Implementing a new interface between Near-Real-Time RIC (near-RT RIC) and Non-Real-Time RIC (non-RT RIC) to enable direct control of O-RU parameters, utilizing AI/ML models for dynamic configuration of O-RU components such as PA, ADC, and antenna tilt, and enabling real-time data collection and monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a new direct interface between RIC and O-RU is implemented, then intelligent configuration capability is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary service model consisting of service registration, service discovery, and service execution mechanisms. This intermediary layer enables the RIC to indirectly control O-RU components through a standardized interface framework, resolving the complexity issue by providing structured mediation rather than direct complex connections.
Solution Approach 2:
The control functionality is segmented into separate service modules that can be independently registered and discovered. The interface is divided into distinct service types (configuration service, control service, monitoring service) allowing the system to manage complexity through modular functional decomposition.
2Productivity
If direct control interface is added between RIC and O-RU, then control efficiency is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal service-oriented interface framework that can handle multiple control functions (configuration, control, monitoring) through a single standardized mechanism. This multi-functional approach improves control efficiency without proportionally increasing complexity, as the same interface infrastructure serves multiple purposes.
Solution Approach 2:
Service registration and service discovery mechanisms are established in advance before actual control operations. This preliminary setup creates a ready-to-use interface framework that enables efficient real-time control without ad-hoc complexity during operation.
3Adaptability or versatility
If AI/ML models are used for dynamic configuration, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent enables the O-RU components to self-configure based on service instructions received from the RIC. The Power Amplifier, ADC, and antenna systems automatically adjust their parameters according to the service execution framework, reducing the need for complex external control logic and enabling adaptability through self-service mechanisms.
4Ease of operation
If service-oriented interface framework is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The monitoring service component provides feedback mechanisms that allow the RIC to observe the state of O-RU components and adjust service instructions accordingly. This feedback loop simplifies operation by enabling automatic adjustments based on real-time status information, reducing manual intervention complexity.
