下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进 行清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没 有作出创造性劳动前提下所获得的所有其他实施例, 都属于本发明保护的 范围。
方法实施例一
一种基于交互式网络电视(以下筒称 IPTV ) 的信息显示方法, 本实施 例的方法是 IPTV网络中的用户到用户通信弓 )擎所执行的方法,流程图如图 1 所示, 包括:
步骤 101、 当第一用户终端呼叫第二用户终端时, 获取第一用户终端和
/或第二用户终端对应的铃音业务媒体流的标识信息;
可以理解, 本发明实施例的方法适用在基于 IPTV系统的通话过程中, 参考图 2和 3所示, 分别为支持通话业务和不支持通话的 IPTV系统在进行通 话时的结构图, 主要包括 IPTV业务终端和网络端, 其中, IPTV业务终端包 括:
开放式 IPTV功能终端 (以下筒称 OITF ), 具有在管理网络中和非管理 网络中接入 IPTV业务所必需的功能, 例如具备接入 IPTV功能的电视机, 或 者 IPTV机顶盒和旧式电视机等;
网关, 可以是 IP多媒体系统网关(IMS Gateway, IG ), 具有允许 OITF 设备接入管理网络即 IP多媒体系统网络( IMS )中的 IPTV业务所必需的功能, 可以理解为家庭网关中的一个功能模块。
IPTV网络端包括:
认证会话管理实体 ( Authentication and Session Management, ASM ), 主要用于用户终端的接入认证、 会话管理、 并进行计费, 保证用户终端的 业务请求能路由到正确的应用服务器;
用户到用户通信引擎 ( Person-to-Person Communication Enablers , 以下 筒称 Ρ2Ρ Enabler ), 包括不同通信业务的接口, 例如现场( presence ), 聊天 ( chat )、 通知 ( messaging ), 小区标识通知 ( caller ID notification )等, 使 得这些通信业务可以与 IPTV业务结合起来;
播放功能实体, 可以为集群控制器(Cluster Controller, CC ), 主要负 责管理一组内容下发功能实体( Content Delivery Function , CDF ) 的播放, 也可以为 CDF, 主要在 CC的控制下进行负责媒体流的处理、 分发、 播放。
且这里用户终端,是可以发起呼叫的终端即用户设备 ( User Equipment , UE ), 如手机或固定电话等。 在基于支持通话业务的 IPTV系统进行通话时, 各个设备之间的通信, 是按照如图 2所示的连接方式进行通信, 在基于不支 持通话业务的 IPTV系统进行通话时, 各个设备之间的通信, 是按照如图 3 所示的连接方式进行通信。
对于支持通话业务的 IPTV系统,当第一用户终端呼叫第二用户终端时, 第一用户终端发送请求( INVITE ), 该请求通过 IPTV系统中的 ASM传送到 P2P Enabler; 对于不支持通话业务的 IPTV系统, 第一用户终端会在当前所 在网络发起对第二用户终端的呼叫, 发送请求, 而当前呼叫网络会将请求 发送给 IPTV系统中的 P2P Enabler。
可以理解, 这里第一、 第二并不表示顺序的关系, 而是表示两个不同 的用户终端, 也可以理解为主叫终端和被叫终端。
这里所说的铃音业务媒体流可以为回铃音媒体流, 振铃音媒体流, 和 背景音媒体流中任一个或多个, 媒体流的内容可以包括音频、 视频、 文字、 图片及电子名片等多媒体内容, 其中:
回铃音媒体流即多媒体回铃音, 是主叫呼叫被叫时, 在被叫摘机接听 之前, 主叫听到的多媒体回铃音。 目前多媒体回铃音在各大标准组织中的 叫法不同, 在 3GPP中称为个性化回铃音( Customized Alerting Tone, CAT ), 在 ITU-T中称为 CRBT( Customized Ring Back Tone ),在 OMA中称为 CMRBT ( Customized Multimedia Ring Back Tone )。
振铃音媒体流即多媒体彩振, 是主叫拨打被叫时, 在被叫摘机接听之 前,被叫欣赏到的多媒体振铃音。在 3GPP中称为个性化振铃音(Customized Ringing Signal, CRS )CRS,在 ITU-T中称为 CRT( Customized Ringing Tone ), 在 OMA中称为 CMRT ( Customized Multimedia Ringing Tone )。
背景音媒体流即多媒体彩相, 是在主叫和被叫通话过程中, 主被叫双 方都能听到的多媒体背景音。 在 3GPP中称为在个性化背景音(Customized Background Tone , CBT )。
在获取铃音业务媒体流的标识信息如地址信息、 单播类型内容的统一 资源标识符(URL )、 或组播类型内容的组播接入地址等时, 可以通过如下 方法来具体实现: 如果该 IPTV系统支持通话业务, 则 P2P Enabler根据第一 用户终端和 /或第二用户终端的标识信息在本地查找得到对应的铃音业务媒 体流的标识信息, 而本地储存的媒体流的标识信息是在呼叫过程中与用户 终端进行媒体流的协商时储存的; 如果该 IPTV系统不支持通话业务, 则 P2P Enabler可以向当前呼叫网络主动请求获取或接收当前呼叫网络主动下发的 第一用户终端和 /或第二用户终端对应的铃音业务媒体流的标识信息。
可以理解, 当前呼叫网络可以将铃音业务媒体流的标识信息携带在通 知消息中, 并主动发送给 P2P Enabler; 当 P2P Enabler接收到通知消息后, 解 析该通知消息得到铃音业务媒体流业务的标识信息。
步骤 102、将铃音业务媒体流的标识信息发送给第一用户和 /或第二用户 的交互式网络电视业务终端, 以便第一用户和 /或第二用户的交互式网络电 视业务终端根据铃音业务媒体流的标识信息, 获取并播放相应的铃音业务 媒体流。
可以理解,在将铃音业务媒体流的标识信息发送给 IPTV业务终端之前, 需要先查找到第一用户和 /或第二用户对应的 IPTV业务终端标识, 具体地, 在查找时, 可以通过 P2P Enabler将呼叫过程中接收到的请求中的第一用户 和 /或第二用户的用户标识信息, 同本地储存的用户标识信息与 IPTV业务终 端的对应关系进行匹配, 并提取与第一用户和 /或第二用户的用户标识信息 相匹配用户标识信息对应的 IPTV业务终端标识信息来获取的。 其中用户标 识信息是用来唯一标识某一用户的信息, 而业务终端标识信息是用来唯一 标识 IPTV业务终端的信息。
需要说明的是,如果步骤 101中得到的是回铃音媒体流的标识信息, P2P Enabler则将该回铃音媒体流的标识信息发送给第一用户即主叫对应的 IPTV 业务终端; 如果是振铃音媒体流的标识信息, P2P Enabler则将振铃音媒体 流的标识信息发送给第二用户即被叫对应的 IPTV业务终端; 如果是背景音 媒体流的标识信息, P2P Enabler则将背景音媒体流的标识信息发送给第一 和第二用户即主被叫对应的 IPTV业务终端。
且这里所指的某一用户对应的 IPTV业务终端是不包括该用户终端在内 的终端设备, 如电视机、 数码相框等。
当 IPTV业务终端接收到铃音业务媒体流的标识信息时, 如果铃音业务 媒体流的标识信息为单播类型内容的 URL, 则 IPTV业务终端可以将该 URL 作为目的地址, 发起实时流传输协议(RTSP ) 的会话建立和播放过程, 从 而接收下发的 RTSP单播形式的铃音; 如果铃音业务媒体流的标识信息为组 播类型内容的组播接入地址, 则 IPTV业务终端可以根据该组播接入地址接 入相应的组播组, 从而接收下发的组播方式的铃音。
可见, 本发明实施例中的基于交互式网络电视系统的信息播放方法包 括: 当第一用户终端呼叫第二用户终端时, 获取第一用户和 /或第二用户对 应的铃音业务媒体流的标识信息, 并将获取的铃音业务媒体流的标识信息 发送给第一用户和 /或第二用户对应的交互式网络电视业务终端, 以便第一 用户和 /或第二用户的交互式网络电视业务终端根据铃音业务媒体流的标识 信息, 获取并播放相应的铃音业务媒体流。 这样, 在基于 IPTV系统的通话 同时, 在 IPTV业务终端上可以播放通话双方关联的回铃音业务媒体流, 丰 富了通话的内容, 能满足用户的多样需求。
例如, 用户 A将拍摄的照片传到彩铃服务器中, 并将世博会主题曲作 为背景音乐, 然后写上几句游览感言, 这样, 幻灯片 +音乐 +文字就组成了 一首多媒体彩铃。 采用本实施例的方法, 当用户 B在呼叫用户 A的同时, 可以将该多媒体彩铃在用户 B对应的 IPTV业务终端如数码相框、电视机上 播放, 这样丰富了通话的内容。
参考图 4所示, 在一个具体的实施例中, 在执行完步骤 102之后还可 以包括:
步骤 104、 当第一用户终端和第二用户终端开始通话后, 发送摘机消息 给第一用户和 /或第二用户的交互式网络电视业务终端, 以便第一用户和 / 或第二用户对应的交互式网络电视业务终端继续播放, 或暂停播放铃音业 务媒体流, 或将铃音业务媒体流中的音频音量降低或停止播放。
当被呼叫的第二用户终端摘机后, 会发送摘机消息, 该摘机消息会经 过 P2P Enabler, 当 P2P Enabler接收到第二用户终端发送的摘机消息后,将摘 机消息发送给正在播放铃音业务媒体流的 IPTV业务终端; IPTV业务终端接 收到摘机消息后, 可以进行继续播放, 或暂停播放, 或将铃音业务媒体流 中的音频音量降低或停止播放, 这样可以保证用户之间的通话不受干扰。
步骤 105、 当第一用户终端和第二用户终端结束通话时, 发送通话结束 消息给第一用户和 /或第二用户的交互式网络电视业务终端, 以便第一用户 和 /或第二用户对应的交互式网络电视业务终端停止播放铃音业务媒体流。
同样, 当第一用户终端和第二用户终端结束通话时, 即任一用户终端 挂机, 则提前挂机的用户终端会发送通话结束消息, 该通话结束消息会途 经 P2P Enabler, 当 P2P Enabler接收到通话结束消息后, 将通话结束消息发 送给正在播放铃音业务媒体流的 IPTV业务终端; IPTV业务终端接收到通 话结束消息后, 可以停止播放铃音业务媒体流, 同时还可以提示用户将播 放的铃音业务媒体流保存到本地存储器中。
参考 5图所示, 在另一个具体的实施例中, 在执行完上述步骤 102之前 还可以执行步骤 106和 107:
步骤 106、 向第一用户和 /或第二用户对应的交互式网络电视业务终端, 或向第一和 /或第二用户终端发送提示信息, 该提示信息用于提示用户选择 该用户对应的交互式网络电视业务终端作为铃音业务媒体流的转向终端、 或在该用户对应的多个交互式网络电视业务终端中选择一个作为铃音业务 媒体流的转向终端;
这里所指的某一用户对应的 IPTV业务终端是不包括该用户的用户终端 在内的设备, 如电视机、 数码相框等。 即 P2P Enabler可以将提示信息发送 给或第一终端和 /或第二用户终端, 也可以将提示信息发送给电视机、 数码 相框等 IPTV业务终端。
步骤 107、 接收选择的铃音业务媒体流的转向终端的信息后, 执行步骤 102, 将步骤 101中获取的铃音业务媒体流的标识信息发送给选择的铃音业 务媒体流的转向终端。
由于一个用户对应的 IPTV业务终端可能有多个如电视机、个人计算机、 数码相框等, 为了使得只在用户需求的业务终端上播放该媒体流, P2P Enabler可以将 IPTV业务终端的标识信息发送给业务终端或用户终端, 并提 示用户选择其中一个或多个, 这样用户通过业务终端或用户终端选择播放 媒体流的业务终端即铃音业务媒体流的转向终端, 并将该转向终端的信息 如类型标识等发送给 P2P Enabler, 则在执行上述步骤 102时, P2P Enabler是 将铃音业务媒体流的标识信息直接发送给该转向终端。
在其它具体的实施例中, 通过执行步骤 101、 106、 107及 102后转向终 端就接收到 P2P Enabler发送的铃音业务媒体流的标识信息, 之后还可以执 行下述步骤:
步骤 108、 接收选择的铃音业务媒体流的转向终端发送的会话建立请求 消息, 请求建立铃音业务媒体流会话;
步骤 109、 将会话建立请求消息转发给播放功能实体, 如集群控制器或 内容下发功能设备, 在转发的会话建立请求消息中携带当前为第一用户终 端和 /或第二用户终端下发铃音业务媒体流的会话标识, 以便播放功能实体 根据会话标识为第一用户和 /或第二用户对应的交互式网络电视业务终端下 发铃音业务媒体流。
当转向终端接收到铃音业务媒体流的标识信息后, 会发送会话建立请 求消息, 请求建立铃音业务媒体流会话; 当 P2P Enabler接收到会话建立请 求消息后, 将该会话建立请求消息转发给播放功能实体, 并在其中携带会 话标识, 可以理解, 由于用户终端在呼叫过程中, 播放功能实体会通过一 个会话为用户终端下发相应的铃音媒体流, 这是现有的流程, 在这里不进 行叙述, 这里的会话标识就是该会话的标识;
当播放功能实体在接收到转发的会话建立请求消息后, 就可以根据该 会话标识查找到为用户终端下发的铃音业务媒体流, 也可以获得从为用户 终端下发的起始时间到当前时间的时间偏移量, 并将时间偏移量对应的铃 音业务媒体流的内容下发给 IPTV业务终端, 不需要再重新开始播放。
可以理解, 在转向终端发送的会话建立请求消息中可以包括该转向终 端的类型标识, 如电视机类型、 数码相框类型、 个人计算机类型等, 请求 铃音业务流媒体; 这样播放功能实体根据类型标识, 为转向终端发送适合 转向终端播放格式的铃音媒体流, 例如, 转向终端为数码相框的类型, 则 播放功能实体为数码相框下发适合数码相框播放格式的流媒体, 其中播放 格式包括播放像素、 大小等。
需要说明的是, 本实施例中, P2P Enabler与 IPTV业务终端中的电视机、 个人计算机、 数码相框等进行通信时, 需要经过网关; 而 P2P Enabler与用 户终端之间的通信是通过呼叫网络, 或通过 IPTV系统中的 ASM设备。 方法实施例二
一种媒体流显示方法, 本实施例的方法可以是第一或第二用户终端执 行的方法, 流程图如图 6a所示, 包括:
步骤 201、 接收提示消息, 该提示消息用于提示用户选择播放铃音业务 媒体流的交互式网络电视业务终端;
可以理解, P2P Enabler可以发送提示消息给用户终端, 这样用户可以 通过用户终端选择播放铃音业务媒体流的业务终端, 则用户终端在接收到 提示消息后, 用户会选择在对应的交互式网络电视业务终端中选择作为播 放铃音业务媒体流的终端, 即转向终端。
步骤 202、 接收该用户在对应的交互式网络电视业务终端中选择的铃音 业务媒体流的转向终端的信息, 发送用户选择的转向终端的信息给用户到 用户通信引擎, 以便用户到用户通信引擎将相应的铃音业务媒体流的标识 信息, 发送给选择的铃音业务媒体流的转向终端进行播放。
这里某一用户对应的 IPTV业务终端是包括电视机、 个人计算机、 数码 相框等终端, 是可以显示 IPTV系统中运营商提供的信息的终端。
可以理解, 在接收的提示消息中可以包括该用户对应的 IPTV业务终端 的标识,并将提示消息中转向终端的标识发送给 P2P Enabler , 当 P2P Enabler 接收到转向终端的信息后, 可以按照上述步骤 107之后的步骤执行, 如图 5 所示, 在此不再赘述。
可见, 本发明实施例中的媒体流播放方法包括: 接收提示消息, 用于 提示用户选择播放铃音业务媒体流的交互式网络电视业务终端; 接收该用 户在对应的交互式网络电视业务终端中选择的铃音业务媒体流的转向终端 的信息, 发送用户选择的转向终端的信息给用户到用户通信引擎, 以便用 户到用户通信引擎将相应的铃音业务媒体流的标识信息, 发送给选择的铃 音业务媒体流的转向终端进行播放。 这样通过本实施例的方法, 通常在用 户终端上播放的铃音业务媒体流可以转向到该用户对应的 IPTV业务终端 上, 满足了用户对铃音业务媒体流播放的多样需求。
对于任一 IPTV业务终端在进行信息显示时,可以通过如下步骤来实现, 流程图如图 6b所示, 包括:
步骤 203、 接收用户到用户通信引擎发送的铃音业务媒体流的标识信 息;
步骤 204、 发送请求消息给播放功能实体, 请求播放功能实体播放相应 的铃音业务媒体流;
可以理解, 本实施例的方法是在第一用户呼叫第二用户终端的过程中, 由 IPTV系统中的 P2P Enabler发送的第一用户终端和 /或第二用户终端对应 的铃音业务媒体流的标识信息;
业务终端可以发送请求消息给播放功能实体, 且在请求消息中可以携 带铃音业务媒体流的标识信息, 如地址信息等; 当播放功能实体接收到请 求消息后, 会根据铃音业务媒体流的标识信息找到确定的媒体流, 并下发 给业务终端; 业务终端接收到媒体流后进行播放。
业务终端还可以在请求消息中携带业务终端的类型标识, 这样播放功 能实体根据业务终端的类型标识, 向业务终端下发适用于对应的业务终端 播放格式的铃音业务流媒体。
步骤 205、 接收播放功能实体下发的铃音业务媒体流, 并进行播放。 在一个具体的实施例中, 业务终端还可以执行如下步骤:
步骤 206、 接收用户到用户通信引擎发送的摘机消息, 继续播放, 或暂 停播放铃音业务媒体流, 或将铃音业务媒体流中的音频音量降低或停止播 放;
在被叫用户摘机后, 被叫用户终端会发送摘机消息, 摘机消息会经过 P2P Enabler,则 P2P Enabler会发送摘机消息给正在播放铃音业务媒体流的业 务终端, 业务终端接收到该摘机消息后, 会进行相应处理。
步骤 207、 接收用户到用户通信引擎发送的通话结束消息, 停止播放铃 音业务媒体流。
在任一用户挂机后, 该用户终端会发送通话结束消息, 通话结束消息 会经过 P2P Enabler,则 P2P Enabler会发送的通话结束消息给正在播放铃音业 务媒体流的业务终端, 业务终端接收到该通话结束消息后, 会进行相应处 理。
参考图 7所示, 在其它具体的实施例中, P2P Enabler可以先发送提示消 息给业务终端, 让用户通过业务终端来选择在哪个业务终端上播放铃音业 务媒体流; 然后 P2P Enabler再发送铃音业务媒体流的标识信息, 具体通过 如下步骤来实现:
步骤 208、 业务终端接收提示消息, 该提示消息用于提示用户选择播放 铃音业务媒体流的交互式网络电视业务终端;
在接收到提示消息后, 用户会选择在对应的交互式网络电视业务终端 中选择作为播放铃音业务媒体流的终端, 即转向终端。
步骤 209、 业务终端接收该用户在对应的交互式网络电视业务终端中选 择的铃音业务媒体流的转向终端的信息, 发送用户选择的转向终端的信息 给用户到用户通信引擎, 以便用户到用户通信引擎将相应的铃音业务媒体 流的标识信息, 发送给选择的铃音业务媒体流的转向终端进行播放。 这里某一用户对应的 IPTV业务终端是包括电视机、 个人计算机、 数码 相框等终端, 是可以显示 IPTV系统中运营商提供的信息的终端。
可以理解, 在接收的提示消息中可以包括该用户对应的 IPTV业务终端 的标识,并将提示消息中转向终端的标识发送给 P2P Enabler , 当 P2P Enabler 接收到转向终端的信息后, 可以按照上述步骤 107之后的步骤执行, 如图 5 所示, 在此不再赘述。
当用户选择接收提示消息的业务终端为转向终端时, 则业务终端可以 通过步骤 203到 205来进行铃音业务媒体流的显示; 也可以由业务终端来执 行如下的步骤:
步骤 210、 接收用户到用户通信引擎返回的铃音业务媒体流的标识信 息, 发送会话建立请求消息, 请求播放功能实体建立铃音业务媒体流会话 连接;
步骤 211、 接收到播放功能实体发送的响应消息, 该响应消息中携带当 前为用户终端下发铃音业务媒体流的时间偏移量;
可以理解, 业务终端可以发送请求消息给 P2P Enabler, 且在请求消息 中可以携带铃音业务媒体流的标识信息, 如地址信息等; 当 P2P Enabler接 收到请求消息, 可以根据铃音业务媒体流的标识信息, 查找到当前为用户 终端下发的铃音业务媒体流的会话标识, 并携带在请求消息中转发给播放 功能实体;
播放功能实体接收到转发的请求消息后, 会根据会话标识找到相应的 媒体流, 及当前为用户终端下发的铃音业务媒体流的时间偏移量, 即从为 用户终端下发媒体流的起始时间到当前时间的差值; 并将该时间偏移量携 带在响应消息中返回给业务终端。
步骤 212、 发送播放请求消息给播放功能实体, 请求播放功能实体根据 时间偏移量接着发送当前为用户终端下发的铃音业务媒体流;
步骤 213、 接收到下发的铃音业务媒体流, 并进行播放。
业务终端接收到响应消息后, 则发送播放请求消息, 播放功能实体会 根据其中的时间偏移量进行发送媒体流, 这样业务终端就可以不需要从开 始进行播放。 例如: 时间偏移量为 t, 则播放功能实体会得到播放时间 t后的 媒体流内容, 并从该内容开始进行下发媒体流, 这样播放在业务终端的媒 体流不会重复。 可以理解, 业务终端可以在步骤 210中发送的会话建立请求消息中携带 选择的转向终端的类型标识, 请求播放功能实体向转向终端下发适用于类 型标识对应的转向终端播放格式的铃音业务流媒体。 也可以在步骤 212中发 送的播放请求消息中携带选择的转向终端的类型标识, 请求播放功能实体 向转向终端下发适用于类型标识对应的转向终端播放格式的铃音业务流媒 体。
可以理解, 在步骤 203中和步骤 210中接收了铃音业务媒体流的标识信 息后, 在执行步骤 204或步骤 212中发送请求消息给播放功能实体的同时还 可以执行步骤 214:
步骤 214、 发送暂停消息给播放功能实体, 如集群控制器或内容下发功 能设备, 请求播放功能实体暂停下发当前节目; 或发送录制消息给播放功 能实体, 请求播放功能实体对当前节目进行录制。
如果 IPTV业务终端是电视机时, 可能当时正播放电视节目, 而用户终 端进行呼叫时, P2P Enabler下发了铃音业务媒体流的标识信息, 当电视机 收到标识信息后, 可能会打断当前正播放的节目, 为了满足用户不错过对 当前节目, 电视机可以发送录制消息给播放功能实体, 请求录制当前节目, 这样用户通过电视机观看了铃音媒体流后, 就可以请求播放功能实体回放 当前的节目。
而为了使得当前节目不会影响铃音媒体流的播放, 电视机可以发送暂 停消息, 请求播放功能实体暂停下发当前节目。
需要说明的是, 本实施例中 P2P Enabler所执行的方法如实施例一中所 述, 在此不在赘述。 且在基于支持通话业务的 IPTV系统进行通话时, 各个 设备之间的通信, 是按照如图 2所示的连接方式进行通信, 在基于不支持通 话业务的 IPTV系统进行通话时, 各个设备之间的通信,是按照如图 3所示的 连接方式进行通信。 方法实施例三

302、 P2P Enabler在接收到 INVITE消息时, 会根据 A用户的用户标识信 息, 查找到 A用户对应的所有的 IPTV业务终端 (本实施例中筒称为业务终 端) 的类型和终端标识; 且 P2P Enabler根据用户标识信息获得相应的多媒 体彩铃的地址标识即实时流传输协议的统一资源定位符( RTSP URL )。
这里业务终端类型是业务终端的属性, 如电视机类型, 或数码相框类 型等; 而业务终端的终端标识是可以唯一标识业务终端的, 具体可以是全 球可路由用户代理统一资源标识符 (Global Routable User agent URI , GRUU ), 也可以是实例标识(instance ID )等。
可以理解, 用户可以通过客户端提前在 P2P Enabler中设置与用户对应 的业务终端类型, 如果没有设置, 则 P2P Enabler默认为业务终端的类型为 电视机。
303、 在 P2P Enabler的参与下, A用户终端与播放功能实体如 CC&CDF 进行多媒体彩铃的协商。
304、 多媒体彩铃协商完成后, CC&CDF为 A用户终端发送多媒体彩铃。

306、 P2P Enabler还可以同时向业务终端发送相同的提示信息, 此时, 提示信息通过通信消息( MESSAGE )传递到网关, 然后由网关通知给业务 终端, 该通知消息可以使用超文本传输协议成功响应消息(HTTP 200 OK ) 或通用即插即用 (Universal Plug-n-Play, UPnP )通知。
307、 用户 A在 A用户终端上按键确定要将彩铃媒体流转移到电视机 A 上, A用户终端向 P2P Enabler发送携带了双音多频 ( Dual Tone Multi Frequency, DTMF )信号的 INFO消息, INFO消息途经 ASM到达 P2P Enabler。 在 DTMF信号中指明了 A用户选择的转向终端的类型信息即电视机 A的信 308、 P2P Enabler根据 INFO消息中所反馈的转向终端的类型信息即电视 机 A的信息, 选择相应的终端标识即电视机 A的标识。
309、 P2P Enabler根据选择的电视机 A的标识,通过 MESSAGE消息向电 视机 A发彩铃的 URL , 另夕卜, P2P Enabler还可以在 MESSAGE消息中携带彩 铃业务标志, 如可以通过 3GPP的特性标签(feature tag )来实现, 使得 IPTV 业务终端能够得知该 URL是用于播放彩铃的。 MESSAGE消息到达网关后转 换为通知消息发送给电视机 。 地, P2P Enabler在向电视机 A发送 MESSAGE消息时, 在 MESSAGE消息的 接受联系 (accept-contact )头域的值为 " +g.oma. sip-push" , 并在 MESSAGE 消息体中携带彩铃的 URL。
这里电视机 A没有在图中单独画出, 是图中业务终端的一种。
310、 电视机 A收到彩铃的 URL后, 可以向播放功能实体发送实时流传 输协议的暂停消息(RTSP PAUSE )或者实时流传输协议的录制消息(RTSP RECORD ), 以暂停当前的节目或对当前的节目进行录制。
311、 电视机 A发送超文本传输协议(HTTP )的会话建立请求消息, 请 求建立彩铃会话,在 HTTP请求中携带了彩铃的 URL,另外,还可以携带 IPTV 业务终端类型, 如电视机(TV )类型、 移动终端类型、 PC类型、 其他消费 数码终端类型等, 在这里是携带 TV类型; 该请求消息经过网关转换为信令 控制协议(SIP )请求消息, 经由 ASM, 发送到 P2P Enabler。
312、 P2P Enabler在 SIP INVITE消息中携带播放功能实体当前为 A用户 终端下发的彩铃媒体流的 RTSP会话标识( Session-ID ), 然后将 INVITE消息 转发给播放功能实体。
可以理解, 这里的会话标识是在彩铃媒体流协商过程中, 储存在 P2P Enabler中的, 可以才艮据 A用户的用户标识信息查找到。
313、 播放功能实体根据 INVITE消息中的会话标识, 找到已经为 A用户 终端下发的多媒体彩铃, 并得到当前已经播放的时间偏移量, 此时可以停 止为 A用户终端播放。 另外, 播放功能实体还可以根据 INVITE消息中携带 的 "TV类型" 来选择适用于 TV播放内容的格式, 如高清格式的彩铃内容, 并将选择的彩铃内容发送给电视机 A。
314、 播放功能实体返回 200 OK响应消息, 消息中通过范围 (Range ) 头域携带时间偏移量, 该响应消息最终到达电视机 A。
315、 电视机 A向播放功能实体发送播放请求消息(RTSP PLAY ), 并携 带时间偏移量, 以请求开始下发彩铃。
316、 播放功能实体为电视机 A下发多媒体彩铃。
317、 被叫用户 B摘机, B用户终端向 A用户终端发送 200 OK摘机消息, 该消息途经 P2P Enabler、 ASM, 到达 A用户终端。
在这个过程中, 当 P2P Enabler在接收到 200 OK摘机消息时, 会通过 MESSAGE消息向电视机 A发送摘机消息, 该摘机消息经过网关, 转换为通 知消息发送给电视机 。
318、 电视机 A接收到摘机消息后, 可以继续播放或停止播放彩铃, 默 认情况下为继续播放彩铃。
319、 通话结束时, 任一用户挂机, 该用户的用户终端会发送通话结束 消息, 当 P2P Enabler接收到通话结束消息, 会通过 MESSAGE消息向电视机 A发送通话结束消息, 并经过网关转换为通知消息发送给电视机 A。
320、 电视机 A接收到通话结束消息时, 需要停止播放彩铃, 并同时需 要拆掉与播放功能实体之间的 RTSP会话, 即电视机 A发送携带了再见消息
( SIP BYE )的公告( HTTP POST )消息,网关将该消息转换为再见消息( SIP BYE ), P2P Enabler将 SIP BYE消息转发给播放功能实体。 播放功能实体停 止彩铃发送, 并释放相应的资源。
本实施例中上述步骤 302到 308可以省略掉, 从而实现无需用户参与播 放能力实体即可直接将铃音业务媒体流发送到用户对应的的 IPTV业务终端 上。
