The IMS Border Gateway Test Suite was designed to test the IMS border gateway. It integrates the subscribers and the controller into a single flexible but easy-to-use GUI-driven test bed to perform numerous tests.
The IMS Border Gateway Test Suite interacts with the SIP subscribers via the media plane and with the controller (SPDF/P-CSCF) with H.248/Megaco protocol based on the TISPAN extensions. In a deployed network, the media, SIP and Megaco signaling are synchronized.
Simulating and troubleshooting this environment in a lab to test the IMS border gateway before deployment can be a daunting task if multiple independent test boxes/applications are used to emulate the subscribers and the controller.
