dsTest supports both server emulation and client interface simulator capabilities for the 3GPP LTE S6t Diameter interface. Use the S6t Interface application on our Home Subscriber Server (HSS) Emulator to test the functionality, capacity, and performance of a Service Capabilities Exposure Function (SCEF). Use our SCEF simulator node with the S6t interface application to test your HSS. Customize S6t messages using our SmartAVP feature. If you are testing CIoT/NB-IoT, dsTest can surround a CIoT Serving Gateway Node (C-SGN) with all the interfaces needed to verify the interface and functions required of the C-SGN. The S6t reference point is stateless, and is specified in 3GPP TS 29.336.
Comprehensive sets of Operational Measurements for the S6t 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 S6t application implements the following 3GPP procedures:
- Configuration Information-Request/Answer
- Non IP Data Delivery(NIDD)-Information-Request/Answer
The S6t Diameter application application ID is 16777345, and the vendor identifier is 10415 (3GPP).
SCEF Testing (Server Emulation)
The HSS 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 by executing a event chain with a run-time command or during an automated test.
HSS Testing (Client Simulation)
Our S6t Interface application simulates a SCEF S66 interface to determine the processing capacity and performance of a HSS. The S6t Interface application allows users to validate HSS 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 S6t 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.
