Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a schematic diagram illustrating an implementation environment related to a file transfer method according to some exemplary embodiments, and as shown in fig. 1, the implementation environment may include a first terminal 110 and a second terminal 120

The first terminal 110 and the second terminal 120 are in the same local area network.

The first terminal 110 and the second terminal 120 both support a WIFI system, that is, both can communicate through WIFI.

The first terminal 110 and the second terminal 120 both support NFC communication or both support bluetooth communication.

The first terminal 110 and the second terminal 120 may be a smart phone, a tablet computer, a desktop computer with a wireless function, a multimedia playing device, and the like.

Fig. 2 is a flowchart illustrating a file transfer method according to an exemplary embodiment, where the file transfer method is illustrated in fig. 2 and applied to the first terminal 110 in the implementation environment shown in fig. 1, and the file transfer method includes the following steps.

In step 201, the first terminal acquires a frequency band supported by the first terminal.

In step 202, the first terminal acquires a frequency band supported by the second terminal.

In step 203, when the frequency band supported by the first terminal and the frequency band supported by the second terminal both include 5GHz, the first terminal interacts with the second terminal on the frequency band of 5GHz to send a file.

In summary, according to the file transmission method provided in the embodiment of the present disclosure, when the first terminal and the second terminal both support 5GHz, file transmission is performed on a 5GHz frequency band, and since a file can be transmitted on a higher 5GHz frequency band commonly supported by the first terminal and the second terminal, a technical problem of insufficient function utilization caused by directly performing file transmission on a 2.4GHz frequency band is solved; the technical effect of fully utilizing a higher frequency band to improve the file transmission efficiency is achieved.

In practical application, when a file is transmitted between a first terminal and a second terminal, at least one end of the first terminal or the second terminal may not support a 5GHz frequency band, and at the moment, the first terminal and the second terminal can only transmit the file in a 2.4GHz frequency band; only when the first terminal and the second terminal both support the 5GHz band, the first terminal and the second terminal can transmit the file on the 5GHz band, and in actual implementation, the steps shown in fig. 3A may be referred to.

Fig. 3A is a flowchart illustrating a file transfer method according to another exemplary embodiment, and as shown in fig. 3A, the file transfer method is applied to the first terminal 110 in the implementation environment shown in fig. 1 for example, and the file transfer method includes the following steps.

In step 301, the first terminal acquires a frequency band supported by the first terminal.

When file transmission is performed, a first terminal first determines a frequency band supported by the first terminal, generally speaking, the frequency band supported by the first terminal is set inside the first terminal when the first terminal leaves a factory, and the first terminal can directly read the frequency band supported by the first terminal.

The existing market generally includes a terminal supporting a 2.4GHz band and a terminal supporting a 5GHz band, generally speaking, a terminal supporting a 2.4GHz band generally refers to a terminal supporting a 2.4GHz band but not supporting a 5GHz band, and a terminal supporting a 5GHz band generally refers to a terminal supporting a 2.4GHz band and a 5GHz band.

When the terminal supports the frequency band of 5GHz, the rate of file transmission by the terminal through the frequency band of 5GHz is higher than the rate of file transmission through the frequency band of 2.4 GHz.

In step 302, a first terminal acquires a frequency band supported by a second terminal.

When file transmission is performed, the first terminal needs to acquire not only a frequency band supported by the first terminal but also a frequency band supported by the second terminal, so as to select a more appropriate frequency band to implement file transmission with the second terminal.

Similarly, the frequency band supported by the second terminal is set inside the second terminal when leaving the factory, in this embodiment, the first terminal needs to acquire the frequency band supported by the second terminal, in a possible implementation, the first terminal and the second terminal both support NFC communication, and when the first terminal acquires the frequency band supported by the second terminal, refer to the steps shown in fig. 3B:

in step 302a, the second terminal acquires a frequency band supported by the second terminal.

Because the frequency band supported by the second terminal is set in the second terminal when leaving the factory, the second terminal can directly read the frequency band supported by itself.

In step 302b, the second terminal enters a passive mode in an NFC system, starts a radio frequency field, and transmits a frequency band supported by the second terminal by using the radio frequency field.

Generally, a transmitting end which needs to transmit information by using NFC is usually configured in a passive mode, and provides a radio frequency field in the passive mode, and transmits information to a receiving end which is in the active mode and receives information by using NFC, and after the receiving end enters the radio frequency field, the receiving end can identify the information transmitted by the transmitting end. Therefore, the second terminal serving as the transmitting end needs to provide a radio frequency field in the passive mode, and transmit the frequency band supported by the second terminal to the first terminal serving as the receiving end through the radio frequency field.

In step 302c, the first terminal receives a frequency band supported by the second terminal and transmitted by the second terminal through the radio frequency field.

After entering the radio frequency field provided by the second terminal, the first terminal may identify information sent by the second terminal in the radio frequency field, for example, a frequency band supported by the second terminal and sent by the second terminal.

In another possible implementation, both the first terminal and the second terminal support bluetooth communication, and when the first terminal acquires a frequency band supported by the second terminal, the first terminal establishes a bluetooth connection with the second terminal, and receives the frequency band supported by the second terminal, which is sent by the second terminal through the bluetooth connection.

The bluetooth is a short-distance wireless communication technology, and devices for bluetooth communication are also generally divided into an active mode and a passive mode, generally speaking, a transmitting end which needs to transmit information by using bluetooth and a receiving end which needs to receive information by using bluetooth are not allocated in a so-called master-slave mode, but a terminal in the active mode needs to actively search for a terminal in the passive mode and initiate bluetooth pairing to the terminal in the passive mode to complete bluetooth connection, and the transmitting end and the receiving end can transmit information to each other by using bluetooth on the basis of establishing bluetooth connection. Therefore, on the premise that the first terminal serving as the receiving end and the second terminal serving as the sending end are in a master-slave mode, after the two terminals complete Bluetooth pairing and establish Bluetooth connection, the first terminal receives the frequency band supported by the second terminal sent by the second terminal through Bluetooth.

In step 303a, when the frequency band supported by the first terminal and the frequency band supported by the second terminal both include 5GHz, the first terminal interacts with the second terminal on the frequency band of 5GHz to send a file.

When the frequency band supported by the first terminal and the frequency band supported by the second terminal both include 5GHz, it indicates that both the first terminal and the second terminal can operate in the 5GHz frequency band, and in order to transmit a file at a higher speed, the first terminal may select a file to be transmitted in interaction with the second terminal on the 5GHz frequency band, and in implementation, refer to the steps shown in fig. 3C:

when the first terminal is a sending terminal and the second terminal is a receiving terminal:

in step 303aa, the first terminal accesses a WIFI hotspot of a 5GHz frequency band started by the second terminal.

The second terminal starts the WIFI hotspot when the first terminal and the second terminal are judged to support the 5GHz frequency band, and correspondingly, the first terminal can access the WIFI hotspot of the 5GHz frequency band started by the second terminal.

In step 303ab, the first terminal sends the file to be transmitted to the second terminal.

When the first terminal is a receiving terminal and the second terminal is a sending terminal:

in step 303ac, the first terminal starts a WIFI hotspot in the 5GHz frequency band.

After the first terminal starts the WIFI hotspot of the 5GHz frequency band, the second terminal can access the WIFI hotspot of the 5GHz frequency band, and after the WIFI hotspot of the 5GHz frequency band is accessed, the file can be sent to the first terminal.

In step 303ad, the first terminal receives a file sent by the second terminal after accessing the WIFI hotspot.

When the first terminal needs to receive the file sent by the second terminal and the first terminal judges that the first terminal and the second terminal both support the 5Hz frequency band, the first terminal starts the 5GHz frequency band WIFI hotspot, so that the second terminal can access the WIFI hotspot and sends the file to the accessed WIFI hotspot, and correspondingly, the first terminal receives the file sent by the second terminal through the WIFI hotspot.

In step 303b, when at least one of the frequency bands supported by the first terminal and the frequency band supported by the second terminal does not contain 5GHz, the first terminal and the second terminal interactively transmit a file on the frequency band of 2.4 GHz.

When at least one of the frequency bands supported by the first terminal and the second terminal does not contain 5GHz, it indicates that the first terminal and the second terminal cannot transmit the file on the 5GHz frequency band at the same time, and therefore, in order to ensure the file transmission, the first terminal may select the file interactively transmitted with the second terminal on the 2.4GHz frequency band.

To sum up, according to the file transmission method provided by the embodiment of the present disclosure, when the first terminal and the second terminal both support 5GHz, file transmission is performed on a 5GHz frequency band, and since a file can be transmitted on a higher 5GHz frequency band commonly supported by the first terminal and the second terminal, a technical problem of insufficient function utilization caused by directly performing file transmission on a 2.4GHz frequency band is solved; the technical effect of fully utilizing a higher frequency band to improve the file transmission efficiency is achieved.

In addition, when at least one of the first terminal and the second terminal is determined not to support the 5GHz frequency band, file transmission is carried out on the 2.4GHz frequency band, and effective transmission of files is guaranteed.

By providing two frequency band acquisition methods for the first terminal, the problem that the first terminal cannot acquire the frequency band supported by the second terminal under the condition that the first terminal or the second terminal does not support NFC or Bluetooth is avoided.

Meanwhile, no matter the first terminal is a receiving end or a sending end, as long as the first terminal and the second terminal both support the 5GHz frequency band, the first terminal and the second terminal can transmit files on the 5GHz frequency band, the problem that the first terminal can only transmit the files on the 5GHz frequency band by the sending end or the receiving end is solved, and objective conditions for transmitting the files by using the 5GHz frequency band are reduced.

It should be added that, in the foregoing embodiment, the judgment is performed at the first terminal, and similarly, when the second terminal judges that the selectable networking system is used for communicating with the first terminal, the second terminal needs to acquire a frequency band supported by the first terminal in addition to the frequency band supported by the second terminal, at this time, if the first terminal and the second terminal communicate through NFC connection, the first terminal puts the first terminal in a passive mode, and transmits the frequency band supported by the first terminal to the second terminal by using a radio frequency field provided by the second terminal, and the first terminal; if the first terminal and the second terminal communicate through the Bluetooth connection, the first terminal firstly establishes the Bluetooth connection with the second terminal, and transmits the frequency band supported by the first terminal to the second terminal by using the Bluetooth connection.

In actual implementation, the first terminal and the second terminal both need to determine frequency bands which can be supported by the first terminal and the second terminal, and determine a WIFI system which needs to be started for transmitting files according to a determination result.

In step 314, when the first terminal and the second terminal both support the 5GHz band, the second terminal starts a WIFI hotspot of the 5GHz band.

In step 315, the first terminal connects to a WIFI hotspot of a 5GHz frequency band started by the second terminal.
