The 5G core network, as defined by 3GPP, is a cloud-aligned, service-based architecture that encompasses all 5G functions and interactions, such as authentication, security, session management, and traffic aggregation from end devices.

Good explanation of 5G Core Network architecture. Unlike 4G EPC, the 5G Core is cloud-native and service-based (SBA), where network functions communicate using APIs. Key functions like AMF, SMF, and UPF are separated, which helps improve scalability, lower latency, and network slicing. This modern design makes 5G more flexible, efficient, and future-ready compared to older core networks. For beginners or professionals who want an easy and simple understanding of 5G concepts, TechLTE World also provides clear explanations and practical training on 5G and related technologies.
