Abstract: A network exposure node receives a reference identity for the network exposure node in a first monitoring message from a first network node. The network exposure node further retrieves, based on the reference identity for the network exposure node, an identity list of one or more subscriber UEs, which subscribed to monitoring of an event, and configuration information for the one or more subscriber UEs, which are stored in the network exposure node. The network exposure node then determines, based on the identity list and the configuration information, a second network node associated with a subscriber UE in the identity list. Next, the network exposure node transmits a report for the monitoring of the event in a second monitoring message to the determined second network node.
