dsTest supports both server emulation and client interface simulator capabilities for the 3GPP LTE T6a/T6b Diameter interface.  Use the T6 Interface application on our simulated Mobility Management Entity (MME) or Serving GPRS Support Node (SGSN) to test the capacity and performance of a Service Capabilities Exposure Function (SCEF).  Use our SCEF simulator node with the T6 interface application to test your MME, SGSN or CIoT Serving Gateway Node (C-SGN).  Customize T6 messages using our SmartAVP feature.  If you are testing CIoT/NB-IoT, dsTest can surround a C-SGN with all the interfaces needed to verify the MME functions required of the C-SGN.  The T6 reference point is stateless, and is specified in 3GPP TS 29.128.

Comprehensive sets of Operational Measurements for the T6 Interface, Diameter, and socket level are collected at user-specified intervals and stored in a SQLite database on the dsTest server.  Real-time measurements may be retrieved through our dsClient CLI interface or graphed via our dsClient GUI interface.


The T6 application implements the following 3GPP procedures:

A complete set of events that can be generated with the T6 interface can be found here, and our Diameter Dictionary can be used to design, test, validate, and interpret the results of your tests.

The T6 Diameter application application ID is 16777346, and the vendor identifier is 10415 (3GPP).

MME/SGSN Testing (Server Emulation)

The GMSC server emulator initiates the appropriate procedure when appropriate, eliminating the need to dedicate a production server to lab activities. You can manually trigger server-initiated procedures such as Alert Service Center by executing a event chain with a run-time command or during an automated test.

SCEF Testing (Client Simulation)

Our T6 interface application simulates a MME/SGSN T6 interface to determine the processing capacity and performance of a SCEF.  The T6 interface application allows users to validate SCEF performance and capacity in a realistic network environment, replicating the deployment configuration.  Execute timed chains of test events with a run-time command or during an automated test using our SmartEvents feature to trigger SCEF-initiated procedures.

Multiple nodes can be instantiated on a single server, each with scalable subscriber loads and transaction rates. In this mode the T6 interfaces of up to 1000 independent client nodes may be simultaneously simulated.  The nodes are fully independent and their subscriber configurations may also be independent, overlap, or be duplicated.
