Research has found that with the development of globalization and mobile communication technology, there is an increasing demand for enabling efficient and stable multiparty calls.

Currently, the multi-party call technology on the market often relies on telephone networks or primary network protocols, which have many limitations in terms of functionality and performance. For example, early multiparty call systems often cannot support high definition audio and video, and the user experience is poor; at the same time, these systems also lack flexibility and cannot be dynamically adjusted according to the number and quality requirements of call participants. Therefore, in multiparty calls, the multimedia data streams from different participants need to be processed correctly to ensure that each participant has a good call experience. On the market, based on OTT multi-person video call service, a Web standard protocol (WebRTC API, SRTP, ICE) is used to establish a call connection, requiring a user to register a personal account number and join a video call through a browser, or a corresponding client/applet application; the scheme is based on VoLTE video call provided by an operator, call connection is established by using SIP and SDP protocols, terminal side transformation is not needed to support the reception of multiple paths of audio and video streams, and a user dials a call number through a dial plate to join in the multiparty video call.

Based on the above-mentioned study, the present disclosure provides a multiparty call processing method, first, by detecting a call access request of a first call participant, identifying a call sign of a multiparty call room carried in the call access request; secondly, controlling the first call participant to access to a multiparty call room based on the call sign; secondly, receiving the multimedia data stream of each first call participant; the multimedia data stream is an audio and/or video stream acquired by the user equipment after each first call participant accesses the multi-party call room; and finally, mixing the multimedia data streams of all the first call participants in the same multiparty call room to obtain a first data stream, and sending the first data stream to all the first call participants in the multiparty call room through an edge node call forwarding platform.

In the above embodiment, by detecting the call access request of the first call participant, determining the call forwarding number, and controlling the access of the first call participant by using the call forwarding number, the first call participant can be quickly and accurately accessed into the multi-party call room, and the flexibility and efficiency of call control are enhanced. The mixed first data stream is sent through the call sign transferring platform in the edge node, so that the delay of data transmission can be reduced, and the conversation quality can be improved. Therefore, the method provided by the embodiment of the disclosure improves the efficiency of call access, reduces the waiting time, improves the user experience, and ensures the call quality and the stability of the system.

For the sake of understanding the present embodiment, first, a detailed description will be given of a multiparty call processing method disclosed in an embodiment of the present disclosure, where an execution main body of the multiparty call processing method provided in the embodiment of the present disclosure is generally an electronic device with a certain computing capability. In some possible implementations, the multiparty call processing method may be implemented by a processor calling computer readable instructions stored in a memory.

Referring to fig. 1, a flowchart of a multiparty call processing method according to an embodiment of the present disclosure is shown, where the method includes steps S201 to S204, applied to an application server, where:

s201, detecting a call access request of a first call participant, and identifying a call forwarding number of a multiparty call room carried in the call access request.

In the embodiment of the present application, first, the application server may detect a call access request of a first call participant, where a method for detecting a call access request will be described in the following embodiments. After detecting the call access request, the call access request can be identified to determine the call forwarding number of the multiparty call room carried in the call access request.

Here, the call access request is forwarded to the application server by the call sign forwarding platform of the edge node, where the call access request generally includes the call sign of the multiparty call room to which the first call participant wants to join. At this time, the application server can identify the call access request, so as to obtain the call sign of the multiparty call room carried in the call access request.

Here, the multi-party call room is created by the call initiator, and the first call participant is one or more participants who want to access the multi-party call room except for the call initiator.

S202, controlling the first call participant to access to the multi-party call room based on the call sign.

In the embodiment of the disclosure, after a call initiator initiates creation of a multi-party call room, a call sign forwarding platform can generate a corresponding call sign for the multi-party call room, and establish a communication switching relationship between the call sign and the room sign of the multi-party call room; the call forwarding platform may then send the communication-diversion relationship to the application server.

After determining the call forwarding number based on the detected call access request, the application server may determine a room number of a multiparty call room accessed to the call forwarding number according to the communication forwarding relationship. The application server may then access the first call participant to the multi-party call room.

S203, receiving the multimedia data stream of each first call participant; the multimedia data stream is an audio and/or video stream collected by the user equipment after each first call participant accesses the multi-party call room.

In an embodiment of the present disclosure, the multiparty call room may include a plurality of first call participants, for example, may include 2 to 9 first call participants, and here, the number of the first call participants is not particularly limited so as to be able to be implemented.

Here, the multiparty call room may be a video call room or an audio call room. Under the condition that the multiparty call room is a video call room, the user equipment corresponding to each first call participant can collect the audio stream and the video stream of each first call participant, so as to obtain the multimedia data stream of the first call participant. Under the condition that the multiparty call room is an audio call room, the user equipment corresponding to each first call participant can collect the audio stream of each first call participant, so as to obtain the multimedia data stream of the first call participant.

In the embodiment of the application, in the case that the multiparty call room is a video call room, the first call participant may choose to close the camera before entering the video call room, and at this time, the user equipment may not collect the video stream of the first call participant. In addition, the first call participant may choose to close the camera after entering the video call room, and the application server notifies the user device to stop collecting the video stream of the first call participant after detecting the camera closing instruction.

S204, mixing the multimedia data streams of all the first call participants in the same multiparty call room to obtain a first data stream, and sending the first data stream to all the first call participants in the multiparty call room through the call sign transferring platform in the edge node.

In an embodiment of the disclosure, the multimedia data streams of the first call participants may be mixed by a multipoint control unit (MultiPoint Control Unit, MCU) architecture model created by a media service unit in the application server, and the mixed first data streams are obtained.

Here, the MCU may be configured to mix the multimedia data streams of the first call participants according to the acquisition time of each multimedia data stream, and mix the multimedia data streams to obtain the first data stream.

Here, the specific method for the control unit architecture model to mix the multimedia data streams of each first call participant is as follows:

First, the multimedia data streams of the respective first call participants may be input into the control unit architecture model. Secondly, the multimedia data stream of each first call participant can be decoded through the control unit architecture model to obtain a first intermediate data stream of each first call participant. And secondly, rescaling the first intermediate data stream through the control unit architecture model to obtain a second intermediate data stream of each first call participant. Finally, the second intermediate data streams of the first call participants can be mixed through the control unit architecture model to obtain first data streams.

In an alternative embodiment, before receiving the call access request of the first call participant, the method further comprises the steps of:

Firstly, receiving a call creation request of a call initiator forwarded by a call sign forwarding platform, and creating a multiparty call room;

Then, sending a generation request to a call sign transferring platform; the generation request is a request for requesting the call forwarding platform to generate a call forwarding of the multiparty call room;

And finally, acquiring a communication switching relation between the call forwarding number of the multiparty call room fed back by the call forwarding platform and the multiparty call room.

In the embodiment of the disclosure, a call initiator may send a call creation request to a service operation management platform through a call sign forwarding platform. After receiving a call creation request of a call initiator, the service operation management platform creates a multiparty call room for the call initiator and sends a generation request to a call sign transferring platform; wherein the generation request carries the room number of the created multiparty call room.

After receiving the generation request, the call forwarding platform can generate a call forwarding number of the multi-party call room through a call forwarding number distribution system in the call forwarding platform, and bind the room number of the multi-party call room with the call forwarding number. After binding is completed, the communication transfer relationship between the call forwarding number of the multiparty call room and the multiparty call room can be obtained.

Here, after the communication diversion relation between the call sign of the multiparty call room and the multiparty call room is obtained, the communication diversion relation may be transmitted to the application server.

In an embodiment of the present disclosure, a call initiator may send a call creation request to a service operation management platform. The call creation request can be generated by filling in a template provided by the service operation management platform, and can be submitted by dialing a unified service number of the service operation management platform through the mobile terminal equipment.

In the above embodiment, before receiving the call access request, the multiparty call room is created and the call sign is acquired, so that smooth creation and access management of the call are ensured, and the organization and scheduling capability of the system is improved.

Several ways of detecting a call access request by a first call participant will be described in detail below.

Mode one:

in this manner one, the call initiator may invite the first call participant to access by using a group call invite method, in which case, detecting the call access request of the first call participant specifically includes the following procedures:

After a call forwarding relation between a call forwarding number of a multiparty call room fed back by a call forwarding platform and the multiparty call room is acquired, receiving call numbers of a plurality of first call participants input by a call initiator on a call interface of the multiparty call room; simultaneously sending a first dialing request to the calling number of each first call participant; the first dialing request carries a call forwarding number of the multiparty call room.

Here, after entering the multiparty call room, the call initiator may input a plurality of call numbers of the first call participants in a call interface (also referred to as a group call interface) provided by the service operation management platform, and click a "one-click call" button. The application server transmits a first dialing request to the calling number of each first call participant at the same time after detecting the trigger operation of the one-key call button.

The calling number of the first call participant may be an international mobile equipment identity (International Mobile Equipment Identity, IMEI) or an international mobile subscriber identity (International Mobile Subscriber Identification Number, IMSI) of the first call participant.

If the first call participant answers the first dialing request, determining that the call access request of the first call participant is detected.

In an embodiment of the present disclosure, when a first call participant receives a first dialing request and performs a listening operation, it is determined that a call access request of the first call participant is detected, and the first call participant is accessed into a multi-party call room.

In the above embodiment, the system can conveniently receive the call numbers of the plurality of first call participants input by the call initiator after acquiring the call forwarding number, and send a call request to them. This centralized call control makes it more efficient to add new first call participants.

Mode two:

In the second mode, the first call participant can access the multiparty call room in an active dialing mode.

In this case, detecting a call access request of the first call participant specifically includes the steps of:

In an embodiment of the present disclosure, after creating the multiparty call room, the call participant may send the call number of the first call participant to the application server through the call sign forwarding platform. And then, the application server can send the call forwarding number of the multiparty call room to the first call participant through the call forwarding platform.

If a call request of the first call participant to the turn call sign is detected, it is determined that a call access request of the first call participant is detected.

In the above embodiment, the system identifies the call access request actively initiated by the first call participant by detecting the answering operation, so that the judging flow is simplified, and the processing speed and the response time are improved.

Mode three:

in the third mode, the call initiator may invite the first call participant to access in a mode of inviting in a call, in which case, detecting the call access request of the first call participant specifically includes the following procedures:

Before controlling a first call participant to access a multi-party call room based on a call forwarding number, responding to a dialing operation of a second call participant on the first call participant, and initiating a second dialing request to a call number of the first call participant; the second call participant is a participant which is accessed to the multiparty call room before the first call participant, and the second dialing request carries a call number of the multiparty call room.

If the first call participant answers the second dialing request, determining that the call access request of the first call participant is detected.

In an embodiment of the present disclosure, the second call participant is a participant that accesses the multi-party call room before the first call participant. Here, the second call participant invites the first call participant to join the multiparty call room through the handset number. For example, the second call participant may input the call number of the first call participant in the call interface of the multiparty call room, and after detecting a trigger operation of a "call" button in the call interface of the multiparty call room, determine that a dialing operation of the first call participant by the second call participant is detected. At this point, a second dialing request may be initiated to the calling number of the first call participant.

And when detecting the answering operation of the first call participant to the second dialing request, determining that the call access request of the first call participant is detected.

In the above embodiment, all the parties in the multiparty call can invite new parties to join through the mobile phone number of the other party in the multiparty call process, so that the multiparty call access mechanism can continuously process the joining of a plurality of second call participants, and the expansibility of the call is enhanced.

In an alternative embodiment, in the case that the application server is a device disposed outside an IMS (IP multimedia system, IP Multimedia Subsystem) network, the above-mentioned receiving the multimedia data stream of each first call participant includes the following steps:

Receiving multimedia data streams of all first call participants sent by a call sign transferring platform; after a first call participant accesses a multiparty call room, uploading a multimedia data stream to a call sign forwarding platform;

The above-mentioned sending of the target data to each first call participant in the multiparty call room comprises the following steps:

and sending target data to each first call participant in the multiparty call room through the call sign transferring platform.

In an embodiment of the present disclosure, first, a multimedia data stream of each first call participant is sent to a call sign forwarding platform. And secondly, after receiving the multimedia data streams of the first call participants, the call forwarding platform sends the multimedia data streams of the first call participants to the application server.

Here, first, after receiving the multimedia data streams of the respective first call participants, the application server may mix the multimedia data streams of the respective first call participants through a media service unit in the application server to obtain a mixed stream of media data streams (i.e., target data). And then, after obtaining the media data stream after the mixed stream, the media data stream can be sent to a call sign transferring platform. And finally, the mixed media data stream can be sent to each first call participant in the multiparty call room through the call sign transferring platform.

In an embodiment of the present disclosure, the application server is a device disposed in an IMS network. Firstly, after each first call participant accesses the multiparty call room, the generated multimedia data stream is directly sent to the application server. Then, the multimedia data streams of the first call participants may be mixed by a media service unit in the application server, to obtain a mixed stream of media data streams (i.e., target data). The mixed media data stream may then be sent to a translation number platform. And finally, the mixed media data stream can be sent to each first call participant in the multiparty call room through the call sign transferring platform.

In the above embodiment, by configuring the application server outside the IMS network and describing the mixing process of the multimedia data streams of each first call participant, flexibility of deployment of the system and efficient management of multimedia data are demonstrated.

In an alternative embodiment, the method further comprises the steps of:

Firstly, after detecting that a multiparty call room is closed, determining a plurality of charging items of the multiparty call room;

And secondly, settling each charging item to obtain a settlement result of each calculation item.

In an embodiment of the present disclosure, a plurality of billing items for a multi-party call room is determined after a multi-party call room shutdown is detected. After detecting that each first call participant and each second call participant in the multiparty call room are on-hook or the call initiator manually closes the multiparty call room at the service operation management platform, the multiparty call room is automatically closed. At this time, the room number of the multiparty call room is controlled to be unbound with the corresponding call number, and the unbound call number and room number are recovered.

Here, a plurality of billing items of the multiparty call room are determined. The settlement of each calculation item can be obtained according to the communication time of each first participant and each second participant (namely, the time of joining in the multiparty communication room) according to the charging items.

Wherein the charging item is a value added service (i.e., service configuration) selected by the call initiator.

In the above embodiment, after the multiparty call room is closed, the charging items can be determined and settled, so that the multiparty call service can perform accurate charge calculation and support the charging management system of the service provider.

Referring to fig. 2, a flowchart of a multiparty call processing method according to an embodiment of the present disclosure is shown, where the method includes steps S301 to S303, applied to an edge node, where:

S301, responding to a call access operation of a first call participant, and sending a call access request of the first call participant to an application server; and the call request is carried by the call access request and comprises a call forwarding number of the multiparty call room.

In the embodiment of the present application, the call sign platform in the edge node may detect a call access operation of the first call participant, where a method for detecting the call access operation will be described in the following embodiments. After detecting the call access operation, a call access request of the first call participant may be sent to the application server.
