Description

用于在移动设备和web终端之间进行同步显示的方法Method for synchronous display between a mobile device and a web terminal

技术领域Technical field

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同步显示的方法和***。The present invention generally relates to the field of mobile communications, and in particular, to a method and system for interconnecting between a mobile terminal and a web terminal and for enabling simultaneous display therebetween.

背景技术Background technique

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、同步显示和交互。Currently, mobile electronic devices such as mobile phones, tablets, and mobile media players have become increasingly popular in people's daily lives. Mobile devices have gradually replaced traditional PCs and become the storage center for personal information. However, personal computers still have an irreplaceable role in many applications, with their large display screens, convenient input methods, and a wider variety of software and operating systems. Therefore, in daily life, people often need to transfer information, synchronize display and interaction between mobile devices and personal computers.

传统的在移动电子设备和个人电脑之间同步显示的方法例如使用数据线、视频/音频线等将个人电脑与电子设备连接，并通过运行特定的软件来实现。但这些方法是非常麻烦的，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。数据线的连接还会对设备的硬件接口有特殊的要求，例如常用的HDMI接口，只在比较新的电脑设备上才进行配置，稍微陈旧的型号均没有配置，使得连接无法实现。A conventional method of synchronizing display between a mobile electronic device and a personal computer, for example, connects a personal computer to an electronic device using a data line, a video/audio line, etc., and is implemented by running specific software. But these methods are very cumbersome and the user experience is very bad. For example, the way of the data line makes the user need to prepare additional hardware, which is inconvenient for the user. In addition, many additional drivers are required to implement more complex functions than transferring files. The connection of the data cable also has special requirements for the hardware interface of the device. For example, the commonly used HDMI interface is only configured on a relatively new computer device, and the slightly old model is not configured, so that the connection cannot be realized.

此外，WiFi技术可以提供移动电子设备和个人电脑之间的同步显示和传输。然而，在以往常规的用WiFi技术实现同步显示的方案中，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。In addition, WiFi technology provides simultaneous display and transmission between mobile electronic devices and personal computers. However, in the conventional conventional scheme of implementing synchronous display using WiFi technology, an access point (AP) is usually required. The access point acts as a wireless network relay between the mobile electronic device and the personal computer, and the personal computer and the mobile device must be connected to the wireless network relay at the same time to achieve interconnection. In a network dominated by APs, if the AP is disconnected, it will destroy the entire network and also damage the connection between the mobile device and the personal computer.

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数据从而实现同步的显示。然而，蓝牙技术通常无法提供高速的数据传输速度。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。Short-range near-field communication technologies such as Bluetooth technology are now increasingly being used to transfer data between mobile electronic devices for synchronized display. However, Bluetooth technology often does not provide high speed data transfer speeds. In addition, personal computers are usually not equipped with Bluetooth modules. Blocks, making bidirectional connection communication impossible.

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展示或观看手机上的内容，例如手机上存储的照片等。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同步显示这些文件，也是本领域亟待解决的一个问题。In addition, due to the versatility and portability of smartphones, users often take photos, record music, videos, etc. through their smartphones, which are limited by the smaller screen of the smartphone, and users often need to be on a personal computer or other large-screen display. Show or watch content on your phone, such as photos stored on your phone. Therefore, how to stably and simultaneously display these files on the basis of the interconnection of mobile electronic devices and personal computers is also an urgent problem to be solved in the art.

因此，需要一种在移动电子设备和个人电脑之间实现可靠、高速的同步显示方案，从而解决现有技术中的上述问题。Therefore, there is a need for a reliable, high speed synchronous display scheme between a mobile electronic device and a personal computer to solve the above problems in the prior art.

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和地址生成模块134。Figure 1b shows a system block diagram containing the specific architecture and composition of the server side. As shown in FIG. 1b, the server side 130 includes a two-dimensional code module 131, a network access module 132, a network status identifier 133, and an address generation module 134.

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)。The two-dimensional code module 131 is configured to generate a two-dimensional code for scanning by the mobile terminal 110. According to this issue In one embodiment of the invention, the two-dimensional code contains a Universally Unique Identifier (UUID), which is a unique identification code. The mobile terminal 110 connects to the server side 130 by scanning the UUID of the two-dimensional code table to request acquisition of a unique connection address and 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。The network access module 132 is configured to determine the network connection status of the mobile terminal 110 and the web terminal 120 after the corresponding mobile terminal 110 scans the two-dimensional code, so as to perform appropriate connection between the mobile terminal 110 and the web terminal 120 for different network connection conditions. The connections are made to establish a connection between the mobile terminal 110 and the web terminal 120. Preferably, the established connection is an http long connection. The connection can continuously send multiple data packets. If there is no data packet transmission during the connection hold period, in order to ensure that the two terminals remain connected, the detection data packet (ie, heartbeat packet) is sent within a predetermined interval, the mobile terminal 110 and the web. A detection packet needs to be sent between the terminals 120 to maintain the connection.

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。Specifically, the network access module 132 obtains the network status that the mobile terminal 110 and the web terminal 120 are respectively connected to the server end 130, and determines whether the network connection of the mobile terminal 110 and the web terminal 120 are under the same network. The same network according to the present invention means that the same network segment can be directly connected under the same router without going through the external network.

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。The network status indicator 133 is set to a different state depending on whether it is in the same local area network. For example, if it is in the same network, an identifier, such as the number 1, is set in the network status indicator 133; if not in the same network, the identifier is not set in the network status indicator 133, or another different identifier is set, for example The number is 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。According to an embodiment of the present invention, the network access module 132 periodically acquires the network status of each of the mobile terminal 110 and the web terminal 120 connected to the server to determine whether the network connection of the mobile terminal 110 and the web terminal 120 is under the same local area network. Whether the status changes and updates the network status indicator 133 for the changed network status. The frequency of the periodic acquisition may be, for example, once every 30 seconds. The periodically transmitted signal is also referred to as a "heartbeat signal" and can also be used to detect whether the mobile terminal 110 and the web terminal 120 are still connected to the server side 130. For example, when the heartbeat response signal fed back by the mobile terminal 110 or the web terminal 120 is not received for a certain number of times, the server 130 can determine that the mobile terminal 110 or the web terminal 120 has disconnected from the server end 130.

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。The network status indicator 133 is used to store an identification of the adaptive connection between the mobile terminal 110 and the web terminal 120 due to different network connection conditions. For example, the mobile terminal 110 and the web terminal 120 are in the same network, and an identifier is set in the network status identifier 133; if not in the same network, another different identifier is set.

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。An address generation module 134, configured to generate at the mobile terminal 110 and the web terminal 120 The file address transferred between. After the connection is established between the mobile terminal 110 and the web terminal 120 in accordance with the method of the present invention, the user may select to upload a file to the web terminal 120 via the mobile terminal 110 or download the file from the web terminal 120 to the mobile terminal 110. When the user issues such a request to move the file, the address generation module 134 generates a network-based address, such as a URL, for the transmitted file, to the mobile terminal 110 or web terminal 120 that needs to download the file, the mobile terminal 110 and the web terminal 120. Simply access the address to download the file to transfer the file.

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。At step 205, the user sends a connection request to the server side 130 via the web terminal 120. Specifically, the user can send a connection request by launching a browser on the web terminal 120 and entering address information of www.****.cc in the browser address bar.

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)。Next, in step 210, the server 130 sends the QR code information to the web terminal 120 in response to the connection request sent by the web terminal 120, and presents the two-dimensional code information on the web terminal 120 in step 220. The two-dimensional code information includes a universal unique identification code (UUID), and the UUID is a unique identification code. The mobile terminal 110 connects to the server side 130 by scanning the UUID of the two-dimensional code table to request acquisition of a unique connection address and 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。Next, at step 225, the user scans the two-dimensional code information on the web terminal 120 through the mobile terminal 110. For example, scanning is performed by a camera carried on the mobile terminal 110. Specifically, the user activates the app software on the mobile terminal 110, and the app software prompts the user to scan the two-dimensional code to implement the connection.

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。Next, in response to the user's operation of scanning the two-dimensional code, the mobile terminal 110 and the web terminal 120 initiate a connection request to the server side in steps 230a and 230b, respectively, and transmit their own network connection status to the server side 130. Specifically, the network connection status is a network connection to the server end.

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。In step 235, the server side 130 determines whether the network connection of the mobile terminal 110 and the web terminal 120 is under the same local area network by acquiring the network status of the mobile terminal 110 and the web terminal 120 respectively connected to the server, and whether the network connection is in the same local area network. The network status indicator sets a different status. For example, if it is in the same network, an identifier is set in the network status indicator 133, such as the number 1; if not in the same network, it is not An identifier is set in the network status indicator 133, or another different identifier is set, such as the number 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。Next, the server side 130 transmits a connection establishment permission to the mobile terminal 110 and the web terminal 120 in steps 240a and 240b, respectively, thereby establishing a connection between the mobile terminal 110 and the web terminal 120. Preferably, a http long connection is established.

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。Next, at step 245, the connected interface is presented at the mobile terminal 110. FIG. 3a schematically illustrates a connection interface of an exemplary mobile terminal 110 in accordance with one embodiment of the present invention. As shown in FIG. 3a, the presentation interface of the mobile terminal 110 is divided into an item column 301 located at the top of the interface and a file example column 302 located below the item column 301. In the item column 301, files that can be synchronously transferred are schematically classified into items such as "photograph", "gallery", "music", "video", "document", and the like, and the user can switch between different items.

Under each selected item, the files belonging to the item will be displayed according to different sorting methods such as time and file size, preferably by thumbnail, file name, file icon, and the like.

根据本发明的一个实施例，在步骤245之后还可以进一步显示更多的移动终端110和web终端120之间的同步信息。如图2所示，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。According to an embodiment of the present invention, more synchronization information between the mobile terminal 110 and the web terminal 120 may be further displayed after step 245. As shown in FIG. 2, in step 250, the statistical information of the file to be synchronously transmitted by the mobile terminal 110 is transmitted to the server side 130, and then the information is forwarded to the web terminal 120 via the server side 130 in step 255. Preferably, the synchronization statistics information includes the number of files to be transferred by the synchronous connection, the file type, and the number of files of each category. Some basic information of the mobile terminal 110, such as an operating system model, mobile phone user basic information, a version model, and the like, may also be included.

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。Next, at step 260, the connected interface is presented at the web terminal 120, and the synchronization statistics forwarded by the server 130 are simultaneously presented. FIG. 3b schematically illustrates a connection presentation interface of an exemplary web terminal 120 in accordance with one embodiment of the present invention. As shown in FIG. 3b, in the presentation interface of the web terminal 120, the navigation bar 303 located on the left side of the interface and the file statistics column 304 located on the right side of the navigation bar 303 are divided. In the navigation bar 303, files that can be synchronously transmitted are schematically classified into "photograph", "gallery", "music", "video", "document", "sms", "folder", "application", and the like. Project, users can switch between different projects. You can also add a Home page item to view overall file statistics. Those skilled in the art can understand that the above items are merely exemplary, and new items can be added or reduced according to different needs. Under the "Home" item, the number of various files is displayed in the file statistics column 304 according to the type of the file. For example, the exemplary music map in Figure 3b Mark 305a, and the number of music (39) icons 305b below it. In addition, some basic information of the transmitted mobile terminal 110, such as the storage capacity information of the mobile terminal 110 presented at 306 below in the file statistics column 304, may also be presented to facilitate the user managing the mobile terminal 110 through the web terminal 120.

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。When the user needs to disconnect the web terminal 120 and the mobile terminal 110, the disconnection can be achieved by closing the web interface of the web terminal 120 (e.g., a browser) or by closing either or both of the app.

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。According to another embodiment of the present invention, when the user does not actively disconnect, or the user disconnects the network connection of any of the mobile terminal 110 or the web terminal 120, the server 130 may also pass to the mobile terminal 110 and the web terminal. 120 sends a heartbeat signal to verify if the connection is still maintained. For example, when the heartbeat response signal fed back by the mobile terminal 110 or the web terminal 120 is not received for a certain number of times, the server 130 can determine that the mobile terminal 110 or the web terminal 120 has disconnected from the server end 130. The server side 130 can then disconnect the connection between the mobile terminal 110 and the web terminal 120. Specifically, when the server 130 determines that the mobile terminal 110 or the web terminal 120 has disconnected from the server 130, the server 130 sends a command to the web terminal 120, and the web terminal 120 returns to the initial unconnected state, for example, The page state of the QR code. The server side 130 also simultaneously sends a command to the mobile terminal 110 such that the mobile terminal 110 also returns to the initially unconnected state. That is, when the server side 130 detects that any one of the mobile terminal 110 or the web terminal 120 is disconnected, the other party is immediately disconnected at the same time to ensure the security of the information.

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。According to an embodiment of the present invention, when the mobile terminal 110 or the web terminal 120 is connected to the server side 130 in a mobile network manner (for example, GPRS, 3G, 4G, etc.), the server end 120 can simultaneously detect the mobile terminal when detecting the heartbeat signal. 110 or mobile network cell condition in which web terminal 120 is located. When the cell connected by any one of the mobile terminal 110 or the web terminal 120 is switched, it can be determined that the mobile terminal 110 or the web terminal 120 has left the other party for a physical distance. In order to ensure the security of file transfer, it may be set to disconnect the connection between the mobile terminal 110 and the web terminal 120 after leaving a certain distance.

同步显示方式Synchronous display mode

图4示出了在web终端120和移动终端110之间进行同步显示的方法流程图。如图4所示，FIG. 4 shows a flow chart of a method for synchronous display between web terminal 120 and mobile terminal 110. As shown in Figure 4,

在步骤405，用户通过web终端120向服务器端130发出请求同步显示的请求。根据本发明的一个实施例，用户可以通过点击web终端120上的任意按钮来触发这一操作请求。例如，点击图3b中的“开始”按钮306。At step 405, the user sends a request to the server 130 via the web terminal 120. The step shows the request. According to one embodiment of the invention, the user can trigger this operational request by clicking on any button on the web terminal 120. For example, click on the "Start" button 306 in Figure 3b.

在步骤410，基于用户发出的请求，服务器端130向移动终端110转发该同步显示的请求。At step 410, based on the request issued by the user, the server 130 forwards the request for synchronization display to the mobile terminal 110.

在步骤415，移动终端110收到该请求，触发生成长连接地址。优选地，该长连接为http长连接。At step 415, the mobile terminal 110 receives the request and triggers the generation of a long connection address. Preferably, the long connection is a http long connection.

在步骤420，移动终端415将该长连接地址发送给web终端120。根据本发明的一个实施例，该长连接地址可以通过服务器端130进行中转后发送给web终端120。At step 420, the mobile terminal 415 sends the long connection address to the web terminal 120. According to an embodiment of the present invention, the long connection address may be transited by the server 130 and sent to the web terminal 120.

在步骤425，web终端120向移动终端110发送建立长连接的应答确认，从而在web终端120建立了与移动终端110之间的长连接。即，web终端120可以定期访问该长连接地址从而保持与移动终端110的连接。根据本发明的一个实施例，该应答确认可以通过服务器端130进行中转后发送给移动终端110。At step 425, the web terminal 120 sends a response confirmation to the mobile terminal 110 establishing a long connection, thereby establishing a long connection with the mobile terminal 110 at the web terminal 120. That is, the web terminal 120 can periodically access the long connection address to maintain the connection with the mobile terminal 110. According to an embodiment of the present invention, the response confirmation may be transmitted to the mobile terminal 110 after being relayed by the server 130.

在步骤430，移动终端120在收到应答确认后，触发开始按特定的时间间隔进行截屏操作。所述截屏操作即截取移动终端120上运行的当前应用所显示的图像。根据本发明的一个实施例，可以任意设定该时间间隔，例如每1/10-1/2秒截取屏幕一次。优选地，每1/4秒截取屏幕一次。截屏的时间间隔也可以根据网络状况来设定，例如在网络状况良好的情况下，缩短相邻两次截屏之间间隔的时间。At step 430, after receiving the response confirmation, the mobile terminal 120 triggers the start of the screen capture operation at a specific time interval. The screen capture operation intercepts an image displayed by the current application running on the mobile terminal 120. According to an embodiment of the present invention, the time interval can be arbitrarily set, for example, the screen is intercepted once every 1/10-1/2 second. Preferably, the screen is intercepted once every 1/4 second. The time interval of the screen shot can also be set according to the network condition, for example, when the network condition is good, the time between the adjacent two screen shots is shortened.

步骤435，移动终端110将截屏图像按截取的时间顺序依次发送给web终端120。Step 435, the mobile terminal 110 sequentially sends the screen capture images to the web terminal 120 in the time sequence of interception.

步骤440，web终端120按接收到的时间顺序依次显示所接收到的截屏图像。In step 440, the web terminal 120 sequentially displays the received screenshot images in the received chronological order.

根据本发明的一个实施例，移动终端110可以将截取的屏幕图像以“先进先出”的队列方式进行存储，再按照特定的时间间隔从队列中取出队列中的截屏图像，发送给web终端120。优选地，从队列中取截屏图像的时间间隔可以等于步骤430中截屏操作的时间间隔。According to an embodiment of the present invention, the mobile terminal 110 may store the intercepted screen image in a "first in, first out" queue manner, and then take out the screen capture image in the queue from the queue according to a specific time interval, and send it to the web terminal 120. . Preferably, the time interval for taking a screen shot image from the queue may be equal to the time interval of the screen capture operation in step 430.

根据本发明的另一实施例，移动终端110可以不存储截取的屏幕图像，而是每截取一张即刻发送一张给web终端120。这种方式对移动终端110和web终端120之间连接网络质量，特别是掉线率的要求较上一种实施方式更高。 According to another embodiment of the present invention, the mobile terminal 110 may not store the intercepted screen image, but send one piece to the web terminal 120 every time one is intercepted. In this way, the connection quality between the mobile terminal 110 and the web terminal 120, especially the drop rate, is higher than that of the previous embodiment.

根据本发明的另一实施例，web终端120可以以访问移动终端110长连接地址的方式来获取截屏图像。具体地，移动终端110可以将所截取屏幕的地址信息发送给web终端120，web终端120访问该地址，下载所需的截屏图像。According to another embodiment of the present invention, the web terminal 120 may acquire a screen shot image in a manner of accessing the long connection address of the mobile terminal 110. Specifically, the mobile terminal 110 may transmit the address information of the intercepted screen to the web terminal 120, and the web terminal 120 accesses the address to download the required screenshot image.

根据本发明的另一实施例，截屏图像的传输也可以经过服务器端130的中转来进行。具体地，移动终端110可以将截屏图像先传输至服务器端130为其开辟的存储区域中，然后服务器端130再将截屏图像按照收到的顺序依次发送给web终端120。或者，服务器端130也可以中转截屏图像的存储地址给web终端120，web终端120再按照该地址访问去下载所需的截屏图像。According to another embodiment of the present invention, the transmission of the screen shot image may also be performed by the relay of the server side 130. Specifically, the mobile terminal 110 may first transmit the screen capture image to the storage area opened by the server end 130, and then the server side 130 may sequentially send the screen capture image to the web terminal 120 in the received order. Alternatively, the server 130 can also transfer the storage address of the screenshot image to the web terminal 120, and the web terminal 120 can access the screen capture image according to the address.

根据本发明的另一实施例，web终端120也可以开辟存储收到的截屏对象的队列，以“先进先出”的方式从队列中依次弹出截屏图像，进行显示。According to another embodiment of the present invention, the web terminal 120 may also open a queue for storing the received screen capture object, and pop-up the screen capture images from the queue in a "first in, first out" manner for display.

图5a-图5c分别示意性地示出了根据图4的方法在web终端120上显示的示例性截屏图像。其中图5a显示的是当用户选择“图库”项目时呈现的屏幕显示，图5b显示的是当用户在移动终端110通过向左滑动屏幕向“音乐”项目切换时呈现的屏幕显示，图5c显示的是用户切换到“音乐”项目时呈现的屏幕显示。根据图4中描述的方法，由于本发明设定的特定截屏和显示时间间隔，因此在web终端120显示时，用户可以体验连贯的显示效果。即使是用户在切换屏幕的过程中呈现的中间效果(如图5b)，也将通过截屏传输的方式完整地呈现在web终端120。因此，呈现的效果就像是用户通过移动终端110来直接操作web终端120一样。5a-5c schematically illustrate exemplary screen shot images displayed on web terminal 120 in accordance with the method of FIG. 4, respectively. Figure 5a shows the screen display presented when the user selects the "Gallery" item, and Figure 5b shows the screen display that is presented when the user switches to the "Music" item by swiping the screen to the left, Figure 5c shows Is the screen display that is presented when the user switches to the Music item. According to the method described in FIG. 4, due to the specific screen shot and display time interval set by the present invention, the user can experience a coherent display effect when the web terminal 120 is displayed. Even the intermediate effect presented by the user during the process of switching screens (as in Figure 5b) will be fully presented to the web terminal 120 by means of screencast transmission. Therefore, the effect of presentation is as if the user directly operated the web terminal 120 through the mobile terminal 110.

根据本发明的方法和***，用户可以在移动电子设备和具备web接口的web终端之间实现可靠、高速、稳定、用户交互体验更好的同步显示方案。According to the method and system of the present invention, a user can implement a synchronous, high-speed, stable, and user-friendly interactive display scheme between the mobile electronic device and the web terminal having the web interface.
