DATA SHEET CoreSIM: Core Emulation Solution For O-RAN/RAN testing Make Radio Access Network Testing Easier A 4G/5G core simulator, CoreSIM makes Radio Access Network testing easier by eliminating Core Network unwanted dependencies and allowing an easily controllable, repeatable test environment setup. RAN test efforts can thus be concentrated on the Device Under Test, speeding up 3GPP and O-RAN standards implementation. Highly scalable, CoreSIM enables the setup of multiple independent test sessions. Realistic traffic mixes of data, voice, video, or application flows can be created using the built-in traffic generator. Figure 1. Keysight core emulation for LTE and 5G Quality of experience metrics Users have access to hundreds of comprehensive statistics in real-time during text execution with userconfigurable views, or the data can be sent to an upstream server. All statistics are also available after the test completed, in CSV format for post-processing.

Keysight CoreSIM statistics view Advanced filtering functionality is embedded in the tool allowing users to easily investigate any abnormal behavior happening in the network. 5G NSA (Option 3x) and LTE RAN validation In the non-standalone (NSA) network topology, or in case of LTE only RAN, the CoreSIM simulates MME and SGW components over S1-MME and S1-U interfaces. It can be employed as a standalone tool or in combination with Keysight UeSIM, RuSIM or DuSIM emulators, for a complete wrap-around testing of LTE eNodeB, 5G gNodeB or O-RAN O-DU and O-CU components.

In the 5G standalone (SA) topology, the CoreSIM simulates control plane traffic from the AMF over the N1 and N2 interfaces, and user plane traffic from the UPF over the N3 interface towards the NG-RAN. Figure 4. 5GC Core emulation for 5G SA Full automation via REST APIs is available, CoreSIM allows users to create regressions for continuous validation of product quality. Complete RestAPI documentation available, including configuration samples, allowing users to easily integrate it into an existing automation platform or use Keysight’s OpenTAP Automation platform. • Support for 5G Core emulation...

Keysight Open RAN Simulators Cloud Edition CoreSIM runs on top of the Keysight Open RAN Simulators infrastructure, a cloud-native platform which allows multiple Keysight products to run in parallel (CuSIM, DuSIM, CoreSIM and LoadCore). This test solution provides seamless integration on the same infrastructure as the Device Under Test (DUT), sharing the same look-and-feel and functionalities across all products. The Keysight Open RAN Simulators platform can accommodate any type of cloud – public or private – via the deployment of containers or complete Virtual Machines (VMs). Figure 5. Keysight...
