Communication quality detection method, apparatus and device

A communication quality detection method, apparatus and device. The method comprises: after a communication quality detection apparatus detects a communication quality parameter between an aerial vehicle and a control terminal, the communication quality detection apparatus can determine a cause for a communication quality change occurring between the aerial vehicle and the control terminal according to a fact that whether the communication quality parameter satisfies a preset threshold condition, and generate indication information comprising the cause, so that the communication quality between the aerial vehicle and the control terminal can accurately detected. Further, by outputting the indication information, a user can be helped to adjust operations, which helps to improve communication performance to some extent, and improve flight experience of the user.
