[0067] The detection condition includes the calling party, the incoming trunk, the calling number, the called office, the outgoing trunk, and / or the called number corresponding to the calling call information. Wherein, the calling party information is compared with all the parameters in the detection condition one by one, if it matches one of the parameters, then continue to compare whether other parameters matching the parameter match, if all the parameters match match, then detect that the call is a normal call, if not consistent with one of the parameters, then detect that the call is a suspicious call.

[0068] For example, the call comes from trunk number 5, the connected office of trunk number 5 is Guangzhou International Bureau, and the calling number is 0008620XXXXXXXX. However, the caller of the No. 5 trunk connected with the Guangzhou International Bureau in the existing network is generally 000190XXXX, so the call is determined to be a suspected call.

[0071] The detection condition is a threshold value of the number of calling times within a specified time. Wherein, it is judged whether the calling call information is greater than or equal to the threshold value of the number of calling calls within a specified time, if yes, then detecting that the call is a suspected call; otherwise, detecting that the call is a normal call.

no. 3 example

[0073] The detection condition is the stored suspected call information. Wherein, it is judged whether the call information of the calling party is the same as the stored suspected call information, if yes, detect that the call is a suspected call, otherwise, detect that the call is a normal call. The suspected call information mentioned here includes the calling party, incoming trunk, calling number, called office, outgoing trunk, and / or called number corresponding to the calling call information.

[0074] In this embodiment, the suspected call information can be stored in the suspected call number table, and the stored suspected call information can be the information extracted after the suspected call has been confirmed in each of the above embodiments, such as the calling party number, Or, the suspected call that has been confirmed in the prior art is stored in the suspected call number table. At this time, once the subsequent call is matched, it can also be judged as a s...

Abstract

The invention discloses a calling detection method, device and system. The method comprises the following steps: a switch receives main calling information, compares the main calling information with a set detection condition, and detects calling according to a comparison result. The switch is utilized to carry out detection. Therefore, a lot of network relay resources do not need to be occupied, and then waste of network resources is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a call detection method, equipment and system. Background technique [0002] In the existing call detection method, after the switchboard receives the call, all the calls are sent to the interception platform for processing, the interception platform connects the signaling process of the call in series, and sends the call back to the switching center for subsequent processing. [0003] When the called party picks up the phone, the interception platform recognizes that the call has been connected through signaling, and then modifies the call signaling, changing the called terminal address of the calling signaling to the platform address, and changing the calling terminal address of the called signaling to Change it to the platform address, connect to the traffic process in series for traffic monitoring, and perform alarm or interception processing when a user key is monitored. ...
