AI Technical Summary
Technical Problem
Existing AI/ML models in wireless communication systems have an expiration date and deteriorate in performance, necessitating retraining to maintain optimal mobility of user equipment (UE), but current methods lack efficient mechanisms for timely retraining.
Method used
A wireless base station equipped with an AI/ML model unit that monitors performance and transmits feedback on handover, radio link failures, and beam failures to an operations and maintenance entity, enabling dynamic retraining based on occurrence rates and performance thresholds.
Benefits of technology
This approach ensures optimal mobility of user equipment by maintaining the performance of AI/ML models, minimizing call drops, radio link failures, and unnecessary handovers through timely retraining.

Abstract
To achieve optimal mobility of the UE using the AI / ML model while maintaining the performance of the AI / ML model. [Solution] The wireless base station includes a control unit that executes a terminal mobility optimization procedure based on the results of model inference using a learning model, a receiving unit that receives a request from an entity that performs operation and maintenance to transmit information regarding terminal handover, wireless link, or beam failure in the mobility optimization procedure, and a transmitting unit that transmits a message containing the information regarding the failure to the entity in response to the transmission request.
