5G Network Emulator

Emulate 5G core network nodes and generate realistic traffic between network devices

Overview

The Valid8 5G Network Emulator provides an all-in-one, cost-effective and ultra-portable 5G network for demonstration, testing and training purposes.

What It Can Do For You

The 5G Network Emulator solution is capable of simulating and testing several devices individually or in parallel. There are options available to include a real base station (available 1Q2019) if you need to use real UEs or IoT devices with traffic generation, or our simulated RAN if you don’t need the RF interface. Subsystems can be switched on or off depending on how much of the network you need simulated.

Example: A network service provider would want to test how his network would function in a real deployment.

  • Will it properly handle Control plane and User plane traffic?
  • Will it conform to 3GPP standards?
  • 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

  • Emulates some or all of core network, exposing all internal interfaces
  • Can run alongside 4G and 3G core network emulators
  • Conformance tests available for each interface
  • Emulators available per subsystem 
  • OTA connection available for UEs and IoT devices
  • 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

Subsystems

The Valid8 5G Network Emulator is compromised 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.

Scripting

The application’s subsystems can be edited directly in the browser using TDL or by using the graphical tools seen below. The Message Workshop allows for creating of test scenarios directly from the hex stream of a remote capture, while the Graphical Editor allows for creating customized call scenarios by dragging and dropping the call flow to meet your test needs.

Use Cases

eNodeB Under Test

In the scenario where the eNodeB is to be tested, it can be tested by the Valid8 4G Network Emulator emulating the core network. Additionally, load and conformance tests are available for interfaces S1-MME and S1-U. In the case where the eNodeB needs to be tested on the RF side, it can be tested by the Valid8 4G UE Emulator.

Supported Scenarios:
  • ‍Power on / Start up
  • Attach
  • TAU
  • Attach
  • eRAB Setup
  • Detach
  • X2 handover
  • Emulates MME (for S1-MME) and SGW (for S1-U) along with all other needed core network elements, exposing all internal interfaces
  • Conformance tests available for S1-MME, S1-U, and X2

UE Under Test

For testing UE or IoT devices, the 4G Network Emulator can provide the entire 4G core network as well as an emulated or real eNodeB depending on your test needs.

Supported Scenarios:
  • ‍Power on
  • Attach
  • Detach
  • TAU
  • Data Connection
  • VoLTE Call
  • ‍End to end VoLTE test capability
  • Includes real femto, pico, or microcell eNodeB
  • Emulates all core network nodes and allows for data connection to external networks

PGW Under Test

For testing the PGW, the 4G Network Emulator can wrap around the node using the S5/8, S7, and SGi interfaces. Traffic can be originated from real or emulated UE and IoT devices.

Supported Scenarios:
  • ‍Create Session
  • 4 Delete Session
  • 4 Create Bearer
  • 4 Modify Bearer
  • 4 Delete Bearer
  • 4 Echo
  • ‍Emulates all required nodes for wrapping around, including MME and PCRF for testing over interfaces S5/8, S7, and SGi
  • Exposes all internal interfaces
  • Conformance tests available for each interface (S5/8, S7, SGi)

PCRF Under Test

For testing the PCRF, the 4G Network Emulator can wrap around the PCRF with the core network and IMS.

Supported Scenarios:
  • ‍CC-Request / Answer (CCR / CCA)
  • 4 Re-Auth-Request / Answer (RAR / RAA)
  • 4 Capability-Exchange-Request / Answer (CER / CEA)
  • 4 Session-Termination-Request / Answer (STR / STA)
  • 4 Abort-Termination-Request / Answer (ASR / ASA)
  • 4 Device-Watchdog-Request / Answer (DWR / DWA)
  • 4 Disconnect-Peer-Request / Answer (DPR / DPA)
  • ‍Emulates core network, Diameter, and IMS nodes as needed for testing the PCRF, exposing all internal interfaces
  • Conformance tests available for each interface (S7, S9, Rx, Gx)
