Description

一种传输文件的方法及终端
本申请要求于2018年5月17日提交中国国家知识产权局、申请号为201810476102.9、发明名称为“一种传输文件的方法及终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信领域，尤其涉及一种传输文件的方法及终端。
背景技术
现在的终端一般都会具备多种数据通信能力，即采用多种数据通信技术进行数据传输的能力。上述多种数据通信技术可以包括如下数据通信技术，比如，蓝牙(Bluetooth)通信技术、近场通信(Near Field Communication，NFC)通信技术、OTG(On The Go)通信技术、wifi直连(Wi-Fi Direct)通信技术、无线局域网(Wireless Local Area Networks，wlan)通信技术、通用分组无线服务(General Packet Radio Service，GPRS)通信技术、移动通信技术(mobile communication)等通信技术。
采用每一种数据通信技术建立通信连接都有自身的学习成本，配对连接的方式也不近相同。比如采用蓝牙通信技术建立通信连接时，需要一方打开监听，另外一方搜寻识别。有的手机为了安全、耗电方面的考虑，打开监听以后会在几十秒以后自动关闭监听。当需要建立蓝牙通信连接时，需要用户手动打开监听，这些会给用户造成使用上的困扰。此外还有时候手机所处的网络环境复杂，比如距离稍远，信号不好，配置繁琐，可能导致用户很难把一个稍大的文件，或者大量的文件有效的分享成功。
一种现有技术中，采用蓝牙、wifi直连、NFC、wifi等近距离无线通信技术通过单一途径传输文件。当一个终端用户试图分享一个文件给另外一个终端的时候，双方约定好使用的传输方式，比如近距离的蓝牙、wifi直连、NFC、wifi等，并且打开相应的开关和端口。当一个终端发现另外一个终端并创建连接以后就可以进行文件的传输。
另一种现有技术中，采用GPRS，WLAN等远距离无线通信技术通过单一途径传输文件。需要传输文件的两个终端共同连接相同的服务器、或者路由器创建间接连接，然后进行文件传输。
又一种现有技术中，采用蓝牙、wifi直连简单组合传输文件技术，比如要求同时开启wifi和蓝牙，通过蓝牙快速找到对方，然后通过wifi直连传输文件。需要同时打开wifi和蓝牙，有一种不打开不能完成传输，仅限于wifi和蓝牙两种连接方式，使用范围很局限。该方法实质上也属于通过单一途径传输文件。
上面三种现有技术中，都是通过单一途径传输文件，由于传输距离、传输环境制约，用户主观选择的传输途径可能并不是最优的。当用户选择一种传输途径进行文件传输的时候，可能会因为距离变远、信号不好、网络不好等因素发生传输中断，需要用户手动进行重试或者选择其它传输途径。并且，即便是两个终端之间存在多种传输途径，也只能选择一种传输途径进行连接。使用繁琐、传输效率低。

具体实施方式
现在的平板、笔记本、手机等终端都会有蓝牙、wifi、GPRS、NFC等多种数据传输能力。本发明设计了一种通过多路径高效传输文件的方式。
第一终端(即发送文件的终端)接收向第二终端(即接收文件的终端)传输文件的请求；所述第一终端根据所述第一终端和所述第二终端共同支持的多种通信方式与所述第二终端建立多条第一通信连接；所述第一终端通过所述多条第一通信连接中的至少一条通信连接向所述第二终端传输文件。
本发明实施例，第一终端接收到向第二终端传输文件的请求后，不是直接使用已经建立的一条通信连接或根据用户选择的一种通信方式建立的一条通信连接向第二终端传输文件，而是根据所述第一终端和所述第二终端共同支持的多种通信方式与所述第二终端建立多条第一通信连接，从而所述第一终端可以根据待传输的文件数量或文件大小通过所述多条第一通信连接中的至少一条通信连接向所述第二终端传输文件，由于建立多条通信连接的过程是终端自动实现的，无需用户手动操作，因此使用简单，并且可以使用多条通信连接协作传输文件或多条通信连接中传输质量较高的通信连接传输文件，因此传输效率高。
在一个示例中，通过任意一种途径创建通信连接后，自主发现、协商其它共同具有的传输途径(即通信方式)，自动创建多条通信连接，多途径共同传输文件。
作为一种非限定的实现方式，本发明实施例中，可以在要传输文件的两个终端上都安装了本文件传输软件，比如在文件管理器、照片库等文件管理软件中，发起分享文件的动作时，可以使用本文件传输软件。本领域技术人员可以理解，采用硬件实现也是可以的。
在一个示例中，对于处于网络离线状态(未连接互联网)的两个终端，在启动文件传输软件以后会自动扫描本机存在的可以用于传输的方式，并提示用户选择一种，比如NFC，当两个终端通过这种方式发现对方并建立连接以后，两个终端会自动匹配两个终端可能的其它连接方式，比如蓝牙、wlan、wifi直连等。自动通过NFC交换蓝牙id，wlan监听ip和端口，wifi直连密码等连接参数，随后依次尝试进行局域网内直连、wifi直连、蓝牙等通信连接。
在一个示例中，当用户传输多个文件的时候，终端会把文件分到不同的传输路径进行传输，当用户传输大文件的时候，终端会把文件分割成多个小文件并进行标记序号，进行多路传输，然后在传输完成后进行文件合并。在多路传输的过程中，会实时监测各路传输途径的稳定性和传输效率，实时调整迁移传输任务到更快速的通道上。
在一个示例中，对于处于网络在线状态(连接互联网)的两个终端，对于协商传输途 径的方式，也可以采用间接的连接方式，比如通过华为会员、QQ等即时通信(Instant Messaging，IM)系统的服务器进行间接连接。两个终端都和IM系统建立连接,通过两者上传的地理位置和在线网络，IM系统可以很快的通知对方，使两个终端相互发现，用户也可以自己选择自己的好友直接进行通信。通过IM系统，两个终端完成上述传输途径的协商过程，并进行下面的创建连接、文件传输过程。
本发明实施例目的是更方便传输文件，包括两个终端自动发现自身可以用于传输文件的途径，并自动完成传输途径协商，并完成连接参数交换，多途径创建连接进行传输。一方面，提高了终端间传输文件的便捷性；另一方面，充分利用终端间共同具有的传输途径进行文件传输，提高传输效率。
图1为本发明实施例提供的传输文件的方法基于的一种应用场景示意图。参照图1，用户101使用的终端103向用户102使用的终端104传输文件。一种情况是终端103和终端104均处于网络离线状态，即终端103和终端104之间不存在终端103通过服务器105到终端104的间接通信连接。这种情况下，终端103和终端104之间仅通过近距离通信方式建立通信连接，并通过建立的通信连接传输信息或文件，例如，终端103和终端104先建立一条通信连接，通过该通信连接交互支持的多种通信方式的标识，然后根据终端103和终端104共同支持的多种通信方式建立多条通信连接，通过终端103和终端104之间的多条通信连接协作传输文件。另一种情况是终端103和终端104均处于网络在线状态，即终端103和终端104之间存在终端103通过服务器105到终端104的间接通信连接。这种情况下，终端103和终端104之间既可以通过近距离通信方式建立通信连接又可以通过远距离通信方式建立通信连接，并通过建立的通信连接传输信息或文件，例如，终端103和终端104先通过该间接通信连接交互支持的多种通信方式的标识，然后根据终端103和终端104共同支持的多种通信方式建立多条通信连接，通过终端103和终端104之间的多条通信连接协作传输文件。
可以理解的是，终端103和终端104之间的距离较近，满足近距离通信的条件。
在一个示例中，终端103和终端104均登录了服务器105，服务器105可以确定终端103和终端104之间的距离满足近距离通信的条件，并向终端103和终端104发送通知信息，以使终端103和终端104互相发现。
本发明实施例，由于终端103和终端104可以自动建立多条通信连接，并通过多条通信连接协作传输文件，因此一方面无需用户手动操作，使用简单，另一方面可以使用多条通信连接协作传输文件或多条通信连接中传输质量较高的通信连接传输文件，因此传输效率高。
图2为本发明实施例提供的一种传输文件的方法通信示意图，该实施例可以基于图1所示的应用场景，该方法包括：
步骤201，第一终端接收向第二终端传输文件的请求。
例如，第一终端接收到了用户分享文件的指令，从而确定需要向第二终端传输文件。
可以理解的是，第一终端为发送文件的终端，第二终端为接收文件的终端。
步骤202，第一终端根据所述第一终端和所述第二终端共同支持的多种通信方式与所述第二终端建立多条第一通信连接。
在一个示例中，在步骤202之前，所述第一终端与所述第二终端先建立第二通信连接；所述第一终端通过所述第二通信连接从所述第二终端接收信息，所述信息用于建立所述多条第一通信连接。根据该实施方式，所述第一终端与所述第二终端先建立第二通信连接；所述第一终端通过所述第二通信连接从所述第二终端接收信息，从而第一终端根据从第二终端接收到的信息建立所述多条第一通信连接。
可以理解的是，出于经济方面的考虑，上述多条第一通信连接通常为采用近距离通信方式建立的通信连接，上述第二通信连接可以为采用近距离通信方式建立的通信连接，也可以为采用远距离通信方式建立的通信连接。当上述第二通信连接为采用近距离通信方式建立的通信连接时，上述第二通信连接可以包括在上述多条第一通信连接中，当上述第二通信连接为采用远距离通信方式建立的通信连接时，上述第二通信连接不包括在上述多条第一通信连接中。当然了，如果不考虑经济因素，上述第一通信连接和第二通信连接既可以为采用近距离通信方式建立的通信连接，也可以为采用远距离通信方式建立的通信连接。
例如，所述信息为所述第一终端和所述第二终端共同支持的多种通信方式的标识，其中，所述信息由所述第二终端根据所述第一终端发送的所述第一终端支持的多种通信方式的标识以及所述第二终端支持的多种通信方式的标识确定，其中所述第一终端通过所述第二通信连接向所述第二终端发送所述第一终端支持的多种通信方式的标识。根据该实施方式，第一终端通过所述第二通信连接向所述第二终端发送所述第一终端支持的多种通信方式的标识，由所述第二终端根据所述第一终端发送的所述第一终端支持的多种通信方式的标识以及所述第二终端支持的多种通信方式的标识确定所述第一终端和所述第二终端共同支持的多种通信方式的标识。
又例如，所述信息为所述第二终端支持的多种通信方式的标识，所述第一终端根据所述第一终端支持的多种通信方式的标识以及所述第二终端支持的多种通信方式的标识确定所述第一终端和所述第二终端共同支持的多种通信方式。根据该实施方式，第一终端通过所述第二通信连接从所述第二终端接收所述第二终端支持的多种通信方式的标识，由所述第一终端根据所述第一终端接收的所述第二终端支持的多种通信方式的标识以及所述第一终端支持的多种通信方式的标识确定所述第一终端和所述第二终端共同支持的多种通信方式的标识。
有了所述第一终端和所述第二终端共同支持的多种通信方式的标识，所述第一终端和所述第二终端就可以根据所述共同支持的多种通信方式建立多条第一通信连接；
在一个示例中，所述第一终端显示所述第一终端支持的多种通信方式中每种通信方式的标识；所述第一终端确定用户从所述第一终端支持的多种通信方式中选择的一种通信方式；所述第一终端根据所述用户选择的一种通信方式发现所述第二终端，并与所述第二终端建立所述第二通信连接。根据该实施方式，可以由用户选择一种熟悉的通信方式手动建立第二通信连接，该第二通信连接为直接的通信连接。
在另一个示例中，所述第一终端和所述第二终端通过服务器建立所述第二通信连接。根据该实施方式，该第二通信连接为间接的通信连接。
当第二通信连接为间接的通信连接时，服务器可以使第一终端快速发现并选择第二终端。
例如，所述第一终端从所述服务器接收第一标识集合，所述第一标识集合包括所述第一终端附近终端的标识和/或所述第一终端的关联终端的标识；所述第一终端显示所述第一标识集合；所述第一终端根据用户从所述第一标识集合中选择的所述第二终端的标识确定向所述第二终端传输文件。可以理解的是，上述第一终端的关联终端可以为与第一终端通过服务器有过信息交互的终端，或者还可以为与第一终端建立过关联关系的终端。上述两个终端之间的关联关系可以为两个终端的用户之间的关联关系，例如，两个终端的用户属于同一群组，或两个终端的用户互为好友。根据该实施方式，当第二通信连接为经过服务器建立的间接通信连接时，可以由服务器确定第一终端附近终端的标识和/或所述第一终端的关联终端的标识，便于第一终端快速发现并选择第二终端。
在一个示例中，所述第一终端通过所述第二通信连接与所述第二终端交换所述第一终端和所述第二终端共同支持的多种通信方式中每种通信方式的连接参数；所述第一终端根据所述第一终端和所述第二终端共同支持的多种通信方式中每种通信方式的连接参数与所述第二终端建立多条第一通信连接。根据该实施方式，第一终端和第二终端自动交换每种通信方式的连接参数，无需用户手动设置，使用简单。
可以理解的是，可以预先设定每种通信方式的优先级，按照优先级的高低依次建立多条通信连接。
步骤203，第一终端通过所述多条第一通信连接中的至少一条通信连接向所述第二终端传输文件。
在一个示例中，所述第一终端将每个所述文件作为一个任务；所述第一终端通过所述多条第一通信连接中的至少一条通信连接向所述第二终端传输所述任务。根据该实施方式，所述第一终端将每个所述文件作为一个任务；通过所述多条第一通信连接中的至少一条通信连接向所述第二终端传输所述任务，从而实现传输资源的优化。
在另一个示例中，所述第一终端针对待传输的每个文件，判断文件大小是否小于第一阈值；当判断结果为文件大小小于或等于所述第一阈值时，将文件作为一个任务；当判断结果为文件大小大于所述第一阈值时，根据所述第一阈值将文件划分为多个任务；所述第一终端通过所述多条第一通信连接中的至少一条通信连接向所述第二终端传输所述任务。根据该实施方式，第一终端针对待传输的每个文件，将大文件划分为多个任务，便于多条通信连接协作传输大文件，从而可以进一步实现传输资源的优化。
其中，第一终端可以但不限于基于如下两种方式从所述多条第一通信连接中选择至少一条通信连接。
例如，所述第一终端根据所述任务的数量和所述多条第一通信连接中每条通信连接对应的通信方式的预设优先级，从所述多条第一通信连接中选择至少一条通信连接向所述第二终端传输所述任务。根据该实施方式，可以根据预设规则，例如传输效率的高低、是否会产生扣费等确定每种通信方式的预设优先级，从而使选择的通信连接更能符合用户的需求。
又例如，所述第一终端根据所述任务的数量和所述多条第一通信连接中每条通信连接的传输质量，从所述多条第一通信连接中选择至少一条通信连接向所述第二终端传输所述任务。可以理解的是，第一终端可以周期性监测每条通信连接的传输质量，上述传输质量 可以包括传输稳定性和传输效率，可以通过丢包率等来衡量。根据该实施方式，能够自动选择传输质量佳的通信连接传输任务，无需用户操作，用户体验佳。
又例如，所述第一终端根据所述任务的个数和所述多条第一通信连接中每条通信连接对应的通信方式的预设优先级，从所述多条第一通信连接中选择至少一条通信连接之后，所述第一终端监测预设时间周期内所述多条第一通信连接中每条通信连接的稳定性和传输效率；根据所述预设时间周期内所述多条第一通信连接中每条通信连接的稳定性和传输效率，更新所述多条第一通信连接中每条通信连接对应的通信方式的实时优先级；将所述实时优先级低于预设级别的通信连接上的任务迁移到所述实时优先级高于预设级别的通信连接上进行传输。
需要说明的是，第一终端建立通信连接的过程可以包括两个阶段。第一个阶段，先建立一条通信连接(即第二通信连接)，通过该条通信连接交互两个终端支持的多种通信方式的标识，以确定两个终端共同支持的多种通信方式；第二个阶段，根据两个终端共同支持的多种通信方式，建立多条通信连接(即多条第一通信连接)。步骤203中，第一终端可以仅通过第二个阶段建立的多条第一通信连接协作向第二终端传输文件，也可以通过第一个阶段建立的一条第二通信连接和第二个阶段建立的多条第一通信连接协作向第二终端传输文件。
在一个示例中，步骤203之前，所述方法还包括：所述第一终端向所述第二终端发送待传输文件的文件信息，所述文件信息包括文件个数、每个文件的文件编号、每个文件的文件大小和每个文件的文件摘要中的至少一项。
在一个示例中，所述方法还包括：所述第一终端监测预设时间周期结束时待传输文件中每个文件的传输进度；所述第一终端显示每个文件的传输进度。
本发明实施例中，重点描述了第一终端(即发送文件的终端)的处理过程，由于第二终端(即接收文件的终端)的处理过程与第一终端的处理过程相对应，在此不做赘述。
本发明实施例，第一终端接收到向第二终端传输文件的请求后，不是直接使用已经建立的一条通信连接或根据用户选择的一种通信方式建立的一条通信连接向第二终端传输文件，而是根据所述第一终端和所述第二终端共同支持的多种通信方式与所述第二终端建立多条第一通信连接，从而所述第一终端可以根据待传输的文件数量或文件大小通过所述多条第一通信连接中的至少一条通信连接向所述第二终端传输文件，由于建立多条通信连接的过程是终端自动实现的，无需用户手动操作，因此使用简单，并且可以使用多条通信连接协作传输文件或多条通信连接中传输质量较高的通信连接传输文件，因此传输效率高。
图3为本发明实施例提供的另一种传输文件的方法通信示意图，该实施例可以基于图1所示的应用场景，第一终端(例如终端103)和第二终端(例如终端104)均处于网络离线状态，即终端103和终端104之间不存在终端103通过服务器105到终端104的间接通信连接。该方法包括：
步骤301，第一终端进行传输文件准备，扫描本地所有可用的传输途径；第二终端进行传输文件准备，扫描本地所有可用的传输途径。
其中，步骤301可以由用户触发。触发步骤301的条件可以为第一终端接收到向第二终端传输文件的请求，以及第二终端接收到从第一终端传输文件的请求。

步骤310，多种途径进行文件传输。
其中步骤302，以及303、304、305、307、308协商的过程不一定是通过网络上直接连接的方式进行通信，也包括通过第三方服务器，比如即时通信(Instant Messaging，IM)系统的服务器。

步骤404，IM系统通知第一终端，第二终端在第一终端附近可以传输文件。
可以理解的是，步骤402至404为可选的发现终端的方式。

存储器140可用于存储软件程序以及模块，处理器130通过运行存储在存储器140的软件程序以及模块，从而执行手机100的各种功能应用以及数据处理。本发明中的要分享文件的应用，发送文件管理模块，以及传输的文件都存储在存储器140中。应用的运行、应用的处理逻辑都在处理器130上执行。
USB Driver 170，可提供其它终端设备与手机100的通信能力，比如从PC(个人电脑)上拷贝文件到手机100中，或者和另外一个手机通过OTG数据线传输文件等。可以理解的是，其并不属于手机100的必须构成，但是这种传输途径也是本发明涉及的一种。
GPS模块180，可提供定位能力，显示终端所处的经纬度，在一个示例中可以上传给IM系统作为两个终端是否在相近位置的判断。
其它无线传输模块190，包括蓝牙、NFC、Wifi模块等近距离传输模块。手机100通过其它无线传输模块190收发电子邮件、浏览网页和访问流式媒体等，它为用户提供了无线的宽带互联网访问，同时提供了和其它终端设备实现通信的能力，包括文件传输的能力。可以理解的是，其并不属于手机100的必须构成，手机可以具备其中的一种或者多种，也并不限于这几种，它们都属于本发明涉及的传输途径。

存储模块：是指手机上的存储文件的模块，比如内置SD卡，外置SD卡等。
本发明实施例中的文件传输管理模块用于终端之间分享文件，首先当终端A上的某个应用当需要应用内分享文件给其它终端的时候，会进行下面的步骤：
终端A上的应用通过拉起文件传输管理模块的界面(activity)，把要分享的文件列表(在存储模块中的位置)传递给它。
终端A的文件传输管理模块在收到发送文件的请求的时候，会检测本机所有可以用于传输文件的模块。让用户选择一种熟悉的方式进行连接，比如NFC。如图7中的(a)所示的终端A的用户界面示意图。
同时终端B用户可以点击接收文件按钮，同时也会自动自动扫描本机所有可以用于传输文件的模块。提示用户选择一种，比如NFC。如图7中的(b)所示的终端B的用户界面示意图。
当终端A和B都选择了NFC，并建立连接以后，开始后台的其它传输途径的协商，并创建连接。
整个协商过程如下：
连接上NFC以后，终端B首先响应终端A：本机支持的传输途径有：蓝牙、wifi直连、wlan、OTG数据线。
终端A返回消息，本机同样支持的传输途径有蓝牙、wifi直连、wlan。
终端B开启蓝牙。
终端B发送消息给终端A，消息中包括蓝牙的ID号。
终端A发送本机的蓝牙mac地址给终端B。终端A启动蓝牙，并主动根据终端B的蓝牙ID搜索信号，并尝试连接。
终端B的蓝牙在收到终端A的连接以后，会自动判断是否属于终端A的mac地址，如果是就自动接受连接。
在蓝牙连接成功后。终端A会发送连接成功的信息给终端B。蓝牙连接结束。
如果在20秒的时间内，没有完成蓝牙连接，终端A会发送蓝牙连接失败的信息给终端B。蓝牙连接结束。
终端B在蓝牙连接完成以后。开始准备进行下一个连接方式的连接，直到所有的连接创建。如图8所示为建立协商后的终端A和终端B的用户界面示意图。
在所有的连接过程结束后，终端B会向终端A发送可以开始发送文件的消息。
终端A会通过NFC，把要发送的文件列表发送给B。消息内容包括文件个数，每个文件的编号，文件大小，以及文件的md5。
假设有3个文件
文件1:0.5M
文件2:20M
文件3:5M
终端A会根据文件大小，对要发送的文件进行分割，并放入本地队列。
对于<2M的文件，当做一个发送任务
对于>2M的大文件，会被分割成2M一个的分片任务。
整个发送任务队列如图9所示。
终端A文件传输管理模块，会把发送任务会以抢占式的方式分配给不同的发送途径。如图10所示为终端A多途径并发发送文件示意图。
文件传输管理模块会不断的从待发送任务队列中获取发送任务，对应的从存储模块或得文件分片的数据流，把任务分配给已经连接的模块。
当其中一个模块发送完一个文件分片任务以后，文件传输管理模块会再等待传输队列再拉取一个任务分配给这个模块。
从而充分的利用所用的传输途径。并发的进行文件传输。
在终端B的文件传输管理模块，会接收不同传输途径发送过来的文件，因为多途径发送，终端B收到文件、以及文件分片没有先后顺序。如图11所示为终端B多途径并发接收文件示意图。
文件传输管理模块，在每接收完一个分片时，会校验分片的md5和大小，当一个文件的所有分片都传输完成的时候，会校验整个文件的大小以及md5。确保整个文件发送正确。
终端A和终端B都可以根据每个文件已经发送的的大小，在界面上显示多个文件的传输进度，如图12所示为本发明实施例提供的文件传输进度示意图。
本发明实施例，用户只要使用自己熟知的一种连接方式，把两个终端进行连接，连接后终端自己发现并创建其它连接方式，全面发挥终端的所有可以传输文件的器件能力。以达到快速传输文件的目的。用户只要知道其中一种传输途径的使用方式，进行连接后，程序就会自动协商创建其它传输途径的连接。该实施例使用队列，按文件数量、大小分割成多个小的发送任务，利用队列，在多传输途径上进行多路传输，充分利用了终端的能力，提高了传输效率。
图13为本发明实施例提供的另一种多途径传输文件示意图。终端通过IM系统发文件给好友或附近的人。
终端A和终端B，通过中间服务器进行传输途径的交互，如果终端A和终端B在都登录了某统一账户，在文件管理器中，当终端A用户点击了文件分享以后，会弹出终端A用户的好友列表，以及附近的用户。用户选择后，终端B用户会收到一个接收文件的通知。如果13所示，剩下的过程和图6所示的实施例类似。仅是在协商传输途径，以及传递文件列表的地方改成了通过第三方中间服务器。
本发明实施例，两个终端并不需要进行具体的传输连接，只要登录共同的IM系统，即可完成传输途径的协商，具体比如两个手机都登录了华为账号，都登录了QQ、微信等IM系统。让两个终端开始的连接更加便捷，不需要再去进行具体连接的配置。初次进行连接的方式可以是不能用于文件传输的方式，可以是两个终端都可以连接中间服务器，间接通过服务器进行传输途径的协商。
在一个示例中，可以进行传输途径优先级配置，比如GPRS传输优先级最低，以免产生流量费用。
在一个示例中，传输途径的概念可以用于更广范围的文件传输，比如通过百度网盘、亚马逊云等多个服务器的文件中转传输。
上述主要从方法流程的角度对本发明实施例的方案进行了介绍。可以理解的是，各个网元，例如终端等为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本发明能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本发明的范围。
