Description

Technical Field

[0001] The present disclosure relates to the field of communications, and in particular, to an information transmission method and apparatus, and a storage medium. Background Art

[0002] An unmanned aerial vehicle, abbreviated as UAV (Unmanned Aerial Vehicle), is an unpiloted aircraft controlled by a radio remote control device and a self - contained program control device. In fact, UAV is a general term for unpiloted aircraft. From a technical perspective, it can be divided into: unmanned fixed - wing aircraft, unmanned vertical take - off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi - rotor aircraft, unmanned parafoil aircraft, etc.

[0003] With the rapid development of UAV technology, cost reduction, and function improvement, UAVs are increasingly used by ordinary consumers. And the application of UAVs in industries is the real demand for UAVs. Currently, applications in fields such as aerial photography, agriculture, plant protection, micro - self - shooting, express delivery, disaster rescue, observing wild animals, monitoring infectious diseases, mapping, news reporting, power line inspection, disaster relief, film and television shooting, creating romance, etc. have greatly expanded the uses of UAVs themselves. Each country is actively expanding industrial applications and developing UAV technology.

[0004] In order to further expand the application scope of UAVs, the 3rd Generation Partnership Project (3GPP) has approved the establishment of the Enhanced Support for Aerial Vehicles project. The aim is to study and standardize how to enable the cellular network to provide services that meet the requirements for UAVs.

[0005] UAV flight generally has two modes. One is the fixed mode, that is, the operator plans the flight route of the UAV on the controller, and then the UAV can fly according to the planned route, and the controller does not need to control the UAV all the time. The other mode is the dynamic mode, that is, the controller will remotely control the UAV in real - time all the time. For the fixed mode, since the flight route and trajectory of the UAV are fixed, the cellular network can predict which cellular network base stations the UAV will pass by.

[0006] Therefore, how to efficiently report the flight path information of UAVs is an urgent problem to be solved. Further, once the UAV changes its flight mode during flight, for example, from the dynamic mode to the fixed mode, how to efficiently report the flight path information when the flight mode changes is also an urgent problem to be solved.
