Description

一种视频通信方法、 系统及综^某体资源服务器
本申请要求于 2006 年 8 月 11 日提交中国专利局、 申请号为 200610062099.3、 发明名称为"一种视频通信方法及系统"的中国专利申请的优 先权， 其全部内容通过引用结合在本申请中。
技术领域
本发明属于视频通信领域， 尤其涉及一种视频替换的方法、 系统及综合媒 体资源服务器。
背景技术
第三代移动通信网络（ 3G )及下一代通信网络 (NGN)采用软交换为控制核 心， 通过分组交换网作为传输网络， 是可以同时提供话音、 数据、 多媒体等多 种业务的综合性的全开放的网络平台体系。
现有的视频通信技术中，通信双方可以进行视频替换，但是替换的视频是 由用户下载在自己的通信终端中， 然后再发送给对方， 由于通信终端内存的有 限性， 这制约了可替换视频的数量及运营商开展诸如广告等新业务的能力。
当前的 3GPP协议（第三代移动通信合作组织协议）规定了视频电话呼叫 流程， 用于实现 3G用户间的视频呼叫， 但由于 3G网络或用户终端等原因， 3G用户间的视频电话呼叫并不是每次都能够成功， 为此， 3GPP协议也规定了 视频电话呼叫回落规范，在视频电话呼叫失败时提示主叫用户重新发起普通的 话音呼叫。 同时在现有技术中也存在一种视频电话技术，在视频电话呼叫失败 后， 自动重新进行普通语音呼叫。 在这些现有技术中， 当主叫用户发起的视频 电话呼叫失败后， 只能重新发起普通语音呼叫， 不能在直接接通主叫用户和被 叫用户的音频通话的同时， 由系统向主叫用户播放视频，制约了新的通信运营 模式的运用。
发明内容
有鉴于此， 本发明实施例在于提供一种视频通信的方法、 系统及综合媒体 资源服务器， 以提供一种新的视频业务提供方式， 丰富业务的种类。
本发明实施例提供的技术方案如下：
一种视频通信方法， 该方法包括： 在主叫方和被叫方进行音频通话时， 由 综合媒体资源服务器向主叫方和 /或被叫方播放视频。 一种视频通信系统， 该系统至少包括主、被叫通信终端， 还包括综合媒体 资源服务器， 分别与主、被叫通信终端相连接， 用于建立综合媒体资源服务器 和主被叫双方中至少一方通信终端之间的视频通道； 用于存储视频； 用于向主 被叫双方中至少一方通信终端播放视频。
一种综合媒体资源服务器， 包括：
视频存储单元， 用于存储视频；
信息处理单元，用于建立综合媒体资源服务器和主被叫双方中至少一方通 信终端之间的视频通道；用于从所述视频存储单元中提取出视频向所述通信终 端播放。
本发明实施例通过综合媒体资源服务器向主叫方和 /或被叫方播放视频， 避免了在主叫方视频电话呼叫失败后无法接受视频的问题，提供了一种全新的 视频业务实现方式， 为新业务的开展提供了能力。
附图说明
图 1是本发明提供的一种视频通信方法实施例的流程图；
图 2是本发明提供的由综合媒体资源服务器建立主叫方和被叫方音频通 道的一种视频通信方法实施例的流程图；
图 3 是本发明提供的由主叫方建立和被叫方音频通道的一种视频通信方 法实施例的流程图；
图 4是本发明提供的被叫方替换视频的一种视频通信方法实施例的流程 图；
图 5是本发明提供的一种视频通信系统实施例的装置结构示意图图。
具体实施方式
下面结合附图及具体实施例对本发明再作进一步详细的说明。
图 1是一种视频通信方法实施例的流程图，如图 1所示，其具体步骤包括: 步骤 101: 主叫方向被叫方发起视频电话呼叫请求；
步骤 102: 若被叫方不支持视频电话呼叫请求， 建立主叫方和被叫方的音 频通道， 并建立主叫方和综合媒体资源服务器（IMRS ) 的视频通道；
被叫方不支持视频电话呼叫请求是由于被叫方所在的网络不支持视频电 话呼叫请求或者被叫方终端不支持视频电话呼叫请求或者被叫方拒绝视频电 话呼叫请求。
在该步骤 102 中也可以存在以下步驟:首先， 被叫方所在的移动交换中心 将被叫方不支持视频电话呼叫请求的消息发送给综合媒体资源服务器； 然后， 综合媒体资源服务器判断是否进行呼叫回落接管 ,判断的依据可以但不限于是 存储在综合媒体资源服务器中的主叫方定制的记录或者被叫方定制的记录或 者综合媒体服务器设置的指令。如果判断的结果是无需进行视频电话的呼叫回 落接管， 则不建立主叫方和综合媒体资源服务器的视频通道，如果需要进行视 频电话的呼叫回落接管， 则建立主叫方和被叫方的音频通道， 并建立主叫方和 综合媒体资源服务器的视频通道。
建立主叫方和被叫方的音频通道可以通过两种方式：
方式一： 综合媒体资源服务器在收到被叫方不支持视频电话呼叫请求消 息后， 向被叫方发起普通语音呼叫， 建立主叫方与被叫方的音频通道。
方式二： 主叫方接收到被叫方不支持视频电话呼叫请求消息后， 自动进行 普通语音呼叫， 建立主叫方和被叫方的音频通道。
步骤 103: 在主叫方和被叫方进行音频通话时综合媒体资源服务器向主叫 方播放视频。
在综合媒体资源服务器向主叫方播放视频前可以由主叫方或者被叫方决 定向主叫方播放的视频， 或者， 在主叫方和被叫方进行视频通话时， 也可以由 主叫方或被叫方决定向主叫方播放的视频或者修改向主叫方播放的视频。 例 如， 主叫方或者被叫方可以在自己的通信终端的界面上选择所要播放的视频。 当然也可以不通过主叫方或被叫方的选择，而是由综合媒体资源服务器直接向 主叫方播放视频。所播放的视频可以是被叫方定制的视频或者主叫方定制的视 频，也可以是综合媒体资源服务器自动发送的视频。如果综合媒体资源服务器 中同时存储了被叫方定制的视频、主叫方定制的视频和综合媒体资源服务器可 自动发送的视频，或者这三种视频中的任意两种， 综合媒体资源服务器可以按 照优先顺序选择向主叫方播放的视频。
以下举三个具体实施例进一步详细说明该视频通信方法。
图 2是为本发明提供的由综合媒体资源服务器建立主叫方和被叫方音频 通道的一种视频通信方法实施例的流程图， 如图 2所示， 其具体步驟包括： 步骤（1 ): 主叫方终端（MO )拨打被叫方终端（MT )的号码， 发起一个 视频电话呼叫请求， 主叫方所在的移动交换中心 （ 0— MSC )根据被叫用户的 号码向综合媒体资源服务器 （IMRS )发起一个视频电话呼叫， IM S根据被 叫用户的号码向被叫方所在的移动交换中心 （T—MSC )发起一个视频电话呼 叫， T—MSC寻呼被叫方；
步骤（2 ): 被叫方所在的移动交换中心 （T—MSC )发现被叫方无法支持 视频电话呼叫请求， 向 IMRS返回 REL消息 (释放消息)，指示视频电话呼叫失 败；
在该步驟后， 可以直接继续进行下述步骤（3 ), 也可以由综合媒体资源服 务器判断是否继续进行下述步骤（ 3 )，判断的依据是存储在综合媒体资源服务 器中的主叫方定制的记录或者被叫方定制的记录或者综合媒体服务器设置的 指令，如果判断的结果是无需进行视频电话的呼叫回落接管， 则不再进行下述 步骤， 如果需要进行视频电话的呼叫回落接管， 则继续进行以下步骤。
步骤（3 ): IMRS向被叫方终端 （MT )发起一个普通语音呼叫请求； 步驟（ 4 ): 主叫方终端（ MO )和被叫方终端（ MT )通过 IMRS建立音频 通道， 具体步骤可以为：
IMRS 根据被叫用户的号码向 T— MSC发起一个普通语音呼叫请求； T—MSC寻呼被叫方； 当寻呼被叫方成功后， MT向 T—MSC发送 Alerting消息 (振铃消息)； T—MSC收到 Alerting消息后向 IMRS发送 ACM消息 (地址全消息)； IMRS向 0—MSC发送 ACM消息； O— MSC向 MO发送 Alerting消息， 指示被 叫振铃；当被叫摘机后， MT向 T—MSC发送 CONNECT消息 (接通消息)； T—MSC 收到 CONNECT消息时 ,向 IMRS发送 ANM消息（应答消息：); IMRS向 O—MSC 发送 A M消息； O—MSC向 MO发送 CONNECT消息， 指示被叫摘机振铃。
当然， 该步骤不限于此种实现方式， 还可以以其他方式实现。
步骤（ 5): IMRS建立和主叫方 MO的视频通道， 具体步骤可以为： 主叫方 MO采用 H.245协议（负责建立媒体通道：)， 通过 TCS消息（终端 能力集）和 IMRS交互本身支持的能力集选定此次呼叫使用的能力；通过 MSD 消息 (主从确定消息)和 IMRS进行主从确定， 决定此次呼叫中媒体通道的控制 关系； 通过 LMS 消息 (本地复用表发送消息)交换双方的复用表信息； 最终通 过 OLC消息 （逻辑信道信令消息）打开媒体通道， 完成能力协商并建立网络 视频通道。
在主叫方 MO与 IM S的视频通道建立后， 可以直接向主叫方播放视频， 这些视频可以是是被叫方定制的视频或者主叫方定制的视频或者综合媒体资 源服务器自动发送的视频。
当然， 上述步骤（5 )不限于此种实现方式， 还可以以其他方式实现。 此外， 步骤（4 )和步骤（5 )可以同时进行， 也可以先进行步骤（4 ) , 后进行步驟（ 5 ), 或者先进行步骤（ 5 )， 后进行步骤（ 4 )。
这样， 建立了主叫方和被叫方的音频通道、 主叫方和 IMRS的视频通道， 在主叫方和被叫方开始进行音频通话时， 主叫方能看到 IMRS播放的视频。
图 3 是为本发明提供的由主叫方建立和被叫方音频通道的一种视频通信 方法实施例的流程图， 如图 3所示， 其具体步骤包括：
步骤（ 1 ): 主叫方终端 MO拨打被叫方终端 MT的号码，发起一个视频电 话呼叫请求， 主叫方所在的移动交换中心 0_MSC 才 据被叫用户的号码向 IMRS发起一个视频电话呼叫， IMRS根据被叫用户的号码向被叫方所在的移 动交换中心 T— MSC发起一个视频电话呼叫， T— MSC寻呼被叫方；
步骤（2 ): 被叫方所在的移动交换中心 T—MSC发现被叫方无法支持视频 电话呼叫请求， 向 IMRS和 MT返回 REL消息 (释放消息），指示视频电话呼叫 失败； 该视频电话呼叫失败信息被传送给 MO;
步骤（3 ): MO自动向被叫方终端 MT发起一个普通语音呼叫请求， 建立 和 MT的音频通道；
步骤（ 4 ): IMRS在接受到 REL消息后， 建立和主叫方 MO的视频通道。 当然， 步骤 （3 )和步骤 （4 )可以同时进行， 也可以先进行步骤 （3 ) , 后进行步骤（4 )， 或者先进行步驟（4 ), 后进行步骤（3 )。
图 4是为本发明提供的被叫方替换视频的一种视频通信方法实施例的流 程图， 其具体步骤包括：
步骤（ 1：): 主叫方终端 MO拨打被叫方终端 MT的号码，发起一个视频电 话呼叫请求， 主叫方所在的移动交换中心 0—MSC 根据被叫用户的号码向 IMRS发起一个视频电话呼叫， IMRS根据被叫用户的号码向被叫方所在的移 动交换中心 T—MSC 发起一个视频电话呼叫， 被叫方所在的移动交换中心 T—MSC寻呼被叫；
步骤（2 ): 被叫方所在的移动交换中心 T—MSC呼叫被叫方成功后， 建立 主叫方和被叫方的音频通道与视频通道；
具体方法可以是：当被叫方所在的移动交换中心 T—MSC寻呼被叫成功后，
MT向 T— MSC发送 Alerting消息； T— MSC收到从 MT来的 Alerting消息时， 向 IMRS发送 ACM消息； IMRS向 O— MSC发送 ACM消息； OJVISC向 MO 发送 Alerting 消息， 指示被叫振铃； 当被叫摘机后， MT 向 T—MSC发送 CONNECT消息； T—MSC收到从 MT来的 CONNECT消息时， 向 IMRS发送 ANM消息； IMRS向 O— MSC发送 ANM消息； 0— MSC向 MO发送 CONNECT 消息， 指示被叫摘机振铃； 主叫方 MO采用 H.245协议， 通过 TCS消息和被 叫方 MT交互本身支持的能力集并选定此次呼叫使用的能力； 通过 MSD消息 和被叫方 MT进行主从确定，决定此次呼叫中媒体通道的控制关系；通过 LMS 消息交换双方的复用表信息； 最终通过 OLC消息打开收发音频和视频流的通 道，完成能力协商并接通网络； IMRS在中间透传这些消息， 并记录相关信息。
被叫方和主叫方协商完成后， 建立主叫方和被叫方的语音通道与视频通 道， 主叫方和被叫方开始进行音频通话和视频通话；
步骤（3 ): 被叫方决定替换和主叫方交换的视频， 发送 CLC消息给主叫 方， 关闭向主叫方发送视频的通道；
步棘（4 ): IMRS检测到被叫方关闭视频通道后， 根据保留的信息向主叫 方发送 OLC消息， 建立和主叫方的视频通道。
视频通道建立后 IMRS向主叫方播放被叫方定制的视频文件。此时， 主叫 方和被叫方进行音频通话，被叫方看到主叫方的视频，主叫方看到被叫方定制 的视频。
图 4是以被叫方为主叫方定制视频为例进行说明的 , 可以理解，'主叫方也 可以为被叫方定制视频， 即主叫方可以看到被叫方的视频，被叫方看到主叫方 为其定制的视频， 或者， 还可以是主被叫双方都为对方定制视 , 即都关闭向 对方发送视频的通道， 此时， IMRS将和无法接收对方视频的一方建立视频通 道，并给无法接收视频的一方发送视频，当然，如果主被叫双方都关闭则 IMRS 给双方都发送视频。
另外，还一种可能的实现方式是：主叫方向被叫方发起视频电话呼叫请求， 建立主叫方和被叫方的音频通道，建立主叫方和综合媒体资源服务器的视频通 道，建立被叫方和综合媒体资源服务器的视频通道； 在主叫方和被叫方进行音 频通话时， 综合媒体资源服务器向主叫方和被叫方播放视频。
图 5是为本发明提供的一种视频通信系统实施例的装置图，如图所示， 该 系统主要包括主叫方通信终端 11、 综合媒体资源服务器 12、 被叫方通信终端 13, 其中，
综合媒体资源服务器 12， 用于建立综合媒体资源服务器和主被叫双方中 至少一方通信终端之间的视频通道；用于存储视频；用于向通信终端播放视频。
综合媒体资源服务器 12在主叫方通信终端与被叫方通信终端不能建立音 频通道时， 还可以用于建立主叫方通信终端与被叫方通信终端的音频通道。
综合媒体资源服务器可包括信息处理单元 14和视频存储单元 15 , 其中， 信息处理单元 14， 用于建立综合媒体资源服务器和主被叫双方中至少一 方通信终端之间的视频通道；用于从所述视频存储单元中提取出视频向通信终 端播放；
视频存储单元 15, 用于存储视频。
其中， 信息处理单元 14也可以用于建立主叫方通信终端与被叫方通信终 端的音频通道。
主叫方通信终端 11必须有视频电话通信功能。
被叫方通信终端 13可以具有视频电话功能， 也可以没有视频电话功能。 本发明实施例还提供了一种综合媒体资源服务器， 可参见图 5 , 包括： 视频存储单元 15 , 用于存储视频；
信息处理单元 14, 用于建立综合媒体资源服务器和主被叫双方中至少一 方通信终端之间的视频通道；用于从所述视频存储单元中提取出视频向所述通 信终端播放。
上述信息处理单元 14还用于建立主叫方通信终端与被叫方通信终端的音 频通道。
应用本发明实施例， 通过综合媒体资源服务器向主叫方和 /或被叫方播放 视频，避免了在主叫方视频电话呼叫失败后无法接受视频的问题，提供了一种 全新的视频业务实现方式，解决了可替换视频的容量太小，视频通信业务单一， 以及主叫方视频电话呼叫失败后无法接受视频的问题；实现了视频电话呼叫回 落的接管， 提高了视频电话呼叫成功率， 提供了视频替换功能， 为新业务的开 展提供了能力。
总之， 以上所述仅为本发明的较佳实施例而已， 并非用于限定本发明的保 护范围。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。
