LTE eNodeB EPC Emulator

Emulates LTE eNodeB and EPC to test the UE


Valid8's LTE eNodeB EPC emulator is a hardware-based solution that mimics LTE eNodeB and EPC to test user equipment

What It Can Do For You

Cost effective solution to turn up eNBs and test UEs

Why It’s Different

  • Software based solution can be run on high-end Valid8 or customer hardware/VM to achieve better performance, or in the Cloud (e.g. Amazon AWS) for maximum versatility 
  • Web-based Graphical User Interface provides customer with intuitive, easy access via browser 
  • API’s used (REST, HTTP) enable automated testing using test tools. 
  • Emulated nodes behave exactly as true real nodes, due to Finite State Machine architecture 
  • Testing is scalable across multiple cores and multiple systems


  • Emulates some or all of core network, exposing all internal interfaces 
  • Conformance tests available for each interface (S1, S5, S6a, S7, S11, Rx, Gx, Gy, Ro) 
  • Emulators available per subsystem (MME Emulator, PCRF Emulator, etc.) 
  • OTA connection available for UEs and IoT devices 
  • True stateful simulation 
  • Handover support on X2 and S1 
  • 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 
  • Core network 5G ready


  • S1 Attach Requests/Successes/Fails 
  • S1 Detach Requests/Successes/Fails 
  • S1 Dedicated Bearer Requests/Successes/Fails 
  • Current Active Sessions/ Bearers 
  • Number of Sessions/ Bearers Created 
  • S1 Attach Request Response Time 
  • S1 Dedicated Bearer Setup Request Response Time

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.


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 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
