1. A method for cellular network signal measurement, comprising:
acquiring at least one set of measurement data collected during a flight of an unmanned aerial vehicle (UAV), each of the at least one set of measurement data comprising a base station identifier and a signal quality parameter and the base station identifier being an identifier of a base station for residing during collection of the measurement data; and
sending the at least one set of measurement data to a base station, wherein the base station is the same as or different from the base station for residing during collection of the measurement data, and the at least one set of measurement data is used for determining whether the base station has a coverage vulnerability,
wherein determining whether the base station has the coverage vulnerability comprises one of:
when a flight path of the UAV is formed by connecting multiple coordinate points within a coverage area of a side lobe of the base station in series, determining, by the base station from the at least one set of measurement data, measurement data containing base station identifiers different from a base station identifier of the base station; and in response to determining that an amount of the measurement data containing the base station identifiers different from the base station identifier of the base station exceeds a set proportion, determining that the base station has the coverage vulnerability; or
when each of the at least one set of measurement data further comprises a flight altitude and a geographical position, determining, by the base station, measurement data in a coverage area of a side lobe of the base station according to the flight altitude and the geographical position, and in response to determining that a base station identifier in the measurement data is different from a base station identifier of the base station, determining that the coverage area of the base station has the coverage vulnerability.
