为了使本发明的目的、 技术方案和优点更清楚， 下面结合附图和具 体实施方式对本发明作进一步描述。 本发明的核心思想是： 在通信终端上增加对流媒体播放、 控制协议 进行处理的流媒体控制单元， 并对通信终端所使用的通信信令进行扩展 以使其支持流媒体业务， 从而在通信终端上实现流媒体业务。
通过本发明， 在不改变用户使用习惯的基础上， 为用户提供方便的 基于通信终端的流媒体业务， 使 IP机顶盒的功能在通信终端上得以实 现，从而实现 IP数字机顶盒与通信终端的功能统一，并在不增加许多成 本的前提下， 使用户能够方便灵活地使用具有流媒体功能的通信终端。
图 2是根据本发明的具有流媒体功能的通信终端的结构示意图。 如 图 2所示，本发明的通信终端主要包括流媒体控制单元、呼叫控制单元、 视频处理单元、 音频处理单元和通信处理单元。
其中的呼叫控制单元、 视频处理单元、 音频处理单元和通信处理单 元分别具有现有技术的通信终端中各对应单元所具有的基本功能。 这几 个单元配合工作可实现现有技术通信终端具有的视音频通信的功能。
其中的流媒体控制单元可对与流媒体播放、 控制相关的协议进行处 理， 并控制流媒体业务的相关流程，其与呼叫控制单元、视频处理单元、 音频处理单元和通信处理单元分别连接， 互相配合工作实现现有技术的 通信终端所不具有的流媒体功能。
本发明的通信终端在实现视音频通信的过程中， 首先与网络侧的注 册服务器交互， 完成通信终端的注册过程； 在呼叫另一通信终端时， 也 通过与网络侧注册 务器的交互完成呼叫认证和地址解析等功能， 然后 建立与另一通信终端的连接和呼叫。
本发明的通信终端在实现流媒体业务时， 可通过对通信终端与网络 侧注册服务器之间交互的通信信令进行扩展， 使扩展后的通信信令支持 与流媒体相关的信息的传递， 从而实现通信终端对流媒体业务的支持； 也可以增加新的流媒体业务专用通信信令实现通信终端对流媒体业务 的支持。
由此可见， 本发明的通信终端和现有技术的通信终端相比， 由于增 加了流媒体控制单元， 并对原有通信信令进行扩展或增加新的与流媒体 业务相关的通信信令， 在实现视音频通信的同时， 实现流媒体业务。
下面结合四个实现流媒体业务的具体实施例对本发明的实现流媒体 业务的通信终端、 ***和方法进行详细介绍。
第一实施例：
在本实施例中，通信终端在注册过程中，获取流媒体业务相关信息。 这样， 可通过该节目单为通信终端用户提供流媒体点播或直播等业务， 或者在通信终端空闲时， 向通信终端用户自动播放流媒体广告。

第三步， 通信终端接收到呼叫确认消息后， 如果发现呼叫确认消息 中包含流媒体业务相关信息， 且该流媒体业务相关信息为单一流媒体节 目的 U L链接， 则向流媒体服务器请求播放该流媒体节目的 URL链接 所指向的流媒体数据。
第四步， 流媒体服务器向通信终端播放流媒体节目， 即向通信终端 返回其所请求的流媒体节目所对应的流媒体数据。
图 4b是第二实施例的通信信令交互示意图。 如图 4b所示， 呼叫控 制单元通过通信处理单元和通信网络向注册服务器发送呼叫请求； 注册 服务器在对通信终端的认证通过后， 解析被叫号码， 并将包含被叫号码 所对应的流媒体业务相关信息的呼叫确认消息反馈给通信处理单元； 通 信处理单元将呼叫确认消息转发给呼叫控制单元； 呼叫控制单元得到流 媒体业务相关信息， 例如单一流媒体节目的 U L链接后， 将其转发给 流媒体控制单元； 流媒体控制单元通过通信处理单元向流媒体服务器发 起对该单一流媒体节目的连接请求； 流媒体服务器通过通信网絡将连接 请求的结果反馈给通信处理单元； 通信处理单元将该连接请求结果转发 给流媒体控制单元进行处理； 在连接成功后， 流媒体控制单元指示音频 处理单元和视频处理单元准备接收数据， 然后开始流媒体播放。
