Actions in response to primitives.

GTS primitive/5G component	User equipment (UE)	gNB	AMF	UPF	AUSF/UDM	SMF
Reserve	Locate one specific UE and connect	Ensure that the gNB is available on the testbed	Instantiate AMF VNF	Instantiate UPF VNF	Instantiate AUSF VNF	Instantiate SMF VNF
Activate	Attach to 5G slice	Activate N2, N3 interfaces to the correct AMF, UPF and start PLMN broadcast	Connect interfaces N8, N11, N12 with the rest of the components	Connect interfaces N4, N6 with SMF and DN	Register user credentials and keys, connect to AMF	Configure UE IP address pool, traffic steering, connect to AMF/UPF
Deactivate	Detach from 5G slice	Close logical association with AMF/UPF	Disconnect from other entities	Disconnect from other entities	Disconnect from other entities	Disconnect from other entities
Release	Free from testbed	Return resource to the pool	Shutdown VNF	Shutdown VNF	Shutdown VNFs	Shutdown VNF
Query	Get connectivity status and measurements	Get logical association status, number of UE connected, measurements	Get connection status	Get connection status	Get connection status, registered users	DL data notification, traffic routing
