Fig. 3 is a flowchart of a file transmission method according to an embodiment of the present invention. Referring to fig. 3, the method includes:

step 301: when the first terminal and the second terminal are in the same local area network, the first terminal generates first audio information with specified frequency based on first connection establishment information, wherein the first connection establishment information comprises address information of the first terminal and port information of a first socket object created by the first terminal.

When the first terminal generates the first audio information of the designated frequency based on the first connection establishment information, the first terminal may directly convert the first connection establishment information into the first audio information of the designated frequency.

Optionally, in order to improve reliability of file transmission and avoid an error of the first audio information in the transmission process, when the first terminal generates the first audio information with the specified frequency based on the first connection establishment information, the first terminal may add specified header information and specified tail information to the first connection establishment information to obtain second connection establishment information; the second connection establishment information is converted into first audio information of a specified frequency.

It should be noted that, in the embodiment of the present invention, when adding the specified header information and the specified trailer information to the first connection establishment information, the specified header information may be added to the header of the first connection establishment information, and the specified trailer information may be added to the trailer of the first connection establishment information, which is not described in detail in the embodiment of the present invention. In addition, the specified header information and the specified trailer information are set in advance by the first terminal and the second terminal, which is not particularly limited in the embodiment of the present invention.

For example, the header information is specified as XY, the trailer information is specified as 00, and the first connection establishment information may be jiexie #211.144.172.14#2, and at this time, the specified header information and the specified trailer information are added to the first connection establishment information, resulting in that the second connection establishment information is XY jiexie #211.144.172.14# 200.

In addition, the address information of the first terminal may be an IP address of the first terminal, and may also be other addresses, which is not specifically limited in this embodiment of the present invention. Furthermore, the first Socket object may be a Socket, and the port information of the first Socket object may include a port number, configuration information of a port, and the like, which is not specifically limited in the embodiment of the present invention.

Further, in order to avoid a malicious party from sending a connection establishment request to the first terminal based on the first audio information broadcast by the first terminal, before the first terminal generates the first audio information with a specified frequency based on the first connection establishment information, the method further includes: and generating first connection establishment information according to the specified character string, the address information of the first terminal and the port information of the first socket object and the specified format.

The designated character string is preset between the first terminal and the second terminal, and the second terminal can recognize the first connection establishment information according to the designated character string. In addition, the designated format is also preset between the first terminal and the second terminal, and the designated format may include multiple formats, for example, a mode of sequentially connecting the address information of the first terminal, the port information of the first socket object, and the designated character string in series, a mode of reversely connecting the address information of the first terminal, the port information of the first socket object, and the designated character string in series, and the like.

For example, when the address information of the first terminal is 211.144.172.14, the port information of the first socket object is 2, the designated string is jiexie, and the designation rule is "address information of the designated string # first terminal # port information of the first socket object", the first connection establishment information is jiexie #211.144.172.14#2 is generated according to the designation rule based on the address information 211.144.172.14 of the first terminal, the port information 2 of the first socket object, and the designated string jiexie.

In addition, in the embodiment of the present invention, the address information of the first terminal and the port information of the first socket object may be composed of a string of letters, numbers, punctuation marks, and the like, for convenience of description, the letters, numbers, punctuation marks, and the like are collectively referred to as characters, and the first terminal may store a correspondence between the characters and frequencies in advance, where a frequency corresponding to each character is a designated frequency. Therefore, when the first terminal converts the first connection establishment information into the first audio information of the specified frequency or converts the second connection establishment information into the first audio information of the specified frequency, the first terminal may obtain the corresponding frequency from the correspondence between the character and the frequency based on the character included in the first connection establishment information, thereby generating the first audio information of the specified frequency and realizing the conversion of the first connection establishment information. Or, the first terminal may obtain a corresponding frequency from a correspondence between the character and the frequency based on the character included in the second connection establishment information, thereby generating the first audio information with the specified frequency and implementing the conversion of the second connection establishment information.

For example, in the correspondence between characters and frequencies stored in the first terminal, the frequency corresponding to character j is 10Hz, the frequency corresponding to character i is 15Hz, the frequency corresponding to character e is 11Hz, the frequency corresponding to character x is 25Hz, the frequency corresponding to character # is 20Hz, the frequency corresponding to character 2 is 14Hz, the frequency corresponding to character 1 is 5Hz, and the frequency corresponding to character is 40Hz, the frequency corresponding to character 4 is 33Hz, and the frequency corresponding to character 7 is 50 Hz. When the first terminal converts the first connection setup information into first audio information of a designated frequency, the first audio information may be 10Hz15Hz11 Hz14 Hz5Hz33 Hz40Hz5Hz50Hz14 Hz5Hz33Hz20Hz14 Hz.

In the embodiment of the invention, when the first terminal and the second terminal are in the same local area network and file transmission is carried out between the first terminal and the second terminal, the file transmission can be carried out through the local area network without an operator, so that the data traffic of a user is not wasted, the data traffic of payment is not involved, and the extra cost is avoided for the user. The two ways of enabling the first terminal and the second terminal to be in the same local area network may include:

in the first mode, the first terminal establishes wireless network connection with the designated access point based on the designated access point information. And the second terminal establishes wireless network connection with the specified access point based on the specified access point information.

Since the first terminal and the second terminal are connected to the same access point, that is, a designated access point, the designated access point may be an access point to which the first terminal is currently connected or to which the first terminal is to be connected, or the designated access point may be an access point to which the second terminal is currently connected or to which the second terminal is to be connected.

For the first mode, when the first terminal and the second terminal are connected to the same access point and use the wireless hotspot network at the same time and do not use data traffic, the first terminal and the second terminal are in the same local area network. When the first terminal and the second terminal do not adopt the wireless hotspot network but adopt the data traffic, the first terminal and the second terminal need to be in the same local area network in the following second mode.

And in the second mode, the wireless network connection with the second terminal is established, so that the first terminal and the second terminal are in the same local area network.

For the first way, the first terminal may set the first terminal to a wireless access point mode; generating second audio information of a designated frequency based on first access point information of the first terminal, wherein the first access point information at least comprises an access point identifier; the first terminal broadcasts the second audio information in the wireless access point mode. And when the second terminal receives second audio information of the specified frequency broadcasted by the first terminal in the wireless access point mode, sending a wireless network connection request to the first terminal based on the second audio information. And when the first terminal receives a wireless network connection request sent by the second terminal based on the second audio information, establishing wireless network connection between the first terminal and the second terminal, so that the first terminal and the second terminal are in the same local area network.

When the first terminal generates the second audio information of the designated frequency based on the first access point information of the first terminal, the first terminal may directly convert the first access point information of the first terminal into the second audio information of the designated frequency. Accordingly, when the second terminal receives second audio information of a designated frequency broadcast by the first terminal in the wireless access point mode, the second terminal transmits a wireless network connection request to the first terminal based on the second audio information, including: the second terminal analyzes the second audio information to obtain first access point information, and sends a wireless network connection request to the first terminal based on the first access point information.

Optionally, in order to improve the reliability of file transmission and avoid an error in the transmission process of the second audio information, the generating, by the first terminal, the second audio information with a specified frequency based on the first access point information of the first terminal includes: the first terminal adds appointed head information and appointed tail information to first access point information of the first terminal to obtain second access point information; the second access point information is converted into second audio information of a specified frequency. Accordingly, when the second terminal receives second audio information of a designated frequency broadcast by the first terminal in the wireless access point mode, the second terminal transmits a wireless network connection request to the first terminal based on the second audio information, including: the second terminal analyzes the second audio information to obtain second access point information; performing fault tolerance verification on the second access point information based on the head information and the tail information of the second access point information; if the verification is passed, removing the head information and the tail information of the second access point information to obtain first access point information of the first terminal; and sending a wireless network connection request to the first terminal based on the first access point information.

It should be noted that, in the embodiment of the present invention, when adding the specified header information and the specified trailer information to the first access point information, the specified header information may be added to the header of the first access point information, and the specified trailer information may be added to the trailer of the first access point information, which is not described in detail in the embodiment of the present invention.

For example, the first access point information includes an access point identifier myssid, and at this time, the specified header information and the specified trailer information are added to the first access point information, resulting in that the second access point information is XYmyssid 00. According to the method of the above example, the second audio information to convert the second access point information into the specified frequency is 30Hz35Hz22 Hz28Hz15Hz45Hz8 Hz. Correspondingly, when the second terminal receives second audio information of the specified frequency broadcasted by the first terminal in the wireless access point mode, the second terminal analyzes the second audio information to obtain that the second access point information is XYmyssid 00; performing fault tolerance verification on the second access point information based on the head information XY and the tail information 00 of the second access point information; if the verification is passed, removing the head information XY and the tail information 00 of the second access point information to obtain the myssid of the first access point information of the first terminal; and sending a wireless network connection request to the first terminal based on the first access point information.

The second terminal performs fault-tolerant verification on the second access point information based on the header information and the tail information of the second access point information, and the fault-tolerant verification includes: the second terminal acquires the head information and the tail information of the second access point information; and if the acquired head information is the specified head information and the acquired tail information is the specified tail information, determining that the second access point information passes verification, otherwise, determining that the second access point information fails verification.

Further, the first terminal may periodically broadcast the second audio information, when the second terminal determines that the second access point information is verified in the current period, it is determined that no error occurs in the second audio information in the transmission process, it is determined that the second audio information is accurate, and a wireless network connection is established with the first terminal in the current period. And when the second terminal determines that the second access point information is not verified in the current period, determining that the second audio information has errors in the transmission process and is inaccurate, receiving the second audio information again when the second audio information is broadcast in the next period of the first terminal, and establishing wireless network connection with the first terminal according to the method.

In addition, in the embodiment of the present invention, each of the first access point information and the second access point information may be composed of a string of letters, numbers, punctuation marks, and the like, for convenience of description, the letters, numbers, punctuation marks, and the like are collectively referred to as characters, and the first terminal may store a correspondence between the characters and frequencies in advance, where a frequency corresponding to each character is a designated frequency. Therefore, when the first terminal converts the first access point information into the second audio information of the specified frequency, the first terminal may obtain the corresponding frequency from the corresponding relationship between the character and the frequency based on the character included in the first access point information, thereby generating the second audio information of the specified frequency, and implementing the conversion of the first access point information. Correspondingly, the corresponding relationship between the character and the frequency may also be stored in the second terminal, and when the second terminal analyzes the second audio information, the corresponding character may be acquired from the corresponding relationship between the character and the frequency based on the frequency included in the second audio information, so as to obtain the first access point information, and implement the analysis of the second audio information.

Or, when the first terminal converts the second access point information into the second audio information with the specified frequency, the first terminal may obtain the corresponding frequency from the corresponding relationship between the character and the frequency based on the character included in the second access point information, so as to generate the second audio information with the specified frequency, and implement the conversion of the second access point information. Correspondingly, when the second terminal analyzes the second audio information, the corresponding character can be obtained from the corresponding relationship between the character and the frequency based on the frequency included in the second audio information, so that the second access point information is obtained, and the second audio information is analyzed.

Furthermore, the first access point information may include not only the access point identifier but also information such as an access point password. When the first access point information includes the access point identifier, the second terminal may send the wireless network connection request to the first terminal directly based on the access point identifier when the second terminal sends the wireless network connection request to the first terminal based on the first access point information. When the first access point information further includes an access point password, before the first terminal generates the second audio information with the specified frequency based on the first access point information, the method further includes: and the first terminal generates first access point information according to the specified character string, the access point identifier and the access point password and the specified format. Correspondingly, when the second terminal sends the wireless network connection request to the first terminal based on the first access point information, the second terminal can analyze the first access point information according to the specified format to obtain an access point identifier and an access point password, and send the wireless network connection request to the first terminal based on the access point identifier and the access point password.

For example, the first access point information includes not only the access point identifier myssid but also the access point password mime 2233, the designated string is jisiexie, and the designated rule is "designated string # access point identifier # access point password", and at this time, according to the access point identifier myssid, the access point password mime 2233, and the designated string jisiexie, the first access point information is jisiexie # myssid # mime 2233 is generated according to the designated rule. Accordingly, when the second terminal sends the wireless network connection request to the first terminal based on the first access point information jiexie # myssima # mimea 2233, the second terminal may parse the first access point information jiexie # myssima # mimea 2233 according to a specified format to obtain the access point identifier myssid and the access point password mimea 2233, and send the wireless network connection request to the first terminal based on the access point identifier myssid and the access point password mimea 2233.

In the embodiment of the invention, when the first terminal is set to be in an Access Point (AP) mode, the first terminal can be used as a core of a wireless hotspot network and broadcasts the second audio information. Optionally, a general terminal may include a function of a wireless hotspot, so in the embodiment of the present invention, a user may set the first terminal in a wireless hotspot mode by starting the function of the wireless hotspot carried by the first terminal.

In addition, the Wireless hotspot network may be a WIFI (Wireless Fidelity) network, and of course, may also be other networks as long as the network does not need data traffic, and the embodiment of the present invention is not limited to this specifically. Furthermore, the access point Identifier may be an SSID (Service Set Identifier), the access point Identifier may be a name of the access point, a factory number of the access point, and the like, and the access point Identifier and the access point password may be Set in the first terminal by the user in advance, or may be Set by default by the first terminal.

It should be noted that the wireless network connection request sent by the second terminal to the first terminal may carry address information of the second terminal, and the like, which is not specifically limited in this embodiment of the present invention. In addition, the data traffic involved in the embodiment of the present invention is data traffic generated by accessing the internet through a mobile communication technology, and when the terminal uses the data traffic, a certain fee needs to be paid to an operator to which the data traffic belongs. In practical application, a user can purchase a package of data traffic, when the terminal uses the data traffic in the package, no extra fee is generated for the user, and when the used data traffic exceeds the data traffic in the package, the user needs to pay the extra fee. Therefore, the method provided by the embodiment of the invention can not consume the data flow of the user, thereby avoiding generating extra cost for the user.

Step 302: the first terminal broadcasts first audio information through the local area network.

Specifically, the first terminal may periodically broadcast the first audio information through the local area network. For example, the first terminal may broadcast the first audio information every 5 seconds.

Step 303: and when the second terminal receives first audio information of the designated frequency broadcasted by the first terminal through the local area network, sending a connection establishment request to the first terminal based on the first audio information.

In a scenario where the first audio information is obtained by directly converting the first connection establishment information by the first terminal, when the second terminal receives the first audio information of the specified frequency broadcasted by the first terminal through the local area network, the first audio information may be analyzed to obtain the first connection establishment information. And sending a connection establishment request to the first terminal based on the first connection establishment information.

Under the scene that the first audio information is obtained by converting the second connection establishment information by the first terminal, when the second terminal receives the first audio information with the appointed frequency broadcasted by the first terminal through the local area network, the first audio information can be analyzed to obtain the second connection establishment information; performing fault tolerance verification on the second connection establishment information based on the head information and the tail information of the second connection establishment information; if the verification is passed, removing the head information and the tail information of the second connection establishment information to obtain first connection establishment information; and sending a connection establishment request to the first terminal based on the first connection establishment information.

For example, the first audio information may be 10Hz15Hz11Hz25Hz15Hz11Hz20Hz14 Hz5Hz40Hz5Hz33 Hz40Hz5Hz50Hz14 Hz5Hz33Hz20Hz14Hz, and the first audio information is analyzed according to the corresponding relationship between characters and frequencies to obtain second connection establishment information XY jiexie #211.144.172.14# 200; performing fault tolerance verification on the second connection establishment information based on the head information XY and the tail information 00 of the second connection establishment information; if the verification is passed, removing the head information XY and the tail information 00 of the second connection establishment information to obtain first connection establishment information jiexie #211.144.172.14# 2; and sending a connection establishment request to the first terminal based on the first connection establishment information.

The second terminal performs fault-tolerant verification on the second connection establishment information based on the head information and the tail information of the second connection establishment information, and the fault-tolerant verification includes: acquiring head information and tail information of second connection establishment information; and if the acquired head information is the specified head information and the acquired tail information is the specified tail information, determining that the second connection establishment information is verified to be passed, otherwise, determining that the second connection establishment information is not verified to be passed.

Further, when the second terminal determines that the second connection establishment information is verified, it is determined that the first audio information is free of errors in the transmission process, it is determined that the first audio information is accurate, and the second terminal can remove the header information and the tail information of the second connection establishment information in the current period to obtain the first connection establishment information, so that a connection establishment request is sent to the first terminal. And when the second terminal determines that the second connection establishment information is not verified, determining that the first audio information has errors in the transmission process, determining that the first audio information is inaccurate, receiving the first audio information again when the first audio information is broadcast in the next period of the first terminal, and sending a connection establishment request to the first terminal according to the method.

Further, when the first connection establishment information is generated by the first terminal according to the specified character string, the address information of the first terminal, and the port information of the first socket object in the specified format, the second terminal sends a connection establishment request to the first terminal based on the first connection establishment information, including: analyzing the first connection establishment information according to a specified format to obtain address information of the first terminal and port information of the first socket object; and sending a connection establishment request to the first terminal based on the address information of the first terminal and the port information of the first socket object.

For example, if the first connection establishment information is generated by the first terminal according to the specified character string, the address information of the first terminal, and the port information of the first socket object in the specified format, the second terminal parses the first connection establishment information jiexie #211.144.172.14#2 in the specified format, and obtains that the address information of the first terminal is 211.144.172.14 and the port information of the first socket object is 2; and sending a connection establishment request to the first terminal based on the address information of the first terminal and the port information of the first socket object.

Therefore, when the second terminal analyzes the first audio information, the corresponding characters can be obtained from the corresponding relation between the characters and the frequencies based on the frequencies included in the first audio information, so that the first connection establishment information or the second connection establishment information is obtained, and the first audio information is analyzed.

It should be noted that the connection establishment request sent by the second terminal to the first terminal may carry port information of the second socket object created by the second terminal, address information of the second terminal, and the like, which is not specifically limited in this embodiment of the present invention.

Step 304: and when the first terminal receives a connection establishment request sent by the second terminal based on the first audio information, establishing a connection between the first socket object and a second socket object established by the second terminal.

In the embodiment of the present invention, a method for establishing a connection between a first socket object and a second socket object established by a second terminal by a first terminal may refer to an existing method, which is not described in detail in the embodiment of the present invention.

Step 305: and the first terminal performs file transmission with the second terminal through the connection between the first socket object and the second socket object.

The first terminal transmits the file with the second terminal through the connection between the first socket object and the second socket object without passing through an operator, so that the data traffic of the user is saved, and further, the extra cost generated for the user is avoided.

It should be noted that, in this embodiment of the present invention, the time when the first terminal creates the first socket object may be after a wireless network connection is established with the second terminal and before the first audio information with a specified frequency is generated based on the first connection establishment information, and the time when the second terminal creates the second socket object may be before a connection establishment request is sent to the first terminal based on the first audio information, which is not specifically limited in this embodiment of the present invention. In addition, after the first terminal creates the first socket object, the first terminal may acquire the port information of the first socket. After the second terminal creates the second socket object, the second terminal may acquire the port information of the second socket.

In the embodiment of the invention, when the first terminal and the second terminal are in the same local area network, the first terminal generates the first audio information with the appointed frequency based on the first connection establishment information, and broadcasts the first audio information through the local area network, so that the second terminal receives the first audio information. And through the local area network, the time for broadcasting the first audio information is short, the speed is high, so that the second terminal can also quickly receive the first audio information, the connection between the first socket object of the first terminal and the second socket object of the second terminal can be quickly established, and the file transmission efficiency is improved. In addition, the first terminal adds the specified header information and the specified trailer information to the first connection establishment information to obtain second connection establishment information, and converts the second connection establishment information into first audio information of specified frequency. When the second terminal receives the first audio information, the first audio information is analyzed to obtain second connection establishment information, and whether errors occur in the transmission process of the first audio information is judged according to the head information and the tail information of the second connection establishment information, so that the reliability of file transmission is improved.
