requirements. The test apparatus separately evaluates each service type's impact on operation parameters, allowing complex multi-service devices to be tested through structured, discrete measurement categories rather than monolithic assessment.
Solution Approach 2:
The test apparatus is designed as a universal testing platform capable of evaluating multiple communication services and various operation parameters (battery lifetime, data rate, latency) through a single integrated system. This multi-functional approach simplifies the testing process compared to requiring separate specialized equipment for each service type.
2Use of energy by moving object
If communication services impact operation parameters like battery lifetime, then energy efficiency becomes critical, but measuring and controlling these impacts increases testing complexity
Solution Approach 1:
The test apparatus continuously monitors operation parameters during communication service execution and provides feedback on the impact of different services on parameters like battery lifetime. This feedback mechanism enables quantitative assessment of energy efficiency and allows for controlled testing scenarios where cause-effect relationships can be clearly established.
Solution Approach 2:
The patent systematically varies communication service parameters (data rate, latency requirements, service type) and measures the corresponding changes in operation parameters. By controlling and measuring parameter changes in a structured manner, the complexity of detecting service impacts is reduced through standardized measurement protocols.
3Productivity
If different communication services are tested simultaneously, then testing efficiency is improved, but interference between services makes measurement precision difficult to maintain
Solution Approach 1:
The patent segments the testing process into separate test phases for different communication services. Each service type is evaluated in dedicated time slots or test sequences, preventing interference between services while maintaining high testing throughput. This temporal and logical segmentation allows precise measurement of each service's individual impact on operation parameters.
