Abstract: The methods and systems for improving communication distribution. In particular, the methods and systems for improving communication distribution in environments where there is both the need for end-user specific data (e.g., customized content) and/or data storage constraints. For example, in order to address the security/privacy concerns during communication distribution, the methods and systems use a novel architecture that limits the amount of data that must be stored. Specifically, the system does not require permanent storage of communications featuring end-user specific data prior to the distribution of these communications. Accordingly, the storage requirements are greatly diminished, and privacy/security concerns are avoided.

Abstract: The present disclosure provides a flight processing method applied to a control device of an unmanned aerial vehicle (UAV). The method includes obtaining a clearance permission file of a target flight restriction area from a server, the clearance permission file being generated by the server in response to flight clearance application information of the flight restriction removal conditions obtained from a smart terminal; and removing flight restrictions of the UAV in the target flight restriction area based on the clearance permission file.

Abstract: A method for controlling flight of an unmanned aerial vehicle, includes receiving a data file indicating flight restriction level and range of an airport area in an airport generated according to a risk level of the airport, parsing the data file to obtain the flight restriction level and the range of the airport area, and controlling the unmanned aerial vehicle to execute a flight restriction strategy according to the flight restriction level and the range of the airport area.

Abstract: A method for planning a restricted fly zone, a flight control method, a smart terminal, and a control device are provided. The method of planning a restricted fly zone includes processing a map according to a pre-configured meshing scheme, tagging designated meshes in the map according to input information, and planning the restricted fly zone according to map areas associated with the tagged meshes. Areas beyond the restricted fly zone are a fly zone. This allows the restricted fly zone to be determined straightforward and quickly to facilitate subsequent flight control.
