X2AP Client Test Suite

Client

X2 Application protocol (X2AP) provides control plane signalling between two eNBs in E-UTRAN (or between eNB and gNB for EN-DC) over X2 interface. X2 interface is used in UE related mobility procedures and in global procedures between two eNBs (or one eNB and one gNB for EN-DC). The X2AP Client Suite has been designed to act as a malicious eNB (or gNB for EN-DC) that sends exceptional messages to the tested eNB over X2 interface.
