NEF, located between the 5GC (5G core network) and external third-party application functionaries, is responsible for managing the external open network data, and all external applications that want to access the internal data of the 5G core must pass through the NEF. By opening the network capability to third-party applications, it can realize the friendly connection between network capability and business requirements, improve business experience and optimize network resource allocation. IPLOOK 5GC NEF is being delivered in line with evolving 3GPP standards. NEF provides corresponding security guarantees to ensure the security of external applications to 3GPP network, and provides functions such as open QoS customization ability of external applications, mobility state event subscription, AF request distribution, etc. The NEF communicates with each NF via a southbound interface through a northbound API that provides AF with access to 5GC data or the use of certain functions. 3GPP interface refers to the southbound interface between the NEF and 5GC network functions, such as the N29 interface between the NEF and SMF, the N30 interface between the NEF and PCF, and so on.
