	Slide 6, provides a clear problem definition for our ping-pong research. It highlights the two main functional blocks we developed: Ping-Pong Detection: This block identifies ping-pong events after they happen based on handover sequences. The graph on the right shows an example of a ping-pong pattern, where the UE rapidly switches between cells A, B, C, and D within a short time window. Our detection algorithm captures these patterns. Ping-Pong Prediction (Early Alarm): The second block is about predicting ping-pongs at the moment a UE sends a handover request. The bottom graph illustrates this - just as the UE is about to ping-pong, our algorithm raises an early alarm. This enables the Access and Mobility Management Function (AMF) to prevent unnecessary handovers proactively. By breaking down the problem into these two distinct phases - reactive detection and proactive prediction, our approach provides a comprehensive solution for mitigating ping-pong events and their negative impacts on 5G network performance and user experience.
