Solution Overview

Problem

Current Open Radio Access Network (O-RAN) testing is inefficient due to lab-based methods, requiring extensive time and effort for end-to-end validation, numerous test cases, dynamic parameter changes, limited accessibility, asynchronous software releases, and high costs for small companies.

Innovation Solution

A novel automation framework for O-RAN testing that enables remote, cloud-based testing using a split architecture with a front-end portal for user access and a back-end execution module, allowing for simulated or actual component testing, and charging based on resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If lab-based testing methods are used for O-RAN products, then testing can be performed with actual physical equipment, but integration time and end-to-end validation time increase significantly

Engineering Contradiction:
Improvetesting accuracyVSAvoidintegration time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent creates virtual copies of O-RAN network components and test environments in a cloud-based platform. Instead of requiring physical lab equipment for each test, the system uses virtualized network functions and simulated radio access networks that replicate real-world behavior. This allows multiple test scenarios to run concurrently in parallel, dramatically reducing integration time while maintaining testing reliability through standardized virtual environments.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces manual, physical lab-based testing mechanics with automated software-driven testing systems. Test cases are executed automatically through standardized APIs and orchestration layers, eliminating the need for manual setup and teardown of physical test equipment. This substitution of mechanical testing processes with automated digital systems reduces both time and human effort while improving consistency.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If comprehensive test cases are performed for full O-RAN validation, then product reliability is improved, but the number of test cases and complexity increase

Engineering Contradiction:
Improvevalidation completenessVSAvoidtest system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a universal test platform that can execute multiple types of O-RAN test cases across different vendors and network configurations through a single standardized interface. The cloud-based architecture provides multi-functional capabilities to handle connection establishment, data transmission, security validation, and performance testing within one unified system, reducing overall complexity while maintaining comprehensive validation coverage.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent dynamically adjusts test parameters and test case selection based on the specific product being tested and the validation stage. Instead of running all possible test cases for every product, the system intelligently selects and configures relevant test parameters, reducing the effective number of tests needed while maintaining validation completeness through adaptive parameter adjustment.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If cloud-based automation framework is implemented for remote testing, then accessibility and cost are improved, but integration with existing lab systems may become complex

Engineering Contradiction:
Improvetesting accessibilityVSAvoidsystem integration complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces standardized API layers and orchestration intermediaries that bridge cloud-based automated testing and existing lab equipment. These intermediary components provide standardized communication protocols and abstraction layers that enable seamless integration between remote cloud platforms and local physical test equipment, improving accessibility without creating integration complexity for end users.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method for implementing automated testing of an Open Radio Access Network (O-RAN) system in the cloud includes: hosting, in the cloud, the O-RAN test system; triggering an automation suite of an automation framework to execute a pre-defined set of test cases on the O-RAN test system; and transmitting test results including key performance indicators (KPIs) to at least a results repository hosted in the cloud; wherein the automation framework comprises i) a front end module hosted on a public cloud, and ii) a back end module hosted on one of a private cloud and the public cloud, and wherein the front end module and the back end module communicate via an application programming interface. The O-RAN test system comprises at least one of simulated radio units (RUs) and simulated user equipments (UEs) simulated by a test software, and the O-RAN test system is hosted on the public cloud.
