Description

A file transmission method, sending device, receiving device and terminal

technical field

Embodiments of the present invention relate to the technical field of terminals, and in particular, to a file transmission method, a sending device, a receiving device, and a terminal.

Background technique

With the development of terminal technology, users use terminals to transmit files more and more frequently, and users have higher and higher requirements for transmission time. Commonly used point-to-point file transfer tools include Bluetooth transfer, wireless fidelity (Wireless-Fidelity, WiFi) transfer and other various fast transfer tools.

Assuming that terminal A sends a file to terminal B through Bluetooth, then terminal A and terminal B can first establish a connection through Bluetooth. After the connection is established, terminal A first determines the file to be sent selected by the user, and receives the sending operation triggered by the user, and then the terminal A then sends a request message to terminal B that needs to transmit the file. After terminal B receives the request message sent by terminal A, if terminal B obtains the user-triggered operation of agreeing to the transmission, then terminal B replies to terminal A with the request message. The response message, after receiving the response message, terminal A starts to send the file to terminal B.

However, in the above transmission mode, when terminal A sends a file to terminal B, since terminal A needs to establish a connection with terminal B, the user selects the file to be sent, sends a request message to terminal B, and receives the data sent by terminal B. After a series of actions such as a response message, the file is sent to the terminal B, so the file transfer between the terminal A and the terminal B takes a long time.

The kernel layer is the operating system layer of the Android operating system and belongs to the bottom layer of the Android operating system software layer. The kernel layer provides core system services and hardware-related drivers for the Android operating system based on the Linux kernel.

Taking the Android operating system as an example, in this embodiment of the present invention, a developer can develop a software program for implementing the file transfer method provided by the embodiment of the present invention based on the system architecture of the Android operating system as shown in FIG. The method of file transfer can be run based on the Android operating system as shown in FIG. 1 . That is, the processor or the terminal device can implement the file transmission method provided by the embodiment of the present invention by running the software program in the Android operating system.

It should be noted that, the file transfer in the embodiment of the present invention is performed on the premise that the transfer connection has been established. Among them, the transmission connection established by the sending device and the transmission device may be a connection established through Bluetooth, a transmission connection established through a physical connection, a transmission connection established through WiFi, or a transmission connection established through a fast transmission tool. The transmission connection is not specifically limited in this embodiment of the present invention.

The following is an exemplary description of a file transmission method according to an embodiment of the present invention with reference to FIG. 2 .

FIG. 2 is a schematic diagram of an interaction flow of a file transmission method provided by an embodiment of the present invention, and the method includes steps 201 to 207:

Step 201: The sending device acquires the first selection operation of the user on the first file.

Wherein, the first file includes: the first file selected by the user in the sending device.

It should be noted that the first file may include multiple files. For example, the first file is multiple pictures selected by the user through a select-all operation in an album, and the sending device may send the pictures according to the default order in the album.

Optionally, the type of the first file may be any type of document, picture, audio, video, or web page link, which is not specifically limited in this embodiment of the present invention. The first selection operation may specifically be operations such as clicking, pressing, or sliding on the first file by the user, or may be selecting the first file through a voice control terminal, which is not specifically limited in this embodiment of the present invention.

Step 202: In response to the first selection operation, the sending device sends the first file to the receiving device.

Step 203: The receiving device receives the first file sent by the sending device.

It should be noted that when the receiving device starts to receive the first file sent by the sending device, the receiving device may display the received first file on the user interface, or may not display the received first file on the display interface, which is not specifically limited in this embodiment of the present invention .

Step 204: The sending device acquires the second selection operation of the user on the second file.

Wherein, the second file includes: the file selected by the user in the sending device after the user selects the first file.

Optionally, the second file may be of the same type as the first file, or may be of a different type than the first file, for example, the first file is a picture, and the second file may be either a picture or audio or video. The embodiment does not specifically limit this.

Step 205: In response to the second selection operation, the sending device sends the second file to the receiving device.

It can be understood that when files are sent serially in one connection, when the data of the first file is small, the first file may have been sent before the second selection operation, and after the user selects the second file, the user can start sending The receiving device sends the second file. When the data of the first file is large, the first file may be being sent before the second selection operation. After the user selects the second file, the sending device waits for the first file to be sent. Start sending the second file to the receiving device; when sending files in parallel in one connection, the sending device does not need to wait for the first file to finish sending, as long as the sending device obtains the user's second selection operation, the sending device can start sending the first file to the receiving device. Second file.

Step 206: The receiving device receives the second file sent by the sending device.

Step 207: The sending device displays the sending status of the sending file on the current interface of the sending device.

Wherein, the sending file includes a first file and a second file.

Optionally, the sending status includes waiting for sending, sending and finishing sending. Of course, the sending status can also be expressed as a percentage of sending completion, for example, 0% means waiting to send, greater than 0% and less than 100% is sending, and equal to 100% means sending completed, which is not specifically limited in this embodiment of the present invention.

It should be noted that the sending device may display the sending status of the sending file on the current interface after the user selects a file, or the sending device may display the sending status of the sending file on the current interface after the user selects all the sending files. This embodiment of the present invention does not specifically limit this.

Fig. 3 is a kind of timing comparison diagram of sending file provided in the embodiment of the present invention, (a) in Fig. 3 is the timing diagram of traditional sending file, (a) among Fig. 3 is to obtain user's selection file at first, After the user selects the file, the user sends a transmission command to the receiving device, and then starts to transmit the file. (b) in FIG. 3 is a sequence diagram for sending a file according to an embodiment of the present invention. While selecting the file, the user sends a transmission command to the receiving device. , and start transferring files.

若根据图3中的(b)所示的时序图，用户在选择第一张照片时，第一张照片即可开始发送，30s的选择时间可以发送3M的数据，也就是说30s的选择时间发送设备可以将一张照片发送完毕，则从用户选照片到发送完毕的总时间为

因此可以看出本发明实施例提供的文件传输的方法可以缩短文件传输的时间。当用户选择的时间越长时，本发明实施例提供的文件传输的方法的缩短传输时间的效果越明显，最终可能用户选择完毕后向接收设备发送目标指令时，接收设备已经将所有文件接收完毕。Exemplarily, it is assumed that user A needs to select 5 photos from 10 photos and send them to the receiving device where user B is located through the sending device, and each photo is 3 megabytes (M). The rate is 0.1 megabits per second (M/s), and the user-selected time length is 30s. If according to the sequence diagram shown in (a) of Figure 3, the user first selects a photo, and then clicks send to start sending, the total time from the user's selection to the completion of sending is

According to the sequence diagram shown in (b) in Figure 3, when the user selects the first photo, the first photo can be sent, and the selection time of 30s can send 3M data, that is, the selection time of 30s The sending device can finish sending a photo, then the total time from the user selecting the photo to the sending is

Therefore, it can be seen that the file transmission method provided by the embodiment of the present invention can shorten the time of file transmission. When the time selected by the user is longer, the effect of shortening the transmission time of the file transmission method provided by the embodiment of the present invention is more obvious. In the end, it is possible that when the user sends the target instruction to the receiving device after the selection is completed, the receiving device has already received all the files. .

In the file transmission method provided by the embodiment of the present invention, the sending device obtains a user's selection operation on a first file, where the first file includes: the first file selected by the user in the sending device; and responds to the first selection operation Sending the first file to the receiving device; and acquiring a second selection operation of the user on the second file, the second file including: the file selected by the user in the sending device after selecting the first file; and responding to the first file The second selection operation is to send the second file to the receiving device; and display the sending status of the sending file on the current interface of the sending device, and the sending file includes the first file and the second file. With this solution, after the user selects a file, the file can be sent to the receiving device. Compared with the prior art, the embodiment of the present invention does not need to start sending the file to the receiving device after the user has selected all the files. It reduces the time for transferring files and improves the transfer efficiency.

Optionally, after step 207, the file transmission method provided by the embodiment of the present invention further includes steps 208 and 209:

Step 208: The receiving device acquires the user's determined receiving operation.

The determining operation is used to trigger the receiving device to display the receiving state of the received file on the current interface of the receiving device, and the received file includes the first file and the second file.

Optionally, the receiving state may include waiting to receive, receiving, and receiving completed. Of course, it can also be expressed by the percentage of file receiving completion, for example, 0% means waiting to receive, greater than 0% and less than 100% means receiving, and equal to 100% means complete receiving, which is not specifically limited in this embodiment of the present invention.

Step 209: In response to determining the receiving operation, the receiving device displays the receiving status of the received file on the current interface of the receiving device.

It should be noted that, in this solution, when a file is transferred between the sending device and the receiving device, the receiving device displays the receiving state of the receiving file on the display interface of the receiving device after obtaining the user's click OK operation.

Based on this solution, after the receiving device obtains the user's determination of the receiving operation, the receiving device displays the receiving state of the received file to the user on the display interface of the receiving device. Compared with the prior art, since the receiving state of the received file is displayed before the receiving device , the receiving device has already started to receive the file, so the time for transferring the file can be reduced, the efficiency of transferring the file can be improved, and the user experience of the receiving device can be better.

In a possible implementation manner, before step 207, the file transmission method provided by the embodiment of the present invention further includes step 210:

Step 210: The sending device acquires the user's determined sending operation.

Wherein, determining the sending operation is used to trigger the sending device to display the sending status of the sending file on the current interface of the sending device.

Optionally, the user's determining operation for sending may be a user's click, touch, sliding, or a determination operation through voice input on the display interface of the sending device, which is not specifically limited in this embodiment of the present invention.

Further, step 207 can be realized by step 207a:

Step 207a: In response to determining the sending operation, the sending device displays the sending status of the sending file on the current interface of the sending device.

It should be noted that, in the embodiment of the present invention, "the user's determination of sending operation" refers to that after a transmission connection is established, after the user selects the file to send in the sending device, the user selects "Start" on the display interface of the sending device. Send" or "OK Send" operation.

It should be noted that, in this scenario, only when the sending device obtains the user's confirmed sending operation, the sending device will display the sending status of the sending file on the current interface of the sending device.

Based on this solution, the sending device displays the sending status of the sending file to the user on the current interface of the sending device after the sending device obtains the user's determined sending operation. Since the sending device starts sending the first file after obtaining the user's first operation, after obtaining the user's confirmed sending operation, some files are being sent, and some files may have already been sent. If it is long, it is obtained that after the user has completed the selection of the last file to send, after the user has confirmed the sending operation, it is possible that the sending files before the last sending file have all been sent. Therefore, the time for transferring files is reduced and the efficiency of transferring files is improved. Thereby, the experience of the user of the sending device is improved.

In a possible implementation manner, before step 207, the file transmission method provided by the embodiment of the present invention further includes step 211 and step 212:

Step 211: The sending device acquires the user's first cancellation operation on the third file.

Wherein, the third file includes at least one file among the sent files.

It can be understood that the first cancellation operation is that when the user chooses to send files, the operation of at least one of the files may be canceled because the number of files to be sent this time is exceeded, or the previously selected file may be canceled because the user wishes to send another better file. The operation of canceling all files may also be selected because the user needs to interrupt the transmission. The embodiment of the present invention does not specifically limit the number of files canceled by the user.

Step 212: In response to the first cancel operation, the sending device cancels sending the third file.

Exemplarily, when the user chooses to transmit pictures, the user may cancel the selected photos 1 and 2 after selecting multiple photos, and re-select other photos. At this time, the terminal obtains the cancellation of the selected photos 1 and 2. After the operation, cancel sending of Photo 1 and Photo 2.

Optionally, "the sending device cancels sending the third file" in the above method embodiment may be implemented in the following three ways:

Mode 1: If the third file is an unsent file, the sending device cancels the instruction to send the third file.

It should be noted that the third file is a file that has been selected by the user and is still queued for sending, and canceling the instruction to send the third file means that the terminal will no longer send the third file.

Mode 2: If the third file is a file being sent, the sending device cancels sending the third file, and sends a first notification message to the receiving device, where the first notification message is used to instruct the receiving device that has received the first notification message to delete the third file. Received data in three files.

Mode 3: If the third file is a file that has been sent, the sending device sends a first notification message to the receiving device.

Based on this solution, when the sending device sends a file to the receiving device, the sending device can cancel the sending of the third file in different sending states, which not only reduces the storage resources occupied by the received data in the third file in the receiving device, but also reduces the storage resources occupied by the received data in the third file in the receiving device. Before displaying the sending status to the user, the sending device cancels the sending of the third file in different sending status, and the user of the receiving device can also be made unaware of the canceling operation, which improves the user's experience during file transfer.

In a possible implementation manner, before step 208, the file transmission method provided by the embodiment of the present invention further includes step 213 and step 214:

Step 213: The receiving device receives the first notification message sent by the sending device.

The first notification message is used to instruct the receiving device to delete the received data in the third file; the third file is a file being received by the receiving device or a file that has been received.

Step 214: The receiving device deletes the data received by the receiving device in the third file according to the first notification message.

Based on this solution, after the receiving device receives the first notification message sent by the sending device, the receiving device deletes the received data in the third file according to the first notification message. The receiving device does not display the transmission status of the received file to the user before determining the reception, so that the user of the receiving device is unaware that the receiving device deletes the data that has been received, and the user experience is improved.

After the receiving device displays the receiving state of the received file to the user, the user of the receiving device can choose to refuse to receive one or more files, and the file transmission method provided by the embodiment of the present invention can be implemented as follows.

In a possible implementation manner, after step 207, the file transmission method provided by the embodiment of the present invention may further include steps 215 to 220:

Step 215: The receiving device acquires an operation of the user refusing to receive the fourth file.

The fourth file includes at least one of the following: a file currently waiting to be received by the receiving device, a file currently being received by the receiving device, and a file that the receiving device has completed receiving.

It should be noted that the fourth file asks one of the files displayed by the receiving device on the display interface of the receiving device, wherein, in this embodiment of the present invention, the files displayed on the display interface of the receiving device include files in various receiving states, and the user can Reject any received file with any receiving status.

It can be understood that when the user of the receiving device determines that the fourth file occupies too much storage resources, or when the user needs to interrupt file transmission, or when the user does not want to receive the fourth file, the user can refuse to receive the fourth file. This is not specifically limited.

Step 216: In response to the user's operation of refusing to receive the fourth file, the receiving device sends a second notification message to the sending device.

The second notification message is used to instruct the receiving device to refuse to receive the fourth file.

Step 217: The sending device receives the second notification message sent by the receiving device.

Step 218: The sending device sends a third notification message to the receiving device according to the second notification message.

The third notification message is used to instruct the receiving device to delete the received data in the fourth file.

Step 219: The receiving device receives the third notification message sent by the sending device.

Step 220: The receiving device deletes the data received by the receiving device in the fourth file according to the third notification message.

Based on this solution, when the receiving device receives an operation that the user refuses to receive the fourth file, the receiving device can send a second notification message to the sending device, so that the sending device cancels sending the fourth file, if the fourth file is currently waiting for the receiving device to receive If the fourth file is a file being received by the receiving device or a file that has been received, the sending device sends a third notification message to the receiving device, so that the receiving device deletes the received data to avoid The storage space of the receiving device is occupied by the data that has been received due to the interruption, and the user experience is improved.

In a possible implementation manner, before step 208, the file transmission method provided in this embodiment of the present invention may further include steps 221 to 223:

Step 221: The sending device sends the target instruction to the receiving device.

The target instruction is used to instruct the receiving device to receive the received file.

Step 222: The receiving device receives the target instruction sent by the sending device.

Step 223: The receiving device displays a prompt message on the current interface of the receiving device according to the target instruction.

The prompt message is used to prompt the user whether to confirm to receive the received file.

Optionally, the prompt message may be displayed in a notification bar or in a prompt box, which is not specifically limited in this embodiment of the present invention.

Further, step 208 can be specifically implemented by step 208a:

Step 208a: The receiving device obtains the operation of receiving the received file by the user confirming the prompt message on the current interface.

It should be noted that, if the connection established by the sending device and the receiving device is sending a file, and the receiving device needs to obtain the user's confirmation of receiving the file, the file transmission method provided by the embodiment of the present invention will obtain the user's confirmation of receiving the file when the receiving device obtains. Before, the sending and receiving device receives the sent file, and after the user confirms the reception, the receiving device displays the receiving state of the received file to the user.

Based on this solution, before the user determines to receive the received file, that is to say, the user of the receiving device has not seen the receiving state of the received file received by the receiving device, the receiving device has already started to receive data of part of the file, when the sending device sends the data to the receiving device The target instruction, the target instruction instructs the receiving device to receive the received file, and the receiving device prompts the user whether to confirm the reception after receiving the target instruction. In the receiving state, the data of some files may be being received or have been received. For the user on the receiving end, the file transfer time is reduced, which improves the user experience.

In a possible implementation manner, the method for file transmission provided by the embodiment of the present invention further includes step 224:

Step 224: After acquiring the user's selection operation on a file, the sending device saves the correspondence between the identifier of the file, the sending state of the file, and the display state of the file.

Exemplarily, Table 1 is an example of a corresponding table provided by the embodiment of the present invention. Among them, Table 1 takes as an example that the display state of the file is "hidden" before the sending end user confirms the sending, and the file display state is "displayed" after the sending end user confirms the sending.

Table 1

file identification send status Display state File 1 send completed hide file 2 send completed hide file 3 sending hide file 4 waiting to send hide file 5 waiting to send hide

Among them, Table 1 indicates that the sending status of file 1 and file 2 at the current time is "sending completed", the sending status of file 3 is "sending", and the sending status of file 4 and file 5 is "waiting to send".

Optionally, in this embodiment of the present invention, the absolute path of the file may be used to identify the file.

Further, step 207 can be specifically implemented by step 207b:

Step 207b: The sending device displays the sending status of a file on the current interface of the sending device according to the corresponding relationship.

It can be understood from Table 1 that before the user of the sending device determines to send, file 1 and file 2 have been sent, file 3 is being sent, and file 4 and file 5 are waiting to be sent. The sending device can display the sending status of the five files on the display interface of the intended device according to the current information in Table 1.

Based on this solution, after the sending device acquires the user's selection operation on a file, it can display the file's status on the current interface of the sending device according to the corresponding relationship between the identifier of the file saved in the sending device, the sending state of the file, and the display state of the file. send status.

Optionally, the sending device deletes the corresponding relationship after acquiring the user's cancellation operation on a file.

Based on this solution, after acquiring the user's cancellation operation on a file, the sending device deletes the corresponding relationship corresponding to the file, and can release the storage space occupied by the corresponding relationship in real time.

Optionally, the sending device deletes the corresponding relationship after determining that the sending of all files is completed.
