Systems and methods for sharing resources

technical field

The present invention relates to the field of communication technology, in particular to a system and method for realizing resource sharing through a communication-capable terminal.

Background technique

The typical method of long-distance transmission of data files between existing mobile terminals is to send multimedia messages. The mobile terminal of the information sender sends the multimedia message to the operator's server. After receiving the multimedia message, the operator's server forwards it to the information receiver. After receiving the multimedia message, the mobile terminal of the information receiver accesses the information via WAP, and directly downloads resources from the operator's server. At the same time, use the original data line or use WIFI to share files between the mobile terminal and the personal computer. Wherein, the transmitted data files include text, documents, pictures, and may also be video and audio files composed of streaming media files.

The existing mobile communication system is based on the traditional C/S architecture, and users need to upload files to the network server. If the file is large, it takes a long time to upload and download the file. However, file sharing via WIFI cannot solve the problem of long-distance transmission.

Detailed ways

In order to realize the remote sharing of resources in the mobile terminal, the present invention provides a central server and a shared resource server. The shared resource server may be a mobile terminal or a personal computer that provides the service, and the shared resource server may also be set in the mobile terminal or the personal computer that provides the shared service. When the shared resource server initiates sharing, it is necessary to log in to the central server and maintain a connection with the central server. For example, when the shared resource server initiates sharing for the first time, it can register a user name and password with the central server, and when sharing again, it can input the user name and password to the central server to log in to the central server to connect with the central server.

The function of the shared resource server is mainly to provide shared resources, which include various files and/or folders including various files, automatically generate a shared resource description file (share_description_file) of the shared resource and upload the shared resource description file to A central server, so that users at the sharing resource requesting end (that is, terminals that request the sharing resource from the central server) can access the sharing resource conveniently and efficiently. It should be understood that the shared resource requesting end may be a mobile terminal or a personal computer. There are two main functions of the central server, one is resource location, and the other is protocol proxy. Resource location means that when a shared resource requester searches for a shared resource server by domain name, the central server will correctly locate the shared resource server that initiated the sharing through the secondary domain name in the Uniform Resource Locator (URL). The protocol proxy is to convert the HTTP protocol of the shared resource request end into the communication protocol between the central server and the shared resource server. The shared resource requester can view the shared files or folders through a browser so as to download the files or folders.

FIG. 1 is a block diagram of a structure of a shared resource server provided in a terminal providing a shared service according to an exemplary embodiment of the present invention. The shared resource server includes a server registration module 110 , a shared resource controller 120 , a transmission shared resource server module 130 and a shared resource management module 140 .

When the user starts the shared resource server to publish the shared resource, the server registration module 110 registers with the central server by transmitting the shared resource server module 130 . That is, register the account and password for the shared resource service; when the registration is successful, the central server keeps connected with the transmission shared resource server module 130 .

The shared resource controller 120 provides a user interface for users to select/close shared resources. After the user selects the resource that needs to be shared/closed on the user interface, the shared resource management module 140 manages all local shared resources, and generates a corresponding shared resource description file, and transmits the shared resource server module 130 in the shared resource controller 120. The shared resource description file is sent to the central server under control. The transmission shared resource server module 130 provides connection between the shared resource server module and the central server, command transmission between the central server and the shared resource server, and transmission of shared resources.

Here, a shared resource server is set in the terminal providing the shared resource, and a central server is set in the public network. If the terminal user wants to use this system to initiate sharing, the server registration module 110 in the terminal will register with the central server for the shared resource service account number. When a terminal user needs to share resources with other users, firstly, under the control of the shared resource controller 120, the terminal user connects to the central server through the transmission shared resource server module 130, that is, logs in to the central server. If the login is successful, the terminal remains connected to the central server, and the central server will assign a second-level domain name under the central server domain name to the logged-in terminal. The difference between the resource sharing system described here and the traditional sharing method is that remote sharing can be realized, and the terminal requesting shared resources does not need to install additional software, and only needs a browser to access the shared resources on the terminal, so requesting shared resources The range of terminals is greatly increased.

For example, when another user B wants to read the shared resources in terminal A, he only needs to enter the address http://a-name.center-server-domain in the browser of the terminal held by the user B, and the The shared resources provided by Terminal A can be seen on the web page and can be downloaded. In the above URL, a-name represents the account name registered by the user of terminal A on the central server. Here, the name can be used as the secondary domain name corresponding to the terminal A under the central server domain name; center-server-domain represents the central The domain name of the server. In this way, the user can share the resources in terminal A to any remote terminal with a browser.

Among them, after the shared resource server logs into the central server, the central server will save the mapping relationship between the connection ID with the shared resource server and the second-level domain name assigned to the shared resource server in the database, and the shared resource server will also save the The information of the resource to be shared forms a shared resource description file, and sends the shared resource description file to the central server. When the shared resource requester connects to the central server through a browser, the central server will determine the shared resource according to the second-level domain name. Which resource on the shared resource server is requested by the resource requester, the central server will generate an HTML file according to the corresponding shared resource description file and return it to the shared resource requester, then the user of the shared resource requester will be on the browser See Shared Resource Server for a description of resources shared.

FIG. 2 shows only an example page of the shared file on the shared resource server seen by the shared resource requesting end through the browser. This page is dynamically generated by the central server by parsing the shared resource description file. What is shown in Figure 2 is just an example. The specific forms of this page can be various, as long as the shared file in the shared resource server That's it. As shown in Figure 2, it imitates the page form displayed by accessing the SVN server through a browser. As shown in Figure 2, the leftmost column in Figure 2 indicates the file name or folder name of the shared resource, while the middle column indicates the size (size) and type (type) of the file or folder, and the type can represent It is a file (file) and a folder (dir). Here, if the type is a file, it means that the corresponding shared resource is a file, and if the type is a folder, it means that the corresponding shared resource is a folder.

When the shared resource requester needs to download a shared file or folder, click the "Download" link on the page shown in Figure 2. When the central server receives the request, it forwards the request to Shared resource server, after receiving the request, the shared resource server sends the corresponding shared resource to the central server. After the central server receives the shared resource sent by the shared resource server, it returns the resource file to the shared resource requesting end through an HTTP response message.

Fig. 3 is a network structure diagram of shared resource transmission. In the case of remote sharing of resources, three types of network elements are defined, the central server, the shared resource server (the shared file user shown in Figure 3), and the shared resource requester (the resource consumer user shown in Figure 3) . In the process of completing the file transfer, the central server plays the role of resource positioning and protocol proxy. The so-called protocol proxy means that in the process of completing the shared resource transmission, one is to transfer the HTTP request between the shared resource request end and the central server. It is converted into a private protocol between the central server and the shared resource server, and the second is to convert the shared resource returned from the shared resource server to the central server through the private protocol to return to the shared resource request end through HTTP response. As shown in FIG. 3 , the remote transmission of shared resources from the shared resource server to the shared resource requesting end is completed through the proxy of the central server. Here, the central server is located in the public network, and the shared resource server is located in the private network, so the central server cannot proactively find the shared resource server, and the connection between the central server and the shared resource server requires the shared resource server to actively request to connect to the central server. Here, the connection protocol (that is, the private protocol) between the shared resource server and the central server is a simple socket connection, and the communication protocol after the connection is a custom command sent by using the socket. Due to network limitations, the control here is connected to the same Socket used by the resource bearer.

For example, but not as a limitation, after the shared resource server registers an account for shared resource services with the central server, it maintains a TCP/IP connection with the central server, publishes shared resource information and transmits shared resources. During the entire communication process, the defined The various commands described below can be extended if necessary:

(1) The shared resource server registers an account with the central server

REGISTER_COMMAND::="REGISTER:"user_id"#"password

(2) The central server requests resources from the shared resource server

GETFILE_COMMAND::="GETFILE:" file_id

(3) The shared resource server sends resources to the central server

SENDFILE_COMMAND::=“SENDFILE NAME:”file_name”\nSIZE:”file_size”\n CONTENT:”file_content

(4) The shared resource server publishes/updates the information of the shared resource to the central server

UPDATESHARE_COMNAND::=“UPDATESHARESIZE:”file_size”\ncontent:”file_content

(5) The shared resource server stops the service of the shared resource

STOP_COMMAND::="STOP"

(6) Reply with success message

SUCCESS_REPLY::="SUCCESS"

(7) Reply failure message

FAILED_REPLY::="ERROR: "error_code"\n".

Here, the shared resource server will monitor the status of the shared resource. When a resource update occurs, for example, when the content of the file is modified, the shared resource server will resend the update command to the central server: UPDATESHARE_COMNAND::=“UPDATESHARESIZE:”file_size”\ncontent :"file_content; if the file is deleted, the shared resource server sends a command to the central server: DELETESHARE_COMMAND::="DELETESHARE_ID:"file_id. In other words, when the state of the shared resource changes, the shared resource server will send an update command to the central server so that the central server can update the shared resource description file.

Fig. 4 is a signal flow diagram for implementing sharing of shared resources according to an exemplary embodiment of the present invention. When sharing resources, the shared resource server first logs in to the central server, so as to maintain the connection between the shared resource server and the central server. According to the present invention, the process of remote sharing of resources between terminals is as follows:

In step S410, user A activates the shared resource server on the terminal, and selects resources to be shared, that is, files and/or folders to be shared, and the shared resource server generates corresponding shared resource description files.

In step S420, the shared resource server on user A's terminal logs in to the central server to maintain a connection with the central server, and at the same time sends the shared resource description file to the central server. After the shared resource server logs in to the central server, the central server will assign a second-level domain name under the domain name of the central server to the logged-in terminal, and other users can use the second-level domain name to share the resources shared by user A’s shared resource server . The central server will save the mapping relationship between the connection ID with the shared resource server and the second-level domain name of the shared resource server assigned to user A in the database.

In step S430, the shared resource requester (ie, user B's terminal device) connects to the central server. For example, a shared resource requester can connect to a central server through a browser. For example, the shared resource requester enters the second-level domain name (for example, http://a-name.center-server-domain ) of user A's shared resource server in the browser to view the resources shared by user A's shared resource server.

In step S440, the central server generates a corresponding HTML page according to the shared resource description file and returns it to the shared resource requesting end. Wherein, the central server will determine which resource on the shared resource server the shared resource requester requests according to the second-level domain name input by the shared resource requester, so as to find the corresponding shared resource description file and generate a corresponding HTML page.

In step S450, the shared resource requester requests the desired shared resource by clicking on the link on the HTML page.

In step S460, after receiving the request for the shared resource, the central server forwards the request to the shared resource server.

In step S470, the shared resource server sends the requested shared resource to the central server after receiving the request.

In step S480, after receiving the shared resource, the central server forwards the shared resource to the shared resource requester by using an HTTP response message.

The exemplary embodiment of the present invention provides a method for remote resource sharing, which can conveniently access shared resources on various platforms without installing additional software at the sharing resource requesting end.

While the invention has been particularly shown and described with reference to embodiments thereof, it will be understood by those skilled in the art that changes may be made in form and detail without departing from the spirit and scope of the invention as defined by the claims. Various changes.
