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
Description
This command allows the MT to provide no-transmit zone assistance information as specified in
TS 24.501 for 5GS and in
TS 24.301 for EPS. Refer
clause 9.2 for possible
<err> values.
Defined values
<geographical_area_id>
integer type. Identifies the geographic area where the no-transmit zone is valid.
<number_of_polygon_points>
integer type. Indicates the number of entries for latitude and longitude describing the points of the poygon representing the geographical area where the restrictions apply. Minimum value is 3 and maximum value is 15 according to
clause 7.3.4 of TS 23.032.
<latitude>
integer type; contains latitude value which is coded according to
clause 6.1 of TS 23.032. To represent a n-point polygon, this value is used n times.
<longitude>
integer type; contains longitude value which is coded according to
clause 6.1 of TS 23.032. To represent a n-point polygon, this value is used n times.
<ceiling_altitude>
integer type; contains the altitude ceiling up to which the restrictions apply, which is coded according to
clause 6.3 of TS 23.032.
<floor_altitude>
integer type; contains the altitude floor up to which the restrictions apply, which is coded according to
clause 6.3 of TS 23.032.
<number_of_restricted_freq_bands>
integer type. Indicates the number of entries for restricted frequency bands.
<rat_type>
integer type; indicates with the RAT type which the UE shall apply NTZ assistance information.
0
E-UTRAN
1
NG-RAN
<restricted_freq_band>
<number_of_time_restrictions>
integer type; Indicates the number of entries for restricted time period.
<start_time>
string type. This parameter contains the start time of the restricted time period for no-transmit zone, represented by the number of seconds since 00:00:00 on 1 January 1970 UTC and is encoded as the 64-bit NTP timestamp format defined in
RFC 5905, where binary encoding of the integer part is in the first 32 bits and binary encoding of the fraction part in the last 32 bits.
<end_time>
string type. This parameter contains the end time of the restricted time period for the no-transmit zone, represented by the number of seconds since 00:00:00 on 1 January 1970 UTC and is encoded as the 64-bit NTP timestamp format defined in
RFC 5905, where binary encoding of the integer part is in the first 32 bits and binary encoding of the fraction part in the last 32 bits.
