5G Core Network
5G Core (5GC) is the core network architecture of 5G. It is a fundamental component that enables the advanced features and capabilities of 5G networks. The 5G Core network is designed to be more flexible, scalable, and efficient compared to previous generations. It incorporates key technologies like Network Function Virtualization (NFV), Software-Defined Networking (SDN), and Network Slicing to support diverse services, high data rates, low latency, and massive connectivity. The 5G Core network comprises several network functions, including the Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Network Slice Selection Function (NSSF), etc. which work together to provide enhanced connectivity and enable new use cases in the 5G ecosystem.
