This clause defines AT commands that a TE may use to control MT supporting UAS services. The MT supporting UAS supports UUAA procedure and C2 authorization procedure as defined in TS 24.501 for 5GS and in TS 24.301 for EPS. A comprehensive set of UAS specific commands is defined to provide the flexibility needed by the more complex MT. The commands are designed to be expandable to accommodate new UAS feature options and interface protocols, merely by defining new values for many of the parameters. The commands use the extended information and error message capabilities described in this specification. The +CUUAAPT command requests the UE to transport the UUAA parameters to the network and to report the UUAA parameters received from the network as defined in TS 24.501 for 5GS and in TS 24.301 for EPS. The +CC2APT command requests the UE to transport the C2 authorization parameters to the network and to report the C2 authorization parameters received from the network as defined in TS 24.501 for 5GS and in TS 24.301 for EPS
