The NG Application Protocol (NGAP) provides the control plane signalling between NG-RAN node and the Access and Mobility Management Function (AMF). The services provided by the NGAP are divided to UE associated and non UE associated. The UE associated services are related to one UE and the non UE associated services are related to the NG interface. The NGAP is transfered over SCTP. The NGAP protocol is defined in TS 38.413. The NGAP protocol provides transport function between UE and AMF by offering NAS signalling transport. The NAS protocol provides mobility management and session management between the User equipment (UE) and Access and Mobility Management Function (AMF). The NAS protocol is defined in TS 24.501. The NGAP/NAS Server Test Suite has been designed to act as a malicious gNodeB and UE that sends exceptional requests to the tested entity. The supported test target is AMF.
