Detailed Description
The technical solution of the present application is further elaborated below with reference to the drawings and the embodiments.
In this embodiment, a network architecture is provided first, and fig. 1 is a schematic view of a composition structure of the network architecture in the embodiment of the present application, as shown in fig. 1, the network architecture includes a plurality of terminals 11 to 1N, a plurality of APs 21 to 2M, and a wireless network 31, where the terminals 11 to 1N establish a connection with one AP of the APs 21 to 2M, so as to access the wireless network 31, and implement data interaction with the wireless network 31. Generally, a terminal may be various types of devices having the capability of reconnecting an AP, for example, the terminal may include a mobile phone, a tablet, a desktop, a personal digital assistant, a navigator, a digital phone, a video phone, a television, a sensing device, and the like, and may further include a personal computer, a server, a network device, and the like. Note that, in the art, the terminal is also referred to as an STA.
The embodiment provides a method for reconnecting an AP, the method is applied to a terminal, the functions implemented by the method can be implemented by a processor in the terminal calling a program code, of course, the program code can be stored in a computer storage medium, and the terminal at least comprises the processor and the storage medium.
Fig. 2 is a schematic flow chart illustrating an implementation process of a method for reconnecting an AP according to an embodiment of the present application, as shown in fig. 2, the method includes steps S201 to S204:
s201, if the AP needs to be reconnected, obtaining values of at least two connection parameters of each candidate AP in a candidate AP set obtained by scanning; the connection parameters are parameters that affect the stability of the connection between the terminal and the corresponding candidate AP;
for example, if the signal strength (i.e., the received signal strength) of a signal transmitted by the current serving AP received by the terminal is less than a preset strength threshold, it is determined that an AP needs to be reconnected, and the reconnected AP is generally another AP except the current serving AP; for another example, if the terminal receives the Deauth packet, it is determined that the AP needs to be reconnected.
It is understood that the parameters affecting the connection stability between the terminal and the corresponding candidate AP generally include at least two of the following: the working frequency of the candidate AP, the received signal strength when the terminal receives the signal sent by the candidate AP, the first power forming rate of data transmission between the terminal and the candidate AP, the data transmission speed of the candidate AP and the second power forming rate of the terminal connected with the candidate AP; wherein the received signal strength is a main parameter affecting connection stability between the terminal and a corresponding AP.
S202, converting the numerical value of each connection parameter of each candidate AP into a corresponding score value according to a corresponding conversion rule;
it should be noted that, because different connection parameters have different degrees of influence on the connection stability between the corresponding AP and the terminal, for example, the received signal strength and the operating frequency of the candidate AP are main parameters influencing the connection stability. Therefore, in practical applications, the conversion rule configured for each connection parameter is generally different, that is, each connection parameter has a corresponding conversion rule.
S203, determining a target AP from the candidate AP set based on the score value of each connection parameter of each candidate AP;
it is understood that the higher the score value, the stronger the connection stability between the corresponding AP and the terminal. In other embodiments, the total score value of the corresponding candidate AP may be determined based on the score value of each connection parameter of each candidate AP, and then the target AP may be determined from the candidate AP set based on the total score value of each candidate AP, for example, the candidate AP with the highest total score value may be determined as the target AP. In this way, the terminal can obtain better connection link quality after establishing connection with the target AP.
S204, sending a connection request to the target AP, wherein the connection request is used for requesting to establish connection with the target AP.
In the embodiment of the application, the target AP is selected from the candidate AP set based on the score values of the plurality of connection parameters of each candidate AP, so that the terminal can obtain better connection link quality after establishing connection with the target AP.
The embodiment of the present application provides another method for reconnecting an AP, where the method is applied to a terminal, and the method includes steps S301 to S306:
s301, pre-loading a score mapping table corresponding to each connection parameter, wherein the score mapping table is used for recording a preset range to which the numerical value of the corresponding connection parameter belongs and a score value corresponding to the preset range;
since different connection parameters have different degrees of influence on the connection stability between the corresponding AP and the terminal, when a corresponding score mapping table is configured for each connection parameter, the configuration ranges of the score values are different. For example, fig. 3 is a score mapping table corresponding to each connection parameter in the embodiment of the present application, as shown in fig. 3, table 301 is a score mapping table corresponding to the operating frequency, table 302 is a score mapping table corresponding to the received signal strength, table 303 is a score mapping table corresponding to the first power component, table 304 is a score mapping table corresponding to the data transmission speed, and table 305 is a score mapping table corresponding to the second power component.
As can be seen from fig. 3, the configuration range of the score value corresponding to the working frequency is 90-100 points, wherein the lowest score of the working frequency is 90 points; the configuration range of the score value corresponding to the received signal strength is 70-90 minutes, wherein the lowest score of the received signal strength is 70 minutes; the configuration range of the score value corresponding to the first power component is 60-70 minutes, wherein the lowest score of the first power component is 60 minutes; the configuration range of the score value corresponding to the data transmission speed is 50-60 minutes, wherein the lowest score of the data transmission speed is 50 minutes; the configuration range of the score value corresponding to the second power generation rate is 40-50 minutes, wherein the lowest score of the second power generation rate is 40 minutes; it can be seen that, the corresponding score value ranges are configured for the corresponding connection parameters according to the influence degree of each connection parameter on the connection stability between the terminal and the corresponding candidate AP, that is, the minimum score values configured for each connection parameter are sequentially decreased according to the order of the influence degrees from large to small. In this way, when determining the score value of each connection parameter through step S303 and step S304, it can be ensured that: the score value of the working frequency is more than or equal to the score value of the received signal strength and more than or equal to the score value of the first power component and more than or equal to the score value of the second power component, so that the score value of each connection parameter is more in line with the actual situation.
Of course, in other embodiments, the configuration ranges of the score values may also be the same, so that when the step S305 is implemented, that is, when the target AP is determined from the candidate AP set based on the score value of each connection parameter of each candidate AP, the total score value of the corresponding candidate AP needs to be determined based on the score value of each connection parameter of each candidate AP and the influence factor of the corresponding connection parameter; then, determining a target AP from the candidate AP set based on the total score value of each candidate AP; the influence factor is used for characterizing the influence degree of the corresponding connection parameter on the connection stability between the terminal and the corresponding candidate AP. For example, the influence factors sequentially allocated to the operating frequency, the received signal strength, the first power component, the data transmission speed, and the second power component are: 1.0, 0.8, 0.6, 0.4 and 0.2. In this way, when calculating the total score value of each candidate AP, the product of the score value of each connection parameter and the corresponding influence factor may be determined first, and then the sum of the products of all the connection parameters of the candidate AP may be determined as the total score value of the corresponding candidate AP.
S302, if the AP needs to be reconnected, obtaining the numerical values of at least two connection parameters of each candidate AP in the scanned candidate AP set;
s303, determining a target range to which each value belongs from the corresponding score mapping table based on the value of each connection parameter of each candidate AP;
s304, determining the score value of the corresponding connection parameter from the corresponding score mapping table based on the target range;
for example, the obtained operating frequency of the candidate AP is 5.725GHz, and as shown in fig. 3, it may be determined from the corresponding score mapping table 301 that the operating frequency belongs to the 5G frequency band, and the corresponding score value is 100 points.
Here, it should be noted that step S303 and step S304 are actually an example of implementing step S202 in the above-described embodiment.
S305, determining a target AP from the candidate AP set based on the score value of each connection parameter of each candidate AP;
s306, sending a connection request to the target AP, wherein the connection request is used for requesting to establish connection with the target AP.
The embodiment of the present application provides another method for reconnecting an AP, where the method is applied to a terminal, and the method includes steps S401 to S405:
s401, if the AP needs to be reconnected, obtaining the numerical values of at least two connection parameters of each candidate AP in a candidate AP set obtained by scanning; the connection parameters are parameters that affect the stability of the connection between the terminal and the corresponding candidate AP;
s402, converting the numerical value of each connection parameter of each candidate AP into a corresponding score value according to a corresponding conversion rule;
s403, determining a total score value of the corresponding candidate AP based on the score value of each connection parameter of each candidate AP;
here, it should be noted that, when the score mapping table corresponding to each connection parameter is configured, if the score value configuration ranges corresponding to each connection parameter are different, the sum of the score values of all the connection parameters of each candidate AP is directly determined as the total score value of the corresponding candidate AP; if the configuration range of the score value corresponding to each connection parameter is the same, the product of the score value of each connection parameter and the corresponding influence factor may be determined first, and then the sum of the products of all the connection parameters of the candidate AP is determined as the total score value of the corresponding candidate AP.
S404, determining a target AP from the candidate AP set based on the total score value of each candidate AP;
in general, the candidate AP with the highest total score value is determined as the target AP. It should be noted that step S403 and step S404 are actually an example of implementing step S203 or step S305 in the above-described embodiment.
S405, sending a connection request to the target AP, wherein the connection request is used for requesting to establish connection with the target AP.
The embodiment of the present application provides another method for reconnecting an AP, where the method is applied to a terminal, and the method includes steps S501 to S511:
s501, acquiring first sending times, wherein the first sending times are times of sending data to the candidate AP by the terminal in a preset time period;
s502, acquiring a first receiving frequency, wherein the first receiving frequency is the frequency of recording the data sent by the candidate AP received by the terminal in a preset time period;
s503, determining the first power forming rate based on the first sending times and the first receiving times;
it should be noted that the first sending times and the first receiving times are generally interaction information that has been recorded in advance by the terminal. When determining the first power contribution, these mutual information may be directly obtained, thereby determining the first power contribution. For example, a ratio of the first number of receptions to the first number of transmissions may be determined as the first power.
S504, obtaining a second sending frequency, wherein the second sending frequency is the frequency of sending a connection request to the candidate AP by the terminal in a preset time period;
s505, obtaining a second receiving frequency, wherein the second receiving frequency is the frequency of receiving the connection response sent by the candidate AP by the terminal in a preset time period;
s506, determining the second power based on the second sending times and the second receiving times;
similarly, the second sending times and the second receiving times are also interaction information that has been recorded in advance by the terminal. In determining the second power rating, such interaction information may be directly obtained to determine the second power rating. For example, the ratio of the second number of receptions to the second number of transmissions may be determined as the second power.
S507, saving the first power forming rate and the second power forming rate;
it should be noted that, in other embodiments, step S504 to step S506 may be executed first, and then step S501 to step S503 may be executed, wherein the execution sequence of step S504 and step S505 is not limited when step S504 to step S506 is executed; the execution order of step S501 and step S502 is not limited when step S501 to step S503 are executed. After the steps S501 to S507 are executed, the following steps S508 to S511 do not need to be executed immediately, and when the condition that the AP needs to be reconnected is satisfied, the steps S508 to S511 are started to be executed.
S508, if the AP needs to be reconnected, obtaining the numerical values of a plurality of connection parameters of each candidate AP in the scanned candidate AP set; wherein, the connection parameters at least include two of the following: the working frequency of the candidate AP, the received signal strength when the terminal receives the signal sent by the candidate AP, the data transmission speed of the candidate AP, the first power forming and the second power forming;
s509, converting the numerical value of each connection parameter of each candidate AP into a corresponding score value according to a corresponding conversion rule;
s510, determining a target AP from the candidate AP set based on the score value of each connection parameter of each candidate AP;
s511, sending a connection request to the target AP, wherein the connection request is used for requesting to establish connection with the target AP.
The embodiment of the present application provides another method for reconnecting an AP, where the method is applied to a terminal, and the method includes steps S601 to S608:
s601, if an attack message is received, forbidding to generate a disconnection notification, determining that the AP needs to be reconnected, and at the moment, entering the step S602; the attack message is used for blocking the connection between the terminal and the current service AP, the disconnection notification is used for notifying a user of the terminal, and the terminal and the current service AP are disconnected;
it should be noted that, in practical applications, after receiving the attack message, the procedure of generating the disconnection notification is not executed, but step S602 is directly executed, that is, the values of the at least two connection parameters of each candidate AP in the scanned candidate AP set are obtained.
Generally, the attack message is frequently sent, and particularly when the attack message is a Deauth packet, a large number of Deauth packets may cause the terminal to frequently drop, and at this time, if the terminal generates a disconnection notification after receiving the Deauth packet each time, and displays the disconnection notification on a screen of the terminal, the terminal may consume electric power of the terminal and may also affect a user sense corresponding to the terminal. Therefore, after the attack message is received, the disconnection notification is not generated for the moment, so that the power consumption of the terminal is saved, and the frequent interference to the user is avoided.
S602, obtaining values of at least two connection parameters of each candidate AP in the candidate AP set obtained by scanning; the connection parameters are parameters that affect the stability of the connection between the terminal and the corresponding candidate AP;
s603, converting the numerical value of each connection parameter of each candidate AP into a corresponding score value according to a corresponding conversion rule;
s604, determining a target AP from the candidate AP set based on the score value of each connection parameter of each candidate AP;
s605, sending a connection request to the target AP, wherein the connection request is used for requesting to establish connection with the target AP;
s606, determining whether a connection response is received within a preset time length; if yes, go to step S607; otherwise, go to step S608; wherein the connection response is used for informing the terminal that the target AP and the terminal successfully establish the connection.
It can be understood that, if the connection response is not received within the preset time period, which indicates that the connection between the terminal and the target AP is failed, then step S608 is executed, that is, a disconnection notification is generated, and the disconnection notification is output to notify the user of the terminal that the terminal and the current serving AP are disconnected; if the connection response is received within the preset time length, the connection between the terminal and the target AP is successfully established, and the disconnection notice is not required to be generated and output, so that the power consumption of the terminal is saved.
S607, determining to successfully establish connection with the target AP;
s608, generating a disconnection notice, and outputting the disconnection notice to notify a user of the terminal that the terminal is disconnected from the current service AP.
It should be noted that the manner in which the terminal outputs the disconnection notification is not limited here, for example, the terminal may broadcast the disconnection notification by voice, and as shown in fig. 4, the terminal may further display a disconnection notification 401 on a current interface 40 of the terminal to notify a user of the terminal that the terminal is disconnected from the current service AP. It is understood that the current serving AP is an AP that is currently providing a connection service for the terminal.
In a complex environment, especially in an ESS network, due to interference or other reasons, an STA is easily sent an AP Deauth packet, so that a connection between the STA and a current serving AP is released. In a conventional scheme, an STA uploads a Deauth packet to a Kernel (Kernel), and the Kernel transmits the Deauth packet to a framework layer (i.e., an FWK layer) of the STA through a WiFi connection program (i.e., wpa _ notice), so that the STA presents a disconnection behavior (i.e., outputs a disconnection notification) on a User Interface (UI), which causes a problem that the STA immediately presents the disconnection behavior on the UI after receiving the Deauth packet, thereby consuming power consumption of the STA and making a User sense bad.
If the STA receives the Deauth packet, a WIFI driver layer (i.e., a WIFI driver layer) of the STA directly connects to a suitable target AP according to the previous connection record, so that the automatic connection recovery function can be completed. However, the key to the problem here is how to select a suitable target AP so that the connection link between the STA and the target AP is stable after the STA connects to the target AP.
Based on this, in the embodiment of the application, the WIFI driver layer of the STA does not directly upload the AP Deauth packet to the upper layer after receiving the AP Deauth packet, but searches for a suitable target AP in the WIFI driver layer and automatically initiates reconnection to complete the function of automatically recovering the connection. For example, after receiving the AP Deauth packet, the STA does not immediately send a disconnection notification to the kernel, but selects a suitable target AP from the AP scan list (i.e., the candidate AP set) according to a relevant condition to connect, and starts a timer at the same time; before the timer reaches the preset time length, if the STA successfully establishes connection with the target AP, the timer is cancelled; otherwise, if the STA still does not find a suitable target AP when the timer reaches the preset time length, or the STA fails to establish a connection with the target AP, reporting a disconnection notification to an upper layer.
It should be noted that, in other embodiments, a suitable target AP is selected from the AP scan list according to a relevant condition, a scoring mechanism may be generally adopted, and reference may be mainly made to whether the AP in the AP scan list is a 5G channel, RSSI, a transmission success rate of previously transmitted and received data (i.e., the first power generation rate in the above embodiment), a selection speed (i.e., the data transmission rate of the candidate AP in the above embodiment), and a connection success rate of the previous 3 times (i.e., the second power generation rate in the above embodiment); in the score values of the connection parameters, the score value of 5G > the score value of RSSI > the score value of transmission success rate, and the score value of speed > the score value of connection success rate is selected.
Based on the foregoing embodiments, the present application provides an apparatus for reconnecting an AP, where the apparatus includes modules included in the apparatus and units included in the modules, and the modules may be implemented by a processor in a terminal; of course, the implementation can also be realized through a specific logic circuit; in implementation, the processor may be a Central Processing Unit (CPU), a Microprocessor (MPU), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), or the like.
