Sxa interface is between the SGW (Serving Gateway) C plane and the U plane. Sxb interface is between the PGW (PDN Gateway) C plane and the U plane. Sxc interface is between the TDF (Traffic Detection Function) C plane and the U plane. The Sxa/Sxb/Sxc interface test solution from Valid8 enables conformance or load testing of these interfaces.
Tests the Sxa/Sxb/Sxc interfaces with support for the following messages:
User commands can be fully automated using the HTTP API. This includes performing all test control functions as well as collecting results and metrics.
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.
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.
For testing the AMF, the 5G Network Emulator can wrap around the node using the N1, N2, N8, N11 and N12 interfaces. Traffic can be originated from real or emulated UE and IoT devices
