The Evolved Packet Core (EPC) is the all-IP backbone of 4G LTE networks, designed to deliver high-speed data and integrated voice services by replacing legacy circuit-switched systems with a flattened, packet-switched architecture. Unlike 2G and 3G, where voice and data were handled separately, EPC treats all traffic as IP-based applications, improving efficiency and reducing latency. Core Architecture and Components

1. RRC Connection: The UE establishes a Radio Resource Control connection with the nearest eNodeB.
2. Attach Request: The UE sends an "Attach Request" message containing its IMSI or GUTI to the MME via the eNodeB.
3. Authentication:
