Description

用于连接多个会议的方法和装置
技术领域
本发明涉及通信领域，更具体而言，涉及多会议连接方法和装置。
背景技术
MPTY(Multi Party，多方通话、会议)业务提供了一个用户(party，方)进行多方连接呼叫能力。也就是说三个用户或更多的用户同时进行双向通信。当被服务用户(Served Mobile Subscriber，是指调用MPTY操作的移动用户，他可以在激活MTPY呼叫状态下，对MPTY业务进行控制，即为主控方。)有一个激活呼叫和一个保持呼叫时，被服务用户可以调用MPTY，通过网络操作将激活呼叫和保持呼叫合并成MTPY呼叫，使服务用户与远端用户(Remote Party：是指MPTY呼叫中非被服务用户的其他方用户。)相互通信。并且在MPTY建立后，被服务用户可以保持当前的MPTY，与会议以外的用户进行通话，并在通话结束以后恢复呼叫会议；或者被服务用户保持当前的MPTY多方呼叫并发起一个新呼叫；或者被服务用户，在同时有一个MPTY呼叫和一个普通呼叫时，可以交替与两个呼叫中的用户通话或者将普通用户呼叫加入到MPTY多方呼叫中。
在目前，移动软交换架构由于其业务提供和呼叫控制分开、呼叫控制和承载连接分开、开放的接口便于第三方提供业务、智能化、个性化和移动性等特点而得到了广泛的应用。在移动软交换的架构下一个媒体网关控制器能够控制大量的媒体网关，这些媒体网关通常被分散放置到不同的位置用于覆盖一个较大范围的区域。
在这种组网方式下一方面建立跨多个媒体网关的会议需要占用大量的承载资源，随着会议用户数量的增加所占用的承载资源的数量也会较大的增加。另外，在目前有关MPTY协议(扩展H.248和3GPP协议)和实际应用中最大的用户数量为6方，随着业务的发展需要能够实现更多用户加入到会议中。并且能够将已经建立的多个会议连接起来，以实现更大范围内、更多用户之间的会议业务。
下面将参照图1和图2来详细说明根据相关技术的会议模型。
图1示出了一个根据相关技术的实现方法一的典型网关内的会议模型；图2示出了一个根据相关技术的实现方法二的典型网关内的会议模型。
在如图1所示的实现方法一中，参与会议的用户A、B、C连接到同一个媒体网关上，每个用户在媒体网关上分别对应端点为Ta、Tb、Tc。实现用户A、B、C之间的会议，只需要将三个端点集中到关联CTXa，由媒体网关混音实现会议功能。
在如图2所示的实现方法二中，参与会议的用户A、B、C连接到同一个媒体网关上，用户在媒体网关上分别对应端点为Ta、Tb、Tc，每个用户端点对应一个独立关联，分别为CTXa、CTXb、CTXc。为了实现用户A、B、C之间的会议功能，分别在每个用户关联中增加端点TA1、TB1、TC1，同时建立一个会议关联CTXmpty，在该关联中增加一一对应的端点TA0、TB0、TC0将关联之间连接起来。由会议关联CTXmpty混音实现会议功能。
在现有的移动通信系统中支持会议功能，会议(协议中规定参与会议的用户数最多为6方)是按照图一和图二中的两种组网模型实现的。
然而，目前的协议和相关的规范中只有针对同一个媒体网关内部的，单独一个会议的流程和组网。如果要实现将多个会议连接到一起可以采用将同一个网关中的几个会议中的用户合并到一起来实现(这样实现的结果还存在合并后的会议中最大用户数量不能超过6个的限制)。随着应用的发展，人们需要将多个会议进行连接，从而实现更大范围内的用户间通话。如：将已经存在的相关的几个会议连接起来，或者会议中用户发起建立新的会议，并将几个会议连接在一起，但是如何实现将多个会议进行连接，在现有的协议和相关的标准中都没有对其给出解决方案。
从以上的描述可以得知，现有的协议或规范中定义的实现方式，只能够完成同一个网关内的单个会议(最大6方)的建立过程，如果采用合并方式，则一方面对媒体网关有较高的要求，要求媒体网关能够支持一个会议的会话中支持超过6个端点的协议限制，同时在会议合并的过程中需要操作的端点数量多，导致操作效率不高，会议建立的过程较慢。并且在合并的方式中不能够实现分布在多个网关上的会议之间的合并。
因此，人们需要一种能够将多个会议连接的解决方案，能够解决上述相关技术中的问题。

具体实施方式
下面将参考附图详细说明本发明。
本发明提出在扩展H.248和3GPP协议的基础上，构建一种用于会议连接的新的网络连接模型和建立流程。从而实现将分布在同一网关或多个网关内的几个会议连接起来，实现更大范围内的会议业务。提供两种方案将多个会议进行连接。一种是会议中的远端用户发起建立新的会议，实现将多个会议连接起来；第二种是将两个已经建立的会议连接起来。
下面将参照图3和图4来详细说明根据本发明的方案1。
图3示出了根据本发明方案1的多会议连接方法；图4示出了根据本发明方案1的多会议连接装置400。
如图3所示，根据本发明方案1的多会议连接方法是通过会议中的远端用户发起建立新的会议，从而实现将多个会议连接起来，其包括以下步骤：
步骤S302，使用户离开其所参与的正在进行的会议，其中，该用户是正在进行的会议中的远端用户，其驻留在所述软交换网络中的用户设备(包括移动终端、电话机等)上，可选地，该用户通过呼叫保持操作离开正在进行的会议，其中，呼叫保持(Call Hold)操作允许移动用户中断已经建立的语音呼叫，并在随后需要时可以恢复这个呼叫，在中断呼叫期间，网络会保留原有呼叫分配的业务信道；
步骤S304，使用户发起建立新的会议，此时，该用户成为新的会议的主控用户(即被服务用户，主控方)；以及
步骤S306，使用户将这两个会议连接起来。
图4示出了根据本发明方案1的多会议连接装置400。
如图4所示，根据本发明方案1的多会议连接装置400包括：
远端用户分离模块410，用于使用户通过呼叫保持操作，离开其所参与的正在进行的会议，其中，该用户是该会议的远端用户，其驻留在所述软交换网络中的用户设备上；
会议发起模块420，用于使用户发起建立新的会议，此时，该用户成为新的会议的主控用户；以及
连接模块430，用于使用户将这两个会议连接起来。
下面将参照图5到图10，来详细说明根据本发明的方案1的一个实施例。
图5示出了根据本发明方案1的一个实施例的承载模型图；图6到图9分别示出了根据该实施例的各个步骤中的承载模型图；以及图10示出了根据该实施例的信令流程图。
如图5所示，该实施例的模型描述为，在媒体网关(MediaGateway，缩写为MGW)上有MPTY1和MPTY2两个会议，分别对应会议关联CTXmpty1和CTXmpty2，其中用户C为会议MPTY1中的远端用户，该用户作为主控用户发起建立新的会议MPTY2，由用户C选择操作将两个会议连接起来，在网络模型中由CTXmpty1中的端点TC1和CTXmpty2中的端点TC2将两个会议关联连接起来。其中，MGW是核心网络的承载搭建设备，负责具体承载、媒体的搭建、释放和承载资源的管理。
在媒体网关上由主控用户A发起建立一个由用户A、B、C三方参与的会议MPTY1，在通话的过程中，其中一个远端用户C进行呼叫保持操作，离开该会议，并发起建立一个新的会议MPTY2，在该会议中有用户C和用户D参与(可以有更多方的用户参与)。会议MPTY2建立后用户C作为该会议的主控用户(同时用户C还是会议MPTY1的远端用户)，用户C可以选择操作将会议MPTY1和会议MPTY2连接起来。在媒体网关的物理承载上会议的关联CTXmpty1和CTXmpty2通过端点TC和TC1连接起来，这个会议中的用户A、B、C、D能够互相通话。用户C在会议MPTY1中作为远端用户的，在会议MPTY2中作为主控用户。
上面仅描述了两个会议的连接。两个会议中的其它远端用户还能够继续发起建立新的会议，并且同远端用户所在的会议的连接起来，从而实现更大范围的会议业务。
上述网络模型中所描述的两个互连会议位于同一个媒体网关，上述的网络模型可以扩展到多个媒体网关，即每个会议的关联分别可以位于不同的媒体网关上，以通过关联中的端点将关联连接起来，实现会议的连接。
图6示出了根据该实施例的建立由用户A、B、C三方参加的会议的承载模型图；图7示出了根据该实施例的远端用户C发起呼叫保持操作的承载模型图；图8示出了根据该实施例的远端用户C发起建立一个新的会议的承载模型图；以及图9示出了根据该实施例的用户C操作将两个会议连接起来的承载模型图。
如图10所示，远端方用户发起建立新会议的流程如下：
步骤S1002，主控用户发起建立用户A、B、C三方的会议。该过程承载模型参考图6。MSC Server(Mobile Switch Center Server，移动交换中心服务器)向媒体网关下发MOV.Request消息，请求媒体网关创建一个会议的关联。并将已经建立成功的主控用户的端点TA加入到该关联中。网关为该会议分配一个关联(该关联的索引为CTXmpty1)，并将端点加入到该关联中，将分配的关联索引和操作的结果返回给MSC Server。随后MSC Server向媒体网关发送两个MOV.Request消息将建立成功的远端用户B、C的端点TB、TC加入到会议的关联CTXmpty1中，从而建立用户A、B、C三方之间的会议；
步骤S1004，远端用户通过呼叫保持操作，离开正在进行的会议。该过程承载模型参考图7。MSC Server向媒体网关下发MOV.Request消息，请求媒体网关创建一个新的关联，并将远端用户C的端点TC移动到该关联中。网关为该操作分配一个关联(该关联的索引为CTX)，并将端点加入到该关联中，将分配的关联索引和操作的结果返回给MSC Server。这里由于原有的关联中没有端点了，所以网关会将原有的关联释放掉。远端用户C离开了原来建立的会议，在新的关联中能够拨打其他新的用户建立通话；
步骤S1006，远端用户C发起建立一个新的会议。此时，用户C作为新的会议的主控用户。该过程的模型参考图8。MSC Server向媒体网关下发MOV.Request消息，请求媒体网关创建一个新的会议关联，并将已经建立成功的主控用户的端点TC加入到该关联中。网关为该会议分配一个关联(该关联的索引为CTXmpty2)，并将端点加入到该关联中，将分配的关联索引和操作的结果返回给MSCServer。随后MSC Server向媒体网关发送两个MOV.Request消息将建立成功的远端用户D的端点TD加入到会议的关联CTXmpty2中。从而建立起用户C、D两方之间的会议(可以加入更多的用户)。此时的用户C归属于两个会议，在会议一中作为远端用户，在会议二中作为主控用户；以及
步骤S1008，主控用户C发起SPLIT MPTY操作，将这两个关联的会议连接起来。该过程承载模型参考图9。MSC Server向媒体网关下发ADD.Request消息，请求媒体网关在会议一的关联CTXmpty1中建立一个新的端点。网关为该操作分配一个端点索引TC1，并为该端点分配相应的资源，然后将分配的端点索引和操作的结果返回给MSC Server。随后，MSC Server向媒体网关下发ADD.Request消息，请求媒体网关在会议一的关联CTXmpty2中建立一个新的端点，该端点与TC1连接起来。网关为该操作分配一个端点索引TC2，并为该端点分配相应的资源，并与端点TC1连接起来。然后将分配的端点索引和操作的结果返回给MSC Server。这样两个会议的关联通过TC1、TC2连接在一起，两个会议中的用户A、B、C、D能够实现互相通话。
可选地，会议中用户可以按照上述过程完成将更多的会议连接到一起。
下面将参照图11和图12来详细说明根据本发明的方案2。
图11示出了根据本发明方案2的多会议连接方法；图12示出了根据本发明方案1的多会议连接装置1200。
如图11所示，根据本发明方案2的多会议连接方法是通过连接两个已经建立的会议，从而实现将多个会议连接起来，其包括以下步骤：
步骤S1102，使用户a离开其所参与的正在进行的会议a，其中，用户a是会议a中的主控用户，其驻留在所述软交换网络中的用户设备上，可选地，用户a通过呼叫保持操作离开会议a；
步骤S1104，使用户a拨打用户b建立新的呼叫，其中，用户b是已经存在的会议b中的主控用户，其驻留在所述软交换网络中的用户设备上；以及
步骤S1106，使用户a和用户b分别将对方加入其所在的会议a和会议b中，从而将这两个会议连接起来。
图12示出了根据本发明方案2的多会议连接装置1200。
如图12所示，根据本发明方案2的多会议连接装置1200包括：
远端用户分离模块1210，用于使远端用户a离开其所参与的正在进行的会议a，其中，用户a是会议a中的主控用户，其驻留在所述软交换网络中的用户设备上；
呼叫发起模块1220，用于使用户a拨打用户b建立新的呼叫，其中，用户b是会议b中的主控用户，其驻留在所述软交换网络中的用户设备上；以及
连接模块1230，用于使用户a和用户分别将对方加入其所在的会议a和会议b中，从而将这两个会议连接起来。
下面将参照图13到图18，来详细说明根据本发明的方案2的一个实施例。
图13示出了根据本发明方案2的一个实施例的承载模型图；图14到图17分别示出了根据该实施例的各个步骤中的承载模型图；以及图18示出了根据该实施例的信令流程图。
如图13所示，该实施例的模型描述为，在媒体网关上有分别由各自的主控用户A和主控用户D发起建立的会议MPTY1和MPTY2。由MPTY1的主控用户A将用户D加入到会议MPTY1中，由MPTY2的主控用户将用户D将用户A加入到会议MPTY2中，通过端点TG和TH建立两个会议关联之间的连接，将两个会议连起来。
在媒体网关上有两个已经建立的会议。由主控用户A发起建立一个由用户A、B、C三方参与的会议MPTY1；以及主控用户D发起建立的一个由用户D、E、F三方参与的会议MPTY1。
在通话的过程中，其中一个主控用户D进行呼叫保持操作，离开会议，呼叫用户A，并将用户A加入到主控用户D所在的会议。当主控用户A将用户D加入到所在的会议中后。将两个会议连接起来。在媒体网关的物理承载上会议的关联CTXmpty1和CTXmpty2通过端点TG和TH连接起来，处于两个会议中的用户A、B、C、D、E、F能够互相通话。
上面仅描述了两个会议的连接。两个会议中的主控用户还能够继续连接其它的会议，从而实现更大范围的会议业务。
上述网络模型中所描述的两个互连会议位于同一个媒体网关，上述的网络模型可以扩展到多个媒体网关，即每个会议的关联分别可以位于不同的媒体网关上，以通过关联中的端点将关联连接起来，实现会议的连接。
图14示出了根据该实施例的控用户A、D分别建立两个会议的承载模型图；图15示出了根据该实施例的主控用户D呼叫保持后呼叫用户A的承载模型图；图16示出了根据该实施例的主控用户D将用户A加入所在的会议中的承载模型图；以及图17示出了根据该实施例的主控用户A将用户D加入所在的会议中的承载模型图。如图18所示，连接两个已经建立的会议流程如下：
步骤S1802，主控用户A发起建立用户A、B、C三方的会议。该过程承载模型参考图14。MSC Server向媒体网关下发MOV.Request消息，请求媒体网关创建一个会议的关联。并将已经建立成功的主控用户的端点TA加入到该关联中。网关为该会议分配一个关联(该关联的索引为CTXmpty1)，并将端点加入到该关联中，将分配的关联索引和操作的结果返回给MSC Server。随后MSCServer向媒体网关发送两个MOV.Request消息将建立成功的远端用户B、C的端点TB、TC加入到会议的关联CTXmpty1中。建立用户A、B、C三方之间的会议。按照相同的流程主控用户D发起建立D、E、F三方之间的会议；
步骤S1804，主控用户D通过呼叫保持操作离开正在进行的会议，并拨打用户A以建立新的呼叫。该过程承载模型参考图15。MSC Server向媒体网关下发MOV.Request消息，请求媒体网关创建一个新的关联，并将远端用户D的端点TD移动到该关联中。网关为该操作分配一个关联(该关联的索引为CTX)，并将端点加入到该关联中，将分配的关联索引和操作的结果返回给MSC Server。主控用户D离开了原来建立的会议，拨打会议MPTY1中的主控用户A，A选择接通D的呼叫，MSC Server向媒体网关下发MOV.Request消息，要求将会议关联CTXmpty1中的端点TA移动到关联CTX中，将用户D、A接通。网关完成操作后将操作结果返回给MSC Server；
步骤S1806，主控用户D选择将用户A加入到用户D所在的会议MPTY2中，建立D、E、F、A之间的会议业务。该过程的承载模型参考图16。MSC Server向媒体网关下发MOV.Request消息，将主控用户D的端点TD和用户A的端点TA分别移动到会议MPTY2所在的关联CTXmpty2中，建立D、E、F、A之间的会议。网关将TD、TA端点移动到指定的关联后向MSC Server返回操作结果；以及
步骤S1808，会议MPTY1的主控用户A选择将用户D加入到用户A所在的会议中，将会议MPTY1和会议MPTY2连接起来。该过程的承载模型参考图17。MSC Server向媒体网关下发MOV.Request消息，将主控用户A的端点TA移动到会议MPTY1所在的关联CTXmptyA中。收到媒体网关的操作响应后，MSCServer向媒体网关下发ADD.Request消息，请求媒体网关在会议一的关联CTXmpty1中建立一个新的端点。网关为该操作分配一个端点索引TG，并为该端点分配相应的资源，然后将分配的端点索引和操作的结果返回给MSC Server。随后，MSC Server向媒体网关下发ADD.Request消息，请求媒体网关在会议一的关联CTXmpty2中建立一个新的端点，该端点与TG连接起来。网关为该操作分配一个端点索引TH，并为该端点分配相应的资源，并与端点TG连接起来。然后将分配的端点索引和操作的结果返回给MSC Server。这样两个会议的关联通过TG、TH连接在一起，两个会议中的用户A、B、C、D、E、F能够实现互相通话。
可选地，会议中用户可以按照上述过程完成将更多的已经建立的会议连接到一起。
本发明在扩展相关技术的协议的基础上，定义了新的会议连接的网络连接模型和建立流程。该方案的实现包括将同一个媒体网关内的多个会议连接起来；如果会议分布在多个媒体网关中，也能够使用这种方案将这些会议连接起来。
显然，本领域的技术人员应该明白，通过阅读上述的本发明，很容易地可以实现将几个会议中的端点增加到一个关联中，以实现更大范围的用户间的通话过程。
从以上的描述中，可以看出，本发明实现了如下技术效果：
(1)通过移动软交换和媒体网关的配合，实现了会议中远端用户建立新的会议，从而将几个会议级联起来。；
(2)将已经建立的会议连接起来，实现几个会议范围内的用户间双向通信；以及
(3)可以将本发明很容易地推广到分布在多个媒体网关中的多个会议的连接，从而实现更大范围的用户间双向通信。
综上所述，本发明在3GPP协议的基础上对会议过程进行了扩展，完成了基于移动软交换架构下实现了多会议连接的承载模型和实现过程。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。应该明白，这些具体实施中的变化对于本领域的技术人员来说是显而易见的，不脱离本发明的精神保护范围。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
