The network selection method of the ACAP networking provided in the embodiment of the present application can be applied to terminals of various communication systems, such as: third-generation mobile communication (3-Generation, 3G) system, fourth-generation mobile communication (4-Generation, 4G) system, fifth-generation mobile communication (5th Generation, 5G) system or subsequent evolved communication system.

[0048] Some terms used in the embodiments of the present application are explained below.

[0049] AP: wireless access point.

[0050] ACAP: The full name is Access Controller + Access Point networking, a wireless local area network (WLAN) architecture based on centralized management.

[0051] SSID: Service Set Identifier, which indicates each subnetwork in a wireless LAN that requires independent authentication.

[0052] RSSI: received signal strength.

[0053] ARP: Address Resolution Protocol.

[0054] Figure 1 is a schematic diagram of an application scenario provided by an exemplary embodiment of the present application. Figure 1 , the application scenario at least includes a terminal, AP1, AP2 and a gateway server. Among them, the terminal, AP1, AP2 and the gateway server communicate through ACAP networking. Specifically, AP1 and AP2 can use the same frequency band, such as the 5G frequency band. In addition, AP1 and AP2 can be configured with the same SSID and Password. When AP1 and AP2 are powered on to provide services in the same time period, the terminal can be associated with AP1 or AP2 through the steps of the ACAP networking method provided in this application.

[0055] Figure 21 is a flow chart of a network selection method for ACAP networking provided by an exemplary embodiment of the present application. The execution subject of the flow chart may be a terminal, for example Figure 1 The terminal shown. The method may include the following steps:

[0056] S201: Detect AP parameters of candidate APs in the ACAP network.

[0057] The candidate AP refers to any one or more APs in the current network that can be selected by the terminal, such as AP1 and AP2. Taking AP1 as an example, when the terminal selects a network, the terminal can detect the AP parameters of the first AP to determine whether the candidate AP is in the preset abnormal AP list.

[0058] In some embodiments, the AP parameters include: an IP address or a MAC address of the candidate AP.

[0059] For example, the terminal may detect the MAC address of the first AP, and thereby determine whether the first AP is in the abnormal AP list according to the MAC address.

[0060] S202: Determine whether the candidate AP is in a preset abnormal AP list according to the AP parameters.

[0061] The abnormal AP list is updated by polling or real-time update, and is used to record the IP addresses or MAC addresses of APs that have serious abnormalities in the network (for example, IP cannot be allocated or the connection is disconnected for a long time).

[0062] S203: If the candidate AP is in the abnormal AP list, the service score of the candidate AP is modified according to a preset score reduction rule to obtain a modified target score, and whether the candidate AP meets the AP association condition of the terminal is determined according to the target score.

[0063] Specifically, when the terminal selects a network, the terminal first obtains the service score of the candidate AP. The service score can be estimated based on factors such as the signal, bandwidth, encryption status, etc. of the candidate AP. This application does not limit the score calculation method.

[0064] For example, the terminal first obtains the service score of the first AP, and then processes the service score according to the preset deduction rule. The purpose of the deduction rule is to reduce the possibility of the terminal selecting the first AP when the first AP has a serious abnormality (for example, unable to allocate an IP or disconnected for a long time), so that the terminal can select a suitable AP as much as possible to ensure the service quality of the network.

[0065] In some embodiments, modifying the service score of the candidate AP according to a preset deduction rule includes the following steps:

[0066] Subtract a preset adjustment value from the service score of the candidate AP, and determine whether the service score after subtracting the adjustment value is greater than the preset minimum value; if the service score after subtracting the adjustment value is greater than the preset minimum value, the target score is the service score after subtracting the adjustment value. If the service score after subtracting the adjustment value is not greater than the preset minimum value, the target score is set to the default value.

[0067] For example, the terminal subtracts a preset adjustment value from the service score of the first AP, and the adjustment value may be 200. It is understandable that the adjustment value may also be flexibly adjusted according to actual conditions, and there is no restriction on this. Further, it is determined whether the service score after subtracting 200 is greater than the preset minimum value. If the service score after subtracting 200 is still greater than the minimum value, the target score is set to the service score after subtracting 200. Conversely, if the service score after subtracting 200 is not greater than the minimum value, the target score is set to the default value. Among them, the minimum value can usually be set to 0, and the default value can be a positive number slightly greater than 0, so that even after the score is reduced, the first AP can still be selected by the terminal, which helps to solve the problem of the terminal having no AP to use in certain network environments.

[0068] In some embodiments, the AP association condition includes any one of the following: there is no other AP in the subnet corresponding to the candidate AP; the target score is the maximum value of the service scores of all APs corresponding to the subnet.

[0069] For example, if the second AP is not powered on and there are no other APs available in the subnet corresponding to the first AP, the first AP satisfies the AP association condition. For another example, if the target score of the first AP is greater than the current service score of the second AP, the target score is the maximum value of the service scores of all APs corresponding to the subnet, then the first AP satisfies the AP association condition.

[0070] If the candidate AP is not in the abnormal AP list, it is directly determined whether the candidate AP meets the AP association condition according to the service score of the candidate AP.

[0071] S204: If the candidate AP meets the AP association condition of the terminal, the terminal is enabled to access the candidate AP.

[0072] When the first AP meets the AP association condition, the terminal accesses the first AP. It can be seen that based on the above steps, when there are multiple APs to choose from in the same SSID, the terminal can avoid abnormal APs as much as possible, and when there is only one AP in the same SSID, the terminal can associate with the AP, thereby solving the problem of the terminal having no AP to use in certain network environments, avoiding signal blind spots, and improving the user experience.

[0073] If the candidate AP does not meet the terminal's AP association conditions, no processing is performed.

[0074] Furthermore, in some embodiments, after the terminal is enabled to access the candidate AP, the method further includes:

[0075] Polling detection of received signal strength RSSI;

[0076] When the polling times meet the preset triggering condition, an Address Resolution Protocol ARP request message is sent to the candidate AP to detect the reachability of the candidate AP.

[0077] Specifically, the terminal may send an Address Resolution Protocol ARP request message to a candidate AP (ie, a neighbor AP) by polling RSSI, thereby triggering a reachability detection to the candidate AP.

[0078] Preferably, in each polling detection process, the following steps are further performed:

[0079] Get the network interface information of the terminal;

[0080] Determine whether the terminal successfully receives the packet within the preset detection time according to the network interface information;

[0081] If the terminal fails to successfully receive the packet within the detection time, it immediately sends an ARP request message to the candidate AP to detect the reachability of the candidate AP.

[0082] The purpose of the above steps is to use the RSSI polling time to detect whether the candidate AP has the risk of not forwarding data. If the candidate AP does not forward data within the detection time, it means that the terminal is likely to be unable to access the network, and the reachability detection is immediately triggered.

[0083] In some embodiments, after sending the ARP request message to the candidate AP, the method further includes:

[0084] Obtain the reachability test results of the candidate APs;

[0085] Determine whether the terminal needs to roam or reconnect based on the reachability test result;

[0086] If the terminal does not need to roam or reconnect, it continues to detect the RSSI of the candidate AP.

[0087] Figure 3 FIG. 1 is a logic diagram of an example of accelerating reachability detection provided by an exemplary embodiment of the present application. Figure 3 , an example of speeding up reachability detection is as follows:

[0088] S301, polling to detect RSSI;

[0089] S302, determine whether the polling times meet the trigger condition, if yes, execute step S303, otherwise, execute step S301;

[0090] An example of a trigger condition is as follows:

[0091] RxSuccessCheckCount++>=3.

[0092] S303, determining whether the terminal successfully receives the packet within the detection time, if so, executing step S301, otherwise, executing step S304;

[0093] S304, determine whether the backup AP is reachable; if so, execute step S301, otherwise, execute step S305;

[0094] S305, roaming or reconnecting to the network.

[0095] Based on the above method, after the terminal selects the network, this application can also detect whether the alternative AP has the risk of not forwarding data by using the RSSI polling time, thereby speeding up the triggering logic of reachability detection, shortening the time that the terminal cannot access the network, and improving the user experience.

[0096] In order to better illustrate the technical effect of the present application, a test example of the ACAP network selection method is given. The scenario of the test example is roughly as follows Figure 1 As shown in the figure, the total duration is 4.5 hours. By controlling the power on and off time of AP1 and AP2 and the packet loss time, the power off anomaly and denial of service anomaly that may occur in AP1 and AP2 in actual scenarios are simulated.

[0097] The control behavior for AP1 specifically includes: first powering on AP1, setting a timer of 5 minutes, powering on AP2 at the 3rd minute of the countdown, randomly causing AP1 to drop packets to the terminal during the coexistence time of the Wi-Fi signals of AP1 and AP2, and preventing AP1 from dropping packets after the coexistence time.

[0098] The control behavior for AP2 specifically includes: first powering on AP2, setting a timer of 5 minutes, powering on AP1 at the 3rd minute of the countdown, randomly causing AP2 to drop packets to the terminal during the coexistence time of the Wi-Fi signals of AP1 and AP2, and preventing AP2 from dropping packets after the coexistence time.

[0099] Then, a cyclic test is performed based on the above control behavior.

[0100] Figure 4 is a result diagram of a test example provided by an exemplary embodiment of the present application. Figure 4, the horizontal axis is the timestamp, and the vertical axis is the average ping time. In the entire test example, the terminal's ping data packet loss rate was measured to be 9%, the average ping time was 33ms, and the probability of switching to a normal AP in the test was 76.4%. Compared with the existing technology, the terminal's packet loss rate is reduced and it is more likely to switch to a normal AP, which solves the problem of the terminal having no AP to use in certain network environments and avoids signal blind spots.
