实施例 3
本实施例具体描述一种会议切换的方法, 该方法涉及会议终端侧和控制 侧, 主要用于描述会议终端侧欲加入目的会议, 并主动发送切换流程的场景。 在本实施例中该会议终端侧具体以会议终端 T1 , 该控制侧在本实施例以及下 述各实施例中具体以 MCU1作为多点控制服务器为例进行叙述, 为了便于描 述, 将 T1 当前所在的会议称为原会议, 设该原会议为会议 1 , 将 T1请求切 换的会议称为目的会议, 设其为会议 2。
需要说明的是:本实施例的方法适合同一 MCU上的不同会议间的切换场 景,即在本实施例提供的方法的执行流程是以该会议 1和会议 2均属于 MCU1 为前提条件进行描述的。 如图 4所示, 该方法包括如下步骤:
T1在会议 1中时, 与会者出于需要, 希望参加会议 2 , 此时:
步骤 301 , T1发送请求切换到会议 2的切换请求消息到 MCU1 , 所述切 换请求消息中至少包含有会议 2的标识、 切换请求类型信息和切换验证信息。
优选的,切换验证消息,用于验证请求 T1的权限, 以便保证用户安全性; 优选的, 切换请求类型信息, 用于指示 T1欲切换的类型, 具体有两种切 换类型, 分别是切换后脱离原会议的连接, 和切换后保持与原会议的连接, 釆用不同的方式的大致处理过程是当切换类型时切换后脱离原会议的连接 时, 需要将 T1的信息更新到目的会议中, 当切换类型时切换后保持与原会议 的连接时, 需要或者原会议是否与目的会议保持有联系, 若有则可利用原有 的目的会议的资源执行会议切换, 若没有则需要为目的会议配置新的资源后, 在利用该新的资源执行会议切换。
步骤 302, MCU1接收到该请求切换到会议 2的切换请求消息, 并根据所 述切换验证信息验证所述 T1是否有切换到会议 2的权限,如果验证结果表示 T1有切换到会议 2的权限, 则执行步骤 303; 如果校验结果表示 T1无权限切 换到会议 2, 执行步骤 304。
其中, 上述切换验证信息和验证所述会议终端是否有切换到会议 2 的权 限的过程可按照现有方式执行。 例如: 所述切换验证信息可包括: 所述 T1的 标识, MCU1可根据所述会议终端的标识和所述会议 2的标识验证所述 T1 是否有权限切换到所述会议 2。
步骤 303 , MCU1发送同意切换的切换响应消息到 Tl , T1接收到该切换 响应消息, 并执行步骤 305。
步骤 304, MCU1发送拒绝切换的切换响应消息到 Tl , T1接收到该切换 响应消息, 保持当前会议 1 的状态不变, 切换流程至此将结束, 无需再执行 下述步骤。
步骤 305 , MCU1按照所述切换请求类型信息进行切换到会议 2的处理。 若 MCU1切换成功, MCU1发送切换成功的切换指示消息到 T1 , 并执行步骤 306; 若 MCU1切换失败, 则发送切换失败的切换指示消息到 T1 , 转向执行 步骤 307。
该步骤 305 中当所述切换请求类型信息可以为切换后脱离原会议(即会 议 2 ) 的连接, 或者切换后保持与会议 2的连接。
其中, 当该切换请求类型信息表示: 切换后脱离会议 1 的连接时, 说明 可保持并利用原有的媒体通道进行会议 2 的交互。 因此, 上述按照所述切换 请求类型信息进行切换到会议 2的处理至少包括如下项目:
MCU1在会议 2中为 T1申请新的会场标识, 该会场标识可以是 MT号, 或者其他的 ID标识;
MCU1在所述会议 2中增加 T1的信息, 包括: T1所支持的媒体协议, 音频以及视频格式, 端口信息等;
MCU1将原会议的媒体流更新为该会议 2的媒体流, 并在更新成功后更 新会议 1 的会议信息, 例如: 刷新会场的状态, 不在会议 1 中。 其中, 媒体 流指音频流, 视频流以及一些控制信令等组成的码流。
其中, 若如上项目的处理均成功, 则按照 MCU1 切换成功处理, MCU1 发送切换成功的切换指示消息到 T1 , 并且该新申请的会场标识可用于加入到 将要发送的切换指示消息中以便通知 T1 , 并执行步骤 306; 若如上项目中任 意一项处理失败, 则按照 MCU1切换失败处理, 将发送拒绝切换的切换响应 消息到 T1 , 转向执行步骤 307。
当所述切换请求类型信息表示: 切换后保持与会议 1 的连接时, 说明需 要建立新的媒体通道以便进行与会议 2 的交互。 因此, 上述按照所述切换请 求类型信息进行更新到会议 2的处理包括:
MCU1在 T1所对应的活动会议记录中查找会议 2,
若查找到该会议 2, 则说明 T1与会议 2仍然保持联系, 即已经存在用于 传输会议 2媒体流的媒体通道了, 那么此时可无需为会议 2建立新的媒体通 道, MCU1可根据查找到的所述目的会议的资源 (该资源指媒体通道, 会议 标识等)执行切换到所述目的会议的过程, 具体地, MCU1 需要至少进行如 下过程:
MCU1查找 T1在所述会议 2中的会场标识;
MCU1将发送到 T1媒体流更新到该会议 2的媒体流, 并在更新成功后, 更新会议 1 的会议信息; 例如: 刷新会场的状态, 不在会议 1 中, 但可保持 与会议 1的联络。
其中, 若如上项目的处理均成功, 则按照 MCU1 切换成功处理, MCU1 发送切换成功的切换指示消息到 T1 , 并且该查找到的会场标识可加入到将要 发送的切换指示消息中以便通知 T1 , 并执行步骤 306; 若如上项目中任意一 项处理失败, 则按照 MCU1切换失败处理, 将送拒绝切换的切换响应消息到 T1 , 转向执行步骤 307。
若未查找到该会议 2 , 需要为所述目的会议配置资源, 并根据所述配置的 资源执行切换到所述目的会议的过程。 因为若为查找到该会议 2, 说明 T1没 有取得与会议 2的联系, 因此需要建立用于会议 2的新的媒体通道(包括: 视频通道、音频通道已经其它媒体通道等), 以便传送会议 2的媒体流, 此时, 具体地, MCU1需要至少进行如下过程: 在会议 2中为 Tl申请新的会场标识; 该会场标识可以是 MT号, 或者其 他的 ID标识;
在该会议 2中增加 T1的信息; 包括: T1所支持的媒体协议, 音频以及 视频格式, 端口信息等;
为会议 2建立媒体通道, 并用所述建立的媒体通道的传送到该会议 2的 媒体流, 在成功完成后, 更新会议 2 的会议信息, 例如: 刷新会场的状态, 不在会议 1中, 但可保持与会议 1的联络。
同理, 若如上过程的处理均成功, 则按照 MCU1 切换成功处理, MCU1 发送切换成功的切换指示消息到 T1 , 并且该新申请的会场标识可加入到将要 发送的切换指示消息中以便通知 T1 , 并执行步骤 306; 若如上过程中任意一 项处理失败, 则按照 MCU1切换失败处理, 将发送拒绝切换的切换响应消息 到 T1 , 转向执行步骤 307。
在这种切换后保持与会议 1 的连接的切换请求类型信息中, 当切换成功 后, T1就使用新媒体通道作为主通道传送媒体,本地声音和图像使用新媒体 通道传送到会议 2中, 同时会议 2的声音和图像也通过新通道传送到 Tl , T1 当前的主画面看到的是会议 2 的图像; 另外, 原有媒体通道用于接收会议 1 的声音和图像, T1可以使用辅助画面来观看会议 1图像, 并切换不同会议的 声音到音响输出。 同时会议终端 T1仍可以发送特殊图像信息告知会议 1仍然 保持联系(以免在会议 1中看到的 T1是离线状态 ), 但会议终端 T1本地的声 音和图像只会发送给当前所在会议, 不会送给会议 1。 当会议 1需要会议终端 T1参与, 会议终端 T1随时切换进入会议 1 , 切换完成后, 主画面的图像和声 音来源与会议 1。
步骤 306, T1接收到来自 MCU1的切换成功的切换指示消息, 并根据所 述切换指示消息配合 MCU1切换到会议 2, 并可结束本次会议切换流程。
其中, 具体切换到会议 2 的过程包括: 更新会议信息, 例如: 指示出当 前会议为会议 2, T1在该会议 2中的会场标识等,并向 MCU1发送参考帧(如 I帧)刷新请求, MCU1在收到该参考帧的刷新请求后, 向 T1发送参考帧图 像, T 1的远端画面切换到会议 2中的画面, 进入到会议 2 , 进行媒体通话。 会议切换前后, T1和 MCU1上的媒体收发信道保持不变, 变化的是 T1 收到的媒体流, 它不是来自会议 1 , 而是会议 2。 整个切换过程画面不会出现 中断。
其中, 需要说的是: 若 T1发送的切换请求消息中包含的切换请求类型信 息为: 切换后脱离原会议的连接时, T1通过发送参考帧刷新请求切换到会议 2的过程具体指: 离开当前会议, 并通过当前会议的媒体通道收发会议 2的媒 体流; 若 T1发送的切换请消息中包含的切换请求类型信息为所述切换后保持 与原会议的连接时, 通过发送参考帧刷新请求切换到会议 2 的过程具体指: 保持当前会议, 并通过 MCU1所建立的新媒体通道传送会议 2的媒体流。
步骤 307 , T1接收到 MCU1的切换失败的切换指示消息,代表所述 MCU1 没能按照所述切换请求类型信息切换到会议 2, 或者 T1未能通过权限验证, 因此, 根据所述切换指示消息配合 MCU1切换到所述目的会议具体为: 保持 会议 1的状态, 即仍然在会议 1中, 仍然处于会议 1的媒体通道和画面不变, 包括保持信令及媒体状态不变, 结束本次会议切换流程。
在本实施例中, 上述流程中涉及的切换消息 (包括: 切换请求消息、 切 换响应消息以及切换指示消息)具体可通过如下消息实现。

例如: 当用户在电视图像界面选择会议时, 用户在该界面上的操作都会 将通过 FECC消息通知到 MCU。 MCU通过 FECC消息接收到用户的操作后, 执行相应处理。 若为切换请求, 则进行切换; 若切换成功, 则进入目的会议 的画面; 若切换失败, 则保持原会议状态不变。
在本实施例提供的方法中, 可通过切换请求消息启动会议切换流程, 操 作较简单, 无需切断原会议的连接通道, 不必中断原会议的远端图像, 减少 了会议切换过程中必须重新呼叫如何的过程, 提高了切换速度, 可实现会议 平滑切换, 即可使原会议的远端图像在不中断的情况下切入到目的会议的远 端图像, 为用户在整个会议切换过程中带来了良好体验。
实施例 4
本实施例提供一种会议切换的方法, 该方法涉及会议终端侧和控制侧, 在本实施例中该会议终端侧具体以会议终端 T1 , 该控制侧具体以 MCU1 和 MCU2为例, 为了便于描述, 将 T1当前所在的会议称为原会议, 设该原会议 为会议 1 , 将 T1请求切换的会议称为目的会议, 设其为会议 2。 其中, 设会 议 1属于 MCU1 , 会议 2属于 MCU2。
相对于实施例 3来说, 需要说明的是: 本实施例的方法适合的不同 MCU 上的不同会议间的切换场景, 即在本实施例提供的方法的执行流程是以该会 议 1属于 MCU1 , 会议 2属于 MCU1为前提条件进行描述的。
如图 5所示, 该方法包括:
终端 T1在会议 1中时, 与会者出于参会需要, 希望终端 T1参加会议 2, 此时:
步骤 401 , T1发送请求切换到会议 2的切换请求消息到 MCU1 , 所述切 换请求消息中包含有代表会议 2 的标识; 优先地, 在本实施例中, 所述切换 请求消息中还包括切换请求类型信息和切换验证信息。
步骤 402 , MCU1 接收到该请求切换到会议 2 的切换请求消息, MCU1 根据所述会议 2的标识获知该会议 2是 MCU2的下属会议,则以 T1的名义向 MCU2发起对会议 2的呼叫。若 MCU1呼叫不成功,则执行步骤 408;若 MCU1 呼叫成功, 则执行步骤 403。
其中, 因为现有技术中, 每个 MCU都可知其下属有哪些会议的信息, 以 及其它的各个 MCU的下属均有哪些会议的信息, 因此对于任意一个 MCU来 说, 可根据这些信息判断某一会议是否为其下属的会议, 即本地会议, 还是 其它 MCU的下属会议, 即异地会议, 在本实施例中 MCU1 同样可轻易获知 该会议 2是 MCU2的下属会议, 具体获知方法与现有技术相同, 对此, 本实 施例不再赘述。
另外, 向 MCU2发起对会议 2的呼叫的具体执行过程可按照现有技术中 正常进入会离会进行, 在此不赘述。
步骤 403 , MCU1将 T1请求切换到会议 2的切换请求消息转发到 MCU2。 MCU2根据该切换请求消息中包含的所述切换验证信息,验证所述 T1是否有 切换到会议 2的权限, 如果验证结果代表 T1有切换到会议 2的权限, 则执行 步骤 404; 如果校验结果代表 Tl无权限切换到会议 2 , 执行步骤 405。
步骤 404 , MCU2发送同意切换的切换响应消息到 MCU1 , 同时在该切换 响应消息中 MCU1在 MCU1与 T1之间建立新的通道, 以便传送会议 2媒体 流。 MCU1接收到该切换响应消息后, 将该切换响应消息转发到 T1 , 并相应 的建立用于传送会议 2媒体流的上述通道, 执行步骤 406。
需要说明的是: 上述步骤 404中在 MCU1与 T1之间建立新的通道是在 T1需要与 MCU1保持会议 1的情况下执行的步骤, 若 T1不需要保持与会议 2的联系, 则可无需建立新的通道, 在退出会议 1后, 保持已经建立的传送会 议 1的媒体流的通道, 并利用该通道传送会议 2的媒体流。
步骤 405 , MCU2发送拒绝切换的切换响应消息到 Tl , MCU1将该切换 响应消息转发到 Tl , T1可保持会议 1的状态不变, 因为 T1没有通过 MCU2 的验证, 所以本流程至此结束, 无需再进行下述步骤。
步骤 406 , MCU2在 MCU1与 MCU2之间建立新的用于传送会议 2的媒 体流的通道, 在通道建立后, 按照所述切换请求类型信息进行切换到会议 2 的处理。 若 MCU2切换成功, MCU2将分配给 T1的在会议 2中的会场标识 发送到 MCU1 , MCU1在收到该 T1的会场标识后(该会场标识可以是 MT号, 或者其他唯一性的 ID ), 发送切换成功的切换指示消息到 Tl , 更新会议 1 的 信息, 关联 T1与 MCU1 , 以及 MCU1与 MCU2建立的两段通道, 使会议 2 的媒体流可以通过该两段通道传送到 T1 , 并执行步骤 407; 若 MCU2切换失 败, 则发送切换失败的切换指示消息到 MCU1 , MCU1 将该失败的切换指示 消息转发到 T1 , 转向执行步骤 408。
该步骤 406中 MCU2按照所述切换请求类型信息进行切换到会议 2的处 理的具体执行过程可参照实施例 3中的步骤 305的 MCU1的操作。
步骤 407 , T1接收到来自 MCU1的切换成功的切换指示消息, 并切换到 会议 2, 并可结束本次会议切换流程。
步骤 407的具体操作可参考实施例 3中的步骤 306,其中,不同之处在于: 该 MCU1将转发 T1发送的 I帧请求到 MCU2, MCU2转发媒体流。即: MUC1 将充当 Tl与 MCU2之间的双向中继, 转发 T1与 MCU2之间进行的交互。 由 此, 可实现 T1加入 MCU2上会议 2的视频会议。
步骤 408, T1接收到 MCU1的切换失败的切换指示消息, 并保持会议 1 的状态, 即仍然在会议 1 中, 仍然为会议 1 的媒体通道和画面不变。 结束本 次会议切换流程。
在本实施例中涉及的切换消息具体实现可参照上述实施例 3 中对应的切 换消息实施方式, 在此不赘述。 不必中断原会议的远端图像, 减少会议切换过程中必须重新呼叫如何的过程 , 提高切换速度, 可实现会议平滑切换的技术效果, 为用户在整个会议切换过 程中带来了良好体验。
实施例 5

在该方法中, 设在会议终端侧被邀请加入第二会议的会议终端为 T1 , 在 控制侧控制该过程的是 MCU1 , 为了便于描述, 将 T1当前正在参加的会议称 为第一会议,设该第一会议为会议 1 ,将 T1被邀请加入的会议称为第二会议, 设其为会议 2。 其中, 设会议 1和会议 2均属于 MCU1。
如图 6所示, 该方法包括:
步骤 501 , MCU1接收到某一会议终端邀请 T1加入会议 2的请求, MCU1 判断 T1是否已经正在参加第一会议, 若判定 T1未进入任何会议, 则可按照 现有技术的方式通过正常的呼叫方式呼叫 T1加入会议 2 , 在此不赘述; 若判 定该 T1正在参加会议 1 , 则发送切换请求消息到 T1 , 请求 T1切换到会议 2。
步骤 502, T1接收到来自 MCU1的上述切换请求消息后,如果拒绝加入, 则发送拒绝切换的切换响应消息到 MCU1 , T1保持原有状态,处于会议 1中, MCU1在接收到 T1发出的拒绝切换的切换响应消息后, 响应邀请 T1失败的 消息到发出该请求的会议终端, 本流程至此结束, 并不再执行下述步骤; 如 果同意加入会议 2, 则发送同意切换请求的切换响应消息到 MCU1。
步骤 503 , MCU1接收到来自 T1的同意切换的切换响应消息后, 至少进 行 ¾口下项目:
MCU1为 T1分配在会议 2中的会场标识, 该会场标识可以是 MT号, 或 其他唯一性的 ID;
更新会议 2的会议信息;
如果上述两项均处理成功, 则将指示已加入会议的切换指示消息发送到 T1 , 该切换指示消息中可以包含有该分配的会场标识和会议 2的会议信息; 如果有任意一项处理失败, 则发送切换失败的切换指示消息到 T1 , 本流程到 此结束。
步骤 504, T1接收到该 MCU1的切换指示消息, 如果该切换指示消息指 示已加入会议 2 , 则切换到会议 2。
具体切换到会议 2的执行过程可参考上述实施例 3中的步骤 306;如果该 切换指示消息指示切换失败, 则保持会议 1的状态不变。
另外, 在本实施例中涉及的切换消息具体实现可参照上述实施例 3 中对 应的切换消息实施方式, 在此不赘述。
本实施例提供的方法可取得使某个正在参加第一会议的会议终端在接收 到某一邀请加入第二会议的请求后, 平滑地切换到第二会议的技术效果; 在 整个切换过程中无需切断第一会议的连接通道, 提高了切换速度, 提高了在 接受邀请后加入第二会议过程中的用户体验。
