Radisys Enhances its Mobile Security Gateway with TTG & Wi-Fi Capabilities

Radisys has enhanced its ATCA-based SEG-100 security gateway with new Tunnel Terminating Gateway (TTG) and Interworking Wireless LAN (I-WLAN) functionality for network equipment providers.


The new functionality allows mobile operators to offload traffic in a secure fashion. Specifically, the enhanced SEG-100 offloads traffic using a secure 3GPP standards-based TTG connection. Previously, network equipment providers have created their own TTG capabilities or integrated a standalone TTG box into their environment.

An I-WLAN is a wireless data access solution that allows data traffic to flow between wireless local area networks (WLANs) and the operator's 3GPP systems. Mobile clients, such as laptops, smartphones and tablets, use the WLAN to access the Internet. Radisys' SEG-100 can allow these clients to access the Internet by providing interworking to an existing general packet radio service (GPRS) backbone.

With these enhancements, Radisys noted that its SEG-100 now supports a multitude of security services on a single blade, including LTE network domain security, firewall and an evolutionary path to supporting evolved packet data gateway (ePDG) technologies. It also offers a variety of input/output (I/O) connection options, from front-end Ethernet ports to backplane fabric switches and Rear Transition Modules (RTMs). The TTG/I-WLAN capability can also be extended to be an ePDG for emerging LTE networks. This product is currently in customer trials.
