Gx interface test solution

Overview

Gx interface is between the PCEF and PCRF. The Gx interface test solution from Valid8 enables conformance or load testing of this interface,

What It Can Do For You

Tests the Gx interface.

Why It’s Different

  • Software based solution can be run on high-end 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

Features

Subsystems

KPIs
  • Credit Control Requests/Answers Initial, Update and Terminate (CCR/A-I/U/T)
  • Abort Requests/Answers (ASR/A)
  • Reauthorization Requests/Answers (RAR/A)
  • Session Termination Request/Answers (STR/A)
  • Successful and Unsuccessful answers
Configurable Parameters
  • ‍Call session length
  • Concurrent calls/endpoints
  • BHCA/CPS

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 Javascript 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

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)
