McKinney, TX (May 26, 2014) – Developing Solutions has added a Gateway Emulator to its growing list of Test Solutions for their dsTest suite of 3G/4G/LTE testing solutions.  The Gateway Emulator provides a flexible way to provide various configurations on a single COTS platform, depending upon your testing needs:

  • SSGN/GGSN – test GTPV1 interfaces Gn, Gi;
  • SGSN combined with a GGSN and/or EPC elements such as a SGW;
  • SGW/PGW – test SGI and GTPv2 interfaces S11 (GTPv2-C), S5, S1-U (GTP-U);
  • PGW Emulator  – test the Gn interface to external SGSNs;
  • PGW Emulator – test  the Gi interface to Application Functions (AF) in the Internet;
  • SGSN/DHCP server combination to test the Gn interface to the GGSN;
  • Gateway combinations test Policy and Charging Control interfaces such as Gx, Rx, Ro, and Rf for VoLTE testing, PCC/QoS testing, IMS testing, and general EPC Diameter Routing testing.

Gateway Emulator, Policy Enforcement Gateway, GTPv1, GTPv2, LTE Testing, IMS Testing, PCC Testing, VoLTE Testing

A single platform allows you to maximize testing flexibility, simplifying your testing architecture, and test interworking between 3GPP 3G and the EPC, as specified in 3GPP TS 23.401.

Refer to our Gateway Emulator page for more information, which contains a Use Case on Dynamic Policy Enforcement.  Other dsTest Use Cases can be found here.

About dsTest

dsTest originates, receives, and processes signaling traffic into and from the core network.  Multiple emulated nodes can be coordinated to simulate the UE traffic for complex signaling interactions such as VoLTE.  Unlike some test tools, dsTest provides stateful, standards-based applications that react appropriately to both expected and unexpected events without the need for scripting, simplifying the process of performance testing the signaling core.  dsTest surpasses all other tools with its capacity, its performance, and the ease with which you can customize the scenarios and messages to achieve your testing goals.
