本实施例提供的方法，在服务器端增加用于保存和管理附加信息的功能，并依据主被叫信息和视频媒体信息查询适合的附加信息，再将该附加信息内容以及视频媒体内容发送给主叫终端的两种端口组，进而实现了利用两个端口组通道将两种资源流传输给主叫终端，实现了在视频彩铃播放过程中添加附加业务的功能，满足了用户进一步的体验需求。
另外，服务器将两种资源流同时下发给主叫终端，以使主叫终端同时播放视频和附加信息，本方法适用于时间间隔较短的视频彩铃场景，可用于海量视频播放，提高了视频播放性能和灵活性。
可选的，本实施例提供的方法，所述方法还包括：

本实施例中，主叫终端通过与服务器进行协商，确定了用于接收视频媒体资源和附加信息资源的两组端口，并利用第一组端口接收视频媒体资源，第二组端口接收附加信息资源，实现了双端口双资源流的接收，实现了画中画形式的视频彩铃播放。
此外，在主叫终端接收两种资源流之后，利用主窗口和副窗口同时分别播放视频彩铃和附加信息，时间差较小，秒级，可以适用于时间短、海量的视频彩铃场景。
在一个具体的实施例中，请参考图4，其示出了本申请实施例提供的一种方法的流程图，该方法可应用于图1所示的系统中。
具体地，该方法可以包括如下步骤：

Figure PCTCN2020072492-appb-000001
表1
如表1所示，可选的描述项使用“*”来表示。
通常，一个会话包含多个媒体描述，每个媒体描述都是以“m＝”开头，一直到下一个“m＝”截止，或者到会话描述的最后。其中，
1.<media>指示媒体的类型，目前定义的媒体类型有“audio”、“video”、“application”、“data”和“control”，此外将来还可能会由于新的通信形式，例如telepresence等的出现而拓展出新的媒体类型。
2.<port>指示接受媒体流传输端口，所述传输端口的含义取决于相关的“c＝”行中指定的网络类型，后面的<transport>指示传输协议。例如，对于基于用户数据报协议(User Datagram Protocol，UDP)的端口，端口号范围为[1024-65535]，为了符合RTP传输，一般端口号为偶数，具体可以表示为：
m＝<media><port>/<number of ports><transport><fmt list>
本实施例中，对于第一SDP描述中的视频彩铃媒体资源，传输音频(audio)资源，对应的第一端口号为“8386”。另外，对于IP4，绝大多数媒体流是通过RTP/UDP传送，对于RTP音频、视频资源的RTP媒体流，协议值为“RTP/AVP”，其中，AVP分别对应Audio/Video Proflie。同理地，“m＝video 7398”表示第一SDP描述中还包括传输视频(video)资源，对应的第二端口号为“7398”，用于接收该视频资源。
其中，所述第一端口号“8386”所对应的第一端口和第二端口号“7398”所对应的第二端口可以组成第一组端口，用于接收视频彩铃媒体资源。
同理地，对于第二SDP描述中的附加信息资源，可以指示用于传输另一视频(video) 资源，对应传输的第三端口号为“2265”，用于传输附加信息流，且第三端口号与第一端口号和第二端口号均不同。
可选的，所述第三端口号可以作为传输所述附加信息流的第二组端口，所述第二组端口中还可以包括其它端口，例如第四端口，来传送音频资源等。
本方法中，关于附加信息资源的提供，RBT-AS仅需要在原始视频彩铃媒体资源的过程中，协商增加一个video类型的附加信息流(RTP流)，用于传输附加信息资源，并将该附加信息流协同原来的视频彩铃媒体流通过指定的不同组端口来传输，实现了双端口双资源流的传输，进而满足在视频彩铃媒体播放时增加附加信息的功能，满足用户进一步的体验需求。
可选的，所述SDP消息为SIP UPDATE消息。具体地，RBT-AS将所述第一SDP描述和第二SDP描述通过会话发起协议(Session Initiation Protocol，SIP)UPDATE消息下发给主叫终端。
可选的，RBT-AS将所述SIP消息通过S-CSCF转发给主叫终端。
步骤407：主叫终端接收S-CSCF转发的SDP消息，解析该SDP消息，并向RBT-AS反馈响应消息。
具体地，所述SDP消息中包括所述第一SDP描述和第二SDP描述，其中所述第一SDP描述指示主叫终端利用的第一组端口接收第一实时传输协议(real time protocol，RTP)流，所述第二SDP描述指示主叫终端利用的第二组端口接收第二RTP流，所述第一组端口和第二组端口不同。进一步地，所述第一RTP流为视频彩铃媒体流，包括接收音频资源的第一端口和接收视频资源的第二端口，所述第二RTP流为附加信息流，包括用于接收视频资源的第三端口。
可选的，主叫终端将所述响应消息发送给S-CSCF，再由所述S-CSCF将该响应消息转发给RBT-AS。
步骤408：主叫终端根据所述SDP消息完成视频彩铃媒体资源和附加信息资源的预留，并生成预留确认通知，以及将所述预留确认通知发送给RBT-AS。
步骤409：RBT-AS接收到所述主叫终端的预留确认通知之后，再将所述预留确认通知发送给RBT-MRS。
步骤410：RBT-MRS接收到来自所述RBT-AS的预留确认通知之后，向RBT-AS回复确认消息。可选的，所述确认消息为“200OK”。
步骤411：RBT-AS接收并转发该确认消息给主叫终端。
可选的，RBT-AS将所述确认消息通过S-CSCF转发给主叫终端。
步骤412：RBT-MRS向主叫终端的第一组端口传输视频彩铃媒体流。
步骤413：RBT-MRS向主叫终端的第二组端口传输附加信息流。
其中，所述第一组端口和第二组端口的端口号不同，所述视频彩铃媒体流对应视频彩铃媒体资源的传输，所述传输附加信息流对应附加信息资源的传输，且这两种资源均可以通过数据包的方式发送给主叫终端。
进一步地，RBT-MRS将所述视频彩铃媒体流和所述传输附加信息流同一时刻发送给主叫终端，以使所述主叫终端同时接收到两种RTP流。
需要说明的是，本实施例所述的视频彩铃媒体流也可以是视频彩铃媒体内容，同理地，所述附加信息流可以是附加信息内容，本实施例对此不予限制。
步骤414：主叫终端利用第一组端口接收所述视频彩铃媒体流，同时利用第二组端口接收所述附加信息流，进一步地，主叫终端调用播放器在主窗口播放所述视频彩铃媒体资源所对应的视频彩铃，以及将所述附加信息流通过附加信息控制模块进行处理，所述附加信息控制模块分析所述附加信息流的信息类型，并加载，以及通过副窗口显示该附加信息。
其中，所述第一组端口和所述第二组端口可以为主叫终端的通话应用层的两个端口。
可选的，若主叫终端同时接收到所述视频彩铃媒体流和所述传输附加信息流，则分别利用主窗口和副窗口实现同步播放视频彩铃和附加信息，时间间隔短(时间间隔为毫秒级)，进而可以适合时间短的视频彩铃的场景。
步骤415：主叫终端的用户基于副窗口播放的附加信息进行交互操作，比如，点击副窗口的产品链接获得响应，或者关闭副窗口等交互操作，以及上传交互操作信息。
步骤416：主叫终端向附加信息服务器上报交互操作信息。
例如，所述交互操作信息包括：主叫用户利用副窗口展示的附加信息的时长、或交互(点击或关闭)等信息。进一步地，所述上报交互操作信息可以是通过调用服务器端提供的接口(比如，一般为web restful API)上报，所述上报的交互信息可以记录在附加信息服务器上或者其他的类似服务器上，以便附加信息服务器记录主叫终端交互操作信息，其中，该记录的结果可以被用于后续的附加信息投放和使用。
可选的，主叫终端还可以将主窗口展示的视频彩铃与用户交互的信息上报给RBT-AS或RBT-MRS。
本实施例提供的方法，在原彩铃媒体系统的基础上增加附加信息服务器，用于保存和管理附加信息，并根据RBT-MRS的请求向主叫终端提供适合的附加信息，从而实现了服务器在向主叫终端提供视频彩铃业务的同时，还提供附加信息业务，本方法满足了用户进一步的体验需求。
另外，提供附加信息的附加信息服务器是根据请求消息中的彩铃媒体标识、或主叫标识、或被叫标识查找的适合于主被叫用户的附加信息，是动态分配的过程，即可根据媒体资源的不同和主被叫标识不同而动态变化，进一步地增加了提供附加信息业务的灵活性，从而增加了服务质量。
进一步地，如图5所示，主叫终端中包括操作系统(Operating System，OS)，以及在该OS下运行的通话应用500，该通话应用500包括：通话处理模块501，附加信息控制模块502和用户界面(User Interface，UI)显示模块503。其中，通话处理模块501用于实现主叫终端的通话功能，例如，进行拨号，呼叫被叫终端，与各种服务器之间进行消息传输等。
附加信息控制模快502，用于解析SDP消息，并根据RTP流的类型，将附加信息以合适的形式显示在副窗口上，比如根据附加信息的视频的长宽比、图片的长宽、文字的多少调整副窗口的长宽。
