Description

Method for interconnecting mobile terminal and web terminal based on two-dimensional code and network adaptation

Technical field

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 to enable interactive communication.

Background technique

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, synchronize and interact with information between mobile devices and personal computers.

A conventional method of transferring files between a mobile electronic device and a personal computer, for example, uses a data cable to connect a personal computer to an electronic device, or a network transfer method such as a network disk. But these methods are very time consuming and 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 network transfer mode such as the network disk requires the user to be in an environment with a good network condition. If the network condition is poor and the file size that the user needs to transmit interactively is large, it is difficult to achieve a good transmission effect.

In addition, WiFi technology can provide transmission between mobile electronic devices and personal computers and higher transmission speeds. However, in the conventional scheme of implementing file transmission 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.

Short-range near-field communication technologies such as Bluetooth technology are now increasingly being used to transfer files between mobile electronic devices. However, Bluetooth technology typically does not provide high speed file transfers. In addition, personal computers are usually not equipped with Bluetooth modules, making bidirectional connection communication impossible.

Therefore, there is a need for an interconnection scheme that achieves a reliable, high speed, relatively long transmission distance between a mobile electronic device and a personal computer, thereby solving the above problems in the prior art.

Wireless communication methods such as WiFi or WLAN, GPRS, cellular networks, such as GSM networks, 3G networks, LTE networks, or CDMA networks.

A direct network connection can also be established between the mobile terminal 110 and the web terminal 120, and two-way communication is performed through the second network 150. The protocol mode adopted by the second network 150 is, for example, a manner in which http polling is combined with WebSocket direct connection.

The mobile terminal 110 can be a smart phone, a personal digital assistant (PDA), a tablet, a multi-function mobile terminal, or any other mobile device that includes computing functionality and data communication capabilities. The mobile terminal 110 includes an app interface application 111 (as shown in FIG. 1b), such as a custom application (app) for two-way communication with web-enabled applications.

The web terminal 120 can be any terminal device that supports a web protocol, such as a desktop computer, a laptop computer, a notebook computer, a tablet computer, a game console, a smart TV, and the like. The web terminal 120 includes a web interface 121 (shown in Figure 1b), such as a web browser. In some embodiments, the respective web terminal 120 includes a browser application for requesting, parsing, displaying, executing a web page, and executing an application included in the web page. Browser application 128 may be any application that allows a user to search, browse, and/or use resources (eg, web pages and web services) identified by a URL (Uniform Resource Locator) or URI (Uniform Resource Identifier). "URL" is used herein to mean the network address or location of a document. In this context, "document" refers to any document or content in any format that can be used by a web browser or other application, including but not limited to: word processing documents, spreadsheet documents, presentation documents, drawings, web pages, text, images. , audio, video, etc.

The output interface includes one or more of a display screen, one or more speakers, and a tactile interface.

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.

The two-dimensional code module 131 is configured to generate a two-dimensional code for scanning by the mobile terminal 110. According to 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.

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.

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.

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.

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 called "heart" The signal may 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 more than a certain number of times, the server side 130 can determine that the mobile terminal 110 or the web terminal 120 has disconnected from the server side 130.

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.

The address generation module 134 is configured to generate a file address that needs to be transferred between the mobile terminal 110 and the web terminal 120. 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.

interactive mode

2 shows a flow chart of a method for a user to interact with the web terminal 120 via the server terminal 130 via the mobile terminal 110. as shown in picture 2,

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.

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.

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.

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.

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, 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.

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.

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. 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 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.

Next, in step 250, the statistical information of the file to be synchronously transmitted by the mobile terminal 110 is sent to the server 130, and then the information is forwarded to the web terminal 120 via the server 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.

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 Figure 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 field 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 icon 305a in Figure 3b, 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.

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.

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.

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, the mobile terminal 110 or the web may be determined. 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.

File transfer method

4 shows a flow diagram of a method for a user to transfer files located on the mobile terminal 110 via the web terminal 120 via the server side 130. As shown in Figure 4,

At step 405, the user issues a request to transfer the file to the server 130 via the web terminal 120. According to an embodiment of the present invention, the user may first select the category in which the file type to be transferred is located. For example, "photo", "picture", "music", "video" or "document" and so on.

At step 410, based on the user's selection request, the server side 130 requests the mobile terminal 110 for summary information for all files in the selected category, including but not limited to file thumbnails, file information, file screenshots, and the like. The summary information of the acquired file category is then sent to the web terminal 120 in step 415. Preferably, the summary information of all files in the selected category is transmitted in a compressed or encrypted manner.

According to an embodiment of the present invention, when the user first requests a category of a certain transmission file, the server side 130 requests the mobile terminal 110 for summary information of all files in the selected category. These summary information can then be cached in the web terminal 120, such as in the browser cache of the web terminal 120. When the user selects the category again, there is no need to transfer from the mobile terminal 110 again, but directly from the cache until the web terminal 120 and the mobile terminal 110 are disconnected. According to an embodiment of the present invention, when the web terminal 120 and the mobile terminal 110 are disconnected, the cached file summary information is cleared.

Figures 5a and 5b schematically illustrate an exemplary file summary interface, respectively, in accordance with one embodiment of the present invention. Figure 5a shows the file summary information of the music file, and Figure 5b shows the file summary information of the video file. As shown in FIG. 5a, when the file category selected by the user at the web terminal 120 is "music", the server side 130 requests the mobile terminal 110 for summary information of all files in the selected category, the summary information including the name of the file, music. Duration, music file type, creation time, and more. As shown in FIG. 5b, when the file category selected by the user at the web terminal 120 is "video", the server side 130 requests the mobile terminal 110 for summary information of all files in the selected category, the summary information including the name and video of the file. A screenshot of a frame in .

Returning to Figure 4, in step 420, the user selects a file that he wants to download, to the server. End 130 sends a request to transmit the file.

Next at step 425, the server side 130 queries the network status identifier to establish a connection between the mobile terminal 110 and the web terminal 120 based on the identification of the network status identifier. Specifically, when the network status identifier identifies that the web terminal 120 and the mobile terminal 110 are under different networks, the file may be transferred by the relay of the server end 130, and the steps 430a-445a are performed. At step 430a, the web upload service is turned on at the server side 130. In step 435a, the file to be transferred on the mobile terminal 110 is uploaded to the server side 130, and the address (url) of the file is generated on the server side 130. Preferably, the file to be transferred on the mobile terminal 110 can be transferred in blocks, and each time a file segment is transmitted, the file address of the corresponding file segment is generated. In step 440a, the generated file address is sent to the web terminal 120. Preferably, when the files transmitted by the mobile terminal 110 are transmitted in chunks, the address of each file fragment is sent to the web terminal 120 by this. At step 445a, web terminal 120 accesses the received address and downloads the file.

When the network status identifier identifies that the web terminal 120 and the mobile terminal 110 are in the same network, the file can be transferred by establishing a direct connection between the web terminal 120 and the mobile terminal 110, and proceeds to steps 430b-440b. The direct connection avoids the relay of the server side 130, improving the transmission speed and transmission efficiency. In the case of direct connection, in step 430b, the mobile terminal 110 automatically launches a web service that generates a file address (url) for the file requested by the web terminal 120. In step 435b, the file address is sent to the web terminal 120. Next in step 440b, the web terminal 120 accesses the address to download the requested file.

FIG. 6 shows a flow chart of a method for a user to transfer a file to a mobile terminal 110 via a server terminal 130 via a web terminal 120. As shown in Figure 6,

At step 605, the user issues a request to transfer the file to the server 130 via the web terminal 120. According to an embodiment of the present invention, the user may first select the category in which the file type to be transferred is located. For example, "photo", "picture", "music", "video" or "document" and so on.

At step 610, based on the user's selection request, the server side 130 requests the mobile terminal 110 for summary information for all files in the selected category, including but not limited to file thumbnails, file information, file screenshots, and the like. The summary information of the acquired file category is then sent to the web terminal 120 in step 615. Preferably, the summary information of all files in the selected category is transmitted in a compressed or encrypted manner.

According to an embodiment of the present invention, when a user first requests a category of a transfer file At the time, the server 130 requests the mobile terminal 110 for summary information of all files in the selected category. These summary information can then be cached in the web terminal 120, such as in the browser cache of the web terminal 120. When the user selects the category again, there is no need to transfer from the mobile terminal 110 again, but directly from the cache until the web terminal 120 and the mobile terminal 110 are disconnected. When the web terminal 120 and the mobile terminal 110 are disconnected, the cached file summary information is cleared.

At step 620, the user selects a file that is intended to be transmitted to the mobile terminal 110 and sends a request to the server 130 to transfer the file. According to one embodiment of the invention, transferring files to the mobile terminal 110 can take a variety of approaches. One way is shown in Figures 5a and 5b. As shown in Figures 5a and 5b, the user can select a file to be transferred to the mobile terminal 110 by clicking the "Add Music" button 501 or the "Add Computer Video" button 502 in the upper left corner. Alternatively, the transfer of the file to the mobile terminal 110 can also be triggered by directly dragging the file under the item page of the corresponding type.

Next at step 625, the server side 130 queries the network status identifier to establish a connection between the mobile terminal 110 and the web terminal 120 based on the identification of the network status identifier. Specifically, when the network status identifier identifies that the web terminal 120 and the mobile terminal 110 are under different networks, the file may be transferred by the relay of the server end 130, and the process proceeds to steps 630a-645a. At this time, in step 630a, the web upload service is started on the server side 130. At step 635a, the address of the web upload service is sent to the web terminal 120. In step 640a, the web terminal 120 uploads the file to be transmitted to the server 130 first, and then forwards the uploaded file to the mobile terminal 110 through the server 130 in step 645a. Preferably, the files to be transferred on the web terminal 120 may be transferred in blocks, and each time a file segment is transmitted, that is, the web file upload address of the corresponding file segment is generated on the server side 130.

When the network status identifier identifies that the web terminal 120 and the mobile terminal 110 are in the same network, the file can be transferred by establishing a direct connection between the web terminal 120 and the mobile terminal 110, and proceeds to steps 630b-640b. The direct connection avoids the relay of the server side 130, improves the transmission speed and transmission efficiency, and saves network resources. In the case of direct connection, in step 630b, the mobile terminal 120 automatically launches a web upload service to generate a file upload address (url) for the requested file. In step 635b, the generated file upload address is sent to the web terminal 110. In step 640b, the web terminal 120 accesses the web upload address to upload the requested file.
