为了能够在语音通信网络中实现视频通信， 本发明实施例在语音通 信网络中设置视频捆绑业务， 可以用视频捆绑（ B-VIDEO , BIND video ) 表示， 具体为将语音电话捆绑一个视频业务， 用户通过语音通信网络进 行语音通话过程中， 如果需要启动视频通信， 只要开启视频通信即可。
图 1为本发明实施例在语音通信网络中实现视频捆绑的系统一示意 图，假设语音通信网络为 PSTN网络，该系统适用于主叫终端和被叫终端 都具有 PSTN终端， 且位于同一管辖局的情况， 该系统包括： 具备视频通 信功能的终端、 交换机、 中继网关、 软交换机（Softswitch )和归属位置 寄存器（SHLR, smart home location register ) 。 其中， 具备视频通信功 能的终端不仅可以接入 PSTN网络， 即依次连接 PSTN网络中的交换机和 中继网关， PSTN网络中的中继网关通过 SoftS witch使具备视频通信功能 的终端与其他的 PSTN终端或其他语音通信网络的终端进行语音通信；具 备视频通信功能的终端还可以接入 SIP网络， 即直接采用 SIP连接到 SoftSwitch , SoftS witch根据从 SHLR查询的与具备视频通信功能的终端相 关的视频捆绑签约信息实现具备视频通信功能的终端与其他 SIP终端或 其他支持视频功能的终端进行视频通信。
其中， SoftSwitch负责终端的视频捆绑业务的触发、 处理和计费。 中继网关， 负责与 PSTN网络中交换机的交换， 实现 PSTN网络的互 通。
本实施例中的具备视频通信功能的终端， 集成了 PSTN和 SIP可视电 话（SIP可视电话也可以为 H.323等可视电话）， 共用终端的话筒和听筒， 称为融合终端。 当该终端采用 SIP可视电话时，可以在该终端中集成非对 称数字用户环路（ ADSL, Asymetric Digital Subscriber Loop )调制解调 器， 用于当要进行视频通信时， 通过 ADSL调制解调器接入 SIP网络。 由 于该终端可以同时接入 PSTN网络和 SIP网络， 所以具备在两个网络分别 标识自身的 PSTN号码和视频号码， 其中视频号码为视频捆绑业务号码， 一般用户无法感知。
SHLR, 用于保存视频捆绑业务的签约信息， 保存注册了视频捆绑 业务的在 PSTN网络中的主叫号码与在 SIP网络中的视频主叫号码的对应 关系， 在 PSTN网络中被叫终端的被叫号码和在 SIP网络中的视频被叫号 码的对应关系； 为 SoftSwitch提供视频捆绑业务的签约信息查询， 如为 SoftSwitch提供主被叫终端在 PSTN网络的主被叫号码与在 SIP网络中的 视频主被叫号码的对应关系的查询， 提供主被叫终端是否具有视频捆绑 业务的查询。
当然， 视频捆绑业务的签约信息不仅可以保存在 SHLR, 也可以保 存在其他的设备上， 如也可以保存在 SoftSwitch。
在本发明实施例中， Softswitch和中继网关之间可以通过 H248协议 互通， SoftSwitch和 SHLR之间通过生产 自动化协议 （ MAP+ , Manufacturing Automation Protocol )或直径 ( Diameter )十办议互通, 具备 视频通信功能的终端通过电话线与 PSTN网络中的交换机相连接， 采用 SIP与 SoftS witch进行通信。

图 3为本发明实施例在语音通信网络中实现视频捆绑的系统三示意 图，该系统适用于主叫终端和被叫终端中的其中一个具有 PSTN终端，另 一个具有接入网关（AG, Access gateway )终端， 且跨管辖局的情况， 这时， 主被叫终端的视频捆绑业务的签约信息分别存储在不同管辖局的 SHLR中， 不同管辖局都设置 SoftSwitch , SoftSwitch到同一管辖局的 SHLR获取终端的视频捆绑业务的签约信息， 不同管辖局的 SoftS witch之 间通过 SIP进行消息交互， 交互主被叫终端的视频捆绑业务的签约信息。
主被叫终端中的 AG终端在进行语音通信时， 通过 AG和 SoftS witch 接入其他网络，如 PSTN网络。 AG通过媒体网关控制协议（MGCP, Media Gateway Control Protocol ) 、 H248协议或 SIP与 SoftS witch进行消息交互。
图 4为本发明实施例在语音通信网络中实现视频捆绑的系统四示意 图，假设语音通信网络为 PSTN网络，该系统在图 1或图 2的基础上为主叫 终端提供 SIP网络的增值业务， 包括短信、彩信、 网页或信息推送以及短 号上网等业务。 这些业务分别可以由通过 SIP与 Softswitch交互的短信中 心、 彩信中心以及 SIP代理来提供， 其中， SIP代理通过超文本传输协议 ( HTTP, Hypertext Transfer Protocol )与提供不同增值业务的服务提供 商（SP, Service Provider )进行信息交互， 实现网页或信息推送等业务， SIP代理还提供短号到 SIP网络的统一资源定位符 （ URL , Uniform Resource Locator )的转换， 满足主叫终端短号上网的功能； 短信中心具 有短信转发的功能， 彩信中心具有彩信转发的功能。
在图 4中， SIP代理还可以通过筒单对象访问协议（SOAP, Simple Object Access Protocol ) 与网际十办议电视 （IPTV , Internet Protocol Television Video )进行信息交互， 为主被叫终端提供 IPTV和用户的统一 鉴权， 提供与 IPTV互通的 SOAP转换， 为主被叫终端提供 IPTV的功能； SIP代理还可以通过 SIP或 H323协议与流媒体服务器进行信息交互， 为主 被叫终端提供视频捆绑业务的流点播或 /和直播的互通及鉴权功能。
在图 1〜图 4所示的系统中， PSTN终端也可以只具有语音通信功能， 再增加一个具有视频通信功能的终端， 为分离终端， 如电视电话 （TV Phone )与 PSTN终端相连接，具有视频通信功能的终端用于通过 SIP网络 与其他的具有视频通信功能的终端进行视频通信后， 将视频图像传输给 连接的 PSTN终端 （这时， 需要给 PSTN终端设置显示图像功能和通过空 口或其他通信连接传输图像功能） 。 这样， 就实现了主被叫移动终端在 语音通信过程中的视频捆绑业务。
图 5为本发明实施例在语音通信网络中实现视频捆绑的系统五示意 图， 该语音通信网络为移动通信网络， 包括具有语音通信功能的主被叫 移动终端八、 B、 具有视频通信功能的主被叫 TV Phone Al、 Bl、 管辖主 被叫移动终端的移动交换机和中继网关、 管辖主被叫移动终端的 SoftS witch和 SHLR。
其中， 在进行语音通信时， 主叫移动终端发起语音呼叫， 该语音呼 叫通过所属的移动交换机和中继网关接入所属的 SoftSwitch,主叫移动终 端所属的 SoftS witch通过被叫移动终端所属的 SoftSwitch、 被叫移动终端 所属的中继网关和移动交换机接续语音呼叫到被叫移动终端， 进行语音 通信过程。 在进行语音通信过程中， 要进行视频通信， 则主叫移动终端 向主叫 TV PHONE发起视频呼叫、 被叫移动终端向被叫 TV PHONE发起 视频呼叫， 主被叫 TV Phone通过 SIP分别接入所属的 SoftSwitch , 主被叫 TV Phone所属的 SoftS witch访问所属的 SHLR ,获取主被叫 TV Phone的视 频捆绑业务签约信息后， 建立主被叫 TV Phone的视频通信后， 主叫 TV Phone通过空口将视频图像传输给具有显示图像功能和通过空口或其他 通信连接传输图像功能的主叫移动终端， 被叫 TV Phone通过空口将视频 图像传输给具有显示图像功能和通过空口或其他通信连接传输图像功 能的被叫移动终端。 这样， 就实现了主被叫移动终端在语音通信过程中 的视频捆绑业务。
在图 5所示的系统中， 主被叫移动终端所属的 SoftS witch可以为不同 的， 也可以为同一个， 相应地， 存储主被叫移动终端的视频捆绑业务签 约信息的 S HLR可以为一个或两个。 主被叫移动终端也可以集成 TV Phone。
图 1 ~图 5所示的系统中，参与主被叫终端语音通信的 SoftSwitch和参 与主被叫终端视频通信的 SoftSwitch也可以为不同的设备，这时，存储主 被叫终端视频捆绑信息的 SHLR与参与主被叫终端视频通信的 SoftS witch进行信息交互， 为参与主被叫终端视频通信的 SoftS witch提供 主被叫终端视频捆绑信息， 实现主被叫终端的视频通信。 存储主被叫终 端的视频捆绑信息的可以为 SHLR, 也可以为普通的 HLR, 还可以为 SoftSwitch或为其他的设备。
图 6为本发明实施例在语音通信网络中实现视频捆绑的终端，该终端 包括语音通信模块和控制模块， 其中，
语音通信模块， 用于在控制模块的控制下接入语音通信网络， 进行 语音通信；
控制模块， 用于获取视频图像， 进行视频通信， 以及控制语音通信 模块的语音通信。
在该实施例中， 还可以包括视频通信模块， 该模块设置在该终端中 或单独设置，用于接入视频通信网络，通过视频通信网络进行视频通信， 将视频图像提供给控制模块。
举一个具体的实施例进行说明。 图 7为本发明实施例在 PSTN网络中 实现视频捆绑的终端， 该终端集成了语音通信和视频通信功能， 该终端 包括 PSTN通信模块、 控制模块、 视频通信模块以及调制解调器， 其中，
PSTN通信模块， 用于在控制模块的控制下接入 PSTN网络， 通过 PSTN网络进行音频通信；
视频通信模块， 用于在控制模块的控制下通过调制解调器接入视频 通信网络（如 SIP网络 ) , 通过视频通信网络进行视频通信；
控制模块， 用于接收是否进行视频通信的命令， 根据命令控制视频 通信模块和 PSTN通信模块的操作。
以下以视频通信网络为 SIP网络为例进行详细叙述。
当主叫终端和被叫终端都是具备视频通信功能的终端时， 主叫终端 和被叫终端可以分别通过 ADSL调制解调器接入 SIP网络。 主叫终端通过 语音通信网络呼叫被叫终端， 主叫终端显示预先设定的本地图像， 按照 语音通信网络呼叫流程， 主叫终端拨打在语音通信网络中的被叫终端号 码， 该呼叫由交换机和中继网关接续到被叫终端， 被叫终端振铃（或播 放音乐或显示）提示有呼叫呼入， 被叫终端接受呼叫。 被叫终端和主叫 终端进行语音通信， 被叫终端也可以显示预先设定的本地图像。 如果主 叫用户希望进行视频通信， 可以向主叫终端发送视频切换命令， 主叫终 端通过 SIP网络进行视频接续到被叫终端的过程，这时，可以出现以下多 种情况。
第一种情况， 被叫终端预先设置了常开的视频通信， 则主叫终端通 过 SIP网络直接建立与被叫终端的视频通信， 主被叫终端实现视频通信。
第二种情况， 被叫终端预先没有设置常开的视频通信， 则需要使用 被叫终端的用户确认接受本次视频呼叫后，主叫终端再通过 SIP网络建立 与被叫终端的视频通信， 主被叫终端实现视频通信。 如果使用被叫终端 的用户确认不接受本次视频呼叫， 则本次视频呼叫失败， 主叫终端将本 次视频呼叫失败的信息提示给使用主叫终端的用户。
第三种情况，主叫终端通过 SIP网络建立与被叫终端的视频呼叫时失 败（可能因为 SIP网络的原因 ) , 主叫终端将本次视频呼叫失败的信息提 示给使用主叫终端的用户， 继续进行本次语音呼叫。
以下说明主叫终端和被叫终端如何实现视频呼叫的， 过程如图 8所 示， 该过程语音通信功能和视频通信功能集成在一个终端中， 其具体步 骤为：
步骤 801、主叫终端拨打被叫终端在语音通信网络的被叫号码，语音 通信网络中的交换机进行号码的分析， 确定到被叫终端的路由要经过的 SoftSwitch, 将呼叫接续到该 SoftSwitch, 该呼叫携带有主叫终端在语音 通信网络中的主叫号码。
步骤 802、该 SoftS witch接收到呼叫后， 向同一管辖局的 SHLR^送携 带主叫号码的查询视频捆绑业务的查询消息。
步骤 803、 该 SHLR根据存储的视频捆绑业务的签约信息， 确定主叫 终端签约了视频捆绑业务， 向该 SoftSwitch返回所保存的主叫号码在 SIP 网络中对应的视频主叫号码。
步骤 804、 该 SoftS witch接续呼叫到被叫终端， 主被叫终端进入语音 通信状态。
在接续呼叫到被叫终端的过程中， 如果主被叫终端不属于相同的管 辖局，则需要经过被叫终端所属的 SoftSwitch后，再经过被叫终端所属的 中继网关和交换机， 如果主被叫终端属于相同的管辖局， 则只需要经过 被叫终端所属的中继网关和交换机。
步骤 805、 该 SoftSwitch在主被叫终端语音呼叫成功接续后或在接续 过程中，通过 SIP网络向主叫终端发送视频捆绑业务注册回呼，该呼叫中 携带主叫号码、 原被叫号码（就是本次语音通信所使用的被叫号码）和 用视频捆绑业务标识的视频主叫号码。
该回呼在 SIP网络中接续到主叫终端，主叫终端注册具有视频主叫号 码的视频捆绑业务后 （通过调制解调器接入 SIP网络进行注册） ， 向该 SoftS witch返回释放本次回呼的消息。
此时， 主叫终端对接入 SIP网络的状态进行监控， 即记录上网和注册 的状态。
用视频捆绑业务标识的视频主叫号码可以为 *56 +视频主叫号码，即 视频捆绑业务标识为一个接入码 *56。 本次回呼为一个虚拟呼叫， 用于 将语音通信的主被叫号码提供给具有视频主叫号码的主叫终端， 主叫终 端根据语音通信的主被叫号码建立在 SIP网络中的视频通信，为了标识该 虚拟呼叫， 可以用视频捆绑业务标识视频主叫号码。
步骤 806、 主叫终端通过 SIP网络向其所属 SoftSwitch发起视频呼叫， 该呼叫可以为访问 （INVITE ) 消息， 携带视频捆绑业务标识。
步骤 807、 主叫终端所属的 SoftSwitch接收到 INVITE消息后， 触发视 频捆绑业务， 用原被叫号码（就是本次语音通信所使用的被叫号码）替 换携带的视频捆绑业务标识后， 向被叫终端发起视频呼叫。
在该步骤中， 如果该 SoftSwitch不是被叫终端所属的 SoftSwitch, 发 送给被叫终端的 INVITE消息还需要经过被叫终端所属的 SoftSwitch。
步骤 808、主叫终端所属的 SoftSwitch向同一管辖局的 SHLR发送查询 被叫终端的视频捆绑业务的查询消息， 该消息携带原被叫号码（就是本 次语音通信所使用的被叫号码） 。 该 SHLR根据存储的视频捆绑业务的 签约信息，确定被叫终端签约了视频捆绑业务，向该 SoftS witch返回所保 存的原被叫号码在 SIP网络中对应的视频被叫号码。
在该步骤中， 如果该 SoftSwitch不是被叫终端所属的 SoftSwitch, 则 在同一管辖局的 SHLR中也不会存储被叫终端的视频捆绑业务的签约信 息，需要和被叫终端所属的 SoftSwitch进行消息交互， 由被叫终端所属的 SoftSwitch到同一管辖局的 SHLR中获取对应的视频被叫号码， 提供给主 叫终端所属的 SoftSwitch。
步骤 809、主叫终端所属的 SoftS witch在 SIP网络中通过视频被叫号码 呼叫被叫终端， 即向被叫终端发送携带视频被叫号码的 INVITE消息（在 主叫终端所属的 SoftSwitch和被叫终端所属的 SoftSwitch为不同实体时， 还通过被叫终端所属的 SoftSwitch发送） ， 当被叫终端返回成功应答时， 主叫终端确定已经通过 SIP网络成功与被叫终端建立了视频通信，主叫终 端通过 SIP网络与被叫终端进行视频通信； 当被叫终端无法接入 SIP网络 或者不接受本次视频通信时， 被叫终端不返回应答或返回失败应答， 则 主叫终端通过 SIP网络无法与被叫终端建立视频通信。
当被叫终端无法接入 SIP网络时， 可以在被叫终端所属的 SoftSwitch (可以与主叫终端所属的 SoftSwitch为同一实体或不同实体） 发送 INVITE消息时设置定时器，在定时器达到设定值时没有接收到应答， 则 再重新发送 INVITE消息或确定主叫终端通过 SIP网络无法与被叫终端建 立视频通信。
步骤 810、 主叫终端进行视频通信到语音通信的过程， 通过 SIP网络 向所属 Softswitch发送携带视频主叫号码的释放 ( BYE )消息请求释放视 频呼叫， 携带视频主叫号码， 该 SoftS witch接收到 BYE消息后， 根据视频 主叫号码拆除主叫终端通过 SIP网络建立的与被叫终端的视频通信。
在本步骤中， 拆除视频通信时主叫终端在步骤 805接入 SIP网络时的 注册信息并不会注销。
步骤 811、 主叫终端通过语音通信网络拆除与被叫终端的语音通信。 在主叫终端拆除与被叫终端的语音通信时，需要通过 SIP网络向所属 SoftSwitch发送携带视频主叫号码的瞬间注销呼叫， 所属 SoftSwitch清空 主叫终端的注册信息。
图 8所述的方法为主叫终端发起视频通信的过程，在主被叫终端进行 语音通信时， 被叫终端也可以发起视频通信过程， 整个过程和主叫终端 发起视频通信的过程相同。
在本发明实施例中， 终端的视频通信功能和语音通信功能也可以不 集成在同一个实体上， 而是分别在两个实体上实现。 这时， 步骤 801 ~ 804都是具有语音通信功能的主被叫实体完成； 在步骤 805中， 进行虚拟 呼叫时， 需要具有语音通信功能的主叫实体虚拟呼叫具有视频通信功能 的主叫实体； 在步骤 806 - 810中， 基本上是由具有视频通信功能的主被 叫实体完成； 步骤 811是由具有语音通信功能的主被叫实体完成。
在本发明实施例中，控制语音通信过程的主叫终端所属的 SoftSwitch 和控制视频通信过程的主叫终端所属的 SoftS witch也可以不是同一个实 体， 而是两个不同的实体。 同样地， 控制语音通信过程的被叫终端所属 的 SoftSwitch(可以与主叫终端所属的 SoftSwitch为一个实体或不同实体） 和控制视频通信过程的被叫终端所属的 SoftS witch(可以与主叫终端所属 的 Softswitch为一个实体或不同实体）也可以不是同一个实体， 而是两个 不同的实体。
在本发明实施例中， 当语音通信网络为 PSTN网络时， 主被叫终端可 以为具有视频通信功能的 PSTN终端、或者为 PSTN终端和视频通信终端； 当语音通信网络为移动通信网络时， 主被叫终端可以为具有视频通信功 能的移动终端、 或者为移动终端和视频通信终端。
以下以图 1和图 2所示的系统分别为例说明主叫终端和被叫终端实现 视频呼叫的消息交互过程。
其中，以图 1所示的系统为例说明主叫终端和被叫终端实现视频呼叫 的消息交互过程如图 9所示， 其中主被叫终端都签约了视频捆绑业务， 主被叫终端都具有语音通信功能和视频通信功能， 即属于融合终端呼叫 融合终端的情况，主被叫终端属于同一个 SoftS witch管辖，其具体步骤为： 步骤 901、 SoftS witch接收到主叫终端通过语音通信网络发送的呼叫 建立消息， 检查主叫中继网关和主叫终端的配置， 到 SHLR查询主叫终 端是否签约了视频捆绑业务， 通过语音通信网络接续呼叫到被叫终端。
步骤 901中的具体过程为：
步骤 9011、 SoftS witch接收到主叫终端通过语音通信网络发送的初始 地址消息（IAM, Initial Address Message ) , 按照现有技术启动号码分 析得到主叫号码， 到 SHLR查询主叫号码是否签约了视频捆绑业务， SHLR返回主叫终端签约了视频捆绑业务的查询响应消息。
在本步骤中， 需要扩展该 SoftSwitch与 SHLR之间的接口。
该 SoftS witch通过语音通信网络接续呼叫到被叫终端， 即通过 ANM 消息向被叫终端上报摘机信号，该 SoftSwitch接收到应答信号后，接续主 被叫终端， 即进行主被叫终端的语音通信过程。 步骤 902、 该 SoftSwitch对应于视频主叫号码触发视频捆绑回呼的业 务， 由于同时支持被叫终端的接口， 需要给被叫号码对应的视频被叫号 码设置视频捆绑回呼的业务， 由于与触发视频捆绑回呼的业务相同， 所 以这里就不再叙述。
步骤 902的具体过程为：
步骤 9021、 该 SoftSwitch通过在主叫号码前插视频捆绑业务标识到 SHLR查询主叫号码对应的视频主叫号码， 在主叫号码前插视频捆绑业 务标识就是携带主叫号码的查询视频捆绑业务的查询消息。
在本步骤之后， 该 SoftS witch通过 SIP网络向主叫终端发送视频捆绑 业务注册回呼， 该呼叫中携带主叫号码、 原被叫号码（就是本次语音通 信所使用的被叫号码）和用视频捆绑业务标识的视频主叫号码。
该回呼在 SIP网络中接续到主叫终端，主叫终端注册具有视频主叫号 码的视频捆绑业务后， 向该 SoftS witch返回释放本次回呼的消息。 这样， 在该 SoftS witch将本次语音通信所使用的主被叫号码提供给了具有视频 通信功能的主叫终端。
步骤 9022、 该 SoftSwitch确认在步骤 901已经建立主叫终端通过语音 通信网络与被叫终端的通信。
步骤 9023、 主叫终端发送视频切换命令， 即通过 SIP网络向该 SoftSwitch发送 INVITE消息， 该 SoftSwitch触发视频捆绑回呼。
步骤 9024、 该 SoftSwitch通过视频捆绑业务标识和被叫号码到 SHLR 查询到被叫号码对应的视频被叫号码。
步骤 9025、 该 SoftSwitch通过 SIP网络发送携带视频被叫号码的 INVITE消息， 被叫终端通过 SIP网络接收到后进行应答。
步骤 9026、 该 SoftS witch通过 SIP网络发送携带视频主叫号码的消息 给主叫终端，接收到主叫终端的应答消息后，通过 SIP网络建立主叫终端 和被叫终端之间的视频通信。
在图 9的步骤 9011中的到 SHLR查询主叫号码是否签约了视频捆绑 业务的具体过程为：
在 SHLR中， 如果主叫终端没有注册视频捆绑业务， 则 SHLR可以直 接返回主叫终端没有注册视频捆绑业务的消息给该 SoftSwitch , 该 Softswitch按照普通的呼叫处理， 后续关于视频捆绑业务的流程不进行。
在 SHLR中， 如果主叫终端注册了视频捆绑业务和增值业务， SHLR 根据设置的业务优先顺序返回对应的业务标识给该 SoftSwitch , 该 SoftSwitch进行相关的业务处理， 当接收到视频主叫号码时，分析视频主 叫号码并进行后续关于视频捆绑业务的过程。
在图 9中的步骤 9021的具体过程为：
如果 SHLR接收到的查询消息携带的不是视频捆绑标识和主叫号 码， 则确认为一个语音通信网络呼叫， 在对主叫号码对应的查询中， 不 返回视频捆绑业务标识。
在 SHLR中， 当主叫终端没有注册视频捆绑业务时， SHLR返回主叫 终端没有注册视频捆绑业务的消息后， 该 SoftSwitch为主叫终端释放在 SIP网络中的注册资源。 当主叫终端注册视频捆绑业务时， SHLR返回视 频主叫号码后， 该 SoftSwitch进行后续关于视频捆绑业务的过程。
在图 9中的步骤 9023的具体过程为：
如果主叫终端没有发送视频切换命令， 则不进行后续过程； 发送视 频切换命令， 则进行后续过程。
在图 9中的步骤 9024的具体过程为：
如果 SHLR接收到的查询消息携带的不是视频捆绑标识和被叫号 码， 则在对被叫号码对应的查询中， 不返回视频捆绑业务标识。
在 SHLR中， 当被叫终端没有注册视频捆绑业务时， SHLR返回被叫 终端没有注册视频捆绑业务的查询响应消息，该 SoftS witch为被叫终端释 放在 SIP网络中的注册资源。 当被叫终端注册视频捆绑业务时， SHLR返 回视频被叫号码后， 该 SoftS witch进行后续关于视频捆绑业务的过程。
在图 9中的步骤 9025的具体过程为：
如果在 SIP网络中的被叫终端忙或没有注册上， 则该 SoftS witch给主 叫终端发送相应的原因值；
如果被叫终端不支持视频捆绑业务，则该 SoftS witch直接释放本次视 频呼叫， 释放原因表明被叫终端不支持视频呼叫。
如果该 SoftSwitch接收到被叫终端的未注册视频捆绑业务的消息或 忙等信息， 则启动定时器， 在定时器超时后重复上述的过程， 在 SIP网络 中呼叫被叫终端， 这个过程执行设定的次数， 如三次， 每次时间间隔为 10秒， 如果整个过程进行完后为失败， 则提示失败。
如果该 SoftSwitch接收到被叫终端的不支持视频呼叫，则为被叫终端 释放在 SIP网络中的注册资源。
如果在这个过程中， 主叫终端通过 SIP网络发送视频通信失败消息， 则结束视频呼叫， 提示本次视频呼叫失败。
以图 2所示的系统为例说明主叫终端和被叫终端实现视频呼叫的消 息交互过程图 10所示， 其中主被叫终端都签约了视频捆绑业务， 主被叫 终端都具有语音通信功能和视频通信功能， 即属于融合终端呼叫融合终 端的情况， 主被叫终端不属于同一个 SoftSwitch管辖， 其具体步骤为： 步骤 1001、主叫终端所属的 SoftSwitch接收到主叫终端通过语音通信 网络发送的 IAM 消息， 按照现有技术启动号码分析， 到同一管辖局的 SHLR查询主叫号码的是否签约了视频捆绑业务， 该 SHLR返回主叫终端 签约了视频捆绑业务的查询响应消息。
在本步骤中， 需要扩展主叫终端所属的 SoftSwitch与同一管辖局的 SHLR之间的接口。
主叫终端所属的 SoftS witch通过被叫终端所属的 SoftS witch接续呼叫 到被叫终端， 即通过 ANM消息向被叫终端上报摘机信号， 主叫终端所属 的 SoftS witch接收到被叫终端通过所属的 SoftSwitch发送的应答信号后， 通过被叫终端所属的 SoftS witch接续主被叫终端，即进行主被叫终端的语 音通信过程。
步骤 1002、主叫终端所属的 SoftSwitch对应于视频主叫号码触发视频 捆绑回呼的业务。 由于同时支持被叫终端的接口， 需要给被叫号码对应 的视频被叫号码设置视频捆绑回呼的业务， 由于与触发视频捆绑回呼的 业务相同， 所以这里就不再叙述。
步骤 1002的具体过程为：
步骤 10021、 主叫终端所属的 SoftSwitch通过视频捆绑业务标识和主 叫号码到管辖主叫终端的 SHLR查询， 通过视频捆绑业务标识和主叫号 码到管辖主叫终端的 SHLR查询就是发送携带主叫号码的查询视频捆绑 业务的查询消息。 由于在管辖主叫终端的 SHLR没有主叫号码对应的视 频主叫号码， 因此需要到被叫终端所属的 SHLR查询对应的视频主叫号 码。
在本步骤之后， 该 SoftSwitch通过 SIP网络向主叫终端发送视频捆绑 业务注册回呼， 该呼叫中携带主叫号码、 原被叫号码（就是本次语音通 信所使用的被叫号码 )和用视频捆绑业务标识的视频主叫号码。
该回呼在 SIP网络中接续到主叫终端，主叫终端注册具有视频主叫号 码的视频捆绑业务后， 向该 SoftS witch返回释放本次回呼的消息。 这样， 在该 SoftS witch将本次语音通信所使用的主被叫号码提供给了具有视频 通信功能的主叫终端。
步骤 10022、 主叫终端所属的 SoftSwitch确认在步骤 1001经被叫终端 所属的 SoftS witch建立主叫终端通过 PSTN网络与被叫终端的通信。
步骤 10023、 主叫终端发送视频切换命令， 即通过 SIP网络向所属
SoftSwitch发送 INVITE消息， 该 SoftSwitch触发视频捆绑回呼。
步骤 10024、 主叫终端所属的 SoftSwitch通过视频捆绑业务标识和被 叫号码经被叫终端所属的 SoftS witch到管辖被叫终端的 SHLR查询到被 叫号码对应的视频被叫号码。
步骤 10025、主叫终端所属的 SoftS witch通过 SIP网络经被叫终端所属 的 SoftS witch发送携带视频被叫号码的 INVITE消息，被叫终端通过 SIP接 收到后进行应答。
步骤 10026、主叫终端所属的 SoftSwitch通过 SIP发送携带视频主叫号 码的消息，接收到主叫终端的应答消息后，通过 SIP网络建立主叫终端和 被叫终端之间的视频通信。
在步骤 1001中的到 SHLR查询主叫号码是否签约了视频捆绑业务的 具体过程为：
在主叫终端所属的 SHLR中， 如果主叫终端没有注册视频捆绑业务， 则 SHLR可以直接返回主叫终端没有注册视频捆绑业务的消息给主叫终 端所属的 SoftSwitch, 主叫终端所属的 SoftSwitch按照普通的呼叫处理， 后续关于视频捆绑业务的流程不进行。
在主叫终端所属的 SHLR中， 如果主叫终端注册了视频捆绑业务和 增值业务， SHLR根据设置的业务优先顺序返回对应的业务标识给主叫 终端所属的 SoftSwitch,主叫终端所属的 SoftSwitch进行相关的业务处理， 当接收到视频主叫号码时， 分析视频主叫号码并进行后续关于视频捆绑 业务的过程。
在步骤 10021中的具体过程为：
如果主叫终端所属的 SHLR和被叫终端所属的 SHLR接收到的查询 消息携带的不是视频捆绑标识和主叫号码， 则确认为一个语音通信网络 呼叫， 在对主叫号码对应的查询中， 不返回视频捆绑业务标识。
在主叫终端所属的 SHLR和被叫终端所属的 SHLR中， 当主叫终端没 有注册视频捆绑业务时， 返回主叫终端没有注册视频捆绑业务的消息， 主叫终端所属的 SoftSwitch为主叫终端释放在 SIP网络中的注册资源。 当 主叫终端注册视频捆绑业务时， 返回视频主叫号码后， 主叫终端所属的 SoftS witch进行后续关于视频捆绑业务的过程。
在图 10中的步骤 10023的具体过程为：
如果主叫终端没有发送视频切换命令， 则不进行后续过程。
在图 10中的步骤 10024的具体过程为：
如果被叫终端所属的 SHLR接收到的查询消息携带的不是视频捆绑 标识和被叫号码，则在对被叫号码对应的查询中，不返回视频捆绑业务。
在被叫终端所属的 SHLR中， 当被叫终端没有注册视频捆绑业务时， 该 SHLR返回被叫终端没有注册视频捆绑业务的消息， 被叫终端所属的 SoftS witch为被叫终端释放在 SIP网络中的注册资源。 当被叫终端注册视 频捆绑业务时， 该 SHLR返回视频被叫号码后， 被叫终端所属的 SoftS witch进行后续关于视频捆绑业务的过程。
在图 10中的步骤 10025的具体过程为：
如果在 SIP网络中的被叫终端忙或没有注册上， 则被叫终端所属的 SoftSwitch经主叫终端所属的 SoftSwitch通过 SIP网络给主叫终端发送相 应的原因值；
如果被叫终端不支持视频捆绑业务， 则被叫终端所属的 SoftSwitch 直接释放视频呼叫， 释放原因表明被叫终端不支持视频呼叫。
如果被叫终端所属的 SoftS witch接收到被叫终端的未注册视频捆绑 业务的消息或忙等信息， 则启动定时器， 在定时器超时后重复上述的过 程， 在 SIP网络中呼叫被叫终端， 这个过程执行设定的次数， 如三次， 每 次时间间隔为 10秒， 如果整个过程进行完后为失败， 则提示失败。
如果被叫终端所属的 SoftS witch接收到被叫终端的不支持视频呼叫， 则为被叫终端释放在 SIP网络中的注册资源。
如果在这个过程中， 主叫终端通过 SIP网络发送视频通信失败消息， 则结束视频呼叫， 提示视频呼叫失败。
在本发明实施例中， 主被叫终端的视频捆绑业务的签约信息也可以 不存储在 SHLR中， 而是存储在设置的数据服务器或 Softswitch中的数据 库中， 这时， 需要建立 SoftSwitch和设置的数据服务器或 SoftSwitch中的 数据库的扩展接口， SoftSwitch获取主被叫终端的视频捆绑业务的签约信 从图 9和图 10可以看出，为了使 SoftSwitch可以查询 SHLR中存储的主 被叫终端的视频捆绑业务的签约信息， 需要在 SoftSwitch和 SHLR之间扩 展接口支持视频捆绑业务的签约信息查询。
本发明实施例有两种在 SoftS witch和 SHLR之间扩展接口支持视频捆 绑业务的签约信息查询的方法， 以下分别进行详细说明。
第一种方法
在主叫终端通过 SIP网络视频呼叫被叫终端时，由于主叫终端和被叫 终端的视频呼叫为 SIP网络的呼叫， 按照 SIP网络的现有规定， 需要进行 主被叫签约业务的查询， SHLR会返回主被叫终端签约业务标识， 包括 主被叫终端视频捆绑业务的标识和视频主叫号码（这时需要查询视频被 叫号码， 主被叫终端跨 SHLR, 则通过主叫终端所属的 SoftSwitch和被叫 终端所属的 SoftS witch之间的 MAP+交互信息， 查询得到）。 对于被叫终 端， 也可以在呼叫的过程中预先不进行视频捆绑业务的查询， 在 SHLR 完成所有管辖终端的签约业务查询后， 并不返回被叫终端的视频被叫号 码， 如果 SoftS witch发起注册 /注销 /视频切换呼叫时， 则可以通过视频捆 绑业务标识通知 SHLR, SHLR直接返回视频主被叫号码， 不进行其他查 询。
图 11为本发明实施例查询 SHLR中存储的视频捆绑业务的签约信息 的方法一流程图， 其具体步骤为：
步骤 1101、 SoftSwitch到 SHLR中查询获取主叫终端的视频捆绑业务 的签约信息， 该查询消息携带主叫号码。
步骤 1101的具体过程为：
a ) 按照现有技术触发 SHLR得到主叫 "SHLR选择源码" 和被叫 "SHLR选择码" ， "SHLR选择源码" 可以从 SHLR存储的呼叫源表中 获得， 采用 SIP网络的现有技术， 只是增加了一种主叫类业务， 即视频捆 绑业务；
b )如果 SHLR返回了视频捆绑业务标识， 则表明主叫终端签约了视 频捆绑业务， SoftS witch进行号码分析，并将视频捆绑业务标识在号码分 析中进行配置， 配置为视频捆绑权限接入码， 然后使用被叫号码进行接 续；
c )如果 SHLR没有返回视频捆绑业务标识， 则表明主叫终端没有签 约视频捆绑业务。
d )其他异常处理， 与现有技术中的 SIP网络处理业务相同。
步骤 1102、 在主叫终端和被叫终端通过语音通信网络进行语音通话 过程中， 主叫终端通过 SIP网络向 SoftSwitch发送携带原被叫号码的 INVITE消息， 则在 SIP网络中呼叫被叫终端， 建立视频通信。
步骤 1102的具体步骤为：
a ) SoftS witch访问 SHLR。
b )通过调用 "被叫视频查询接口" 上 SHLR查询 （根据步骤 1101中 的 a )得到的 "SHLR选择源码" 和 "SHLR选择码" 触发 SHLR查询） ， 获取被叫终端的视频被叫号码， 在查询消息中需要携带主被叫号码和视 频捆绑标识， 保证 SHLR只返回视频主被叫号码， 而不进行其他业务的 查询。
如果 SHLR返回了视频主被叫号码， 则根据该号码建立视频通信； 如果 SHLR没有返回视频主被叫号码， 则无法建立视频通信。
在 SHLR中， 为了实现本发明实施例， 需要：
1、建立号码与视频号码的对应关系，如建立主被叫号码对应到视频 主被叫号码的视频捆绑业务表格， 可以对该表格中的表项进行增加、 删 除、 爹改和查询。
2、 接收到 SoftSwitch发送的携带主被叫号码和视频捆绑业务标识的 消息后， 查询建立的对应关系后， 得到对应于被叫号码的视频被叫号码 的查询结果。
3、 SHLR将查询结果采用与 SoftSwitch进行消息互通的协议， 如 MAP+封装， 发送给 SoftSwitch; 如果没有查询到结果， 则采用 MAP+消 息通知无法查询到。
在本发明实施例中， SoftS witch和 SHLR之间的接口为发送路由信息 ( SRI, Send route information ) , 查询消息为 SRI消息， 方向为 SoftS witch 到 SHLR , 查询响应消息为 SRI响应 （ACK ) 消息， 方向为 SHLR到 SoftSwitch。
其中， SRI消息定义如表 1所示:

该实施例采用扩展的 SHLR接口实现 SoftS witch到 SHLR之间的捆绑 业务查询， 保持了 SIP网络中的接口协议不变化， 减少了 SoftS witch和 SHLR之间的交互次数。
方法二
在本发明实施例中， 为了使 SoftSwitch可以查询 SHLR中存储的视频 捆绑业务的签约信息， 本发明实施例还可以在 SoftSwitch和 SHLR设置私 有传输控制协议（ TCP, Transfer Control Protocol )接口来支持视频的捆 绑业务， 以下进行具体叙述。
在主叫终端呼叫被叫终端时，由于主叫终端和被叫终端是 SIP网络的 呼叫，按照 SIP网络的现有规定， 到 SHLR中进行主叫业务的查询， SHLR 根据存储的主叫终端的主叫业务的签约信息， 依次返回主叫终端的主叫 业务， 包括主叫的视频捆绑业务， 这时， 不需要 SHLR返回视频主叫号 码； 对于被叫终端， 不进行视频捆绑业务的查询， 而是 SHLR在 SIP网络 中的所有被叫签约业务查询完毕后， 不返回视频被叫号码， 如果
Softswitch要触发进行注册 /注销 /视频切换呼叫时， 通过私有 TCP接口给 SHLR发送查询消息， SHLR返回视频主被叫号码， 而不进行其他主被叫 签约的 SIP网络业务的查询。
图 12为本发明实施例查询 SHLR中存储的视频捆绑业务的签约信息 的方法二流程图， 其具体步骤为：
步骤 1201、 SoftS witch通过 SIP网络中现有的接口到 SHLR获取主叫终 端是否签约了视频捆绑业务。
具体过程为：
a )按照现有技术触发 SHLR需要得到主叫 "SHLR选择源码" +被 叫 "SHLR选择码" ， "SHLR选择源码" 从 SHLR中存储的呼叫源表中 获得， 采用 SIP网络的现有技术， 只是增加了一种主叫类业务， 视频捆绑 业务；
b )如果 SHLR返回了视频捆绑业务标识， 则表明主叫终端签约了视 频捆绑业务， SoftS witch进行号码分析，并将视频捆绑业务标识在号码分 析中进行配置， 配置为视频捆绑权限接入码， 然后使用被叫号码进行接 续；
c )如果 SHLR没有返回视频捆绑业务标识， 则表明主叫终端没有签 约视频捆绑业务。
d )其他异常处理， 与现有技术中的 SIP网络处理业务相同。
步骤 1202、 在主叫终端和被叫终端通过语音通信网络进行语音通话 过程中， 主叫终端通过 SIP网络向 SoftSwitch发送 INVITE消息， 则在 SIP 网络中呼叫被叫终端， 建立视频通信。
步骤 1202的具体过程为： a ) SoftS witch访问 SHLR。
b ) SoftSwitch通过 TCP连接发送命令请求查询主叫终端和被叫终端 的视频号码。
c ) SHLR返回响应给 SoftSwitch, 携带主被叫终端的视频号码。 在 SHLR中， 为了实现本发明实施例， 同样需要：
1、建立号码与视频号码的对应关系，如建立主被叫号码对应到视频 主被叫号码的视频捆绑业务表格， 可以对该表格中的表项进行增加、 删 除、 爹改和查询。
2、 接收到 SoftSwitch发送的携带主被叫号码和视频捆绑业务标识的 消息后， 查询建立的对应关系后， 得到对应于主被叫号码的视频被叫号 码的查询结果。
3、 SHLR将查询结果采用与 SoftSwitch进行消息互通的协议， 如 MAP+封装， 发送给 SoftSwitch; 如果没有查询到结果， 则采用 MAP+消 息通知无法查询到。
在该实施例中 , 通过 TCP连接发送的查询请求命令定义为 CMD_REQ, 方向为 SoftS witch到 SHLR, 通过 TCP连接发送的查询请求 命令的响应消息定义为 CMD_RACK, 方向为 SHLR到 SoftS witch。
其中， CMD_REQ定义如表 3所示:
Figure imgf000029_0001
表 3 CMD_ACK定义如表 4所示。
Figure imgf000030_0001
表 4
该实施例采用私有 TCP接口实现 SoftS witch到 SHLR之间的捆绑业务 查询， 实现比较容易且扩展性好。
在本发明实施例中，视频的通信可以采用 IP多媒体子系统（IMS, IP Multimedia Subsystem ) 完成， 这时， SHLR可以替换为归属订阅服务器 ( HSS, Home Subscriber Server ) , 用于存储 IMS用户信息； SoftS witch 可以替换为 IMS服务呼叫会话控制功能 /应用服务器 （ S-CSCF/AS , Serving Call Session Control Functon/Application Server )， 其中 , S-CSCF 执行会话控制功能， 在 IMS核心网中处于核心的控制位置， 负责 UE的注 册鉴权和会话控制， 执行针对主叫端及被叫端 IMS的 UE的基本会话控制 和路由功能， 并根据用户签约的 IMS触发规则， 在条件满足时完成到 AS 的增值业务路由触发以及业务控制交互。
当在 IMS完成视频通信时， 其 HSS的作用和 SIP网络中的 SHLR作用 相似，用于存储终端的视频捆绑业务签约信息并在 S-CSCF/AS 查询时提 供给 S-CSCF/AS; 其 S-CSCF/AS的作用和 SIP网络中的 SoftS witch作用相 似， 用于到 HSS查询所存储的终端的视频捆绑业务签约信息， 并根据查 询得到的信息建立主被叫终端之间的视频通信。 这只是适用的网络不同 而导致的实体名称不同，以上采用 SIP网络实现视频通信的所有实施例都 适用于 IMS。
在本发明中， 可以将 SoftSwitch和 S-CSCF/AS统称为网络设备， 其作 用是查询终端的视频捆绑业务签约信息， 并根据查询得到的信息建立主 被叫终端之间的视频通信。
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。
