Preferred embodiment of the invention

The invention will be further described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 , it is a schematic structural diagram of the system of the present invention. The system includes a PC client and an application server. The terminal is connected to the application server through a core network, and the PC client is used to initiate a multi-party call transfer request. The application server is configured to provide a multi-party call service and a conference service, and includes a multi-party call service module, a conference service module, a pre-processing module, a service platform, and a media server, where the multi-party call service module is configured to provide access and logic of the multi-party call service. Control; used to push the call information of the terminal or the information reported by the service platform to the pre-processing module

The PC client receives the information sent by the PC client through the pre-processing module; is used to notify the PC client through the pre-processing module after the terminal that needs to transfer the conference transfers to the conference; the conference service module is used to create the conference; The call-to-conference request indicates that the service platform transfers the terminal in the multi-party call to the designated conference; the pre-processing module is used for converting the internal message and the standard SIP message between the multi-party call service module and the PC client, and The message is sent to the corresponding module; the service platform is configured to transfer the terminal in the multi-party call to the designated conference according to the instruction of the conference service module.

As shown in FIG. 2, it is a flowchart of the first embodiment of the method. In this embodiment, the PC client is in the conference, and the member of the conference includes the PC client and the UE1, and specifically includes the following steps: Step 201: UE2 Call the service number of the PC client to trigger the multiparty call service module.

When the PC client initiates a call as a calling party, it can bind a soft terminal or a hard terminal. Each PC client login name is assigned a service number. The terminal as the calling party can dial the service number of the PC client, that is, the PC client is called at this time; whether the PC client initiates the call as the calling party, or The called party accepts the call, and the call information is pushed by the multi-party call service module.

The call information pushed by the multi-party call service module to the PC client includes: the number information of the terminal, Call ID in the service platform, call leg ID in the service platform, and call status information.

For example, the PC client as the called party will trigger the multi-party call service module, and the multi-party call module will push the number information of the calling party of the call to the PC client, the call instance ID in the service platform, and the call in the service platform. Information such as logical leg ID, call status information, and so on.

Step 202: The multi-party call service module reports the call information of the UE2 to the PC client through the pre-processing module.

The foregoing call information includes: number information, a call instance ID of the UE2 in the service platform, a call logical leg ID of the UE2 in the service platform, and call state information of the UE2.

Step 203: After receiving the information, the PC client allows the UE2 to join the current conference, save the call information of the UE2, and send a multi-party call transfer conference request to the service platform.

The multi-party call forwarding conference request is a standard SIP Refer message, and the message body carries the call logical leg ID of the UE2 in the service platform; other messages, such as the number information of the UE2 and the call instance ID of the UE2 in the service platform, may be It is obtained by querying the call logic leg ID of the UE2 in the service platform, so it may or may not be carried;

In this step, if the terminal that the PC client rejects the incoming call joins, the rejected SIP message is sent to the pre-processing module, and the pre-processing module converts the received SIP message into an internal message and sends the message to the multi-party call module, and the multi-party call module receives the message. Release this call later.

Step 204: The service platform converts the received SIP message into an internal message and reports it to the conference service module.

Step 205: After receiving the message, the conference service module learns that the UE2 is a terminal that transfers to the conference according to the value of the call leg ID, that is, the service platform is added to the UE2 to join the current conference;

Step 206: The service platform executes the indication, and returns a join success message to the conference service module after the success;

Step 207: The conference service module sends a processing completion message to the service platform.

Step 208: The service platform sends the UE2 to release the message to the multi-party service module, and notifies the multi-party call service module UE2 to transfer the conference successfully;

Step 209: The multiparty call service module notifies UE2 that the joining conference is successful.

As shown in FIG. 3, it is a flowchart of Embodiment 2 of the method according to the present invention; in this embodiment, a PC guest The UE is in a multi-party call, and UE1 and UE2 are involved in the multi-party call. When UE1 and UE2 call the service number of the PC client, the call information is sent by the multi-party call module to the PC client through the pre-processing module, that is, the PC. The call message of the UE1 and the UE2 is already stored in the client. At this time, the PC client, the UE1, and the UE2 all think of the communication in the conference, and then the method is transferred to the conference by the method, which includes the following steps:

Step 301: The PC client sends a create conference request to the service platform.

Step 302: The service platform converts the received request into an internal message and sends the request to the conference service module.

Step 303: The conference service module creates an instant conference;

Step 304: The conference service module reports the platform module to create an instant conference success message. Step 305: The service platform returns a session success message to the PC client.

Step 306: The PC client sends a multi-party call transfer request to the service platform one by one, and transfers the multi-party call members to the conference one by one;

Step 307: The service platform converts the received request into an internal message and sends the message to the conference service module. Step 308: The conference service module instructs the service platform to add the corresponding terminal to the conference. Step 309: The service platform executes the indication, and returns to join after the success. Success message to the conference service module;

Step 310: The conference service module sends a processed completion message to the service platform.

Step 311: The service platform sends a corresponding terminal to release the message to the multi-party call module, and informs the corresponding terminal of the multi-party call module that the terminal has been added to the conference;

Step 312: The multi-party calling module notifies the corresponding terminal of the PC client to leave the message through the pre-processing module, and informs the PC client that the corresponding terminal leaves the current multi-party call.

Industrial applicability

The invention realizes user accessibility from a multi-party call to a conference or converts a multi-party call into a conference call based on the PC client, improves the user experience, improves the communication efficiency of the user, and improves the user's use. The PC client communicates enthusiasm and ultimately increases the operator's revenue.
