Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before explaining the embodiments of the present invention in detail, an application scenario of the embodiments of the present invention will be described.

In daily life, people who need to participate in certain activities or have certain relationships are often pulled into a group in instant messaging software, so that the people can negotiate certain problems in the group together or share certain viewpoints or information.

In the current group establishment mode, the group owner is relied on to invite the group members one by one or the group members are relied on to join one by one, so that the operation is complicated, the interference is easy to happen, the group establishment time is long, the group establishment efficiency is low, and the rapid group establishment requirement that the group owner pulls the related members into the group cannot be met.

For example, when group members scan codes into a group, if there are many group members, it is necessary to queue each group member to scan codes into a group, which takes a long time. For another example, when group members enter a group according to group data notified by the group owner, the group owner is required to notify each group member of the group data one by one, which is time consuming, and in a noisy environment, the group members easily receive wrong group data, resulting in group entry failure. For another example, when the group members enter the group according to the invitation of the group owner, the group owner needs to send the invitation to each group member one by one through the terminal operation, which is also time consuming.

In order to solve the problems of long group building time and low group building efficiency in the related art and meet the requirement of fast group building that after a group owner establishes a group, the group owner can pull related members into the group at the same time, the embodiment of the invention provides a group building method which can pull all the members in the nearby range into the group at the same time by playing sound.

The clustering method provided by the embodiment of the invention is mainly applied to a scene of clustering in an open occasion in a nearby range. For example, a player group is quickly established on a football stadium, or a participant group is quickly established in a meeting room, or a party group is quickly established on a dining table, at a family party, etc.

The system architecture of the embodiments of the present invention is described next.

Fig. 1B is a schematic diagram of a group establishment system according to an embodiment of the present invention, as shown in fig. 1B, the group establishment system includes a first terminal 10 and a second terminal 20. The first terminal 10 is a terminal used by a group owner, and the second terminal 20 is a terminal used by a group member.

It should be noted that the group establishment system may include one second terminal 20, or may include a plurality of second terminals 20, and fig. 1B only illustrates that the group establishment system includes a plurality of second terminals 20 as an example.

The first terminal 10 is configured to, when detecting a group establishment operation, establish a group and acquire group data, where the group data includes a group identifier and a group entry password of the group; converting the group data into audio data; and playing the audio data, wherein the audio data is used for indicating a second terminal which acquires the audio data to convert the audio data into group data, and joining the group according to a group identifier and a group entering password which are included in the group data.

Wherein, the second terminal 20 is used for obtaining audio data; and when the audio data is converted to obtain group data, adding the group indicated by the group identifier according to the group identifier and the group entering password included in the group data.

In practical applications, the first terminal 10 and the second terminal 20 may be specifically terminals such as a mobile phone, a tablet computer, and a wearable device, which is not limited in the embodiment of the present invention.

Further, the clustering system further comprises a server 30, and the server 30 may be a background server for maintaining the group. Taking the example of the clustering system establishing a group based on an instant messaging application, the server 30 may be a background server of the instant messaging application.

In the process of establishing a group and acquiring group data by the first terminal 10, the first terminal 10 may generate group data according to the group establishing operation, and then send the group data to the server 30, and the server 30 establishes the group according to the group data. Alternatively, the first terminal 10 may send a group request to the server 30 according to a group operation, the server 30 generates group data based on the group request, establishes a group according to the group data, and sends the group data to the first terminal 10.

In the process that the second terminal 20 joins the group according to the group identifier and the group entering password, the second terminal 20 may first obtain the user identifier currently logged in by the second terminal 20, and then send a group entering request to the server 30, where the group entering request carries the user identifier, the group identifier, and the group entering password, and the server 30 adds the user identifier to the group according to the group identifier and the group entering password.

For example, fig. 1C is a schematic diagram of another group building system provided in an embodiment of the present invention, where the group building system includes a first terminal 10, a plurality of second terminals 20, and a server 30, and based on the group building system, the embodiment of the present invention may complete the group building operation through the following steps 1) to 5):

1) the first terminal 10 generates group data according to the group establishment operation of the group owner and uploads the group data to the server 30, and the server 30 establishes a group according to the group data. The group data comprises a group identification and a group entering password of the group.

2) The first terminal 10 transmits the group data to the second terminal 20 within range of the accessory by voice.

3) The second terminal 20 sends a group entry request to the server 30 according to the group data received by voice, where the group entry request carries the user identifier, the group identifier, and the group entry password logged in by the second terminal 20.

4) The server 30 transmits a group success message to the second terminal 20 after successfully adding the user id to the group according to the group id and the group entry password.

5) The server 30 sends a notification message to the first terminal 20, the notification message being used to notify the subscriber identity to join the group, i.e. to notify the group members of successful group joining.

It should be noted that, in the embodiment of the present invention, the group building operation is completed through the above steps 1) to 5) based on the group building system shown in fig. 1C, and it can be understood in the art that the above steps 1) to 5) do not limit the group building method provided in the embodiment of the present invention.

The clustering method provided by the embodiment of the invention will be described in detail below.

Fig. 1D is a flowchart of a clustering method according to an embodiment of the present invention, which can be applied to the clustering system shown in fig. 1B or fig. 1C, as shown in fig. 1D, the method includes the following steps:

step 101, when detecting a group establishing operation, a first terminal establishes a group and acquires group data, wherein the group data comprises a group identification and a group entering password of the group.

The first terminal is a terminal used by a group owner. The group establishment operation is used to instruct the first terminal to establish a group, and specifically may trigger an operation of a group establishment option for a group owner. The group option may be an icon or button, etc. For example, the group option may be a "quick pull" button that a group owner may trigger a group operation by clicking on.

Further, the group establishing operation may be implemented based on an installed instant messaging application, and the first terminal may establish a group and acquire group data when the group establishing operation is detected by the installed instant messaging application. In particular, the group operation may be an operation in which the group owner triggers a group option displayed in the instant messaging application.

The group identifier is used to uniquely identify the group, and may specifically be a group name or a group ID (identification, account number). The group ID may consist of letters, numbers, or a combination of both.

The group entry password is a password for joining the group corresponding to the group, and may be referred to as a group entry password. In practical applications, a group entry password is usually set for a group when the group is established, so that group members join the group based on the group entry password. The group entering password is set for the group, so that the group management is convenient, the group security is ensured, and the group management confusion caused by that group members can randomly join any group is avoided.

The group-entering password and the group identifier can be generated independently, and the group-entering password can also be generated according to the group identifier. For example, in the case that the group entry password is generated according to the group ID, when the group ID is the group ID and the group ID is a number, the group entry password may be composed of the first M even-numbered digits of the group ID.

Wherein, M can be preset and is a positive integer. For example, M may be 3 or 4, etc. The group ID may be calculated from even bits 0 or odd bits 1, which is not limited in the embodiment of the present invention. When starting with even 0, the first digit of the group ID is located at even 0, the second digit is located at odd 1, and so on. When starting with odd digit 1, the first digit of the group ID is at odd digit 1, the second digit is at even digit 2, and so on.

Further, when the number of even digits of the group ID is less than M, after selecting the digits corresponding to all the even digits from the group ID, padding data may be added before the selected digits, so that the number of digits of the obtained group-entering password is equal to M. The padding data may be 0, or may be other preset numbers, which is not limited in this embodiment of the present invention.

For example, as shown in table 1 below, assuming that the group ID is 1234567, the group entry password consists of the first 4 even-numbered digits of the group ID, and the group ID is calculated from the even-numbered digits 0, the group entry password may consist of the digits 1 corresponding to the first even-numbered digit 0, the digits 3 corresponding to the second even-numbered digit 2, the digits 5 corresponding to the third even-numbered digit 4, and the digits 7 corresponding to the fourth even-numbered digit 6, i.e., the group entry password is 1357.

TABLE 1

It should be noted that, in the embodiment of the present invention, only the group ID and the group entry password shown in table 1 are taken as an example for description, but the group ID and the group entry password shown in table 1 do not limit the group data.

In practical applications, the group data may be generated by the first terminal or generated by the server. Specifically, the operation of establishing a group and acquiring group data may include the following two implementation manners:

the first implementation mode comprises the following steps: the first terminal generates group data according to the detected group establishing operation, then the group data is sent to the server, and the server establishes a group according to the group data.

In practical application, the first terminal may randomly generate group data according to a preset group data generation algorithm. After receiving the group data, the server may generate a group corresponding to the group identifier included in the group data.

Further, after receiving the group data, the server may further determine whether a group identifier included in the group data exists in the group identifier of the established group, that is, determine whether the group identifier is occupied by the established group; when the group mark does not exist in the group marks of the established groups, establishing the groups according to the group data; and when the group identifier exists in the group identifier of the established group, sending regeneration indication information to the first terminal, wherein the regeneration indication information is used for indicating the first terminal to regenerate the group data until the group identifier included in the generated group data does not exist in the group identifier of the established group, and establishing the group according to the group data.

When the group identification included in the group data does not exist in the group identification of the established group, the step of establishing the group according to the group data is executed, so that the generation of the group according to the occupied group identification can be avoided, and the newly established group and the established group can be clearly distinguished.

The second implementation mode comprises the following steps: sending a group building request to a server according to the group building operation, generating group data by the server based on the group building request, building a group according to the group data, and sending the group data to a first terminal; and receiving the group data sent by the server.

In a second manner, the first terminal may obtain the group data by receiving the group data sent by the server. After receiving the group establishment request, the server may generate group data according to the established group identifier, so that the generated group data includes a group identifier different from the established group identifier.

Step 102: the first terminal converts the group data into audio data.

In the embodiment of the present invention, in order to send the group data by voice, the first terminal may convert the group data into audio data.

Specifically, the operation of converting the group data into the audio data may include the following steps 1021-:

step 1021: and combining the group identification and the group entering password to obtain source code data.

The source code data refers to data obtained by combining the group identifier and the group entering password.

Specifically, the source code data may be obtained by adding the group entry password to the group identifier. For example, assuming the group id is 1234567 and the group entry password is 1357, the source code data may be 12345671357. Of course, the source code data may also be obtained by adding the group entry password to the group id. For example, assuming the group id is 1234567 and the group entry password is 1357, the source code data may be 13571234567. The embodiment of the present invention does not limit the combination manner of the source code data.

Step 1022: and carrying out Solomon coding on the source code data, and determining to obtain coded data according to a coding result.

By performing the solomon encoding on the source code data, the source code data can be encrypted to ensure the security and stability of the group data in the transmission process.

Specifically, when the group ID is the group ID and the source code data is the decimal data, performing solomon encoding on the source code data, and determining the encoded data according to the encoding result may include: converting the source code data into hexadecimal data; and carrying out Solomon coding on the hexadecimal data, and determining to obtain the coded data according to a coding result.

Since the solomon code is a hexadecimal code and each code word to be coded is a hexadecimal number, the source code data needs to be converted into hexadecimal data in the process of determining the coded data according to the source code data. Furthermore, in order to facilitate conversion of the source code data into hexadecimal data, the source code data may be set in advance as decimal data, i.e., Int (integer) type data. Specifically, the source code data may be guaranteed to be decimal data by setting the group identifier as the group ID and setting both the group ID and the group-in password as positive integers. By limiting the original data to decimal data, the success rate of sound wave transmission and identification can be greatly improved, and the complexity of the Solomon code is reduced.

Further, as the solomon code is a fixed-length code, that is, after the source code data is converted into hexadecimal data, the hexadecimal data with preset digits needs to be obtained, so performing the solomon code on the source code data, and determining to obtain the coded data according to the coding result may further include: when the digit of the hexadecimal data is equal to a preset digit, carrying out Solomon coding on the hexadecimal data, and determining to obtain the coded data according to a coding result; when the number of bits of the hexadecimal data is less than the preset number of bits, adding a specified number of filling data before the hexadecimal data to obtain the hexadecimal data with the preset number of bits; performing Solomon coding on the hexadecimal data with the preset digit, and determining to obtain the coded data according to a coding result, wherein the specified number is the difference between the preset digit and the digit of the hexadecimal data.

The padding data may be 0, and certainly may also be other preset data, which is not limited in this embodiment of the present invention. The preset number of digits may be set in advance, and since the number of digits of hexadecimal data obtained by converting decimal data is 8 at maximum, the preset number of digits may be set to 8.

For example, assuming that the predetermined number of bits is 8, the padding data is 0, and the hexadecimal data obtained after the decimal source code data is converted is 123ABCD, a 0 may be added before 123ABCD to obtain encoded data 0123 ABCD.

Specifically, performing solomon encoding on the hexadecimal data with the preset number of bits, and obtaining the encoded data according to the encoding result includes: performing Solomon coding on the hexadecimal data with the preset digit to obtain a redundant code; and adding the redundant code to the hexadecimal data with the preset digit to obtain the coded data. That is, the encoded data includes hexadecimal source code data and redundant codes.

It should be noted that the solomon code is a channel code for forward error correction, which is a technique for controlling transmission errors in a unidirectional communication system. In the process of the Solomon coding, redundancy of data to be coded can be obtained in a mode of solving redundancy at a plurality of points to obtain redundant codes, and then the redundant codes are transmitted or stored. When the receiver correctly receives enough points, the original data to be coded can be recovered through the directional processing of the Solomon code, namely the Solomon decoding.

Errors generated in the data transmission process can be recovered by carrying out the Solomon coding on the source code data, the error rate of the transmitted data is reduced, the finally obtained audio data is prevented from being interfered by external sound when being played, or the data transmission errors caused by equipment difference are prevented, the accuracy of data transmission is improved, and the success rate of data transmission is improved.

For example, referring to fig. 1E, assuming that the hexadecimal data with the preset number of bits is 0123ABCD, the 0123ABCD is encoded in a solomon encoding manner, and the obtained redundant code is FEDCBA9, FEDCBA9 may be added after 0123ABCD to obtain encoded data 0123ABCDFEDCBA9。

Referring to FIG. 1E, assume encoded data 0123ABCDFEDCBA9After transmission, 3-bit error codes are generated, and data received by a receiving end becomes 12CAB7DFEECBA9After the data received by the receiving end is subjected to the solomon decoding, the 12CAB7D can be usedFEECBA9Reducing to 0123 ABCDFADDCBA 9, so that the receiving end can obtain the correct processing result.

Step 1023: and determining sound frequency corresponding to each data in a plurality of data included in the coded data according to the corresponding relation between the stored data and the sound frequency.

That is, the encoded data may be converted into sound frequencies according to the correspondence between the stored data and the sound frequencies. The correspondence between the stored data and the sound frequency may be preset, and the sound frequency stored in the correspondence may be cut from a plurality of sound frequencies included in the treble table in advance.

In practical applications, the sound frequency stored in the correspondence relationship may be a sound frequency that can be heard by human ears, or a sound frequency that cannot be heard by human ears. At present, it is generally considered that the sound frequency that can be heard by human ears is 20-20KHz, when it is desired that the first terminal has a corresponding sound effect in the process of transmitting the group data by sound, the sound frequency stored in the corresponding relationship may be set between 20-20KHz, and when it is not desired that the first terminal has a corresponding sound effect in the process of transmitting the group data by sound, i.e. when it is desired that the first terminal transmits the group data in a mute manner (when the human ears cannot hear sound), the sound frequency stored in the corresponding relationship may be set above 20KHz or below 20 Hz.

Specifically, determining the sound frequency corresponding to each of the plurality of data included in the encoded data according to the stored correspondence relationship between the data and the sound frequency may include the following two implementations:

the first implementation mode comprises the following steps: if the corresponding relation between the stored data and the sound frequency comprises a plurality of first data and corresponding sound frequencies, and the plurality of first data are determined based on all the constituent data of the group identification and the group entering password, the sound frequency corresponding to the designated data is determined according to the plurality of first data and the corresponding sound frequencies, and the designated data is any one of the plurality of data included in the encoded data.

The plurality of first data may include data obtained by encoding all constituent data of the group identifier and the group entry password. For example, when the data obtained by encoding the source code data composed of the group identifier and the group entry password is hexadecimal data, the plurality of first data may include all the component data of the hexadecimal data, i.e., 16 data between 0 and F. Where 16 data between 0-F includes 10 numbers between 0-9 and 6 letters between A-F.

The sound frequencies corresponding to the plurality of first data may be preset, for example, may be obtained from a high-pitched sound chart. For example, 16 sound frequencies corresponding to (+1) - (+16) may be extracted from the high sound table shown in table 2 below as the sound frequencies corresponding to 16 data between 0 and F, respectively.

TABLE 2

In table 2, the unit of the sound frequency is Hz (hertz), and the content in parentheses after the sound frequency is used to indicate the semitone distance from the center C (261.63Hz) of the corresponding sound frequency.

After intercepting the 16 sound frequencies corresponding to (+1) - (+16) as the sound frequencies corresponding to the 16 data between 0 and F, respectively, the correspondence relationship between the stored data and the sound frequencies can be shown in table 3 below. Suppose the encoded data is 0123ABCDFEDCBA9，The audio frequency corresponding to each data in the encoded data can be found from table 3 below.

TABLE 3

First data	Frequency of sound	First data	Frequency of sound
				0	277.18	8	440.00
1	293.66	9	466.16
				2	311.13	A	493.88
3	329.63	B	523.25
				4	349.23	C	554.37
5	369.99	D	587.33
				6	392.00	E	622.25
7	415.30	F	659.26

It should be noted that, in the embodiment of the present invention, only the correspondence between the data and the sound frequency described in table 3 is taken as an example for description, but table 3 does not limit the embodiment of the present invention.

The second implementation mode comprises the following steps: if the corresponding relationship between the data and the sound frequency comprises a plurality of first data and corresponding sound frequencies, and a plurality of second data and corresponding sound frequencies, the sound frequencies corresponding to the second data are greater than the sound frequencies corresponding to the first data, the first data are determined based on all the component data of the group identification and the group entering password, the second data correspond to the first data one by one, the second data are obtained by respectively converting the first data, when the number of bits of the specified data in the coded data is a first number of bits, the sound frequency corresponding to the specified data is determined according to the first data and the corresponding sound frequencies, the specified data is any one of the data, and the first number of bits is an odd number or an even number; when the number of bits of the specified data in the coded data is a second number of bits, converting the specified data into second data according to the stored corresponding relation between the plurality of first data and the plurality of second data; determining a sound frequency corresponding to the second data according to the plurality of second data and the corresponding sound frequency; and determining the sound frequency corresponding to the second data as the sound frequency corresponding to the specified data, wherein the second number of bits is different from the first number of bits.

The plurality of first data may include data obtained by encoding all constituent data of the group identifier and the group entry password. For example, when the data obtained by encoding the source code data composed of the group identifier and the group entering password is hexadecimal data, the plurality of first data may include all the component data of the hexadecimal data, that is, the plurality of first data includes 16 data between 0 and F. Where 16 data between 0-F includes 10 numbers between 0-9 and 6 letters between A-F.

Wherein, the plurality of second data correspond to the plurality of first data one to one. For example, when the plurality of first data are 16 data between 0-F, the second data may be 16 data between G-V, and G-V corresponds to 0-F one to one. That is, the corresponding relationship may store 32 data items between 0 and V.

The sound frequencies corresponding to the plurality of first data and the plurality of second data may be preset, for example, may be obtained from a high-pitched sound chart. The sound frequencies corresponding to the first data are bass frequencies, and the frequencies corresponding to the second data are treble frequencies.

Step 1024: and performing audio conversion on the sound frequencies corresponding to the plurality of data to obtain the audio data.

In practical applications, a PCM (Pulse-code modulation) encoding method may be adopted to convert the audio frequencies corresponding to the plurality of data into PCM data corresponding to the plurality of data, respectively. The PCM sound data corresponding to each sound frequency is a segment of continuous sound. That is, by performing audio conversion on audio frequencies corresponding to a plurality of data, a plurality of point-like audio frequencies can be converted into continuous audio data.

Specifically, one data may be selected from the plurality of data, and the following processing may be performed on the selected data until each of the plurality of data is processed:

generating PCM audio data corresponding to the selected data according to the sound frequency corresponding to the selected data by the following formula:

wherein z is PCM audio data corresponding to the selected data, x is a preset number of samples, and the number of samples is greater than the number of samples_yAnd S is a preset sampling frequency and A is a preset parameter for the sound frequency corresponding to the selected data.

When the PCM audio data corresponding to the plurality of data is obtained through the above processing, the PCM audio data corresponding to the plurality of data may be sequentially combined to obtain the audio data.

The preset sampling frequency is the reciprocal of the preset number of samples, and the preset number of samples may be preset, for example, the preset number of samples may be 4000 or 4096.

When the preset number of samples is 4096, the preset sampling frequency is 44.1Hz, and the values of x are respectively 0 to 4095, that is, 4096 z values are respectively calculated for the sound frequency corresponding to each selected data according to the difference of the values of x, and the 4096 z values can constitute the audio data corresponding to the selected data.

In one possible implementation, the flow of converting the group data into the audio data may be as shown in fig. 1F. Firstly, hexadecimal conversion can be carried out on source code data to obtain hexadecimal data, wherein the source code data is composed of a group identifier and a group entering password; then, carrying out Solomon coding on the hexadecimal data to obtain coded data; then, carrying out audio conversion on the coded data to obtain audio data; and finally, playing the audio data to generate sound.

Step 103: the first terminal plays the audio data, and sends the group data to the second terminal through the played audio data.

The second terminal is a terminal used by the group member, is located around the first terminal, and can acquire the audio data played by the first terminal. The audio data is used for indicating a second terminal which acquires the audio data to convert the audio data into the group data, and the second terminal joins the group according to the group identification and the group entering password.

Specifically, the first terminal may transmit the audio data to music playing software for playing. The first terminal playing the audio data can generate sound, and the audio data is obtained by converting the group data, so that the group data can be sent to a second terminal nearby the first terminal through the sound. For example, by playing the audio data, a sound of a droplet of a specified duration may be emitted, and the second terminal may acquire the group data by listening to the sound of the droplet emitted by the first terminal.

It should be noted that the propagation form of sound is sound wave, so the clustering method provided by the embodiment of the present invention is a clustering method based on sound wave communication. With respect to the widespread use of infrared, bluetooth or NFC (Near Field Communication), acoustic Communication is often ignored by people, and in fact is an excellent handshaking Communication that can interact with nearby devices without any connection or matching.

Further, before playing the audio data, a specified identifier may be further added to a specified position of the audio data, where the specified identifier is used to indicate that the audio data is the audio data corresponding to the group data. After the second terminal acquires the audio data, whether the audio data contains group data may be determined according to whether the designated identifier exists at the designated position of the audio data. The designated position may be a header field of the audio data, or may be other fields.

Specifically, a specific identifier may be added at a specific position of the audio data corresponding to each data in the encoded data, for example, a specific identifier may be added in a header field of the audio data corresponding to each data.

Step 104: the second terminal acquires the audio data.

The second terminal may acquire the audio data from the collected sound. Specifically, the second terminal may collect surrounding sounds through the installed microphone, and when the sounds are collected through the installed microphone, the collected sounds may be first converted into audio data. Furthermore, the collected sound can be recorded first, and then the recorded sound is converted into audio data.

Specifically, the operation of converting the collected sound into the audio data may be: and carrying out digital processing on the collected sound to obtain the audio data. The second terminal may perform PCM decoding on the collected sound to obtain PCM audio data, and then determine the PCM audio data as the audio data.

Step 105: and when the second terminal converts the audio data to obtain group data, the second terminal joins the group according to the group identification and the group entering password included in the group data.

After the audio data is acquired, the second terminal may further convert the audio data to convert the audio data into group data.

Specifically, converting the audio data may include the following steps 1051 and 1055:

step 1051: the audio data is subjected to fast fourier transform to obtain a plurality of sound frequencies.

By performing fast fourier transform on the audio data, a sound frequency corresponding to each of a plurality of pieces of sound included in the audio data can be obtained.

Step 1052: and determining data corresponding to the plurality of sound frequencies according to the corresponding relation between the stored data and the sound frequencies.

Specifically, the operation of determining the data corresponding to the plurality of sound frequencies according to the correspondence between the stored data and the sound frequencies may include the following two implementation manners:

the first implementation mode comprises the following steps: if the stored data and the sound frequency corresponding relationship includes a plurality of first data and corresponding sound frequencies, and the plurality of first data are determined based on all the constituent data of the group identification and the group entering password, the first data corresponding to the specified sound frequency may be determined according to the stored data and the sound frequency corresponding relationship, and the first data is determined as the data corresponding to the specified sound frequency. The specified sound frequency may be any one of the plurality of sound frequencies. The first data may be determined based on all constituent data of the group identification and the group entry password.

The second implementation mode comprises the following steps: if the corresponding relationship between the data and the sound frequency comprises a plurality of first data and corresponding sound frequencies, and a plurality of second data and corresponding sound frequencies, the sound frequencies corresponding to the plurality of second data are greater than the sound frequencies corresponding to the plurality of first data, the plurality of second data and the plurality of first data are in one-to-one correspondence, and the plurality of second data are obtained by respectively converting the plurality of first data, when the initial data corresponding to the specified sound frequency is determined to be the first data according to the corresponding relationship between the stored data and the sound frequency, the first data is determined to be the data corresponding to the specified sound frequency, and the specified sound frequency is any sound frequency in the plurality of sound frequencies; when the initial data corresponding to the specified sound frequency is determined to be the second data according to the corresponding relation between the stored data and the sound frequency, the second data is converted into the first data according to the corresponding relation between the plurality of stored first data and the plurality of stored second data, and the first data is determined to be the data corresponding to the specified sound frequency.

Step 1053: the encoded data is determined based on the data corresponding to the plurality of audio frequencies.

Specifically, data composed of data corresponding to the plurality of audio frequencies may be determined as the encoded data. In the embodiment of the present invention, the encoded data is generally hexadecimal data.

Step 1054: the source code data is obtained by performing a solomon decoding on the encoded data.

The source code data is obtained by the group identification and the group entering password. The group identification is a group ID.

Specifically, the encoded data may be subjected to solomon decoding to obtain decoded data, and then the source code data may be determined by converting the decoded data into decimal data.

Wherein, the coded data obtained by performing the solomon coding on the source code data is hexadecimal data, and the coded data includes both the hexadecimal source code data and the hexadecimal redundant code, so that the determining the source code data by converting the decoded data into decimal data includes: and converting the data except the redundant codes in the decoded data into decimal data, and determining the decimal data as the source code data.

In one embodiment, the data of the first preset number of bits in the decoded data may be determined as data other than the redundancy code, that is, the data of the first preset number of bits in the decoded data may be converted into decimal data, and the decimal data may be determined as the source code data. For example, when the preset number of bits is 8, the first 8-bit data in the decoded data may be converted into decimal data.

For example, when the encoded data is 12CAB7DFEECBA9Then, by performing solomon decoding on the encoded data, 123ABCD can be obtainedFEDCBA9Then removing the redundancy codeData other than FEDCBA9123ABCD is converted into decimal data, which is the source code data.

Step 1055: and determining the group data according to the source code data.

The source code data is composed of a group identifier and an group entering password, so that the group identifier and the group entering password can be determined from the source code data, and the group identifier and the group entering password are the group data.

For example, when the group ID is a group ID, and the group ID is a number and the group-in password is composed of the first M even-numbered digits of the group ID, the last M data of the source code data may be determined as the group-in password, and the remaining data may be determined as the group ID.

In one possible embodiment, the process of converting the audio data may be as shown in fig. 1G, first performing fourier transform on the audio data to obtain a plurality of sound frequencies; then decoding the plurality of sound frequencies to obtain hexadecimal data; and then, performing Solomon decoding on the hexadecimal data to determine to obtain source code data, and obtaining the group data based on the source code data.

Further, before converting the audio data into group data, the method further includes: and when the specified identification is acquired from the specified position of the audio data, the step of converting the audio data into group data is executed. When the specified identification is not acquired from the specified position of the audio data, the audio data is not converted. Therefore, meaningless conversion of the audio data irrelevant to the group data can be avoided, the processing load of converting the audio data is reduced, and the accuracy of data processing is improved.

According to the group identifier and the group entering password, the operation of joining the group indicated by the group identifier may be: acquiring a user identifier of the current login of the second terminal; sending a group sending request to the server, wherein the group sending request carries the user identifier, the group identifier and the group entering password, and the group entering request is used for requesting the server to add the user identifier to the group according to the group identifier and the group entering password.

Through the steps, the second terminal can automatically join the group based on the acquired audio data, namely, the group members can rapidly join the group without performing extra task operation, and the group joining efficiency is improved.

Further, in order to protect the privacy of the user, the user can also join the group according to the group identifier and the group entering password when the group entering operation for the group data is detected. Wherein the confirmation of the group entry operation may be triggered by the group member based on a confirmation window displayed by the second terminal.

For example, after the second terminal determines that the group data is obtained, a confirmation window for inquiring whether to join the group may be displayed based on the group data. When the confirmation group entering operation is detected based on the confirmation window, the group identification and the group entering password can be added into the group; when no confirmed group entry operation is detected based on the confirmation window, then the group is not added.

In an embodiment, by using the clustering method provided in the embodiment of the present invention, a group can implement one-key clustering, and the clustering process can be as shown in fig. 1H. 1. The group owner clicks a 'quick group pulling' button displayed by the first terminal; 2. the first terminal generates group data and uploads the group data to the server; 3. the first terminal converts the group data into audio data and plays the audio data; 4. a second terminal near the first terminal hears the sound and decodes the heared sound into group data. 5. And the second terminal joins the group according to the group data.

The embodiment of the invention creates a brand-new group pulling mode on the basis of sound wave communication, realizes the function of quickly establishing a group and simultaneously pulling the members of the nearby group into the group, well optimizes the establishment flow and establishment experience in a development scene, and can establish the group simply and quickly by one step through the method.

Further, when a microphone or a processor of the second terminal fails to acquire audio data or cannot convert the acquired audio data into group data, the second terminal may join the group according to the group data input by the group members. The group data input by the group member can be informed by the group owner, and the group owner can acquire the group data based on the group data displayed by the first terminal. By setting group data including the group entering password, the group entering mode is enriched.

In the embodiment of the invention, the first terminal can establish the group and acquire the group data comprising the group identifier and the group entering password according to the group establishing operation of the group owner, then the group data is sent to the second terminals of the group members through the audio data, and the second terminals can directly join the group according to the group data received through the audio data. That is, the group owner can invite the group members to join the group at the same time through the audio data played by the first terminal, and each group member can join the group at the same time according to the audio data received by the second terminal, thereby avoiding the tedious operation that the group owner needs to invite the group members one by one, or the group members need to join the group one by one, saving the group building time and improving the group building efficiency.
