Portable WIFI devices are usually suitable for users who travel, work in the field or live in areas with poor network coverage.

[0073] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0074] The embodiment of the present application provides a signal adjustment method based on portable WIFI. The execution subject of the signal adjustment method based on portable WIFI includes but is not limited to at least one of the electronic devices such as a server and a terminal that can be configured to execute the method provided by the embodiment of the present application.

The server includes but is not limited to: a single server, a server cluster, a cloud server or a cloud server cluster, etc.

[0075] Reference Figure 1 FIG. 1 is a flow chart of a signal adjustment method based on a portable WIFI according to an embodiment of the present invention. In this embodiment, the signal adjustment method based on the portable WIFI includes:

[0076] S1. Receive a WIFI adjustment instruction, and confirm a signal adjustment environment according to the WIFI adjustment instruction, wherein the signal adjustment environment includes: a power source, n WIFI user devices, a WIFI carrier device, and a portable WIFI, wherein 2≤n≤m, and n is an integer, and m is a preset connection threshold. The portable WIFI will send different network signals according to different WIFI user devices.

[0077] It should be explained that the WIFI adjustment command is generally initiated by the carrier of the portable WIFI through the corresponding APP, and different portable WIFIs generally correspond to different APPs. For example, Xiao Zhang is the carrier of Huawei portable WIFI. Now there are multiple devices near Xiao Zhang that need to connect to the Huawei portable WIFI. In order to adjust the signal emitted by it in a multi-device usage environment, Xiao Zhang initiates the WIFI adjustment command through the Huawei Smart Home APP on his mobile phone.

[0078] In the embodiment of the present invention, the environment for adjusting the WIFI signal is a signal adjustment environment, and the signal adjustment environment includes a power source, n WIFI user devices, a WIFI carrier device, and a portable WIFI.

[0079] The key point is that the main function of the power supply is to provide power for the portable WIFI. The WIFI carrier device refers to a device that can control the portable WIFI and is operated by the carrier of the portable WIFI. Optionally, an iPad can be used as a WIFI carrier device. The WIFI user device refers to a device connected to the portable WIFI and is operated by the user of the portable WIFI. Optionally, an iPhone can be used as a WIFI user device. The preset connection threshold m refers to the maximum number of devices that the portable WIFI can connect to, and the connection thresholds of different portable WIFIs are different. For example, the connection threshold of Huawei's portable WIFI is 16.

[0080] It should be explained that the portable WIFI can send different network signals according to different WIFI user devices. For example, on the Huawei Smart Home APP, by setting the parameters of the Huawei portable WIFI, you can set different bandwidths for different devices, and you can set the signal frequency band and channel value in the WLAN advanced settings.

[0081] Further, the receiving of the WIFI adjustment instruction and determining the signal adjustment environment according to the WIFI adjustment instruction includes:

[0082] After receiving the WIFI adjustment instruction, starting the power supply;

[0083] When the startup is successful, the n WIFI user devices and WIFI carrier devices are self-tested;

[0084] When the self-test is passed, the parameters of the portable WIFI are set respectively until the parameter setting is successful, and a signal adjustment environment including a power source, n WIFI user devices, a WIFI carrier device and the portable WIFI is obtained.

[0085] It needs to be explained that the parameters for setting portable WIFI include network speed and the duration of sending network signals.

[0086] For example, after the self-test is passed, the network speed of the portable WIFI can be set to 20M / S, and the duration of sending the network signal can be set to 30 minutes.

[0087] S2. Receive the signal connection instruction initiated by the extracted WIFI user device, send the signal connection instruction to the WIFI carrier device, and when the WIFI carrier device successfully receives the signal connection instruction, obtain the device information of the WIFI user device, wherein the device information includes: MAC address and two-dimensional location coordinates.

[0088] It should be explained that the signal connection command is sent by the WIFI user device, and its main purpose is to request to connect to the portable WIFI. The MAC address is composed of 48-bit binary numbers. Each device in the network has a unique network identifier, which is the MAC address. The two-dimensional location coordinates refer to the location coordinates of the device on the electronic map.

[0089] For example, if Xiao Zhang's computer successfully receives the signal connection command initiated by Xiao Zhao's mobile phone, in order to set the most suitable portable WIFI parameters for the mobile phone, it is necessary to obtain the device information of the mobile phone, obtain the MAC address by querying the system details page of the mobile phone, obtain the longitude and latitude through the positioning system of the mobile phone and Gaode Map, and then use the coordinate system conversion system of Gaode Open Platform to obtain the two-dimensional location coordinates.

[0090] It should be understood that using the coordinate system conversion system of the AutoNavi open platform to convert longitude and latitude into two-dimensional position coordinates is a prior art and will not be described in detail here.

[0091] S3. Calculate the simulated signal distance using the two-dimensional position coordinates and the pre-acquired portable WIFI position coordinates, and use the simulated signal distance to set the signal transmission frequency band of the portable WIFI to obtain the target portable WIFI.

[0092] Exemplarily, the location coordinates of the portable WIFI are also obtained by the coordinate system conversion system of the AutoNavi open platform. In order to obtain the location coordinates of the portable WIFI, Xiao Zhang places the device he carries and the portable WIFI in the same position, and then obtains its location coordinates through the positioning system of the device and the AutoNavi map. The location coordinates are the location coordinates of the portable WIFI.

[0093] In detail, the two-dimensional position coordinates and the pre-acquired portable WIFI position coordinates are used to calculate the simulated signal distance, and the calculation formula is as follows:

[0094]

[0095] Among them, |X l | is the simulated signal distance, x1 and y1 are the x-axis coordinate and y-axis coordinate in the two-dimensional position coordinate, x0 and y0 are the x-axis coordinate and y-axis coordinate in the portable WIFI position coordinate, k is the preset weight coefficient, H is the preset coefficient and is related to the humidity in the environment.

[0096] Importantly, the preset weight coefficient k is determined by the number of obstacles in the environment and the material of the obstacles.

[0097] It should be understood that humidity reflects the water vapor content in the air. These water molecules in the air have a certain ability to block and absorb network signals, thus affecting the propagation of network signals.

[0098] It should be explained that the simulated signal distance is an approximate simulation of the distance that the network signal can be transmitted under ideal conditions. Because the preset distance threshold is under ideal conditions, the actual propagation distance is converted into a simulated signal distance through different real-world conditions, such as obstacles and other parameters, and then compared with the distance threshold, which will make the comparison result more in line with different real-world conditions. Among them, the actual propagation distance refers to the distance that the network signal propagates in the real environment, which is calculated by the two-dimensional position coordinates and the portable WIFI position coordinates, and the calculation formula of the simulated signal distance includes this calculation process.

[0099] For example, if the propagation distance of the network signal emitted by the portable WIFI under ideal conditions, that is, the simulated signal distance is 20m, but considering factors such as obstacles in the propagation process, its actual propagation distance is only 15m.

[0100] Furthermore, the method of using the simulated signal distance to set the signal transmission frequency band of the portable WIFI to obtain the target portable WIFI includes:

[0101] comparing the simulated signal distance with a preset distance threshold;

[0102] If the simulated signal distance is greater than or equal to the preset distance threshold, the signal transmission frequency band of the portable WIFI is set to the 2.4 GHZ frequency band, and the target portable WIFI is obtained;

[0103] If the simulated signal distance is less than the preset distance threshold, the signal transmission frequency band of the portable WIFI is set to the 5 GHZ frequency band to obtain the target portable WIFI.

[0104] It should be explained that the preset distance threshold is determined by the model of the portable WIFI. Each portable WIFI has a certain distance threshold, which represents the maximum propagation distance of the 5GHZ band signal under ideal conditions. The signal transmission frequency band refers to the radio frequency range used by the portable WIFI to send wireless signals. At present, there are two commonly used WIFI frequency bands: 2.4GHz and 5GHz. The 2.4GHz frequency band has a long transmission distance, but a slow transmission rate; the 5GHz frequency band has a short transmission distance, but a fast transmission rate. The target portable WIFI refers to the portable WIFI after the signal transmission frequency band is set.

[0105] For example, by modifying the WLAN advanced settings option in the Huawei Smart Home APP, you can set the signal transmission frequency band of Huawei Mobile WIFI.

[0106] S4. Obtain historical connection records of the WIFI user equipment, and generate a signal constraint model of the WIFI user equipment according to the historical connection records.

[0107] It should be explained that the historical connection record of the WIFI user device refers to the historical record of the WIFI user connecting to the portable WIFI, including data such as connection duration, connection rate and signal fluctuation. The signal constraint model refers to a model containing four sets of constraint functions, which constrain different signal conditions through the four sets of constraint functions to obtain different results.

[0108] In detail, the acquiring of the historical connection records of the WIFI user equipment and the generating of the signal constraint model of the WIFI user equipment according to the historical connection records include:

[0109] Query the record of WIFI user equipment using the portable WIFI;

[0110] When it is found that the WIFI user device has a record of using the portable WIFI, all records of using the portable WIFI are extracted to obtain a historical connection record;

[0111] Performing data structuring operation on the historical connection records to obtain structured connection data, wherein the structured connection data includes total connection duration, average connection rate, balanced signal duration, balanced signal rate, peak signal duration, peak signal rate, fluctuation signal duration and fluctuation signal rate, and the sum of the balanced signal duration, the peak signal duration and the fluctuation signal duration is equal to the total connection duration;

[0112] A signal constraint model of a WIFI user device is generated based on the structural connection data.

[0113] It should be explained that data structuring operation is a method of organizing data, that is, extracting the data required for structural connection data from each historical connection record, summarizing and organizing the data and expressing it in the form of a matrix to obtain structural connection data. The total connection time and the average connection rate refer to the total time of connecting to the portable WIFI and the average network speed during this period; the balanced signal time and the balanced signal rate refer to the time when the signal is kept stable when connected to the portable WIFI and the network speed value in the time period corresponding to the balanced signal time; the peak signal time and the peak signal rate refer to the time when the network speed reaches the highest value when connected to the portable WIFI and the network speed value in the time period corresponding to this peak signal time; the fluctuating signal time and the fluctuating signal rate refer to the time when the portable WIFI signal is in a fluctuating state when connected to the portable WIFI and the average network speed when the portable WIFI signal is in a fluctuating state.

[0114] It is understandable that the structural connection data of the WIFI user device can reflect the usage of the portable WIFI, and to a certain extent, the fluctuation of the portable WIFI signal when the WIFI user device is using the portable WIFI can be fed back through the structural connection data. Therefore, by constructing a signal constraint model of the WIFI user device through the structural connection data, the signal generated by the portable WIFI can be made more stable when the WIFI user device is connected to and uses the portable WIFI.

[0115] In detail, the generating of the signal constraint model of the WIFI user equipment based on the structure connection data includes:

[0116] The representation method of structural connection data is as follows:

[0117]

[0118] Among them, D W Indicates the structure connection data corresponding to the WIFI user device, t w ,t p ,t max and t b are the total connection duration, balance signal duration, peak signal duration and fluctuation signal duration, respectively, v W 、v p 、v max 、v b They are the average connection rate, balanced signal rate, peak signal rate and fluctuating signal rate;

[0119] According to the peak signal duration and peak signal rate in the structure connection data, the connection peak coefficient of the WIFI user equipment is calculated. The calculation formula is as follows:

[0120]

[0121] Wherein, M represents the connection peak coefficient, and t0 is the preset balance reference time;

[0122] The structure connection data is used as the input data of the pre-built signal connection classification model to calculate the signal connection type of the WIFI user equipment, wherein the signal connection types include: high fluctuation type, low fluctuation type, low stability type and high stability type;

[0123] The signal constraint model is constructed based on the signal connection type and the connection peak coefficient, wherein the signal constraint model includes four groups of constraint functions, wherein the four groups of constraint functions include: constraint function 1, constraint function 2, constraint function 3 and constraint function 4, and the four groups of constraint functions are as follows:

[0124] Constraint function 1: If the signal connection type is high fluctuation type and the connection peak coefficient is less than the preset first signal threshold, the target portable WIFI stops sending network signals to the WIFI user device;

[0125] Constraint function 2: if the signal connection type is low fluctuation type, and the connection peak coefficient is greater than or equal to the first signal threshold, and the connection peak coefficient is less than the preset second signal threshold, the target portable WIFI sets the channel for sending network signals to the WIFI user equipment to the first channel;

[0126] Constraint function 3: if the signal connection type is low stability, and the connection peak coefficient is greater than or equal to the second signal threshold, and the connection peak coefficient is less than the preset third signal threshold, the target portable WIFI sets the channel for sending network signals to the WIFI user equipment to the second channel;

[0127] Constraint function 4: If the signal connection type is a high stability type, and the connection peak coefficient is greater than or equal to the third signal threshold, the target portable WIFI sets the channel for sending network signals to the WIFI user equipment to the third channel.

[0128] It should be explained that the size of the connection peak coefficient can reflect the relative proportion of the peak signal in all signals when the WIFI user device uses the portable WIFI. The peak signal refers to the signal when the WIFI user device reaches the peak speed after connecting to the portable WIFI. The preset balance reference time t0 is determined by the model of the portable WIFI. Generally, the higher the quality of the portable WIFI, the higher the balance reference time t0.

[0129] Importantly, in order to further quantify the signal stability of the WIFI user equipment, the embodiment of the present invention uses the structural connection data as the input data of the pre-built signal connection classification model to calculate the signal connection type of the WIFI user equipment. It should be emphasized that the signal connection classification model is constructed based on a supervised algorithm, wherein the supervised algorithm includes but is not limited to support vector machines, deep learning and other models, and before using the signal connection classification model, it is necessary to train the signal connection classification model according to the training set until the signal connection classification model meets the training result adjustment, and then it can be used to perform the signal connection classification of the WIFI user equipment.

[0130] In the embodiment of the present invention, the signal connection types include high volatility, low volatility, low stability and high stability, and the scores of each signal connection type are: [0, 0.3), [0.3, 0.5), [0.5, 0.7), and [0.7, 1.0]. Here, the first signal threshold is 0.3, the second signal threshold is 0.5, and the third signal threshold is 0.7.

[0131] Exemplarily, Xiao Zhang's structural connection data is imported into the signal connection classification model, and it is calculated that when Xiao Zhang uses the portable WIFI, his signal connection type is low volatility, that is, the score calculated by the signal connection classification model is in the interval of [0.3, 0.5).

[0132] It is understandable that the preset first signal threshold, second signal threshold and third signal threshold are affected by the environment (such as the number of obstacles, humidity) and the portable WIFI model, and the first signal threshold < the second signal threshold < the third signal threshold.

[0133] It should be explained that the channel refers to the communication channel and the medium for signal transmission. Exemplarily, in the channel option in the WIFI advanced settings interface, different channels (such as 1 to 13) can be selected. Use a WIFI analysis tool (such as WIFIAnalyzer) to view the channel usage of the surrounding network, where channel 1, channel 3, and channel 11 are less used channels. Therefore, when using signal 1, channel 3 and channel 1, interference can be avoided. Therefore, channel 1 is set as the first channel, channel 3 as the second channel, and channel 11 as the third channel. In terms of the degree of avoiding interference, the first channel, the second signal, and the third channel are ranked as follows: the third channel < the second channel < the first channel.

[0134] It should be understood that viewing the channel usage of surrounding networks and setting channels through a WIFI analysis tool is a prior art and will not be described in detail here.

[0135] S5. While activating the target portable WIFI using the signal constraint model, generate a temporary connection password according to the MAC address of the WIFI user device, and send the temporary connection password to the WIFI user device.

[0136] In detail, the step of generating a temporary connection password according to the MAC address of the WIFI user device includes:

[0137] A temporary connection password is obtained using a pre-built combination rule and a MAC address, wherein the combination rule is: the preset WIFI password is used as the first password of the temporary connection password, the last three characters of the MAC address are used as the second password of the temporary connection password, and the temporary connection password is generated by sorting the first and second passwords.

[0138] It should be explained that the temporary connection password is a time-limited password. During a period of time, the WIFI user device can use this password to connect to the portable WIFI.

[0139] Exemplarily, after the signal constraint model is generated, the signal constraint model can be imported into the control APP of the portable WIFI, and the portable WIFI can be controlled by the APP to transmit the signal of a specific channel based on the signal constraint model. After the import is successful, the portable WIFI can be activated, and a temporary password dedicated to the device can be generated according to its device information, waiting for the WIFI user device to connect to the WIFI signal.

[0140] For example, the WIFI password is: 66668888, and the last three characters of the MAC address are: 1, 2 and 3 respectively, then the generated temporary connection password is: 66668888123.

[0141] S6. After the WIFI user device successfully connects to the target portable WIFI using the temporary connection password, a signal connection record of the WIFI user device is obtained, and an average fluctuation rate is calculated using the signal connection record.

[0142] Specifically, when the WIFI user device successfully connects to the target portable WIFI using the temporary connection password, the signal connection record of the WIFI user device is obtained, and the average fluctuation rate is calculated using the signal connection record, including:

[0143] When the WIFI user device successfully connects to the target portable WIFI using the temporary connection password, the signal connection record during the use is obtained by using the WIFI user device, wherein the signal connection record includes: x update fluctuation rates and x update fluctuation times, and the update fluctuation rates correspond to the update fluctuation times one by one;

[0144] The average fluctuation rate is calculated using x update fluctuation rates and x update fluctuation times. The calculation formula is as follows:

[0145]

[0146] in, is the average fluctuation rate, v i is the ith update fluctuation rate among the x update fluctuation rates, t i is the i-th update fluctuation time among x update fluctuation times, where 1≤i≤x, and i and x are integers.

[0147] It should be explained that the update fluctuation time and update fluctuation rate refer to the duration of each fluctuation of the portable WIFI signal and the network speed value at the beginning of each fluctuation during the use of the portable WIFI after the WIFI user device successfully connects to the portable WIFI. Under normal circumstances, the duration of the fluctuation signal is short, and the network speed value in the fluctuation signal varies more complexly. Therefore, in the embodiment of the present invention, only the network speed value at the beginning of the fluctuation is taken as the update fluctuation rate. The size of the average fluctuation rate can reflect the average value of the network speed when the signal is in a fluctuating state during the use of the portable WIFI.

[0148] S7. Calculate signal adjustment parameters using the average fluctuation rates corresponding to n WIFI user devices, use the signal adjustment parameters to update n signal constraint models in the target portable WIFI, obtain n signal adjustment models, use the n signal adjustment models to control the network signal transmitted by the target portable WIFI, and complete the signal adjustment of the portable WIFI.

[0149] Specifically, the method of calculating the signal adjustment parameter using the average fluctuation rate corresponding to the n WIFI user devices and updating the n signal constraint models in the target portable WIFI using the signal adjustment parameter to obtain the n signal adjustment models includes:

[0150] The formula for calculating the signal adjustment parameter is as follows:

[0151]

[0152] Where μ is the signal adjustment parameter, is the average fluctuation rate of the jth WIFI user equipment among n WIFI user equipments, where 1≤j≤n, and j and n are integers;

[0153] The signal adjustment parameters and the connection peak factor are used to calculate the updated peak factor. The calculation formula is as follows:

[0154] M0=M·μ

[0155] Among them, M0 is the update peak coefficient;

[0156] The connection peak coefficients in the n signal constraint models are all replaced by the update peak coefficients to obtain n signal adjustment models.

[0157] It should be understood that the signal adjustment parameter integrates the average fluctuation rate corresponding to n WIFI user devices, and calculates it with the original connection peak coefficient to obtain a parameter that is more in line with the signal state after connecting to the portable WIFI, which is the updated peak coefficient. Therefore, by replacing the connection peak coefficient in the original signal constraint model with the updated peak coefficient, the updated portable WIFI is more in line with the current situation, thereby improving the optimization of network performance, and further improving the user experience when using the portable WIFI.

[0158] The present invention is to solve the problem described in the background technology. The present invention receives a WIFI adjustment instruction and confirms a signal adjustment environment according to the WIFI adjustment instruction, wherein the signal adjustment environment includes: a power supply, n WIFI user devices, a WIFI carrier device and a portable WIFI, wherein 2≤n≤m, and n is an integer, and m is a preset connection threshold. The portable WIFI will send different network signals according to different WIFI user devices. It can be seen that the embodiment of the present invention ensures the smooth operation of all devices by constructing a complete signal adjustment environment, and provides an environment that is more in line with practical applications for subsequent signal adjustment links; WIFI user devices are extracted from the n WIFI user devices in sequence, and the extracted WIFI The user device performs the following operations: receiving the signal connection instruction initiated by the extracted WIFI user device, sending the signal connection instruction to the WIFI carrier device, and when the WIFI carrier device successfully receives the signal connection instruction, obtaining the device information of the WIFI user device, wherein the device information includes: MAC address, two-dimensional position coordinates. It can be seen that the embodiment of the present invention considers the differences between WIFI user devices before processing each WIFI user device, and then different device information can be obtained according to different WIFI user devices, laying a foundation for providing high-quality network signals for WIFI user devices more accurately in the future; using the two-dimensional position coordinates and the pre-acquired portable WIFI The simulated signal distance is calculated by the position coordinates, and the simulated signal distance is used to set the signal transmission frequency band of the portable WIFI to obtain the target portable WIFI. It can be seen that the embodiment of the present invention optimizes the signal transmission frequency band by simulating the signal distance to ensure that each WIFI user device can receive the most suitable network signal and realize automatic signal adjustment; the historical connection record of the WIFI user device is obtained, and a signal constraint model of the WIFI user device is generated according to the historical connection record. The historical connection data is used to analyze the usage mode and demand of the WIFI user device to generate a personalized signal constraint model, so that the signal adjustment is more intelligent and accurate to meet the needs of different WIFI user devices; the signal constraint model is used to activate the target portable WIFI At the same time, a temporary connection password is generated according to the MAC address of the WIFI user device, and the temporary connection password is sent to the WIFI user device. According to the MAC addresses of different WIFI user devices, a temporary connection password unique to each WIFI user device is generated to ensure the security and convenience of the connection; when the WIFI user device successfully connects to the target portable WIFI using the temporary connection password, the signal connection record of the WIFI user device is obtained, and the average fluctuation rate is calculated using the signal connection record. By recording the signal connection data after the connection in real time, the signal connection stability and fluctuation of the device during the use of the portable WIFI are monitored, and the average fluctuation rate is calculated to provide data support for subsequent signal adjustments;The signal adjustment parameters are calculated using the average fluctuation rates corresponding to n WIFI user devices, and the n signal constraint models in the target portable WIFI are updated using the signal adjustment parameters to obtain n signal adjustment models. The network signals transmitted by the target portable WIFI are controlled using the n signal adjustment models to complete the signal adjustment of the portable WIFI. By integrating the average fluctuation rates of multiple devices, the previous signal constraint model is readjusted to obtain a signal adjustment model that is more in line with the current connection state, and the signal channel allocation is readjusted through the signal adjustment model to ensure that each WIFI user device can obtain the best network performance. Therefore, the present invention can realize intelligent optimization of network performance. ;
