Disclosed herein is a system (200) and a method (400) for detecting ping-pong behavior of user devices in a communication network. The method processes two categories of data logs, one originating from a core network and other from Radio Access Network (RAN) nodes linked to the user devices. After applying multiple preprocessing steps to refine these logs, the method identifies inter-Radio Access Technology (RAT) transitions for each user device and calculates frequency of such transitions within a specified time interval. If the observed frequency exceeds a predefined threshold, the user device is flagged as exhibiting the ping-pong behavior. The method further generates a structured list of affected user devices along with their associated sectors. By accurately detecting excessive inter-RAT transitions, the method provides actionable insights that enable network operators to optimize handover strategies, reduce unnecessary signaling, and improve overall network performance and user experience.
