Method and system for monitoring crank call

Abstract

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. According to the system and the method, the intercept rate of the crank call is increased, and the interference of the crank call is reduced.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to the technical field of No. 7 signaling of the mobile communication network. Background technique [0002] In real life, incoming harassing calls are often encountered. In order to avoid the interference of harassing calls, in general, the harassing phone number filtering and discrimination mechanism should include the following discrimination mechanism: [0003] Filtering of call loss results: According to the call loss item parameters configured on the application platform, all call records are filtered once based on the call loss results; [0004] Ringing duration filtering: according to the ringing duration parameters configured on the application platform, secondary filtering is performed on the call records filtered by the call loss results; [0005] Call frequency filtering: according to the call frequency threshold of the calling number configured on the applicat...

Problems solved by technology

[0008] However, in the existing technology, for the suspected blacklist of harassing calls, after comparing with the blacklist and whitelist, if it is not in the blacklist or whitelist, and the automatic approval mode is not activated, or the call frequency does not reach the automatic approval even though it is activated Threshold, unable to take effective measures to review and control it, so that it is impossible to determine and intercept the interference caused by harassing calls
