and synthesizing voice service data of at least two terminals in other communication terminals except the first communication opposite terminal, and sending the synthesized voice service data to the first communication opposite terminal through the voice service path, wherein the first communication opposite terminal is an opposite terminal corresponding to the second user identification card.
Optionally, the establishing a plurality of voice service paths with a plurality of opposite terminals based on each subscriber identity card includes:
establishing a data service path based on the first subscriber identity module card;
establishing a voice special bearer corresponding to each user identification card based on the data service path;
and establishing voice service paths between the opposite call terminals corresponding to the user identification cards on the basis of the voice special bearer.
Further, the method may further include:
establishing a video service path between each user identification card and an opposite terminal for carrying out video call;
receiving video service data of the video service channel;
and sending the video service data of the opposite end corresponding to the first user identification card to the opposite end corresponding to the second user identification card.
The multi-channel service data stream can exist simultaneously, the service data comprises voice service data, video service data and the like, and each card of the multi-card terminal can also support the multi-channel function.
Optionally, the Data service path is used for service Data transmission, and may be a path used for Data transmission under various service types, for example, in VoLTE and VoWiFi services, the Data service path may be a path corresponding to an IP Multimedia Subsystem Packet Data Network (IMS PDN for short) in an IP-based Multimedia Network.
Specifically, when a video service path is established with an opposite terminal performing a video call, first, a video-specific bearer corresponding to each subscriber identity card is established based on the data service path; and then establishing a video service path between opposite ends for carrying out video call corresponding to each user identification card based on the video special bearer.
Specifically, the sending the video service data of the terminal itself and at least two terminals in other call opposite terminals except the second call opposite terminal to the second call opposite terminal through the video service path includes:
mixing the video service data of the terminal and at least two terminals of other call opposite terminals except the second call opposite terminal, and sending the video service data to the second call opposite terminal through the video service path; or,
and directly sending the video service data of the terminal and at least two terminals of other call opposite ends except the second call opposite end to the second call opposite end through the video service path.
The method for implementing the conference call function provided by the embodiment of the invention is described in detail below with reference to specific examples.
In this embodiment, the home terminal as the conference host is a multi-card multi-channel terminal supporting VoLTE, and realizes the function of the conference server. The opposite call end of the conference participant can be a multi-pass terminal supporting VoLTE, or a terminal supporting call through a 2G/3G Circuit Switch (CS).
The mode that the host initiates the conference through the multi-communication terminal can be that a plurality of numbers are dialed out by one key, or the numbers are respectively dialed and then sequentially added into the conference.
As shown in fig. 2, the following description will take the example of a host's multi-card multi-pass terminal dialing out two users, namely, callNo1 and callNo2, to perform a video conference call. The specific implementation process is as follows:
step 1, the host multi-channel terminal dials the video call of callNo1 based on the card 1, and dials the video call of callNo2 based on the card 2.
The two paths of calls called out by the host multi-card multi-channel terminal can be simultaneously voice, video, one voice and one video. In this embodiment, both callNo1 and callNo2 that the moderator multi-way terminal calls are videos.
The contact header field of the conference call request INVITE message sent by the host multi-card multi-pass terminal contains the isfocus header field value, and indicates that the host initiates a conference call. If the participant is also a VoLTE terminal, it may be shown to the user that a conference call invitation is received. If not a VoLTE terminal, e.g. a 2G/3G terminal, the participants are not able to display conference call information. Wherein, the contact header field contains video, which indicates that the terminal supports video capability.
Step 2, establishing an IMS PDN 1 based on the card 1, establishing a voice special bearer debar 1 based on the IMS PDN 1, establishing a video special bearer debar 2 based on the IMS PDN 1, establishing a voice service path connect 1 corresponding to the callNo1 based on the voice special bearer debar 1, establishing a voice service path connect 2 corresponding to the callNo2 based on the voice special bearer debar 1, establishing a video service path connect 3 corresponding to the callNo1 based on the video special bearer debar 2, and establishing a video service path connect 4 corresponding to the callNo2 based on the video special bearer debar 2.
The negotiation process between the host multi-pass terminal and the opposite call terminal may be completed before the 200OK message corresponding to the INVITE, for example, through messages such as 183(Session Progress), UPDATE, and the like, or may be completed in the 200OK message corresponding to the INVITE, and the Session negotiation is 183 as an example in this embodiment.
If the first session negotiation between the multi-channel terminal of the host and the opposite communication terminal is carried out, the coding modes of the audio (audio) are different. In order to facilitate the processing of the multi-channel terminal of the host, the multi-channel terminal of the host can reinitiate the INVITE request and renegotiate with the opposite call terminal. After renegotiation, the encoding modes of the multi-pass terminal of the host and each conversation terminal are consistent as much as possible, so that the terminal sound mixing processing process can be simplified.
And 3, the host multi-channel terminal receives the voice from the callNo1 through the voice service path connect 1, receives the voice from the callNo2 through the voice service path connect 2, receives the video from the callNo1 through the video service path connect 3 and receives the video from the callNo2 through the video service path connect 4.
Step 4, the host multi-way terminal performs sound mixing on the voice from the callNo1 and the voice from the callNo2, performs sound mixing on the voice per se and the voice from the callNo1 and sends the voice to the callNo2, and performs sound mixing on the voice per se and the voice from the callNo2 and sends the voice to the callNo 1; the host multi-channel terminal sends the video of the host and the video from the callNo1 to the callNo2, and sends the video of the host and the video from the callNo2 to the callNo 1.
Thus, the host can hear a mix of callNo1 and callNo2, callNo1 can hear a mix of the host and callNo2, and callNo2 can hear a mix of the host and callNo 1; the moderator multi-way terminal can display the video of callNo1 and callNo 2; callNo1 can display video of the presenter and callNo 2; callNo2 can display video of the presenter and callNo 1.
Specifically, the video processing module in the host multi-channel terminal may perform mixing processing on the received multiple channels of video, for example, for a picture displayed by the host multi-channel terminal, images of callNo1 and callNo2 are simultaneously displayed in each picture of the video, and images of callNo1 and callNo2 may also be displayed respectively, that is, directly displayed without performing mixing processing.
If the video processing module performs mixing processing, the video processing module mixes the image of the host and the callNo2 and sends the mixed image to the callNo1, and the video processing module mixes the image of the host and the callNo1 and sends the mixed image to the callNo 2.
If the video processing module does not perform the blending process, the video processing module directly forwards the image of callNo1 to callNo2, and directly forwards the image of callNo2 to callNo 1.
Thus, the presenter multi-card multi-pass terminal can display images of callNo1 and callNo2, callNo1 can display video of the presenter and callNo2, and callNo2 can display video of the presenter and callNo 1.
The method for realizing the conference call provided by the embodiment of the invention establishes a plurality of voice service paths based on each user identification card and a plurality of opposite terminals, receives the voice service data of the voice service paths, and sends the voice service data of the opposite terminal corresponding to the first user identification card to the opposite terminal corresponding to the second user identification card. Compared with the prior art, the method and the system for establishing the conference call at the multi-card and multi-channel terminal can simplify the establishment process of the conference call, reduce the redundancy of video combination and ensure the success rate of establishing the conference call.
