4G UE Emulator / eNodeB Tester

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

WHAT IT CAN DO FOR YOU

The 4G UE Emulator solution is capable of simulating and testing several devices individually or in parallel:

  • 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
  • Includes PHY, MAC, RLC, PDCP, RRC, and NAS layers
  • IP traffic generator (ping, UDP, HTTP)
  • Supports Valid8 VoIP Load Tester (includes VoLTE)
  • UE data pass-thru
  • Automation API
  • Voice Quality Measurement (VQM) for QoS
  • FDD with half duplex or full duplex UEs
  • TDD support now available

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
  • 4 Attach
  • 4 TAU
  • 4 Attach
  • 4 eRAB Setup
  • 4 Detach
  • UE Under
protocol-engine--2
  • 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)
protocol-engine--3
  • 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
protocol-engine--4
  • 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
  • 4 Attach
  • 4 Detach
  • 4 TAU
  • 4 Data Connection
  • 4 VoLTE Call
protocol-engine--5
  • 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)
