Description

多媒体会议管理方法及设备 技术领域
本发明涉及通信技术领域， 特别涉及一种多媒体会议管理方法及设备。 背景技术
多媒体会议是指一种三方以上的多媒体通信业务。 多媒体会议允许用 户进行创建、 管理、 结束、 加入或离开会议， 同时也允许会议系统向各与 会者发送各种动态会议信息。
目前， 现有的多媒体会议实现方法请参阅图 1 , 以五方会议为例， 包括 以下步驟：
步驟 1〜步驟 9、 主用户端 （CALLID1 )通过应用端 （ APP )发送建立 会议组请求， 会议管理端接收并解析该请求， 建立会议组， 并为其分配会 议资源， 使主用户端 （CALLID1 )加入该会议组；
步驟 10〜步驟 18、 用户端 （CALLID2 )通过应用端 （APP )发送加入 该会议组请求， 会议管理端接收并解析该请求， 并为其分配该会议组的会 议资源， 使用户端 （ CALLID2 )加入该会议组；
步驟 19〜步驟 27、 用户端 （CALLID3 )通过应用端 （APP )发送加入 该会议组请求， 会议管理端接收并解析该请求， 并为其分配该会议组的会 议资源， 使用户端 （CALLID3 )加入该会议组；
步驟 28〜步驟 36、 用户端 （CALLID4 )通过应用端 （APP )发送加入 该会议组请求， 会议管理端接收并解析该请求， 并为其分配该会议组的会 议资源， 使用户端 （ CALLID4 )加入该会议组；
步驟 37〜步驟 45、 用户端 （CALLID5 )通过应用端 （APP )发送加入 该会议组请求， 会议管理端接收并解析该请求， 并为其分配该会议组的会 议资源， 使用户端 （CALLID5 )加入该会议组；
通过上述方法，使主用户端及其他 4个用户端组成会议组，请参阅图 2, 主用户端及其他 4个用户端打开该会议组的会议资源， 并通过 ConfRes模 块（媒体流处理模块）对该会议组的成员的媒体流进行混音， 然后分别发 送至各用户端， 使每个用户均能接收到其他用户的媒体流， 从而达到相互 通信的目的。 然而， 每个会议组所能承载的与会成员的数量是有限制的， 当与会成员的人数大于会议组所能承载的与会成员的最大数量时， 就需要 建立新的会议组， 以满足与会成员数量的要求， 但目前未解决多个会议组 的与会成员之间进行通信的问题， 使得在进行多媒体会议时与会成员的人 数受到会议组最大承载数量的限制。
综上所述， 目前会议组之间无法进行通信， 使得进行多媒体会议时与 会成员的人数受到限制。 发明内容
本发明实施例提供了一种多媒体会议管理方法及设备， 用于解决现有 技术中存在的会议组之间无法进行通信， 使得进行多媒体会议时与会成员 的人数受到限制的问题。

在所述已创建的会议组中没有未分配的会议资源时， 创建一个从会议 组， 为所述从会议组分配会议资源及至少一个级联资源， 并为所述与会成 员端分配所述从会议组的一个未分配的会议资源；
将所述从会议组的一个未与其它会议组的级联资源连接的空闲级联资 源与任一已创建的会议组的一个空闲级联资源连接。
优选的， 所述判断是否有未分配的会议资源的会议组之后还包括： 在所述已创建的会议组中有未分配的会议资源时， 为所述与会成员端 分配一个所述未分配的会议资源。
优选的， 会议组之间采用直线或网状方式相连接。
本发明实施例还提供了一种多媒体会议管理设备， 包括： 个级联资源； 并将不同会议组的级联资源连接， 其中一个会议组的一个级 联资源只与另一个会议组的一个级联资源连接， 任意一个会议组都能通过 级联资源直接或间接与其它会议组连接；；
媒体流处理模块， 设置为将需要在会议组之间传输， 且经过混音处理 后的媒体流通过连接后的级联资源传输。
优选的， 所述的资源管理模块具体设置为： 在接收到来自主成员端的 创建会议请求指令后， 创建所述主会议组， 为所述主会议组分配会议资源 及至少一个级联资源， 并为所述主成员端分配所述主会议组的一个未分配 的会议资源。
优选的， 所述的资源管理模块具体设置为：

背景技术中未解决多个会议组的与会成员之间进行通信的问题， 使得 在进行多媒体会议时与会成员的人数受到会议组最大承载数量的限制。 由 于本发明实施例中分配给每个会议组至少一个级联资源， 且各会议组的级 联资源相互连接， 能够将级联资源所在会议组的媒体流传送至其他会议组 的级联资源处， 使得多个会议组的与会成员之间能够进行相互通信， 这样， 在进行多媒体会议时， 与会成员的人数不再受到会议组最大承载数量的限 制。
其中， 本发明实施例中的多媒体包括： 音频、 或视频、 或消息、 或各 种数据与应用， 或上述任意对象的组合等。 本发明实施例可以基于 H.323 标准协议， 或给予 SIP ( Session Initial Protocol, SIP )协议， 或者其他类型 的协议。
本发明实施例中的混音处理为实时处理， 当任一与会成员发言时， 即 进行混音处理， 并把混音处理后的媒体流通过级联资源传送至其他与会成 员端， 详细描述见下述对不同会议组之间的混音处理过程。
下面结合说明书附图对本发明实施例作进一步详细描述； 需要说明的 是， 附图中均以每个会议组的最大承载数量是 5 为例， 但不以此为限， 该 数量只是说明性的， 并非限制性的。 请参阅图 3 ,为本发明第一实施例提供的一种多媒体会议管理方法流程 图， 该方法包括以下步驟： 步驟 102、将不同会议组的级联资源连接， 其中一个会议组的一个级联 资源只与另一个会议组的一个级联资源连接， 任意一个会议组都能通过级 联资源直接或间接与其它会议组连接；
步驟 103、将需要在会议组之间传输， 且经过混音处理后的媒体流通过 连接后的级联资源传输。
需要说明的是， 步驟 102 中的一个会议组的一个级联资源只与另一个 会议组的一个级联资源连接是指， 一个会议组的一个级联资源不能分别与 其他会议组的多个空闲的级联资源连接。 比如， 图 5A中， 与会议组 2连接 的会议组 1的级联资源， 其不能再与会议组 3和 /或会议组 4的空闲级联资 源连接； 若该会议组 1 的级联资源与会议组 2断开连接， 则其可以重新选 择与会议组 2或会议组 3或会议组 4的一个空闲级联资源连接。
优选的， 步驟 103中， 两个会议组的通信过程为：
若其中一个会议组中的任一成员发言， 立即对该会议组与会成员的媒 体流及第一级联资源的媒体流进行混音处理， 并将混音处理后的媒体流作 为第一级联资源的媒体流； 然后将该会议组的级联资源的媒体流传送至另 一会议组的每一个与会成员端， 并同时通过该会议组的级联资源将该混音 处理后的媒体流传送至另一会议组的级联资源处， 通过另一会议组的级联 资源将该混音处理后的媒体流传送至另一会议组的每一个与会成员端。
进一步， 在本实施例中， 至少两个会议组中包括一个主会议组和至少 一个从会议组；
具体地说， 为主会议组分配至少一个级联资源包括以下步驟： 在接收到来自主成员端的创建会议请求指令后， 创建所述主会议组， 为所述主会议组分配会议资源及至少一个级联资源， 并为所述主成员端分 配所述主会议组的一个未分配的会议资源。
优选的， 所述为主会议组分配至少一个级联资源之后还包括： 在接收到来自与会成员端的加入会议请求指令后， 判断已创建的会议 组中是否有未分配的会议资源；
在所述已创建的会议组中没有未分配的会议资源时， 创建一个从会议 组， 为所述从会议组分配会议资源及至少一个级联资源， 并为所述与会成 员端分配所述从会议组的一个未分配的会议资源；
将所述从会议组的一个未与其它会议组的级联资源连接的空闲级联资 源与任一已创建的会议组的一个空闲级联资源连接。
本发明实施例中的会议组的空闲级联资源是指， 未与其它会议组的级 联资源连接的级联资源。
优选的， 所述判断是否有未分配的会议资源的会议组之后还包括： 在所述已创建的会议组中有未分配的会议资源时， 为所述与会成员端 分配一个所述未分配的会议资源。
上述实施例中， 在接收到 Info ( create&join )时,创建主会议组并在分配 会议资源时多分配一个级联资源， 该级联资源是当会议成员数大于该主会 议组所能支持的最大成员数时与新的会议组进行级联；
在接收到 info ( join ) 时， 分配该主会议组的会议资源， 加入该会议； 当主会议组的会议成员数超过了其所能支持的最大成员数时， 此时有 新的与会成员端加入会议时就会创建一个从会议组， 除了分配该与会成员 端用来加入会议的会议资源， 还会分配两个级联资源， 该两个级联资源用 来与其他会议组的级联资源进行连接， 这样后面新的与会成员端加入会议 时， 就可加入到从会议组中； 此时， 将属于从会议组的与会成员和从会议 组的级联资源进行混音， 这样， 从会议组的级联资源的媒体流就是从会议 组里的与会成员端的媒体流， 会议组之间通过级联资源之间的 RTP
( Real-time Transport Protocol, 实时传送协议 )媒体流进行交互， 从而实现 两个会议组之间的成员相互交流。
本发明的实施例中相连接的两个会议组之间可以有一对连接的级联资 源， 也可有多对连接的级联资源。
在实施中， 将一个新创建的从会议组的级联资源与已创建的会议组的 空闲的级联资源连接方式有很多种， 下面列举几种进行简单描述：
需要说明的是， 为了说明本实施例， 使用了 "会议组 1"、 "会议组 2"、 "会议组 3"等字样， 对不同会议组进行区分， 但并不对会议组操作优先级 进行限制， 会议组 1表示任一会议组， 会议组 2表示与会议组 1不同的任 一会议组， 会议组 3表示与会议组 1及会议组 2不同的任一会议组。
(一 )假设图 4A及图 4B中，会议组 1与会议组 2为已创建的会议组， 其中会议组 1为主会议组， 会议组 2为从会议组：
( 1 )如图 4A所示： 会议组 1通过其一个级联资源与会议组 2的级联 资源连接； 会议组 3为新增加的会议组， 其通过级联资源与会议组 1 的空 闲的级联资源连接。 此连接方式中， 会议组 1与会议组 2之间通过会议组 1 的级联资源与会议组 2 的级联资源连接， 该连接为直接连接方式， 同理会 议组 1及会议组 3之间也是直接连接； 而会议组 1与会议组 3的级联资源 是通过会议组 1的两个级联资源实现的连接， 所以会议组 2及会议组 3之 间为间接连接。
( 2 )如图 4B所示： 会议组 1通过其级联资源与会议组 2的一个空闲 级联资源连接； 会议组 3为新增加的从会议组，通过其级联资源与会议组 2 的另一个空闲的级联资源连接。 此连接方式中， 会议组 1与会议组 2、 会议 组 2与会议组 3为直接连接； 会议组 1与会议组 3为间接连接。
(二）假设图 5 A〜图 5B中， 会议组 1、 会议组 2及会议组 3为任意三 个已建立的会议组（其可以为主会议组， 也可为从会议组）。
( 1 )如图 5A所示： 会议组 1的一个级联资源与会议组 2的空闲的级 联资源连接， 会议组 2的另一个空闲的级联资源与会议组 3的空闲的级联 资源连接； 会议组 4是新增加的从会议组， 目前， 会议组 1、 会议组 2及会 议组 3均有一个空闲的级联资源， 所以可以选择将会议组 4空闲的级联资 源与会议组 1或会议组 2或会议组 3的空闲的级联资源连接，图 5A中所示 是与会议组 3空闲的级联资源连接。 此连接方式中， 会议组 1与会议组 2、 会议组 1与会议组 3、会议组 3与会议组 4为直接连接； 会议组 1与会议组 3、 会议组 1与会议组 4、 会议组 2与会议组 4为间接连接。
( 2 )如图 5B所示： 会议组 1的两个空闲的级联资源分别与会议组 2 及会议组 3的空闲的级联资源连接。 会议组 4是新增加的从会议组， 目前， 会议组 1及会议组 3均有一个空闲的级联资源， 所以可以选择将会议组 4 空闲的级联资源与会议组 1或会议组 3的空闲的级联资源连接， 图 5B中所 示是与会议组 1空闲的级联资源连接。此连接方式中，会议组 1与会议组 2、 会议组 1与会议组 3、会议组 1与会议组 4为直接连接； 会议组 1与会议组 3、 会议组 2与会议组 4、 会议组 3与会议组 4为间接连接。
(三）假设图 6A〜图 6C中， 会议组 1、 会议组 2、 会议组 3及会议组 4为任意四个已建立的会议组（其可以为主会议组， 也可为从会议组）。
( 1 )如图 6A所示： 会议组 1的一个级联资源与会议组 2空闲的级联 资源连接， 会议组 2的另一个空闲的级联资源与会议组 3空闲的级联资源 连接， 会议组 3另一个空闲的级联资源与会议组 4空闲的级联资源连接。 会议组 5是新增加的从会议组， 目前会议组 3和会议组 4都有一个空闲的 级联资源，所以可以选择将会议组 5空闲的级联资源与会议组 3或会议组 4 空闲的级联资源连接， 图 6A中所示是与会议组 4空闲的级联资源连接。
( 2 )如图 6B所示： 会议组 1的三个空闲的级联资源分别与会议组 2 的空闲的级联资源、 会议组 3的空闲的级联资源及会议组 4的空闲的级联 资源。 会议组 5是新增加的从会议组， 目前会议组 1、 会议组 2、 会议组 3 都有一个空闲的级联资源， 会议组 4有两个空闲的级联资源， 所以可以选 择将会议组 5空闲的级联资源与会议组 1或会议组 2或会议组 3或会议组 4 空闲的级联资源连接， 图 6B中所示是与会议组 1空闲的级联资源连接。
( 3 )如图 6C所示： 会议组 1的一个级联资源与会议组 2空闲的级联 资源连接， 会议组 2的另一个空闲的级联资源与会议组 3空闲的级联资源 连接， 会议组 3的另一个空闲的级联资源与会议组 4空闲的级联资源连接。 会议组 5是新增加的从会议组， 目前会议组 1、 会议组 3、 会议组 4都有一 个空闲的级联资源， 会议组 2有两个空闲的级联资源， 所以可以选择将会 议组 5空闲的级联资源与会议组 1或会议组 2或会议组 3或会议组 4空闲 的级联资源连接， 图 6C中所示是与会议组 2空闲的级联资源连接。
由于会议过程中随时会有与会成员端离开会议或新的与会成员端加入 会议； 创建了多个会议组后， 当每个新的与会成员端加入会议时， 首先判 断已创建的多个会议组是否已经满了， 如果不满， 则加入到不满的会议组 中， 如果满了， 就创建新的会议组， 并申请级联资源， 各个会议组之间的 媒体流交换就是通过级联资源来进行交互的， 这样多个与会成员端就可以 在一个会议中进行通话了。
下面以图 4A的连接方式为例，对多个会议组间的混音处理及通信过程 进行说明； 由于多个会议组间的混音处理及通信过程与三个会议组的相同， 多个会议组间的混音处理及通信过程可参阅下述说明， 此处不再赘述。
图 4A中， 若会议组 1有任一与会成员发言， 则对会议组 1的与会成员 的媒体流及其两个级联资源的媒体流进行混音处理， 将混音处理后的媒体 流作为每个级联资源的媒体流，并将该混音处理后的媒体流传送至会议组 1 的其他与会成员端； 同时分别通过两个级联资源将该混音处理后的媒体流 传送至会议组 1的级联资源处及会议组 3的级联资源处， 通过会议组 1的 级联资源将该混音处理后的媒体流发送至会议组 2 的每一个与会成员端； 同时通过会议组 3的级联资源将该混音处理后的媒体流传送至会议组 3的 每一个与会成员端。
若会议组 2有任一与会成员发言， 则对会议组 2的与会成员的媒体流 及其级联资源的媒体流进行混音处理， 将混音处理后的媒体流作为该级联 资源的媒体流， 并将该混音处理后的媒体流发送至会议组 2 的其他与会成 员端； 同时通过该级联资源将该混音处理后的媒体流传送至与会议组 2连 接的会议组 1的级联资源处， 通过会议组 1的级联资源将该混音处理后的 媒体流传送至会议组 1的每一个与会成员端及会议组 1的另一级联资源处； 同时通过会议组 1 的另一级联资源将将该混音处理后的媒体流传送至会议 组 3的级联资源处， 并通过会议组 3的级联资源将该混音处理后的媒体流 传送至会议组 3的每一个与会成员端。
若会议组 3有任一与会成员发言， 则对会议组 3的与会成员的媒体流 及其级联资源的媒体流进行混音处理， 将混音处理后的媒体流作为该级联 资源的媒体流， 并将该混音处理后的媒体流发送至会议组 3 的其他与会成 员端； 同时通过该级联资源将该混音处理后的媒体流传送至与会议组 3 连 接的会议组 1的级联资源处， 通过该会议组 1 的级联资源将该混音处理后 的媒体流传送至会议组 1 的每一个与会成员端及会议组 1的另一级联资源 处； 同时通过会议组 1 的另一级联资源将将该混音处理后的媒体流传送至 与会议组 1连接的会议组 2的级联资源处， 并通过会议组 2的级联资源将 该混音处理后的媒体流传送至会议组 2的每一个与会成员端。
图 4B中会议组 1、 会议组 2及会议组 3之间的通信过程与图 4A中的 通信过程相似， 此处不再赘述。
本发明实施例中多个会议组之间可采用直线形连接方式， 如图 7A所 示； 也可采用网状形连接方式， 如图 7B所示。
由于本发明实施例能够将级联资源所在会议组的媒体流传送至其他会 议组的级联资源处， 使得多个会议组的与会成员之间能够进行相互通信， 这样， 在进行多媒体会议时， 多个与会成员能够同时加入一个会议中， 使 与会成员的人数不再受到会议组最大承载数量的限制。
基于同一发明构思， 本发明实施例中还提供了一种多媒体会议管理设 备， 由于该设备解决问题的原理与上述多媒体会议管理方法相似， 因此该 设备的实施可以参见方法的实施， 重复之处不再赘述。
如图 8所示， 本发明实施例提供一种多媒体会议管理设备， 包括： 资源管理模块 10, 设置为为至少两个会议组中的每个会议组分配至少 一个级联资源； 并将不同会议组的级联资源连接， 其中一个会议组的一个 级联资源只与另一个会议组的一个级联资源连接， 任意一个会议组都能通 过级联资源直接或间接与其它会议组连接；；
媒体流处理模块 11 , 设置为将需要在会议组之间传输， 且经过混音处 理后的媒体流通过连接后的级联资源传输。
优选的， 所述的资源管理模块 10具体设置为： 在接收到来自主成员端 的创建会议请求指令后， 创建所述主会议组， 为所述主会议组分配会议资 源及至少一个级联资源， 并为所述主成员端分配所述主会议组的一个未分 配的会议资源。
优选的， 所述的资源管理模块 10具体设置为：
在接收到来自与会成员端的加入会议请求指令后， 判断已创建的会议 组中是否有未分配的会议资源； 在所述已创建的会议组中没有未分配的会 议资源时， 创建一个从会议组， 为所述从会议组分配会议资源及至少一个 级联资源， 并为所述与会成员端分配所述从会议组的一个未分配的会议资 源； 将所述从会议组的一个未与其它会议组的级联资源连接的空闲级联资 源与任一已创建的会议组的一个空闲级联资源连接。
优选的， 所述的资源管理模块 10具体设置为：
在所述已创建的会议组中有未分配的会议资源时， 为所述与会成员端 分配一个所述未分配的会议资源。
优选的， 会议组之间采用直线或网状方式相连接。
本发明实施例中的设备还可以包括：
指令解析模块（CALL ), 设置为接收并解析来自应用服务器的请求指 令， 并发送至资源管理模块 10及媒体流处理模块 11。
优选的， 本发明实施例中的设备可以是媒体服务器（Media Server, 简 称 MS )。
优选的， 在本发明实施例提供的设备与多个与会成员端之间设有一应 用服务器 (Application Server, 简称 App), 其接收多个与会用户端发送的请 求指令， 并将该请求指令传送至指令解析模块； 此处， 应用服务器是一个 独立的组件， 与控制层的软交换无关， 从而实现了业务与呼叫控制的分离， 有利于新业务的引入。
为保证会议管理设备的可靠性， 可以采用数据备份单元来存储与会成 员的相关数据， 该数据备份单元的实现形式有两种， 一是可以设置独立的 存储设备来实现各会议组的数据备份单元， 二是可以在公共数据区中开辟 专有的存储区域来实现各会议组的数据备份单元。 公共数据区中存储各会 议组与数据备份单元。 公共数据区中存储各会议组与数据备份单元的对应 关系。 该数据备份单元可以由一个独立的进程运行， 即不与其相应的会议 组共用同一个进程。
由于本发明实施例中分配给每个会议组至少一个级联资源， 并各会议 组的级联资源相互连接， 能够将级联资源所在会议组的媒体流传送至其他 会议组的级联资源处， 使得多个会议组的与会成员之间能够进行相互通信， 这样， 在进行多媒体会议时， 多个与会成员能够同时加入一个会议中， 使 与会成员的人数不再受到会议组最大承载数量的限制。
