Perfect for: 📶 Telecom engineers 📶 4G/5G core network beginners 📶 Students preparing for LTE certifications (e.g., NSE, CWNA)

UE sends a request to the MME via the eNodeB.

: Primarily in the user plane, it routes and forwards data packets between the eNodeB (base station) and the PGW. It also acts as an anchor point when a user moves between cells. Perfect for: 📶 Telecom engineers 📶 4G/5G core

The P-GW issues a Create Bearer Request to the S-GW, which passes it to the MME.

Understanding network identifiers is crucial for reading logs and call flows: The P-GW issues a Create Bearer Request to

The P-GW receives a policy update from the PCRF requiring higher QoS parameters for a specific application traffic detection template.

For those looking to dive deeper into the packet-level details, downloading 3GPP technical specifications is the gold standard. The is the IP-based core network architecture for

The is the IP-based core network architecture for LTE, designed to replace the legacy 2G/3G network cores (GPRS/UMTS). It offers a flat, non-hierarchical architecture that reduces latency and allows for faster packet switching, supporting high-speed data services, Voice over LTE (VoLTE), and seamless mobility.

A central database containing subscriber-profile information, authentication credentials, and roaming permissions.

LTE is designed to save battery. When you stop using data, the network moves the UE to . When you tap a web browser link, the following happens:

In previous generations, voice and data were handled separately. EPC consolidates everything onto a single, unified IP service architecture. This convergence allows operators to manage quality of service, enforce data limits, and support handovers seamlessly.
