XnAP Server Test Suite Data Sheet
Test Suite:
XnAP Server Test Suite

Xn Application protocol (XnAP) provides control plane signalling between two NG-RAN nodes in NG-RAN over Xn interface. Xn interface is used in UE related mobility procedures and in global procedures between two NG-RAN nodes. The XnAP Server Suite has been designed to act as a malicious NG-RAN node that sends exceptional requests to the tested NG-RAN node over Xn interface.
