Evolved Packet Data Gateway (ePDG), a vital role in Wi-Fi Calling (VoWiFi), enables mobile operators to securely connect untrusted non-3GPP IP access networks to trusted 3GPP E-UTRAN/EPC networks. It establishes IPSec tunnels using information obtained from the 3GPP AAA process, to ensure secure communication, the network security and internet working control.
By bridging Wi-Fi access points and mobile networks, IPLOOK ePDG helps expand wireless network coverage and offload traffic from congested cellular networks.
ePDG (Evolved Packet Data Gateway), a vital role in VoWiFi (Wi-Fi Calling), allows users to connect to the mobile network via Wi-Fi hotspots, enjoy high-definition audio and video call, and seamlessly switch between VoLTE.
VoWiFi (Voice over Wi-Fi), or Wi-Fi Calling, is an IMS-based voice calling technology similar to VoLTE. It allows smartphone users to make voice or video calls over Wi-Fi when connected to a Wi-Fi network. Wi-Fi serves as the RAN to access the carrier's EPC and IMS networks.

IPLOOK VoWiFi Solution To Enhance Competitiveness of Operators
Wi-Fi Calling (VoWiFi) is an IMS-based voice calling technology similar to VoLTE. Based on ePDG, HSS/3GPP AAAand IMS, IPLOOK VoWiFi solution enables users to achieve high-definition voice or video calls over Wi-Fi , and seamlessly switch with VoLTE, when accessing the mobile network via Wi-Fi hotpots. Wi-Fi serves as the RAN to access the carrier's EPC and IMS networks.
The VoWiFi solution effectively supplements VoLTE. Operators can retain users and attract a broader user base with VoWiFi, exploring potential revenue streams.
IPLOOK's compact EPC also called "IKEPC500 series", it combines MME, SGW, PGW, HSS, PCRF, IMS and DRA network elements in one X86 COTS platform what are 100% 3GPP compliant, and each of them can support all standard interfaces defined by 3GPP.
The IKEPC500 series consists of IKEPC 510 and IKEPC 520, using a unified EMS (Element Management System) to
reduce OPEX.
The IKEPC500 series can also be deployed in a centralized cloud or at the network edge, allowing a broad range of deployment scenarios.
Mobility Management Entity(MME) is a key component of the standards-defined Evolved Pack Core (EPC) for LTE. It provides mobility session management for the LTE network and supports subscriber authentication, roaming and handovers to other networks.
A Home Subscriber Server(HSS) / Home Subscriber Register(HLR) serves as the primary database repository of subscriber information within a LTE/EPC or IMS network core. By centralising all the subscriber information in a single place it allows the signalling to be separated from policy providing a stream lined, high performing network.
SGW(Serving Gateway)
The SGW node handles the user data traffic, but isn' t responsible for the signaling data used. It transports IP data from UE's to the LTE Core Network. The SGW also routes incoming and outgoing IP packets for better system collaboration and serves as an anchor for the UE when it moves from one eNodeB to another.
PGW (PDN Gateway)
PGW is the network node that connects the EPC to external IP networks. What the PGW does is that it routes packets to and from external IP networks. Beyond that, it also allocates an IP address to all UEs and enforces different policies regarding IP user traffic such as packet filtering.
Policy and Charging Rules Function (PCRF), is the part of the Evolved Packet Core (EPC) that supports service data flow detection, policy enforcement and flow-based charging. It offers a comprehensive solution that enables a new generation service provider to offer multiple use cases that allow them to better control their services and align their revenue with their resources.
