1. A method for mitigating power failure in a wireless communication network provided by at least one base station, said at least one base station comprising a primary power supply and a secondary power supply, the method comprising:
(i) receiving a first signal indicating that the primary power supply of said at least one base station has failed or is predicted to fail, or (ii) failing to receive a second signal indicating that the base station is operating normally;
based at least on determining that the primary power supply of said at least one base station has failed or is predicted to fail, transmitting a signal to an unmanned aerial device (UAD) to trigger the UAD to travel to said at least one base station to charge the secondary power supply of said at least one base station, wherein
the secondary power supply of said at least one base station comprises one or more batteries,
charging the secondary power supply of said at least one base station comprises charging said one or more batteries,
that the primary power supply of said at least one base station has failed or is predicted to fail is determined based on receiving the first signal or failing to receive the second signal, and
the method further comprises:
obtaining an indication indicating that the UAD is unable to charge said one or more batteries serving as the secondary power supply of said at least one base station; and
based on obtaining the indication, transmitting a signal to another UAD to trigger said another UAD to travel to said at least one base station to charge said one or more batteries serving as the secondary power supply of said at least one base station.
