具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
下面首先对本发明中涉及的一些专业术语进行解释，如下：
在级联会议召开的过程中往往会涉及到MCU、业务管理系统、媒体处理模块、MC模块、协议栈等，其中，
MCU：多点控制单元，Microcontroller Unit，简称为MCU，设置为提供实现和在会用户终端(包括手机、电话、PC、终端等)音频视频以及数据的交互；
业务管理系统：设置为提供操作界面，管理级联会议业务，在应用于会议电视系统召开级联会议时为会议电视业务管理系统；
媒体处理模块：设置为媒体的编解码处理；
多点控制应用服务器(MultiPoint Control Application Server，简称为MC)模块，设置为多点呼叫管理和会议控制的模块；
协议栈，设置为与终端或者其他MCU之间进行数据交互，如呼叫接入、注册等。
在本实施例中提供了一种会议级联方法，图2是根据本发明第一实施例的会议级联方法的流程图，如图2所示，该流程包括如下步骤S102至步骤S106：
步骤S102，第一MCU获取第二MCU生成的级联会议请求。
步骤S104，第一MCU判断级联会议请求是否满足预设格式。
步骤S106，在判断到级联会议请求满足预设格式的情况下，第一MCU根据级联会议请求中携带的第一MCU的级联会议号码加入第二MCU发起的级联会议。
在该实施例中，第二MCU首先向第一MCU发送级联会议请求，第一MCU可包括多个第一MCU。第一MCU通过判断该级联会议请求是否满足预设格式，来确定该级联会议请求是否设置为请求第一MCU加入第二MCU发起的级联会议。当第一MCU包括多个第一MCU时，第二MCU只需一次性向该多个第一MCU发送满足预设格式的级联会议请求，即可使该多个第一MCU加入级联会议。
该实施例可以作为会议电视系统召开级联会议的方法，通过在各个MCU的业务管理系统的页面上配置级联口，其中，级联口类型满足预设格式；在各个MCU的业务管理系统的页面上配置会议草稿，指定各组会议的级联模式(如主会议、从会议、三会议、多级一级会议等)。当级联会议中的任何一方发起级联会议请求，则对端MCU获取该级联会议请求，并判断该级联会议请求是否满足预设格式。在判断出级联会议请求满足预设格式的情况下，对端MCU将添加端口或者级联口到该级联会议中，以加入该级联会议。
通过上述步骤，第一MCU获取第二MCU生成的级联会议请求；第一MCU判断级联会议请求是否满足预设格式；在判断到级联会议请求满足预设格式的情况下，第一MCU根据级联会议请求中携带的第一MCU的级联会议号码加入第二MCU发起的级联会议，解决了在召开包含多个MCU的级联会议时操作较为繁琐的问题，进而在判断到级联会议请求满足预设格式的情况下，第一MCU根据级联会议请求中携带的第一MCU的级联会议号码加入第二MCU发起的级联会议，实现了召开级联会议中的一个会议，即可自动把余下的所有会议都自动召开起来，达到了提高召开级联会议的便利性的效果。
优选地，预设格式包括：第一字段和第二字段，其中，第一字段设置为指示第一MCU的地址，第二字段设置为指示第一MCU的级联会议号码。
在该优选实施例中，级联会议请求的预设格式采用第一MCU的地址+第一MCU的级联会议号码的格式，也即第一MCU的地址+第一MCU的级联会议号码作为级联会议请求的一个标识信息。通过识别级联会议请求中是否包括第一MCU的地址和第一MCU的级联会议号码，来确定是否加入第二MCU发起的级联会议。第一MCU的地址可以为第一MCU的IP地址。第一MCU的级联会议号码为第一MCU加入该级联会议的会议号码。
需要说明的是，可预先在每个可能参与级联会议的MCU中配置与之级联的级联会议号码，以及与之级联的MCU的地址。在任何一个MCU需要发起级联会议时，只需向其他的MCU发送预设格式的级联会议请求，即可召开包含多个MCU的级联会议。具体来说，可以在各个MCU的业务管理系统的页面配置级联口，级联口类型选择“第一MCU的地址+第一MCU的级联会议号码”的形式。另外，可通过各业务管理系统的页面配置会议草稿，指定各组会议的级联模式(如主会议、从会议、三会议、多级一级会议等)，添加终端和级联口，保持个MCU的级联口的能力一致。
优选地，在判断到级联会议请求满足预设格式的情况下，第一MCU根据级联会议请求中携带的第一MCU的级联会议号码加入第二MCU发起的级联会议包括：第一MCU判断级联会议号码对应的会议是否处于召开状态；在判断到会议处于召开状态的情况下，第一MCU在 第一MCU的地址簿中查找与级联会议号码对应的终端或者级联口；第一MCU将终端或者级联口添加至级联会议号码对应的会议中，以加入第二MCU发起的级联会议。
优选地，在判断到会议处于未召开状态的情况下，该方法还包括：第一MCU检测第一MCU的会议草稿箱中是否存在级联会议号码对应的会议；在检测到会议草稿箱中存在级联会议号码对应的会议的情况下，第一MCU召开级联会议号码对应的会议。
优选地，在第一MCU获取第二MCU生成的级联会议请求之前，该方法还包括：在第一MCU的地址簿中存储与级联会议号码对应的终端或者级联口；在第一MCU的会议草稿箱中存储与级联会议号码对应的会议。
在该实施例中，预先在参加级联会议的各个MCU中配置与级联会议号码对应的终端或者级联口，在会议草稿箱中存储与级联会议号码对应的会议。当收到级联会议的任何一方发起的级联会议请求时，判断级联会议请求是否满足预设格式，如与之级联的MCU的地址和级联会议号码，在判断出满足该预设格式的情况下，在地址簿中查找对应的终端或者级联口，并将其添加到会议中，或者在草稿箱中查找该会议，并召开该会议。
可选地，在检测到会议草稿箱中不存在级联会议号码对应的会议的情况下，该方法还包括：第一MCU拒绝召开级联会议请求对应的会议。
在该实施例中，在判断出级联会议号码对应的会议处于未召开的状态，并且在会议草稿箱中未检测到级联会议号码对应的会议，则拒绝该级联会议请求，或者决绝召开该级联会议请求对应的会议。
可选地，在第一MCU获取第二MCU生成的级联会议请求之前，该方法还包括：第二MCU中的协议栈提取级联会议请求中携带的第二MCU的地址；第二MCU中的协议栈按照第一MCU的地址向第一MCU中的协议栈发送级联会议请求。
在该实施例中，在级联会议的任何一方生成级联会议请求之后，该方将利用协议栈提取级联会议请求中携带的对端MCU的地址，并根据该地址呼叫对端MCU的协议栈，以将级联会议请求发送至对端MCU的协议栈。这里，通过MCU中的协议栈实现MCU之间的数据交互(呼入接入)。
可选地，第一MCU获取第二MCU生成的级联会议请求包括：第一MCU中的协议栈接收级联会议请求；第一MCU中的协议栈将级联会议请求透传至第一MCU中的MC模块，其中，MC模块将级联会议请求透传至第一MCU的业务管理系统，业务管理系统从级联会议请求中提取级联会议号码。
在该实施例中，对端MCU的协议栈接收到级联会议请求后，将该级联会议请求透传至MC模块，MC模块再将其透传至业务管理系统，业务管理系统对级联会议请求进行分析，判断其是否满足预设格式，如果判断出满足预设格式，则提取其包含的级联会议号码。级联会议号码将提取的级联会议号码重新透传至该端的MC模块，MC模块根据该级联会议号码召开会议并处理能力交互流程；MC模块将级联会议号码透传至该端的协议栈，并告知能力交互后 交互出的媒体端口，协议栈呼叫媒体终端；该端的媒体处理模块与媒体终端实现互通。
图3是根据本发明第二实施例的会议级联方法的流程图。图3可作为图2所示实施例的一种优选的实施方式。如图3所示，该方法包括如下的步骤S202至步骤S220：
步骤S202，环境准备。
预先在参加级联会议的各个MCU中配置与级联会议号码对应的终端或者级联口，在会议草稿箱中存储与级联会议号码对应的会议。其中，级联口的类型配置为预设格式，即与之级联的级联会议号码和与之级联的MCU的IP地址。
步骤S204，召开会议，对端收到呼叫。
在一方发起级联会议请求后，按照IP地址将级联会议请求发送至对端MCU，也即对端收到呼叫。
步骤S206，根据呼叫的会议标识查找会议。
对端MCU判断接收到的级联会议请求是否满足预设格式，也即判断其是否满足预先配置的参与级联会议的级联口格式。如果满足该预设格式，则可以进一步判断其否要参与该级联会议。
步骤S208，判断会议是否召开。如果判断出会议已经召开，则执行步骤S210；如果判断出会议未召开，则执行步骤S214。
步骤S210，在地址簿中查找与该呼叫相同的终端或者级联口。
步骤S212，添加该终端或者级联口，并接入呼叫。
步骤S214，在草稿箱中查找该会议。
业务管理系统判断该会议是否正在召开，如果判断出会议已经召开，则根据级联会议请求中包含的级联会议号码在业务管理系统的地址簿中查找与该级联会议请求相同的终端或者级联口，并将该终端或者级联口添加至该会议中。如果判断出会议尚未召开，则在草稿箱中查找该会议，也即判断该会议是否为预先计划召开的会议。
步骤S216，判断是否查找到该会议。如果判断出查找到该会议，则执行步骤S218；如果判断出未查找到该会议，则执行步骤S220。
步骤S218，召开会议。
步骤S220，拒绝该呼叫。
如果在草稿箱中查找到该会议，则召开该次级联会议；如果未在草稿箱中查找到该会议，则拒绝该级联会议请求。
根据该实施例的会议级联方法，预先在各个MCU端配置与级联会议号码对应的终端或者 级联口，在会议草稿箱中存储与级联会议号码对应的会议，当收到级联会议的任何一方发起的级联会议请求时，判断级联会议请求是否满足预设格式，在判断出满足该预设格式的情况下，在地址簿中查找对应的终端或者级联口，并将其添加到会议中，或者在草稿箱中查找该会议，并召开该会议，解决了在召开包含多个MCU的级联会议时操作较为繁琐的问题，实现了召开级联会议中的一个会议，即可自动把余下的所有会议都自动召开起来，达到了提高召开级联会议的便利性的效果。
图4是根据本发明第三实施例的会议级联方法中MCU之间进行通信的示意图。图4可作为图2所示实施例的一种优选的实施方式。如图4所示，MCU3(在图中未示出)包括业务管理系统11、MC模块12、媒体处理模块13、协议栈14；MCU4(在图中未示出)包括务管理系统20、MC模块19、媒体处理模块16、协议栈17。终端15是MCU3用于召开会议的终端，终端18是MCU4用于召开会议的终端。图2所示实施例中的第一MCU可以通过该实施例中的MCU4来实现，图2所示实施例中的第二MCU可以通过该实施例中的MCU3来实现。
具体来说，MCU3向MCU4发出级联会议请求，MCU3中的业务管理系统11提取级联会议请求中的MCU2的IP地址，并基于该IP地址通过协议栈14呼叫MCU2的协议栈17，该IP地址的MCU4收到呼叫后，把级联会议请求透传给MC模块19，MC模块19收到协议栈17透传的级联会议请求，继续将其透传至业务管理系统20。业务管理系统20收到从底层透传的级联会议请求后，业务管理系统20会从该级联会议请求中提取级联会议号码，并召开该会议。MC模块19收到召开会议请求，召开会议并处理能力交互流程。协议栈17收到召开会议请求，呼叫终端18。MC模块19告知能力交互后交互出的媒体端口。媒体处理模块16与终端18互通。
根据该实施例的会议级联方法，不需要额外增加其它模块，只需要在业务管理系统、MC模块上等新增处理该级联会议流程的消息，简化了召开包含多个MCU的级联会议的过程。该方法可应用于会议电视系统召开级联会议，特别是现网中应用多级级联会议、一主20从会议类型的场景，可方便会议组织者召开会议。
综上所述，本发明通过在MCU的业务管理系统上把级联口的呼叫模式配置为“级联会议号码+与之级联的MCU的地址”，达到了召开级联会议中的一个会议，即可自动把余下的所有会议都召开起来的效果。通过本发明，会议管理或者组织者可以很方便地召开级联会议。
