dsTest supports both server emulation and client interface simulator capabilities for the 3GPP LTE S6m/S6n Diameter interface. Use the S6m/S6n Interface application on our simulated Machine Type Communications Interworking Function (MTC_IWF) or MTC-AAA to test the capacity and performance of a Home Subscriber Server (HSS). Use our HSS simulator node with the S6m/S6n interface application to test your MTC-AAA or MTC-IWF/CIoT Device Management Gateway. Customize S6m/S6n messages using our SmartAVP feature. If you are testing CIoT/NB-IoT, dsTest can surround a device management gateway with all the interfaces needed to verify the SCEF, MTC-IWF and SCS functions required of the Device Management Gateway. The S6m/S6n reference point is stateless, and is specified in 3GPP TS 29.336.
Comprehensive sets of Operational Measurements for the S6m/S6n application, 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 S6m/S6n application implements the following 3GPP procedures:
- Subscriber Information Request/Answer
The S6m/S6n Diameter application application ID is 16777310, and the vendor identifier is 10415 (3GPP).
A complete set of events that can be generated with the S6m/S6n interface can be found here.
MTC-AAA/MTC-IWF Testing (Server Emulation)
Our HSS server emulator supplies an appropriate response when applicable, eliminating the need to dedicate a production server to lab activities. The S6m/S6n application allows users to validate MTC-IWF/MTC-AAA functionality, performance and capacity in a realistic network environment, replicating a deployment configuration.
HSS Testing (Client Simulation)
The S6m/S6n application simulates a MTC-IWF/MTC-AAA S6m/S6n interface to your HSS to determine the functionality, processing capacity and performance of the HSS. Execute timed chains of test events with a run-time command or during an automated test using our SmartEvents feature to trigger MTC-IWF/MTC-AAA-initiated procedures.
Multiple nodes can be instantiated on a single server, each with scalable subscriber loads and transaction rates. In this mode the S6m/S6n 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.
