Open RAN Test Case Control for Integrated Radio and Wired Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional measurement devices are unable to systematically and efficiently control both radio and wired sections of Open RAN components, such as O-RU and O-DU, requiring separate control of signal analyzers and emulators, which complicates testing.
Innovation Solution
A measurement device and method that allows for the selection of Open RAN components as test targets, incorporating a display unit, device control units, and a test case creation unit to manage and execute tests efficiently, including a control target selection and processing component arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional measurement device is used to test mobile communication terminal, then radio section measurement is achieved, but wired section measurement cannot be performed simultaneously
Solution Approach 1:
The measurement device is designed to perform both radio section measurement (using signal analyzer and signal generator) and wired section measurement (using O-RAN DU emulator) within a single integrated system, allowing one device to fulfill multiple measurement functions that previously required separate systems
Solution Approach 2:
The patent combines previously separate measurement systems (radio measurement equipment and wired section measurement equipment) into a single integrated measurement device with unified control, merging the functionality of signal analyzer, signal generator, and O-RAN DU emulator under one system architecture
2Adaptability or versatility
If multiple control target devices are used for Open RAN component testing, then comprehensive measurement is achieved, but systematic control becomes difficult
Solution Approach 1:
The measurement device provides a unified control interface that can systematically control multiple different control target devices (signal analyzer, signal generator, O-RAN DU emulator) through a single software system, eliminating the need for separate control systems for each device
Solution Approach 2:
The patent introduces a central control unit that acts as an intermediary between the user interface and multiple control target devices, coordinating their operations systematically and enabling efficient control of multiple devices through a single point of control
3Measurement precision
If separate systems are used for radio and wired section measurements, then specialized measurement is achieved, but test execution efficiency decreases
Solution Approach 1:
The patent merges radio section measurement functionality and wired section measurement functionality into a single integrated measurement device, allowing both types of measurements to be executed simultaneously or sequentially within one system, thereby improving test execution efficiency while maintaining measurement precision
