Methods, network function nodes and computer readable media for event report management

A method at a second Network Function, NF, node for managing an event report for an event exposure service for a User Equipment, UE, from a first NF node which provides the event exposure service, the method comprising:

• transmitting an indicator to the first NF node indicating that the second NF node supports a report mute feature;
• and
• receiving from the first NF node an event report comprising a number of suppressed event reports, the number of suppressed event reports being equal to a number of event reports for the UE that otherwise would be transmitted from the first NF without the report mute feature, the event report further comprising an event report stable time, the event report stable time being a length of time from the time when the first NF node transmits a previous event report to the time when the first NF node transmits the current event report.

A method implemented at a second Network Function, NF, node for managing an event report for an event exposure service for a User Equipment, UE, from a first NF node which provides the event exposure service, the method comprising:

• transmitting to the first NF node an event filtering indicator indicating a presence state of the UE which triggers the event report to the second NF node;
• and
• receiving from the first NF node an event report comprising a number of suppressed event reports, the number of suppressed event reports being equal to a number of event reports for the UE that otherwise would be transmitted from the first NF without the report mute feature, the event report further comprising an event report stable time, the event report stable time being a length of time from the time when the first NF node transmits a previous event report to the time when the first NF node transmits the current event report.
