A node (200) of a communication network determines a hash-based sketch. The sketch may for example correspond to a Count-Min (CM) sketch. The sketch summarizes a number of occurrence of an event for a group of UEs (10). Further, the node (200) receives information representing the number of occurrence of the event for said group of UEs from one or more further nodes (100-1, 100-2, 100-3) of the communication network, e.g., in a further hash-based sketch. The node (200) updates the sketch with the information received from the further nodes (100-1, 100-2, 100-3) and provides the updated sketch to the further nodes (100-1, 100-2, 100-3). |
