5 Monitoring Event

The Monitoring Events feature monitors specific events in the 3GPP system and makes monitoring event information available using SCEF. It identifies the 3GPP network element suitable for configuring specific events, event detection, and event reporting to the authorized users, for example, for use by applications or logging. If such an event is detected, the network can be configured to perform special actions, for example, limit UE access.

The Monitoring Event procedure requested by SCS/AS is determined from the URI as described in Table 5-5
