终端设备可以通过有线通信连接方式，或者无线连接通信连接方式，向服务端发送在步骤102中得到的第一配对信息。
服务端在接收到上述第一配对信息之后，可以基于第一配对信息确定目标多媒体会议终端。在确定了目标多媒体会议终端之后，建立目标多媒体会议终端与用户终端设备之间的通信连接。
终端设备可以安装用于控制多媒体会议终端的应用。在建立了上述通信连接之后，用户可以通过终端设备上安装的用于控制多媒体会议终端的应用来控制目标多媒体会议终端。例如，用户可以使用终端设备向目标多媒体会议终端发送启动多媒体会议的指令，目标多媒体会议终端在接收到用户终端设备的启动多媒体会议的指令后，开始进入多媒体会议模式，例如开始采集用户的多媒体数据信息，例如音频信息和/或视频信息，并将所采集的多媒体数据信息发送给多媒体会议服务端。用户还可以使用终端设备向目标多媒体会议终端发送调整多媒体会议的音视频参数的指令。目标多媒体会议终端可以根据用户发出的上述调整多媒体会议的音视频参数的指令，对多媒体会议的音视 频参数进行调整。
现有技术中，用户在使用多媒体会议终端进行多媒体会议时，需要使用与多媒体会议终端匹配的专用控制器控制多媒体会议终端，例如开启多媒体会议，对多媒体会议的音视频参数进行调整等。上述方式需要用户使用专用控制器来对多媒体会议终端进行控制。用户需要先找到专用控制器，再使用专用控制器控制多媒体会议终端。对用户而言，通过专用控制器控制多媒体会议终端的方式的便利性较差。
在本实施例中，通过获取第一近场通信信号；从第一近场通信信号中提取用于与多媒体会议终端配对的第一配对信息；将第一配对信息发送给服务端，以指示服务端基于第一配对信息确定目标多媒体会议终端以及建立目标多媒体会议终端与用户终端设备之间的通信连接。实现了用户使用用户终端设备即可控制多媒体会议终端，提高了用户控制多媒体会议终端的便利性。此外可以减少多媒体会议系统的整体成本。
需要说明的是，在一些应用场景中，用户还可以使用终端设备发出的包括控制指令的近场通信信号对目标多媒体会议设备执行预设控制操作。这里的预设控制操作例如可以包括开启多媒体会议、调整多媒体会议的音视频参数等。这里的近场通信信号例如可以包括超声波信号、蓝牙信号、Wi-Fi信号等。
在本实施例的一些可选的实现方式中，上述第一近场通信信号包括多媒体会议终端发出的超声波信号。超声波信号包括由多媒体会议终端根据服务端预先发送给多媒体会议终端的第二配对信息生成的第一配对信息。
在一些应用场景中，上述第一配对信息包括配对码。配对码可以包括字母、数字和/或符号。
服务端预先发给多媒体会议终端的第二配对信息中包括上述配对码。
上述第二配对信息可以每隔预设时间段进行一次更新。
由于第二配对信息所对应的配对码可以每隔预设时间段进行更新，可以确保所建立的通信连接的安全性。
在这些可选的实现方式中，上述超声波的频率在19KHZ～20KHZ之间。上述超声波的有效传输距离在5米以内。超声波可以携带上述第一配对信息。根据多媒体会议终端发出的超声波信号，可以有效区分不同的多媒体会议终端。
在这些的实现方式中，步骤101的获取第一近场通信信号，包括利用音频接收器接收上述超声波信号。
上述音频接收器可以是固定在用户的终端设备中的音频接收器，也可以是终端设备外接的音频接收器。
在这些可选的实现方式中，上述步骤103可以包括：将从超声波信号中提取的第一配对信息发送给服务端，以指示服务端基于第一配对信息以及第二配对信息确定目标多媒体会议终端以及建立目标多媒体会议终端与用户终端设备之间的通信连接。
上述通过使用超声波信号携带第一配对信息，终端设备可以从所获取的多媒体会议终端发出的超声波信号中提取出上述第一配对信息，并将所提取的第一配对信息发送给服务端。服务端将接收到的第一配对信息与预先发给多个多媒体会议终端的第二配对信息进行匹配，根据匹配结果确定从上述多个多媒体会议终端中确定出目标多媒体会议终端。这里多个多媒体会议终端各自对应的第二配对信息互不相同。
在这些可选的实现方式中，使用多媒体会议终端发出携带第一配对信息的超声波信号，终端设备获取上述超声波信号，并从超声波信号中提取出第一配对信息。终端设备将第一配对信息发送给服务端，以使服务端根据第一配对信息确定目标多媒体会议终端以及建立终端设备与多媒体会议终端的通信连接。由于上述超声波信号的有效传输距离较短，同一时刻仅有一个多媒体会议终端发出的超声波信号有效。从而通过超声波信号携带的第一配对信息确定目标多媒体会议终端时，可以提高所确定的目标多媒体会议终端的准确率。
在本实施例的一些可选的实现方式中，第一近场通信信号包括多媒体会议终端发出的蓝牙信号；以及在上述步骤102之前，信息交互法还包括如下步骤：
第一，根据获取到的蓝牙信号确定终端设备与多媒体会议终端之 间的距离。
第二，根据上述距离确定多媒体会议终端与终端设备是否位于同一会议室内。
第三，响应于根据上述距离确定多媒体会议终端与终端设备位于同一会议室内，从蓝牙信号中提取第一配对信息，第一配对信息包括多媒体会议终端的身份信息。
在这些可选的实现方式中，可以使用现有的基于蓝牙信号的室内定位技术，根据信号强度(RSSI-Received Signal Strength Indication)带入经验公式推算出大致的终端设备与发出上述蓝牙信号的多媒体会议终端的物理距离。然后根据上述物理距离确定多媒体会议终端与用户终端设备是否位于同一室内。
当确定了多媒体会议终端与用户终端设备位于同一室内(也即位于同一会议室内)，可以从蓝牙信号中提取第一配对信息。第一配对信息可以包括多媒体会议终端的身份信息。
在一些应用场景中，上述多媒体会议终端的身份信息可以包括多媒体会议终端的设备编码信息。
在另外一些应用场景中，上述多媒体会议终端的身份信息也可以包括服务端发送给多媒体会议终端的用于表示其身份的身份信息。
在这些应用场景中，服务端发送给多媒体会议终端的用于表示其身份的身份信息可以每隔预设时间段进行更新。
在这些可选的实现方式中，上述通过多媒体会议终端发出的蓝牙信号确定目标多媒体会议终端，可以保证所确定的多媒体会议终端的设备的准确性。
在本实施例的一些可选的实现方式中，上述第一近场通信信号包括Wi-Fi信号。上述步骤102可以包括：提取Wi-Fi信号所包括的Wi-Fi设备的身份信息，根据上述身份信息生成第一配对信息。以及上述步骤103包括：
将第一配对信息发送给服务端，以指示服务端根据第一配对信息所表征的Wi-Fi设备的身份信息与多个多媒体会议终端所在的网络环境中的Wi-Fi设备的身份信息确定目标多媒体会议终端。
这里的多媒体会议终端所在网络环境中的Wi-Fi设备的身份信息是由多媒体会议终端发送给服务端的。
Wi-Fi信号可以包括用户终端设备所在网络环境的Wi-Fi指纹，包括：Wi-Fi网络的SSIDs(Service Set Identifiers)和BSSIDs(basic SSIDs)。前者可以是Wi-Fi网络的名字，后者可以为48bit的数字(通常为AP的Mac地址)。多媒体会议终端会将自己读取的Wi-Fi指纹信息上传服务端，同时用户终端设备也会上传自己读取到的Wi-Fi指纹信息至服务端。当服务端发现二者相同，则可以为他们实现通信连接，完成配对。配对完成之后，终端设备就可以发送相关的控制命令给服务端，服务端转发控制命令到多媒体会议终端，从而完成多媒体会议终端的控制。
在这些可选的实现方式中，通过多媒体会议终端所在网络环境的Wi-Fi信号以及用户终端设备所在网络环境的Wi-Fi信号实现多媒体会议终端与用户终端设备之间的通信连接。Wi-Fi功能是目前电子设备普遍具有的功能，使用Wi-Fi功能实现多媒体会议终端与终端设备之间的通信连接，一方面便于用户对多媒体会议终端的控制，另一方面可以进一步减少多媒体会议系统的成本。
需要说明的是，可以结合不同的上述第一近场通信信号来确定用户终端设备所对应的目标多媒体会议终端。例如结合用户终端设备发送的包括多媒体会议终端发出的超声波信号以及用户终端设备所在网络环境的Wi-Fi的设备的身份信息来确定用户终端设备对应的目标多媒体会议终端。也即，第一配对信息中可以包括多媒体会议终端发出的超声波信号携带的配对码，以及终端设备所在网络环境的Wi-Fi设备的身份信息。服务端结合发送给各多媒体会议终端的配对码以及终端设备所在网络环境的Wi-Fi设备的身份信息确定目标多媒体会议终端。
在本实施例的一些可选的实现方式中，在将所获取的第一配对信息发送给服务端，指示服务端成功建立目标多媒体会议终端与用户终端设备之间的通信连接之后，信息交互方法还包括：
首先，每隔预设时间间隔重复获取第二近场通信信号。
其次，将所获取的第二近场通信信号发送给服务端，以使服务端根据第二近场通信信号确定是否保持通信连接。
这里的预设时间间隔可以为任意时间间隔，例如3分钟、5分钟等。
这里的第二近场通信信号至少包括以下之一：多媒体会议终端发出的超声波信号、多媒体会议终端发出的蓝牙信号、所在网络环境的Wi-Fi信号。
这里的第二近场通信信号可以是由目标多媒体会议终端向终端设备发出的近场通信信号。
这里第二近场通信信号可以包括目标多媒体会议终端的身份信息。终端设备将所接收到的第二近场通信信号发送给服务端。
在这些可选的实现方式中，服务端可以根据第二近场通信信号确定用户终端设备是否还对应上述目标多媒体会议终端。这里用户终端设备是否还对应上述目标多媒体会议终端，可以视为用户是否还在目标多媒体会议终端所对应的会议室中。
若是，则继续保持用户终端设备与上述目标多媒体会议终端之间的通信连接。否则，断开用户终端设备与上述目标多媒体会议终端之间的通信连接。
在这些应用场景中，用户终端设备需要每隔预设时间间隔获取附近的第二近场通信信号，并将第二近场通信信号发送给服务端，以使服务端确定是否保持用户终端设备与目标多媒体会议终端之间的通信连接。该方式使得用户可以不需要人为执行退出上述通信连接的操作，便可以退出用户终端设备与目标多媒体会议终端之间的通信连接，进一步为用户提供了便利性。此外，还可以保证多媒体与上述通信连接关联的多媒体会议信息的安全性。
在本实施例的一些可选的实现方式中，上述信息交互方法还包括：根据用户发出的操作指令，通过上述通信连接执行以下至少一者的操作：进入、退出多媒体会议的操作，对多媒体会议的音视频预设参数进行调整的操作，对会议内容进行预设处理的操作。
这里的进入、退出多媒体会议的操作可以包括：发起多媒体会议、加入多媒体会议、邀请参会人、离开会议等。
这里的对多媒体会议的预设参数进行调整的操作，包括：对多媒体会议的音频参数进行调整的操作(例如调整音量的大小)、对多媒体会议的视频参数进行调整的操作(例如调整视频的亮度、清晰度等)。
这里的对会议内容进行预设处理的操作，包括对会议内容进行录制等。
也即，用户可以通过终端设备控制多媒体会议终端，用户终端设备可以替代多媒体会议终端对应的控制设备。
请继续参考图2，其示出了根据本公开的信息交互方法的一个实施例的流程，例如可以应用于服务端。如图2所示，该信息交互方法，包括以下步骤：
步骤201，接收终端设备发送的用于配对的第一配对信息。
这里的第一配对信息由终端设备从获取的第一近场通信信号中提取。上述第一配对信息可以包括字母、数字和/或符号等。
上述第一近场通信信号至少包括以下之一：多媒体会议终端发出的超声波信号、多媒体会议终端发出的蓝牙信号、所在网络环境的Wi-Fi信号。

这里的多媒体会议终端的信息可以为多个候选多媒体会议终端各自对应的信息。
步骤202，将第一配对信息与多媒体会议终端的信息进行匹配。
步骤203，根据匹配的结果确定目标多媒体会议终端。
步骤204，建立目标多媒体会议终端与终端设备之间的通信连接。

本实施例提供的信息交互方法，通过接收终端设备发送的第一配对信息，将第一配对信息与多媒体会议终端的信息进行匹配；根据匹配结果确定目标多媒体会议终端以及建立目标多媒体会议终端与终端设备之间的通信连接，从而用户不必使用多媒体会议终端的控制终端便可控制多媒体会议终端。提高了用户控制多媒体会议终端的便利性。 此外可以减少多媒体会议系统的整体成本。
在本实施例的一些可选的实现方式中，上述第一近场通信信号包括多媒体会议终端发出的超声波信号；第一配对信息由多媒体会议终端根据服务端预先发送给多媒体会议终端的第二配对信息生成。
这里多媒体会议终端的信息可以为多个候选多媒体会议终端各自对应的第二配对信息。
服务端发送给候选多媒体会议终端的第二配对信息可以每隔预设时间段进行一次更新。预设时间段可以为3分钟、5分钟。
在一些应用场景中，在多媒体会议终端未与用户终端设备建立通信连接的状态下，服务端可以每隔预设时间段向多媒体会议终端发送一次更新的第二配对信息。在多媒体会议终端与用户终端设备建立通信连接之后，且上述通信连接保持期间，可以不向多媒体会议终端发送更新的第二配对信息。直至上述通信连接断开，再向多媒体会议终端发送更新的第二配对信息。
第二配对信息可以包括预设配对码。配对码可以包括字母、数字和符号。
在这些可选的实现方式中，上述步骤202可以包括：将第一配对信息与多个候选多媒体会议终端各自对应的第二配对信息进行匹配；以及
上述步骤203可以包括：将与第一配对信息匹配的第二配对信息所对应的候选多媒体会议终端，确定为目标多媒体会议终端。
在这些可选的实现方式中，使用多媒体会议终端发出携带第一配对信息的超声波信号，终端设备获取上述超声波信号，并从超声波信号中提取出第一配对信息。终端设备将第一配对信息发送给服务端，以使服务端根据第一配对信息确定目标多媒体会议终端以及建立终端设备与多媒体会议终端的通信连接。由于上述超声波信号的有效传输距离较短，同一时刻仅有一个多媒体会议终端发出的超声波信号有效。从而通过超声波信号携带的第一配对信息确定目标多媒体会议终端时，可以提高所确定的目标多媒体会议终端的准确率。
在本实施例的一些可选的实现方式中，第一配对信息包括多媒体 会议终端的身份信息。多媒体会议终端的身份信息由终端设备根据从多媒体会议终端的蓝牙设备发送的蓝牙信号中确定。
在这些可选的实现方式中，上述步骤202可以包括：将第一配对信息所表征的多媒体会议终端身份信息与多个候选多媒体会议终端各自对应的身份信息进行匹配。
这里的多媒体会议终端的身份信息可以是多媒体会议终端的设备编号。还可以是服务端发送的用于区别不同多媒体会议终端的身份标识信息。
服务端可以将用户终端设备发送的第一配对信息所表征的多媒体会议终端身份信息与多个候选多媒体会议终端各自对应的身份信息进行匹配。将与用户终端设备发送的第一配对信息所表征的多媒体会议终端身份信息匹配的候选多媒体会议终端确定为目标多媒体会议终端。
服务端可以建立目标多媒体会议终端与用户终端设备之间的通信连接。从而实现使用用户终端设备控制上述目标多媒体会议终端。
在本实施例的一些可选的实现方式中，第一配对信息可以包括多媒体会议终端所在网络环境的Wi-Fi设备的身份信息。上述步骤202可以包括：将Wi-Fi设备的身份信息与预设多个候选多媒体会议终端各自对应的Wi-Fi设备的身份信息进行匹配。
这里的Wi-Fi设备的身份信息可以是发出Wi-Fi热点信号的电子设备。
Wi-Fi信号可以包括用户终端设备所在网络环境的Wi-Fi指纹，包括：Wi-Fi网络的SSIDs(Service Set Identifiers)和BSSIDs(basic SSIDs)。前者可以是Wi-Fi网络的名字，后者可以为48bit的数字(通常为AP的Mac地址)。多媒体会议终端会将自己读取的Wi-Fi指纹信息上传服务端，同时用户终端设备也会上传自己读取到的Wi-Fi指纹信息至服务端。当服务端发现二者相同，则可以为他们实现通信连接，完成配对。配对完成之后，终端设备就可以发送相关的控制命令给云端，服务端转发控制命令到多媒体会议终端，从而完成多媒体会议终端的控制。
在这些可选的实现方式中，通过多媒体会议终端所在网络环境的 Wi-Fi信号以及用户终端设备所在网络环境的Wi-Fi信号实现多媒体会议终端与用户终端设备之间的通信连接。Wi-Fi功能是目前电子设备普遍具有的功能，使用Wi-Fi功能实现多媒体会议终端与终端设备之间的通信连接，一方面便于用户对多媒体会议终端的控制，另一方面可以进一步减少多媒体会议系统的成本。
在本实施例的一些可选的实现方式中，信息交互方法还可以包括：在通信连接锁定状态下，拒绝接受新的第一配对信息。
这里的通信连接锁定状态基于所接收的用户发出的锁定建立通信连接的通信连接锁定请求触发。当接收到用户发出的锁定建立通信连接的通信连接锁定请求后，可以将建立目标多媒体会议终端与用户终端设备之间的通信连接功能置为通信连接锁定状态。
上述通信连接锁定请求可以是用户通过终端设备发出的，也可以是用户通过多媒体会议终端的控制设备发出的。
服务端可以在接收到用户的锁定请求之后，在锁定状态保持期间可以拒绝接收新的第一配对信息。实践中，服务端在接收到用户的上述锁定请求之后，可以确定锁定请求是否可以生效。服务端在确定锁定请求生效后，将建立目标多媒体会议终端与用户终端设备之间的通信连接功能置为通信连接锁定状态。在上述通信连接锁定状态保持期间，服务端不再接收新的第一配对信息。
这里新的第一配对信息可以为在通信连接锁定状态期间，其他用户通过其使用的终端设备向服务端发送的、从获取到的近场通信信号中提取的第一配对信息。
上述通信连接锁定状态保持期间可以为用户发出锁定请求到接收到用户发出的解锁请求之间的时间段。上述解锁请求为解锁通信连接状态的解锁请求。
进一步可选地，信息交互方法还可以包括：响应于接收到用户发出的用于解锁通信连接锁定状态的解锁请求，重新接收新的第一配对信息。
在接收到用户发出的解锁请求之后，服务端可以将上述通信连接锁定状态重置为无效，重新开始接收新的第一配对信息。
在这些可选的实现方式中，在接收到锁定请求之前，已经建立的目标多媒体会议终端与用户终端设备之间的通信连接保持有效。
在这些可选的实现方式中，可以根据用户的通信连接锁定请求、解锁请求，确定是否接收其他终端设备发出的第一配对信息。从而可以提高目标多媒体会议终端当前的多媒体会议的安全性。
在本实施例的一些可选的实现方式中，信息交互方法还包括：在目标多媒体会议终端的远程控制锁定状态下，拒绝用户通过已建立的通信连接对目标多媒体会议终端执行远程控制操作。
这里的远程控制锁定状态基于所接收的用户发出的锁定对目标多媒体会议终端进行远程控制的控制锁定请求触发。
在上述远程控制锁定状态下，当接收到用户发出的锁定远程控制的控制锁定请求，服务端拒绝用户通过已建立的通信连接对目标多媒体会议终端执行远程控制操作。
上述控制锁定请求可以是用户通过终端设备发出的，也可以是用户通过多媒体会议终端的控制设备发出的。
在一个大型的会议场所内，若多人控制同一个设备，会存在竞争关系。或者在一些严肃的会议场景，希望限制参会者对设备的远程操作。可以通过上述控制锁定请求来控制用户使用终端设备通过上述通信连接对目标多媒体会议终端执行远程操作。
上述远程操作例如可以包括调整多媒体会议的音量、调整多媒体会议的视图、调整多媒体会议的视频亮度、清晰度等。
在这些可选的实现方式中，通过控制锁定请求锁定用户通过终端设备对目标多媒体会议终端执行的远程控制操作，有利于避免多人远程控制目标多媒体会议终端发生的竞争现象。
在本实施例的一些可选的实现方式中，信息交互方法还包括：响应于当前时刻满足断开通信连接的条件，断开上述通信连接。
上述断开通信连接的条件包括以下之一：
当前时刻与上一次获取第二近场通信信号的时刻之间的时间间隔大于预设第二时间阈值；根据蓝牙信号定位方式确定终端设备不在目标会议室终端设备所在的会议室内；第一配对信息中的Wi-Fi信号表 征的Wi-Fi设备的身份信息与会议室终端的Wi-Fi信号表征的Wi-Fi设备身份信息不匹配；接收用户发送的解除通信连接的解除请求。
其中，第二近场通信信号由用户终端设备每隔预设时间间隔重复获取并发送给服务端，服务端根据上述第二近场通信信号确定是否保持通信连接。
这里用户发送的解除通信连接的解除请求，可以是用户用于请求解除自己使用的终端设备与目标多媒体终端的通信连接的解除请求。也可以是具有预设权限的用户发送的用于解除其他用户的终端设备与目标多媒体会议终端的通信连接的解除请求。
服务端根据(1)当前时刻与上一次获取第二近场通信信号的时刻之间的时间间隔大于预设第二时间阈值，断开上述通信连接；(2)根据蓝牙信号定位方式确定终端设备不在目标会议室终端设备所在的会议室内，断开上述通信连接；(3)第一配对信息中的Wi-Fi信号表征的Wi-Fi设备的身份信息与会议室终端的Wi-Fi信号表征的Wi-Fi设备身份信息不匹配时，断开目标多媒体会议终端与终端设备之间的通信连接。以上三种实现断开上述通信连接的方式，可以不需要用户的操作实现通信连接之间的断开，一方面可以减少用户的操作。另一方面可以保证多媒体会议内容的安全性。
