实施例三：
图 3示出了本发明实施例三提供的远程会议控制方法的实现流程，该方法 过程详述如下：
1、 多点控制单元 MCU向入会终端发送中断会议指示信息。
本实施例中的 MCU根据定义的扩展的会议控制信息， 向各入会终端发送
中断或恢复的会议指示信息来实现会议的中断或恢复。其中， 定义的扩展的会 议控制信息（企业标准会控（IDO )协议的信息） 包括但不局限于如表一所示 部分：
MCU发送中断请求信息， MCU在接收到具有中断权限的入会终端发送的中断 会议请求信息后， 向所有或者部分入会终端发送中断会议指示信息 （如图 2 所示） 。 需要说明的是，
其中
断会议请求信息， 具体为： 信息， 该中断会议请求信息中携带有需要中断会议的会议标识信息；
请求信息，该中断会议请求信息中携带有需要中断的一个或多个入会终端的标 识符； 请求信息， 该中断会议请求信息中，携带有需要中断会议的一个或多个入会终 端的标识符及会议标识信息。
优选的是， 所述 MCU还可以预先设定中断时间 （如午餐时间） ， 在预先 设定的中断时间到达时向所有或者部分入会终端发送中断会议指示信息。
2、 所述入会终端在接收到所述中断会议指示信息后， 关闭其媒体通道， 并保存通道参数， 进入待机或者休眠状态。
在本实施例中， 入会终端与 MCU之间可以包含多个媒体通道， 每个媒体 通道都可以用于发送或者接收媒体码流，入会终端在接收到 MCU发送的中断 会议指示信息后， 将关闭该入会终端的媒体通道， 并保存通道参数。 其中， 所 述通道参数包括音视频的格式、音视频可供选择的编码类型、音视频速率以及 通信速率等。 如图 4所示入会终端 T1和主 MCU存在一条通道， 通过该通道 发送或者接收媒体码流， 当 T1接收到 MCU发送的中断会议指示信息后， T1 将关闭该通道。
作为本发明的一个实施例， 当具有中断权限的入会终端向 MCU发送中断 请求信息后， MCU向所述具有中断权限的入会终端发送响应信息， 然后再向 其他入会终端发送中断会议指示信息。所述具有中断权限的入会终端在接收到 所述响应信息后，关闭其媒体通道，并保存通道参数，进入待机或者休眠状态。 而其他入会终端在接收到所述中断会议指示信息后， 关闭其媒体通道， 并保存 通道参数， 进入待机或者休眠状态。
在本实施例中， 为了避免入会设备运行的功耗， 所有入会终端在关闭媒体 发送或接收通道、保存通道参数后，将进入待机或者休眠状态。需要说明的是， 当入会终端较复杂， 如存在多个 CPU时， 可以仅运行主 CPU, 其他 DSP和外 部设备全部休眠。 当然也可以将主 CPU也强制休眠。
优选的是， 为了保证在断电等情况下中断后的会议仍能顺利的重新召开， 本实施例的入会终端在接收到中断会议指示信息后， 还将保存当前的会议参 数。 其中， 所述会议参数包括该入会终端当前的观看画面 （如入会终端 T1输 出入会终端 T3和 T4的画面， 或者入会终端 T1选看入会终端 T2的画面） 、 是否具有中断权限等。
作为本发明的另一实施例， 所述方法还包括：
在所述 MCU向所有入会终端发送中断会议指示信息后， 关闭 MCU的媒 体通道， 并保存通道参数、 当前会议数据及各入会终端的状态。
在本实施例中， 所述会议数据包括所有入会终端的会议参数； 所述通道参 数包括 MCU与所有入会终端连接通道的参数； 各入会终端的状态包括各入会 终端广播、 观看、 点名以及发言等状态。 需要说明的是， MCU在向所有入会 终端发送中断会议指示信息后， 将保存当前会议数据， 则本实施例中各入会终 端保存的会议参数相当于是该会议数据的备份。 当然也可以将 MCU保存的当 前会议数据作为各入会终端会议参数的备份，目的都是保证会议中断后能顺利 的重新召开。
3、 多点控制单元 MCU向所述入会终端发送恢复会议指示信息。
在本实施例中， MCU根据如表一所示的扩展的会议控制信息， 向各入会 终端发送恢复会议指示信息来实现会议中断后的恢复。 需要说明的是， 如果
MCU的媒体通道关闭了， MCU在向所述入会终端发送恢复会议指示信息前， 需要先打开 MCU的媒体通道。 复请求信息， MCU在接收到具有中断权限的入会终端发送的恢复会议请求信 息后， 打开 MCU的媒体通道（在 MCU的媒体通道关闭的情况下 ) , 向所有 或者部分入会终端发送恢复会议指示信息（如图 4所示）。 需要说明的是， 所
议请求信息， 具体为： 信息， 该恢复会议请求信息中携带有需要恢复会议的会议标识信息； 请求信息，该恢复会议请求信息中携带有需要恢复会议的一个或多个入会终端 的标识符； 请求信息， 该恢复会议请求信息中，携带有需要恢复会议的一个或多个入会终 端的标识符及会议标识信息。
优选的是， 所述 MCU还可以预先设定恢复时间或者在中断会议时就设定 好恢复时间， 在预设的恢复时间到达时打开 MCU的媒体通道， 向所有或者部 分入会终端发送恢复会议指示信息。
需要说明的是， 除具有中断权限的入会终端或者 MCU外， 其他入会终 端都无权恢复会议。
4、 所述入会终端在接收到所述恢复会议指示信息后， 根据预存的通道参 数打开其媒体通道。
在本实施例中，由于各入会终端在会议中断时，保存了其对应的通道参数， 所以各入会终端在接收到所述恢复会议指示信息后，将根据存储的通道参数打 开对应的媒体通道， 以继续接收或者发送媒体码流， 恢复中断后的会议。
本实施例在会议中断后， 可以通过具有中断权限的入会终端或者 MCU发 送会议控制信令的方式快速的恢复会议， 操作简单， 具有较强的实用性。
在本实施例中， 当所述 MCU同时控制多个会议， 其中只有一个会议需要 中断或恢复时， MCU可以根据预先存储的会议信息，对其中一个会议进行中 断或恢复， 或者识别出与所述具有权限的请求终端相关的所有入会终端， 只向 这些终端发送中断或恢复指示，或者向所有终端发送中断或恢复指示时携带这 些终端的标识， 以便于对选定的入会终端进行中断或恢复控制。 其中， 所述会 议信息包含会议标识和与该会议相关的入会终端的信息。
例如： 如图 4, 具有中断权限的入会终端 T2向 MCU发送中断会议请求 信息， 所述中断会议请求信息中携带有需要中断入会终端的唯一标识符 Tl、 Τ2, 即对入会终端 T1和 Τ2进行会议中断， MCU在接收到该携带有唯一标识 符的中断会议请求信息后， 向入会终端 T1和 Τ2发送中断会议指示信息， 入 会终端 T1和 Τ2在接收到所述中断会议指示信息， 关闭其媒体通道， 保存通 道参数， 进入待机或者休眠状态。 具有中断权限的入会终端 Τ2向 MCU发送 恢复会议请求信息，所述恢复会议请求信息中携带有需要恢复入会终端的唯一 标识符 Tl、 Τ2, 即对入会终端 T1和 Τ2进行会议恢复， MCU在接收到该携 带有唯一标识符的恢复会议请求信息后， 向入会终端 T1和 Τ2发送恢复会议
指示信息，入会终端 T1和 T2在接收到所述 MCU发送的所述恢复会议指示信 息时， 根据所保存的通道参数打开其媒体通道， 恢复工作状态。
