Fig. 3 is a flowchart illustrating a file transfer method according to another exemplary embodiment, which is illustrated in the embodiment of the sending device 140 in the implementation environment shown in fig. 1. The file transmission method can comprise the following steps:

in step 302, the file is transmitted to the router via the intranet after being accessed to the intranet by the router.

In step 304, the receiving device corresponding to the file is indicated to a router, and the router is configured to send the file to the receiving device when the receiving device accesses the intranet.

and sending a target device identification to the router, wherein the target device identification is used for indicating the receiving device corresponding to the file.

In summary, in the file transmission method provided in this embodiment, when a sending device transmits a file to a receiving device in an intranet, the sending device sends the file to a router, and sends the file to the receiving device through the router when the receiving device accesses the intranet; the problems of low transmission efficiency, poor stability and no support for off-line transmission when the files are transmitted between the devices by point-to-point short-distance wireless transmission technologies such as Bluetooth, NFC and ZigBee in the related technology are solved; on one hand, compared with the wireless network connections, the transmission speed and the stability of the wired network connection or the Wi-Fi connection established between the equipment and the router are improved; on the other hand, in the process of forwarding the file sent by the sending device in the intranet to the receiving device in the intranet by the router, because the router has the function of storing the file, the transmission process supports offline transmission, and the transmission of the file can be realized without limiting the simultaneous connection of the sending device and the receiving device to the router.

Fig. 4A is a flowchart illustrating a file transfer method according to another exemplary embodiment, which is illustrated in the implementation environment shown in fig. 1. The file transmission method can comprise the following steps:

in step 401, a sending device sends a file to a router, and the sending device accesses to an intranet through the router.

The sending device is connected with the router through a wireless network or a wired network. In this embodiment, a wireless network connection is established between the sending device and the router through the Wi-Fi network. When the sending equipment needs to transmit the file to the receiving equipment in the intranet, the sending equipment sends the file needing to be transmitted to the router through the Wi-Fi network connection.

Compared with point-to-point short-distance wireless transmission technologies such as Bluetooth, NFC and ZigBee, the transmission speed of Wi-Fi network connection can reach 54Mbps or even higher, and therefore the transmission speed of files can be greatly improved. In addition, the stability of Wi-Fi network connections is also better than the stability of several wireless network connections described above. Therefore, the file transmission method provided by the embodiment can realize efficient and stable file transmission in the intranet.

Optionally, a client corresponding to the router may be operated in the sending device. After the network connection is established between the sending equipment and the router, the sending party can log in the router through the client side, and sends files to the router through the client side after the logging is successful.

Accordingly, the router receives the file transmitted from the transmitting device in the intranet to the receiving device in the intranet.

In step 402, the router stores the file.

The router is provided with an external memory, and the external memory is used for storing files. Alternatively, the type of external memory includes, but is not limited to, hard disks, floppy disks, optical disks, U-disks, and the like. Taking the router as an example in which a hard disk is disposed, the type of the hard disk includes, but is not limited to, a solid state disk, a mechanical hard disk, a hybrid hard disk, and the like.

And after receiving the file sent by the sending equipment in the intranet to the receiving equipment in the intranet, the router stores the file in the external memory. Since the router stores the file in the external memory, the file can be saved in the router without being lost even if the router is powered off.

In addition, in addition to the above-mentioned several types of memories, the router may be provided with other types of memories, and this embodiment is not limited thereto.

In step 403, the sending device indicates to the router the receiving device to which the file corresponds.

As shown in fig. 4B, in one possible embodiment, this step may include the following sub-steps:

in step 403a, the router sends a device list containing at least one device identification to the sending device.

Wherein the at least one device identifier includes at least one of a device identifier corresponding to a device currently connected to the router and a device identifier corresponding to a device already connected to the router. That is, the router sends the device identifier of the online device and/or the offline device to the sending device. The device identification is used to distinguish between different devices. Alternatively, the device identification may be a MAC (Media Access Control) address.

Of course, in other possible embodiments, the device identifier may also be represented by one or more combinations of MAC address, user account corresponding to the device, user nickname corresponding to the device, and the like. This embodiment is not limited to this.

Accordingly, the transmitting device receives the device list transmitted by the router.

In step 403b, the transmitting device displays a list of devices.

The sending device displays the list of devices so that the user can select one or more devices from the list of devices as the receiving device of the file.

In step 403c, the transmitting device acquires a selection signal corresponding to the identification of the target device in the device list.

The number of the target device identifiers may be one, or may be two or more, which is not limited in this embodiment. The target device identifier is used for indicating the receiving device corresponding to the file.

In step 403d, the sending device sends the destination device identification to the router.

Correspondingly, the router receives the target device identifier sent by the sending device, and determines the device corresponding to the target device identifier as the receiving device.

Of course, the manner provided above for the sending device to indicate the receiving device corresponding to the file to the router is only exemplary, and the sending device may also adopt other possible embodiments to indicate the receiving device corresponding to the file to the router. For example, when sending a file to a router, a sending device sends the device identifier of a receiving device corresponding to the file at the same time. This embodiment is not limited to this.

The step 403 may be performed before the steps 401 and 402, after the steps 401 and 402, or simultaneously with the steps 401 and 402. This embodiment is not limited to this.

In addition, optionally, the router may further store file information corresponding to each file, where the file information includes a file path of the file in the router and a transmission path corresponding to the file. The transmission path includes a correspondence between the device identification of the transmitting device and the device identification of the receiving device.

In step 404, the router sends the file to the receiving device when the receiving device accesses the intranet.

And the router sends the file to the receiving equipment when the receiving equipment establishes wired network connection or Wi-Fi network connection with the router according to the receiving equipment indicated by the sending equipment.

As shown in fig. 4C, in one possible embodiment, this step may include the following sub-steps:

in step 404a, the router transmits a file reception notification to the receiving device when the receiving device accesses the intranet.

Alternatively, the file reception notification may carry information such as a file name of the file, a device identifier of the transmission device, and the like. After checking the file receiving notice, the receiver can decide whether to receive the file.

Accordingly, the reception apparatus receives the file reception notification transmitted by the router.

In step 404b, the reception apparatus transmits a file reception response corresponding to the file reception notification to the router.

When the receiving side decides to receive the file, the receiving device sends a file receiving response to the router, and the file receiving response is used for indicating the router to send the file to the receiving device.

Accordingly, the router receives a file reception response corresponding to the file reception notification sent by the reception device.

In step 404c, the router sends the file to the receiving device according to the file reception response.

And after receiving the file receiving response, the router indicates that the receiving party user agrees to receive the file, and the router sends the file to the receiving equipment through the wired network connection or the Wi-Fi network connection established between the router and the receiving equipment.

Of course, in other possible embodiments, when the receiving device accesses the intranet, the router may also directly send the file to the receiving device. This embodiment is not limited to this.

Optionally, a client corresponding to the router may also be operated in the receiving device, and after the network connection is established between the receiving device and the router, the receiving party may log in to the router through the client. Correspondingly, the router sends the file to the client after the client in the receiving device successfully logs in the router.

In this embodiment, when sending a file to a router, the sending device only needs to ensure that a network connection is established between the sending device and the router, and the receiving device corresponding to the file may be online or offline; similarly, when the router forwards a file to a receiving device in the intranet, it is only necessary to ensure that a network connection is established between the receiving device and the router, and a sending device corresponding to the file may be online or offline. Therefore, the file transmission method provided by this embodiment supports offline transmission, and it is not necessary to limit the sending device and the receiving device to be connected to the router at the same time to transmit the file.

In addition, the file transfer method provided by the embodiment can support a one-to-one transfer mode and can also support a one-to-many transfer mode. When a sender user needs to transmit the same file to a plurality of receiver users, the sender user only needs to upload the file to the router once without executing repeated operations such as equipment pairing, file transmission and the like, and the user experience is fully improved.

Fig. 5 is a flowchart illustrating a file transfer method according to another exemplary embodiment, which is illustrated in the embodiment of fig. 1. The file transmission method can comprise the following steps:

in step 501, a sending device slices a file to obtain at least two file slices.

In this embodiment, the sending device may slice the file for transmission to the receiving device in the intranet before transmitting the file to the router. The sending equipment slices the file to be sent to obtain at least two file slices. The sending device may equally divide the file into a number of file slices of the same size, or may non-equally divide the file. For example, when the size of a file is 120KB, the transmitting device may divide the file into one file slice of 50KB and another file slice of 70 KB.

In step 502, the sending device sends the at least two file slices to the router in parallel by at least two sending threads.

Wherein each send thread is used to send one file slice. Compared with the single-thread mode for transmitting the whole file, the multi-thread mode for transmitting the multiple file slices in parallel is adopted by the sending equipment, and the file transmission efficiency can be improved. For example, taking the above-described two file slices of 50KB and 70KB in size, respectively, as an example, the sending device sends the two file slices to the router in parallel by two threads.

In addition, for each file slice, the sending device sends the file identifier corresponding to the file to which the file slice belongs to the router at the same time. Alternatively, the file identification may be a hash value of the file.

Correspondingly, the router receives the file slices sent by the sending equipment in the intranet in parallel through at least two receiving threads; wherein each receiving thread is configured to receive a file slice.

In step 503, the router stores the file slice transmitted by the transmitting device in the intranet.

The router stores the received file slices in an external memory such as a hard disk.

In this embodiment, the sending device slices the file and transmits the sliced file to the router, so that the transmission process supports breakpoint resuming. In the process of transmitting the file slice to the router by the sending device, the midway transmission may be interrupted due to poor network conditions or interruption of the transmission by a user. And the router end records the corresponding relation between the position information of each completely received file slice and the file identification corresponding to the file to which the file slice belongs. The next time the same file is transmitted, the sending device performs the following step 504:

in step 504, the sending device sends a query receiving request carrying a file identifier corresponding to the file to the router.

The received query request is used for querying the position information of the file slice which is completely received by the router in the file.

Correspondingly, the router receives a receiving query request which is sent by the sending equipment and carries the file identifier.

In step 505, the router queries the file corresponding to the file identification for location information of the file slice that has been completely received.

And the router inquires and acquires the position information of the file slice which is completely received in the file corresponding to the file identification according to the pre-stored corresponding relation.

In step 506, the router transmits the location information to the transmitting device.

Accordingly, the transmitting device receives the location information transmitted by the router.

In step 507, the sending device sends the file slice that is not completely received by the router in the file to the router according to the location information.

And after receiving the position information fed back by the router, the sending equipment resends the file slices which are not received by the router in the file to the router according to the position information. For the file slice completely received by the router in the file, the sending device does not need to retransmit the part of the file slice.

Accordingly, the router receives the file slices which are not completely received in the file transmitted by the transmitting device according to the position information.

For example, it is assumed that the transmitting device has a transmission interruption in transmitting the above-described two file slices of 50KB and 70KB in size, respectively, to the router, wherein the file slice of 50KB in size has completed transmission and the file slice of 70KB in size has not completed transmission. The router feeds back the location information corresponding to the file slice of 50KB to the sending device according to the received query request. Accordingly, the transmitting device retransmits the above file slice of size 70KB to the router according to the position information, without retransmitting the file slice of size 50 KB.

In step 508, the router stores the file slices not completely received in the file.

When the router receives the file slice which is not completely received in the file, the router stores the part of the file slice and the file slice which is completely received before.

In other possible embodiments, the router may also feed back, to the sending device, location information of file slices that are not completely received in the file corresponding to the file identifier, and the sending device may also be capable of sending, to the router, file slices that are not completely received by the router in the file according to the location information. This embodiment is not limited to this.

In step 509, the sending device indicates to the router the receiving device to which the file corresponds.

In step 510, the router sends the file to the receiving device when the receiving device accesses the intranet.
