The command AT+GTGEO is used to configure the parameters of Geo-Fence. (Geo-Fence is a
virtual perimeter on a geographic area using a location-based service, so that when the geofencing
terminal
enters or exits the area a notification is generated. The notification can contain
information about the location of the terminal and may be sent to the backend server.)
