detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention provides a call intervention method.

Referring to FIG. 1, FIG. 1 is a schematic flowchart diagram of a first embodiment of a call intervention method according to the present invention.

This embodiment provides a call intervention method, where the call intervention method includes:

Step S10: Upon receiving the call request sent by the call forwarding device, the server determines the user number corresponding to the call request;

In this embodiment, before the step S10, the method includes the following steps: the call forwarding device starts a preset interface, and the preset interface is a WEB interface of the switchboard service, that is, a WEB interface provided to the operator for querying data or call control, when the operator logs in. In the preset interface, the user number is input in the preset interface, or the user number is selected in the preset interface, and the call forwarding device receives a call request triggered by the user based on the user number, Then the call request is transmitted to the server. The server in this embodiment is preferably a web server (Web Server, WS for short), and the server provides a service function of HTTP (Hypertext Transfer Protocol), user login, call number filling, and call control. And the function of the information display interface, the server determines the user number corresponding to the call request when receiving the call request sent by the call forwarding device, and the user number is: the operator is triggered based on the user number A in the preset interface. If the call is requested, the server determines that the user number corresponding to the call request is A.

Step S20: When the number of the call forwarding device is in the same group as the user number, send a call request to the control point CP corresponding to the user number, where the call request is used to call the user number;

Optionally, in order to improve the intelligence of the call intervention, when the number of the call forwarding device is in the same group as the user number, the call intervention method further includes:

In step A, the server sends a query request of the CP corresponding to the user number to the preset CP, where the query request is used to query the CP information of the CP corresponding to the user number;

Step B: The server receives CP information that is fed back by the CP corresponding to the user number based on the query request.

Step C: Determine, according to the received CP information, a CP corresponding to the user number.

In this embodiment, when the number of the call forwarding device is in the same group as the user number, that is, when the operator corresponding to the call forwarding device and the user corresponding to the user number are users in the group, The server obtains a preset CP (Control Point), and the preset CP may be any CP or a CP that is set in advance. In this embodiment, the preset CP is recorded as a CP-R. The default CPs described below are all based on CP-R. After the preset CP, the CP is sent to the preset CP to query the CP (indicated as CP-A) to which the user number A belongs. When the CP-R receives the query request, the CP-R sends the INVITE carrying the query request. The call, that is, the CP-R sends an INVITE request to the CP-A, and the content in the FROM is the service code of the CP where the query A is located. The specific process is as follows: Referring to FIG. 7, the INVITE is sent to the core network through the call distribution server SIPPROXY, and the core network determines that the called process of A needs to be taken, and then the INVITE is sent to SIPPROXY, and the SIPPROXY distributes the INVITE to the CP-A, CP- A receives the INVITE and determines that it is a call to query the CP where A is located. Then CP-A returns the information of its own CP-A to the server, and CP-A releases the call for inquiring CP-A. At this time, CP-R The CP-A sends an ACK (Acknowledgement) confirmation message, and finally the server determines the CP corresponding to the subscriber number, that is, CP-A, according to the received CP information.

When determining the CP corresponding to the user number, the server sends a call request to the CP corresponding to the user number, that is, the server sends a request message for calling the user A to the CP-A, and at this time, the CP- A calling the user number according to the call request, specifically, the manner in which the CP-A calls the user number according to the call request includes: the CP-A first responds to the server with a response message in the call processing, and The server also replies to the call forwarding device with a response message in the call processing, and then the CP-A sends an INVITE request to the call relay device, and the request number is a number corresponding to the call forwarding device, such as H, and if the call forwarding device is called at this time When the corresponding number H picks up the phone, the call forwarding device H returns a response message to the CP-A, and then the CP-A sends an INVITE request to the user number A, and the request number is A.

Optionally, the preset CP may also be a CP corresponding to the user number, that is, the CP-A. If the CP-A receives the query request of the user number A, the query request of the user number A is also distributed through the call. The server SIPPROXY is sent to the core network. The core network determines that it needs to go to the called process of A. Then, the INVITE is sent to SIPPROXY. SIPPROXY distributes the INVITE to CP-A. CP-A receives the INVITE and judges that it is a query A. The CP calls, and the CP-A returns its own CP-A information to the server.

In step S30, if it is detected that the user number is currently in a call state, the call intervention request of the call relay device is sent to the CP corresponding to the user number, and the call intervention request is used for calling the user number. The process intervenes.

In this embodiment, if the user number A is currently in the call state, the CP-A replies to the server with a message that the user number A is in a call state, and the server receives a message that the user number A is in a call state. At the same time, the call forwarding device feeds back a message that the user number A is in a call state, and receives the call intermediation device based on the call intervention request input by the user in the preset area, and then the server sends the call intervention request to the call The CP corresponding to the user number, that is, CP-A, implements a related call intervention function by the CP-A, and the intervention mode includes: inserting, that is, a call joining the user number; and listening, that is, a call listening to the user number Process; replace, that is, replace other user numbers that are talking to the subscriber number.
