摘要： A method performed in a network node is provided for alerting about failure of an unmanned aerial vehicle. The method comprises receiving a failure report from an unmanned aerial vehicle, obtaining an estimated crash point for the unmanned aerial vehicle, and sending, based on the obtained estimated crash point, warning signals to communication devices residing within a defined area. Methods in an unmanned aerial vehicle and in a network entity, and a network node, unmanned aerial vehicle, network entity, computer programs and computer program products are also provided.

摘要： A method (50) of route directing performed in an unmanned aerial vehicle (8a) is provided. The unmanned aerial vehicle (8a) comprises a communication module (9a) for wireless communication with an access node (2a, 2b) of a communications system (1). The method (50) comprises receiving (51), from a network entity (11), warning signaling about a restricted area, and withdrawing (52) from the restricted area in response to receiving the warning signaling. A method (20) in a network entity (11) is also provided, as well as an unmanned aerial vehicle (8a), a network entity (11), computer programs and computer program products.
