Detailed ways

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

A local area network can be a type of network, and its coverage can generally be within a few kilometers. It has the characteristics of convenient installation, cost saving, and easy expansion, which makes it widely used in various offices. The local area network can realize functions such as file management, application software sharing, printer sharing, etc. In the process of use, by maintaining the security of the local area network network, it can effectively protect the security of data and ensure the normal and stable operation of the local area network network. Data sharing is to allow users who use different computers and different software in different places to read other people's data and perform various operations, calculations and analysis.

As an example, in the related art, people's demands for data sharing are getting higher and higher, but since there is no corresponding identity relationship established between users, the manner of data sharing and transmission is very complicated. For example, the sender and the receiver need to log in as the premise, build a user relationship between the sender and the receiver, and then use the instant messaging function to send messages to achieve data sharing. Or jump out of the current app and use other apps that establish user relationships for data transmission communication. It can be seen that, in the above process, the data sharing based on the user relationship limits the data transmission between the data sharing parties and greatly increases the threshold for data sharing.

In this regard, one of the core inventive points of the present invention is that for the sending terminal, it can respond to the data sharing instruction input by the user in the application program, according to the current network information obtained after the user's authorization, to search for the receiving terminal that belongs to the same local area network as itself. The terminal, if there is a receiving terminal that belongs to the same local area network as itself, can determine the target data corresponding to the data sharing instruction, and send the target data to the receiving terminal, so that when the user initiates data sharing in the application, the terminal can search for the target data. Other terminals located in the same local area network send shared data to them. In the case of running the same application, terminals based on the same local area network can avoid building user relationships for data sharing, effectively lowering the threshold for data sharing.

Specifically, referring to FIG. 1, it shows a flowchart of steps of a data transmission method provided in an embodiment of the present invention, which is applied to a sending terminal, and may specifically include the following steps:

Step 101, acquiring network information of the sending terminal;

For the sending terminal and the receiving terminal, it may include user terminals such as desktop computers, notebook computers, tablet computers, and mobile terminals, and corresponding application programs can be run in the user terminals, and the application programs may include life applications, audio applications, games In the process of running the same application between the sending terminal and the receiving terminal, the sending terminal can initiate data sharing, and if the conditions are met, send the shared data to the receiving terminal.

In a specific implementation, in the process of running a corresponding application program on the terminal, the application program may acquire network information of the network to which the terminal belongs, so as to perform data sharing according to the network information. It should be noted that the acquisition of network information proposed in the embodiments of the present invention is performed under the premise of complying with the corresponding data protection regulations and policies of the local country and authorized by the corresponding device owner.

Step 102, in response to the data sharing instruction in the application, search for a receiving terminal that belongs to the same local area network as the sending terminal according to the network information;

When the sending terminal is running the application, when the user needs to share data, it can input the corresponding data sharing instruction in the application, and then the terminal can respond to the data sharing instruction in the application, and obtain the data according to the authorization of the user. Search for the receiving terminal that belongs to the same local area network as the swearing sending terminal, so as to send data to it.

The network information may include the subnet mask of the sending terminal, and the subnet mask may be used to indicate which bits of an IP address identify the subnet where the terminal is located and which bits identify the bit mask of the terminal. Combined with the IP address, the network address of the terminal can be determined. Optionally, the subnet mask may be a 32-bit address, which is used to mask a part of the IP address to distinguish the network identifier from the terminal identifier, and to indicate whether the IP address is on the local area network or the wide area network.

In a specific implementation, in the process of processing related data, when the user needs to share the related data to another terminal, the data can be shared through the sharing path provided in the application program, and the sending terminal can respond to the in-application program. It displays the corresponding terminal search interface, and searches for the receiving terminal that belongs to the same local area network as the sending terminal through the subnet mask of the sending terminal obtained earlier, so as to send the corresponding data to it.

Specifically, the network information may also include the first IP address of the sending terminal, and the sending terminal may first search for at least one target terminal with the same subnet mask as the sending terminal. If it finds at least one target terminal with the same subnet mask The terminal can further obtain the second IP address of each target terminal, and then the sending terminal can use the first IP address and the subnet mask to calculate the first network address of the sending terminal, and use the second IP address and the first subnet mask. mask, calculate the second network address of the target terminal, then compare the second network address of each target terminal with the first network address of the sending terminal, and assign the target corresponding to the second network address that is the same as the first network address The terminal acts as a receiving terminal that belongs to the same local area network as the sending terminal.

In addition, if there is no second network address that is the same as the first network address, second prompt information for the target terminal is displayed, and the second prompt information is information that each target terminal and the sending terminal are not in the same local area network.

Optionally, the subnet mask can be used to determine whether the IP addresses of different terminals are on a local area network or a wide area network, and the IP address can be used to represent the unique address of the terminal. Obtain the network address of the terminal. If the network address is the same, it can indicate that different terminals are located in the same local area network, so that the sending terminal can first search for the target terminal also located in the local area network through the subnet mask, and then according to the combination of the subnet mask and the IP address. Calculate the network address of each terminal, and then filter out the receiving terminal located in the same local area network as the sending terminal through network address comparison, so as to send the corresponding target data to it, so that when the user initiates data sharing in the application program, Terminals can search for other terminals in the same local area network and send shared data to them. In the case of running the same application, terminals based on the same local area network can avoid building user relationships for data sharing, effectively lowering the threshold for data sharing.

In an optional embodiment, when the user inputs the corresponding data sharing instruction in the application program, the terminal may first detect whether it is currently connected to the network, and in the case of accessing the network, perform the aforementioned process of searching for the receiving terminal; if If the terminal is not connected to the network, corresponding prompt information may be output to prompt the user to connect the terminal to the network first, and then perform data sharing.

Step 103: If there is a receiving terminal that belongs to the same local area network as the sending terminal, determine target data corresponding to the data sharing instruction, and send the target data to the receiving terminal.

In the embodiment of the present invention, when the sending terminal finds the receiving terminal that belongs to the same local area network through its own IP address and subnet mask, it can determine the target data corresponding to the data sharing instruction, and then send the target data to the receiving terminal. terminal. The target data may include at least one of pictures, audio, video, documents, and posts, so that when a user initiates data sharing in an application, the terminal can search for other terminals located in the same local area network and send the shared data to them. , In the case of running the same application, terminals based on the same local area network can avoid building user relationships for data sharing, effectively lowering the threshold for data sharing, and at the same time, data transmission in the same local area network can effectively ensure the stability of data transmission and transfer speed.

In a specific implementation, after determining the target data corresponding to the data sharing instruction, the sending terminal may send the target data to the server, and then send the target data to the receiving terminal through the server. When the receiving terminal is running the same application program, after receiving the data sharing request sent by the server, it can perform corresponding data processing according to the user operation of the user to which the receiving terminal belongs (including operations such as confirming sharing and refusing sharing), If the user confirms sharing, the receiving terminal can respond to the data receiving request, receive the target data, and then display the corresponding target data; if the user refuses to share, the server can obtain the response message sent by the receiving terminal, and send the response message It is sent to the sending terminal, and the sending terminal displays a response message to inform the user of the failure to share data.

In addition, if the sending terminal does not find a receiving terminal that belongs to the same local area network as the sending terminal according to its own IP address and subnet mask, it can display the first prompt information for the data sharing instruction, and the first prompt information is that it does not exist and is sent. The information of the terminals that belong to the same local area network to inform the user that there is no terminal that can share data nearby, so that through the above process, the sending terminal can search for the receiving terminal that can share data in the same local area network based on the network information, avoiding the need for data sharing. By establishing user relationships for data sharing, the threshold for data sharing is effectively lowered.

It should be noted that the embodiments of the present invention include, but are not limited to, the above examples. It can be understood that those skilled in the art can also make settings according to actual needs under the guidance of the embodiments of the present invention, which is not limited by the present invention.

For the same application program run by the sending terminal and the receiving terminal, a network monitoring function can be configured in the application program. After obtaining user authorization, the network monitoring function of the terminal can be used to monitor the network of the terminal when the application is running in the foreground, so that when the user initiates data sharing in the application, the corresponding receiving terminal can be searched for data based on the network information. shared. Specific processes can include:

1. The application can monitor the network of the terminal it belongs to in real time. When the network changes, it uploads the IP address and subnet mask of the current network and other related data to the server in real time for later functional verification.

2. When a user initiates a data sharing requirement (such as sharing a listing post):

The application can first check whether the terminal to which it belongs is connected to the Internet. When the terminal is not currently connected to the Internet, it can output corresponding prompt information to prompt the terminal to connect to the Internet, and suspend the data sharing process before connecting to the Internet.

When the application detects that the terminal to which it belongs is connected to the network, it can judge according to the IP address and subnet mask reported by the network monitoring, and search for the receiving terminal with the same subnet mask as the terminal currently initiating data sharing. For the search process of the receiving terminal, the sending terminal can first find out the target terminal with the same subnet mask, obtain the IP address of the target terminal, and then calculate the network address IP&Mask of each terminal (including the sending terminal and the target terminal) respectively, and then The target terminal with the same IP&Mask as the sending terminal is used as the receiving terminal in the same local area network, so that the receiving terminals in the same local area network can be filtered out through two filters.

When a shareable terminal group is found, the relevant data such as the post ID of the current data (a post) are packaged and sent to the server. After receiving the shared data content, the server can send it to eligible receiving terminals. . The receiving terminal can confirm whether to receive data through the sharing request popped up in the application program, and receive the corresponding target data after confirming the reception, so that when the user initiates data sharing in the application program, the terminal can find other devices located in the same local area network. Terminals and send shared data to them. In the case of running the same application, terminals based on the same local area network can avoid building user relationships for data sharing, effectively lowering the threshold for data sharing.
