The disclosure relates to a relay method, a relay device and a relay terminal. The method includes the following steps: obtaining the current height of the relay terminal; judging whether the currentheight is within a preset height range; and if the current height is within the preset height range, sending determination information to at least two communication terminals associated with the relayterminal to facilitate the communication between the at least two communication terminals. According to the technical scheme, when the relay terminal relays the communication between the at least twocommunication terminals associated with the relay terminal, the communication range between the at least two communication terminals can be increased by adjusting the height of the relay terminal, the influence of obstacles existing between the communication terminals on the communication between the communication terminals can be avoided, and the practicability of the communication terminals canbe improved.
