The Evolved Packet Core (EPC) is a key component of the 4G LTE (Long-Term Evolution) network architecture. It provides a high-speed, all-IP network for delivering mobile broadband services. The EPC is responsible for managing user sessions, routing data packets, and providing connectivity to the internet and other IP networks.
The source eNodeB determines a handover is needed based on signal strength and sends a request to the MME. The Evolved Packet Core (EPC) is a key
Acts as an "anchor" for user data as devices move between different cell towers (eNodeBs), ensuring the connection doesn't drop. The source eNodeB determines a handover is needed
The EPC is composed of several key logical nodes, each handling specific functions of the call flow and data session: Data packets are buffered and forwarded to prevent loss
The UE is instructed to switch to the target eNodeB. Data packets are buffered and forwarded to prevent loss.
