( 1 )业务控制装置 22可以根据用户的签约信息确定可以提供的交互信息参数， 例如： 用户的 签约信息为只接收投票信息、不接收购物信息， 业务控制装置 22可以根据用户的签约信息向用户提 供合适的交互信息参数；  (1) The service control device 22 can determine the interaction information parameters that can be provided according to the subscription information of the user. For example, the subscription information of the user is to receive only the voting information, and the shopping information is not received, and the service control device 22 can provide the user with the subscription information according to the user. Provide appropriate interactive information parameters;
( 2 )业务控制装置 22可以根据用户终端的能力信息确定可以提供的交互信息参数。  (2) The service control device 22 can determine the interactive information parameters that can be provided according to the capability information of the user terminal.
另外， 业务控制装置 22可以动态地从交互信息提供装置 23获取交互信息参数， 并确定可以提 供给交互信息接收装置 21的交互信息参数。  Further, the service control device 22 can dynamically acquire the interactive information parameters from the interactive information providing device 23, and determine the interactive information parameters that can be supplied to the interactive information receiving device 21.
而且， 基于交互信息接收装置 21通常在用户终端实现， 所以根据用户终端的能力信息， 业务控 制装置 22确定可以提供给交互信息接收装置 21的交互信息参数， 也可以理解为， 根据交互信息接 收装置 21的能力信息， 业务控制装置 22确定可以提供给交互信息接收装置 21的交互信息参数。  Moreover, the interaction information receiving device 21 is usually implemented in the user terminal, so according to the capability information of the user terminal, the service control device 22 determines the interaction information parameter that can be provided to the interaction information receiving device 21, and can also be understood as the interaction information receiving device. The capability information of 21, the service control device 22 determines the interactive information parameters that can be provided to the interactive information receiving device 21.
步骤 S303, 业务控制装置 22向交互信息接收装置 21发送可用的交互信息参数。  Step S303, the service control device 22 transmits the available interactive information parameters to the interactive information receiving device 21.
在发送可用的交互信息参数时， 业务控制装置 22可以通过 SIP响应消息携带交互信息参数。具 体可以为： SIP 响应消息可以通过消息实体类型 （Content-Type ) 标识交互信息参数， 并通过 SIP 消息体携带交互信息参数。  When transmitting the available interactive information parameters, the service control device 22 may carry the interactive information parameters through the SIP response message. Specifically, the SIP response message may identify the interaction information parameter by using a message entity type (Content-Type), and carry the interaction information parameter through the SIP message body.
例如： 可以使用如下 SIP消息体类型： application/iptv-interactive-info-para+xml For example: The following SIP message body types can be used: Application/iptv-interactive-info-para+xml
交互信息参数可以通过 XML (extensible Marked Language, 可扩展标记语言） 定义， 例如使 用如下 XML模板：  The interactive information parameters can be defined by XML (extensible Marked Language), for example using the following XML template:
<?xml version=〃L 0〃 encoding=〃UTF- 8〃?〉  <?xml version=〃L 0〃 encoding=〃UTF- 8〃?>

或者 SIP响应消息可以通过 SDP属性行 （attributes line ) 携带交互信息参数， 这里属性行可 以是会话级 （session-level ) 或者媒体级 （media-level ), 例如新定义属性行：  Or the SIP response message can carry the interactive information parameter through the SDP attribute line, where the attribute line can be a session-level or a media-level, for example, a newly defined attribute line:
a=  a=
interactive— info ara : < interact ive— info— para— id〉< interactive— info roviderXtemplate—1 istXreference_id> Interactive— info ara : < interact ive— info— para— id>< interactive— info roviderXtemplate—1 istXreference_id>

<content> ：： =<content_type><content_location>  <content> :: =<content_type><content_location>
当通过媒体级 （media-level ) 属性行携带交互信息参数时， 业务控制装置 22具体可以采用以 下一种或两种方式下发交互信息参数：  When the interaction information parameter is carried by the media-level attribute line, the service control device 22 may specifically send the interaction information parameter in one or two ways:
( 1 ) 业务控制装置 22 可以通过 SDP ( Session Description Protocol , 会话描述协议） offer/answer (提供 /应答)机制控制完成基本业务媒体传送通道协商时，将交互信息参数作为基本业 务媒体传送通道的属性行完成交互信息接收装置 21与交互信息提供装置 23之间的交互信息参数协 商， 并将合适的交互信息参数传送给交互信息接收装置 21 ;  (1) The service control device 22 can control the basic service media transmission channel negotiation through the SDP (Session Description Protocol) offer/answer mechanism, and use the interaction information parameter as the attribute of the basic service media transmission channel. The line completes the interaction information parameter negotiation between the interaction information receiving device 21 and the interaction information providing device 23, and transmits the appropriate interaction information parameter to the interaction information receiving device 21;
( 2 )业务控制装置 22可以控制完成交互信息接收装置 21与交互信息提供装置 23之间交互信 息传送通道的建立， 该交互信息传送通道用于传送交互信息， 将交互信息参数作为交互信息传送通 道的属性行完成交互信息参数协商， 将合适的交互信息参数送给交互信息接收装置 21。  (2) The service control device 22 can control the establishment of the interaction information transmission channel between the interaction information receiving device 21 and the interaction information providing device 23, the interaction information transmission channel is used for transmitting the interaction information, and the interaction information parameter is used as the interaction information transmission channel. The attribute line completes the negotiation of the interactive information parameters, and sends the appropriate interactive information parameters to the interactive information receiving device 21.
其中， 交互信息传送通道可以通过 SDP offer/answer机制协商建立， 通过媒体描述行 (media descriptions line ) 携带交互信息传送通道媒体参数， 其中媒体属性 (media attributes ) 可以为 application, audio, text 等； 还可以通过自定义媒体格式描述 （fmt ) 确定传送通道属性为交互 信息传送通道；例如交互信息媒体属性为 "application",通过 tcp( transmission control protocol , 传输控制协议） 传输， 并且新定义 fmt为 " iptv-interactive-info", 因此媒体描述行可以为： m = application 10234 tcp iptv-interactive-info The interactive information transmission channel may be negotiated and established through the SDP offer/answer mechanism, and the media descriptions line carries the media parameters of the interactive information transmission channel, where the media attributes may be Application, audio, text, etc.; can also determine the transfer channel attribute as the interactive information transfer channel through the custom media format description (fmt); for example, the interactive information media attribute is "application", transmitted by tcp (transmission control protocol) , and the new definition fmt is "iptv-interactive-info", so the media description line can be: m = application 10234 tcp iptv-interactive-info
协商建立交互信息传送通道时， 业务控制装置 22可以作为代理服务器（Proxy), 交互信息接收 装置 21与交互信息提供装置 23之间直接协商建立交互信息传送通道； 或者，  When the interaction information transmission channel is negotiated, the service control device 22 can act as a proxy server (Proxy), and the interaction information receiving device 21 and the interaction information providing device 23 directly negotiate to establish an interaction information transmission channel; or

The interactive information receiving device 21 and the interactive information providing device 23 respectively negotiate with the service control device 22 to establish an interactive information transmission channel. The interactive information providing device 23 and the service control device 22 can negotiate through SIP or non-SIP protocols.
建立交互信息传送通道时的协商可以进行多轮。  Negotiation when establishing an interactive information transmission channel can be performed in multiple rounds.

步骤 S401， SCF从 Voting-F获取投票信息的交互信息参数。  Step S401, the SCF acquires the interaction information parameter of the voting information from the Voting-F.
在本实施例中， SCF可以使用 SIP协议， 例如 SIP MESSAGE等， 或者非 SIP协议， 例如 HTTP协 议等获取投票信息的交互信息参数。  In this embodiment, the SCF may use a SIP protocol, such as SIP MESSAGE, or a non-SIP protocol, such as an HTTP protocol, to obtain interactive information parameters of the voting information.
步骤 S402， IPTV用户通过 UE发起 BC业务请求， BC业务请求中携带频道标识 Channel-1， IMS 核心将 BC业务请求中继到 SCF。  Step S402: The IPTV user initiates a BC service request by using the UE, and the BC service request carries the channel identifier Channel-1, and the IMS core relays the BC service request to the SCF.

In this embodiment, the SCF determines that Program-A in Channel-1 can provide voting information and obtain corresponding interactive information parameters.
步骤 S404， SCF通过 SIP 200 0K响应消息体携带投票信息的交互信息参数， 将该交互信息参数 传送给 UE。 本实施例中 SIP 200 0K响应消息同时携带 BC业务媒体参数以及交互信息参数， 可以通 过如下方式携带：  Step S404: The SCF carries the interaction information parameter of the voting information by using the SIP 200 0K response message body, and transmits the interaction information parameter to the UE. In this embodiment, the SIP 200 0K response message carries the BC service media parameters and the interaction information parameters, and can be carried in the following manner:

步骤 S406， UE与 Voting-F交互获取交互信息， 并且根据交互信息参数的描述解析并呈现交互 信息。这里 Voting-F可以主动向 UE推送交互信息， 也可以是 UE根据交互信息参数中的描述主动向 Voting-F请求交互信息。  Step S406: The UE interacts with the Voting-F to obtain interaction information, and parses and presents the interaction information according to the description of the interaction information parameter. Here, the Voting-F may actively push the interaction information to the UE, or the UE may actively request the interaction information from the Voting-F according to the description in the interaction information parameter.
本实施例中步骤 S401所示 SCF从 Voting-F获取投票信息的交互信息参数， 实际上 SCF也可以 通过后台部署等方式从其它可以提供交互信息参数的功能实体处获取。  In the embodiment, the SCF obtains the interaction information parameter of the voting information from the Voting-F in the step S401. In fact, the SCF can also be obtained from other functional entities that can provide the interaction information parameter by way of background deployment.
本实施例中如步骤 S401所示 SCF预先获取交互信息参数，实际 SCF也可以是在基本业务触发过 程中动态获取交互信息参数。 本实施例中 SCF还可以获取用户的状态信息、 用户的签约信息及用户终端的能力等信息， 基于 这些信息为用户选择合适的交互信息参数并下发， 例如当前用户 UE只支持 XHTML格式时， SCF可以 只向 UE传送 XHTML格式的交互信息参数。 如图 5所示， 为本发明交互信息的传送方法实施例三的流程图， 实施例三通过媒体属性协商交 互信息参数。业务或内容提供商部署投票业务（Voting), 为 Channel-1播放的 Program-A附加投票 信息， 并生成投票信息的交互信息参数。 交互信息参数描述了投票信息可以使用的模板格式、 关联 的频道及节目等信息。 In this embodiment, as shown in step S401, the SCF obtains the interaction information parameter in advance, and the actual SCF may also dynamically acquire the interaction information parameter in the basic service triggering process. In this embodiment, the SCF can also obtain information such as the user's status information, the user's subscription information, and the capabilities of the user terminal. Based on the information, the SCF selects the appropriate interaction information and sends the information to the user. For example, when the current user UE only supports the XHTML format, The SCF may only transmit the interactive information parameters in the XHTML format to the UE. As shown in FIG. 5, it is a flowchart of Embodiment 3 of a method for transmitting interaction information according to the present invention. Embodiment 3 negotiates an interaction information parameter by using a media attribute. The service or content provider deploys a voting service (Voting), attaches voting information to the Program-A played by Channel-1, and generates interactive information parameters of the voting information. The interactive information parameter describes the template format, associated channels, and programs that the voting information can use.

The additional media attribute line (a-line) in the description carries the interactive information parameters of the channel or program. In the present embodiment, the service control device 22 determines that the Program-A in Channel-1 can provide the voting information, and therefore the interactive information parameters for attaching the voting information through the media attribute line are as follows:
a=interactive_info_para : channel- 1- voting template— list： voting- xhtml application/x-gzip serie- a- voting, gz content— list : application/xhtml+xml voting, html, text/css voting-style, ess, image/gif voting, gif reference— id : Program- a a=interactive_info_para : channel- 1- voting template— list: voting- xhtml application/x-gzip serie- a- voting, gz content— list : application/xhtml+xml voting, html, text/css voting-style, ess, Image/gif voting, gif reference— id : Program- a

Subsequent local interactive applications can parse and present the received voting information to the user based on the template.
步骤 S506， UE与 Voting-F交互获取交互信息， 并且根据交互信息参数的描述解析并呈现交互 信息。这里 Voting-F可以主动向 UE推送交互信息， 也可以是 UE根据交互信息参数中的描述主动向 Voting-F请求交互信息。  Step S506: The UE interacts with the Voting-F to obtain interaction information, and parses and presents the interaction information according to the description of the interaction information parameter. Here, the Voting-F may actively push the interaction information to the UE, or the UE may actively request the interaction information from the Voting-F according to the description in the interaction information parameter.
本实施例中步骤 S501所示 SCF从 Voting-F获取投票信息的交互信息参数， 实际上 SCF也可以 通过后台部署等方式从其它可以提供交互信息参数的功能实体处获取。  In the embodiment, the SCF obtains the interaction information parameter of the voting information from the Voting-F in the step S501. In fact, the SCF can also be obtained from other functional entities that can provide the interaction information parameter by way of background deployment.
本实施例中如步骤 S501所示 SCF预先获取交互信息参数，实际 SCF也可以是在基本业务触发过 程中动态获取交互信息参数。  In this embodiment, as shown in step S501, the SCF obtains the interaction information parameter in advance, and the actual SCF may also dynamically acquire the interaction information parameter during the basic service triggering process.
本实施例中 SCF还可以获取用户的状态信息、 用户的签约信息及用户终端的能力等信息， 基于 这些信息为用户选择合适的交互信息参数并下发， 例如当前用户 UE只支持 xhtml格式， 因此 SCF可 以只向 UE传送 xhtml格式的交互信息参数。 如图 6所示， 为本发明交互信息的传送方法实施例四的流程图， 实施例四中 UE发起交互信息通 道协商传送交互信息。 业务或内容提供商部署投票业务 （Voting), 为 Channel- 1播放的 Program-A 附加投票信息， 并生成投票信息的交互信息参数。 交互信息参数描述了投票信息可以使用的模板格 式、 关联的频道及节目等信息。  In this embodiment, the SCF can also obtain the information of the user, the subscription information of the user, and the capability of the user terminal, and select the appropriate interaction information parameter for the user based on the information, for example, the current user UE only supports the xhtml format. The SCF may only transmit the interactive information parameters in the xhtml format to the UE. As shown in FIG. 6, FIG. 6 is a flowchart of Embodiment 4 of a method for transmitting interaction information according to the present invention. In Embodiment 4, the UE initiates an interactive information channel to negotiate and transmit interaction information. The business or content provider deploys a voting service (Voting), attaches voting information for Program-A played by Channel-1, and generates interactive information parameters of the voting information. The interactive information parameter describes the template format, associated channels, and programs that the voting information can use.
