UE sends a Service Request to the MME via eNodeB.

: The user-plane node that routes and forwards IP data packets between the eNodeB and the core network. It acts as a local mobility anchor during handovers between base stations.

Stores cryptographic keys used by the MME to authenticate the UE.

The package includes:

This flow details how a device registers with the network to obtain an IP address and setup default internet connectivity.

The HSS is a central database containing user-related and subscription-related information.

Enables native support for Voice over LTE (VoLTE) and high-speed data services. 2. Fundamental EPC Network Components UE sends a Service Request to the MME via eNodeB

: The MME verifies the device status and initiates security validation.
