Mavenir Systems has announced the availability of its Evolved Packet Data Gateway (ePDG). For subscribers using Wi-Fi, the ePDG provides a secure connection to the Evolved Packet Core (EPC) network and enables seamless mobility between LTE and Wi-Fi.

According Mavenir, its ePDG allows subscribers to maintain constant access to high-speed data and voice services whether they are in LTE coverage areas or using Wi-Fi. The ePDG ensures that data sessions remain active and voice calls stay up while the device switches from LTE to Wi-Fi access.

The ePDG is an integral part of Mavenir’s IMS converged voice solution that is used by mobile operators for both Voice over Wi-Fi (VoWi-Fi) and Voice over LTE (VoLTE). Mvenir provides a converged voice solution that consists of the Telephony Application Server (TAS), Call Session Control Function (CSCF), and aePDG that is optionally integrated with Mavenir’s Packet Gateway (PGW) and Session Border Controller (SBC).
