The E-UTRAN uses a simplified single node architecture consisting of the eNodeBs (E-UTRAN
Node B). The eNB communicates with the Evolved Packet Core (EPC) using the S1 interface,
specifically with the Mobility Management Entity (MME) and Serving Gateway (S-GW) using S1-U
interface. The PDN Gateway (P-GW0 provides connectivity to the external packet data networks.
