HSS Emulator

Emulates the HSS over S6a to the MME

Overview

Valid8's HSS emulator is a software-based solution that mimics a real HSS to test the rest of the core and user equipment.

What It Can Do For You

Cost effective solution to turn up eNBs, EPCs and test UEs

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 the S6a interface
  • True stateful simulation 
  • Supports authentication and location update and other scenarios
  • Report on messages received, response time, session duration
  • 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 interface
  • Core network 5G ready

LTE-M:

  • Release 14 compliant
  • Category M1 UE support
  • TM6 and TM9 support
  • FDD only (FDD and HD-FDD UEs are supported)
  • Support of multiple CE levels (only CE-Mode A is supported)
  • Support of message repetition for MPDCCH, PDSCH and PUSCH in full duplex (only MPDCCH, PDSCH and PUSCH supported)
  • Support of localized MPDCCH transmission
  • EPDCCH support for Category M1
  • No frequency hopping
  • Bandwidth must be >= 5 MHz for cells that also need to support Category 0 and above UEs

 NB-IOT:

  • Release 14 compliant
  • Single-tone and multi-tone category NB1 and NB2 UE support
  • 15 kHz and 3.75 kHz subcarrier spacing are supported
  • All operation modes (in-band, guard band and standalone) are supported
  • Multiple NB-IoT and LTE cells can be used at the same time in the same eNodeB
  • Support of multiple coverage levels
  • Support of all NPDCCH, NPDSCH, NPUSCH and NPRACH configurations
  • Support of control plane CIoT optimization
  • Support of multi-DRB mode

Subsystems

KPIs
  • S6a Authentication Request Response Time 
  • S6a Update Location Request Response Time
Configurable Parameters
  • PLMN Mobile Country Code (MCC), Mobile Network Code (MNC)
  • IMSIs list
  • Integrity Algorithm 
  • APN list
  • K
  • OPC

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. The Message Workshop allows for creating of test scenarios directly from the hex stream of a remote capture, while the Graphical Editor (on the feature roadmap for 2019) will allow 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
