Service-based core network architecture for 5G with network functions.
Description
The 5G Core (5GC) is a cloud-native, service-based architecture (SBA) that replaces EPC for 5G networks. It consists of modular network functions (NFs) that communicate via HTTP/2-based service interfaces.
Key network functions include AMF (Access and Mobility Management), SMF (Session Management), UPF (User Plane Function), and many others. 5GC supports network slicing, edge computing, and diverse service requirements.
Purpose & Motivation
5GC was designed to:
- Enable network slicing for diverse use cases (eMBB, URLLC, mMTC) - Support service-based architecture for flexibility and scalability - Provide unified access for 3GPP and non-3GPP networks - Enable edge computing with UPF deployment flexibility
