5G; 5G System; Network Exposure Function Northbound APIs; Stage 3 (3GPP TS 29.522 version 18.12.0 Release 18)

2Scope / Description

This technical specification defines Phase 3 requirements for the Northbound Interface (NBI) of the 5G System Network Exposure Function (NEF). It specifies the interface between the NEF and external Application Functions (AF) to expose network capabilities, accept application requests, and provide network event notifications. The scope includes traffic influence, device triggering, background data transfer resource management, CP parameter configuration, PFD management, traffic routing influence, change of billing party, QoS requirements for AF, mobile-originated SMS without MSISDN, network configuration parameters, non-IP data transmission, RACS parameter configuration, analytics information exposure, 5G LAN parameter configuration, BDT policy enforcement, enhanced coverage restriction control, IPTV configuration, service-specific parameter configuration, ACS configuration parameters, mobile-originated location requests, AKMA, time synchronization exposure, ECS address configuration, AM policy authorization, AF-triggered access and mobility influence, Northbound EAS deployment management information, MBS management (including TMGI management, session management, parameter configuration, user service management, user data ingestion session management, and group message delivery management), data reporting, UE ID retrieval, media stream event exposure, DNAI mapping, scheduled data transfer negotiation, member UE selection assistance, group parameter configuration, DNN and S-NSSAI-specific group parameter configuration, network slice parameter configuration, network slice usage control parameters, and UE address retrieval, among other functions.
