Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method, device and storage medium for enabling WLAN extended fields to take effect in real time. Background Technology

[0002] WiFi (Wireless Fidelity) networking is a wireless local area network (WLAN) networking technology based on the IEEE 802.11 standard.

[0003] In WiFi networking, the relationship between the Access Controller (AC) and the Access Point (AP) is the core of centralized wireless network management. The AC is used to centrally manage and control multiple APs and the entire wireless LAN, while the APs provide wireless signal coverage, enabling terminals to connect to the wireless network.

[0004] Currently, the AC's management and control of APs is mainly based on the fields supported in the CAPWAP (Control And Provisioning of Wireless Access Points Protocol Specification) protocol: the AC sends the fields supported in the CAPWAP protocol to the AP through the IEEE 802.11 WLAN Configuration Request message, thereby realizing the function of AP management.

[0005] To adapt to changing application scenarios, technicians often configure extended fields in the CAPWAP protocol to achieve functional expansion and personalized configuration. However, the CAPWAP protocol may not support the configured extended fields, causing the extended fields to fail to take effect. Currently, there is no method to make the extended fields of the protocol in the wireless LAN take effect in real time. Summary of the Invention

The method includes: establishing a communication tunnel with a wireless access point; appending a preset field not supported by the communication protocol to the service set identifier to obtain a configuration request message; and sending the configuration request message to the wireless access point through the communication tunnel via an update WLAN command.

[0008] According to a method for enabling real-time activation of WLAN extended fields provided by the present invention, a configuration request message is obtained by appending a preset field not supported by the communication protocol to the service set identifier.

The method includes: establishing a communication tunnel with an access controller; receiving an update WLAN command sent by the access controller through the communication tunnel, wherein the update WLAN command includes a configuration request message; appending a preset field not supported by the communication protocol to the service set identifier of the configuration request message; parsing the preset field in the configuration request message and enabling the preset field to activate in real time.

[0011] According to a method for implementing real-time activation of WLAN extension fields provided by the present invention, the configuration request message is generated based on the target service set identifier and IEEE 802.11 wireless LAN. The target service identifier includes the service set identifier and a preset field not supported by the communication protocol appended to the field of the service set identifier.

[0012] According to the present invention, a method for enabling real-time activation of WLAN extended fields is provided, wherein the communication tunnel is a CAPWAP tunnel and the communication protocol is the CAPWAP protocol.

[0013] The present invention also provides an access controller, comprising: a communication establishment module for establishing a communication tunnel with a wireless access point; a configuration module for appending a preset field not supported in the communication protocol to a service set identifier to obtain a configuration request message; and a distribution module for distributing the configuration request message to the wireless access point through the communication tunnel via an update WLAN command.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0026] Please see Figure 1 , Figure 1 This is one of the flowcharts illustrating the method for implementing real-time activation of WLAN extension fields provided by the present invention. In this embodiment, the method for implementing real-time activation of WLAN extension fields is applied to an access controller and includes steps S110 to S130, each step of which is as follows:

[0027] S110: Establishes a communication tunnel with the wireless access point.

[0028] In WiFi networking, the access controller (AC) needs to manage and control the wireless access points (APs) through fields in the communication protocol.

[0029] Specifically, the fields in the communication protocol describe specific management and control information. The configuration message can carry the fields in the communication protocol. The access controller can send the fields in the communication protocol to the wireless access point through the configuration message. After receiving the configuration message, the wireless access point can parse and apply the fields in the configuration message based on the parsing rules negotiated between the access controller and the wireless access point, thereby realizing the access controller's management and control of the wireless access point.

[0030] Generally, if a field in a configuration message is applied by a wireless access point, it indicates that the field in the communication protocol has taken effect.

[0031] Before the access controller sends out configuration messages, it needs to establish a communication tunnel with the wireless access point. The access controller and the wireless access point can exchange data and communicate through the communication tunnel.

[0032] S120: Append the preset fields that are not supported in the communication protocol to the service set identifier to obtain the configuration request message.

[0033] To adapt to changes in application scenarios, technicians often configure extended fields in communication protocols to achieve functional expansion and personalized configuration. However, the CAPWAP communication protocol may not support the configured extended fields, causing the extended fields to fail to take effect.

[0034] Generally, in WiFi networking, the communication protocol includes a Service Set Identifier (SSID) field, which is used to provide network identification and authentication. The SSID field is usually the last valid field in the communication protocol, and its length is variable.

[0035] Because the length of the service set identifier field is variable, information not defined in the original communication protocol, i.e., preset fields not supported by the original communication protocol, can be added to the service set identifier without changing the original communication protocol structure, so as to achieve functional expansion and personalized configuration.

[0036] Since the access controller needs to send fields in the communication protocol to the wireless access point via configuration messages, a new configuration message needs to be generated when the fields in the communication protocol change.

[0037] Specifically, since the configuration message can carry the service set identifier field in the communication protocol, preset fields that are not supported in the communication protocol can be appended to the service set identifier to obtain the configuration request message.

[0038] S130: The configuration request message is sent to the wireless access point through the communication tunnel via the update WLAN command.

[0039] The access controller triggers an Update WLAN command, which sends a configuration request message to the wireless access point through the communication tunnel. This allows the wireless access point to parse and apply the service set identifier field in the configuration message based on the parsing rules pre-negotiated between the access controller and the wireless access point.

[0040] The method for enabling real-time activation of WLAN extended fields provided in this embodiment is applied to an access controller. The method includes: establishing a communication tunnel with a wireless access point; appending a preset field not supported by the communication protocol to the service set identifier to obtain a configuration request message; and sending the configuration request message to the wireless access point through the communication tunnel via an update WLAN command. Because the configuration request message carries preset fields not supported by the communication protocol (i.e., extended fields), after the configuration request message is sent to the wireless access point through the communication tunnel via the update WLAN command, the wireless access point can parse and apply the extended fields based on the configuration request message, thus enabling the extended fields of the protocol in the wireless local area network to take effect in real time.

[0041] In some embodiments, appending a preset field not supported by the communication protocol to the service set identifier to obtain a configuration request message includes: appending a preset field not supported by the communication protocol to the fields of the service set identifier to obtain a target service set identifier; and generating a configuration request message based on the target service set identifier and the IEEE 802.11 wireless LAN.

[0042] Specifically, since the length of the service set identifier field is variable, preset fields that are not supported by the original communication protocol can be appended to the service set identifier without changing the original communication protocol structure. By adding separators, such as @, &, etc., the service set identifier field and the preset fields that are not supported by the original communication protocol can be distinguished, thus obtaining the target service set identifier.

[0043] Furthermore, based on the target service set identifier and the IEEE 802.11 wireless LAN protocol standard, a configuration request message is constructed and generated.

[0044] Please see Figure 2 , Figure 2 This is a signaling diagram illustrating the process of configuration request message interaction between the AC and AP provided by the present invention.

[0045] like Figure 2 As shown, the configuration request message is an IEEE 802.11 WLAN Configuration Request message.

[0046] In some embodiments, the communication tunnel is a CAPWAP tunnel; the communication protocol is the CAPWAP protocol.

[0047] Please see Figure 3 , Figure 3This is the second flowchart illustrating the method for implementing real-time activation of WLAN extension fields provided by the present invention. In this embodiment, the method for implementing real-time activation of WLAN extension fields is applied to a wireless access point, including steps S310 to S330, each step of which is as follows:

[0048] S310: Establishes a communication tunnel with the access controller.

[0049] S320: Receives WLAN update commands sent by the access controller through the communication tunnel.

[0050] The WLAN update command includes a configuration request message; the service set identifier in the configuration request message has a preset field that is not supported by the communication protocol.

[0051] Specifically, after receiving the update WLAN command sent by the access controller, a configuration request message is obtained based on the update WLAN command.

[0052] like Figure 2 As shown, the configuration request message issued by the access controller is an IEEE 802.11 WLAN ConfigurationRequest message.

[0053] After receiving the update WLAN command sent by the access controller, the wireless access point obtains the IEEE 802.11 WLAN Configuration Request message based on the update WLAN command and returns an IEEE 802.11 WLAN Configuration Response message to the access controller so that the access controller knows that the wireless access point has correctly received the configuration request message.

[0054] S330: Parse the preset fields in the configuration request message and make the preset fields take effect in real time.

[0055] In some embodiments, the configuration request message is generated based on the target service set identifier and the IEEE 802.11 wireless LAN. The target service identifier includes a service set identifier and a preset field appended to the field of the service set identifier that is not supported by the communication protocol.

[0056] In some embodiments, the communication tunnel is a CAPWAP tunnel; the communication protocol is the CAPWAP protocol.

Figure 4 , Figure 4 This is a schematic diagram of the access controller provided by the present invention. In this embodiment, the access controller includes a communication establishment module 410, a configuration module 420, and a distribution module 430.

[0059] The configuration module 420 is used to append preset fields that are not supported in the communication protocol to the service set identifier to obtain a configuration request message.

[0060] The distribution module 430 is used to distribute configuration request messages to the wireless access point through the communication tunnel via update WLAN commands.

[0061] In some embodiments, the configuration module 420 is used to append a preset field that is not supported in the communication protocol to the field of the service set identifier to obtain the target service set identifier; and generate a configuration request message based on the target service set identifier and the IEEE 802.11 wireless LAN.

[0064] Establish communication module 510 to establish a communication tunnel with the access controller.

[0065] The receiving module 520 is used to receive update WLAN commands sent by the access controller through the communication tunnel.

[0066] The WLAN update command includes a configuration request message; the service set identifier in the configuration request message has a preset field that is not supported by the communication protocol.

[0067] The parsing module 530 is used to parse the preset fields in the configuration request message and make the preset fields take effect in real time.

[0068] In some embodiments, the configuration request message is generated based on the target service set identifier and the IEEE 802.11 wireless LAN. The target service identifier includes a service set identifier and a preset field appended to the field of the service set identifier that is not supported by the communication protocol.
