N1 Interface
5G load tester N1 interface NAS over NGAP test solution
5G load tester N1 interface NAS over NGAP test solution
Overview
N1 interface is between the UE (User Equipment) and the AMF (Accessibility & Mobility Management Function). The N1 interface test solution from Valid8 enables conformance or load testing of this interface.
What It Can Do For You
Tests the N1 interface.
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
Subsystems
KPIs
- Requests/Responses, attempts, successes and failures
- Request/Report time
- TPS
- Error counters
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. It can be integrated into virtually any CI system via the HTTP API, including Jenkins, CircleCI, Gitlab and others.
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
AMF Under Test
For testing the AMF, the 5G Network Emulator can wrap around the node using the N1, N2, N8, N11, N12 & N22 interfaces. Traffic can be originated from real or emulated UE and IoT devices
Supported Scenarios:
• General Registration
• Registration with AMFre-allocation
• UE-initiated Deregistration
• Network-initiated Deregistration
• UE Triggered Service Request
• Network Triggered Service Request
• UE Configuration Update procedure for access and mobility management related parameters
• UE Configuration Update procedure for transparent UE Policy delivery
• UE Reachability Notification Request procedure
• UE Activity Notification procedure
• AN Release
UE Under Test
For testing UE or IoT devices, the 5G, 4G or 3G Network Emulators can provide the entire core network as well as an emulated or real base station 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
