Description

一种文件下载的方法及装置
技术领域
本发明涉及移动多媒体广播技术领域， 尤其涉及一种文件下载的方法及 装置。
背景技术
移动多媒体广播业务（又叫手机电视）有多种实现技术， 有基于移动通 信网络的多媒体广播多播技术 （Multimedia Broadcast Multicast Service , MBMS ) 、 广播和多播技术（Broadcast and Multicast Service, BCMCS ) 、 流 媒体技术， 也有基于广播网 （地面数字广播、 卫星数字广播等） 的技术。 基 于广播网的移动多媒体业务具有频谱利用率高、 容量大、 建设成本相对较低、 受众广等优势， 已得到广泛应用。
移动多媒体广播主要有两大类业务， 音视频广播业务和数据广播业务。 数据广播业务又可细分为文件下载类业务（如手机报、 影视片断、 幽默短片、 新闻 /体育节目等）和实时数据流业务（如股票和交通导航） 。
用户在使用电视以及实时数据流业务时，需要先通过节目指南进行导航， 选择需要观看的节目， 客户端调用相应的播放器进行相应的业务服务， 为用 户提供业务。 但是， 与电视播放以及实时数据流业务不同， 下载类业务不需 要用户的实时关注， 如果按照上述模式， 会对用户的业务使用带来很大的不 便， 例如：
>由于用户无法记住多媒体广播什么时间播发什么文件， 因此， 需要不 时的去查看文件播发节目表， 根据自己订购的文件或栏目的下发时间， 手动 切换到相应的频道进行下载， 如果文件是晚间下发， 用户必须晚上操作客户 端进行下载， 如果用户订购了多个不同时间下发的多个文件， 还必须多次手 动操作。
>进入文件下载状态后， 用户必须等待文件下载完成后， 再手动退出相 应的频道， 这对用户的使用造成了很大的限制。 发明内容
本发明要解决的技术问题是提供一种文件下载方法及装置， 解决移动多 媒体广播业务中下载文件时需要人工干预的问题， 实现无需人工干预即可在 文件播发时间进行文件的下载。
为解决上述技术问题， 本发明提供一种文件下载的方法， 应用于移动多 媒体广播系统中， 包括： 客户端向用户展示播发信息， 供用户选择待下载文件；
客户端接收用户对待下载文件的选择， 读取用户选择的待下载文件的播 发信息， 并在待下载文件的播发信息中包含的播发开始时间到达时， 将待下 载文件下载到本地。
客户端向用户展示播发信息的步骤包括：
客户端从所接收到的电子节目指南中提取出时间编排表， 并从该时间编 排表中提取出播发信息， 生成定制界面， 在该定制界面中将所提取出的播发 信息展示给用户。
客户端读取用户选择的待下载文件的播发信息的步骤包括： 用户在定制界面上根据所展示的播发信息选择待下载文件后， 客户端从 所提取出的播发信息中， 读取出用户所选择的待下载文件的播发信息， 并保 存到文件下载设置表中。
客户端在播发开始时间到达时， 将待下载文件下载到本地的步骤包括： 客户端根据文件下载设置表中保存的每个待下载文件的播发信息中包含 的播发开始时间， 相应地配置并启动一定时器， 定时器的定时结束时间为对 应的待下载文件的播发开始时间；
在定时器定时结束时， 客户端调用文件下载单元， 并切换到相应待下载 文件的播发信道上， 将该待下载文件下载到本地。
客户端在将用户所选择的待下载文件的播发信息保存到文件下载设置表 中之前， 上述方法还包括：
客户端判断该用户是否已订购所选择的待下载文件， 如果是， 则执行将 该用户所选择的待下载文件的播发信息保存到文件下载设置表中的步骤； 如 果否， 提示用户所选择的待下载文件未订购。
客户端判断该用户是否已订购所选择的待下载文件的步骤包括： 客户端 通过查询认证授权卡或客户识别模块卡上的移动多媒体广播权限信息判断用 户是否已订购所选择的待下载文件。
客户端在播发开始时间， 将待下载文件下载到本地的步骤包括： 客户端每隔一个时间周期扫描文件下载设置表， 当到达待下载文件的播 发开始时间时， 调用文件下载单元， 并切换到相应待下载文件的播发信道上， 将该待下载文件下载到本地。
为解决上述技术问题， 本发明还提供一种文件下载的装置， 应用于移动 多媒体广播系统中， 包括： 控制单元、 播发信息展示单元、 文件下载单元、 用户接口单元和存储单元， 其中：
播发信息展示单元设置为： 保存播发信息， 并向用户展示该播发信息， 供用户选择待下载文件；
用户接口单元， 与控制单元连接， 其设置为： 接收用户对待下载文件的 选择， 通知控制单元用户选择的待下载文件；
控制单元， 与用户接口单元、 播发信息展示单元和文件下载单元连接， 其设置为： 在获知用户选择的待下载文件后， 从播发信息展示单元读取待下 载文件的播发信息，在待下载文件的播发信息中包含的播发开始时间到达时， 调用文件下载单元；
文件下载单元， 与控制单元和存储单元连接， 其设置为： 在控制单元的 调用下， 将待下载文件下载到存储单元。
播发信息展示单元是设置为以如下方式向用户展示播发信息：
从所接收到的电子节目指南中提取出时间编排表， 并从该时间编排表中 提取出播发信息， 生成定制界面， 在该定制界面中将所提取出的播发信息展 示给用户。
控制单元是设置为以如下方式在待下载文件的播发信息中包含的播发开 始时间到达时， 调用文件下载单元： 从播发信息展示单元读取出待下载文件的播发信息后， 将该播发信息保 存到文件下载设置表中， 并根据该文件下载设置表中保存的每个待下载文件 的播发信息中包含的播发开始时间， 相应地配置并启动一定时器， 定时器的 定时结束时间为对应的待下载文件的播发开始时间； 在定时器定时结束时， 调用文件下载单元。
综上所述， 本发明基于时间编排表为用户提供选择， 并在用户所选文件 的播发时间进行文件下载， 使得用户在使用移动多媒体广播业务时， 不需要 人工干预即可完成文件下载， 省去了用户的大量手动操作， 改善了用户的业 务体验， 本发明的方法适用于各种移动多媒体广播系统， 很多移动多媒体广 播系统为了充分利用网络资源， 通常在晚上网络比较空闲的时候播发文件， 用户在订购文件后， 终端可自行下载相应的文件， 无需用户参与， 不会影响 用户的休息。
附图概述
图 1为本发明的文件下载的方法的流程图；
图 2为本发明中釆用的定制界面的示意图；
图 3为本发明中用户在定制界面上选择待下载文件的示意图；
图 4为本发明实施方式的文件下载的装置的架构图。
本发明的较佳实施方式
在移动多媒体广播业务中， ESG (电子业务指南又称： 电子节目指南） 是一种多媒体广播的信息导航业务， 通过电子业务指南用户能够了解移动多 媒体广播业务的相关信息， 在 ESG中包含一张时间编排表， 在时间编排表中 包含文件下载业务中各类应用， 如手机报、 影视片断等的文件的播发开始时 间和播发时长等信息。
本实施方式中， 客户端为用户提供一个文件下载业务的定制界面， 该定 制界面基于时间编排表， 由用户选择自己喜欢或者关注的文件， 客户端将用 户选择的待下载文件的播发信息保存到文件下载设置表中。 客户端在到达用 户选择接收的某个待下载文件的播发开始时间时， 调用文件下载单元， 切换 到相应的信道上， 进行文件下载。
文件下载结束后， 客户端将下载的文件保存在本地的存储介质上并关闭 文件下载单元， 同时显示一个提示标识， （类似收到短信或者彩信的标识） 提示用户收到新文件。 用户选择查看时， 就可以进入文件下载目录， 打开相 应的文件进行阅读或者播放。
下面结合附图对本发明的具体实施方式进行详细说明。

图 2为客户端从时间编排表中提取出文件播发信息生成的定制界面， 其 中， 包括多条文件播发信息， 每条文件播发信息中包括： 主题和开始时间等 文件的主要描述信息。
上述时间编排表通常釆用 XML ( Extensible Markup Language, 可扩展标 记语言）格式，客户端可通过内部的文件解析器从 XML格式的时间编排表中 读取出相应字段， 字段的内容即为文件播发信息。
104: 用户选择待下载文件， 客户端判断用户所选择的待下载文件是否已 订购， 如果是， 则执行步骤 105; 如果否， 则执行步骤 106;
客户端可通过查询 CA (认证授权 )卡或者 SIM (客户识别模块 )卡上的 移动多媒体广播权限信息来判断用户是否订购了某文件。
105: 客户端读取用户所选的待下载文件的播发信息， 并保存到文件下载 设置表中， 执行步骤 107;
如图 3所示， 例如， 用户对上述一周财经（视频）和多媒体手机报两个 下载业务感兴趣， 对其进行选择， 如果用户已订购了这两个下载业务， 则客 户端将用户选择的这两个待下载业务的播发信息保存到文件下载设置表中。
106: 客户端提示用户所选择的待下载文件未订购， 需到运营商处订购， 同时将该文件显示为不能选择；
107:客户端根据文件下载设置表中每个待下载文件的播发开始时间配置 并启动定时器， 以便在文件开始播发时触发下载；
