The SMEC Evolved Packet Gateway(ePDG) establishes secure IPsec tunnels between UE & ePDG via WiFi access network while using IKE to authenticate subscribers through the DIAMETER / RADIUS AAA server connected via Diameter or RADIUS. Using GTP or PMIP connections to the P-GW, the ePDG provides mobility support as the subscriber roams between WiFi and LTE network, across WiFi networks(MOBIKE).
