The software-based Mobile Core Network emulator mimics 5g Core (5GC) SA and NSA, LTE 4G EPC, and UMTS 3G Core stand-alone to test the RAN.
Overview
The Valid8 Mobile Core Network Emulator provides an all-in-one, cost-effective and ultra-portable 3G 4G 5G network for demonstration, testing, repair and training purposes.
What It Can Do For You
The Mobile Core Network Emulator solution is capable of simulating and testing several devices individually or in parallel. There are options available to include a real eNodeB OTA if you need to use real UEs or IoT devices with traffic generation, or our simulated eNodeB 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 team of technicians wants to test a base station in the field during deployment.
- Will it properly handle Control plane and User plane traffic?
Example: A repair company wants to test performance of a base station in a cost-effective way
- Verify the base station can connect to the core successfully after repair
- Verify the performance of a UE over the air
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 of up to 1,000s of devices and calls (scalable)
- Emulates some or all of core network, exposing all internal interfaces
- Emulators available per subsystem (MME Emulator, PCRF Emulator, etc.)
- 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
- Diameter CER/A, DWR/A, CCR-I/A, CCR-U/A, CCR-T/A, RAR/A request/response messages
- 3GPP-compliant interfaces
- Alerts and notifications

Subsystems
The Valid8 Mobile 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.

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
PGW Under Test
For testing the PGW, the 4G Network Emulator can wrap around the node using the S5/8, S7, Sxx and SGi interfaces. Traffic can be originated from real or emulated UE and IoT devices.
Supported Scenarios:
- Create Session
- Delete Session
- Create Bearer
- Modify Bearer
- Delete Bearer
- Echo
- Emulates all required nodes for wrapping around, including MME and PCRF for testing over interfaces S5/8, S7, Sxx nd SGi
- Exposes all internal interfaces
- Conformance tests available for each interface (S5/8, S7, Sxx, 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:
gNodeB Under Test
In the scenario where the gNodeB is to be tested, it can be tested by the Valid8 5G Network Emulator emulating the core network. Additionally, load and conformance tests are available for interfaces N1/N2/N3. In the case where the gNodeB needs to be tested on the RF side, it can be tested by the Valid8 5G UE Emulator.
Supported Scenarios:
- Power on / Start up
- Attach/Registration
- Detach/Deregistration
- Session management
- Emulates AMF along with all other needed core network elements, exposing all internal interfaces
