Emulate 4G UE and generate realistic traffic towards the eNodeB

Overview

The Valid8 4G UE Emulator provides a cost-effective, scalable, solution for generating realistic UE calls in testing scenarios

What It Can Do For You

The 4G UE Emulator solution is capable of simulating and testing several devices individually or in parallel. It is a scalable solution that enables the generation of up to hundreds of calls over the Uu interface. It is useful for eNodeB feature and capacity testing and any use case where real call generation is needed.

  • It can simulate UEs
  • It can test eNodeB

Why It’s Different

It provides many advantages over using real UEs or basic simulators, including: 

  • Software based UEs are much more flexible in terms of adding new features than real UEs.
  • Real UEs often become obsolete within a few years
  • Easier to execute scripts over large numbers of virtual UEs than on real UEs
  • The HW doesn’t need to change when increasing the number of virtual UEs
  • The band for software based UEs are fully configurable, unlike real UEs
  • TCO (total cost of ownership) for software based UE solution is less expensive than real UEs

Features

  • Scalable architecture
  • 3GPP release 8 - 12

Subsystems

The Valid8 4G 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

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)

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)

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
