Solution Overview
Problem
Testing modern mobile communications terminals, especially smartphones with IP-based communication capabilities, is challenging due to the inability to replicate real-world conditions in laboratory settings, which limits the evaluation of their performance under varying network conditions and IP applications.
Innovation Solution
A test apparatus connected to both the Internet and the mobile communications terminal, capable of testing RF properties and IP applications simultaneously, allowing for comprehensive evaluation under different conditions, including various network standards, field strength, and interference, while measuring power consumption and data transfer efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If testing is performed in the real mobile communications network, then the test results reflect real-world conditions, but the conditions are not reproducible because limiting factors such as cell capacity, timing, and utilization change continuously
Solution Approach 1:
The patent creates a virtual test network that copies the essential characteristics and limiting conditions of a real mobile communications network. This virtual environment reproduces network constraints such as cell capacity, timing requirements, and resource utilization without the variability of actual network conditions, enabling reproducible testing while maintaining realism.
2Stability of the object's composition
If smartphones are tested with IP-based applications in a reproducible test network, then the test conditions are stable and reproducible, but the ability to test under varying real-world network conditions is limited
Solution Approach 1:
The virtual test network is designed to be dynamically configurable, allowing test parameters such as network capacity, timing constraints, and resource availability to be adjusted during testing. This enables the same reproducible test infrastructure to simulate various real-world network conditions by changing virtual parameters rather than physical infrastructure.
3Reliability
If comprehensive testing of RF properties and IP applications is performed simultaneously, then the evaluation is more thorough, but the test apparatus complexity increases
Solution Approach 1:
The patent integrates RF testing capabilities and IP application testing capabilities into a single unified test apparatus. The test device combines traditional RF measurement functions with IP network stack emulation and application-level testing, allowing simultaneous evaluation of both radio frequency performance and higher-layer IP-based application performance through a coordinated testing framework.
