Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X2 interface linking, planning, or construction methods in O-RAN systems are inefficient or inaccurate, leading to poor performance, missed X2 links, and inefficient resource usage due to technological mismatches and outdated architecture.
Innovation Solution
A system and method that include receiving reporting data from master and secondary nodes, determining if an interface link between them is established, and establishing the link if it is not, to efficiently identify and create X2 links, thereby addressing deficiencies in technological evolution and architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional X2 interface linking methods are used, then network architecture is maintained, but link identification accuracy deteriorates and resource usage becomes inefficient
Solution Approach 1:
The system implements feedback mechanisms by continuously monitoring reporting data from master and secondary nodes, analyzing whether interface links are properly established, and automatically triggering link establishment procedures when deficiencies are detected. This closed-loop feedback approach significantly improves link identification accuracy compared to traditional static configuration methods.
Solution Approach 2:
The network system performs self-diagnosis and self-configuration by automatically analyzing reporting data to identify missing X2 links and initiating the link establishment process without external intervention. This self-service capability eliminates manual configuration errors and improves both identification accuracy and resource efficiency.
2Ease of manufacture
If manual X2 interface configuration is used, then implementation simplicity is maintained, but link establishment completeness deteriorates
Solution Approach 1:
The system automatically analyzes reporting data from network nodes to identify missing X2 links and initiates link establishment procedures without requiring manual intervention. This self-service approach maintains implementation simplicity while dramatically improving link establishment completeness by eliminating human error and oversight.
Solution Approach 2:
The system continuously monitors network reporting data to detect missing links and automatically triggers corrective actions. This feedback-driven approach ensures complete link establishment while requiring minimal manual configuration, effectively combining simplicity with reliability.
3Measurement precision
If automated link detection is implemented, then link identification accuracy improves, but system complexity increases
Solution Approach 1:
The system leverages existing self-service capabilities in O-RAN networks by having nodes automatically generate and send reporting data about their interface link status. The microservice analyzes this existing data to identify missing links, achieving high identification accuracy without adding significant system complexity beyond the analytical layer.
Solution Approach 2:
The patent introduces a lightweight microservice as an intermediary that sits between existing network nodes and the core network functionality. This intermediary analyzes reporting data from multiple nodes and coordinates link establishment, providing accurate link detection while isolating complexity to a single manageable component rather than distributing it throughout the entire system.

AI summary
A network testing system includes a non-transitory computer readable medium configured to store instructions thereon, and a processor. The processor is configured to execute the instructions for receiving first reporting data associated with a master node for a first group of users. The processor is configured to execute the instructions for receiving second reporting data associated with a secondary node for a second group of users. The processor is configured to execute the instructions for determining whether an interface link between the master node and the secondary node has been established. The processor is configured to execute the instructions for establishing the interface link between the master node and the secondary node, in response to a determination that the interface link is not established.
