[0017] Embodiments of the present invention will be described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0018] The control scheme of the NFC chip provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0019] Figure 1 A flowchart of a method for controlling multiple audio channels in an embodiment of the present application is shown. The method 100 can be executed by a first electronic device, wherein the first electronic device can be a server, for example, the first electronic device can be a multipoint control unit (MCU) of a video conferencing system, which is not limited in the embodiment of the present application. In other words, the method can be executed by software or hardware installed on the first electronic device. Figure 1 As shown, the method may include the following steps.

[0020] S110: Receive a first control instruction sent by a first terminal.

[0021] The first terminal is at least one terminal that has joined the main audio channel.

[0022] It can be understood that in a conference room, each user has a terminal and an electronic device corresponding to the terminal. The electronic device can be a first electronic device (i.e., a multipoint control unit (MCU)). The multipoint control unit has the ability to collect and play audio and the ability to communicate with the terminal. The communication capability can include the transmission of audio data, control instructions, etc.; each terminal also has the ability to collect and play audio and the ability to communicate with the multipoint control unit. The communication capability can include the transmission of audio data, control instructions, etc. Among them, when the multipoint conference unit holds a conference that supports multiple audio channels, it will first select one of the audio channels as the main audio channel to transmit audio that all users can listen to to ensure the normal progress of the conference. Therefore, the terminal corresponding to each user has been added to the main audio channel. When the first terminal has a need for group discussion, a first control instruction can be sent to the multipoint control unit. The first control instruction can be used to instruct the multipoint control unit to allocate an audio sub-channel to the first terminal. The multipoint control unit will perform corresponding operations according to the first control instruction, wherein the first terminal includes at least one terminal.

[0023] S120: Select a first audio sub-channel for the first terminal, and send information of the first audio sub-channel to the first terminal, where the first audio sub-channel is an audio channel other than the main audio channel.

[0024] It can be understood that the multipoint control unit can select the first audio subchannel for the first terminal according to the first control instruction, wherein the first audio subchannel can be an idle audio subchannel or created by the multipoint control unit based on the first control instruction. After the multipoint control unit selects the first audio subchannel for the first terminal, the information of the first audio subchannel is sent to the first terminal, and the first terminal can join the first audio subchannel according to the information of the first audio subchannel.

[0025] S130: Send activation information of the first audio sub-channel to the second terminal that has joined the audio main channel.

[0026] The activation information includes a first channel identifier of the first audio sub-channel, and the second terminal is a terminal other than the first terminal among at least one terminal that has joined the main audio channel.

[0027] It can be understood that, when the first audio sub-channel is selected according to the first control instruction, in addition to sending information of the first audio sub-channel to the first terminal, activation information of the first audio sub-channel can also be sent to other terminals other than the first terminal that have joined the audio main channel, that is, the second terminal, wherein the activation information includes the first channel identifier of the first audio sub-channel.

[0028] S140: Receive a request for joining the first audio sub-channel sent by at least one of the second terminals.

[0029] That is, after receiving the activation information of the first audio sub-channel sent by the multipoint control unit, the second terminal can choose whether to join the first audio sub-channel according to the first channel identifier in the activation information. After at least one second terminal chooses to join the first audio sub-channel, the multipoint control unit will receive requests sent by these terminals to join the first audio sub-channel.

[0030] S150: Add the at least one second terminal to the first audio sub-channel.

[0031] It can be understood that after receiving a request to join the first audio sub-channel sent by at least one second terminal, the multipoint control unit will add these terminals to the first audio sub-channel.

[0032] In an embodiment of the present application, in a multipoint conference with a main audio channel, a first control instruction sent by a first terminal is received to select a first audio sub-channel for the first terminal, and the activation information of the first audio sub-channel is sent to other terminals other than the first terminal, namely the second terminal, so that the second terminal can also choose whether to join the first audio sub-channel, and can allocate audio sub-channels to users who have group discussion or free discussion needs, thereby realizing free discussion between users without affecting the convening of the main meeting, making multipoint conferences more flexible, and being able to attract more users to participate, thereby effectively improving the efficiency of the meeting.

[0033] Figure 2 Another flow chart of the method for controlling multiple audio channels in the embodiment of the present application is shown. The method 200 can be executed by a first electronic device, which can be an MCU. In other words, the method can be executed by software or hardware installed on the first electronic device. Figure 2 As shown, the method may include the following steps.

[0034] S210: Receive a first control instruction sent by a first terminal.

[0035] The first terminal is at least one terminal that has joined the main audio channel.

[0036] S220: Select a first audio sub-channel for the first terminal, and send information of the first audio sub-channel to the first terminal, where the first audio sub-channel is an audio channel other than the main audio channel.

[0037] S230: Send activation information of the first audio sub-channel to a second terminal that has joined the audio main channel, wherein the activation information includes a first channel identifier of the first audio sub-channel, and the second terminal is a terminal other than the first terminal among at least one terminal that has joined the audio main channel.

[0038] S240: Receive a request for joining the first audio sub-channel sent by at least one of the second terminals.

[0039] S250: Add the at least one second terminal to the first audio sub-channel.

[0040] It should be noted that S210 to S250 can refer to Figure 1 The description of S110 to S150 in the embodiment will not be repeated here.

[0041] S260: Receive a request for exiting the first audio sub-channel sent by a target terminal that has joined the first audio sub-channel.

[0042] The request carries the identifier of the first audio sub-channel.

[0043] That is, when the target terminal joining the first audio subchannel chooses to exit the first audio subchannel, the multipoint control unit receives a request to exit the first audio subchannel sent by the target terminal, and the request to exit the target audio channel includes the identifier of the first audio subchannel.

[0044] S270: Delete the target terminal from the call members of the first audio sub-channel.

[0045] It is understandable that the multipoint control unit will, according to the request in S260 and based on the identifier of the first audio subchannel carried in the request, close the user of the target terminal's use of the first audio subchannel, i.e., delete the target terminal from the call members of the first audio subchannel.

[0046] Optionally, after deleting the target terminal from the call members of the first audio sub-channel, the multipoint control unit sends a confirmation message to the target terminal, and the confirmation message can be used to notify the user of the target terminal that the user has successfully exited the first audio sub-channel.

[0047] In an embodiment of the present application, a first audio sub-channel is selected for the first terminal by receiving a first control instruction sent by the first terminal, and the activation information of the first audio sub-channel is sent to other terminals other than the first terminal, namely the second terminal, so that the second terminal can also choose whether to join the first audio sub-channel. When the target terminal that has joined the first audio sub-channel needs to exit the first audio sub-channel, the multi-point control unit will agree to the target terminal to exit the first audio sub-channel according to the request sent by the target terminal. The creation of an open sub-conference in a multi-point conference with a main audio channel and at least one audio sub-channel is realized, that is, the user can freely join or exit the sub-conference corresponding to at least one audio sub-channel, making the multi-point conference more flexible, not only can it attract more participants to participate, but also when the audio sub-channel is not needed for discussion, choosing to exit can also avoid occupying the audio sub-channel and wasting network resources.

[0048] In one implementation, after deleting the target terminal from the call members of the first audio sub-channel, the method further includes: querying the number of call members of the first audio sub-channel; when the number of call members of the first audio sub-channel is 0, closing the first audio sub-channel and releasing the occupied resources of the first audio sub-channel. It is understandable that after deleting the target terminal from the call members of the first audio sub-channel, it is necessary to query the current usage information of the first audio sub-channel; when the number of call members is 0, it is possible to choose to close the first audio sub-channel and release the occupied resources of the first audio sub-channel, so as to avoid wasting conference resources and network resources.

[0049] In one implementation, the method further includes: if it is determined that there is no audio data transmission in the first audio subchannel within a predetermined time period, closing the first audio subchannel. In this implementation, the absence of audio data transmission in the first audio subchannel indicates that the number of call members in the first audio subchannel is 0 or the number of call members in the first audio subchannel is 0 but no one is discussing within the predetermined time period, and the first audio subchannel can be closed to avoid occupying system resources, so that the system resources corresponding to the first audio subchannel can be released, thereby ensuring efficient use of system resources.

[0050] In one implementation, before receiving the first control instruction sent by the first terminal, it also includes: establishing at least one sub-audio channel with each terminal that has joined the main audio channel. Among them, in one implementation, selecting the first audio sub-channel for the first terminal includes: selecting an idle audio sub-channel from the at least one sub-audio channel as the first audio sub-channel. It can be understood that before receiving the first control instruction sent by the first terminal, at least one sub-audio channel has been established in the multipoint conference. When the first terminal needs an audio sub-channel, the multipoint control unit can quickly select an idle audio sub-channel for the first terminal as the first audio sub-channel, which can avoid the problem of the first terminal waiting too long due to the need to establish an audio sub-channel. In this implementation, at least one sub-audio channel is established in advance, and sub-audio channels can be allocated in time for users in need, thereby effectively improving the efficiency of the meeting.

[0051] Figure 3 A flowchart of a method for adding an audio channel in an embodiment of the present application is shown. The method 300 can be executed by a second electronic device, wherein the first electronic device can be a terminal device, for example, a video conferencing terminal in a video conferencing system. The specific embodiments of the present application are not limited. In other words, the method can be executed by software or hardware installed on the second electronic device. The following takes the second electronic device as the first terminal as an example to illustrate the technical solution provided in the embodiment of the present application. Figure 3 As shown, the method may include the following steps.

[0052] S310: The first terminal sends a first control instruction to the multipoint control unit.

[0053] The first control instruction is used to apply for opening a first audio sub-channel for a user of the first terminal, and the first terminal is at least one terminal that has joined the audio main channel.

[0054] It is understandable that when the user of the first terminal needs a sub-conference for discussion, a first control instruction can be sent to the multipoint control unit to enable the multipoint control unit to open a first audio sub-channel for the user of the first terminal. Figure 1 The description of the main audio channel in the embodiment will not be repeated here.

[0055] S320: Receive information about the first audio sub-channel sent by the multipoint control unit.

[0056] The information includes a first channel identifier of the first audio subchannel.

[0057] It is understandable that after the multipoint control unit allocates the first audio sub-channel to the first terminal, the identifier of the first audio sub-channel may be sent to the first terminal so that the first terminal can join the first audio sub-channel through the identifier of the first audio sub-channel.

[0058] S330: Add the audio data of the first terminal to the first audio sub-channel.

[0059] That is to say, after receiving the identifier of the first audio sub-channel sent by the multi-point control unit, the first terminal can join the first audio sub-channel according to the identifier, that is, add the audio data of the first terminal to the first audio sub-channel, which allows the user of the first terminal to have a free discussion in the first audio sub-channel.

[0060] In an embodiment of the present application, the user of the first terminal applies to open a first audio sub-channel by sending a first control instruction to the multi-point control unit. After receiving the information of the first audio sub-channel sent by the multi-point control unit after opening the first audio sub-channel, the audio data of the first terminal is added to the first audio sub-channel. The user of the first terminal realizes free discussion without affecting the convening of the main meeting, thereby effectively improving the meeting efficiency.

[0061] Furthermore, in one implementation, the method further includes: sending a request to exit the first audio sub-channel to the multipoint control unit. Wherein, in one implementation, the method further includes: in response to the received operation instruction, switching the audio data of the first terminal to the audio main channel. It can be understood that in the present application, the first audio sub-channel created by the multipoint control unit is open, that is, an open sub-conference, and each user in the sub-conference corresponding to the first audio sub-channel can freely choose to join or exit. When the first terminal chooses to exit the first audio sub-channel, it can send a request to exit the first audio sub-channel to the multipoint control unit, and the multipoint control unit will respond to the request and perform the corresponding operation. After the multipoint control unit completes the operation, it will send an operation instruction to the first terminal so that the first terminal switches the audio data of the corresponding user to the audio main channel. In this implementation, the user can freely join or exit the sub-conference corresponding to at least one audio sub-channel. When the user joins only one audio sub-channel, when exiting, the user can choose to switch the audio data of the corresponding user to the audio main channel. Optionally, the user can also choose to join other audio sub-channels after exiting the first audio sub-channel.

[0062] In one implementation, the method further includes: receiving usage information of each audio subchannel sent by the multipoint control unit, wherein the usage information includes usage status and number of users. It is understandable that the multipoint control unit can send usage information of each audio subchannel to each terminal regularly or irregularly, so that each terminal can timely understand the usage information of each audio subchannel, thereby attracting more users to participate in the free discussion.

[0063] Below through Figure 4 A specific embodiment of the present application is described as follows. Figure 4 As shown, the embodiment may include the following steps.

[0064] S405: Convene a multi-point conference with multiple audio channels.

[0065] When holding a multi-point conference with multiple audio channels, in addition to creating H245 standard audio channels, you can also create multiple free discussion 1 audio channels, such as audio channel M and audio channel N, through H245 non-standard signaling.

[0066] S410: Sending a control instruction for free discussion.

[0067] A user corresponding to the first terminal creates a control instruction for free discussion through an access device and sends the instruction to the first terminal. After receiving the instruction, the first terminal forwards the instruction to the multipoint control unit MCU.

[0068] S415: Open the audio channel M.

[0069] After receiving the control instruction, the MCU selects an idle audio channel M.

[0070] S420: Send the information of the audio channel M.

[0071] The MCU returns the channel information to the first terminal.

[0072] S425: Broadcast the information of audio channel M.

[0073] The MCU broadcasts the channel information to each venue terminal: "Audio channel M is in use, and users can join the discussion." Optionally, the MCU can also push the usage status of each audio channel to each venue terminal (idle, usage status, such as venue user information).

[0074] S430: The first terminal joins the audio channel M.

[0075] After receiving the MCU response, the first terminal puts the audio of the user corresponding to the first terminal into the audio channel M and transmits it to the MCU, and sends the audio information from the MCU on the channel to the user corresponding to the first terminal; the user corresponding to the first terminal completes joining the audio channel M and participates in the discussion.

[0076] S435: The second terminal applies to join the audio channel M.

[0077] After receiving the push from the MCU, a user corresponding to the second terminal sends a control instruction to join the audio channel M to the second terminal through the access device.

[0078] S440: The second terminal joins the audio channel M.

[0079] After receiving the control signaling sent by the corresponding user, the second terminal puts the audio information of the corresponding user into the audio channel M for transmission, and sends the audio data obtained from the audio channel M to the user corresponding to the second terminal; the user corresponding to the second terminal completes joining the audio channel M and participates in the discussion.

[0080] S445: Query the usage of each audio channel.

[0081] The terminal can query the MCU about the usage of each audio channel. The MCU also regularly pushes this information to the terminal;

[0082] S450: Pushing usage status of each audio channel to each terminal.

[0083] The MCU can periodically push the usage status of each audio channel to the terminal.

[0084] S455: Monitor each audio channel regularly.

[0085] The MCU can monitor the status of each audio channel at regular intervals and release unused channels.

[0086] S460: The first terminal can freely switch audio channels.

[0087] The user corresponding to the first terminal can freely switch among the used audio channels.

[0088] S465: The second terminal can freely switch audio channels.

[0089] The user corresponding to the second terminal can freely switch among the used audio channels.

[0090] It should be noted that, in this embodiment, only the first terminal and the second terminal are used as examples for description, and a multipoint conference may include multiple terminals, for example, Figure 5 shown.

[0091] In the above embodiment, the multipoint conference unit holds a conference that supports multiple audio channels, and selects one of them as the main audio channel to transmit audio that can be listened to by all venues, ensuring the normal progress of the meeting; when the speaker mentions a question and participants from different venues need to discuss it, they can send a control instruction to the terminal through the access device to let it select an idle audio channel to join, and send a banner subtitle to remind other venues that "this channel has been used by default"; after seeing this, other participants send instructions through their own access devices to join the discussion; at the same time, the multipoint control unit will also detect the audio status of the channel and decide whether to release it to ensure that the audio channel can be recycled. This enables users to switch freely between different audio channels and have free discussions without affecting the normal convening of meetings.
