Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the data transmission method provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 2, so that the data transmission method may operate based on the android operating system shown in fig. 2. That is, the processor or the terminal may implement the data transmission method provided by the embodiment of the present invention by running the software program in the android operating system.

In combination with the above, the solution provided herein will be explained with reference to the accompanying drawings.

The data transmission method according to the embodiment of the present invention is described below with reference to a flow chart of the data transmission method shown in fig. 3, and as shown in fig. 3, the data transmission method provided in the embodiment of the present invention specifically includes the following steps 301 to 307:

step 301: the first terminal display device is connected with the map.

In the embodiment of the present invention, the device connection map includes N terminal identifiers, where N is a positive integer greater than 1, and one terminal identifier indicates one terminal.

Optionally, in this embodiment of the present invention, the device connection map may display terminal identifiers corresponding to N terminals closest to the first terminal. Illustratively, the terminal identifier is information such as a head portrait, an account number, and the like of the terminal associated user.

Optionally, in this embodiment of the present invention, before the step 301, the method further includes a step 301 a:

step 301 a: in the case where a first terminal accesses a network device, the first terminal generates a device connection map.

In an embodiment of the present invention, the device connection map includes a terminal identifier of at least one terminal located within a network coverage area of the network device.

In this way, after the first terminal is successfully connected to the network device, a device connection map including terminal identifiers of a plurality of terminals located within a network coverage area of the network device is generated, so that a user can quickly identify a target terminal to be connected based on the terminal identifiers in the device connection map.

Step 302: the first terminal receives a first input of a target terminal identifier in the N terminal identifiers from a user.

Illustratively, the first input may include: the click input of the user on the target terminal identifier, or the slide input of the user on the target terminal identifier, or the press input of the user on the target terminal identifier, or other feasible inputs of the user on the target terminal identifier may be determined specifically according to actual use requirements, and the embodiment of the present invention is not limited.

For example, the click input may be a single click input, a double click input, or any number of click inputs; the click input may be a long-press input or a short-press input, the slide input may be a slide input in any direction, for example, a slide in an upward direction, a slide in a downward direction, a slide in a leftward direction, or a slide in a rightward direction, and a slide trajectory of the slide input may be a straight line or a curved line, and may be specifically set according to actual requirements.

Step 303: in response to the first input, the first terminal sends a first request message to the network device.

Step 304: the network equipment receives a first request message sent by a first terminal.

Step 305: the network device sends a second request message to the second terminal.

In this embodiment of the present invention, the first request message is used to request to establish a communication connection between the first terminal and the second terminal, and the second request message is used to request to establish a communication connection between the first terminal and the second terminal.

In the embodiment of the present invention, the second terminal is the terminal indicated by the target terminal identifier, and the first terminal and the second terminal are both terminals accessing the same network device.

Optionally, in this embodiment of the present invention, the first request message includes a first terminal ID of the first terminal and a second terminal ID of the second terminal. Thus, after receiving the first request message, the network device can quickly determine the request source device and the request receiving device based on the terminal ID contained in the first request message, and further quickly establish a D2D connection between the two terminals through the network device.

Illustratively, the first request message may further include at least one of: a request code requesting establishment of a communication connection between the first terminal and the second terminal, a device code of the network device. Wherein the first terminal ID includes: the method comprises the steps that equipment codes of a first terminal are obtained, and the first terminal is associated with information such as a head portrait and an account number of a user; the second terminal ID includes: and the second terminal is associated with information such as the head portrait, the account number and the like of the user.

Step 306: and the network equipment sends the first response message to the first terminal under the condition of receiving the second response message sent by the second terminal.

Step 307: and the first terminal establishes communication connection between the first terminal and the second terminal under the condition of receiving the first response message sent by the network equipment, and transmits the target data through the communication connection.

In this embodiment of the present invention, the first response message is used to indicate that the second terminal allows establishing a communication connection with the first terminal.

Illustratively, the first terminal can also establish communication connection with a plurality of second terminals at the same time.

For example, the first terminal sends a request message to the terminals corresponding to the plurality of terminal identifications in the device connection map, where each request message includes a second terminal ID of a different terminal, and after the plurality of terminals receive the connection request, the first terminal ID of the first terminal can be checked according to the connection request, and whether to establish a communication connection with the first terminal is determined according to the first terminal ID.

In the data transmission method provided by the embodiment of the present invention, a first terminal displays a device connection map including N terminal identifiers, one terminal identifier indicates one terminal, and after receiving a first input of a target terminal identifier from among the N terminal identifiers by a user, the first terminal requests to establish a communication connection between the first terminal and a second terminal by sending a first request message to the network device because the second terminal and the first terminal indicated by the target terminal identifier are both accessed to the same network device, so that when the first terminal receives a first response message sent by the network device to indicate that the second terminal allows establishing the communication connection with the first terminal, the communication connection between the first terminal and the second terminal can be established, thereby enabling direct connection between the first terminal and the second terminal without passing through the network device, and then the short-distance, safe and convenient data sharing among the terminals is realized through the communication connection.

Optionally, in this embodiment of the present invention, when the first request message includes a second terminal ID of the second terminal, the step 305 may further include the steps 305a1 and 305a 2:

step 305a 1: and the network equipment analyzes the first request message to acquire the ID of the second terminal.

Step 305a 2: the network device searches for a second terminal from terminals accessing the network device based on the second terminal ID, and transmits a second request message to the second terminal.

Thus, after receiving the first request message, the network device can quickly determine the request receiving device based on the second terminal ID included in the first request message, and can further establish a D2D connection between the two terminals as soon as possible through the network device.

Optionally, in this embodiment of the present invention, in a case that the second response message includes the first terminal ID of the first terminal, the step 306 may further include the step 306b1 and the step 306b 2:

step 306b 1: and the network equipment analyzes the second response message to acquire the first terminal ID.

Step 306b 2: the network device searches for the first terminal from terminals accessed to the network device based on the first terminal ID, and sends a first response message to the first terminal.

Thus, after receiving the second response message, the network device can quickly determine the request source device based on the first terminal ID included in the second response message, and can further establish a D2D connection between the two terminals as soon as possible through the network device.

For example, after the first terminal sends the first request message to the network device, the network device obtains the device code of the second terminal included in the first request message by parsing the first request message, and searches for the second terminal based on the device code, thereby sending the second request message to the second terminal. After receiving the second request message, the second terminal may check a first terminal ID included in the second request message, then determine whether to establish a connection with the first terminal according to the first terminal ID, if the second terminal agrees to establish a connection, feed back a second response message to the network Device, the network Device obtains the first terminal ID by parsing the second response message, and send a first response message to the first terminal, after receiving the first response message, the first terminal completes a terminal-to-terminal (Device-to-Device, abbreviated as D2D) connection between the first terminal and the second terminal (i.e., the above communication connection), and after the connection is successful, the first terminal and the second terminal may perform data transmission. On the contrary, if the second terminal does not agree with the connection, the second response message is not fed back to the network device, and the D2D connection between the first terminal and the second terminal cannot be established.

Optionally, in this embodiment of the present invention, the N terminal identifiers include a first type terminal identifier and a second type terminal identifier, where a terminal indicated by the first type terminal identifier is a terminal accessing the network device, and a terminal indicated by the second type terminal identifier satisfies a first condition and a second condition. Wherein the first condition is: the current position of the terminal is positioned in the network coverage range of the network equipment; the second condition includes at least one of: and the terminal which is not accessed to the network equipment rejects the terminal which establishes communication connection with other terminals.

In an example, after a terminal is successfully connected to a network device, a user of the terminal may select to turn on or turn off a device connection map, and when the user selects to turn on the device connection map, the terminal is indicated by a first type of terminal identifier in the device connection map, and otherwise, when the user selects to turn off the device connection map, the terminal is indicated by a second type of terminal identifier in the device connection map.

Illustratively, if a certain terminal identifier is a first-class terminal identifier, it indicates that the terminal indicated by the terminal identifier accepts to establish communication connection with other terminals; otherwise, if a certain terminal identifier is the second type of terminal identifier, it indicates that the terminal indicated by the terminal identifier does not accept to establish communication connection with other terminals.

By way of example, example 1: the first type terminal identification and the second type terminal identification can be represented by icons in two colors, and the icons in the two colors can be icons with the same shape but different colors, such as: the first type of terminal identifier is indicated by a red circular icon, the second type of terminal identifier is indicated by a green circular icon, and example 2: the first type terminal identifier and the second type terminal identifier may also be represented by two icons with different shapes and the same color, for example, a circle indicates the first type terminal identifier, and a diamond indicates the second type terminal identifier. The color may be any possible color such as red, yellow, blue, green, etc., and the shape may be any possible shape such as a circle, a rectangle, a triangle, a diamond, or a polygon, which may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

For example, the terminal identifier displayed in the device connection map may be divided into the following two display modes.

The first display mode is as follows: and all the N terminal identifications displayed by the equipment connection map are first-class terminal identifications.

For example, the following steps are carried out:

as shown in fig. 4, after the first terminal accesses a 5G base station (i.e. a network device), a device connection map (e.g. 41 in fig. 4) is displayed in a main interface of the first terminal, user icons (i.e. the above-mentioned N terminal identifiers) corresponding to 6 terminal users are displayed in the device connection map, which are respectively the user 1, the user 2, the user 3, the user 4, the user 5, and the user 6, and all of the user 1 to the user 6 are first type identifiers, i.e. the above-mentioned user 1 to the user 6 all allow connection to be established with other terminals, so that the user of the first terminal can determine a terminal to establish connection according to the icons and names of the user 1 to the user 6, and when the user of the first terminal determines to establish a D2D connection with the terminal corresponding to the user 1, the user of the first terminal can click (i.e. the above-mentioned first input) the user icon of the user 1 (i.e. the above-, i.e., 42 in fig. 4), thereby sending a first request message to the network device.

The second display mode is as follows: among the N terminal identifiers displayed on the device connection map, one part may be a first type terminal identifier and the other part may be a second type terminal identifier.

For example, the following steps are carried out:

as shown in fig. 5, the device connection map (51 in fig. 5) displayed by the first terminal displays the user avatars corresponding to 6 terminal users (i.e., the above-mentioned N terminal identifiers), since solid circular icons (i.e., the above-mentioned first type terminal identifiers, 52a in fig. 5) are displayed under the user avatars of the users 1, 2, 4, 5, and the icons displayed under the user avatars of the users 3 and 6 are hollow circular icons (i.e., the above-mentioned second type terminal identifiers, 52b in fig. 5), the user of the first terminal can determine the user to establish a connection according to the user avatars and names (i.e., the above-mentioned terminal identifiers) in the users 1, 2, 4, 5, and after determining that a D2D connection is to be established with the terminal corresponding to the user 1, the user of the first terminal can click (i.e., the above-mentioned first input) the user avatar of the user 1 (i.e., the above-mentioned target terminal identifier), a first request message requesting the establishment of a terminal corresponding to the avatar of the user 1 is transmitted.

Therefore, the N terminal identifications displayed in the equipment connection map display the N terminal identification classification marks, so that a user can quickly and intuitively find the terminal identification to be established with communication connection in the equipment connection map, and the terminal corresponding to the terminal identification can quickly establish communication connection.

Optionally, in an embodiment of the present invention, after the step 304, the data transmission method further includes steps a1 to A3:

step A1: the first terminal displays M information identifications.

In an embodiment of the present invention, the one information identifier indicates information, and the information includes at least one of the following: pictures, files, audio, video, contacts, and applications.

Step A2: and the first terminal receives a second input of the target information identifier in the M information identifiers from the user.

Illustratively, the target information identifier is at least one of M information identifiers.

Illustratively, the second input may include: the click input of the user on the target information identifier, or the slide input of the user on the target information identifier, or the press input of the user on the target information identifier, or other feasible inputs of the user on the target information identifier may be determined specifically according to actual use requirements, and the embodiment of the present invention is not limited.

It should be noted that, the above-mentioned click input and the above-mentioned slide input may refer to the above-mentioned description of the first input, and are not described herein again.

Step A3: and responding to the second input, and the first terminal sends the information corresponding to the target information identification to the second terminal.

For example, in a case that a first terminal may establish a communication connection with a second terminal, the first terminal may directly select a target information identifier to implement data transmission with the second terminal.

For example, taking the above information identifier as a picture, as shown in fig. 6, after a connection is established between the first terminal and the second terminal, if a user of the first terminal wants to transmit a picture to the second terminal, an album may be called, an album interface (e.g. 61 in fig. 6) currently displayed by the first terminal is displayed on the album interface 61, thumbnails of 6 pictures (i.e. the above information identifier) are displayed on the album interface 61, and the 6 pictures are respectively picture 1, picture 2, picture 3, picture 4, picture 5, and picture 6. If the user of the first terminal wants to send the picture 2 to the second terminal, the user can click on the thumbnail of the picture 2 (i.e. the target information identifier, such as 62 in fig. 6), so as to directly send the picture 2 to the second terminal.

Therefore, after the first terminal and the second terminal establish communication connection, the target information identifier can be directly selected, and the information corresponding to the target information identifier is sent, so that the whole information sending process is more convenient.
