dsTest, Developing Solutions, CIoT Testing, C-SGN Testing, C-SGN Emulation, Device Management Gateway, OMA RESTful Network APIs


dsTest supports the Open Mobile Alliance (OMA) Representational State Transfer (RESTful) Network Application Programming Interfaces (APIs) between the Application Server/Services Capability Server (AS/SCS) and the Services Capability Exposure Function (SCEF). The OMA specifies these APIs with HTTP protocol bindings using a REST architecture, for the various individual interface definitions, including naming conventions, content type negotiation, representation formats and serialization, and fault definitions.

These APIs provide the ability to the AS/SCS to obtain information regarding user equipment, including location, various capabilities, and status from the network in general, and specifically from the SCEF.

The implementation of these standardized APIs provides additional features to support CIoT Network Testing with dsTest, with our other CIoT/NB-IoT interface applications.


The flowing APIs have been implemented and are available in dsTest:

  • Terminal Status
  • Messaging
  • Presence
  • Terminal Location (under development)
  • Communication Patterns (under development)
  • Message Broadcast (under development)
  • Device Capabilities (under development)

A complete set of events that can be generated by the dsTest AS node simulator  to the SCEF emulator with the RESTful API application can be found here.

As with all dsTest products, the node configurations and test scenarios are easily defined and configured with XML files that are validated against a published XML Schema to avoid invalid definitions. With our dsClient GUI, you can create, run, and archive tests, capture, graph and archive operational measurements, capture real-time data flows, and manage your dsTest servers and testing scenarios with a standalone application that runs on your PC.

Advanced Testing Features

SmartEvents — Alter application behavior or coordinate multiple interface applications with SmartEvents. Our programmable, subscriber-level state machine gives you the ability to define handlers for specified application events that can then cause an event in another application to be executed. You can also configure handlers to modify subscriber information during run-time, introduce timers, or randomize subscriber behavior based on configurable probabilities to name a few of the many options in one of dsTest’s most powerful features.

SmartMessageElement — Insert, delete, or replace elements in Diameter, RADIUS, MAP, LDAP, GTP, REST, or SOAP messages with our SmartMessageElement solution. Define proprietary signaling or corrupt elements to facilitate negative testing. You can specify when your elements are used with SmartEvents.

Traffic Profile — Draw the shape of your test actions across time with Traffic Profile. You can define the rate for any action as a static rate or reference a Traffic Profile configuration, which also means that multiple Traffic Profiles can be running concurrently. Use Traffic Profile in conjunction with the randomizing features in SmartEvents to design a test that more truly simulates real-world network activity.

Operational Measurements

dsTest provides rich sets of measurements for RESTful interfaces:

  • Transaction and transport layer attempts, successes, and failures
  • Transaction duration, transactions-per-second, and round-trip delay
  • Message and byte counters
  • Errors encountered and error indications received in messages

See our Online Help for Messaging measurements, Presence measurements, Terminal Status measurements, socket measurements, and IP layer measurements.
