The SCEF Reference ID, the SCEF ID shall be encoded as specified in clause 8.4.4 and 8.4.5 of 3GPP TS 29.336 [69].

The SCEF ID Length indicates the length of the SCEF ID in octets.

The source MME/SGSN shall set the NSUR (Notify SCEF when UE becomes Reachable) flag to "1" to indicate that the target MME/SGSN shall send a notification to SCEF when the UE becomes reachable, if a monitoring event, with the Monitoring-Type is set to "AVAILABILITY_AFTER_DDN_FAILURE", or "UE_REACHABILITY_AND_IDLE_STATUS_INDICATION" or "AVAILABILITY_AFTER_DDN_FAILURE_AND_IDLE_STATUS_INDICATION" or "UE_REACHABILITY".

The source MME/SGSN shall set the NSUI (Notify SCEF when UE becomes Idle) flag to "1" to indicate that the target MME/SGSN shall send a notification to SCEF when the UE gets into idle mode, if a monitoring event, with the Monitoring-Type is set to "UE_REACHABILITY_AND_IDLE_STATUS_INDICATION" or "AVAILABILITY_AFTER_DDN_FAILURE_AND_IDLE_STATUS_INDICATION".

The Remaining Number of Reports indicates the number of reports which are outstanding to be sent to the SCEF. It shall be encoded as specified in clause 8.4.8 of 3GPP TS 29.336 [69].
