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, in dual connectivity procedures and in global procedures between two eNBs (or one eNB and one gNB for EN-DC). The X2AP Server Suite has been designed to act as a malicious eNB that sends exceptional messages to the tested eNB (or gNB for EN-DC) over X2 interface.
