Abstract

The invention provides a crank call interception method and device. The crank call interception method comprises the following steps: acquiring a calling number which is calling at present and the ringing time of the calling number after the crank call interception mode of a communication terminal is started; if the ringing time of the calling number is smaller than a first preset threshold and the calling number is not a number of the number directory of the communication terminal, directly intercepting the calling number; if the ringing time of the calling number is larger than or equal to the first preset threshold and the calling number is not a number of the number directory of the communication terminal, prolonging the ringing time of the calling number, uploading the calling number to a cloud server, and directly intercepting the calling number when the cloud server confirms that the calling number is a crank call. Compared with a method that crank call numbers are manually added into call firewalls or blacklists, the crank call interception method is relatively accurate in identifying crank calls, and a user is effectively prevented from harassment of malicious crank calls.
