移动终端和web终端之间互连及流传输和流媒体播放的方法 技术领域
本发明总体上涉及移动通信领域，特别地，涉及一种在移动终端和web终端之间进行互连以及实现二者之间流同步传输和流媒体播放的方法和***。
背景技术
目前，例如移动电话、平板电脑、移动媒体播放器的移动电子设备已经在人们日常生活中越来越流行使用。移动设备已经有逐渐取代传统个人电脑的趋势，成为个人信息的存储中心。然而，个人电脑在很多应用领域中，凭借其大幅的显示屏幕、便利的输入方式以及更为多样的软件和操作***仍然有其不可替代的作用。因此人们在日常生活中，经常需要在移动设备和个人电脑之间进行信息的传递、同步和交互。
传统的在移动电子设备和个人电脑之间传输文件的方法例如使用数据线将个人电脑与电子设备连接，或者通过网盘等网络中转方式。但这些方法是非常耗时且十分麻烦的，用户的体验十分不好。例如，数据线的方式使得用户需要额外准备硬件，为用户带来不便。另外，很多时候需要额外安装驱动程序才能实现除了传输文件之外的其他更为复杂的功能。网盘等网络中转方式需要用户处在网络状况较好的环境中，如果网络状况较差且用户需要交互传输的文件体积较大，就难以实现良好的传输效果。
此外，WiFi技术可以提供移动电子设备和个人电脑之间的传输和较高的传输速度。然而，在以往常规的用WiFi技术实现文件传输的方案中，通常需要接入点(AP)。接入点用作在移动电子设备和个人电脑之间的无线网络中继，个人电脑和移动设备必须同时连接到该无线网络中继上才能实现互连。在由AP为主导形成的网络中，如果断开AP，那会破坏整个网络，同时也会破坏移动设备和个人电脑之间的连接。
蓝牙技术等短距离近场通信技术现在也已经越来越多被用来实现在移动电子设备之间传输文件。然而，蓝牙技术通常无法提供高速的文件传输。另外，个人电脑通常并不是都配备有蓝牙模块，从而使得双向连接通 信无法实现。
另外，由于智能手机的多功能性和便携性，用户经常通过智能手机拍摄照片、录制音乐、视频等，而受限于智能手机较小的屏幕，用户时常需要在个人电脑或其他大屏幕显示器上下载或观看手机上存储的照片、音乐、视频等。由于这些文件通常体积较大，因此如何能够在移动电子设备和个人电脑互连的基础上稳定高速地传输这些体积较大的文件，也是本领域亟待解决的一个问题。
因此，需要一种在移动电子设备和个人电脑之间实现可靠、高速、相对较长传输距离的互连方案，从而解决现有技术中的上述问题。

移动终端110和web终端120可分别经过任意类型的第一网络140与服务器端130之间进行双向通信。所述第一网络140例如选自诸如内联网之类的局域网(“LAN”)和诸如互联网之类的广域网(“WAN”)。第一网络140可被配置为支持利用多种协议设置格式的信息的传输。另外，第一网络140可以是公共网络、专用网络或其组合。第一网络140还可以利用任何一种或多种类型的物理介质来实现，其中包括与多个服务提供商相关联的有线通信路径和无线通信路径。无线通信方式例如WiFi或WLAN、GPRS、蜂窝网络，例如GSM网络、3G网络、LTE网络或CDMA网络。
移动终端110和web终端120之间也可以之间建立直接的网络连接，通过第二网络150进行双向通信。所述第二网络150采用的协议方式例如是http轮询结合WebSocket直连的方式。
移动终端110可以是智能电话、个人数字助理(PDA)、平板电脑、多功能移动终端或者包括计算功能和数据通信能力的任何其他移动设备。移动终端110包括app接口应用111(如图1b所示)及其包括的文件拆分/合并单元112。App应用111例如定制应用(app)，用于与具备web能力的应用进行双向通信。文件拆分/合并单元112用于根据从服务器端130的文件阈值设定模块135中获取的文件分割大小阈值对要上传至服务器端130的文件进行拆分后上传，以及对从文件中转存储器136取回的文件块按照文件名称的索引进行排序合并。这将在下文描述文件中转存储器136时详细介绍。
web终端120可以是台式计算机、膝上型计算机、笔记本电脑、平板电脑、游戏机、智能电视等任何支持web协议的终端设备。web终端120包括web接口121及其包括的文件拆分/合并单元122(如图1b所示)。web接口121例如web浏览器。在一些实施例中，相应web终端120包括用于请求、解析、显示、执行网页以及执行包括在网页中的应用的浏览器应用。浏览器应用128可以是允许用户搜索、浏览和/或使用URL(统一资源定位符)或URI(统一资源标识符)所识别的资源(例如，网页和web服务)的任何应用。“URL”在本文用来意指文档的网络地址或位置。在该情形下，“文档”指可以由web浏览器或其他应用使用的任何格式的任何文档或内容，包括但不限于：字处理文档、电子表格文档、演示文档、绘图、网页、文本、图像、音频、视频等。
文件拆分/合并单元122用于根据从服务器端130的文件阈值设定模块135中获取的文件分割大小阈值对要上传至服务器端130的文件进行拆分后上传，以及对从文件中转存储器136取回的文件块按照文件名称的索引进行排序合并。这将在下文描述文件中转存储器136时详细介绍。
移动终端110包括一个或多个计算设备，该一个或多个计算设备可以从用户接收输入，并可呈现输出，因此移动终端110还包括I/O接口(输入/输出接口)112，可接收一个或多个输入并呈现输出。例如，输入接口可包括摄像头、触摸板、触摸屏、触屏笔、麦克风中的一个或多个。另外，通过输出接口可呈现输出，以输出用户的控制操作指令或来 自其他用户的反馈信息等。输出接口包括显示屏、一个或多个扬声器和触觉接口中的一个或多个。
图1b示出了包含服务器端的具体架构和组成的***框图。如图1b所示，服务器端130包括二维码模块131、网络接入模块132、网络状况标志符133、地址生成模块134、文件阈值设定模块135和文件中转存储器136。
二维码模块131用于生成供移动终端110扫描的二维码。根据本发明的一个实施例，二维码包含了通用唯一识别码(UUID)，UUID是唯一标识码。移动终端110通过扫描该二维码表应的UUID连接到服务器端130以请求获取唯一的连接地址和会话(session)。
网络接入模块132用于相应移动终端110扫描二维码成功后判断移动终端110和web终端120各自的网络连接状况，以针对不同的网络连接状况进行移动终端110和web终端120之间的适配性连接，从而建立移动终端110和web终端120之间的连接。优选地，所建立的连接为http长连接。该连接可以连续发送多个数据包，在连接保持期间，如果没有数据包发送，为了确保两个终端保持连接，会在规定间隔时间内发送检测数据包(即心跳包)，移动终端110和web终端120之间需要发送检测数据包以维持此连接。
具体地，网络接入模块132获取移动终端110和web终端120各自连接到服务器端130的网络状态，判断移动终端110和web终端120的网络连接是否处于同一网络下。根据本发明的同一网络是指在同一个路由器下同一网段能直接连接，而不需要经过外网。
并针对是否处于同一局域网络将网络状况标志符133设置不同的状态。例如，若处于同一网络内，则在网络状况标志符133中设置一标识，例如数字1；若不处于同一网络，则不在网络状况标志符133中设置标识，或者设置另一不同的标识，例如数字0。
根据本发明的一个实施例，网络接入模块132会定期地获取移动终端110和web终端120各自连接到服务器的网络状态，以判断移动终端110和web终端120的网络连接是否处于同一局域网下的状态是否发生变化，并针对变化了的网络状态更新网络状况标志符133。所述定期获取的频率例如可以是每30秒一次。该定期发送的信号也被称为“心跳信号”，该信号还可以用来检测移动终端110和web终端120是否仍连接到服务器端130。例如当未接收到移动终端110或web终端120反馈 的心跳响应信号超过一定的次数，服务器端130即可判断移动终端110或web终端120已经断开与服务器端130的连接。
网络状况标志符133用于存储移动终端110和web终端120之间由于不同的网络连接状况而产生适配性连接的标识。例如，移动终端110和web终端120处于同一网络内，网络状况标志符133中设置一标识；若不处于同一网络，则设置另一不同的标识。
地址生成模块134，用于生成需要在移动终端110和web终端120之间传送的文件地址。当移动终端110和web终端120之间根据本发明的方法建立了连接之后，用户可以选择通过移动终端110上传文件至Web终端120，或者从Web终端120下载文件到移动终端110上。当用户发出此类移动文件的请求时，地址生成模块134为所传送的文件生成基于网络的地址，例如URL，传送给需要下载文件的移动终端110或web终端120，移动终端110和web终端120只需访问该地址即可下载到该文件，从而实现文件的传送。
文件阈值设定模块135，用于在当web终端120通过服务器端130以下载或播放的文件传送方式传输移动终端110中的文件时，根据所传输的文件大小设定文件分块的阈值。当传送体积较大的文件时，根据本发明的流同步和流媒体传输的方式，可以将文件分割成多个文件块进行传送。文件阈值设定模块135可以采集文件的大小信息，从而设定要分割的每个文件块的大小阈值，从而进行传输。
根据本发明的一个实施例，文件阈值设定模块135还可以根据web终端120和/或移动终端110连接到服务器端130的网络状况来动态地设置文件传送的阈值。例如，当网络状况良好时，可以设定较大的阈值，即分割的单个文件的大小较大，以减小传送的次数，从而加快传输速度。相反地，当网络状况较差时，可以设定较小的阈值，即分割的单个文件的大小较小，以增大传送的次数，保证单次传送的质量。
文件中转存储器136，用于中转存储根据文件阈值设定模块135设定的文件分块的大小而分割传送的各个文件块。下表1示出了根据本发明的一个实施例的文件中转存储器136中存储文件块的方式。如表1所示，文件中转存储器136存储的格式包括用户ID、文件名、文件块分区以及文件块地址。用户ID标识了使用服务器端中转文件的移动终端110的用户身份，文件名标识该用户ID下传送的文件名称，而文件块分区中存储了该用户传送的某个文件的其中某个文件块。文件块地址是用 来发送给移动终端110或web终端120的，以便使移动终端110或web终端120通过直接访问该地址来下载相应的文件块。
例如，用户ID为0024的用户，传送001号文件，该001号文件被分成若干个文件块0001、0002……0004……进行传送。通过这种方式，通过用户ID和文件名的索引，就可以容易地将分割成多块的文件进行单独存储。这样，可以在同一存储区中存储不同用户的不同文件的不同子文件块。
如表1所示，根据本发明的一个实施例，用户ID和文件名可以不连续存储，文件块分区也可以不连续存储，例如可以以随机的方式进行存储。当移动终端110或web终端120从服务器端130取回文件块时，只需同时取回其相应的用户ID和文件名，即可通过其各自的文件拆分/合并单元根据索引合并成分割前的完整文件。
用户ID 文件名 文件块分区 文件块地址

图2示出了用户通过移动终端110借助服务器端130与web终端120进行交互连接的方法流程图。如图2所示，
在步骤205，用户通过web终端120向服务器端130发出连接请求。具体地，用户可以通过启动web终端120上的浏览器，并在浏览器地址栏中输入www.****.cc的地址信息来发送连接请求。
接着，在步骤210，服务器端130会应web终端120发出的连接请 求发送二维码信息给web终端120，并在步骤220中在web终端120上呈现该二维码信息。所述二维码信息包含了通用唯一识别码(UUID)，UUID是唯一标识码。移动终端110通过扫描该二维码表应的UUID连接到服务器端130以请求获取唯一的连接地址和会话(session)。
接下来，在步骤225，用户通过移动终端110扫描web终端120上的二维码信息。例如，通过移动终端110上带有的摄像头进行扫描。具体地，用户启动移动终端110上的app软件，app软件会提示用户扫描二维码从而实现连接。
接着，响应于用户扫描二维码的操作，移动终端110和web终端120分别在步骤230a和步骤230b向服务器端发起连接请求，并将自身的网络连接状况发送给服务器端130。具体的，所述网络连接状况为通过何种网络连接至服务器端。
在步骤235，服务器端130通过获取的移动终端110和web终端120各自连接到服务器的网络状况，判断移动终端110和web终端120的网络连接是否处于同一局域网下，并针对是否处于同一局域网络将网络状况标志符设置不同的状态。例如，若处于同一网络内，则在网络状况标志符133中设置一标识，例如数字1；若不处于同一网络，则不在网络状况标志符133中设置标识，或者设置另一不同的标识，例如数字0。
接着，服务器端130分别在步骤240a和步骤240b向移动终端110和web终端120发送连接建立许可，从而在移动终端110和web终端120之间建立连接。优选地，建立http长连接。
接着，在步骤245，在移动终端110呈现连接后的界面。图3a示意性地示出了根据本发明一个实施例的示例性移动终端110的连接界面。如图3a所示，移动终端110的呈现界面中，分为位于界面顶部的项目栏301和位于项目栏301下方的文件示例栏302。在项目栏301中，将可以同步传输的文件示意性地分为“照片”、“图库”、“音乐”、“视频”、“文档”等项目，用户可以在不同项目之间进行切换。本领域技术人员可以理解的是，上述项目仅仅是示例性的，可以根据不同需求增加或减少新的项目。在每个选中的项目下，会按照时间、文件大小等不同的分类排序方式对属于该项目的文件进行展示，优选以缩略图、文件名、文件图标等方式进行展示。
接着，在步骤250，将移动终端110要进行同步传送的文件的统计信息发送至服务器端130，再在步骤255中经服务器端130将这些信息 转发至web终端120。优选地，所述同步统计信息包括要进行同步连接传送的文件数目、文件种类、每个种类各自的文件数目。还可以包括移动终端110的一些基本信息，如操作***型号、手机用户基本信息、版本型号等等。
接着在步骤260，在web终端120呈现连接后的界面，并同时呈现经服务器端130转发的同步统计信息。图3b示意性地示出了根据本发明一个实施例的示例性web终端120的连接呈现界面。如图3b所示，在web终端120的呈现界面中，分为位于界面左侧的导航栏303和位于导航栏303右侧的文件统计栏304。在导航栏303中，将可以同步传输的文件示意性地分为“照片”、“图库”、“音乐”、“视频”、“文档”、“短信”、“文件夹”、“应用”等项目，用户可以在不同项目之间进行切换。还可以增加“主页”项目以浏览总体的文件统计信息。本领域技术人员可以理解的是，上述项目仅仅是示例性的，可以根据不同需求增加或减少新的项目。在“主页”项目下，在文件统计栏304中会按照文件的类型展示各种文件的数量。例如图3b中示例性的音乐图标305a，以及其下方的音乐数量(39)图标305b。另外，还可以呈现所传送的移动终端110的一些基本信息，例如在文件统计栏304中下方的306处呈现的移动终端110的存储容量信息，以便于用户通过web终端120管理移动终端110。
当用户需要将web终端120和移动终端110断开连接时，可以通过关闭web终端120的web接口(例如浏览器)或者关闭app应用任意一者或二者来实现断开。
根据本发明的另一实施例，当用户未主动断开连接时，或者用户断开移动终端110或web终端120任意一者的网络连接时，服务器端130也可以通过向移动终端110和web终端120发送心跳信号来检验是否仍然保持连接。例如，当未接收到移动终端110或web终端120反馈的心跳响应信号超过一定的次数，服务器端130即可判断移动终端110或web终端120已经断开与服务器端130的连接。服务器端130于是可以断开移动终端110和web终端120之间的连接。具体地，当服务器端130判断出移动终端110或web终端120已经断开与服务器端130的连接后，服务器端130向web终端120发送命令，web终端120返回到初始未连接的状态，例如，呈现二维码的页面状态。服务器端130同时还向移动终端110发送命令，使得移动终端110也返回至初始未连接的状 态。也即，当服务器端130检测到移动终端110或web终端120其中任意一者断开连接时，会立即同时断开另一者，以确保信息的安全。
根据本发明的一个实施例，当移动终端110或web终端120以移动网络方式(例如GPRS、3G、4G等)连接到服务器端130时，服务器端120可以在检测心跳信号时，同时检测移动终端110或web终端120所处的移动网络小区状况。当移动终端110或web终端120其中任意一者所连接的小区发生切换时，可以判断出移动终端110或web终端120已经离开另一者一段物理距离。为了确保文件传送的安全性，可以设定在移动终端110和web终端120两者离开特定的距离后，断开两者之间的连接。
文件流同步传输方式
图4示出了用户通过web终端120借助服务器端130传输位于移动终端110上的文件的方法流程图。如图4所示，
在步骤405，用户通过web终端120向服务器端130发出传送文件的请求。根据本发明的一个实施例，用户可以首先选择要传送的文件类型所在的类别。例如“照片”、“图片”、“音乐”、“视频”或者“文档”等等。
在步骤410，基于用户的选择请求，服务器端130向移动终端110请求所选类别下全部文件的摘要信息，所述摘要信息包括但不限于文件缩略图、文件大小信息、文件截图等等。然后，在步骤415中将所获取的文件类别的摘要信息发送至web终端120。优选地，以压缩或加密的方式传送所选类别下全部文件的摘要信息。
根据本发明的一个实施例，当用户首次请求某个传送文件的类别时，服务器端130会向移动终端110请求所选类别下全部文件的摘要信息。之后，这些摘要信息可以缓存在web终端120中，例如保存在web终端120的浏览器缓存中。之后用户再次选择该类别时，就无需再次从移动终端110传送，而是直接从缓存中调取，直到web终端120和移动终端110之间断开为止。根据本发明的一个实施例，当web终端120和移动终端110之间断开后，所缓存的文件摘要信息会被清除。
图5a和图5b分别示意性地示出了根据本发明一个实施例的示例性文件摘要界面。其中图5a显示的是音乐文件的文件摘要信息，图5b显示的视频文件的文件摘要信息。如图5a所示，当用户在web终端120 选择的文件类别是“音乐”时，服务器端130向移动终端110请求所选类别下全部文件的摘要信息，所述摘要信息包括文件的名称、音乐时长、音乐文件类型、创建时间等等。如图5b所示，当用户在web终端120选择的文件类别是“视频”时，服务器端130向移动终端110请求所选类别下全部文件的摘要信息，所述摘要信息包括文件的名称和视频中某一帧的截图。
回到图4，在步骤420，用户在web终端120选择某个想要下载的文件，向服务器端130发送传送该文件的请求。接着在步骤425，服务器端130查询网络状况标识符，根据网络状况标识符的标识情况建立移动终端110和web终端120之间的连接。具体地，当网络状况标识符标识出web终端120和移动终端110处于不同网络下时，可以通过服务器端130的中转来传送文件，进入步骤430。
在步骤430，在服务器端130开启web上传服务。在步骤435，根据文件摘要信息中的文件大小信息，由文件阈值设定模块135设定要分割的子文件块的文件大小阈值，然后将该阈值发送给移动终端110进行文件分割和传送。例如，当阈值为1M时，表示需要将要传送的文件分割成每个大小为1M的子文件块进行传送。根据本发明的一个实施例，当要传送的文件足够小时，可以无需进行分割，此时可以将文件阈值大小设定为一特殊标记，当移动终端110读取到该特殊标记时，无需分割，直接将文件上传至服务器端130。
在步骤440中，将移动终端110上要传送的文件上传至服务器端130。在步骤445中，在服务器端130的文件中转存储器136中按照表1描述的索引方式，进行存储，并为每个文件块生成该文件块的地址(url)。在步骤450中，将所存储并生成的对应文件地址发送给web终端120。优选地，当移动终端110传送的文件以分块的形式传送时，将每一个文件片段的地址以此发给web终端120。在步骤455，web终端120访问收到的地址，下载文件。可选地，当将文件分成多个文件块进行传送时，还需要进行步骤460，即在文件拆分/合并单元122进行文件块的合并，从而在web终端120形成完整的传送文件。
根据本发明的一个实施例，可以将多个被分割的文件块同步进行传送，以进一步提高文件传送的效率。可选地，文件块无需按照分割的先后顺序进行传送，而是可以以随机的传送顺序进行传送。在web终端120，也可以以随机的顺序下载接收各个文件块。
根据本发明的另一实施例，当网络状况标识符标识出web终端120和移动终端110处于同一网络下时，可以通过建立web终端120和移动终端110之间的直连来传送文件。直连的方式避免了服务器端130的中转，提高了传送速度和传送效率。在直连的情况下，由于网络状况较好，可以无需拆分文件而进行整个文件的传输。具体地，移动终端110会自动启动一个web服务，为web终端120所请求传送的文件时生成一个文件地址(url)。然后，发送该文件地址给web终端120。接着web终端120访问该地址以下载得到所请求的文件。
图6示出了用户通过web终端120借助服务器端130向移动终端110传送文件的方法流程图。如图6所示，
在步骤605，用户通过web终端120向服务器端130发出传送文件的请求，发送请求传送文件的类别。根据本发明的一个实施例，用户可以首先选择要传送的文件类型所在的类别。例如“照片”、“图片”、“音乐”、“视频”或者“文档”等等。
在步骤610，基于用户的选择请求，服务器端130向移动终端110请求所选类别下全部文件的摘要信息，所述摘要信息包括但不限于文件缩略图、文件信息、文件截图等等。然后，在步骤615中将所获取的文件类别的摘要信息发送至web终端120。优选地，以压缩或加密的方式传送所选类别下全部文件的摘要信息。
根据本发明的一个实施例，当用户首次请求某个传送文件的类别时，服务器端130会向移动终端110请求所选类别下全部文件的摘要信息。之后，这些摘要信息可以缓存在web终端120中，例如保存在web终端120的浏览器缓存中。之后用户再次选择该类别时，就无需再次从移动终端110传送，而是直接从缓存中调取，直到web终端120和移动终端110之间断开为止。当web终端120和移动终端110之间断开后，所缓存的文件摘要信息会被清除。
在步骤620，用户选择某个想要传送至移动终端110的文件，向服务器端130发送传送该文件的请求，并发送所传送文件的摘要信息。根据本发明的一个实施例，向移动终端110传送文件可以采取多种方式。图5a和图5b示出了其中一种方式。如图5a和图5b所示，用户可以通过点击左上角的“添加音乐”按钮501或“添加电脑视频”按钮502来选择要传送至移动终端110的文件。或者，也可以通过直接将文件拖曳到相应类型的项目页面下，从而触发文件向移动终端110的传送。所传 送文件的摘要信息例如包括文件的大小，用于使服务器端130根据文件的大小设定文件分割的阈值。
接着在步骤625，服务器端130查询网络状况标识符，根据网络状况标识符的标识情况建立移动终端110和web终端120之间的连接。具体地，当网络状况标识符标识出web终端120和移动终端110处于不同网络下时，可以通过服务器端130的中转来传送文件，进入步骤630。
在步骤630，在服务器端130开启web上传服务。在步骤635，根据所请求传送文件摘要信息中的文件大小信息，由文件阈值设定模块135设定要分割的子文件块的文件大小阈值，然后将该阈值发送给移动终端110进行文件分割和传送。例如，当阈值为1M时，表示需要将要传送的文件分割成每个大小为1M的子文件块进行传送。根据本发明的一个实施例，当要传送的文件足够小时，可以无需进行分割，此时可以将文件阈值大小设定为一特殊标记，当移动终端110读取到该特殊标记时，无需分割，直接将文件上传至服务器端130。
在步骤640中，将移动终端110上要传送的文件上传至服务器端130。在步骤645中，在服务器端130的文件中转存储器136中按照表1描述的索引方式，进行存储，并为每个文件块生成该文件块的地址(url)。在步骤650中，将所存储并生成的对应文件地址发送给移动终端110。优选地，当web终端120传送的文件以分块的形式传送时，将每一个文件片段的地址以此发给移动终端110。在步骤655，移动终端110访问收到的地址，下载文件。可选地，当将文件分成多个文件块进行传送时，还需要进行步骤660，即在移动终端110中的文件拆分/合并单元112进行文件块的合并，从而在移动终端110形成完整的传送文件。
根据本发明的一个实施例，可以将多个文件块同步进行传送，以进一步提高文件传送的效率。可选地，文件块无需按照分割的先后顺序进行传送，而是可以以随机的传送顺序进行传送。在移动终端110，也可以以随机的顺序下载接收各个文件块。
根据本发明的另一实施例，当网络状况标识符标识出web终端120和移动终端110处于同一网络下时，可以通过建立web终端120和移动终端110之间的直连来传送文件。直连的方式避免了服务器端130的中转，提高了传送速度和传送效率。在直连的情况下，由于网络状况较好，可以无需拆分文件而进行整个文件的传输。具体地，web终端120会自动启动一个web服务，为移动终端110所请求传送的文件时生成一个文 件地址(url)。然后，发送该文件地址给移动终端110。接着移动终端110访问该地址以下载得到所请求的文件。
文件流媒体播放方式
图7示出了用户通过web终端120借助服务器端130以流媒体方式播放位于移动终端110上的文件的方法流程图。如图7所示，
在步骤705，用户通过web终端120向服务器端130发出播放文件的请求。根据本发明的一个实施例，用户可以首先选择要播放的文件类型所在的类别。例如“音乐”或“视频”等等。
在步骤710，基于用户的选择请求，服务器端130向移动终端110请求所选类别下全部文件的摘要信息，所述摘要信息包括但不限于文件缩略图、文件大小信息、文件截图等等。然后，在步骤715中将所获取的文件类别的摘要信息发送至web终端120。优选地，以压缩或加密的方式传送所选类别下全部文件的摘要信息。
根据本发明的一个实施例，当用户首次请求某个播放文件的类别时，服务器端130会向移动终端110请求所选类别下全部文件的摘要信息。之后，这些摘要信息可以缓存在web终端120中，例如保存在web终端120的浏览器缓存中。之后用户再次选择该类别时，就无需再次从移动终端110传送，而是直接从缓存中调取，直到web终端120和移动终端110之间断开为止。根据本发明的一个实施例，当web终端120和移动终端110之间断开后，所缓存的文件摘要信息会被清除。
在步骤720，用户在web终端120选择某个想要播放的文件，向服务器端130发送播放该文件的请求。例如可以通过点击图5b所示的播放箭头图标503来发出该播放请求。接着在步骤725，服务器端130查询网络状况标识符，根据网络状况标识符的标识情况建立移动终端110和web终端120之间的连接。具体地，当网络状况标识符标识出web终端120和移动终端110处于不同网络下时，可以通过服务器端130的中转来传送文件，进入步骤730。
