Initiated when the UE has data to send or receive while in idle mode, re-establishing the radio and S1 bearers. Ensures seamless connectivity as a UE moves between cells. Intra-frequency handovers occur when the UE stays on the same carrier layer. Tracking Area Update (TAU):

The MME instructs the S-GW and P-GW to create a session (Create Session Request). Initiated when the UE has data to send
: The MME sends an Initial Context Setup Request to the eNodeB to establish the data tunnels ( S1-U ).
The central database. It contains subscription-related information, user profiles, and authentication keys. Tracking Area Update (TAU): This public link is
The Attach Procedure is the process where a UE (User Equipment) connects to the LTE network for the first time or after being disconnected.
The process of moving from one tower (eNodeB) to another without dropping the call. Can’t copy the link right now
Before a single byte of the show downloads, the EPC builds a logical "pipe" called a Default Bearer . The S-GW (Serving Gateway) and P-GW (Packet Data Network Gateway) work in tandem. The P-GW is the critical bouncer to the internet—it assigns your phone an IP address and applies the policy. This is where PCRF (Policy and Charging Rules Function) decides: "High-definition video? Yes. But throttling? Not for our premium user."
The Evolved Packet Core (EPC) is the framework that unified voice and data on 4G LTE networks. By replacing legacy circuit-switched networks with a fully flat, Internet Protocol (IP)-based architecture, the EPC significantly reduced latency and maximized data throughput.
