Now lets dive into the specific problem we are tackling - the ping-pong issue in 5G networks.
Ping-pong occurs when a User Equipment, or UE, switches back and forth between two cells within a very short time, as shown in the diagram. The UE bounces between the serving cell and target cell rapidly, like a ping-pong ball.
This ping-ponging has several negative impacts on network performance and user experience:
First, it causes control-plane congestion and processor overload, straining the network. Second, the constant handovers lead to higher power consumption for the UE, draining battery faster. Third, ping-ponging reduces service continuity and stability, leading to dropped connections.
Our objective is to detect and predict these ping-pong events using NWDAF analytics, so we can take proactive steps to improve handover performance. By minimizing unnecessary ping-pongs, we can ensure a smoother, more seamless 5G experience for users.
