The call between the calling terminal and the called terminal; the MSC is used to control and manage the two parties in the call, that is, the calling terminal and the called terminal.

It should be noted that the harassing call interception device is serially connected between MSCs, so that the harassing call interception device can collect call information between the calling terminal and the called terminal via the MSC in real time.

Fig. 2 is a schematic flow chart of a method for intercepting harassing calls provided by an embodiment of the present invention. The method is applied to a harassing call intercepting system, including:

S201: The harassing call interception device collects call information between the calling terminal and the called terminal in real time;

It should be noted that the harassing call interception device can collect the call information between the two parties in the call in real time, that is, between the calling terminal and the called terminal, unlike the system in the prior art that only judges the call content of the suspected harassing phone number. Unable to handle non-suspected harassing calls, thus expanding the interception scope of harassing calls.

Exemplarily, the basis for the harassing call interception device to collect call information between the calling terminal and the called terminal in real time is that the harassing call interception device collects the information between the calling terminal and the called terminal through the MSC according to the protocol related to the call. Judgment; when the information passing through the MSC between the calling terminal and the called terminal conforms to the protocol related to the call, the harassment call interception device determines that the information passing through the MSC between the calling terminal and the called terminal is the one between the calling terminal and the called terminal. call information.

It should be noted that the call-related protocol information includes SS7 protocol, bearer independent call control (BICC, Bearer Independent Call Control protocol) protocol, session initiation protocol (SIP, Session Initiation Protocol) protocol and real-time transport protocol ( RTP, Real-time Transport Protocol) protocol, etc., if the harassing call interception device judges that the information passed through the MSC between the calling terminal and the called terminal conforms to the protocol related to the call, it means that the calling terminal and the called terminal are using this protocol for communication. Therefore, it can be determined that the information passing through the MSC between the calling terminal and the called terminal is the call information between the calling terminal and the called terminal; The information does not conform to the protocol related to the call, such as the Simple Network Management Protocol (SNMP, Simple Network Management Protocol) protocol, the Internet Control Message Protocol (ICMP, Internet Control Message Protocol) protocol, etc., it means that the communication between the calling terminal and the called terminal If there is no call but other operations are performed, the information passing through the MSC between the calling terminal and the called terminal will not be processed.

S203: The harassing call interception device matches the text information with the harassing call text information in the text library; if they cannot be matched, then S204: Allow the calling terminal to continue talking with the called terminal; if they match, then S205: Intercept the calling terminal from communicating with the called terminal A call between called terminals.

It should be noted that the text library stores the text information of harassing calls. If the text information can match the text information of harassing calls stored in the text library, it means that the call information between the calling terminal and the called terminal contains advertising, product promotion, Abnormal call content such as threatening calls, so the call is intercepted as a nuisance call.

Understandably, the accuracy of the method for intercepting harassing calls proposed in the embodiments of the present invention is related to the text information of harassing calls stored in the text library.
