Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If applications are registered through Non-RT RIC to manage base stations, then the flexibility and diversity of application development are improved, but the complexity of managing multiple applications and their interactions increases
Solution Approach 1:
The patent introduces an O1 interface as an intermediary between the Non-RT RIC and base stations, and between applications and base station parameters. This standardized interface mediates the complex interactions between multiple applications and base stations, providing a uniform method for parameter subscription, notification, and adjustment without requiring direct complex point-to-point connections between each application and base station.
2Reliability
If parameter adjustments are made through multiple applications, then the network optimization capabilities are improved, but the difficulty of coordinating parameter changes and maintaining consistency increases
Solution Approach 1:
The patent implements a feedback mechanism where the Non-RT RIC subscribes to base station parameter notifications through the O1 interface. When base station parameters change, the system automatically notifies subscribed applications, enabling them to adjust their behavior accordingly. This feedback loop ensures that multiple applications remain coordinated and consistent with current base station states without requiring complex manual synchronization.
3Reliability
If continuous monitoring of base station status is implemented, then the network performance optimization is improved, but the consumption of system resources and time increases
Solution Approach 1:
The patent implements periodic monitoring where applications subscribe to base station parameter notifications at defined intervals through the Non-RT RIC and O1 interface. Instead of continuous monitoring that would consume excessive resources, the system periodically checks for parameter changes and triggers notifications only when changes occur, reducing system resource consumption and time loss while maintaining effective network performance optimization.
