The method of the embodiment of the invention comprises three steps: a verification triggering step, a password verification step and a call forwarding step. Referring to fig. 1, a server receives a call request initiated by a calling terminal to a called terminal, and forwards password voice prompt information preset by the called terminal to the calling terminal; then, the server receives the password reply information sent by the calling terminal, analyzes the password reply information and compares the password reply information with a password answer preset by the called terminal to obtain a password verification result; and then, forwarding the call request to the called terminal according to the password verification result.
In the embodiment of the invention, a calling terminal calls a called terminal, a call request passes through a server, the server firstly detects whether the called terminal opens a password verification service, and if the called terminal opens the password verification service, a password verification process is triggered; otherwise, executing normal number segment blacklist verification or directly forwarding the call request to the called terminal. The password authentication process is as follows: the server side takes out the preset password voice prompt information of the called terminal and plays the calling terminal; the user of the calling terminal performs related operations according to the content of the password voice prompt information, and the calling terminal sends password reply information to the server; and the server receives the password reply information, analyzes and processes the password reply information, compares the password reply information with a password answer preset by the called terminal, and judges whether the password is verified. And for the call passing the password verification, the server forwards the call request to the called terminal.
In the embodiment of the invention, the preset of the called terminal password voice prompt information and the password answer can be set by connecting with an OSS system of an operator through any one of a WeChat public number, an operator APP or a short message mode.
In the embodiment of the invention, the password reply information is key information or voice reply information. Generally, if a user only wants to simply prevent telephone harassment at the beginning of a common recording, the user can simply request a caller to input a certain key (1-9, #) or input a simple four-rule operation result; if the user needs high privacy and only allows people who know the password to call in, the caller can be required to input a multi-digit password through keys or speak the password through voice, and the media resource server extracts features through voice recognition to judge whether the password is allowed to pass or not. The key is mainly sent to the server through three transmission modes: carrying SIP protocol INFO message; RFC2833 protocol mode; 3. in-band dual tone multi-frequency mode. For the first mode, the server side directly obtains a key value from the INFO message and compares the key value with a password answer preset by the called terminal; for the 2 nd and 3 rd modes, the media resource server needs to identify the mode and then compares the mode with the password answer preset by the called terminal.
The system of an embodiment of the present invention, referring to fig. 2, includes: a terminal module 100 and a service end module 200; for ease of understanding, fig. 2 shows 2 terminal modules 100, one of which is the calling terminal module and the other of which is the called terminal module. It should be understood that in embodiments of the present invention, multiple terminal modules may be included; the same terminal module can be used as a calling terminal module and a called terminal module. The terminal module 100 is configured to initiate or receive a call request to perform a call. The server module 200 is configured to perform password verification on the call request.
In the system of the embodiment of the present invention, the server module 200 further includes: a media resource module 210, a call control module 220, and a password authentication module 240, see fig. 2. The call control module 220 is mainly configured to detect whether a called terminal module activates a password authentication service, trigger password authentication, and forward the call request to the called terminal module according to a password authentication result; in addition, the call control module 220 is also responsible for extracting the key information carried in the SIP protocol INFO message. The media resource module 210 is configured to play password voice prompt information preset by the called terminal module to the calling terminal module, perform voice recognition on the voice reply information, and extract corresponding feature information; in addition, the media resource module 210 is also configured to identify RFC2833 and key information in the dual tone multi-frequency mode. And the password verification module 240 is configured to compare the identified password reply information of the calling terminal module with a password answer preset by the called terminal module, and obtain a password verification result.
In the system of the embodiment of the present invention, the server module 200 further includes: and a password setting module 230, configured to activate a password authentication service, and set password voice prompt information and a password answer. The settable password voice prompt information comprises the following contents: for example, "please press the X key", "please input 1+1 equal to several on the keyboard", "please speak the connector number", etc. The password voice prompt information and the password answer are preset, and the password voice prompt information and the password answer can be set by connecting with an OSS (open service system) of an operator through any one of a WeChat public number, an operator APP (application) or a short message mode, and the password voice prompt information and the password answer are opened.
Fig. 3 shows the interaction of modules in an embodiment of the present invention during a call process. In fig. 3, UE a is a terminal module as a calling party, and UE B is a terminal module as a called party. The media resource module 210 in the server module 200 is disposed on an MRS (i.e., a resource media server), and the call control module 230 is disposed on an S-CSCF (i.e., a call control function) of an authentication AS (an authentication application server). UE A sends a call request, and the call request is received by the verification AS to trigger verification service. And when the UE B opens the password verification service, the verification AS sends a signal in the process of conversation to the UE A, and the MRS plays the password voice prompt information preset by the UE B to the UE A. If the UE A sends a plurality of SIP protocol INFO information according to the operation of a user, and the INFO information carries key value information, the verification AS extracts the key information and compares the key information with a password answer preset by a called terminal module UE B; if UE A sends some voice reply information according to user's operation, then the voice reply information is sent to MRS, MRS will identify and verify the voice reply information through AI voice recognition, obtain the verification result. And the verification AS judges whether the verification is passed according to the verification information sent by the verification AS or the MRS, and forwards the call request to the UE B after the verification is passed. And the UE B receives the call request and returns a message code in the ringing to the UE A through the verification AS. If the user of UE B connects the call, the verification AS transfers the successful conversation information transmitted by UE B to UE A; UE A receives the successful information of the session and sends the successful information to UE B through verification AS; after receiving the acknowledgement message of the UE a, the UE B establishes a call connection between the calling terminal module UE a and the called terminal module UE B.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
