Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of E2 terminations in electronic devices leads to increased data transmission paths and load, reducing data reception stability in open RAN systems.
Innovation Solution
An electronic device with a RAN intelligent controller (RIC) that includes a traffic controller to select and manage E2 terminations based on traffic information, optimizing data transmission paths and reducing overload by connecting nodes with similar data types to the same termination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of E2 terminations is increased to handle more nodes, then the load capacity of the RIC is improved, but the number of data transmission paths increases causing reduced data reception stability
Solution Approach 1:
The patent segments the data transmission paths by grouping nodes with similar data types to the same E2 termination. This segmentation reduces the number of transmission paths while maintaining the ability to handle diverse traffic types, thereby improving data reception stability without sacrificing load capacity.
Solution Approach 2:
The patent applies local quality by assigning different data types to different E2 terminations based on their characteristics. Nodes transmitting similar data types are grouped together, creating specialized transmission paths that improve reliability for each data type while managing overall system load efficiently.
2Productivity
If multiple E2 terminations are implemented to reduce termination load, then the processing capacity is improved, but the complexity of data transmission paths increases
Solution Approach 1:
The patent merges nodes with similar data types to the same E2 termination, reducing the number of transmission paths and simplifying the overall system architecture. This merging maintains processing capacity by distributing different data types across multiple terminations while reducing path complexity through consolidation of similar traffic flows.
