Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single action sequence control method is used between Near-RT RIC and E2 node, then the control process is simple, but it cannot meet the requirement on xAPP MIMO synchronous configuration
Solution Approach 1:
The patent segments the control process into multiple independent action sequences, where each action sequence handles a specific control action. This allows the system to support multiple concurrent control operations (MIMO) while maintaining the simplicity of individual action sequences. The segmentation enables parallel processing of different control actions without increasing the complexity of each individual sequence.
Solution Approach 2:
The patent creates a universal control message structure that can carry multiple control actions with different service styles (Insert, Control, Report) within a single message framework. This multi-functional message structure allows the system to handle various xAPP configuration requirements without creating separate control protocols for each case, thus supporting MIMO synchronous configuration while avoiding excessive system complexity.
2Productivity
If multiple actions are executed in a single action sequence, then interface resource usage increases, but processing delay and failure risk increase when actions are interrupted
Solution Approach 1:
The patent divides multiple control actions into separate, independent action sequences rather than executing them all in one sequence. Each action sequence is self-contained and can be executed independently. This segmentation improves reliability because if one action fails, it does not necessarily cause failure of other actions, and the system can continue processing other action sequences without interruption.
Solution Approach 2:
The patent implements a feedback mechanism where the E2 node sends execution outcomes back to the Near-RT RIC for each control action. This feedback allows the system to monitor the status of each action individually, detect failures early, and trigger appropriate error handling or reconfiguration procedures only for the affected actions, thereby maintaining high overall system reliability while processing multiple actions efficiently.
3Device complexity
If conventional isolated action control method is used, then device processing complexity is low, but resource waste occurs when actions are interrupted and require reconfiguration
Solution Approach 1:
The patent performs preliminary actions by establishing a comprehensive control message structure that includes all necessary control actions and their dependencies before execution begins. The system pre-configures the action sequences and prepares error handling procedures in advance. This preliminary preparation reduces the need for extensive reconfiguration when interruptions occur, as the system already has the framework in place to handle various execution scenarios, thereby reducing resource waste without significantly increasing processing complexity.
Solution Approach 2:
The patent implements a mechanism where failed or interrupted control actions can be discarded and recovered through the feedback loop. When an action fails, the system receives the execution outcome, identifies the failed action, and can retransmit only the necessary control messages for the failed actions rather than restarting the entire control sequence. This selective recovery approach minimizes interface resource waste while maintaining manageable processing complexity.

AI summary
The present disclosure provides a network integration control method and a network integration control device.
