Once the UE arrives at the new cell, the MME tells the S-GW to switch the user plane path to the target eNodeB. 3. UE-Requested PDN Connectivity

Understanding call flows is essential for troubleshooting and network optimization. Here are the most critical procedures: 1. The Attach Procedure Once the UE arrives at the new cell,

The interface between the LTE network and external packet data networks (like the Internet). It handles IP address allocation, policy enforcement, and charging. Once the UE arrives at the new cell,

This node manages service policy and dictates charging rules for each user's data session. Fundamental 4G LTE Call Flows Once the UE arrives at the new cell,

The "brain" of the control plane. it handles signaling related to mobility and security for E-UTRAN access. It is responsible for tracking and paging UEs (User Equipment) in idle mode.
