Automated RAN Update Testing With Selective Radio Head Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in the radio access network (RAN) wireless testing industry is the complexity and inefficiency in testing software and hardware updates across various devices, including 4G, 5G, and ORAN, due to frequent software updates and interoperability issues.
Innovation Solution
An intelligent system that periodically scans the RAN for updates, selectively activates remote radio heads and mobile devices, and executes a reduced set of test cases based on hardware and software status, using databases to manage and analyze communication logs for quality control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If every RAN-related software and hardware update is tested with every device software, then quality control and system interoperability are improved, but testing complexity and time consumption increase significantly
Solution Approach 1:
The patent segments the testing process by categorizing devices into groups based on their software versions, hardware types, and compatibility profiles. Instead of testing every update with every device individually, the system divides the device population into segments that share common characteristics, allowing representative sampling from each segment to validate updates efficiently while maintaining comprehensive quality control coverage.
2Reliability
If every RAN-related software and hardware update is tested with every device software, then system interoperability is improved, but time consumption increases significantly
Solution Approach 1:
The patent implements preliminary action by pre-establishing device compatibility profiles, software version mappings, and update dependency relationships before actual testing begins. The system performs preliminary analysis to identify which device-update combinations are most critical for testing based on usage patterns, compatibility data, and update impact assessments. This preliminary preparation enables the system to focus testing resources on high-priority combinations, significantly reducing overall testing time while ensuring system interoperability.
3Measurement precision
If comprehensive testing of all updates across all devices is performed, then quality control accuracy is improved, but resource consumption and testing overhead increase
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting testing parameters such as test case selection, testing depth, and validation criteria based on the specific update being tested, the device category, and historical quality data. The system modifies testing parameters in real-time to optimize the balance between accuracy and efficiency - for example, applying more rigorous testing to critical updates affecting core functionality while using streamlined testing for minor feature updates, thereby maintaining quality control accuracy while improving overall testing efficiency.
Data Source
AI summary
The system scans a RAN associated with a wireless telecommunication network to obtain an indication of a hardware status and a software status associated with the RAN. The system determines whether there is an update to the hardware or software status associated with the RAN. Upon determining there is the update, the system obtains from a first database an indication of a remote radio head configured to test the update. Based on the indication of the remote radio head, the system obtains from a second database multiple UEs configured to test the update. The system tests the update by causing the remote radio head to send a communication to a UE among the multiple UEs. The system obtains logs associated with the communication and, based on the logs, determines whether the update passes the tests.
