Detailed Description

[0044] A detailed description of the technical solutions of the embodiments of the present disclosure is provided below in view of the accompanying drawings. It should be understood that the embodiments described below are representative embodiments of the present disclosure rather than a complete disclosure of the every possible embodiment. The present disclosure can also include any other embodiments that can be derived from these disclosed embodiments by a person with ordinary skill in the art without any additional inventive work. It is to be understood that other embodiments can be used and structural changes can be made without departing from the scope of the embodiments of this disclosure.

[0045] This disclosure generally relates to data sharing among multiple terminals using a communication application. As referred hereinafter, terminals can be any electronic device capable of communicating with one or more other terminals over a computer network, preferably, a wireless network, for transmitting and/or receiving data. Such devices can include, but are not limited to, PCs, Macs, desktop computers, laptop computers, tablet PCs, smartphones including iPhones, Android phones, Windows phones, and Blackberries, e-readers, in-car communication devices, televisions, gaming consoles and other consumer electronic devices with sufficient network capabilities. Furthermore, the terms "device" and "terminal" are interchangeable terminologies in this disclosure.

[0046] The terminals/devices in the embodiments discussed below can have installed on them and run a communication tool or application (the terms "tool" and "application" are interchangeable terminologies in this disclosure) for communicating with one or more other terminals/de vices. The communication tool or application can, for example, be an instant messaging application (e.g., MSN messenger by Microsoft or QQ by Tencent) or any other types of messaging applications. In the embodiments described below, a terminal or device can be referred to as a first instant messaging terminal or a second instant messaging terminal, although it should be understood that the first and second instant messaging terminals are not necessarily terminals dedicated for the purpose of sending and receiving instant messages or any other types of messages. That is, the first and second instant messaging terminals can be any devices such as those listed above. They can be general purpose devices (PCs, iPhones) or devices built for particular purposes, so long as they are capable of communicating with one or more other terminals via a communication application.

[0047] To share data, one of the terminals (e.g., the first instant messaging terminal) can log into an account of the communication application, such as an instant messaging application and send a data-sharing request to one or more other terminals (e.g., the second instant messaging terminal) requesting to share data one the one or more other terminals. The request and some, if not all, of the communications between the terminals can be through the communication application. The second instant messaging terminal (and/or other terminals) can also be logged into an account of the

communication application to receive the request and other communications from the first instant messaging terminal. In some embodiment, the accounts logged into by the requesting terminal (e.g., first instant messaging terminal) and the receiving terminal (e.g., second instant messaging terminal) can be the same account. For example, a user may have two devices (e.g., an iPhone and a MAC), both running an instant messaging application. The user can be logged into the same instant messaging account on both of these devices to share data on one of the devices with the other device. Alternatively, the terminals can log into different, but related accounts of the communication application. The related accounts can be accounts that are designed as "friends" with respect to each other or are members of the same public or private group. This allows friends and/or users in the same social group to share data from their respective devices using the methods, terminals, and systems disclosed herein. [0048] In the various embodiments discussed below. The same terminal can be both a terminal requesting data from another terminal and a terminal from which data can be requested. Data stored on a terminal can be referred to as one or more data resources. A data resource can include any type of data, such as image, text, audio, video, and any other multimedia data stored on a user device. The second instant messaging terminal, after receiving the data-sharing request, can send a reply back to the first instant messaging terminal either granting or denying the request. If the request is granted, the second instant messaging terminal can also send one or more IDs identifying one or more data resources on the second instant messaging terminal that are available for sharing. The IDs can be included in the reply and transmitted to the first instant messaging terminal via the communication application. The IDs of the available data resources can then be displayed on the first instant messaging terminal to allow the user to select the desirable data resource(s) to be obtained from the second instant messaging terminal. The first instant messaging terminal can then send a data-reading request including the selected data resource IDs to the second instant messaging terminal. Based on these IDs, the second instant messaging terminal can transmit the corresponding data resources to the first instant messaging terminal. The data-reading request and/or the corresponding data resources can also be transmitted via the communication application. Alternatively, the data resources can, for example, be transmitted via a different application. In some embodiments, the data can be automatically displayed using a suitable application on the first instant messaging terminal when it is received. For example, a data resource that is a video clip can be automatically played using a multimedia application on the terminal.

[0049] As described in the embodiments below, in operation, the terminals (e.g., the first and second instant messaging terminal) can be connected to each other via a network. The network can be any computer network such as the Internet, a LAN, wide area network (WAN), cellular network, Wi-Fi network, and virtual private network (VPN). Preferably, the connection can be wireless in some embodiments.

[0050] In some embodiments, the terminals can connect to each other directly and communicate with each other without going through a server. For example, when the terminals can connect to each other directly when they are connected to the same network, (e.g., the same LAN or Wi-Fi spot) or when they are connected directly to each other via, for example, a Bluetooth connection. If the terminals cannot connect to each other directly, they can communicate through a messaging server (e.g., an instant messaging server such as a QQ server provided by Tencent for supporting the QQ instant messaging application). For example, when the first and second instant messaging terminals are connected to two different networks (e.g., LANs) or direct communication is block by a firewall, some or all of the communications between the first and second instant messaging terminals can be routed through a messaging server. In some embodiments, to determine whether two or more terminals can connect to each other directly, each of the terminals can upload their gateway device information to a server, which can then determine, based on the gateway device information, whether the terminals can connect to each other directly.

[00511 In some embodiments, if the communication application is not in an active mode on a terminal (e.g., if the application is running in the background while another application is running in the foreground), the messaging server may first send a message (e.g., a push message) to the terminal to activate the communication application (e.g., move it to the foreground) before forwarding a data request to the terminal. This can request the messaging server to obtain an operating status of the communication application on the terminal before forwarding any communication to the terminal.

[0052] In the embodiments of the present disclosure, an instant messaging terminal can be a personal computer (PC), mobile phone, tablet PC, smartphone, e-reader, laptop computer, in-car terminal, or any other network-enabled device.

[0053] Fig. 1 is a flowchart illustrating the exemplary steps in a data-sharing method, according to a first embodiment of the disclosure. The data-sharing method in the illustrated embodiment can include the following steps.

[0054] S 101 : A first instant messaging terminal can transmit a data-sharing request to a second instant messaging terminal. The first instant messaging terminal and the second instant messaging terminal can interact with each other by logging into related accounts of an instant messaging application. In particular, in this embodiment, the first instant messaging terminal and the second instant messaging terminal can be two network devices on the same LAN. The terminals can discover each other as terminals logged into the related accounts on the LAN by having one of the terminals broadcasting a discovery message over the LAN. The related accounts can be friends with respect to each other or members of a particular group. They can also be the same instant messaging account logged in at different terminals.

[0055] SI 02: The second instant messaging terminal can respond to the data- sharing request, and transmit a reply permitting data sharing to the first instant messaging terminal. The reply permitting data sharing can include an ID collection of one or more shareable data resources. In particular, the second instant messaging terminal, after receiving the data-sharing request, can display a message prompting whether or not to grant the data-sharing request. It can respond to the data-sharing request based on a user input selection. If the user chooses to reject the request, the second instant messaging terminal can send a reply to the first instant messaging terminal rejecting the request and the process can end. If the user chooses to allow data sharing, the second instant messaging terminal can send a reply to the first instant messaging terminal granting the request. The reply granting data sharing can include an ID collection of one or more shareable data resources, which can include at least one data resource ID. The data resource ID can be an ID of a data resource at the second instant messaging terminal that can be shared with the first instant messaging terminal or any other terminals. The user can manually designate a data resource, a type of data resources, or a folder of data resources as shareable data resources. The second instant messaging terminal can generate a corresponding data resource ID of a shareable data resource. The data resource ID can be of a format including, for example, the name, abstract, attribute, or thumbnail associated with the data resource. The ID collection of the one or more shareable data resources can include a list including multiple data resource IDs.

[0056] SI 03: The first instant messaging terminal can transmit a data-reading request to the second instant messaging terminal. The data-reading request can include at least one data resource ID. In particular, after the first instant messaging terminal receives the reply from the second instant messaging terminal, the first instant messaging terminal can display the ID collection of the one or more shareable data resources in the reply to prompt a user at the first instant messaging terminal to select one or more desirable data resources to be obtained. After receiving a selection command from the user, the first instant messaging terminal can transmit a data-reading request to the second instant messaging terminal. The data-reading request can include at least one data resource ID.

[0057] S I 04: The second instant messaging terminal can transmit to the first instant messaging terminal one or more data resources corresponding to the one or more data resource IDs in the data-reading request. This can allow the first instant messaging terminal to obtain data via an instant messaging application from the second instant messaging terminal logged into a related account.

[0058] Fig. 2 is a flowchart illustrating exemplary steps of a data sharing method, according to a second embodiment of the disclosure. In this embodiment, the first instant messaging terminal and the second instant messaging terminal logged into a related account are not connected to the same LAN. The terminals can discover each other through a server. The illustrated instant messaging method in this embodiment can include the following process.

[0059] S201 , S202: The first instant messaging terminal and the second instant messaging terminal can each upload their respective gateway device information to a messaging server. In operation, the first instant messaging terminal and the second instant messaging terminal can transmit their respective gateway device information to the messaging server on a regular basis using an instant messaging application after logging into their instant messaging accounts. The gateway device information can include unique identification information (e.g., MAC addresses) of the gateway devices (e.g., routers) of the first and second instant messaging terminals on their respective LANs or their respective IP addresses on a public network.

[0060] S203: The messaging server can determine whether the first instant messaging terminal and the second instant messaging terminal can connect directly to each other. In operation, the messaging server can determine, based on the gateway device information of each terminal, whether the two terminals belong to the same LAN. If they do, it can be determined that the two terminals can connect directly with each other. [0061] S204: The first instant messaging terminal can obtain the result of the determination from the messaging server. In operation, when the user needs to transfer an instant messaging screen from the first instant messaging terminal to the second instant messaging terminal, the determination of whether the first instant messaging terminal and the second instant messaging terminal can connect directly with each other can be first obtained. When the first instant messaging terminal and the second instant messaging terminal can connect directly with each other, steps S I 01 -SI 04 in the first embodiment can be executed. When the first instant messaging terminal and the second instant messaging terminal cannot connect directly, S205 below can be executed.

[0062] S205: The first instant messaging terminal can transmit to the messaging server a data-sharing request directed to the second instant messaging terminal.

[0063] S206: The messaging server can forward the data-sharing request from the first instant messaging terminal to the second instant messaging terminal.

[0064] S207: The second instant messaging terminal can respond to the data- sharing request and transmit a reply permitting the request to the messaging server. The reply permitting data sharing can include an ID collection of one or more shareable data resources. In particular, the second instant messaging terminal, after receiving the data- sharing request, can display a message prompting whether or not to grant the data-sharing request. It can respond to the data-sharing request based on a user input selection. If the user chooses to reject the request, the second instant messaging terminal can send a reply to the first instant messaging terminal rejecting the request. If the user chooses to allow data sharing, the second instant messaging terminal can send a reply to the first instant messaging terminal granting the request. The reply permitting data sharing can include an ID collection of one or more shareable data resources, which can include at least one data resource ID. The data resource ID can be an ID of a data resource at the second instant messaging terminal that can be shared with the first instant messaging terminal or any other terminals. The user can manually set a data resource, a type of data resources, or a folder of data resources as shareable data resources. The second instant messaging terminal can generate a corresponding data resource ID based on a shareable data resource. The data resource ID can be of a format including, for example, the name, abstract, attribute, or thumbnail associated with the data resource. The ID collection of shareable data resources can include a list including multiple data resource IDs.

[0065] S208: The messaging server can forward the reply permitting data sharing from the second instant messaging terminal to the first instant messaging terminal.

[0066] S209: The first instant messaging terminal can transmit to the messaging server a data-reading request directed to the second instant messaging terminal. The data-reading request can include at least one data resource ID. In particular, the first instant messaging terminal, after receiving the reply from the second instant messaging terminal, can display the ID collection of the one or more shareable data resources in the reply to prompt the user at the first instant messaging terminal to select one or more data resources to be obtained. After receiving a selection command from a user, the first instant messaging terminal can transmit a data-reading request to the messaging server. The data-reading request can include at least one data resource ID selected by the user.

[0067] S210: The messaging server can forward the data-reading request from the first instant messaging terminal to the second instant messaging terminal.

[0068] S21 1 : The second instant messaging terminal can transmit to the messaging server one or more data resources corresponding to the at least one data resource ID in the data-reading request.

[0069] S212: The messaging server can forward the at least one data resource transmitted from the second instant messaging terminal to the first instant messaging terminal. This can allow the first instant messaging terminal to obtain one or more data resources from the second instant messaging terminal by routing information through the messaging server, when the first instant messaging terminal and the second instant messaging terminal cannot connect directly to each other.

[0070] Fig. 3 is a flowchart illustrating the exemplary steps of a data-sharing method, according to a third embodiment of the disclosure. The illustrated data-sharing method of this embodiment can include the following steps.

[0071] S301 : A messaging server can obtain, from a first instant messaging terminal, a data-sharing request directed to a second instant messaging terminal. In particular, because both the first instant messaging terminal and the second instant messaging terminal can be both logged into their respective instant messaging accounts, the data-sharing request transmitted from the first instant messaging terminal to the second instant messaging terminal using the instant messaging application can be obtained by the messaging server. The instant messaging application can be running in the background at the second instant messaging terminal. Therefore, it may not obtain the data-sharing request directly from the first instant messaging terminal and, instead, requires the messaging server to obtain and then forward the data-sharing request.

[0072] S302: The messaging server can obtain the operation status information of the instant messaging application at the second instant messaging terminal. In operation, the second instant messaging terminal can transmit the operation status information of its instant messaging application to the messaging server on a regular basis. Alternatively, it can also transmit the operating status information of its instant messaging application to the messaging server when there is a change to the operating status of the instant messaging application to notify the messaging server about the latest operating status.

[0073] S303: The messaging server can determine whether the instant messaging application at the second instant messaging terminal is running in the background. In operation, after the messaging server obtains, from the first instant messaging terminal, the data-sharing request directed to the second instant messaging terminal, the messaging server can determine, based on the latest operating status information of the instant messaging application uploaded from the second instant messaging terminal, whether the instant messaging application at the second instant messaging terminal is running in the background. When it is determined that the instant messaging application at the second instant messaging terminal is not running in the background, the messaging server can proceed as described in the previous two embodiments to process the data-sharing request. For example, it can determine whether the first instant messaging terminal and the second instant messaging terminal can connect directly with each other based on the gateway device information of the first and second instant messaging terminals. If they can, the data-sharing request can arrive at the second instant messaging terminal directly, and then the remaining process described in the first embodiment can be carried out. If the first instant messaging terminal and the second instant messaging terminal cannot connect directly, the messaging server can forward the received data-sharing request to the second instant messaging terminal to execute the process described in the second embodiment. When it is determined that the instant messaging application at the second instant terminal is running in the background, step S304 can be carried out.

[0074] S304: The messaging server can transmit to a terminal management server associated with the second instant messaging terminal a first push message including the data-sharing request. The terminal management server associated with the second instant messaging terminal can be, for example, an Apple terminal management server. The messaging terminal can transmit the first push message including the data-sharing request to the Apple terminal management server, requesting the Apple terminal management server to wake up a second instant messaging terminal under its management. The second instant messaging terminal can include, for example, an iPhone or iPad (i.e., smartphones and tablet PCs from Apple, both using iOS system)

[0075] S305: The terminal management server associated with the second instant messaging terminal can transmit a second push message including the data-sharing request to the second instant messaging terminal based on the first push message transmitted from the messaging server.

[0076] S306: The second instant messaging server can activate its instant messaging application in response to receiving the second push message and obtain the data-sharing request from the second push message.

[0077] S307-S312 can be the same as S207-S212 of the above-described second embodiment, respectively.

[0078] This embodiment can resolve the problem when the instant messaging application at the second instant messaging terminal is running in the background and cannot receive the data-sharing request from the first instant messaging terminal.

[0079] The embodiments of the disclosure also disclose a non-transitory computer-readable medium storing a program, when executed, can perform some or all of the steps in the embodiments disclosed above in view of Figs. 1 -3. [0080] Fig. 4 is a block diagram illustrating the exemplary structure of a first instant messaging terminal, according to an embodiment of the disclosure. The first instant messaging terminal in this embodiment can be a PC, mobile phone, tablet PC, smartphone, e-reader, laptop PC, in-car terminal or other network-enabled device. The first instant messaging terminal, as illustrated, can include at least the following components.

[0081] A terminal interacting module 401 that can interact with a second instant messaging terminal logged into a related account via an instant messaging application. In particular, the related account can be of an account of a friend or another member of a particular common group. It can also be the same account logged into at a different instant messaging terminal. The terminal interacting module 410 can interact with the second instant messaging terminal directly or by routing information through a messaging server. For example, in this embodiment, when the first instant messaging terminal and the second instant messaging terminal have already discovered each other, the terminal interacting module 410 can interact with the second instant messaging terminal directly. Alternatively, the first instant messaging terminal can obtain from the messaging server the result of determining whether a direct connection to the second instant messaging terminal can be established. Based on the result, it can then be determined whether the terminal interacting module 410 can interact directly with the second instant messaging terminal or it has to interact with the second instant messaging terminal by routing information through the messaging server.

[0082] The terminal interacting module can include the following units.

[0083] A sharing request transmitting module 41 1 that can transmit a data-sharing request to the second instant messaging terminal.

[0084] A reply obtaining unit 412 that can obtain a reply permitting data sharing from the second instant messaging terminal. The reply can include an ID collection of one or more shareable data resources. The ID collection of the shareable data resources can include at least one data resource ID. In particular, after the second instant messaging terminal receives the data-sharing request from the sharing request transmitting unit 41 1 , the second instant messaging terminal can display information prompting whether to grant the data sharing request. The second instant messaging terminal can choose whether or not to grant the data sharing request based on user input. If the user chooses not to grant the request, the second instant messaging terminal can transmit, to the first instant messaging terminal, a reply denying the data-sharing request. If the user chooses to accept the request, the second instant messaging terminal can transmit, to the first instant messaging terminal, a reply permitting the data-sharing request. The reply obtaining module 412 can then obtain the reply permitting the sharing request transmitted from the second instant messaging terminal. The reply permitting the sharing request can include an ID collection of the one or more shareable data resources, which includes at least one data resource ID. A data resource ID can be an identification of a data resource at the second instant messaging terminal that can be shared with the first instant messaging terminal or any other terminals. The user can manually set a data resource, a type of data resources, or a folder of data resources as shareable data resources. The second instant messaging terminal can generate a corresponding data resource ID based on a shareable data resource. The data resource ID can be of a format including, for example, the name, abstract, attribute, or thumbnail associated with the data resource. The ID collection of shareable data resources can include a list including multiple data resource IDs.

[0085] A data request unit 413 that can transmit a data-sharing request to the second instant messaging terminal. The data-reading request can include at least one of the data resource ID. In particular, after the reply obtaining unit 412 receives the reply from the second instant messaging terminal, the first instant messaging terminal can display the ID collection of the shareable data resources in the reply to prompt a user at the first instant messaging terminal to select one or more desirable data resources to be obtained. After receiving a selection command from the user, the data request unit 413 can transmit a data-reading request to the second instant messaging terminal. The data- reading request can include at least one data resource ID.
