   * Secures signaling between different operator networks (inter-PLMN).   * Secures signaling between different operator networks (inter-PLMN).
 +
 +Analytics & Specialized Functions
 +
 +NWDAF - Network Data Analytics Function
 +
 +  * Provides AI/ML-driven insights (e.g. traffic prediction, anomaly detection).
 +
 +SMSF - SMS Function
 +
 +  * Supports SMS services over 5G.
 +
 +LMF - Location Management Function:
 +
 +  * Determines device location (e.g. emergency services)
 +
 +AF - Application Function:
 +
 +  * Represents third-party applications (e.g. video streaming, IoT) that interact with 5GC via the NEF to request services (e.g. QoS adjustments).
 +  * AF is critical for enabling network-aware applications (e.g. adjusting bandwidth for a video call)
 +
 +GMLC - Gateway Mobile Location Center:
 +
 +  * Retrieves device location for external application (e.g. emergency services, logistics). While inherited from LTE, it interfaces with 5GC's LMF for location data.
 +  * GMLC bridges 5GC with legacy location services but relies on LMF for actual positioning in 5G.
 +
 +5G-EIR - 5G Equipment Identity Register
 +
 +  * Validates device identities (IMEI) to block unauthorized/stolen devices.
 +  * 5G-EIR replaces LTE's EIR but serves a similar anti-fraud role.
 +
 +N3IWF - Non-3GPP Interworking Function
 +
 +  * Connects untrusted non-3GPP networks (e.g., Wi-Fi, satellite) to 5GC via secure tunnels (IPsec) and interfaces with AMF/UPF.
