Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a conference joining method, device, terminal equipment, cloud server and conference system of a conference system. Background Art

[0002] When multiple terminal devices that are close to each other in a closed place are making voice calls, if the audio playback module and audio collection module of each terminal device are turned on, howling is likely to occur. For example, in the same offline conference room, when a mobile phone and a large conference screen are connected to the same online conference, if the voice played on the large conference screen is collected by the mobile phone and retransmitted to the large conference screen, the large conference screen will amplify the voice and replay it, and this will be repeated, which is likely to generate large self-excited noise, thereby causing howling.

[0003] In the prior art, the server corresponding to the conference software can obtain the audio data collected by the terminal device during the conference, determine whether the terminal device is in a howling state by performing spectrum analysis on the audio data, and perform noise reduction processing on the audio data of the terminal device in the howling state, thereby eliminating the howling phenomenon. However, the server can only perform noise reduction processing after the howling occurs, which has a lag and affects the user experience. Summary of the invention

[0004] The present application provides a conference joining method, apparatus, terminal equipment, cloud server and conference system, which can effectively prevent the occurrence of howling in online conferences to a certain extent.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] In a first aspect, the present application provides a method for joining a meeting, which is applied to a first terminal device, and the method includes: in response to a joining operation on a first online meeting, determining whether a second terminal device located in a first area where the first terminal device is located has joined the first online meeting; if the second terminal device has joined the first online meeting, turning off the audio acquisition module and the audio playback module of the first terminal device, and joining the first online meeting.

[0007] Based on the joining method provided by the present application, after the first terminal device detects the user's joining operation on the first online conference, if it is determined that the second terminal device in the first area where the first terminal is located has joined the first online conference, then before the first terminal device joins the first online conference, the audio acquisition module and the audio playback module are turned off, so that the first terminal device neither collects nor plays audio data during the first online conference, thereby cutting off the audio loop that causes howling, and effectively preventing the howling phenomenon from occurring when multiple terminal devices that are close to each other in the same area join the same online conference.

[0008] In the embodiment of the present application, the first terminal device and the second terminal device can be portable electronic devices such as mobile phones, tablet computers, laptop computers, ultra-mobile personal computers, netbooks, personal digital assistants, desktop computers, etc. The second terminal device can also be a non-portable electronic device such as a large conference screen that can be fixed in an area.

[0009] Optionally, the audio collection module may be a microphone, and the audio playback module may be a speaker.

[0010] In a possible implementation of the first aspect, before determining whether a second terminal device located in a first area where a first terminal device is located has joined a first online meeting, the method further includes: sending first wireless fidelity (WiFi) information to which the first terminal device is connected to a cloud server, the first WiFi information being used to indicate the first area; the cloud server pre-stores a mapping relationship of at least one WiFi information, an area identifier, and device information, the device information being used to indicate a device status of a terminal device located in an area identified by a corresponding area identifier, and a conference identifier (identity document, ID) of an online conference to which the terminal device has joined when the device status is a joining state.

[0011] The cloud server is a conference management server corresponding to the conference software installed on the first terminal device. The first terminal device can obtain the device information of the second terminal device located in the first area from the cloud server when accessing the WiFi network provided by the wireless access device in the first area, and determine whether the second terminal device has joined the first online meeting.

[0012] Optionally, the WiFi information of the WiFi network may include the BSSID (basic service set identifier) ​​of the WiFi network in the corresponding area. In addition, it may also include the name service set identifier (SSID) of the WiFi network in the corresponding area. Among them, the SSID is used to indicate the network name of the WiFi network in the corresponding area, and the BSSID of the WiFi network is used to indicate the MAC address of the network site in the corresponding area. The BSSIDs of different WiFi networks are different, but multiple WiFi networks can have the same SSID.

[0014] In a possible implementation of the first aspect, determining whether a second terminal device located in a first area where a first terminal device is located has joined a first online meeting includes: receiving first device information corresponding to first WiFi information sent by a cloud server; if the first device information indicates that the second terminal device is in a meeting joining state, and the meeting ID of the online meeting that the second terminal device has joined is the same as the meeting ID of the first online meeting, then determining that the second terminal device has joined the first online meeting.

If the first terminal device is connected to a WiFi network, the first terminal device can send the first WiFi information corresponding to the connected WiFi network to the corresponding cloud server before joining the first online meeting in the conference software, so as to obtain the first device information of the second terminal device in the first area indicated by the first WiFi information from the cloud server, and then determine whether the second terminal device located in the first area is in a meeting state and whether it has joined the first online meeting based on the first device information.

[0016] In a possible implementation of the first aspect, Bluetooth broadcast information sent by the second terminal device is obtained; if the Bluetooth broadcast information indicates that the second terminal device is in a meeting state, and the conference ID of the online conference that the second terminal device has joined is the same as the conference ID of the first online conference, it is determined that the second terminal device has joined the first online conference.

[0017] Based on this possible implementation, if the first terminal device obtains the Bluetooth broadcast information sent by the second terminal device through the low-power Bluetooth scanning function, it means that the first terminal device and the second terminal device are close to each other and are both in the first area. The first terminal device can determine the device status of the second terminal device based on the obtained Bluetooth broadcast information, and when the device status is in the joining state, determine whether the second terminal device has joined the first online meeting through the conference ID of the conference that the second terminal device has joined, and then after determining that the second terminal device has joined the first online meeting, turn off the audio acquisition module and audio playback module of the first terminal device to avoid howling.

[0040] The technical solutions in the embodiments of the present application are described below in conjunction with the drawings and related embodiments in the embodiments of the present application. Among them, in the description of the embodiments of the present application, the terms used in the following embodiments are only for the purpose of describing specific embodiments, and are not intended to be used as limitations on the present application. As used in the specification and the appended claims of the present application, the singular expressions "a", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear indication to the contrary in the context. It should also be understood that in the following embodiments of the present application, "at least one", "one or more" refer to one or more (including two). The term "and / or" is used to describe the association relationship of associated objects, indicating that three relationships can exist; for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in a "or" relationship.

[0041] References to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Thus, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways. The term "connection" includes direct connection and indirect connection, unless otherwise specified.

[0042] In the embodiments of the present application, the words "exemplarily" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.

[0043] The steps involved in the membership method provided in the embodiments of the present application are only examples. Not all steps are mandatory, or not all information or messages are mandatory. They can be increased or decreased as needed during use. In the embodiments of the present application, the same step or steps or messages with the same function can be referenced and learned from each other in different embodiments.

[0044] In a closed venue such as a conference room, if multiple terminal devices that are close to each other join the same online meeting, and the audio playback module (for example, speaker) and audio acquisition module (for example, microphone) of each terminal device are in the turned-on state, the audio signal received by the audio acquisition module may be amplified and reproduced by the audio playback module. The audio acquisition module will receive the audio signal reproduced by the audio playback module again, which will then be further amplified by the audio playback module and reproduced at a higher amplitude or volume level. This process will be repeated, thereby causing howling.

[0045] In the prior art, the user can connect the terminal device to the headset of the peripheral device after howling occurs, so that the audio played by the terminal device is transferred from the speaker to the headset, avoiding the occurrence of echo and howling. In addition, some conference software is equipped with a noise reduction function. The conference management server corresponding to the conference software installed on the terminal device can obtain the audio data of the terminal device during the meeting, determine whether the terminal device is in a howling state by performing spectrum analysis on the audio data, and perform noise reduction processing on the audio data of the terminal device in the howling state, thereby eliminating the howling phenomenon. However, whether it is the howling elimination method in which the user actively intervenes using the headset, or the method in which the conference software automatically eliminates the howling, noise reduction processing can only be performed after the howling occurs, and there is a lag, which affects the user experience.

[0046] In order to solve the above problems, the embodiments of the present application provide a method, apparatus, terminal device, cloud server and conference system for joining a meeting. After the first terminal device detects the user's operation of joining a first online meeting, if it is determined that the second terminal device located in the first area where the first terminal device is located is in a meeting state and has joined the first online meeting, then before the first terminal device joins the first online meeting, the audio acquisition module and the audio playback module of the first terminal device are turned off, thereby cutting off the audio loop that may form a howling phenomenon in the same area, and effectively preventing the occurrence of the howling phenomenon.

[0047] Next, the conference system involved in the conference joining method provided in the embodiment of the present application is first introduced.

[0048] Figure 1 This is a schematic diagram of the structure of a conference system provided in an embodiment of the present application, see Figure 1 The conference system provided in the embodiment of the present application includes a first terminal device 110 and a second terminal device 120. In the conference system, the first terminal device 110 and the second terminal device 120 can communicate with each other through Bluetooth low energy (BLE) technology.

[0049] Specifically, the second terminal device 120 can start the low-power Bluetooth broadcast function to publish Bluetooth broadcast information in real time within the preset area through the low-power Bluetooth protocol broadcast channel. The first terminal device 110 can start the low-power Bluetooth scanning function to receive the Bluetooth broadcast information sent by the second terminal device 120 within the preset area. The first terminal device 110 can be used to detect that the user triggers the joining operation of the first online conference in the conference software on the first terminal device 110, and determine whether the second terminal device 120 has joined the first online conference according to the device state of the second terminal device 120 indicated by the Bluetooth broadcast information sent by the second terminal device 120, and the conference identity (identity, ID) of the online conference that the second terminal device 120 has joined when the device state is the joining state, and after determining that the second terminal device 120 has joined the first online conference, turn off the audio acquisition module and audio playback module of the first terminal device 110 and join the first online conference to prevent the phenomenon of howling when multiple terminal devices in the same area join the same line.

[0050] Optionally, the conference system provided in the embodiment of the present application further includes a cloud server 130 and a wireless access device 140. The cloud server 130 is an online conference management server corresponding to the conference software installed on the first terminal device 110 and the second terminal device 120, and the wireless access device 140 is used to provide a WiFi network signal for the terminal device. In the conference system, the first terminal device 110 can access the wireless fidelity (WiFi) network provided by the wireless access device 140, and communicate with the cloud server 130 through the conference software installed on the first terminal device 110. The second terminal device 120 can access the WiFi network provided by the wireless access device 140, or can be connected to the local area network based on a wired connection, and communicate with the cloud server 130 through the conference software installed on the second terminal device 120.

[0051] In the conference system, the second terminal device 120 is used to send device information to the cloud server 130 after joining an online conference or leaving an online conference. The device information can be used to indicate whether the second terminal device 120 is in a joining state and the conference ID of the online conference that has been joined when in the joining state. After the user triggers the joining operation of the first online conference in the conference software installed on the first terminal device 110, the first terminal device 110 can be used to obtain the first device information corresponding to the first WiFi information of the WiFi network to which the first terminal device 110 is connected through the cloud server 130. If it is determined according to the first device information that the second terminal device 120 located in the first area corresponding to the first WiFi information has joined the first online conference, the audio acquisition module and the audio playback module of the first terminal device 110 are turned off and join the first online conference, thereby preventing the phenomenon of howling when multiple terminal devices in the same area join the same line.

The memory may store instructions or data that the processor 210 has just used or cyclically used. If the processor 210 needs to use the instruction or data again, it may be directly called from the memory.

The demodulator is used to demodulate the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After the low-frequency baseband signal is processed by the baseband processor, it is passed to the application processor. The application processor outputs a sound signal through an audio device (not limited to a speaker 270A, a receiver 270B, etc.), or displays an image or video through a display screen 294.

[0139] The following is an exemplary description of the method for joining a meeting provided in the embodiment of the present application in combination with corresponding flow charts and specific application scenarios.

[0140] In one possible implementation, see Figure 5 A schematic diagram of a method of joining a membership Figure 1 The execution subject of the conference joining method is the first terminal device in the conference system. The method includes steps S510 to S520. Each step is described in detail below.

[0141] S510: In response to a joining operation on a first online conference, determining whether a second terminal device located in a first area where the first terminal device is located has joined the first online conference.

[0142] In one example, assuming that the first terminal device 110 is a mobile phone, see Figure 6 A schematic diagram of a display interface shown Figure 1 , the first terminal device 110 is installed with conference software. After the user logs in to the conference software, the display interface of the first terminal device 110 may display a join conference interface 610, which displays a conference ID edit bar 6101, a user name edit bar 6102, and a "join conference" button 6103. After the user enters the conference ID of the first online conference in the conference ID edit bar 6101 and the user name in the user name edit bar 6102, the user may click the "join conference" button 6103, thereby triggering the joining operation of the first online conference.

[0143] In another example, see Figure 7 A schematic diagram of a display interface shown Figure 2 , a drop-down combination button 61011, such as an inverted triangle button, may be set in the conference ID edit field 6101. After the user clicks the drop-down combination button 61011, a conference list 6104 may be displayed on the join conference interface 610. The conference list 6104 includes conference information of one or more online conferences to be joined by the user ( Figure 7 The conference list 6104 in the conference list only shows the conference information of three online conferences), and the conference information is not limited to the conference subject, conference time and conference ID of the online conference. The first terminal device 110 can display the corresponding conference ID of the first online conference in the conference ID editing field 6101 according to the user's click operation on the conference information of the first online conference in the conference list 6104, wherein the first online conference can be any one of the at least one online conference in the conference list, and after the user enters the user name in the user name editing field 6102, he can click the "join meeting" button 6103, thereby triggering the joining operation of the first online conference.

[0144] In the embodiment of the present application, the first area may be an offline conference room, and the first terminal device may be a portable electronic device that is movable and currently located in the first area. There may be one or more second terminal devices located in the first area where the first terminal device is located. Specifically, the second terminal device located in the first area may be a non-portable electronic device that is fixedly arranged in the first area, or may be a portable electronic device that is movable and currently located in the first area.

[0145] After the user triggers the joining operation of the first online conference on the first terminal device, the first terminal device can obtain the device information of the second terminal device located in the first area, and judge whether the second terminal device located in the current first area has joined the first online conference by the obtained device information of the second terminal device in the first area, and then determine whether it is necessary to cut off the audio loop that is prone to howling when the first terminal device joins the first online conference.

[0146] It should be noted that when there are multiple different second terminal devices in the first area, the first terminal device needs to obtain device information of each second terminal device located in the first area, and determine whether each second terminal device located in the first area has joined the first online meeting through the obtained device information.

[0147] S520: If the second terminal device has joined the first online conference, close the audio collection module and the audio playback module of the first terminal device, and join the first online conference.

[0148] Specifically, if the first terminal device determines that any one or more second terminal devices located in the first area have joined the first online meeting, in order to avoid the audio acquisition modules and audio playback modules of multiple terminal devices in the first area being in the turned-on state and causing howling when multiple terminal devices join the same online meeting, the first terminal device can turn off the audio acquisition module and audio playback module of the first terminal device before joining the first online meeting, so that the first terminal device neither outputs audio signals nor collects audio signals during the first online meeting, thereby cutting off the loop that may cause howling in the first area and preventing the occurrence of howling.

[0149] Among them, the audio acquisition module of the first terminal device is a microphone, and the audio playback module is a speaker.

[0150] See also Figure 8 A schematic diagram of a display interface shown Figure 3After the user triggers the joining operation of the first online conference, the first terminal device 110 can turn off the audio acquisition module and the audio playback module of the first terminal device 110 and join the first online conference after determining that the second terminal device in the first area has joined the first online conference. Correspondingly, the display interface of the first terminal device 110 can display the conference interface 620 of the first online conference, and the microphone logo 6201 and the speaker logo 6202 in the conference interface 620 are both displayed as closed.

[0151] In the above step S510, the first terminal device can obtain the device information of any second terminal device in the first area through different implementation methods, and determine whether the corresponding second terminal device has joined the first online meeting based on the device information. When the conference system does not include a cloud server and a wireless access device, the first terminal device can obtain the device information of the second terminal device located in the first area and determine whether the second terminal device has joined the first online meeting through the following method 1. When the conference system includes a cloud server and a wireless access device, the first terminal device can obtain the device information of the second terminal device located in the first area and determine whether the second terminal device has joined the first online meeting through the following method 2.

[0152] In conjunction with the corresponding flow chart, the process of the first terminal device determining whether the second terminal device located in the first area where the first terminal device is located has joined the first online conference through two different implementation methods is specifically described below.

[0153] Method 1

[0154] The first terminal device can directly obtain the corresponding device information from the second terminal device through the low-power Bluetooth scanning function, and determine whether the second terminal device has joined the first online meeting. Fig. 9 As shown in the schematic flow chart, the method includes steps S910 to S920. Each step is described in detail below.

[0155] S910, the first terminal device obtains the Bluetooth broadcast information sent by the second terminal device.

[0156] Specifically, the terminal devices located in each area can start the low-power Bluetooth broadcast function to publish Bluetooth broadcast information in real time in the corresponding area through the low-power Bluetooth protocol broadcast channel.

[0157] Taking the second terminal device located in the first area as an example, the content of the Bluetooth broadcast information is exemplarily described. Specifically, the Bluetooth broadcast information of the second terminal device may include the device information of the second terminal device, and the device information includes the device identification and device status of the second terminal device. Among them, the device status is used to indicate whether the second terminal device is in an online meeting, and the device status can be a joining status or a leaving status. In addition, when the device status of the second terminal device is a joining status, the device information of the second terminal device also includes the conference ID of the online meeting that the second terminal device has joined.

[0158] Exemplarily, the device identifier of the second terminal device may be a media access control (MAC) address, an international mobile equipment identity (IMEI), a unique device identifier (UDID), etc. of the second terminal device. The meeting information of the online meeting may include the meeting ID of the online meeting, and may also include a meeting password for the online meeting, etc.

[0159] Optionally, the Bluetooth broadcast information also includes an area identifier of the first area where the corresponding second terminal device is located. If the second terminal device is a non-portable electronic device fixedly set in the first area, the area identifier of the first area where the second terminal device is located can be pre-stored in the second terminal device so that the second terminal device can publish the Bluetooth broadcast information in real time in the first area, wherein the area identifier in the Bluetooth broadcast information can be used to indicate information such as the specific floor and room number of the first area where the second terminal device is located. If the second terminal device is a portable electronic device such as a mobile phone that can be moved to different areas (i.e., not fixed in the first area), the area identifier of the first area where the second terminal device is located can be the geographical location information of the first area where the second terminal device is located, obtained by the second terminal device through the global positioning system (GPS), the building positioning system (BPS) and / or the indoor positioning system (IPS), and the geographical location information includes but is not limited to information such as longitude, latitude, specific floor or room number; or when the second terminal device accesses a WiFi network in the first area, the area identifier of the first area where the second terminal device is located can be the WiFi information of the WiFi network in the first area to which the second terminal device is connected, and the WiFi information can include a basic service set identifier (BSSID) of the WiFi network, and in addition, can also include a service set identifier (SSID) of the WiFi network.

[0160] It should be noted that the length of data that can be transmitted in a Bluetooth broadcast is limited. In one embodiment, if the data length in the Bluetooth broadcast information is greater than the preset data length, the second terminal device can cyclically publish multiple different broadcast contents in a preset order, and each broadcast content can correspond to the device status of the second terminal device in the Bluetooth broadcast information, the conference information of the online conference that the second terminal device has joined when the conference status of the second terminal device is the joining status, the device identification of the second terminal device, and the area identification of the first area where the second terminal device is located.

[0161] As an example but not a limitation, if the conference status of the second terminal device located in the first area is the joining state, the second terminal device can cyclically publish four different broadcast contents in the order of "conference status, conference information of the online conference joined, device identification, and area identification of the area where it is located", wherein the first broadcast content can be "InMeeting: true", which is used to indicate that the conference status of the second terminal device is the joining state; the second broadcast content can be "MeetingId: 98123456", which is used to indicate that the conference ID of the online conference joined by the second terminal device is 98123456; the third broadcast content can be "Mac: ECD68A84CD41", which is used to indicate that the device identification (ie, MAC address) of the second terminal device is ECD68A84CD41; the fourth broadcast content can be "RoomName: H-F1-12A", which is used to indicate that the first area where the second terminal device is located is Room 12A, Building F1, Area H. The first terminal device can sequentially receive the four different broadcast contents published by the second terminal device through the low-power Bluetooth scanning function, thereby obtaining the Bluetooth broadcast information of the second terminal device.

[0162] In another embodiment, in order to shorten the time it takes for the first terminal device to receive Bluetooth broadcast information and increase the speed of joining a meeting, the second terminal device can reduce the conference status of the second terminal device, the conference information of the online conference that the second terminal device has joined when the conference status of the second terminal device is the joining status, the device identifier of the second terminal device, and the area identifier of the first area where the second terminal device is located into one broadcast content in a preset order for cyclic publication, so that the data length of the broadcast content is less than or equal to the preset data length.

[0163] Exemplarily, if the conference status of the second terminal device is the joining status, the second terminal device can edit the broadcast content to "true; 98123456; ECD68A84CD41; H-F1-12A" according to the editing order of the conference status of the second terminal device, the conference information of the online conference that the second terminal device has joined when the conference status of the second terminal device is the joining status, the device identification of the second terminal device, and the area identification of the first area where the second terminal device is located, and play the broadcast content in a loop through the low-power Bluetooth broadcast function. The first terminal device receives the broadcast content published by the second terminal device through the low-power Bluetooth scanning function, and can obtain the Bluetooth broadcast information of the second terminal device.

[0164] In one implementation, after the user starts the low-power Bluetooth scanning function of the first terminal device, the first terminal device can receive the Bluetooth broadcast information sent by the second terminal device currently located in the first area within the current first area. That is to say, if the first terminal device can obtain the Bluetooth broadcast information sent by the second terminal device, the first terminal device can determine that the distance between itself and the second terminal device is relatively close and that it is located in the first area where the second terminal device is located.

[0165] In another implementation, the second terminal device can publish Bluetooth broadcast information containing the area identifier of the area where it is located in real time within the area where it is located, so that the first terminal device can determine whether the first terminal device and the second terminal device are in the same area based on the first area where it is currently located and the area identifier in the received Bluetooth broadcast information.

[0166] Specifically, after the user starts the low-power Bluetooth scanning function of the first terminal device, if the Bluetooth broadcast information sent by the second terminal device is received, and the Bluetooth broadcast information includes the area identifier of the area where the second terminal device is located, the first terminal device can first determine the area identifier of the first area where it is located, and then compare the area identifier of the first area where it is located with the area identifier sent by the second terminal device. If the two are the same, it can be determined that the second terminal device is a terminal device located in the first area where the first terminal device is located. Based on this method, if the first terminal device receives Bluetooth broadcast information sent by multiple terminal devices, the first terminal device can determine the distance between each terminal device and accurately determine the second terminal device located in the first area from multiple terminal devices.

[0167] Among them, the first terminal device in the present application is a portable electronic device that can be moved. The first terminal device can determine the area identification of the first area where it is located in different ways, and compare the area identification of the first area with the area identification sent by other terminal devices. Exemplarily, the first terminal device can obtain the geographical location information of the first area where it is located through the global positioning system, the building positioning system and / or the indoor positioning system, and use the geographical location information as the area identification of the first area where the first terminal device is located. The first terminal device can compare the longitude, latitude, specific floor and / or room number and other information included in the geographical location information with the location information indicated by the area identification sent by a terminal device through Bluetooth broadcast, and determine whether the terminal device is a second terminal device located in the first area. Alternatively, if the first terminal device has accessed the WiFi network in the first area, the first terminal device can use the WiFi information of the connected WiFi network in the first area as the area identification of the first area where it is located, and compare the WiFi information of the connected WiFi network in the first area with the WiFi information indicated by the area identification sent by a terminal device through Bluetooth broadcast, and determine whether the terminal device is a second terminal device located in the first area.

[0168] It should be noted that in method one, there is no need to establish a Bluetooth connection between the first terminal device and the second terminal device. After the first terminal device turns on the low-power Bluetooth scanning function and the second terminal device turns on the low-power Bluetooth broadcast function, the first terminal device can automatically receive the Bluetooth broadcast information sent by the second terminal device located in the first area where the first terminal device is located.

[0169] S920: If the Bluetooth broadcast information indicates that the second terminal device is in a conference joining state, and the conference ID of the online conference that the second terminal device has joined is the same as the conference ID of the first online conference, it is determined that the second terminal device has joined the first online conference.

[0170] The distance between the first terminal device and the second terminal device located in the first area is relatively close. If the two terminal devices are in the same online meeting at the same time, and the audio acquisition modules and audio playback modules of the two terminal devices are both in the on state, an audio loop that is prone to cause howling will be formed. Therefore, after receiving the Bluetooth broadcast information sent by the second terminal device, the first terminal device can first determine whether the device status of the second terminal device located in the first area is in the meeting state according to the Bluetooth broadcast information. After the first terminal device determines that the second terminal device located in the first area is in the meeting state, it determines whether the online meeting that the second terminal device has joined is the first online meeting to be joined by the first terminal device through the conference ID of the first online meeting and the conference ID of the online meeting that the second terminal device has joined in the Bluetooth broadcast information. If the online meeting that the second terminal device has joined is the first online meeting, the first terminal device can turn off the audio acquisition module and the audio playback module and join the first online meeting to prevent the occurrence of howling.

[0171] Method 2

[0172] The first terminal device can obtain the device information of the second terminal device located in the first area from the cloud server, and determine whether the second terminal device has joined the first online meeting. Fig.10 As shown in the schematic flow chart, the method includes steps S1010 to S1040. Each step is described in detail below.

[0173] S1010, the first terminal device sends first WiFi information to which the first terminal device has been connected to a cloud server, where the first WiFi information is used to indicate a first area.

[0174] In the embodiment of the present application, the cloud server may pre-store a mapping relationship between the regional identifiers of one or more regions, the corresponding WiFi information, and the device information of the terminal devices in the region. Based on this, when the first terminal device accesses the WiFi network provided by the wireless access device in the first region, after the user triggers the joining operation of the first online conference on the first terminal device, the first terminal device may send a device information acquisition request to the cloud server, and the device information acquisition request includes the first WiFi information to which the first terminal device itself has been connected, so that the cloud server can obtain the device information of the second terminal device in the first region indicated by the first WiFi information from the pre-stored mapping relationship based on the first WiFi information.

[0175] The area identifier of each area pre-stored in the cloud server can be used to indicate information such as the floor and room number of the corresponding area. The device information of the terminal device in the area can include the device status and device identifier of the terminal device. The device status is used to indicate whether the corresponding terminal device is in an online meeting. Specifically, the device status can be a joining state or a leaving state. When the device status of the terminal device is a joining state, the device information of the terminal device pre-stored in the cloud server also includes the conference ID of the online conference that the terminal device has joined.

[0176] The WiFi information of the WiFi network in each area may include the BSSID of the WiFi network in the corresponding area, and in addition, may also include the SSID of the WiFi network in the corresponding area. The SSID is used to indicate the network name of the WiFi network in the corresponding area, and the BSSID of the WiFi network is used to indicate the MAC address of the network station in the corresponding area.

[0177] It should be noted that generally, after a terminal device starts a WiFi connection, it will preferentially connect to the WiFi network with the strongest signal, and the closer the distance between the terminal device and a certain area, the stronger the WiFi network signal covered in the area retrieved by the terminal device. Therefore, if the first terminal device is connected to the WiFi network in a certain area, it means that the first terminal device is located in the area. In addition, generally, multiple areas can correspond to the same SSID, but the BSSID of each area is different. Therefore, when the first terminal device moves in different areas, the SSID of the connected WiFi network may not change, but the BSSID of the connected WiFi network will switch to the BSSID of the WiFi network in the corresponding area as the first terminal device moves.

[0178] For example, there are two conference rooms on one floor, namely Conference Room 1 and Conference Room 2. The two conference rooms correspond to two different areas. The SSID of the WiFi network in Conference Room 1 and the SSID of the WiFi network in Conference Room 2 can both be "wlanaccess2.0", but the BSSID of the WiFi network in Conference Room 1 is "9c50ee748e71", and the BSSID of the WiFi network in Conference Room 2 is "9c50ee748e72". When the first terminal device moves on the floor, it can automatically connect to the WiFi network in Conference Room 1 or the WiFi network in Conference Room 2 according to the relative distance between the first terminal device and Conference Room 1 or Conference Room 2. If the WiFi network to which the first terminal device is connected is the WiFi network in Conference Room 1, it means that the first area where the first terminal device is located is Conference Room 1. After the user triggers the joining operation for the first online conference on the first terminal device, the first WiFi information sent by the first terminal device to the cloud server includes the BSSID "9c50ee748e71" of the WiFi network in Conference Room 1; if the WiFi network to which the first terminal device is connected is the WiFi network in Conference Room 2, it means that the first area where the first terminal device is located is Conference Room 2. After the user triggers the joining operation for the first online conference on the first terminal device, the first WiFi information sent by the first terminal device to the cloud server includes the BSSID "9c50ee748e72" of the WiFi network in Conference Room 2.

[0179] In an embodiment of the present application, based on different types of second terminal devices, the cloud server can obtain the mapping relationship between the area identifier of at least one area, the corresponding WiFi information, and the device information of the terminal device located in the area in different ways.

[0180] Specifically, in one possible scenario, the second terminal device is a non-portable electronic device fixedly set in the first area. In this case, the cloud server may pre-store the area identifiers of multiple areas, the WiFi information in each area, and the device identifiers of the terminal devices fixedly set in each area. The cloud server may receive device information sent by a terminal device fixedly set in at least one area, wherein the device information includes the device identifier of the corresponding terminal device, the device status of the terminal device, and the conference ID of the online conference that the terminal device has joined when the device status is in the joining state. After receiving the device information of the terminal device, if the device identifier sent by the terminal device exists among the multiple device identifiers pre-stored in the cloud server, the cloud server determines the mapping relationship between the device information of the fixed terminal device, the area identifier of the area where the fixed terminal device is located, and the WiFi information in the area, and stores the mapping relationship.

[0181] In another possible scenario, the second terminal device is a portable electronic device that is movable and currently located in the first area. In this case, the cloud server can receive the mapping relationship between the device information of the terminal device, the area identifier of the area where the terminal device is located, and the WiFi information in the area sent by the movable terminal device to the cloud server, and store the mapping relationship.

[0182] Specifically, after the movable terminal device moves to a certain area, it can connect to the WiFi network covered in the area and obtain the area where it is located through the global satellite positioning system or the connected WiFi network. After joining or leaving an online meeting, the movable terminal device can send its own device information, the WiFi information of the WiFi network it has connected to, and the area identifier of the area where it is located to the cloud server, wherein the device information may include the device identifier of the movable terminal device and the device status of the movable terminal device, the device status may be the joining status or the leaving status, the device information may also include the conference ID of the online conference that the terminal device has joined when the device status is the joining status, the WiFi information may be the BSSID of the WiFi network covered in the area where the movable terminal device itself is located, and the area identifier may be the floor and room number corresponding to the area where the movable terminal device itself is located.

[0183] Furthermore, the device information of the terminal devices in each area pre-stored in the cloud server can be updated according to the device information sent by the terminal devices to the cloud server when joining or leaving an online meeting.

[0184] Exemplarily, after joining online conference 1, terminal device 1 in area 1 may send the area identifier of area 1 where terminal device 1 is located and the device information of terminal device 1 to the cloud server, where the device information includes the device identifier of terminal device 1, the device status of terminal device 1 being in the joining state, and the conference ID of the online conference that terminal device 1 has joined, wherein the device identifier of terminal device 1 may be the MAC address of terminal device 1, and the area identifier of area 1 may be the offline conference room number. Furthermore, after the user triggers the operation of leaving online conference 1 on terminal device 1, terminal device 1 may send the corresponding device information to the cloud server again, where the device information includes the device identifier indicating terminal device 1 and the device status of terminal device 1 being in the leaving state.

[0185] S1020, the cloud server determines the pre-stored first device information corresponding to the first WiFi information, the first device information is used to indicate the device status of the second terminal device in the first area indicated by the first WiFi information, and the conference ID of the online conference that the second terminal device has joined when the device status is the joining status.

[0186] Specifically, the first WiFi information may be the BSSID of the WiFi covered within the first area where the first terminal device is located. After receiving the first WiFi information sent by the first terminal device, the cloud server may determine the first device information of the second terminal device located within the first area indicated by the first WiFi information based on a mapping relationship between at least one pre-stored WiFi information, area identifier, and device information.

[0187] S1030, the cloud server sends the first device information to the first terminal device.

[0188] Optionally, the cloud server may also send the area identifier of the first area where the second terminal device is located to the first terminal device.

[0189] It should be noted that there may be one or more second terminal devices in the first area. When there are multiple second terminal devices in the first area, the cloud server can determine multiple different first device information corresponding to multiple different second terminal devices based on the first WiFi information, and send all the multiple first device information to the first terminal device.

[0190] S1040: After the first terminal device determines, based on the first device information, that the second terminal device has joined the first online conference, the first terminal device turns off the audio acquisition module and the audio playback module of the first terminal device, and joins the first online conference.

[0191] After the first terminal device receives the first device information of one or more second terminal devices, for the first device information of any second terminal device, if it is determined that the device status of the second terminal device in the first device information is a joining status, and the conference ID of the online conference that the second terminal device has joined in the first device information is the same as the conference ID of the first online conference that the first terminal device is to join, then it can be determined that the second terminal device has joined the first online conference.

[0192] The distance between the first terminal device and the second terminal device located in the first area is relatively close. If multiple terminal devices are in the same online meeting at the same time, and the audio acquisition modules and audio playback modules of the multiple terminal devices are all in the turned-on state, an audio loop that is prone to cause howling will be formed. Therefore, after the first terminal device determines that the second terminal device in the first area has joined the first online meeting, the first terminal device can turn off the audio acquisition module and the audio playback module of the first terminal device before joining the first online meeting, thereby cutting off the audio loop that generates howling and preventing the occurrence of howling.

[0197] Optionally, the communication unit 1120 is used to send first wireless fidelity WiFi information to which the first terminal device has been connected to the cloud server before the processing unit 1110 determines whether the second terminal device located in the first area where the first terminal device is located has joined the first online meeting, and the first WiFi information is used to indicate the first area; wherein the cloud server pre-stores at least one mapping relationship between WiFi information, area identifier and device information, and the device information is used to indicate the device status of the terminal device located in the area identified by the corresponding area identifier, and the conference identifier ID of the online conference that the terminal device has joined when the device status is the joining status.

[0198] Optionally, the communication unit 1120 is also used to receive first device information corresponding to the first WiFi information sent by the cloud server; if the first device information indicates that the second terminal device is in a meeting state, and the conference ID of the online conference that the second terminal device has joined is the same as the conference ID of the first online conference, it is determined that the second terminal device has joined the first online conference.

[0199] Optionally, the communication unit 1120 is also used to obtain Bluetooth broadcast information sent by the second terminal device; the processing unit 1110 is specifically used to: if the Bluetooth broadcast information indicates that the second terminal device located in the first area where the first terminal device is located is in a meeting state, and the conference ID of the online conference that the second terminal device has joined is the same as the conference ID of the first online conference, then it is determined that the second terminal device has joined the first online conference.

[0200] In another possible design, the membership device 1100 may be a module or chip applied to a cloud server. The membership device 1100 may be used to execute the steps or processes executed by the cloud server in the above-mentioned embodiments.

[0201] Specifically, the communication unit 1120 is used to receive first WiFi information sent by the first terminal device indicating that the first terminal device has been connected; the processing unit 1110 is used to determine pre-stored first device information corresponding to the first WiFi information, the first device information being used to indicate the device status of the second terminal device in the first area indicated by the first WiFi information, and the conference ID of the online conference that the second terminal device has joined when the device status is a joining state; the communication unit 1120 is also used to send the first device information to the first terminal device, and the first terminal device is used to close the audio acquisition module and the audio playback module of the first terminal device after determining that the second terminal device has joined the first online conference according to the first device information, and join the first online conference.

[0202] Optionally, the communication unit 1120 is also used to receive device information sent by a terminal device located in at least one area and an area identifier of the area where the terminal device is located, the device information including a device status of the terminal device and a conference ID of an online conference that the terminal device has joined when the device status is a joining status; the processing unit 1110 is also used to determine the mapping relationship between the WiFi information, the area identifier and the device information based on the area identifier and the pre-stored WiFi information corresponding to the area identifier.

[0203] Optionally, determining the pre-stored first device information corresponding to the first WiFi information includes: determining the first device information corresponding to the first WiFi information according to a mapping relationship among at least one pre-stored WiFi information, an area identifier, and device information.
