Systems and methods are provided for identifying an alternative network function (NF) service consumer to which a notification regarding an observed event may be sent (in the event that a notification sent to an originally-intended/targeted NF service consumer fails). NF discovery request and response operations between a NF service producer and a data repository (at which a NF profile associated with the NF service consumer is registered) may be performed to identify and receive (as part of a NF discovery response operation), binding indication information. The binding information may be used to determine the aforementioned, alternative NF service consumer to receive the notification.
