Install and Build CN - SantiagoBH/5G-NSA-Network-with-Mosaic5g GitHub Wiki
A Core Network (CN) typically consists of various network elements, Home Subscriber Server (HSS), Serving Gateway (SGW), Packet Data Network Gateway (PGW), and Policy and Charging Rules Function (PCRF), among others. These network elements work together to provide different functions, such as routing and switching of voice and data traffic, authentication and authorization of users, management of subscriber profiles, policy control and charging, and many others.
The CN is a critical component of mobile networks, and its architecture and functionality can vary depending on the type of network technology used. For example, in a 4G LTE network, the CN uses an IP-based architecture, while in a 5G network, the CN is based on a service-based architecture (SBA) that is designed to be more flexible and scalable.
A network 4G has HSS (Home Subscriber Server Entity), MME (Mobility Management Entity), SPGWC and SPGWU.
