Fast MCG Link Recovery via UE Feedback Reporting

The patent implements a feedback mechanism where the UE reports first information (including timing feedback information) to the network side, and the network side provides second information back to the UE. This feedback loop enables continuous optimization of the fast MCG link recovery mechanism, allowing the system to learn from actual performance data and adjust parameters to achieve both fast recovery and good service experience.

The patent focuses on optimizing parameter configurations (such as timer durations and threshold values) of the fast MCG link recovery mechanism. By analyzing the reported first information and adjusting these parameters dynamically, the system can resolve the contradiction between achieving fast connection recovery and maintaining good service experience.

The patent divides the information reporting into structured segments: the UE reports specific first information (including timing feedback information about when feedback messages were received relative to timer expiration) in a standardized format. This segmentation makes the reporting process manageable and parseable by the network side, reducing the complexity burden while still providing sufficient data for optimization.

The UE autonomously collects, processes, and reports the first information without requiring complex network-side intervention. The UE self-manages the information gathering process (recording timing data, determining feedback receipt status) and initiates the reporting, reducing the overall system complexity while maintaining high optimization efficiency.
