IMS Core Network Emulator

Emulate IMS network nodes and generate realistic traffic between network devices, including VoLTE IMS, SMS.

Overview

The Valid8 IMS Core Network Emulator provides an all-in-one, cost-effective and ultra-portable IMS network for demonstration, testing and training purposes.

What It Can Do For You

Emulates all necessary IMS core nodes including P/I/S-CSCF, AS and 4G/5G nodes including HSS/UDM and PCRF, connecting on Cx/Dx,Rx, Gx,Gm, Mw, SGi interfaces.

‍

Why It’s Different

Scalable software-based architecture can run on a range of hardware from COTS and high-end customer provided hardware to Virtual Machines and the Cloud (e.g. Amazon AWS) for maximum versatility and performance
Web-based UI is easy to learn
HTTP API enable integration with automation test systems and other equipment
Stateful modeling provides accurate emulation of network elements

Features

Realistic network emulation handline 1,000s of devices and calls (scalable)
Emulates some or all of core network, exposing all internal interfaces
Emulators available per subsystem (CSCF Emulator, PCRF Emulator, etc.)
True stateful simulation
Signaling request/response messages for call handling, authentication, etc.
Report on media received, call connect time, call duration, jitter, packet loss
Generate valid and invalid/negative messages and call-scenarios (fully editable scenarios)
Supports sending invalid messages including malformed, dropped, and misordered packets
Check parameters in messages from SUT and flag errors
3GPP-compliant interfaces
‍Alerts and notifications
Connects to 4G or 5G network emulator

Subsystems

The Valid8 IMS Core Network Emulator is comprised of multiple subsystems that are available individually or in parallel, and are scalable to fit your needs. The individual emulators are controllable through their call controllers, and the traffic can be captured through use of a remote capture tool such as Wireshark.

Automation API

User commands can be fully automated using REST API. This includes performing all test control functions as well as collecting results and metrics. It can be integrated into virtually any CI system via the HTTP API, including Jenkins, CircleCI, Gitlab and others. Includes Autom8 Python framework.

Scripting

The application’s subsystems can be edited directly in the browser using TDL. The Message Workshop allows for the creation of test scenarios directly from the hex stream of a remote capture, while the Composer graphical editor (being deployed for all products in 2021) will allow for creating customized call scenarios by dragging and dropping the call flow to meet your test needs.
