The MME receives confirmation from the gateways, responds to the UE with a Detach Accept (if the device is still reachable), and clears the user's active session memory from its routing tables. 4. EPC Evolution: Moving Toward 5G (NextGen Core)
MME or Source eNodeB triggers the handover.
The P-GW acknowledges deletion, and the MME responds to the UE with a Detach Accept before releasing the radio resource control context at the eNodeB. Reference Summary Table Metric / Layer 4G LTE EPC Architecture Features Domain Type All-IP Packet-Switched (PS) Network Control Nodes MME, HSS, PCRF User Nodes S-GW, P-GW Default Bearer Established at boot; Non-GBR status Dedicated Bearer Triggered on-demand; Handles GBR streams Interfaces The MME receives confirmation from the gateways, responds
The MME requests security vectors from the HSS. It challenges the UE, checking its credentials to confirm it is a valid subscriber.
This comprehensive technical guide breaks down the core concepts of the 4G EPC network architecture and provides step-by-step breakdowns of essential call flows, including Attach, Detach, and Dedicated Bearer Activation. Introduction to 4G LTE Evolved Packet Core (EPC) The P-GW acknowledges deletion, and the MME responds
A massive database containing subscriber profiles and authentication keys.
Fewer network nodes, reducing latency and simplifying network management. This comprehensive technical guide breaks down the core
Analyze how the P-GW communicates with the IMS core to deliver high-quality voice over the packet-switched network.
The MME is the primary control plane node in the EPC. Its roles include:
