Method and system for monitoring crank call

The invention discloses a system and a method for monitoring a crank call. The method comprises the following steps of: monitoring real-time call detail record (CDR) data transmitted through a Socket interface by a number seven signaling monitoring system on the basis of monitoring of internet links, long-distance links and intranet important mobile switching center (MSC) links by using the system; analyzing the number of a suspected crank call according to a multiple suspected crank call filtering mechanism and corresponding filtering parameters; comparing the suspected crank call with a white list, and if the suspected crank call exists in the white list, deleting the number of the suspected call from a database; submitting the number of the suspected crank call to a crank call platform if the suspected crank call does not exist in the white list; and performing dial testing verification on the number on the crank call platform, judging whether the suspected crank call is the crank call or not according to conversation contents, determining the home location of the number if the suspected crank call is confirmed to be the crank call, and transmitting an intercept instruction to a number home location network management center.
