UE sends a request to the MME via the eNodeB.
S-GW re-routes user data packets to the new target eNodeB to ensure service continuity. 4. EPC and Future Evolution UE sends a request to the MME via the eNodeB
The EPC consists of four primary network nodes, each fulfilling a distinct role: S1-U (User Plane)
Understanding call flows is crucial for debugging and optimization. The following are the most fundamental procedures in an LTE network. S5/S8 (Core Engine Interconnect)
Understanding EPC call flows is crucial for troubleshooting and optimizing the LTE network. The following are the most common procedures [1]. A. LTE Attach Procedure (Initial Registration)
The Attach Procedure is the process where the UE connects to the network to receive IP services.
