The specific flow shown in FIG. 2 will be described in detail below.

Step S110: Obtain the first firmware version number information stored in the target server.

In this embodiment, the target wireless network device may first obtain the first firmware version number information stored by the target server. Wherein, there is a corresponding relationship between the first firmware version number information and the target firmware installed on the target wireless network device. For example, the first firmware version number information may be information of the latest version of the target firmware.

Step S120: Determine whether to update the target firmware based on the first firmware version information and the second firmware version information of the target firmware installed on the target wireless network device.

In this embodiment, after obtaining the first firmware version number information based on step S110, the target wireless network device may, based on the first firmware version number information and the target firmware installed on the target wireless network device, The second firmware version number information is used to determine whether to update the target firmware.

The second firmware version number information is the version number information of the target firmware currently installed on the target wireless network device. That is, whether to update the firmware is determined based on the current version of the firmware installed on the target wireless network device and the latest version of the firmware stored on the target server. And, if it is determined that the target firmware needs to be updated, step S130 is executed.

Step S130: Acquire the updated firmware corresponding to the first firmware version number information from the target server.

In this embodiment, after it is determined based on step S120 that the target firmware needs to be updated, the target wireless network device may acquire the updated firmware corresponding to the first firmware version number information from the target server.

Wherein, the update firmware and the target firmware belong to different versions of the same wireless network device firmware.

Step S140, performing an update operation on the target firmware based on the update firmware.

In this embodiment, after acquiring the update firmware based on step S130, the target wireless network device may perform an update operation on the target firmware based on the update firmware.

Based on the above method, by comparing the firmware version number information of the target firmware on the target wireless network device with the corresponding firmware version number information stored on the target server, it is determined whether to update the target firmware, so that when it is determined that the target firmware needs to be updated During the update, the update firmware corresponding to the first firmware version number information is obtained from the target server, and an update operation is performed on the target firmware based on the update firmware. Based on this, the automatic update of the firmware of the wireless network device can be realized through the judgment of the wireless network device, which can effectively reduce the cost of the update and improve the efficiency of the update, thereby improving the update process of the wireless network device in the prior art. less efficient problem.

It can be understood that, in the above example, firmware may refer to a program written in an erasable and programmable read-only memory (EPROM) or an electrically erasable and programmable read-only memory (EEPROM), such as an electronic device. The device "drivers" are stored internally, and the operating system of the electronic device needs to be fully driven by firmware, for example, the firmware may include the Basic Input/Output System (BIOS, Basic Input/Output System) on the motherboard of the electronic device.

In the first aspect, it should be noted for step S110 that the specific manner of acquiring the first firmware version number information is not limited, and may be selected according to actual application requirements.

For example, in an alternative example, the first firmware version number information can be obtained based on the following steps:

First, obtain the time information of the last time the target wireless network device performs the update operation (that is, the time information of the last time the update operation was performed), obtain the corresponding historical time information, and calculate the difference between the historical time information and the current time information to obtain the corresponding time length information;

Next, determine whether the time length information is greater than the preset time length threshold information (wherein, the time length threshold information can be generated based on the configuration operation performed by the user according to the actual application scenario);

Then, if the time length information is greater than the time length threshold information, generate version number request information, and send the version number request information to the target server, where the target server is used to generate version number request information based on the version number The request information sends the stored first firmware version number information corresponding to the target firmware to the target wireless network device;

Finally, the first firmware version number information sent by the target server is received.

In the second aspect, it should be noted for step S120 that the specific manner of determining whether to update the target firmware based on the first firmware version number information and the second firmware version number information is not limited, and may be determined according to actual applications. needs to choose.

For example, in an alternative example, whether to update the target firmware may be determined based on the following steps:

First, determine whether the first firmware version information is the same as the second firmware version information of the target firmware installed on the target wireless network device (wherein, the first firmware version information is stored on the target server). The latest version number of the wireless network device firmware, the second firmware version number information is the latest version number of the wireless network device firmware installed on the target wireless network device);

Secondly, if the first firmware version number information and the second firmware version number information are the same, it is determined that the target firmware is not to be updated (that is, the wireless network device installed on the target wireless network device is determined not to be updated). When the firmware is the latest version, it can be determined not to update the firmware of the wireless network device).

On the basis of the above example, it should be noted that in step S120, if the first firmware version number information and the second firmware version number information are different, the specific processing method is not limited.

For example, in an alternative example, if the first firmware version number information and the second firmware version number information are different, it is determined that the target firmware needs to be updated.

That is, as long as it is determined that the wireless network device firmware installed on the target wireless network device is not the latest version, the wireless network device firmware needs to be updated.

For another example, in another alternative example, if the first firmware version number information and the second firmware version number information are different, the corresponding update of the first firmware version number information is obtained from the target server. The firmware difference degree between the firmware and the target firmware corresponding to the second firmware version number information, wherein the firmware difference degree is used to represent the difference between the update firmware and the target firmware in multiple dimensions, and the multiple The dimensions include a data volume dimension, a program logic dimension, and a program content dimension; and whether to update the target firmware is determined based on the firmware difference degree.

The difference in the dimension of the data volume may refer to the difference between the quantities of the update firmware and the target firmware. For example, if the data volume of the update firmware is 1.1G, the target firmware has a The data volume is 0.98G, so the difference in the data volume dimension is 0.12G.

The difference in the program logic dimension may refer to the difference between the sequence relationship between the update firmware and the target firmware in each program segment. For example, in the update firmware, step A is performed first, and then step B is performed. step; firstly execute the B step in the target firmware, and then execute the A step. In this way, the number of program segments that store the opposite execution logic can be counted, and the number can be used as the difference in the dimension of the program logic;

The difference in the dimension of the program content may refer to a ratio between the data amount of different program contents between the update firmware and the target firmware and the total data amount of the update firmware. For example, the data amount of the updated firmware is X, and the data amount of a program that is different from the target firmware is Y, and the corresponding difference is Y/X.

The firmware difference degree may refer to performing weighting calculation after normalizing the differences in the above-mentioned multiple dimensions respectively. Among them, the weight coefficients corresponding to the differences in different dimensions can be generated based on the configuration operations performed by the user according to the actual application scenario, and if the data volume dimension is more inclined, the weight coefficients of the differences in the data volume dimension can be greater than the differences in other dimensions. If it is more inclined to the program content dimension, the weight coefficient of the difference in the program content dimension can be larger than the weight coefficient of the difference in other dimensions.

Optionally, in the above example, the specific manner of determining whether to update the target firmware based on the firmware difference is not limited, and may be selected according to actual application requirements.

For example, in an alternative example, the following steps may be performed to determine whether to update the target firmware based on the firmware difference:

First, determine whether the firmware difference degree is greater than a preset difference degree threshold;

Secondly, if the firmware difference degree is less than or equal to the difference degree threshold, it is determined not to update the target firmware; if the firmware difference degree is greater than the difference degree threshold, an update confirmation notification message is generated, and it is determined whether acquiring update confirmation information generated in response to the update confirmation operation performed by the target user based on the update confirmation notification information;

Then, if the update confirmation information is obtained, it is determined that the target firmware needs to be updated; if the update confirmation information is not obtained, it is determined not to update the target firmware (that is, in the firmware When the difference degree is greater than the difference degree threshold, it may be determined whether to update the target firmware based on user requirements).

It can be understood that, in the above example, the manner of generating the difference threshold is not limited, and can be selected according to actual application requirements.

For example, in an alternative example, the difference threshold may be generated based on a user's configuration operation. For another example, in another alternative example, the difference threshold can be generated based on the following steps to reduce labor costs:

First, obtain a plurality of pieces of difference degree record information, wherein each piece of the difference degree record information is used to generate each time in history whether to update the target firmware based on the firmware difference degree, and the difference degree record The information is used to represent whether it is determined that the target firmware needs to be updated when the firmware difference degree is greater than the difference degree threshold;

Secondly, performing correction processing on the preset initial difference degree threshold based on the plurality of difference degree record information to obtain the difference degree threshold value, wherein the difference degree initial threshold value is generated based on the target server performing an initial threshold value operation (such as Generated based on the configuration operation of the administrator of the target server, or a randomly generated value).

It can be understood that, in the above example, the specific manner in which the difference degree threshold is obtained by performing correction processing on the difference degree initial threshold is not limited, and can be selected according to actual application requirements.

For example, in an alternative example, the difference degree threshold may be obtained by modifying the initial difference degree threshold based on the following steps:

The first step is to sequentially use each of the plurality of difference degree record information as the difference degree record information to be processed, and calculate the difference between the to-be-processed difference degree record information and each other difference degree record information. Time correlation information in the time dimension (that is, the time correlation in the time dimension between each two difference degree records in the plurality of difference degree records can be calculated, such as the correlation between the generation times wherein, in one example, the reciprocal of the difference between the generation times can be used as the time correlation information, that is, the larger the difference between the generation times, the smaller the corresponding time correlation information; in another In an example, the weighted value of the inverse of the difference between the generation times and the inverse of the difference between the corresponding period information can be used as the corresponding time correlation information, for example, each day can be divided into 12 periods. , such as the first period, the second period, ..., the twelfth period);

In the second step, for each piece of the difference degree record information to be processed, based on the time correlation information between the to-be-processed difference degree record information and each other piece of difference degree record information, perform sorting processing on each piece of other difference degree record information , constitute an ordered set of difference degree record information corresponding to the difference degree record information to be processed (for example, the ordered set of difference degree record information may be "difference degree record information 1, difference degree record information 3, difference degree record information 5, Difference degree record information 2, difference degree record information 4") to obtain a plurality of ordered sets of difference degree record information, wherein, in the ordered set of difference degree record information, the time corresponding to the previous difference degree record information The correlation is greater than the time correlation corresponding to the difference degree record information after the sorting;

The third step is to calculate, for each piece of the difference degree record information to be processed, an ordered set of difference degree record information corresponding to the to-be-processed difference degree record information and an ordered set of difference degree record information corresponding to each other difference degree record information The set similarity information between the two sets of similarity information is obtained, and multiple set similarity information corresponding to the difference degree record information to be processed is obtained (for example, for set A, the set similarity information between set A and set B can be calculated, and the set similarity between set A and set A can be calculated. Set similarity information between sets C, calculation set similarity information between sets A and D);

The fourth step, for each piece of the difference degree record information to be processed, perform discrete value calculation on the plurality of set similarity information corresponding to the to-be-processed difference degree record information (for example, for similarity information a, similarity information b and similarity information c, you can first calculate the average value of a, b and c to get d, so you can first calculate the absolute value of the difference between a and d, the absolute value of the difference between b and d, and the difference between c and d. The sum of the absolute values of the difference values, and then divide the sum value by 3 to obtain the corresponding discrete value), and obtain the set similarity discrete information corresponding to the difference degree record information to be processed;

The fifth step, based on the set similarity discrete information, determine the target pending difference degree record information from the multiple pieces of the pending difference degree record information (for example, the pending difference degree with the smallest set similarity discrete information can be determined. record information, as the target difference degree record information to be processed), and determine the orderly collection of the difference degree record information corresponding to the target difference degree record information to be processed as the target difference degree record information ordered collection, and based on the target difference degree record information. The processing difference degree record information updates the ordered set of target difference degree record information (for example, the target to-be-processed difference degree record information can be inserted into the ordered set of target difference degree record information, because the difference The time correlation corresponding to the difference degree record information sorted earlier in the ordered set of degree record information is greater than the time correlation corresponding to the difference degree record information that is sorted later. Therefore, the target difference degree record information to be processed can be inserted into the the first position of the set);

The sixth step is to perform a weight coefficient determination process on each piece of the difference degree record information based on the sorted position of the ordered set of the updated target difference degree record information, and obtain a weight coefficient corresponding to each piece of difference degree record information, wherein, The weight coefficient of the difference degree record information has a positive correlation with the corresponding time correlation information (that is, the higher the sorting position is, the larger the corresponding time correlation information is, and the corresponding weight coefficient may be larger; wherein , the sum of each weight coefficient can be 1);

The seventh step is to assign a first value (such as 1) to the difference degree record information representing that the target firmware needs to be updated when the degree of difference of the firmware is greater than the threshold of the degree of difference. When the difference degree is greater than the difference degree threshold, it is determined that the difference degree record information that does not need to be updated to the target firmware is assigned a second value (such as -1);

The eighth step is to perform a weighted sum calculation based on the assignment (such as the first numerical value or the second numerical value) and the weight coefficient corresponding to each piece of difference degree record information in the updated target difference degree record information ordered set, get the calculation result;

The ninth step, based on the magnitude relationship between the calculation result and the first numerical value and the second numerical value, perform a correction process on the preset difference degree initial threshold value to obtain the difference degree threshold value (for example, in the When the first numerical value is 1 and the second numerical value is -1, if the calculation result is greater than 0, the initial threshold value of the difference degree can be reduced to obtain the difference degree threshold value, such as reducing by 10%; If it is less than or equal to 0, the initial threshold of the degree of difference can be increased to obtain the threshold of the degree of difference, such as an increase of 10%).

It can be understood that, in the above example, the specific method of calculating the set similarity information between the ordered sets of the difference degree record information is not limited, and can be selected according to actual application requirements.

For example, in an alternative example, the set similarity information between the ordered sets of difference record information can be calculated based on the following steps:

In the first step, for each two ordered sets of difference degree record information in the plurality of ordered sets of difference degree record information, the two ordered sets of difference degree record information are respectively regarded as the first order of difference degree record information. The set and the second degree of difference record information ordered set;

In the second step, based on the characterization value (such as the first value and the second value described above) corresponding to each difference degree record information in the ordered set of the first difference degree record information, obtain the corresponding first characterization value in order collection, and based on the characterization value corresponding to each difference degree record information in the second difference degree record information ordered set, a corresponding second characterization value ordered set is obtained, wherein the characterization value is based on the difference degree record The content of the information representation is determined, and the representation value corresponding to the difference degree record information with the same representation content is the same, and the representation value corresponding to the difference degree record information with different representation content is different;

The third step is to compare the first ordered set of characterization values with the second ordered set of characterization values to obtain a corresponding ordered set of characterization values compared, wherein the characterization value comparison ordered set is used to represent Whether the first characterization values at the corresponding sorting positions between the first ordered set of characterization values and the second ordered set of characterization values are the same (for example, the first ordered set of characterization values and the second ordered set of characterization values have The characterization value of the corresponding position in the ordered set is the same, and the parameter of the characterization value compared to the corresponding position in the ordered set is 1; , the parameter of the corresponding position in the characterization value is 0 compared to the ordered set);

The fourth step is to analyze the characterization value comparison ordered set to obtain characterization value comparison feature information corresponding to the characterization value comparison ordered set, wherein the characterization value comparison feature information is used to characterize the first characterization value Similarity information between the ordered set and the second ordered set of characteristic values (for example, the characteristic value can be compared with the number of first parameters in the ordered set and the characteristic value compared with all parameters in the ordered set The ratio of the number of s is used as the characteristic value contrast characteristic information, and the first parameter indicates that the standard value of the corresponding position in the ordered set of the first characteristic value and the ordered set of the second characteristic value is the same);

Step 5: Based on the characteristic value comparison feature information, obtain the set similarity information between the corresponding ordered set of first degree of difference record information and the corresponding ordered set of second degree of difference record information (for example, you can directly The characterization value is compared with the feature information as the set similarity information).

For another example, in another alternative example, the set similarity information between the ordered sets of difference record information can be calculated based on the following steps:

In the first step, for each two ordered sets of difference degree record information in the plurality of ordered sets of difference degree record information, the two ordered sets of difference degree record information are respectively regarded as the first order of difference degree record information. The set and the second degree of difference record information ordered set;

The second step is to sequentially determine each piece of the difference degree record information in the ordered set of the first difference degree record information as the target difference degree record information;

The third step is to compare the target difference degree record information with the difference degree record information of the corresponding position in the ordered set of the second difference degree record information based on the content of the representation (for example, the target difference degree record information is the first piece of difference record information in the ordered set of the first difference degree record information, then the content represented by the target difference degree record information and the first piece of the second difference degree record information in the ordered set The content represented by the difference degree record information is compared to determine whether the content represented by the two difference degree record information is the same);

The fourth step is to count the number of the target difference degree record information with the same content as the difference degree record information of the corresponding position in the ordered set of the second degree of difference record information, to obtain the first number, and based on the first number and the second quantity of the difference degree record information included in the first difference degree record information ordered set to obtain the corresponding first ratio value (for example, there are 5 difference degree records in the first difference degree record information ordered set. information, among which, there are 3 pieces of difference degree record information and the difference degree record information of the corresponding position in the second ordered set of difference degree record information have the same representation content, and the corresponding first ratio value is 3/5);

The fifth step is to determine at least one target value less than or equal to the second number, wherein each of the target values is greater than 1 and is an integer (for example, if the second number is 5, it can be between 2, 2, One or more of 3, 4 and 5 are arbitrarily selected, wherein, the higher the accuracy requirement, the larger the number of selected target values, and the smaller the amount of calculation required, the smaller the number of selected target values);

The sixth step, for each of the target values, successively determine each successive piece of the difference degree record information in the first difference degree record information ordered set as the difference degree record information ordered subset ( For example, the first difference degree record information is "Information 1, Information 2, Information 3, Information 4", and the target value is 3, then the ordered subset of difference degree record information may include "Information 1, Information 2. Information 3", "Information 2, Information 3, Information 4");

The seventh step, based on the content of the representation, compare the ordered subset of the difference degree record information with the continuous difference degree record information of the target value bar at the corresponding position in the second ordered set of difference degree record information. (For example, based on the foregoing example, if the ordered subset of the difference degree record information is "Information 1, Information 2, Information 3", then the second degree of difference records the first difference in the ordered set of information. The difference degree record information, the second difference degree record information and the third difference degree record information are compared, and only the content represented by the information 1 and the first difference degree record information is the same, and the information 2 and the second difference degree record information. When the content represented by the record information is the same, and the content represented by the information 2 and the third difference degree record information are the same, it is determined that "Information 1, Information 2, and Information 3" are in the ordered set of the second difference degree record information. The first discrepancy record information, the second discrepancy record information and the third discrepancy record information have the same content);

The eighth step, for each of the target values, count the difference degree record information that is the same as the content of the difference degree record information represented by the continuous difference degree record information of the target value bar at the corresponding position in the second difference degree record information ordered set. The number of ordered subsets, the third number corresponding to the target value is obtained, and the second proportional value corresponding to the target value is obtained based on the third number (for example, on the basis of the above example, the target value is 3, if the representation The number of ordered subsets of difference degree record information with the same content is 1, and the total number of ordered subsets of difference degree record information is 2, then the corresponding second ratio is 1/2);

The ninth step is to perform weighted calculation based on the first proportional value and the second proportional value corresponding to each of the target values to obtain the ordered set of the first difference degree record information and the second difference degree record. Set similarity information between ordered sets of information, wherein the weight coefficient corresponding to the second scale value is greater than the weight coefficient corresponding to the first scale value, and the weight coefficients of the second scale values corresponding to different target values are different, And there is a positive correlation between the weight coefficient corresponding to the second scale value and the corresponding target value (for example, on the basis of the above example, the first scale value is 0.6, the corresponding weight coefficient is 0.4, and the second scale value is 0.4. is 0.5, and the corresponding weight coefficient is 0.6, then the set similarity information is 0.54).

For another example, in another alternative example, the set similarity information between the ordered sets of difference record information can be calculated based on the following steps:

First, for every two ordered sets of difference degree record information in the plurality of ordered sets of difference degree record information, the two ordered sets of difference degree record information are respectively used as the corresponding first difference degree record information: an ordered set and an ordered set of record information of the second degree of difference;

In the second step, for each of the corresponding ordered sets of difference degree record information, determine the first ordered subset of record information of each of the two ordered sets of difference degree record information in the two ordered sets of difference degree record information and The second ordered subset of record information (that is, to determine the ordered subset of first record information and the second ordered subset of record information of the ordered set of first degree of difference record information, and to determine the second degree of difference record The first ordered subset of record information and the second ordered subset of record information of the ordered set of information);

Step 3: For each two corresponding ordered sets of difference degree record information, determine a third degree of difference formed by the corresponding ordered set of first difference degree record information and the second order set of difference degree record information. The ordered set of record information (for example, the union of the difference degree record information in the ordered set of the first difference degree record information and the difference degree record information in the ordered set of the second difference degree record information can be obtained to obtain Record information union, and then calculate the time correlation information of each difference degree record information in the first difference degree record information ordered set and the second difference degree record information ordered set in the record information union Then, based on the size relationship of the average value information, sort each difference degree record information in the record information union to obtain the third difference degree record information ordered set, such as the difference degree record in the first order. The average information corresponding to the information is larger);

The fourth step is to determine, for each ordered set of third degree of difference record information, a third ordered subset of record information and a fourth ordered subset of record information of the ordered set of third degree of difference record information, wherein , the first ordered subset of record information and the second ordered subset of record information are complementary sets in the corresponding ordered set of difference degree record information, and the third ordered subset of record information and all The fourth ordered subset of record information is complementary to each other in the corresponding ordered set of difference degree record information, and the first ordered subset of record information and the third ordered subset of record information are based on the same Sampling rule sampling (for example, in the corresponding ordered set of difference degree record information, odd-digit difference degree record information can be formed into the first record information ordered subset or the third record information ordered subset. gather);

Step 5: According to the first ordered subset of record information of each of the ordered sets of difference degree record information and the corresponding ordered subset of third record information of the ordered set of third degree of difference record information, calculate The first correlation value of the ordered set of difference degree record information, wherein the first correlation value is used to represent the relationship between the ordered subset of the first record information and the ordered subset of the third record information. connection relation;

The sixth step is to calculate according to the second ordered subset of record information of each of the ordered sets of difference degree record information and the corresponding ordered subset of fourth record information of the ordered set of third degree of difference record information. The second correlation value of the ordered set of difference degree record information, wherein the first correlation value is used to represent the relationship between the ordered subset of the second record information and the ordered subset of the fourth record information. connection relation;

The seventh step is to perform weighted calculation on the first correlation value and the second correlation value of each ordered set of difference degree record information based on a predetermined weight coefficient, to obtain the ordered set of difference degree record information and the The third degree of difference records the set similarity information between the ordered sets of information (it can be understood that the weight coefficient can be generated based on the configuration operation performed by the user according to the actual application scenario, and its specific value is not limited, as long as the The sum of the weight coefficients of the first associated value and the second associated value is 1);

The eighth step, for each two corresponding ordered sets of difference degree record information, calculate each ordered set of difference degree record information included in the two ordered sets of difference degree record information and the corresponding third difference degree record. The average value of the set similarity information between the ordered sets of information is obtained, and the average value between the ordered set of the first and the second ordered set of record information of the difference degree included in the two ordered sets of difference degree record information is obtained. Set similarity information (for example, adding the set similarity information between the ordered set of the first difference degree record information and the ordered set of the third difference degree record information plus the second difference degree record information in an orderly manner. The set similarity information between the set and the ordered set of the third degree of difference record information is divided by 2 to obtain the ordered set of the first degree of difference record information and the ordered set of the second degree of difference record information set similarity information between).

It can be understood that, in the above example, the specific manner of calculating the first correlation value of the ordered set of difference degree record information is not limited, and can be selected according to actual requirements.

For example, in an alternative example, the first associated value of the ordered set of difference record information may be calculated based on the following steps:

First, calculate the standard deviation of the first ordered subset of record information in the ordered set of difference degree record information (that is, calculate the standard deviation of the characterization values of each difference degree record information in the first ordered subset of record information, the characterization value as described above), and calculate the standard deviation of the ordered subset of the third record information of the ordered set of the third degree of difference record information (that is, to calculate the difference of the degree of difference record information in the ordered subset of the third record information standard deviation of the characterization value);

Next, calculate the covariance of the first ordered subset of record information of the ordered set of difference degree record information and the third ordered subset of record information of the ordered set of third degree of difference record information (that is, to calculate the first the covariance between the characteristic value of the record information of each degree of difference in the ordered subset of record information and the characteristic value of the record information of each degree of difference in the ordered subset of the third record information);

Then, according to the standard deviation of the ordered subset of the first record information, the standard deviation of the ordered subset of the third record information, and the ordered subset of the first record information and the third record information are ordered The covariance of the subsets is calculated, and the first correlation value of the ordered set of difference record information is calculated (for example, two standard deviations and the mean of the covariance can be calculated, and then the first correlation value can be obtained based on the mean, wherein, There is a negative correlation between the mean value and the first associated value, for example, the inverse of the absolute value of the value is taken as the first associated value).

It can be understood that, in the above example, the specific manner of calculating the second correlation value of the ordered set of difference degree record information is not limited, and can be selected according to actual application requirements.

For example, in an alternative example, if it is determined that the target firmware needs to be updated, request information may be generated first, where the request information may carry the first firmware version number information. Then, the request information is sent to the target server, so that the target server can update the firmware corresponding to the first firmware version number information to the target wireless network device based on the request information.
