The Valid8 4G UE Emulator provides a cost-effective, scalable, solution for generating realistic UE calls in testing scenarios
The 4G UE Emulator solution is capable of simulating and testing several devices individually or in parallel. 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.
It provides many advantages over using real UEs or basic simulators, including:
The Valid8 4G Network Emulator is compromised of multiple subsystems that are available individually or in parallel, and are scalable to fit your needs. The individual emulators are controllable through their call controllers, and the traffic can be captured through use of a remote capture tool such as Wireshark.
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.
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.
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.
For testing the PCRF, the 4G Network Emulator can wrap around the PCRF with the core network and IMS.
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 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.
