[0023] Mesh protocol stipulates that when the parameter synchronization conditions are met, the multi-AP controller will package all its current WiFi configuration data in a mesh message (ie: Mesh protocol M2 message) and send it to the multi-AP agent. After the multi-AP agent obtains the WiFi configuration data of the multi-AP controller, it will configure the WiFi configuration data of the multi-AP controller to itself. Among them, the parameter synchronization conditions can be connected to a new AP device, the old device that has been connected is restarted, the connection mode changes, or the multi-AP controller changes.

[0024] In the process of implementing this application, the following problems were found:

[0025] There are differences in the upper limit of the number of WiFi configurations in each AP device. When the upper limit of the number of WiFi configurations in the multi-AP proxy is less than the number of WiFi configured by the multi-AP controller, the multi-AP proxy will randomly discard part of the WiFi configuration in the multi-AP controller during the synchronization of WiFi configuration data, so the part of the WiFi configuration cannot be synchronized to the multi-AP proxy.

[0026] Among them, there are three different situations of abandoned WiFi:

[0027] (1) When the discarded WiFi configuration is frequently used WiFi configuration data, the multi-AP proxy does not have the WiFi configuration data, so the terminal device cannot roam from the multi-AP controller to the multi-AP proxy to continue to access the Internet, that is, the use of seamless roaming function in the network is affected.

[0028] (2) When the discarded WiFi configuration is the configuration data of the backhaul WiFi, at this time, because the multi-AP proxy does not return WiFi information, when the multi-AP proxy wired connection is disconnected, the multi-AP proxy cannot be wirelessly networked through the backhaul WiFi, thereby being unable to achieve the function of self-repair and mixed use of wired and wireless networking, and the terminal device connected to the multi-AP proxy cannot continue to use the WiFi network.

[0029] (3) If the discarded WiFi configuration is an uncommon WiFi configuration (such as guest WiFi), the Mesh networking function will not be affected, and the Internet access and roaming functions of the commonly used WiFi will not be affected.

[0030] In addition, there is no channel for sorting and statistically analyzing the networking status and networking configuration synchronization information between the current two AP devices. Therefore, when an AP device fails, the operation and maintenance personnel cannot quickly locate the problem through the WiFi configuration data of each AP device in the Multi-AP network. They need to arrive at the site for on-site inspection and judgment, which consumes a large labor cost and has low troubleshooting efficiency.

[0031] Based on the above analysis, the present application provides the following solutions, including:

[0032] Figure 1 The present invention provides a flowchart of a method for synchronizing WiFi configuration in a Mesh network. Figure 1 As shown, the method is applied to a multi-AP proxy of a FTTR network, and the method comprises:

[0033] Step 101, obtain the notification information of the multi-AP controller, wherein the notification information is used in the multi-AP proxy WiFi configuration limit value is less than the number of multi-AP controller has been configured WiFi, indicating the multi-AP proxy backhaul WiFi configuration operation;

[0034] Among them, the WiFi configuration data of the multi-AP controller records the configuration data of the WiFi that has been configured by the multi-AP controller.

[0035] Among them, the WiFi configuration data of the multi-AP controller can be transmitted through an AP automatic configuration (auto configuration) WSC (Wi-Fi Simple Configuration, Wi-Fi Simple Configuration) message, which can also be called an M2 message.

[0036] According to the instructions received, you can trigger the multi-AP proxy backhaul WiFi configuration, for the multi-AP proxy to achieve self-healing and wired wireless networking mixed use function to provide support.

[0037] Further, the notification information is located in the WiFi configuration data of the multi-AP controller, that is, used to indicate the configuration of the backhaul WiFi using the WiFi configuration data.

[0038] Furthermore, the notification information is also used to indicate which WiFi among the WiFi configured in the multi-AP controller is the backhaul WiFi.

[0039] Since the number of WiFis configured by the multi-AP controller can be at least two, a flag bit can be configured for each WiFi, and different values ​​of the flag bit are used to indicate whether the WiFi is a backhaul WiFi. For example, 1 bit is allocated to each WiFi; when the value of the bit is 0, it indicates that the WiFi is not a backhaul WiFi; when the value of the bit is 1, it indicates that the WiFi is a backhaul WiFi.

[0040] Step 102: Synchronize the WiFi configuration according to the notification information;

[0041] Specifically, since the multi-AP agent receives the notification information, the multi-AP agent will obtain the multi-AP controller WiFi configuration data in the backhaul WiFi configuration data, and backhaul WiFi configuration operation. Since the multi-AP agent backhaul WiFi configuration, for the later multi-AP agent self-repair and wired wireless networking mixed use function provides support.

[0042] Among them, when each WiFi is configured with a flag bit in the WiFi configuration data of the multi-AP controller, the backhaul WiFi can be determined according to the value of the flag bit.

[0043] The method provided in the embodiment of the present application, the upper limit of the number of multi-AP proxy WiFi configuration is less than the number of multi-AP controller has been configured WiFi, according to the notification information backhaul WiFi configuration operation, to ensure that the multi-AP proxy configuration after executing WiFi configuration synchronization backhaul WiFi, to avoid the occurrence of multi-AP proxy is not configured backhaul WiFi events, for multi-AP proxy can achieve self-repair and wired wireless networking mixed use function to provide support.

[0044] The method provided in the embodiment of the present application is further described below:

[0045] After receiving the WiFi configuration data, the multi-AP proxy can also synchronize the configuration data of other WiFi (i.e., WiFi used to provide wireless communication services for terminal devices) in the WiFi configuration data except the backhaul WiFi. For the synchronization operation of the configuration data of other WiFi, the present application provides the following technical solutions, including:

[0046] Obtain the total number of other WiFis except the backhaul WiFi in the WiFi configuration data of the multi-AP controller to obtain the number to be synchronized;

[0047] When the number to be synchronized is less than or equal to the maximum value of the number of newly added WiFi currently allowed by the multi-AP proxy, a synchronization operation of the WiFi configuration is performed on each WiFi in the other WiFi;

[0048] When the number to be synchronized is less than the maximum number of newly added WiFi currently allowed by the multi-AP proxy and is greater than the number of WiFi currently configured by the multi-AP proxy, select WiFi that meets the preset frequently used conditions from the other WiFi to obtain commonly used WiFi, and perform WiFi synchronization operations including commonly used WiFi configurations.

[0049] Among them, the maximum value of the number of newly added WiFi AP proxy currently allowed is the difference between the upper limit of the number of WiFi configurations in the multi-AP proxy and the total number of WiFi AP proxy currently configured.

[0050] When the number to be synchronized is less than or equal to the maximum number of multi-AP proxy currently allowed to add WiFi, multi-AP proxy can synchronize WiFi configuration data in addition to the other WiFi backhaul WiFi operations, therefore, multi-AP proxy has a common multi-AP controller WiFi, to ensure that the terminal device can roam from the multi-AP controller to the multi-AP proxy to access the Internet.

[0051] When the number to be synchronized is less than or equal to the maximum number of multi-AP proxy currently allowed to add WiFi, multi-AP proxy can only synchronize some WiFi, there is a probability of losing commonly used WiFi, therefore, select commonly used WiFi from WiFi configuration data, and synchronize WiFi configuration including commonly used WiFi, so multi-AP proxy has a commonly used WiFi of multi-AP controller, ensuring that terminal devices can roam from multi-AP controller to the multi-AP proxy to access the Internet.

[0052] Based on the above description, when the multi-AP proxy synchronizes the configuration data of other WiFi except the backhaul WiFi, priority is given to synchronize the commonly used WiFi configuration to ensure that the multi-AP proxy has a multi-AP controller with commonly used WiFi, to ensure that the terminal device can roam from the multi-AP controller to the multi-AP proxy to access the Internet, and can provide seamless roaming function for the terminal device.

[0053] Further, the WiFi configuration data of the multi-AP controller includes a wireless index field corresponding to each WiFi in the multi-AP controller, wherein each wireless index field includes a backhaul WiFi flag, the number of currently configured WiFi and the WiFi number; wherein:

[0054] The backhaul WiFi flag is used to mark whether the corresponding WiFi is the backhaul WiFi;

[0055] The number of currently configured WiFi is used to record the number of WiFi currently configured by the multi-AP controller;

[0056] WiFi number, used to sort each WiFi in the currently configured WiFi number, where the WiFi numbers from small to large correspond to the WiFi commonly used in the multi-AP controller, the multi-AP controller in an uncommon WiFi and the multi-AP controller currently configured backhaul WiFi;

[0057] In the process of performing the synchronization operation of the WiFi configuration, after the return WiFi is determined, the WiFi configuration data is synchronized in the order of WiFi numbers from low to high.

[0058] Figure 2 A schematic diagram of a wireless index field provided in an embodiment of the present application. Figure 2 As shown, the backhaul WiFi flag uses 2 bits, and the bit value is 0, indicating that it is not a backhaul WiFi; the bit value is 1, indicating that it is a backhaul WiFi. The number of currently configured WiFis occupies 3 bits, and 0-7 respectively indicate that the current number of wireless networks of the device is 1-8. The WiFi number occupies 3 bits, where if the WiFi is a commonly used WiFi, the index number of the WiFi is in front; otherwise, the index number of the WiFi is in the back. Therefore, when multiple AP proxies perform the synchronization operation of WiFi configuration, the WiFi configuration data is synchronized in the order of WiFi numbers from low to high, thereby ensuring the synchronization of the configuration data of commonly used WiFi.

[0059] Among them, in the following text, the letter r is used to represent the backhaul WiFi flag, the letter j represents the WiFi number, which is used to sort the number of currently configured WiFi in each WiFi, where the M1 message issued by the multi-AP agent uses the letter m to represent the number of currently configured WiFi, and the M2 message issued by the multi-AP controller uses the letter k to represent the number of currently configured WiFi.

[0060] Optionally, the WiFi configuration data carrying the wireless index field of the multi-AP proxy WiFi is sent, so that the multi-AP controller sends the WiFi configuration data carrying the wireless index field of the multi-AP controller WiFi;

[0061] Among them, the multi-AP agent can transmit its own WiFi configuration data through the AP automatic configuration (auto configuration) WSC message, which can also be called an M1 message.

[0062] Multi-AP proxy by sending WiFi configuration data carrying a wireless index field, to the multi-AP controller that local support for the ability to parse the wireless index field. Therefore, the multi-AP controller can send WiFi configuration data carrying a wireless index field to the multi-AP proxy, so that the multi-AP proxy according to the wireless index field WiFi configuration data synchronization operation.

[0063] Among them, the multi-AP proxy WiFi wireless index field WiFi number from small to large in turn corresponding to the WiFi, followed by the multi-AP controller shared WiFi, the multi-AP proxy unique WiFi and the multi-AP proxy currently configured backhaul WiFi.

[0064] In the above manner, the WiFi shared with the multi-AP controller is set in the front position of the WiFi configuration data, as a common WiFi, can ensure that the terminal device can roam from the multi-AP controller to the multi-AP proxy to access the Internet, can provide seamless roaming function for the terminal device.

[0065] Figure 3 A flowchart of another method for synchronizing WiFi configuration in a Mesh network provided in an embodiment of the present application. Figure 3 As shown, the method is applied to a multi-AP controller in a FTTR network, and the method includes:

[0066] Step 301, obtain the test result, wherein the test result is whether the upper limit of the number of WiFi configurations in the multi-AP proxy is less than the number of WiFis configured by the multi-AP controller;

[0067] Among them, the detection result can be received from the input port; or, according to the preset capability list query to obtain, wherein the capability list records the upper limit value of the number of WiFi configurations in each multi-AP proxy.

[0068] In addition, the multi-AP controller can also be based on the AP basic capabilities (AP radiobasic capabilities) field in the AP M1 message sent by the multi-AP agent in the Maximum BSS support obtained in the upper limit of the number of multi-AP agent WiFi configuration, and then compared with the number of WiFi configured by itself, to obtain the above test results, wherein Maximum BSSsupport indicates the maximum basic service set (Basic Service Set, BSS) that the AP can support. Number.

[0069] Step 302, when the detection result is that the upper limit of the number of multi-AP proxy WiFi configuration is less than the number of multi-AP controller has been configured WiFi, notify the multi-AP proxy backhaul WiFi configuration operation;

[0070] By sending notification information to multiple APs, you can trigger multiple AP agents to backhaul WiFi configuration, providing support for multiple AP agents to achieve self-healing and mixed use of wired and wireless networking.

[0071] The notification information may be sent together with the WiFi configuration data of the multi-AP controller.

[0072] The method of the present application embodiment provides, in the multi-AP proxy WiFi configuration limit value is less than the number of multi-AP controller has been configured WiFi, by transmitting notification information so that the multi-AP proxy backhaul WiFi configuration operation, to ensure that the multi-AP proxy configuration after executing WiFi configuration synchronization with the backhaul WiFi, to avoid the occurrence of multi-AP proxy is not configured backhaul WiFi events, for multi-AP proxy can achieve self-repair and wired wireless networking mixed use function to provide support.

[0073] In addition, since the multi-AP controller needs to synchronize with each multi-AP proxy WIFI configuration operation, the multi-AP controller can be used to record and maintain WIFI information.

[0074] Specifically, obtain the multi-AP proxy WiFi configuration data, and according to the multi-AP proxy WiFi configuration data, update the WiFi information operation and maintenance table.

[0075] Among them, the operation and maintenance table may include the following information: role (multi-AP controller or multi-AP proxy), model, capability value, and WiFi name of each WiFi, WiFi number, and whether it is backhaul WiFi, etc. The model is the product model of the AP device, and the device capability value is the upper limit of the number of WiFi configurations in the AP device.

[0076] The operation and maintenance personnel can use the WiFi name, WiFi number and whether it is the backhaul WiFi of any WiFi in the operation and maintenance table to determine whether the WiFi configuration synchronization is correct (or in line with expectations), and use it to locate and solve possible network failures. The model and capability value of the device can help the operation and maintenance personnel understand the wireless capabilities of different AP devices, and recommend routers that are more suitable for their actual usage scenarios to users, reducing possible failures during use.

[0077] Take a certain application scenario as an example, in which the Mesh network has 4 AP devices. After the Mesh network elects a multi-AP controller, the multi-AP controller records its own information in the operation and maintenance table. Among them, Table 1 records the operation and maintenance information of the multi-AP controller.

[0078]

[0079] Table 1

[0080] The synchronization process of WiFi configuration in the above application scenario is as follows:

[0081] Step A1, each multi-AP proxy sends a M1 message to the multi-AP controller, where the MI message carries multi-AP proxy WiFi configuration data and multi-AP proxy wireless index field;

[0082] Among them, the AP radio basic capabilities field in the M1 message carries the Maximum BSSsupport will inform the upper limit of the number of WiFi configurations in the multi-AP controller n, where the multi-AP agent currently configured WiFi number m meets the following conditions, ie, m ≤ n, where m and n are positive integers.

[0083] Step A2, after receiving the multi-AP controller M1 message, reply M2 message to the multi-AP proxy; wherein the M2 message carries the multi-AP controller WiFi configuration data and multi-AP controller wireless index field;

[0084] Among them, the number of WiFi currently configured by the multi-AP controller is k, where k is a positive integer;

[0085] according to Figure 2 The data format shown in Table 1 has three multi-AP controller WiFi in the M1 message wireless index field is assigned 00010000-00010001-01010002 (ie, 020-021-122), the three wireless index field values ​​can accurately represent the wireless attributes and WiFi number, convenient for multi-AP proxy synchronization operation.

[0086] Step A3, when receiving the M2 message, the multi-AP proxy according to the M2 message carries the WiFi configuration data and the wireless index field of the multi-AP controller, the multi-AP controller WiFi synchronization to the local, so that the wireless terminal device in the Mesh networking of multiple APs in the middle of seamless roaming;

[0087] The synchronization process is performed in the order of the WiFi numbers in the wireless index field from small to large.

[0088] Specifically, when there is a backhaul WiFi with a value of r of 1 in the WiFi configuration data, k in the wireless index field segment is obtained and compared with its own m and n values ​​to confirm the synchronization mode of the backhaul WiFi, including:

[0089] When m≤k≤n, due to k≤n, multi-AP proxy can multi-AP controller all WiFi Z are synchronized to their own equipment, therefore, multi-AP proxy only need to follow the WiFi number from small to large, sequentially synchronize WiFi information to achieve the backhaul WiFi configuration, the final multi-AP proxy synchronization is completed after the number of WiFi and multi-AP controller WiFi the same number, are k.

[0090] When m≤n≤k, due to n≤k, the multi-AP proxy can not synchronize all WiFi of the multi-AP controller to its own device, and the multi-AP proxy can only configure n WiFi at most. Therefore, the multi-AP proxy synchronizes WiFi information in order from small to large according to the value of the WiFi number. When synchronizing the nth WiFi in the multi-AP controller, the value of r in the unsynchronized WiFi clue field of the multi-AP controller is used to determine whether it is the backhaul WiFi, and the WiFi with a value of 1 as the nth WiFi is synchronized, and the configuration data of the WiFi with a value of 0 is discarded. Finally, the number of WiFi after the multi-AP proxy synchronization is completed is n.

[0091] When k≤m≤n, due to k≤m, the number of WiFi currently configured by the multi-AP proxy is greater than or equal to the number of WiFi configured by the multi-AP controller, so the multi-AP proxy only needs to synchronize WiFi information in order from small to large according to the value of the WiFi number. The final first k WiFi information is the same as the multi-AP controller, and the remaining mk WiFi is unique to the multi-AP proxy.

[0092] Through the above process, it is ensured that the multi-AP controller's backhaul WiFi can be synchronized to each multi-AP proxy, and it can also ensure that the commonly used WiFi can be synchronized to each multi-AP proxy, overcoming the problem of no synchronization backhaul WiFi or no synchronization of frequently used WiFi in the prior art.

[0093] Step A4, the multi-AP proxy sends a M1 message to the multi-AP controller, wherein the MI message carries the multi-AP proxy current A WiFi configuration data and multi-AP proxy wireless index field.

[0094] Step A5, the multi-AP controller receives the M1 message, according to the multi-AP proxy WiFi configuration data and multi-AP proxy wireless index field to obtain multi-AP proxy WiFi information, update the operation and maintenance table. For operator operation and maintenance use, see specifically

[0095] Table 2.

[0098] As can be seen from Table 2, the solution provided in the embodiment of the present application can ensure that the return WiFi of the multi-AP controller (WiFi with the WiFi name of 333 in Table 2) can be synchronized to each multi-AP proxy, and can also ensure that the commonly used Wif (WiFi with the WiFi name of 111 in Table 2) can be synchronized to each multi-AP proxy, overcoming the problem of no synchronization of the return WiFi or no synchronization of the frequently used WiFi in the prior art.
