Evolved Packet
Data Gateway (ePDG)
Data Gateway (ePDG)
Securing Alternate Connection Paths
Connections paths, particularly from Wi-Fi, are all around us. Securing those paths and integrating them to the cellular network experience is crucial. The Evolved Packet Data Gateway (ePDG) is a virtualized solution providing carrier-grade support of features like Wi-Fi Calling without the risks.
Benefits
Software Based and Virtualized
Running on standard off the shelf servers, the software based ePDG can be flexibly deployed inside the network on bare metal, as a virtual machine or container.
Support up to 1M secure tunnels per 1U server.
Supporting a Seamless Network Experience
Enhance the customer experience with seamless, secure mobility between VoWiFi and VoLTE as well as applying real-time subscriber, session and application intelligence
Highly Secure
Fully authenticate users, secure data transmissions from the device to the core over untrusted cellular access and act as a termination node of IPSec tunnels established.
Benefits
