name: IEF
full_form: Identity Event Function
context: The IEF is the function responsible for observing and detecting identifier association changes within its parent NF and providing those changes in the form of event records to the ICF over LI_XER. IEFs may be co-located with POIs but may also be placed in other NFs where the NFs handling identifier association do not otherwise support POI functionality. The IEF shall be able to provide event records to the ICF when associations are updated. Association events include both allocation or deallocation events for temporary identifiers managed by the IEFâs parent NF and for identifier associations which are registered or deregistered in the IEF's parent NF but the identifier allocation is not controlled by that NF. The IEF shall support activation and deactivation of IEF association reporting capabilities, as controlled by the LICF (proxied by the LIPF) over the LI_XEM1 interface. When IEF reporting capabilities are activated, the IEF shall obtain the current allocation and registration
description: The Identity Event Function (IEF) is a network function responsible for observing and detecting identifier association changes within its parent Network Function (NF) and providing those changes in the form of event records to the Identity Consumption Function (ICF). It plays a crucial role in managing identifier associations, including temporary identifiers managed by its parent NF and registered or deregistered identifier associations.
explanation: The IEF is classified as a Network Function based on its responsibility for observing and detecting identifier association changes within its parent NF, providing event records to the ICF, and supporting activation and deactivation of IEF association reporting capabilities. This classification is justified by the context provided from 3GPP TS 33.127, section 5.7.2.2.
