RAN Intelligent Controller Detection Device for O-RAN Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of standardized test methods or devices for RAN intelligent controllers in open architecture, leading to inconsistencies in their operation and compliance with O-RAN standards across different manufacturers.
Innovation Solution
A detection device and method for RAN intelligent controllers that include a standard database, a communication unit, and a judgment unit. The device sends E2 transmission commands to the controllers, compares the received E2 feedback data with pre-defined E2 qualification data, and determines whether the controllers are in a standard or error state based on the comparison.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple manufacturers develop RAN intelligent controllers independently, then device complexity and innovation increase, but compliance consistency and operational reliability deteriorate due to lack of unified test standards
Solution Approach 1:
The patent establishes a standard database containing predefined standard specified information (E2 transmission commands and corresponding E2 qualification data) before actual testing occurs. This preliminary standardization framework enables consistent compliance verification across different manufacturers' RAN intelligent controllers, resolving the contradiction between manufacturing independence and compliance consistency
Solution Approach 2:
The detection device implements a feedback mechanism where E2 feedback data from the RAN intelligent controller is compared against predetermined E2 qualification data in the standard database. The judgment unit provides binary feedback (standard state or error state) to determine compliance, ensuring reliable and consistent evaluation across different manufacturers while maintaining adaptability
2Reliability
If unified test standards are implemented across all manufacturers, then compliance consistency improves, but device complexity increases due to standardized testing infrastructure requirements
Solution Approach 1:
The detection device is segmented into three distinct functional modules: a standard database for storing standard specified information, a communication unit for E2 interface data transmission and reception, and a judgment unit for compliance determination. This segmentation organizes the testing infrastructure into manageable components, reducing overall device complexity while maintaining compliance consistency
Solution Approach 2:
The patent uses predetermined E2 qualification data stored in the standard database as a reference copy for comparing against actual E2 feedback data. This copying approach simplifies the testing process by eliminating the need for complex real-time analysis, reducing device complexity while ensuring reliable compliance verification

AI summary
A detection device and a detection method of a RAN intelligent controller in open architecture are provided. The detection device includes a standard database, a communication unit, and a judgment unit. The standard database includes multiple pieces of standard specified information, each of which includes an E2 transmission command and E2 qualification data that match each other. The communication unit includes a sending module and a receiving module. The sending module can send the E2 transmission command to a near-real time radio access network intelligent controller, so that the near-real time radio access network intelligent controller can be connected to an evolved node B and a next generation node B through an E2 interface for sending E2 feedback data to the receiving module. The judgment unit selects a matching one of the E2 qualification data according to the E2 transmission command for comparison with the E2 feedback data.
