Detailed ways

The technical solutions of the present application will be further elaborated below with reference to the accompanying drawings and embodiments.

This embodiment first provides a network architecture. FIG. 1 is a schematic diagram of the composition structure of the network architecture according to the embodiment of the present application. As shown in FIG. 1 , the network architecture includes multiple terminals 11 to 1N, multiple APs 21 to 2M, and a wireless network. 31 , wherein the terminals 11 to 1N connect to the wireless network 31 by establishing a connection with one of the APs 21 to 2M, and realize data interaction with the wireless network 31 . Generally speaking, a terminal can be various types of devices with the ability to reconnect to an AP, for example, the terminal can include a mobile phone, a tablet computer, a desktop computer, a personal digital assistant, a navigator, a digital phone, a video phone, a TV, Sensing devices, etc., may also include personal computers, servers, or network devices. It should be noted that, in the art, the terminal is also called STA.

This embodiment provides a method for reconnecting to an AP. The method is applied to a terminal. The functions implemented by the method can be implemented by calling a program code by a processor in the terminal. Of course, the program code can be stored in a computer storage medium. It can be seen that, The terminal includes at least a processor and a storage medium.

FIG. 2 is a schematic flowchart of the implementation 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 it is determined that the AP needs to be reconnected, obtain the values of at least two connection parameters of each candidate AP in the candidate AP set obtained by scanning; the connection parameters affect the connection between the terminal and the corresponding candidate AP parameters of stability;

For example, if the signal strength (that is, the received signal strength) of the signal received by the terminal from the current serving AP is smaller than the preset strength threshold, it is determined that the AP needs to be reconnected, and the reconnected APs are generally other than the current serving AP. other APs; for another example, if the terminal receives the Deauth packet, it is determined that the AP needs to be reconnected.

Understandably, the parameters affecting the connection stability between the terminal and the corresponding candidate AP generally include at least two of the following: the operating frequency of the candidate AP, the terminal receiving the signal sent by the candidate AP The received signal strength at the time, the first success rate of data transmission between the terminal and the candidate AP, the data transmission speed of the candidate AP, and the second success rate of the terminal connecting to the candidate AP; The received signal strength is the main parameter that affects the connection stability between the terminal and the corresponding AP.

S202, converting the value of each connection parameter of each of the candidate APs into a corresponding score value according to a corresponding conversion rule;

It should be noted that, since different connection parameters have different influences 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 the main factors affecting the connection stability. parameter. Therefore, in practical applications, the conversion rules configured for each connection parameter are generally different, that is, each connection parameter has a corresponding conversion rule.

S203, based on the score value of each connection parameter of each candidate AP, determine a target AP from the candidate AP set;

Understandably, 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 of the candidate APs, and then based on the total score value of each of the candidate APs, from the candidate APs The target AP is determined from the AP set, for example, the candidate AP with the highest total score value is determined as the target AP. In this way, the terminal can obtain better connection link quality only after establishing a connection with the target AP.

S204. Send a connection request to the target AP, where the connection request is used to request to establish a connection with the target AP.

In this embodiment of the present application, a target AP is selected from the candidate AP set based on the score values of multiple connection parameters of each candidate AP, so that the terminal can obtain better results after establishing a connection with the target AP. connection link quality.

This embodiment of the present application provides another method for reconnecting to an AP. The method is applied to a terminal, and the method includes steps S301 to S306:

S301. Preload a score mapping table corresponding to each connection parameter, where the score mapping table is used to record a preset range to which the value of the corresponding connection parameter belongs and a score value corresponding to the preset range;

Since different connection parameters have different influences on the connection stability between the corresponding AP and the terminal, when configuring the corresponding score mapping table for each connection parameter, the configuration range of the score value is different. For example, FIG. 3 is a score mapping table corresponding to each connection parameter in this embodiment of the present application. As shown in FIG. 3 , table 301 is a score mapping table corresponding to the operating frequency, and table 302 is a score mapping table corresponding to the received signal strength Table 303 is a score mapping table corresponding to the first success rate, 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 success rate.

As can be seen from Figure 3, the configuration range of the score value corresponding to the operating frequency is 90-100 points, of which the lowest score of the operating frequency is 90 points; the configuration range of the score value corresponding to the received signal strength is 70-90 points The minimum score of the received signal strength is 70 points; the configuration range of the score value corresponding to the first success rate is 60 points to 70 points, of which the minimum score of the first success rate is 60 points; the corresponding data transmission speed The configuration range of the score value is 50-60 points, of which the lowest score of the data transmission speed is 50 points; the configuration range of the score value corresponding to the second success rate is 40-50 points, of which the lowest score of the second success rate is The score is 40 points; it can be seen that according to the influence degree of each connection parameter on the connection stability between the terminal and the corresponding candidate AP, the corresponding score value range is configured for the corresponding connection parameter, that is, In descending order of influence degree, the minimum score value configured for each connection parameter decreases in turn. In this way, when the score value of each connection parameter is determined through steps S303 and S304, it can be ensured that: the score value of the operating frequency ≥ the score value of the received signal strength ≥ the first success rate The score value ≥ the score value of the data transmission speed ≥ the score value of the second success rate, so that the score value of each connection parameter is more in line with the actual situation.

Of course, in other embodiments, the configuration range of the score value may also be the same. In this way, when step S305 is implemented, that is, based on the score value of each connection parameter of each candidate AP, the When determining the target AP in the set, it is necessary to determine the total score value of the corresponding candidate AP based on the score value of each connection parameter of each candidate AP and the influence factor of the corresponding connection parameter; then, based on the total score of each candidate AP The target AP is determined from the candidate AP set; wherein, the influence factor is used to represent the degree of influence of the corresponding connection parameter on the connection stability between the terminal and the corresponding candidate AP. For example, the impact factors assigned to the working frequency, the received signal strength, the first success rate, the data transmission speed and the second success rate in sequence 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 can be determined first, and then the sum of the products of all connection parameters of the candidate AP can be determined as the corresponding candidate AP total score value.

S302. If it is determined that the AP needs to be reconnected, obtain the values of at least two connection parameters of each candidate AP in the candidate AP set obtained by scanning;

S303, based on the value of each connection parameter of each candidate AP, from the corresponding score mapping table, determine the target range to which the value belongs;

S304, based on the target range, determine the score value of the corresponding connection parameter from the corresponding score mapping table;

For example, the obtained operating frequency of the candidate AP is 5.725 GHz. As shown in FIG. 3 , from the corresponding score mapping table 301 , it can be determined 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 embodiment.

S305, based on the score value of each connection parameter of each candidate AP, determine a target AP from the candidate AP set;

S306. Send a connection request to the target AP, where the connection request is used to request to establish a connection with the target AP.

This embodiment of the present application provides yet another method for reconnecting to an AP, the method is applied to a terminal, and the method includes steps S401 to S405:

S401. If it is determined that the AP needs to be reconnected, obtain the values of at least two connection parameters of each candidate AP in the candidate AP set obtained by scanning; the connection parameters affect the connection between the terminal and the corresponding candidate AP parameters of stability;

S402, converting the value of each connection parameter of each candidate AP into a corresponding score value according to a corresponding conversion rule;

S403, based on the score value of each connection parameter of each candidate AP, determine the total score value of the corresponding candidate AP;

Here, it should be noted that, when configuring the score mapping table corresponding to each connection parameter, if the configuration range of the score value corresponding to each connection parameter is different, directly convert all connection parameters of each candidate AP The sum of the score values is determined as the total score value of the corresponding candidate AP; if the configuration range of the score values corresponding to each connection parameter is the same, the product of the score value of each connection parameter and the corresponding influence factor can be determined first, 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. Based on the total score value of each candidate AP, determine a target AP from the candidate AP set;

Generally speaking, 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 embodiment.

S405. Send a connection request to the target AP, where the connection request is used to request to establish a connection with the target AP.

This embodiment of the present application provides yet another method for reconnecting to an AP. The method is applied to a terminal, and the method includes steps S501 to S511:

S501. Obtain a first number of times of sending, where the first number of times of sending is the number of times that the terminal sends data to the candidate AP within a preset time period;

S502. Obtain a first number of receptions, where the first number of receptions is the number of times the terminal receives data sent by the candidate AP within a preset time period;

S503. Determine the first success rate based on the first number of times of sending and the first number of times of receiving;

It should be noted that the first number of times of sending and the first number of times of receiving are generally interaction information that has been recorded in advance by the terminal. When determining the first success rate, the interaction information can be directly obtained, so as to determine the first success rate. For example, the ratio of the first reception times to the first transmission times may be determined as the first success rate.

S504. Obtain a second number of times of sending, where the second number of times of sending is the number of times the terminal sends a connection request to the candidate AP within a preset time period;

S505. Acquire a second number of times of reception, where the second number of times of reception is the number of times that the terminal receives a connection response sent by the candidate AP within a preset time period;

S506. Determine the second success rate based on the second number of times of sending and the second number of times of receiving;

Similarly, the second sending times and the second receiving times are generally also interaction information that has been recorded in advance by the terminal. When determining the second success rate, the interaction information can be directly obtained, so as to determine the second success rate. For example, the ratio of the second reception times to the second transmission times may be determined as the second success rate.

S507. Save the first success rate and the second success rate;

It should be noted that, in other embodiments, steps S504 to S506 may be performed first, and then steps S501 to S503 may be performed, wherein, when performing steps S504 to S506, the execution order of steps S504 and S505 is not limited; When steps S501 to S503 are executed, the execution order of steps S501 and S502 is also not limited. After steps S501 to S507 are performed, the following steps S508 to S511 do not need to be performed immediately. When the conditions for reconnecting to the AP are satisfied, steps S508 to S511 are started.

S508. If it is determined that the AP needs to be reconnected, obtain the values of multiple connection parameters of each candidate AP in the candidate AP set obtained by scanning; wherein, the connection parameters 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 data transmission speed of the candidate AP, the first success rate and the second success rate;

S509, converting the value of each connection parameter of each candidate AP into a corresponding score value according to a corresponding conversion rule;

S510, based on the score value of each connection parameter of each candidate AP, determine a target AP from the candidate AP set;

S511. Send a connection request to the target AP, where the connection request is used to request to establish a connection with the target AP.

This embodiment of the present application provides another method for reconnecting to an AP, the method is applied to a terminal, and the method includes steps S601 to S608:

S601. If an attack message is received, it is forbidden to generate a disconnection notification, and it is determined that the AP needs to be reconnected. In this case, go to step S602; wherein, the attack message is used to block the connection between the terminal and the current serving AP, so The disconnection notification is used to notify the user of the terminal that the terminal has been disconnected from the current serving AP;

It should be noted that, in practical applications, after receiving the attack message, the program for generating a disconnection notification is not executed, but step S602 is directly executed, that is, at least one of each candidate AP in the candidate AP set obtained by scanning is obtained. The numeric values of the two connection parameters.

Generally speaking, the attack message is frequently sent, especially when the attack message is a Deauth packet, a large number of Deauth packets may cause the terminal to be disconnected frequently. After the packets are packaged, a disconnection notification is generated and displayed on the screen of the terminal, which not only consumes the power of the terminal, but also affects the senses of the user corresponding to the terminal. Therefore, after receiving the attack message, the disconnection notification is temporarily not generated, which not only saves the power consumption of the terminal, but also avoids frequent interference to the user.

S602, acquiring the values of at least two connection parameters of each candidate AP in the set of candidate APs obtained by scanning; the connection parameters are parameters that affect the connection stability between the terminal and the corresponding candidate AP;

S603, converting the value of each connection parameter of each candidate AP into a corresponding score value according to a corresponding conversion rule;

S604, based on the score value of each connection parameter of each candidate AP, determine a target AP from the candidate AP set;

S605. Send a connection request to the target AP, where the connection request is used to request to establish a connection with the target AP;

S606. Determine whether a connection response is received within a preset time period; if yes, perform step S607; otherwise, perform step S608; wherein the connection response is used to inform the terminal that the target AP and the terminal are successfully established connect.

Understandably, if the connection response is not received within the preset time period, it means that the terminal has failed to establish a connection with the target AP. At this time, step S608 is performed, that is, a disconnection notification is generated, and the disconnection notification is output. line notification to notify the user of the terminal that the terminal has been disconnected from the current serving AP; if the connection response is received within a preset time period, it means that the terminal and the target AP have successfully established a connection, In this case, it is unnecessary to generate and output the disconnection notification, thereby saving the power consumption of the terminal.

S607, determine that a connection is successfully established with the target AP;

S608. Generate a disconnection notification, and output the disconnection notification to notify the user of the terminal that the terminal has been disconnected from the current serving 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, as shown in FIG. A disconnection notification 401 is displayed on the interface 40 to inform the user of the terminal that the terminal has been disconnected from the current serving AP. Understandably, the current serving AP is the AP that is currently providing connection services for the terminal.

In a complex environment, especially in an ESS network, due to interference or other reasons, the STA is likely to be sent an AP Deauth packet, so that the connection between the STA and the current serving AP is released. In the traditional solution, the STA will upload the Deauth packet to the kernel (Kernel), and the kernel will then transmit the Deauth packet to the STA's framework layer (ie the FWK layer) through the WiFi connection program (ie wpa_supplicant), so that the STA can be used in the user interface ( The disconnection behavior is displayed on the User Interface (UI) (that is, the disconnection notification is output). The problem caused by this is that the disconnection behavior is displayed on the UI immediately after receiving the Deauth packet, which not only consumes the power consumption of the STA, but also Make the user feel bad.

If the STA receives the Deauth packet, the WIFI driver layer (ie, the 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. But the crux of the problem at this time is how to select a suitable target AP so that the connection link between the STA and the target AP is relatively stable after connecting to the target AP.

Based on this, in the embodiment of the present 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 a reconnection to complete the automatic recovery of the connection. function. 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 (that is, the candidate AP set) according to relevant conditions for connection, and at the same time Start the timer; before the timer reaches the preset duration, if the STA successfully establishes a connection with the target AP, the timer is cancelled at this time; otherwise, if the STA still does not find a suitable target AP when the timer reaches the preset duration, or , the STA fails to establish a connection with the target AP, and reports the disconnection to the upper layer.

It should be noted that, in other embodiments, a suitable target AP is selected in the AP scan list according to relevant conditions, and a scoring mechanism may be adopted as a whole, mainly by referring to whether the AP in the AP scan list is a 5G channel, RSSI, sent before and the transmission success rate of received data (that is, the first success rate described in the above embodiment), the selection speed (that is, the data transmission speed of the candidate AP described in the above embodiment), and the connection success rate of the first three times (that is, the The second success rate described in the above-mentioned embodiment); wherein, on the score value of each connection parameter, the score value of 5G > the score value of RSSI > the score value of the transmission success rate, and the score value of the selected speed Value>The score value of the connection success rate.
