Description

互联网协议电视中业务收看的方法和系统 本申请要求于 2011 年 3 月 18 日提交中国专利局、 申请号为 201110066969.5、 名称为 "互联网协议电视中业务收看的方法和系统" 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
本发明涉及互联网协议电视（IPTV )领域。 更具体地说， 本发明涉及互 联网电视中业务收看的方法和系统。 背景技术
IPTV ( Internet Protocol Television )互联网协议电视， 俗称交互式网络电 视， 是在 IP网络上传送包含电视、 视频、 文本、 图像、 数据等， 提供 QoS (服 务质量） /QoE (体验质量）、 安全、 交互性和可靠性的可管理的多媒体业务。 IPTV技术集 Internet, 多媒体、 通信等多种技术于一体， 利用宽带网络作为基 础设施， 以家用电视机、 个人电脑、 手机等作为主要显示终端， 通过 IP协议 向用户提供包括数字电视节目在内的多种交互型多媒体业务。 IPTV最主要的 特点在于它改变了传统的单向广播式的媒体传播方式， 用户可以按需接收， 实 现用户与媒体内容提供商的实时交互， 从而更好的满足用户个性化需求。
IPTV控制功能实体将 IPTV业务分发给授权的用户， 与鉴权和会话管理 ( ASM ) ( Authentication and Session Management )功能实体交互， 路由接收的 和发送的请求消息到正确的目标接收端。 同时完成与 IPTV签约数据和计费相 关实体的交互。
在 IPTV 系统中， 用户可以将用户的签约信息， 存储在 IPTV 业务档案 ( IPTV Service Profile )中。 当用户请求 IPTV业务时， IPTV业务提供商（ IPTV Service Provider )会根据 IPTV 业务档案中的签约信息，来提供业务。 IPTV 业 务档案信息可由业务供应商或其他授权的终端用户来进行更新。 IPTV 业务档 案中存储的签约信息包括： 授权该用户可观看的节目范围； 用户对之前观看的 节目进行设置的书签（Bookmark ), 用户取回该书签后， 可根据此书签， 继续 观看之前观看的节目；用户设置的个性化频道 PCH, 用于订阅自己喜欢观看的 节目。 IPTV 业务档案中还包括用户的偏好信息等功能。
IPTV系统中还定义了一个用户数据库（ User Database ), 用来确保 IPTV 签约用户可以授权接入 IPTV业务平台， 存储一些与 IPTV业务无关的信息， 例如鉴权信息， 通信相关的信息。 IPTV用户的鉴权过程为， 使用 IP多媒体系 统网关 IG ( IMS Gateway ) 中的 IMS子系统用户识别模块（ ISIM )、 通用用户 识别模块（USIM )应用模块（USIM application ) 的鉴权信息， 经由 IG通过 业务平台提供商向 ASM和用户数据库鉴权， 来接入并使用 IPTV业务。
通用集成电路卡 （ UICC ) ( Universal Integrated Circuit Card )卡是一种可 移动智能卡， 它用于存储用户信息、鉴权密钥、 电话簿、短消息等信息。 UICC 可以包括多种逻辑应用， 例如用户标识模块 （ SIM ) ( Subscriber Identity Module )、 通用用户标识模块（ USIM ) ( Universal Subscriber Identity Module )、 IP多媒体业务标识模块（ ISIM, IP Multimedia Service Identity Module )。 当然 UICC还可以包括其它应用 （电子钱包等）。
用户希望使用基于 IMS 的业务， 必须有一个或多个 IMS 私有用户标识
( IMPI )( IMS Private User Identities ),由网络运营商分配，后续用于业务注册、 鉴权、 管理和计费。 IMPI存储在 UICC和 HSS (签约用户归属服务器 Home Subscriber Server ) 中， 标识用户的签约关系， IMPI可用来标识和获取此用户 相关的签约信息。
每个用户可以有一个或多个 IMS公共用户标识 IMPU ( IMS Public User
Identities ), IMPU与 IMPI关联绑定。
现有技术中，用户通过 UICC来鉴权，包括使用 ISIM卡或 USIM application 来鉴权， 获得接入 IPTV业务提供商提供的网络， 使用 IPTV业务提供商网络 提供的 IPTV相关的业务的权限。 用户接入网络后， IPTV业务提供商， 会根 据用户所使用的身份信息， 来获取此用户的 IPTV 业务档案中的签约信息，提 供用户签约的业务。 例如， 当用户在家观看 IPTV业务时， 通过插入的卡， 来 鉴权使用 IPTV业务提供商提供的网络， IPTV业务提供商根据用户卡所绑定 的用户的识别信息， 向用户提供用户签约的业务， 即 IPTV 业务档案中相关的 内容， 比如用户请求设置 Bookmark后,可以通过取回此用户曾经设置的书签， 以便继续观看此节目。 或取回 IPTV 业务档案中设置的此用户的个性化频道 (PCH)的信息， 来观看自己订阅的个性化频道， 偏好节目等。 现有技术中提供 了基本的 Bookmark创建 /存储过程， 和取回 Bookmark过程。
举例来说， 用户在家里有一个 UICC卡， 通过上面的 IMPI来注册使用网 络， 获取签约信息。
在现有技术中， 如果用户不在家时， 例如用户在外地， 或朋友家时， 无法 获取自己已经订购的签约信息， 无法实现通过非家庭中的设备继续观看自己 签约关系相关的内容。 因此考虑如下应用场景举例：
用户 A在家中，通过家中的 UICC签约了 IPTV业务，并设置了一些 IPTV 业务档案相关的信息， 例如对某个内容设置的 Bookmark, 设置的 PCH。 这时 用户 A外出（例如朋友家， 宾馆等）， 用户 A希望用终端 B继续观看自己签约 的 IPTV业务档案中业务信息相关的内容， 享受外出仍然像在家一样的用户体 验， 但不需要自己再次付费网络资源， 而使用朋友家或宾馆的网络资源。
由于目前的签约关系绑定在 UICC 卡上， 而外出使用的终端 B, 提供的 IMPI无法获取用户 A的签约信息，终端 B为非法获取用户 A签约信息的设备， 例如朋友家的终端 B 可以获取朋友的签约信息。 因此， 针对如上的场景， 现 有技术存在无法实现通过终端 B获取用户 A签约数据的功能。
综上， 现有技术存在如下问题：
1. 用户一般通过 UICC认证接入 IPTV业务提供商业务平台，如果用户并 不在家， 而使用其它设备而使用了不同的 UICC, 无法通过其它的 IPTV终端 接入自己签约的 IPTV业务档案信息；
2. 用户如果通过自己的终端观看， 比如外出在宾馆观看时， 无法使用所 在地的 IPTV网络资源和终端， 来观看自己设定的 IPTV 业务档案信息相关的 内容， 例如 bookmark, 个性化频道设定等业务信息， 导致外出不像在家一样 的不好的用户体验。 发明内容

219. 在本发明的一个实施例中， IPTV Control 功能实体进一步完 成确定过程，该确定过程可以包括： 确定 ITF2是否为合法的业务内容接 收终端， ITF2是否设置了播放非 ITF2签约相关内容的偏好， 判断 ITF2 是否有能力显示 IIF1签约的内容等。
220.如果判断为可以，则 IPTV Control向 ITFl返回成功响应消息。 在完成以上过程后，可选的， ITF1用户签约内容的播放可以由以下 两种方式实现：
方式一为网络侧触发在 ITF2 上播放 ITF1用户签约的内容，具体包 括：
221a. 网络侧向 ITF2发起请求， 例如通过推送方式向 ITF2推送
ITF1的业务档案对应的业务内容描述信息或签约的业务内容本身。该业 务内容描述信息可以包括单一签约业务内容的描述信息， 或多个签约内 容的描述信息 （如节目指南）等。 推送的业务内容本身可以是业务档案 中的设定的用户偏好对应的业务内容， 如用户希望接收到的广告等； 222a. ITF2如希望观看网络侧触发推送的内容或内容相关的信息， 则返回响应消息，指示希望观看； ITF2如不希望观看，则返回响应消息， 指示业务终止。 以下流程为用户选择希望继续观看的流程：
223a. ITF2根据接收到的 ITFl的业务档案对应的业务内容描述信 息， 向内容服务器发送业务内容播放消息 （如 RTSP Play消息） ， 向网 络侧指示播放用户根据所述业务内容描述信息选择的相关内容；
224a. 内容服务器返回成功响应消息；
225a. 内容服务器向 ITF2发送相应的内容， 以使 ITF2可以播放相 应的内容；
方式二为终端触发在 ITF2 上播放 ITF1 用户签约的内容， 具体包 括：
221b. ITF2向网络侧发起请求播放相应内容的请求消息，可携带例 如 content id等信息；
222b. IPTV Control功能实体将根据 IPTV 业务档案， 利用功能模 块进行判断， 确认需要发送消息或内容给 ITF2终端；
具体的， IPTV Control功能实体中的判断功能模块将完成的判断可 以包括： 判断 ITF2请求播放的内容为 ITF1用户 IPTV业务签约相关的 内容， 判断 ITF2能力， 根据 ITF2能力发送或转化内容成 ITF2 能播放 的内容， 判断 ITF2为合法终端等判断。
223b. IPTV Control将 ITFl签约的网络电视业务内容发送给 ITF2。 可选的，在业务结束后，即 ITFl不希望继续在 ITF2上继续播放 ITFl 签约的 IPTV业务内容时， 或 ITF2不希望继续播放 ITF1签约的业务时， 可以由 ITF1 , 或 ITF2发送请求消息， 通知 IPTV网络， 暂停此业务， 并 可选的接收网络的响应消息。
实施例一提供的发明方法中，还可以包括， ITF1向 ITF2发送相应的请求 根据 ITF1业务档案信息相 ITF2发送 ITF1签约内容后， ITF2或 IPTV网络根 据此信息， ITF2获取 ITF1签约的内容为在 ITF2本地录制了相应的内容后， 或 IPTV网络侧录制了 ITF1签约的内容后，在时间到来时， ITF2本地提示 ITF1 用户， 或 IPTV网络侧实体可以向 ITF2发送通知消息， 提示用户可播放内容 的场景。 例如， ITF1签约晚上 8点录制一个电视节目， 而 ITF1用户正在 ITF2 上观看另一个节目， ITF2可对节目进行录制， 或 IPTV网络侧完成录制后， 当 时间到来或 ITF1用户进行选择后， 开始播放此录制的节目。 此时， 如果为网 络录制的情况下， 网络侧可发送通知消息给 ITF2 , 通知 ITF2播放此录制的节 目。 该通知也可包含多个录制的节目， 通知 ITF2进行播放节目的选择。
根据本发明的实施例一，可以实现在第二网络电视终端上播放第一网络电 视终端签约的业务内容。 例如， 第一网络电视终端为用户 A的手机， 而第二 网络电视终端为用户 B的电视机， 实施例一可以实现用户 A通过手机触发在 用户 B的电视机上播放用户 A签约的 IPTV内容。提高了用户播放 IPTV内容 的灵活性， 有利于 IPTV内容在不同用户间， 不同类型的终端之间进行转移播 放。
为实现实施例一的技术方案， 本发明实施例提出了一种 IPTV业务内容收 看系统。 图 3A示出了 IPTV业务内容收看系统 30实施例的框图， 所述系统包 括 ASM单元 100; 用于接收请求在 ITF2上播放 ITF1的签约业务内容的请求 消息，其中所述请求消息中携带所述 ITF2的标识； IPTV 业务档案服务器 200, 用于存储 IPTV业务档案； IPTV Control设备 300, 该 IPTV Control设备用于 根据发自 ASM单元 100的所述请求消息， 从 IPTV业务档案服务器 200获取 ITF1的业务档案， 并根据 ITF1的业务档案和 ITF2的标识向 ITF2发送 ITF1 签约的业务内容。
如图 3B所示， 居所述 IPTV业务内容收看系统的一种实施例， IPTV Control设备 300包括： 接收模块 310, 用于从所述 ASM单元 100接收请求消息； 获取模块 320, 用于根据请求消息， 从 IPTV业务档案服务器 200获取 ITF1的业 务档案；发送模块 330,用于根据 ITF1的业务档案和 ITF2的标识向 ITF2发送 ITF1 签约的业务内容。
实施例二
图 4是根据本发明的方法实施例二的流程图，而图 5是根据本发明方法实 施例二的一种可能的实现方式的时序图。 以下结合图 4和图 5并同时参照图 1 至 3具体说明本发明实施例二的方法。 实施例二与实施例一的区别之处在于， 针对选择的具体内容来获取 ITF1的 IPTV业务档案， 在 ITF2上播放所述的具 体内容。 所述具体内容由内容标识 Content id来指示。
实施例二的流程基本上类似于实施例一， 即包括： 在 S410, 接收请求在 第二网络电视终端 ITF2上播放第一网络电视终端 ITF1签约的、 由 Content id 所指示的具体业务业务内容的请求消息。在 S420,根据所述请求消息获取 ITF1 的业务档案和第二网络电视终端 ITF2的标识。 在 S430, 网络侧根据 ITF1的 业务档案向 ITF2发送 ITF1签约的具体业务内容。 在本发明的一个实施例中， S410至 S430的流程中具体包含的具体细节 501至 523b基本类似于实施例一 的具体细节 201至 223b。
实施例二与实施例一相同的部分不再赘述，下面主要描述实施例二与实施 例一不同之处。 实施例二的 S410不同于实施例一的 S110之处在于， 网络侧接 收请求在 ITF2上播放 ITF1签约的， 由 Content id所指示的具体业务内容的请 求消息。 由此， 在 S430, 网络侧根据 ITF1的业务档案向 ITF2发送 ITF1签约 的， 由 Content id所指示的具体业务内容。
结合图 4和图 5, 具体来说， S410包括：
513.用户请求向 ITF2发送 ITF 1签约的业务内容，其中 ITF2是 ITF 1 选定的。
514.向 ASM发送请求将 ITF1签约业务内容发送到 ITF2呈现的请 求消息， 消息中可携带 ITF2标识信息， ITF 1用户标识信息， 内容标识
Content id信息等信息。
515. ASM服务器与 RAC服务器完成资源预留。
516. ASM服务器接收到此请求消息后，将此请求消息转发给 IPTV Control功能实体。
517. IPTV Control功能实体解析此请求消息为请求根据 ITF1用户 的 IPTV Service Profile信息， 向 ITF2发送 ITF1签约的， 由内容标识 Content id指示的内容的请求消息，则进一步获取 ITF1用户的签约信息。
结合图 4和图 5, 具体来说， S430可以包括：
519. IPTV Control根据 ITF1发送的 Content id以及 IPTV 业务档 案信息， 向内容服务器获取相关的内容， 和 /或完成资源协商；
520. 在本发明的一个实施例中， 可以实现 IPTV Control功能实体 进一步确定，该确定过程可以包括确定 ITF2是否为合法的业务内容接收 终端， ITF2是否设置播放非 ITF2签约相关内容的偏好， ITF2是否有能 力显示 IIF1签约的内容等。
521. 如果可以播放， IPTV control功能实体向 ASM发送成功的响 应消息 （ 200 OK消息） ， ASM向 ITF1转发成功的响应消息；
522. ASM与 RAC(Resource and Admission Control)服务器确认资源 预留， 例如预留足够的带宽；
523. IPTV Control功能实体向 ITF2发送请求消息， 请求 ITF2接 入， 以获取 ITF1希望在 ITF2呈现的节目内容（由 Content id指示 ) , 该请求消息由 ASM向 ITF2转发；
524. ITF2向 IPTV Control返回 200 OK响应消息 , 该响应消息由 ASM向 IPTV Control功能实体转发；
525. ITF2根据 523中 IPTV功能实体发送的请求消息中的相关信 息， 接入 IPTV档案服务器以获取 IPTV内容。 ITF2可向内容服务器或 传输服务器发送播放请求， 例如， RTSP Play请求消息；
526. 内容服务器返回成功响应；
527. ITF1签约的， 由 Content id指示的内容， 被发送给 ITF2终端 进行播放。
可选的， Content id所指示的内容， 可以为 IPTV Control获取该内 容后 , 发送给 ITF2来接收， 也可以由 IPTV Control通知 ITF2获取该内 容所需的接入参数， 由 ITF2接入内容所在的服务器， 由内容服务器向 ITF2提供所述 Content id所指示的内容。
根据本发明的实施例二，可以实现在第二网络电视终端上播放第一网络电 视终端签约的具体业务内容。 例如， 第一网络电视终端为用户 A的手机， 而 第二网络电视终端为用户 B电视机， 实施例一可以实现用户 A通过手机触发 在用户 B的电视机上播放用户 A签约的 IPTV内容。 用户 A可以通过手机将 具体的节目内容的标识， 例如电影的名称以及播放书签发送给网络侧， 网络侧 根据用户 A指示在用户 B的电视机上继续播放用户 A曾观看或签约的电影。
图 3A和 3B所示的 IPTV业务内容收看系统可以用来实现本发明实施例二 的技术方案。 为此， IPTV Control设备 300的接收模块 310还用于从 ASM单 元 100接收来自 ITF1的 Content id。 而发送模块 330具体用于根据获取模块 320获取的 ITF1的业务档案和 ITF2的标识向 ITF2发送 ITF1签约的、 由所述 Content id指示的业务内容。
图 3示出了本发明实施例的 IPTV业务内容收看系统的一种具体实施例。 如图 3C所示， 根据本发明实施例一和实施例二， IPTV Control设备 300可以 进一步包括确定模块 340, 用于确定 ITF1是否为可请求向 ITF2发送 ITF1签 约内容的签约终端；或确定 ITF2是否为合法的业务内容接收终端；或确定 ITF2 是否为可播放非 ITF2签约业务内容的签约终端； 或确定 ITF2是否具有显示 ITF1签约内容的能力。在这种情况下，发送模块 330具体用于当确定模块 340 确定 ITF1为可请求向 ITF2发送 ITF1签约内容的签约终端；或确定 ITF2为合 法的业务内容接收终端；或确定 ITF2为可播放非 ITF2签约业务内容的签约终 端； 或确定所述 ITF2具有显示 ITF1签约内容的能力时， 根据 ITF1的 IPTV 业务档案和 ITF2的标识向 ITF1发送 ITF1签约的业务内容。 实施例三
图 6是根据本发明的方法实施例三的流程图，而图 7是根据本发明方法实 施例三的一种可能的实现方式的时序图。 实施例三可以实现 ITF2 本地获取 ITF1用户设置的 IPTV 业务档案信息， 并保存在本地， 由 ITF2在本地执行操 作， 获取并播放业务内容， 更新维护 ITF1的 IPTV 业务档案。以下结合图 6和 图 7并同时参照图 1至 3具体说明本发明实施例三的方法。
如图 6所述， 实施例三的方法包括： 在 S610, 网络侧接收请求在第二网 络电视终端 ITF2上播放第一网络电视终端 ITF1签约业务内容的请求消息；在 S620, 根据所述请求消息获取获取 ITF1的 IPTV业务档案和第二网络电视终 端 ITF2的标识；在 S630,接收 ITF2根据 IPTV业务档案发送的更新请求消息， 根据所述更新消息更新 ITF1的 IPTV业务档案信息。
其中 S610和 S620基本上类似于实施例一的方法中的 S110和 S120,因此 不再重复描述。
下面结合图 6和图 7 , 具体描述 S630的可能的具体实现方式。
S630可以包括：
716. IPTV Control功能实体向 IPTV 业务档案服务器发送获取 ITFl 的 IPTV 业务档案的请求信息， 该请求信息中携带 ITF1 用户的标识信 息；
717. IPTV 业务档案服务器向 IPTV Control功能实体返回 ITFl相关 的 IPTV 业务档案信息； 718.根据优选是实施例， IPTV Control功能实体进一步完成判断过 程， 该判断过程可以包括： 判断 ITF2是否为合法的业务内容接收终端， ITF2是否设置播放非 ITF2签约相关内容的偏好， ITF2是否有能力显示 IIF1签约的内容等；
719.如果判断结果为可以向 ITF2发送内容或网络侧功能实体可将 内容转化为 ITF2能力可呈现的内容， 则 IPTV Control向 ASM返回成功 响应消息；如果不可以向 ITF2发送内容，则向 ASM返回失败响应消息； 720. ASM向 ITF1转发成功或失败响应； 如果返回失败， 则终止业 务流程， 以下过程为成功响应的后续流程的举例：
721. ITF2向 IG发送 HTTP Pending消息， 当 IG需要向 ITF2发送 消息时 , 可在此 HTTP Pending消息的响应消息中携带，
722. IPTV Control向 ITF2发送 SIP INFO消息， 该 SIP INFO消息 携带 ITF1相关的 IPTV 业务档案标识信息， ASM转发此消息给 IG;
723. 在本发明的一个实施例中， IG向 ITF2通过 HTTP 200 OK消 息转发 722 SIP INFO消息。此 HTTP 200 OK消息为 721中 HTTP Pending 消息的响应消息。 ITF2可以从 IPTV Control获取 ITF1的 IPTV 业务档 案信息并携带在此消息中；
724.如果可以获取， ITF2将获取的 ITF1的 IPTV业务档案信息存储 在默认的存储区， 存储的 ITF1相关的 IPTV业务档案， 将用于在 ITF2 上呈现 ITF1签约的内容；
725. ITF2向 IG通过 HTTP Pending消息携带成功响应消息；
726. IG 向 ASM返回成功响应； ASM转发此响应消息给 IPTV Control功能实体。
727.内容服务器向 ITF2发送 ITF1签约的业务内容；
728.当业务结束时， 如果需要对 ITF1的 IPTV业务档案进行更新， 则 ITF2将发送更新请求，该请求消息中携带更新的 IPTV业务档案信息， 通过 ITF2更新 ITF1的相应 IPTV 业务档案信息。 网络侧接收到此信息 后， 将根据 ITF1标识信息， 进行更新。
729.根据本发明的一个实施例， ITF2删除其存储在本地的 ITF1的 IPTV 业务档案信息。 通过本发明的实施例三， ITF2可以获取 ITF1的 IPTV业务档案并存储在 本地。 ITF2可以根据获取的 ITF1的 IPTV业务档案播放 ITF1签约的业务内容， 并且在播放完成后， 可以更新存储的 ITF1 的 IPTV业务档案并且通知网络侧 更新存储在业务档案服务器上的 ITF1 的 IPTV业务档案。 这样设计的优势在 于， 例如， 用于在电视机（作为第二终端 ITF2 )上播放手机（作为第一终端 ITF1 )签约的电影之后， 可以在服务器上保存电视机上播放的电影的名称和播 放时间 （作为业务档案信息）， 以便以后在手机或者其他终端 （例如， 另一台 电视机）上接着播放没有播放完的电影。
图 8示出了用来实现本发明实施例三的 IPTV业务内容收看系统的框图。 图 8所示系统是对图 3A和 3B所示的 IPTV业务内容收看系统作出的改进，可 以用来实现本发明实施例三的技术方案。
如图 8所示， IPTV Control设备 300的接收模块 310还用于接收来自 ITF2 的业务档案更新请求， 该请求消息中携带更新 ITF1签约的 IPTV业务档案信 息；发送模块 330用于向 IPTV业务档案服务器 200发送该业务档案更新请求。 IPTV业务档案服务器 200则用于在收到发送模块 330发送的业务档案更新请 求之后， 更新 ITF1签约的 IPTV业务档案信息。 实施例四
图 9是根据本发明的方法实施例四的流程图， 而图 10是根据本发明方法 实施例四的一种可能的实现方式的时序图。 实施例四是对实施例三的改进， 改 进之处在于更新 IPTV业务档案的过程。 实施例四的其他部分即 S910至 S920 与实施例三的 S610至 S620基本类似，因此不再进行重复描述。为了简洁起见， 图 10中的时序图与图 7所示时序图相同的部分也进行了省略。
以下结合图 9和图 10,具体描述实施例四的 S930,即接收 ITF2根据 IPTV 业务档案发送的更新消息， 根据所述更新消息更新 ITF1的 IPTV业务档案。
S930可以包括：
1001. ITF2 对 ITF1 的 IPTV 业务档案进行变更操作， 例如保存新的 bookmark信息、 选择订阅新的个性化频道、 新的节目等变更操作。
1002. ITF2 向 IPTV Control发送携带 IPTV 业务档案变更的信息的消息， 该消息可以携带 ITF1用户标识， 如果网络侧已经进行业务绑定， 则不需要携 带 ITF1用户标识。 即当 ITF2对接收的 IPTV业务或 IPTV内容有任何需要更 新 IPTV业务档案的操作时， 发送此消息；
1003. IPTV Control功能实体接收到此请求信息后， 确定此更新操作为对 ITF1的业务档案更新的操作，此确定过程可根据消息中携带的 ITF1标识、 ITF2 标识、 之前会话标识等信息进行确定。 IPTV Control根据判断， 不是将变更的 操作存储到 ITF2的业务档案中， 而是将变更的操作存储到 ITF1用户的 IPTV 业务档案中。 例如， 将通过 ITF2对节目设定的 bookmark, 保存到 ITF1用户 的 IPTV业务档案中；
1004. IPTV Control功能实体将向 IPTV 业务档案服务器发送请求消息， 可携带 ITF1用户标识， 业务档案索引等信息，通知服务器进行存储更新操作。
1005. IPTV 业务档案服务器返回成功响应；
1006. IPTV Control功能实体向 ITF2返回成功响应；
1007.根据本发明的一个实施例， IPTV Control功能实体可在 ITF1的 IPTV 业务档案信息通过 ITF2完成更新后， 通知 ITF1 ; 即 IPTV Control功能实体向 ITF1发送通知消息， 该通知消息中携带 IPTV 业务档案信息变更的信息；
1008. ITF1向 IPTV Control功能实体返回响应消息。
利用本发明的实施例四，通过 ITF2对 ITF1的 IPTV 业务档案信息操作后， 可通过 ITF2对网络侧的 ITF1的 IPTV 业务档案进行更新。
图 8所示的收看系统可以用来实现实施例四的方法。 为此， IPTV Control 设备 300的发送模块 330还用于在 ITF1的 IPTV业务档案更新后， 向 ITF1发 送通知， 通知所述更新操作。
本发明实施例， ITF为用户 IPTV终端设备的实现举例， 具体可以为 OITF 和 IG分离的 2个物理实体， 可以为 OITF和 IG集成的一个物理实体， 还可以 为单独的 OITF终端。 实施例五
图 11是根据本发明的方法实施例五的时序图。 在实施例五的方法中， 在 ITF2终端上输入 ITF1的用户名密码。 通过输入的用户名密码， 来获取鉴权数 据而进一步获取 ITF1的 IPTV业务档案，或通过用户名密码获取 ITF1的 IPTV 业务档案， 由此进一步向 ITF2发送 ITF1用户签约的业务内容。 结合图 11具 体来说， 实施例五具体包括：
1101 : ITF2鉴权使用网络；
1102: 在 ITF2上输入用户密码， 登陆 IPTV网络。 这里提供了在 ITF2上 用户通过用户名和密码方式， 安全访问 ITF1签约相关 IPTV业务档案的功能， 比如通过应用软件来实现， 对发送的信息进行加密， 通过 ITF2的安全加密机 制来实现传递；
1103: ITF2 向 IPTV Control发送根据 ITF 1用户档案播放内容的请求消息。 该请求中携带用户输入的用户名密码信息；
1104: IPTV Control功能实体返回确认响应；
1105: 可选的， IPTV Control功能实体向用户数据库功能实体发送查询请 求， 获取 ITF1的鉴权数据， 用户获取 ITF1用户档案信息。 当然， 如果不需要 通过鉴权数据来获取 ITF1用户档案信息， 则不执行此过程， 而根据携带的用 户名密码进行获取 ITF1用户档案；
1106: IPTV Control向 IPTV Service Profile服务器发起获取 ITF1业务档 案的请求， 并获取 ITF1业务档案；
1107: IPTV Control与内容服务器 CDN协商向 ITF2提供的业务内容；
1108: ITF2与 CDN服务器传递并播放 ITF2请求的内容。
根据本发明实施例， IPTV用户可以利用签约的终端播放其他终端签约的 业务内容， 实现了 IPTV业务内容在终端之间的灵活转移和切换。 此外， IPTV 用户通过不同签约终端播放的业务内容可以移植到其他终端上继续播放。这样 拜托了终端对 IPTV业务内容的限制， 从而大大扩展了 IPTV业务内容的使用 环境。
通过本发明实施例可以实现通过签约， 用户在使用其它终端观看时，仍可 以通过其他外部设备获取 IPTV签约信息相关的业务的功能。 通过本发明实施 例， 用户可以随意享受自己的签约信息， 随处享受签约的业务。 不需要通过任 何会话转移等业务流程来实现， 或每次的操作来实现， 而实现用户在通过外部 设备观看如同在家里一样的用户体验。
