Mobile Core Network Tester

Emulate 3G, 4G, 5G RAN and UEs in software and generate realistic traffic towards the mobile core network.

Overview

The Valid8 Mobile Core Network Tester provides an all-in-one, cost-effective and scalable 3G, 4G, 5G RAN & UE emulator for testing the core network.

What It Can Do For You

The Mobile Core Network Emulator solution is capable of simulating and multiple devices individually or in parallel. Options are available for 3G, 4G and 5G UEs and RAN components.

Example: A network service provider would want to test how their MME & SGW would function under load.

  • Will it properly handle Control plane and User plane traffic?
  • How will it perform under load?

Example: A core network manufacturer wants to test performance and security in a cost-effective way

  • Verify multiple base stations can connect to the core
  • What happens when invalid messages are sent to the core?
  • How will it perform under load?

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

  • Connect on IuCS/ IuPS (3G), S1 (4G), N2 (5G)
  • S1 Flex
  • Realistic network emulation of up to 1,000s of UE devices and 800 TPS per core (scalable)
  • Up to 1Gbs data rate per S1, N2, Iu-CS/PS link
  • Feed in stateful traffic from a 3rd party source
  • True stateful simulation
  • Signaling request/response messages for call handling, mobility management, authentication, QoS
  • 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

Different UE Types:

  • Phone
  • IoT
  • CPE
  • Router
  • Modem

Different RAN Types:

  • NodeB
  • eNodeB
  • gNodeB
  • Pico / Micro / Macro cell

Subsystems

The Valid8 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.

Scripting

The application’s subsystems can be edited directly in the browser using TDL or by using the graphical tools. The Message Workshop allows for creating of test scenarios directly from the hex stream of a remote capture, while the Graphical Editor (on the feature roadmap for 1Q 2020) will allow for creating customized call scenarios by dragging and dropping the call flow to meet your test needs.
