实体的网络资源， 来播放视频流媒体或者上传视频文件。 移动终端通过与附近计算实体的协商， 获得其网络资源使用的许可， 发 送具体的流媒体链接地址和终端支持能力到计算实体请求其代为链接， 计算 实体链接成功后将获得的流媒体视频数据传输给移动终端进行播放， 最终终 端能够借助计算实体的网络资源， 进行流畅地播放视频流媒体。 如图 1所示，本发明实施例的用于实现移动终端多媒体远程交互的系统， 包括移动终端和计算实体， 其中： 移动终端设置为： 与计算实体建立无线连接， 经计算实体与多媒体服务 器进行多媒体交互； 计算实体设置为： 与移动终端建立无线连接， 在移动终端与多媒体服务 器之间转发交互信令及多媒体数据。 所述的多媒体数据交互包括移动终端经计算实体向多媒体服务器请求流 媒体播放， 和 /或移动终端经计算实体向多媒体服务器发送本地多媒体文件。 所述无线连接是近距离无线连接， 无线连接方式包括： 蓝牙、 WIFI、 ZigBee 等方式。 所述计算实体包括台式电脑、 笔记本电脑、 具备个人电脑 ( Personal Computer, PC )功能的移动终端。 移动终端与计算实体建立连接时， 首先， 移动终端选择近距离无线连接 方式（比如蓝牙、 WIFI等）， 利用近距离无线连接方式搜索附近区域是否有 可用的计算实体， 即搜索与移动终端釆用相同近距离无线连接方式且提供接 入服务的计算实体； 计算实体开启近距离无线连接（比如蓝牙、 WIFI等） ， 用于向移动终端提供接入服务； 然后， 移动终端搜索到计算实体， 并获取后 者的网络资源性能， 向计算实体发送接入请求和远程网络资源借用或租用的 请求； 之后， 开启了近距离无线连接的计算实体收到接入请求后， 根据自身 运行情况， 决定是否借用或出租其网络资源能力： 如果该计算实体是商业计算实体提供者， 则告知移动终端租用费用； 如果该计算实体是自由计算实体提供者， 则向移动终端索取密码； 最后， 移动终端接受费用并向商业计算实体提供者确认后， 或者向自由
计算实体提供者提供密码后， 移动终端以远程登陆的方式接入计算实体， 双 方近距离无线连接建立。 在移动终端与计算实体建立连接后， 移动终端一方面可以向计算实体发 送请求播放的媒体链接， 计算实体向媒体链接对应的多媒体服务器请求流媒 体数据， 将接收的流媒体数据转发给移动终端， 移动终端对接收的流媒体数 据进行播放； 另一方面， 移动终端经计算实体向多媒体服务器请求上传媒体文件， 协 商后， 可以选择本地多媒体文件发送给计算实体， 计算实体将本地多媒体文 件转发至多媒体服务器， 完成上传。 本发明实施例的用于实现移动终端多媒体远程交互的方法包括： 移动终端与计算实体建立无线连接， 经计算实体与多媒体服务器进行多 媒体交互， 所述多媒体交互包括： 交互信令及多媒体数据交互。 所述的多媒体数据交互包括： 移动终端经计算实体向多媒体服务器请求 流媒体播放， 和 /或移动终端经计算实体向多媒体服务器发送本地媒体文件。 在移动终端经计算实体向多媒体服务器请求播放流媒体时， 所述的多媒 体服务器是流媒体服务器。

计算实体利用无线模块许可移动终端建立无线通信连接后， 计算实体通 过无线模块接收移动终端发送的网络命令并利用网络模块完成其所要实现的
与多媒体服务器之间的网络连接功能， 网络模块接收多媒体服务器经数据传 输模块传送过来的流媒体数据和控制命令，并利用无线模块回送给移动终端。 其中， 移动终端的具体描述可参见优选实施例 3。 如图 3所示， 本发明实施例的移动终端的流媒体远程播放方法的具体实 施步骤包括： 步骤 301 , 移动终端与邻近的计算实体建立无线连接； 其中， 所述无线连接是近距离无线连接， 近距离无线连接方式包括： 蓝 牙、 WIFI、 ZigBee等方式。 所述计算实体包括台式电脑、 笔记本电脑、 以及 具备 PC功能的移动终端； 建立连接时， 首先， 移动终端选择近距离无线连接方式 （比如蓝牙或
