具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供一种会议级联方法，如图1所示，示出了本发明会议级联方法第一实施例的流程示意图，所述会议级联方法包括：
S10、在接收到主会议发送的第一级联请求时，根据所述第一级联请求设置至少两个端点，其中，设置的端点组成一个会议桥；
所述主会议是指主动发起级联其他会议的会议，在会议服务器上以会议号来唯一标识一个会议；所述主会议所要级联的会议可以为在同一会议服务器上的会议，也可以为不在同一会议服务器上的会议，不同会议服务器上会议通信采用的信令格式可以不同。所述第一级联请求是指所述主会议通过其所属的会议服务器向会议桥服务器发送的请求。所述会议桥服务器是指能够创建并管理会议桥的服务器，其可以为独立的物理服务器，也可以部署在会议服务器所在的物理服务器上。
例如，主会议（会议A）的用户想要级联其他分会议（会议B、会议C）时，用户通过会议A的终端向会议A所在的会议服务器发出级联指令，会议A所在会议服务器接收到所述级联指令后，根据所述级联指令中包含的分会议的会议号向会议桥服务器发送第一级联请求，其中，所述第一级联请求包括各个分会议的信息，如会议B、会议C各自的会议号。所述会议桥服务器接收会议服务器上会议A发送的所述第一级联请求，根据所述第一级联请求设置所需个数的端点，从而由设置的端点组成一个与主会议关联的会议桥，其中，一个会议桥中包含的端点至少有两个（在主会议只级联一个分会议时，会议桥中端点个数为两个）。
会议桥中的端点可以为根据实际需求动态创建，也可以为预先在会议桥服务器中创建好，然后根据第一级联请求中主会议级联分会议的个数需求，在需要将一个会议与一个端点进行级联时，从预先创建好的端点池中选取一个端点进而级联。在从端点池中选取一个端点时，如果当前端点已被占用，则从端点池中选取其他未被占用的端点。
S20、将所述主会议和所述第一级联请求中包含的各个分会议，以一一对应的方式与所述会议桥的各个端点进行级联，以及将各个端点进行两两级联；
假设为所述会议桥设置的未被占用的端点为端点D、端点E、端点F，则其中一种级联结果为会议A级联端点D、会议B级联端点E、会议C级联端点F。还可以为其他的级联结果，如会议A级联端点F、会议B级联端点D、会议C级联端点E，或者会议A级联端点E、会议B级联端点F、会议C级联端点D，等等，只要满足与同一个会议桥关联的各个会议中，一个会议与会议桥中一个端点一一对应级联即可。
本实施例中，所述会议桥中各个端点之间通过网络套接字进行通信，从而实现端点与端点间的级联；在端点与会议进行级联时，所述会议桥中的端点以会议成员的方式加入相应的会议。端点与端点间的级联可以在会议与端点进行级联的同时，或者在会议与端点进行级联之前或之后进行。
S30、将级联后的端点各自接收到的所有媒体数据，按照与端点级联的会议所支持的信令格式处理后发送到所述与端点级联的会议。
级联后的每个端点能够实时接收由级联后的其他端点发送的媒体数据，例如，端点E能够接收由端点D和端点F各自发送的媒体数据，端点E将接收到的端点D发送的媒体数据和端点F发送的媒体数据分别进行解析，并将解析后的媒体数据经过进一步的数据处理后，按照与端点E级联的会议所采用的信令格式，将处理后的数据发送到与端点E级联的会议。
本发明提出的会议级联方法，通过采用虚拟会议桥中的端点，以及按照与端点级联的会议所支持的信令格式，将端点接收到的所有媒体数据处理后发送到与端点级联的会议，实现了具有不同信令格式的多个会议的级联，提高了不同会议系统之间信令的兼容性。
进一步地，参照图2，基于第一实施例提出本发明会议级联方法第二实施例，在本实施例中，上述步骤S10包括：
S11、在接收到主会议发送的第一级联请求时，获取所述第一级联请求中包含所述主会议所要级联的分会议的个数n；
S12、创建n+1个虚拟的端点，其中，创建的n+1个端点组成一个会议桥。
根据所述第一级联请求中各个分会议的会议号，统计获得分会议的个数n；创建n+1个虚拟的端点，其中，以端点号来唯一标识一个端点，所创建的n+1个端点组成一个与所述主会议关联的会议桥。例如，会议A发送的第一级联请求中包括会议B、会议C，则n的值为2，与会议A关联的会议桥中端点个数为3。由于主会议至少能够和一个分会议级联，因而会议桥中端点的个数至少为两个。
本发明提出的会议级联方法，根据主会议的实际需求创建需求个数的端点，并由创建的端点组成一个与主会议关联的会议桥，方法简单易于实现，端点的设置方式也较为灵活。
进一步地，参照图3，基于第二实施例提出本发明会议级联方法第三实施例，在本实施例中，所述第一级联请求包括所述分会议的会议号；上述步骤S20包括：
S21、从所述会议桥中选择一个端点与所述主会议进行级联；
由于所述会议桥中各个端点均为新创建的，各个端点均未被占用，因而，可以从所述会议桥中随机选择一个端点与所述主会议进行级联。
S22、根据所述第一级联请求中包含的所述分会议的会议号，通过与所述主会议进行级联的端点向所述会议桥中其他所有端点分别发送包含唯一会议号的第二级联请求，并将所述会议桥中所有的端点两两级联；
可以在所述会议桥中所有的端点创建完成时，将两两端点相互级联，也可以在主会议和一个端点级联后，由与所述主会议级联的端点分别向所述会议桥中其他各个端点发送第二级联请求时，通过网络套接字建立通信从而实现将所述会议桥中两两端点进行相互级联，其中，一个第二级联请求中仅包含一个会议号，且不同的第二级联请求中的会议号不同。例如，与会议A级联的端点D，向所述会议桥中端点E发送包含会议B的会议号的第二级联请求，向所述会议桥中端点F发送包含会议C的会议号的另一第二级联请求。
S23、通过接收到第二级联请求的各个端点，分别与第二级联请求中包含的分会议进行级联。
例如，接收到第二级联请求的端点E，根据其接收的第二级联请求中包含的会议B的会议号，与会议B进行级联；接收到另一第二级联请求的端点F，根据其接收的第二级联请求中包含的会议C的会议号，与会议C进行级联。对于分会议的个数为其他值（大于或等于2）的情况，级联方法以此类推。
参照图4，由于会议A与端点D级联，端点D与端点E、端点F两两相互级联，端点E与会议B级联，端点F与会议C级联，从而实现作为主会议的会议A与作为分会议的会议B、会议C之间的两两互通，此时的每一个会议均能共享其他会议中实时的会议内容。
本发明提出的会议级联方法，通过虚拟的会议桥中两两级联的端点，将多个会议间接级联起来，使得不同会议之间能够实时共享其他会议上的会议内容，提高了开会的效率。
进一步地，参照图5，基于第一实施例提出本发明会议级联方法第四实施例，在本实施例中，上述步骤S30包括：
S31、对于级联后的每个端点，将当前端点接收到的由所述会议桥中其他端点发送的所有的媒体数据进行解析，其中，在所述会议桥中，由一个端点发出的包含音频数据和视频数据的媒体数据，被发送到所述会议桥中其他所有的端点；
级联分会议后的各个会议，通过各自级联的端点接收由所述会议桥中其他端点发送的媒体数据；一个端点在接收到来自同一会议桥中其他端点发送的媒体数据时，分别对各个媒体数据进行解析。
S32、从解析后的媒体数据中提取出所有的音频数据进行混音处理，同时，从解析后的媒体数据中按照会议号提取出视频数据；
S33、将混音处理后的音频数据和按照会议号提取出的视频数据，按照与当前端点级联的会议所支持的信令格式发送到与当前端点级联的会议。
例如，对于与会议B级联的端点E接收到的由端点D、端点F各自发送的媒体数据，将从端点D发送的媒体数据中提取出的音频数据与从端点F发送的媒体数据中提取出的音频数据进行混音处理，从端点D发送的媒体数据中提取出视频数据，从端点F发送的媒体数据中提取出视频数据，不同的视频数据用其所属的会议号标识；之后，端点E将混音处理后的音频数据、会议A的会议号标识的视频数据、会议C的会议号标识的视频数据，按照会议B采用的信令格式发送到会议B所在的会议服务器；会议B所在的会议服务器接收上述音频数据和视频数据后，将其发送给归属于会议B的一个或多个终端进行播放。
本发明提出的会议级联方法，针对级联后的每个端点，对端点接收到的媒体数据进行解析处理、数据分类型处理等操作，支持在采用不同信令格式的会议之间共享会议内容。
本发明还提供一种会议级联装置，如图6所示，示出了本发明会议级联装置第一实施例的功能模块示意图，所示会议级联装置包括：
创建模块100，用于在接收到主会议发送的第一级联请求时，根据所述第一级联请求设置至少两个端点，其中，设置的端点组成一个会议桥；
所述主会议是指主动发起级联其他会议的会议，在会议服务器上以会议号来唯一标识一个会议；所述主会议所要级联的会议可以为在同一会议服务器上的会议，也可以为不在同一会议服务器上的会议，不同会议服务器上会议通信采用的信令格式可以不同。所述第一级联请求是指所述主会议通过其所属的会议服务器向会议桥服务器发送的请求。所述会议桥服务器是指能够创建并管理会议桥的服务器，其可以为独立的物理服务器，也可以部署在会议服务器所在的物理服务器上。
例如，主会议（会议A）的用户想要级联其他分会议（会议B、会议C）时，用户通过会议A的终端向会议A所在的会议服务器发出级联指令，会议A所在会议服务器接收到所述级联指令后，根据所述级联指令中包含的分会议的会议号向会议桥服务器发送第一级联请求，其中，所述第一级联请求包括各个分会议的信息，如会议B、会议C各自的会议号。所述会议桥服务器的创建模块100接收会议服务器上会议A发送的所述第一级联请求，根据所述第一级联请求设置所需个数的端点，从而由设置的端点组成一个与主会议关联的会议桥，其中，一个会议桥中包含的端点至少有两个（在主会议只级联一个分会议时，会议桥中端点个数为两个）。
会议桥中的端点可以为根据实际需求动态创建，也可以为预先在会议桥服务器中创建好，然后根据第一级联请求中主会议级联分会议的个数需求，在需要将一个会议与一个端点进行级联时，从预先创建好的端点池中选取一个端点进而级联。在从端点池中选取一个端点时，如果当前端点已被占用，则从端点池中选取其他未被占用的端点。
级联模块200，用于将所述主会议和所述第一级联请求中包含的各个分会议，以一一对应的方式与所述会议桥的各个端点进行级联，以及将各个端点进行两两级联；
假设为所述会议桥设置的未被占用的端点为端点D、端点E、端点F，则其中一种级联结果为会议A级联端点D、会议B级联端点E、会议C级联端点F。还可以为其他的级联结果，如会议A级联端点F、会议B级联端点D、会议C级联端点E，或者会议A级联端点E、会议B级联端点F、会议C级联端点D，等等，只要满足与同一个会议桥关联的各个会议中，一个会议与会议桥中一个端点一一对应级联即可。
本实施例所述会议级联装置中，所述会议桥中的端点之间通过网络套接字进行通信，从而实现端点与端点间的级联；在端点与会议进行级联时，所述会议桥中的端点以会议成员的方式加入相应的会议。端点与端点间的级联可以在会议与端点进行级联的同时，或者在会议与端点进行级联之前或之后进行。
处理模块300，用于将级联后的端点各自接收到的所有媒体数据，按照与端点级联的会议所支持的信令格式处理后发送到所述与端点级联的会议。
级联后的每个端点能够实时接收由级联后的其他端点发送的媒体数据，例如，端点E能够接收由端点D和端点F各自发送的媒体数据，在所述处理模块300中，端点E将接收到的端点D发送的媒体数据和端点F发送的媒体数据分别进行解析，并将解析后的媒体数据经过进一步的数据处理后，按照与端点E级联的会议所采用的信令格式，将处理后的数据发送到与端点E级联的会议。
本发明提出的会议级联装置，通过采用虚拟会议桥中的端点，以及按照与端点级联的会议所支持的信令格式，将端点接收到的所有媒体数据处理后发送到与端点级联的会议，实现了具有不同信令格式的多个会议的级联，提高了不同会议系统之间信令的兼容性。
进一步地，参照图7，基于上述第一实施例提出本发明会议级联装置第二实施例，在本实施例中，所述创建模100包括：

本发明提出的会议级联装置，根据主会议的实际需求创建需求个数的端点，并由创建的端点组成一个与主会议关联的会议桥，方法简单易于实现，端点的设置方式也较为灵活。

参照图4，由于会议A与端点D级联，端点D与端点E、端点F两两相互级联，端点E与会议B级联，端点F与会议C级联，从而实现作为主会议的会议A与作为分会议的会议B、会议C之间的两两互通，此时的每一个会议均能共享其他会议中实时的会议内容。
