Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.

Example one

Fig. 1 is a flowchart of a friend adding method according to an embodiment of the present application. The method and the device for adding the friends can be suitable for the situation that the friends are added to the target account without scanning the two-dimensional code or manually inputting the target account when the friends are added in the near field. The method can be executed by a friend adding device, which can be implemented by software and/or hardware and is specifically configured in an electronic device, and the electronic device can be a mobile terminal or a fixed terminal. Referring to fig. 1, a method for adding a friend provided in an embodiment of the present application includes:

and S110, determining at least one target terminal having close contact relation with the current terminal according to the Bluetooth association information of the current terminal.

The terminal is a terminal with a bluetooth function. The terminal may be a mobile terminal and/or a fixed terminal. Specific types of terminals typically include, but are not limited to, bluetooth enabled smartwatches, cell phones, computers, and the like. The terminal with the bluetooth function may be a terminal supporting a classic bluetooth function, and may also be a terminal supporting a low-power-consumption bluetooth function, which is not limited in this embodiment of the present application.

It should be noted that, when the friend adding method of the present application is implemented, at least the same type of social software is installed in each terminal for friend adding, and each terminal needs to be in a state of turning on bluetooth. Generally, after any terminal with a bluetooth function starts bluetooth, a bluetooth broadcast data packet is sent to the surroundings, and because the bluetooth broadcast data packet contains terminal-related information, when other surrounding terminals start bluetooth to perform inquiry scanning, the existence of the terminal can be found.

The current terminal is a terminal with a friend adding requirement.

When using bluetooth functionality for wireless connectivity, a master role and a slave role are typically assigned. When the current terminal is used as a main role and any other terminal around the current terminal is used as a slave role, when the current terminal starts the bluetooth for inquiry and scanning, the current terminal receives broadcast data packets sent by other terminals around the current terminal, and then obtains an RSSI (Received Signal Strength Indication) value, namely the bluetooth Signal Strength, corresponding to the Received broadcast data packets at a system interface of the current terminal. A terminal with Bluetooth function, which can switch between the two roles and work in a role mode at ordinary times to wait for other terminals to connect; when data transmission is required, the mode is switched to a main role mode so as to initiate a call to other terminals.

The bluetooth associated information of the current terminal is data information required for calculating the contact distance between the master device and the slave device by taking the current terminal as the master device and other terminals around the current terminal as slave roles. The contact distance between the current terminal and other terminals is related to factors such as Bluetooth signal strength, signal propagation index and environmental attenuation factor.

The close contact relation refers to a contact relation under the condition that the contact distance between the current terminal and other terminals around the current terminal is smaller than a preset contact threshold value. The preset contact threshold value can be preset according to the actual friend adding requirement. It can be understood that, in the case that the current terminal and the target terminal have a close contact relationship, the actual distances between the current terminal and the target terminal are relatively close.

The target terminal is a terminal which is determined to have close contact relation with the current terminal according to the contact distance between the current terminal and other terminals in other terminals around the current terminal, and the terminal is also called as the target terminal. It can be understood that when the current terminal starts bluetooth for inquiry scanning, there may be a plurality of target terminals meeting the close contact relationship with the current terminal at the same time.

Alternatively, the contact distance between the current terminal and the other terminals may be calculated by the following ranging formula:

wherein d represents the contact distance between the current terminal and other terminals, RSSI represents the Bluetooth signal strength of other surrounding terminals received by the current terminal, a represents the signal strength when the current terminal is separated from other terminals by one meter, and n represents an environment attenuation factor. Since the positions of other terminals around the terminal cannot be accurately known, where a and n are constants, the positions can be set according to empirical values.

Considering that the calculation result of the contact distance is very unstable depending on the bluetooth signal intensity, and is easily interfered by various factors such as the environment and the terminal itself. It is understood that the determination of whether the current terminal has a close contact relationship with other terminals based on the calculation result of the unstable contact distance will also be inaccurate.

Optionally, by using a deep learning method, a basic data set is constructed from at least one of related variables such as bluetooth signal intensity, terminal model type information, terminal activation state information, terminal movement state information, terminal audio frequency state information, and the like, and a pre-constructed deep learning model is trained according to the constructed basic data set to obtain a close contact monitoring model for judging close contact relationships, so that the accuracy and stability of judging the close contact relationships are improved. Wherein, the deep learning model can be constructed based on the neural network model.

It can be understood that, in the case that the current terminal and the target terminal have a close contact relationship, the current terminal and the target terminal can perform wireless communication via bluetooth within a short distance, so as to perform secure and efficient transmission of data, such as transmission of data of documents, voice, video, and the like.

S120, sending self account information to a target account of at least one target terminal, and receiving a friend adding request fed back by the target account based on the account information of the current terminal.

The target account refers to a target account of a certain set type for adding friends. Target accounts include, but are not limited to, social accounts of the friends, entertainment, and news categories, and the like.

Optionally, a manual confirmation mode is adopted, and a target account of a target terminal for friend addition is selected from an operation interface of the current terminal.

Or optionally, acquiring a voice instruction of the current terminal, wherein the voice instruction is sent by a user or an authorized user of the current terminal; based on a voice instruction of the current terminal, segmenting text information in the voice instruction by adopting a natural language processing mode; matching the target terminal identification and/or the target account type to be added by the friend of the current terminal based on the segmentation result; and matching the target account of the target terminal to be added by the friend of the current terminal according to the target terminal identification and/or the target account type.

Further, establishing Bluetooth communication connection based on the close contact relationship between the current terminal and the target terminal, and sending self account information to the target account of at least one target terminal by the current terminal; and after the target account of the target terminal receives the account information of the current terminal, sending a friend adding application to the account of the current terminal. In the process of sending the friend addition application, the related friend addition setting information may be set by default or according to the prompt information in the voice instruction of the current terminal, which is not specifically limited in the embodiment of the present application.

It is noted that the current terminal may simultaneously receive friend adding requests sent by a plurality of target terminals, because the current terminal sends its own account information to the plurality of target terminals simultaneously based on a bluetooth communication mode, and after the target account of the target terminal receives the account information sent by the current terminal, the relevant operation of adding friends is automatically completed in its own social account.

It can be understood that, under the condition that the current terminal and the target terminal have close contact relationship, after the self account information is sent to the target account of at least one target terminal, the target terminal can search the account information of the current terminal according to the self account information of the current terminal and send a friend adding application to the account of the current terminal; the current terminal receives a friend adding request fed back by a target account based on account information of the current terminal, and the current terminal can acquire request information for adding the target account of the target terminal through the friend adding request sent by the target account of the target terminal, so that the purpose of adding friends to the target account of the target terminal is achieved.

S130, responding to the received friend adding request, and executing friend adding operation.

Optionally, a manual adding mode is adopted, and the execution operation of friend adding on the target account of the target terminal is completed in the operation interface of the current terminal.

Or optionally, based on the friend adding method of the present application, after the authorization of the corresponding target account is obtained, the operation of adding the friend can be automatically performed according to the relative default information added by the friend. The default information may be that a nickname of a friend is set as a "target account" by default, a friend group is set as a "friend" by default, a friend adding mode is set to be added by a bluetooth method, and the like.

It can be understood that the current terminal will respond to the friend addition request sent by the target terminal, and confirm the friend addition request sent by the target terminal through the operation interface of the current terminal to agree with the friend addition request sent by the target terminal, so as to complete the friend addition operation.

According to the method and the device, after at least one target terminal which is in close contact with the current terminal is determined according to the Bluetooth related information of the current terminal, self account information is sent to the target account of the at least one target terminal, a friend adding request fed back by the target account based on the account information of the current terminal is received, meanwhile, a friend adding operation is executed in response to the received friend adding request, the purpose that under the condition that a two-dimensional code is not scanned or the target account is manually input, high-efficiency wireless data transmission is carried out based on the close contact relationship of the current terminal and the target terminal, the self account information of the current terminal is successfully sent to the target account of the target terminal, and the personal account is invisible in the friend adding process is achieved; meanwhile, the current terminal can send the account information of the current terminal to the target accounts of the plurality of target terminals, the purpose of adding a plurality of friends at the same time is achieved, and the safety and convenience of friend adding are improved.

Example two

Fig. 2 is a flowchart of a friend adding method according to a second embodiment of the present application, which is an extension of the foregoing scheme based on the foregoing embodiment.

Further, the operation of determining at least one target terminal having close contact relation with the current terminal according to the Bluetooth related information of the current terminal is refined into the operation of inputting the Bluetooth related information of the current terminal into a trained close contact monitoring model and determining the close contact result of the current terminal and each candidate terminal; and selecting at least one candidate terminal as the target terminal according to the close contact result so as to perfect a determination mechanism for judging the close contact relation.

Wherein explanations of the same or corresponding terms as those of the above-described embodiments are omitted.

Referring to fig. 2, a method for adding a friend provided in this embodiment includes:

s210, inputting the Bluetooth related information of the current terminal into the trained joint sealing monitoring model, and determining the close contact result of the current terminal and each candidate terminal.

The candidate terminal refers to other terminals which start the bluetooth function around the current terminal.

Optionally, the bluetooth association information includes bluetooth signal strength and terminal additional information.

The bluetooth signal strength is an RSSI value corresponding to a broadcast data packet received from another terminal when the current terminal starts bluetooth to perform inquiry scan on other terminals starting bluetooth around for the current terminal.

The terminal additional information is additional information that has an influence on determining whether or not the current terminal and each candidate terminal have a close contact relationship with respect to the current terminal and/or the candidate terminals.

Optionally, the terminal additional information includes at least one of terminal activation state information, terminal movement state information, terminal model type information, terminal audio state information, and the like.

The terminal activation state information indicates whether the terminal is shielded or not. For example, when the terminals are placed in a bag or a pocket, there is a high probability that the terminals are shielded by obstacles such as clothes, bags, human bodies and the like, and the terminal screen is in an inactive state; when the terminal is operated, the probability that the terminals are shielded is small, and the terminal is in an activated state.

The terminal model type information refers to the type information of the terminal, and the radar transmitting power of the terminal is different according to different types of the terminal. For example, the radar transmission power of the mobile phone of the apple operating system is significantly higher than that of the mobile phone of the android operating system, and the radar transmission power is closely related to the bluetooth signal strength.

The terminal movement state information refers to a movement state of the terminal itself, such as whether the terminal is stationary or moving or not, whether the terminal is moving at a certain acceleration or not, and the like. The terminal audio state information refers to an audio decibel value of the terminal. According to actual research and experiments, the terminal mobile state information and the terminal audio state information have certain influence on judgment of close contact relation in different scenes.

It can be understood that, the close contact relation is judged by simply depending on the strength of the bluetooth signal, the judgment result is very unstable, and the judgment result is easily interfered by various factors such as the environment and the terminal. In different use states, the terminal has different additional information, such as terminal activation state information, terminal movement state information, terminal audio state information, and the like, which have a great influence on the close contact relationship determination. Therefore, taking into consideration the above-described factors relating to the determination of the intimate contact relationship, the accuracy of the result of determination of the intimate contact relationship will be further effectively improved.

The contact monitoring model is a trained model capable of judging the close contact relationship between the current terminal and each candidate terminal.

Illustratively, in the training phase of the contact monitoring model, the following method can be adopted: 1) data collection: and acquiring a plurality of groups of data sets which influence the close contact relationship under different scenes, wherein the data sets comprise Bluetooth signal strength, terminal activation state information, terminal movement state information, terminal audio state information and the like. 2) Data set partitioning: the data set is divided into two types, namely close contact and non-close contact, by adopting a manual calibration method. 3) Network construction: and determining input, output, hidden layer and related parameters of the network, and establishing a joint sealing monitoring model based on the deep neural network. 4) Model training: and training the joint sealing monitoring model for multiple times based on a supervised learning method until obtaining a joint sealing monitoring model which can judge the close contact relation more stably and accurately.

Optionally, before training the contact monitoring model, correlation analysis is performed on variables such as bluetooth signal strength, terminal activation state information, terminal movement state information, terminal model class information, and terminal audio state information based on a correlation analysis method such as correlation coefficient, information gain, chi-square test, and the like, so as to determine a variable having a higher correlation with the close contact relationship. It can be understood that, by performing correlation analysis on the variables, the trained joint monitoring model can ensure higher accuracy in determining the close contact relationship.

Optionally, when the bluetooth is started, each terminal can upload the state information of the terminal itself to the background management server in real time; the background management server stores a pre-trained joint sealing monitoring model, when the current terminal starts Bluetooth scanning, the background management server can judge the close contact relation of other terminals around the current terminal, and transmits the close contact result to the current terminal. It is understood that various sensors are installed in each terminal for monitoring the state of the terminal itself, for example, an acceleration sensor, an optical fiber sensor, and the like are installed in the terminal.

It can be understood that the contact monitoring model established based on the machine learning method can comprehensively take various factors related to the contact relationship into consideration, has strong parallel distribution processing capability and learning capability, and can stably and accurately judge the contact relationship.

And S220, selecting at least one candidate terminal as a target terminal according to the close contact result.

The results of intimate contact include intimate contact and non-intimate contact, among others. Under the condition of close contact, the actual distance between the user of the current terminal and the user of the target terminal is relatively close, and the Bluetooth communication connection and the near field communication are suitable to be carried out.

Optionally, according to the close contact result, in the target terminal having a close contact relationship with the current terminal, selecting a target account of the target terminal for adding the friend in an operation interface of the current terminal by adopting a manual confirmation mode.

Or optionally, acquiring a voice instruction of the current terminal, wherein the voice instruction is sent by a user or an authorized user of the current terminal; based on a voice instruction of a current terminal, segmenting text information in the voice instruction by adopting a natural language processing mode; matching the target terminal identification and/or the target account type to be added by the friend of the current terminal based on the segmentation result; and matching the target account of the target terminal to be added by the friend of at least one current terminal in the target terminals with close contact relation with the current terminal according to the target terminal identification and/or the target account type.

S230, sending self account information to a target account of at least one target terminal, and receiving a friend adding request fed back by the target account based on the account information of the current terminal.

And S240, responding to the received friend adding request, and executing friend adding operation.

On the basis of the embodiment, the close contact monitoring model is adopted, the close contact judging mode is further optimized, and the effect that the current terminal can safely and quickly add friends to the target account of the target terminal is guaranteed.

EXAMPLE III

Fig. 3 is a flowchart of a friend adding method provided in the third embodiment of the present application, which is an extension of the above-described solutions in the third embodiment of the present application.

Further, after the operation of determining at least one target terminal in close contact with the current terminal according to the Bluetooth related information of the current terminal and before the operation of sending self account information to a target account of the at least one target terminal, the operation is added, and whether an initiating user of the voice instruction is an authorized user of the current terminal is determined according to the voice instruction of the current terminal; and if the initiating user is the authority user of the current terminal, triggering and executing the operation of sending the self account information to the target account so as to perfect the authority determining mechanism of the current terminal.

Further, the operation of sending self account information to a target account of at least one target terminal is detailed into the operation of determining a terminal identifier of at least one target terminal according to the voice instruction of the current terminal; and sending self account information to at least one target account of the target terminal according to the terminal identification so as to perfect a determination mechanism of the target account of the target terminal.

Further, before operation "receiving a friend adding request fed back by the target account based on the account information of the current terminal", adding operation "determining a target friend group according to a voice instruction of the current terminal; and responding to the received friend adding request, executing friend adding operation, and moving the added friend to the target friend group' to perfect the determination mechanism of the target friend group.

Wherein explanations of the same or corresponding terms as those of the above embodiments are omitted.

Referring to fig. 3, the method for adding a friend provided in this embodiment includes:

and S310, inputting the Bluetooth related information of the current terminal into the trained joint sealing monitoring model, and determining the close contact result between the current terminal and each candidate terminal.

And S320, selecting at least one candidate terminal as a target terminal according to the close contact result.

In this embodiment, according to the result of the close contact, a candidate terminal having a close contact relationship with the current terminal is selected. Further, a target terminal for friend addition can be selected from the candidate terminals.

S330, determining whether the user initiating the voice instruction is the authority user of the current terminal according to the voice instruction of the current terminal.

Wherein, the voice instruction is sent by the user of the current terminal.

Preferably, the voice instruction of the current terminal is input into a pre-trained voiceprint recognition model, and whether the voice initiating user is the authority user of the current terminal is determined.

The voiceprint recognition model is capable of recognizing voiceprint features in a voice command to determine whether a user initiating the current voice command is an authority user of the current terminal, namely whether a friend adding action to be performed by the current terminal is initiated by the authority user of the current terminal. It is easy to understand that the voice command of the current terminal is not necessarily the authority user of the current terminal, and the safety of the friend adding process is further ensured by confirming the authority user of the current terminal.

Illustratively, as shown in FIG. 4, the overall process of voiceprint recognition of a voice instruction using a voiceprint recognition model is illustrated. First, before a voice command is recognized using a voiceprint recognition model, the voiceprint recognition model needs to be constructed. The establishment of the voiceprint recognition model consists of preprocessing, feature extraction, training and the like. Preprocessing refers to performing pre-emphasis processing, framing processing, and windowing processing on speech in the speech data set. Feature extraction refers to extracting voiceprint features of speech, such as features of linear prediction cepstrum Coefficients, Mel-Frequency spectral Coefficients, Mel-Frequency cepstral Coefficients (MFCCs), and the like. The training is to train the constructed voiceprint recognition model based on a machine learning method to obtain a voiceprint recognition model capable of carrying out identity recognition on user voice. The voiceprint recognition model can be a convolutional neural network model or a gaussian mixture model. The voiceprint recognition process can be vividly understood as a process of unlocking by using a password, namely a process of obtaining a password combination through preprocessing and feature extraction, obtaining a password model library through training, and a process of converting a voice command of a current terminal user into a password and checking the password with the password model library through recognition.

It can be understood that voiceprint recognition is a technology of biometric authentication, and can safely and accurately confirm whether the initiating user of the voice command is the authorized user of the current terminal, because the voice is similar to pupil, fingerprint and face recognition and is composed of unique biological features. According to the voice command of the current terminal, whether the initiating user of the voice command of the current terminal is the authority user of the current terminal can be confirmed, and the relevant operations such as friend adding and the like can be safely and conveniently executed without manually inputting an account password in the friend adding process.

Alternatively, more than one authorized user of the current terminal may be used, as long as the authorized user at the current terminal can be used as the authorized user of the current terminal. The authorization means that the voice information of the voice instruction initiator is stored in the current terminal.

And S340, if the initiating user is the authority user of the current terminal, triggering and executing the operation of sending the self account information to the target account.

The authorized user refers to a user who can authorize friend adding operation of the current terminal. It can be understood that the operation of adding a friend to a target account of another terminal can be implemented as long as the user is authorized in the current terminal.

It can be understood that, when the initiating user of the voice instruction is an authorized user bound to the current terminal, that is, the voiceprint feature of the initiating user is consistent with the voiceprint feature pre-stored in the current terminal, the initiating user of the voice instruction is considered to share the authority of sending the self-account information to the target account of the target terminal, so that the operation of sending the self-account information to the target account of the target terminal is triggered and executed, the situation that an unauthorized user steals terminal equipment for data transmission due to other people is avoided, and the purpose of protecting the account information of the user to which the terminal belongs is achieved.

And S350, determining the terminal identification of at least one target terminal according to the voice command of the current terminal.

The terminal identifier is a terminal identifier specially used for Bluetooth matching.

Alternatively, the terminal identification may be the user name of the target terminal account. Or alternatively, the terminal identifier may be uniquely assigned by the user when registering the specific software, and the terminal identifier is formed by combining numbers and/or letters. The specific software refers to application software developed in connection with executing the friend adding method of the present application. It can be understood that, a user using the current terminal may obtain the terminal identification information of the friend to be added in advance in a near field communication manner.

Optionally, the voice instruction includes a target terminal identifier; and/or the voice instruction comprises a target terminal identification and a target account type; and/or the voice command comprises a target terminal identification, a target account type and additional remark information. The target account type is used for making explicit the social accounts added by the friends. The additional remark information is used for name-card introduction of names, social relations and the like of users to which the current terminal belongs. The social relationship refers to a relationship with a friend adder, such as a relationship of a colleague, a classmate, a client and the like.

The format of the voice command can be preset. For example, the format of the voice instruction is "add a terminal of [ target terminal identifier ] as a friend" and "add a terminal of [ target terminal identifier ] as a friend" (target account type), etc., and at the same time, additional remark information related to friend addition, such as a friend nickname (i.e., remark), a friend group, a friend addition reason, etc., may also be added at the end of the voice instruction. It can be understood that, by presetting the format of the voice command, the effect of accurately identifying the voice command can be achieved, thereby further ensuring the selection of the target terminal.

Optionally, if the target account type and the additional remark information are not obtained from the voice instruction, the information may be set by default. If the target account type is specified, the target account type to which the account information sent by the user to which the current terminal belongs is referred, and the remark information can be that the nickname of the friend is set as the target account number by default, the friend group is set as friend by default, the friend adding reason is set as friend by default, and the like. It is easy to understand that both parties who add friends can modify friend business cards according to personal wishes after adding the other party as friends under the default information.

Optionally, based on the voice instruction of the current terminal, segmenting text information in the voice instruction by adopting a natural language processing mode; matching the target terminal identification and/or the target account type to be added by the friend of the current terminal based on the segmentation result; and matching the target account of the target terminal to be added by the friend of at least one current terminal in the target terminals with close contact relation with the current terminal according to the target terminal identification and/or the target account type.

And S360, sending self account information to the target account of at least one target terminal according to the terminal identification.

It can be understood that, after the terminal identifier of the target terminal is identified according to the voice instruction of the current terminal, the target terminal consistent with the terminal identifier may be matched in the target terminals having close contact with the current terminal, and after the user of the current terminal shares the authority to send the self account information to the target account of the target terminal, the operation of sending the self account information to at least one target terminal is executed.

And S370, determining the target friend group according to the voice command of the current terminal.

The target friend group refers to a friend group which is moved to a designated friend group in the process of adding friends, for example, the target friend group may be a friend group, a classmate group, a colleague group, or the like. The target friend grouping information can be obtained from the additional remark information of the voice instruction.

Optionally, both the current terminal and the target terminal may move the added friend to the designated target friend group according to the friend group information.

It can be understood that, in the process of adding friends, the target friend group information identified by the voice instruction of the current terminal can make the default group information referred to when the current terminal and the user of the target terminal add friends, so that the friend group does not need to be manually performed, and the target friend group information provides a basis for the whole automatic friend adding process.

And S380, receiving a friend adding request fed back by the target account based on the account information of the current terminal.

And S390, responding to the received friend adding request, executing friend adding operation, and moving the added friend to a target friend group.

It can be understood that, in the process of adding friends, friends that are successfully added currently can be automatically moved to corresponding target friend groups according to the target friend group information. Optionally, the user can adjust the group to which the friend belongs at any time according to personal wishes.
