Description

Technical Field

The present disclosure relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for processing configuration information, a computer-readable storage medium, and an electronic device.

Background

Based on security considerations, a WLAN (Wireless Local Area Network) should periodically update Wireless information, such as replacing a password or using a new SSID (Service Set Identifier). In the IoT (Internet of Things) scenario using WLAN, too many WLAN terminals are associated to change the configuration. Generally, in an IoT scenario, there may be tens of WLAN terminals associated with access under the same WLAN SSID. When setting the WLAN access information for the IoT device, since the IoT device usually has no input/output device, and often needs to be modified by a corresponding APP (Application), the individual manufacturer may also need to reset the IoT device.

Currently, a WLAN password or SSID change requires reconfiguration at each terminal. These cumbersome steps may reduce the willingness of the user to update the WLAN wireless information periodically, reducing the security of the WLAN network.

In view of the above, there is a need in the art to develop a new method and apparatus for processing configuration information.

Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the subject matter of the present disclosure can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and the like. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.

The terms "a," "an," "the," and "said" are used in this specification to denote the presence of one or more elements/components/parts/etc.; the terms "comprising" and "having" are intended to be inclusive and mean that there may be additional elements/components/etc. other than the listed elements/components/etc.; the terms "first" and "second", etc. are used merely as labels, and are not limiting on the number of their objects.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities.

There are two methods for updating configuration information of a wireless local area network in the related art. One is to replace the terminal password by NFC (Near Field Communication) contact, and the other is to input the access hotspot without Configuration in WPS (Wi-Fi Protected Setup) and PBC (Push Button Configuration).

First, replacing the password of the terminal through the NFC contact mode may update the password in an offline mode, and the NFC card with new configuration information needs to be updated by contacting the terminal with the NFC function.

The second non-configuration input access hotspot using the WPS and PBC modes may acquire configuration in a WPS plus key mode.

In both of these two modes, after the wireless access point updates the access configuration information, the configuration update operation needs to be performed on the terminal device one by one.

However, the first method of replacing the terminal password by the NFC contact method is to wirelessly send an encrypted password message of an old password, and the response message is encrypted by a new password, which also requires modifying the flow of the 802.11 protocol (802.11 wireless network standard), and thus the security is not sufficient.

The method uses WPS and PBC mode to input Access hotspot without configuration, and transmits the encrypted WiFi password of the connection state terminal MAC (media Access Control Address) and the media Access Control Address, also called local area network Address, Ethernet Address (Ethernet Address) or physical Address, by broadcasting and multicasting modes, and the terminal uses the MAC to decrypt and replace the original WiFi password.

In the second method, since the MAC of the target STA is used for encryption, different data packets need to be sent for each terminal, which increases air interface overhead. And, because the target MAC encryption is adopted, but the transmitted protocol frame has the target MAC, the security is poor.

In order to solve the problems in the related art, the present disclosure provides a method for processing configuration information, which is applied to a wireless access point. Fig. 1 shows a flow chart of a method for processing configuration information, which, as shown in fig. 1, comprises at least the following steps:

step S110, determining the terminal equipment associated with the wireless access point, and acquiring the original configuration information of the terminal equipment.

And S120, when the target configuration information is acquired, starting a new access point at the wireless access point by using the target configuration information.

And S130, updating the original configuration information of the terminal equipment by using the target configuration information so as to enable the terminal equipment to be associated with the new access point.

In the exemplary embodiment of the disclosure, the original configuration information is uniformly and automatically updated by using the target configuration information, so that the complexity of changing the wireless access configuration information by the internet of things device and other terminal devices is reduced, the terminal access process in a household scene and other scenes is facilitated, the frequency of updating the configuration information by the wireless local area network is further improved, the security of the wireless local area network is increased, and the reflux degree of a user is improved to a certain extent.

The following describes each step of the configuration information processing method in detail.

In step S110, a terminal device associated with the wireless access point is determined, and original configuration information of the terminal device is acquired.

In an exemplary embodiment of the present disclosure, a Wireless Access Point (AP) is a typical application of a Wireless local area network. The wireless AP is a bridge for communication between a wireless network and a wired network, and is a core device for establishing a wireless local area network.

The wireless access point mainly provides mutual access between the wireless workstation and the wired local area network. Thus, wireless stations within the signal coverage of the AP can communicate with each other through it, and there is essentially no way for the AP to establish a WLAN that is truly Internet-accessible. The AP in the WLAN corresponds to the role of the transmitting base station in the mobile communication network.

In a wireless network, the AP acts as a hub for a wired network that can connect various wireless clients. The network card used by the wireless client is a wireless network card, and the transmission medium is air (electromagnetic wave).

Logically, the wireless access point is the central point of a wireless unit. All radio signals in the unit have to pass through it for exchange. Although a wireless local area network in a peer-to-peer mode can be formed by using only a wireless network card without using the AP, such a wireless local area network is somewhat special and is only suitable for temporary wireless connection.

After the AP is used, not only can permanent wireless connection service be obtained, but also the users can be managed in a centralized way, and the security of the wireless network is greatly improved.

In general, a wireless AP is a bridge for communication between a wireless network and a wired network. Since the coverage area of the wireless AP is a circular area spreading out, the wireless AP should be placed at the center of the wireless network as much as possible, and the linear distance between each wireless client and the wireless AP should preferably not exceed 30m, so as to avoid communication failure due to excessive attenuation of communication signals.

The WLAN mainly includes Stations (STAs), access points, a wireless medium, and a Distribution System (DS). The STA in the WLAN is generally a client, and may be a computer equipped with a wireless network card, or a smart phone with a WiFi module, and the like, which is not limited in this exemplary embodiment. The STA may be mobile or fixed, and is the most basic component of the wireless lan.

Therefore, the terminal device associated with the wireless access point is the terminal device in the wireless local area network.

After determining the terminal device associated with the wireless access point, a corresponding terminal list may be generated according to a state of whether the terminal device is online.

In an alternative embodiment, fig. 2 shows a flowchart of a method for generating a terminal list, and as shown in fig. 2, the method at least includes the following steps: in step S210, when the terminal device associated with the wireless access point is in an online state, an online terminal list is generated according to the terminal device.

When the terminal device is associated to the wireless access point, the terminal list maintenance module at one side of the wireless access point can maintain the online and offline terminal list.

When it is checked that a terminal device associated with the wireless access point is online, the terminal device is added to an online terminal list.

In step S220, when the terminal device associated with the wireless access point is in an offline state, an offline terminal list is generated according to the terminal device.

When it is checked that the terminal device associated to the radio access point is not on-line, i.e. off-line, the terminal device is added to the off-line terminal list. The offline terminal list may be a history list.

In the exemplary embodiment, the corresponding terminal list can be generated according to the online state of the terminal device associated with the wireless access point, the generation mode is simple and accurate, the current state of the terminal device can be reflected, and a differentiated processing basis is provided for subsequently updating the configuration information of the terminal devices of different groups.

After an online terminal list and an offline terminal list are respectively generated according to the terminal device, the original configuration information of the terminal device in the online terminal list and the offline terminal list can also be obtained. The original configuration information is the configuration information of the terminal equipment associated wireless access point.

In step S120, when the target configuration information is acquired, a new access point is opened at the wireless access point by using the target configuration information.

In an exemplary embodiment of the present disclosure, when the original configuration information is modified on the wireless access point side, a configuration update process of the terminal devices in the online terminal list and the offline terminal list may be triggered.

In an alternative embodiment, the original configuration information includes an original service set identification and an original password, and the target configuration information includes a target service set identification and a target password. Fig. 3 shows a flow chart of two methods for opening a new access point, and as shown in fig. 3, the method at least includes the following steps: in step S310, when the original password is modified with the target password, a new access point is opened at the wireless access point using the target configuration information.

The triggering of the configuration update process of the terminal devices in the online terminal list and the offline terminal list can be realized in two ways. When the original password is modified by the target password on one side of the wireless access point, the wireless access point can open a new access point by using the newly configured target password.

The new Access Point is started by starting a new VAP (Virtual Access Point) according to the new wireless configuration.

The virtual access point VAP is a plurality of APs virtualized on a physical entity AP, each virtualized AP is a VAP, and each VAP provides the same function as the physical entity AP. Users may create different VAPs on one AP to provide wireless access services to different user groups.

If the original password is modified with only the target password, the new VAP uses the same SSID and a different wireless password. Then, the STAs are distinguished by the MAC of the VAP.

The MAC is an address used to identify the location of the network device. In an OSI (Open System Interconnection Reference Model) Model, a third layer network layer is responsible for an IP (Internet Protocol) address, and a second layer data link layer is responsible for a MAC address.

The MAC address is used to uniquely identify a network card in the network, and if one or more network cards exist in a device, each network card needs to have a unique MAC address.

In step S320, when the original service set identifier and the original password are modified with the target service set identifier and the target password, respectively, a new access point is opened at the wireless access point using the target configuration information.

The triggering of the configuration update process of the terminal devices in the online terminal list and the offline terminal list can be realized in two ways. And when the original password is modified by the target service set identifier, the wireless access point can open a new access point by using the newly configured target password.

The SSID technology can divide a wireless local area network into a plurality of sub-networks which need different authentication, each sub-network needs independent authentication, and only users who pass the authentication can enter the corresponding sub-network, so that unauthorized users are prevented from entering the network.

When the original service set identifier is modified by the target service set identifier and the original password is modified by the target password, the wireless access point can open a new access point by using the newly configured target password. And, the opening of the new access point also opens a new V AP according to the new wireless configuration.

In the exemplary embodiment, when a new access point is opened according to the target configuration information, the triggering can be triggered in two modification modes, the triggering modes are simple and accurate, and the configuration process of the wireless access point is attached, so that the practicability is extremely high.

In step S130, the original configuration information of the terminal device is updated with the target configuration information so that the terminal device associates with the new access point.

In an exemplary embodiment of the present disclosure, after the wireless access point side acquires the target configuration information, the original configuration information configuring the terminal device may be updated with the target configuration information.

In addition, since the terminal device maintains the online terminal list and the offline terminal list according to the online state, the configuration information of the terminal device can be updated for different terminal lists.

In an alternative embodiment, fig. 4 is a flowchart illustrating a method for updating a configuration of a terminal device in an online terminal list, where as shown in fig. 4, the method at least includes the following steps: in step S410, a random number corresponding to the wireless access point is obtained, and the target configuration information is encrypted by using the original password and the random number to obtain encrypted configuration information.

The random number may be generated in real time or generated by other methods, and this exemplary embodiment is not particularly limited thereto.

After the random number is acquired, the target configuration information may be encrypted using the original password and the random number.

Specifically, the Encryption processing of the target configuration information by the original password and the random number may be implemented by a DES (Data Encryption Standard) Encryption algorithm. Among them, the DES algorithm is a block algorithm using key encryption.

For the automatic update of the wireless configuration of the terminal equipment in the online terminal list, the AP side uses the DES encryption algorithm to encrypt the new target configuration information, the first bits of the required 56-bit key may be the original password, and the remaining bits are a random number, for example, 8-bit original password + 48-bit random number.

The DES algorithm has three entry parameters, namely Key, Data and Mode. Wherein, Key is 56 bits in 7 bytes, and is a working Key of DES algorithm; data is 8 bytes of 64 bits, which are Data to be encrypted or decrypted; the Mode is the working Mode of DES, and there are two modes, namely encryption or decryption.

Two principles of block cipher design are used in the DES design, namely confusion and diffusion, in order to combat the statistical analysis of adversaries on cryptographic systems.

Obfuscation is to make the relationship between the statistical properties of the ciphertext and the value of the key as complex as possible, so that the dependencies between the key and the plaintext and ciphertext are not available to the cryptanalyst.

The effect of diffusion is to apply the influence of each bit of plaintext to more output ciphertext bits as quickly as possible to eliminate the statistical structure of plaintext in a large number of ciphertexts and to spread the influence of each bit of key to more ciphertext bits as quickly as possible to prevent the key from being broken segment by segment.

After DES encryption processing is carried out on the target configuration information by using the original password and the random number, corresponding encryption configuration information can be obtained.

In step S420, the encrypted configuration information and the random number are sent to the terminal devices in the online terminal list, so that the terminal devices in the online terminal list associate with the new access point according to the target configuration information obtained by decrypting the encrypted configuration information.

After obtaining the encryption configuration information, the encryption configuration information and the random number may be sent to the terminal device in the online terminal list over the air interface (air interface).

Among wireless communication technologies, the "air interface" defines the technical specification of an electrical wave link between a terminal device and a network device, making wireless communication as reliable as wired communication.

After the terminal device in the online terminal list receives the encrypted configuration information and the random number, the encrypted configuration information may be decrypted by using the original password and the random number to obtain the target configuration information. Further, the target configuration information is used to associate with the new access point.

When the terminal device in the online terminal list uses the decrypted target configuration information to successfully associate with the new access point, the terminal device can be removed from the online terminal list.

In an alternative embodiment, when the terminal device in the online terminal list successfully associates with the new access point, the terminal device in the online terminal list is removed from the online terminal list.

And when the terminal equipment in the online terminal list is successfully associated with the new access point, the terminal equipment in the online terminal list calls the configuration storage module to store the target configuration information. In addition, the wireless access point marks the STA to complete the configuration update and removes the STA from the list of online terminals.

When the terminal device in the online terminal list fails to associate with the new access point using the decrypted target configuration information, a retransmission mechanism of the wireless access point may also be triggered.

In an optional embodiment, when the terminal device in the online terminal list fails to associate with the new access point according to the target configuration information, the encryption configuration information is sent to the terminal device in the online terminal list again.

When the terminal equipment in the online terminal list fails to associate with the new access point, the STA discards the decrypted target configuration information, and the wireless access point retransmits the encrypted configuration information to the STA.

In the present exemplary embodiment, the target configuration information is encrypted and then sent to the terminal devices in the online terminal list, but part of the information used for decryption is not transmitted, which improves the security of the target configuration information.

For the terminal devices in the offline terminal list, considering that some terminal devices are temporarily accessed, the implementation of automatically updating the access configuration of the terminal devices in the offline terminal list can be set to be completed, and then the terminal devices are associated with the new access point.

In an alternative embodiment, fig. 5 is a flowchart illustrating a method for updating a configuration of a terminal device in an offline terminal list, where as shown in fig. 5, the method at least includes the following steps: in step S510, an update time limit corresponding to a terminal device in the offline terminal list is acquired.

The updating time limit is the realization of automatically updating the access configuration of the terminal equipment in the set off-line terminal list. Also, the update time limit may be determined in consideration of sleep periods of IoT devices within the network.

For example, when the sleep period of the IoT devices in the network is one month, the update time limit may be set to one month.

In step S520, when the terminal device in the offline terminal list is on-line within the update time limit and associates the old access point corresponding to the new access point with the original configuration information, the random number corresponding to the wireless access point is obtained.

When the terminal devices in the offline terminal list come on line within the update time limit and are associated with the old access point through the original configuration information, a random number can be acquired.

In step S530, the target configuration information is encrypted by using the original password and the random number to obtain encrypted configuration information, and the encrypted configuration information and the random number are sent to the terminal devices in the offline terminal list, so that the terminal devices in the offline terminal list associate with the new access point according to the target configuration information obtained by decrypting the encrypted configuration information.

Specifically, the encryption processing of the target configuration information by the original password and the random number may be implemented by a DES encryption algorithm.

After the encryption configuration information is obtained, the encryption configuration information and the random number may be sent to the terminal device in the offline terminal list through the air interface.

After the terminal device in the offline terminal list receives the encrypted configuration information and the random number, the terminal device may decrypt the encrypted configuration information using the original password and the random number to obtain the target configuration information. Further, the target configuration information is used to associate with the new access point.

In the exemplary embodiment, the target configuration information is encrypted and then sent to the terminal devices in the offline terminal list, so that the complexity of terminal configuration access maintenance after configuration updating is simplified, the configuration of the terminal devices in the offline terminal list is updated more conveniently, and the security of the internet of things system is enhanced.

The following describes a detailed description of a method for processing configuration information in the embodiment of the present disclosure in conjunction with an application scenario.

In the related art, there may be two methods of updating configuration information of a wireless local area network. One is to change the terminal password in an NFC contact mode, and the other is to access a hotspot without configuration input in WPS and PBC modes.

First, the password can be updated in an off-line manner by replacing the password of the terminal in an NFC contact manner, and an NFC card with new configuration information needs to be updated hi in contact with the terminal with an NFC function.

Both of these two methods require configuration update operations to be performed on the terminal device one by one after the wireless access point updates the access configuration information.

However, the first method of replacing the terminal password by the NFC contact method is to wirelessly transmit an encrypted password message of an old password, and the response message is encrypted by a new password, which also requires modifying the flow of the 802.11 protocol. Compared with the prior art, the configuration information processing method disclosed by the invention does not transmit the password in the air interface, the STA can decrypt the received message to obtain the new configuration information, and the security is better.

And transmitting the WiFi password encrypted by the MAC of the connection state terminal in a broadcast and multicast mode by using a WPS (wireless personal communication system) and PBC (physical broadcast station) mode without configuration input access hotspot, and decrypting by using the MAC and replacing the original WiFi password by the terminal.

Compared with the second hotspot access mode, the configuration information processing method disclosed by the invention adopts a broadcast or multicast mode to transmit the configuration information, so that the air interface overhead is saved. In addition, the air interface transmits the encryption configuration information and the random number, and part of information used for decryption is not transmitted at the air interface, so that the security is higher.

Besides, the method for processing the configuration information can update the SSID, and the first mode of replacing the terminal password by the NFC contact mode and the second mode of accessing the hotspot without configuration input by using the WPS and PBC modes cannot be realized.

The method for processing the configuration information in the application scene comprises two main modules which are respectively positioned at an STA side and an AP side.

The main module at one side of the wireless access point comprises a terminal list maintenance module, a WLAN driving module, an encryption and decryption module and a configuration reading module. The master module at the side of the wireless access point may implement the maintenance of the online terminal list and the offline terminal list. And when the configuration of the original password or SSID is updated, calling an interface of the WLAN driving module to hide the old access point and open the access point of new configuration information, and also encrypting the new target configuration information by using the random number and the original password and sending the encrypted configuration information in an air interface.

The main module at one side of the terminal device mainly comprises a WLAN driving module, an encryption and decryption module and a configuration storage module. The main module at the side of the terminal device may receive the encrypted configuration information when updating the original password or SSID, and decrypt the encrypted configuration information to associate the newly configured access point with the decrypted target configuration information, and may also store the new target configuration information, thereby replacing the old configuration information.

Fig. 6 shows a schematic flowchart of a terminal maintenance procedure in an application scenario, and as shown in fig. 6, the terminal maintenance procedure mainly involves two modules of a wireless access point, namely a terminal list maintenance module and a WLAN driver module.

In step S610, the online terminal list is updated.

And when the terminal equipment associated with the wireless access point is in an online state, generating an online terminal list according to the terminal equipment.

When it is checked that a terminal device associated with the wireless access point is online, the terminal device is added to the online terminal list.

In step S620, it is checked whether the terminal is online.

In step S630, the terminal is put in the history list.

Fig. 7 is a flowchart illustrating an overall flow of updating configuration in an application scenario, and as shown in fig. 7, after an online terminal list and an offline terminal list are respectively generated according to terminal devices, original configuration information of the terminal devices in the online terminal list and the offline terminal list may also be obtained. The original configuration information is the configuration information of the terminal equipment associated wireless access point.

When the original configuration information is modified at the side of the wireless access point, the configuration updating process of the terminal equipment in the online terminal list and the offline terminal list can be triggered.

In step S710, the AP updates the access point configuration.

The triggering of the configuration update process of the terminal devices in the online terminal list and the offline terminal list can be realized in two ways.

When the original password is modified by the target password on one side of the wireless access point, the AP updates the password configuration of the access point.

And when the original password is modified by the target password at one side of the wireless access point and the original service set identifier is modified by the target service set identifier, the AP updates the password configuration and the service set identifier configuration of the access point simultaneously.

In step S720, the newly configured access point is turned on.

When the original password is modified by the target password on the side of the wireless access point, the wireless access point can open a new access point by using the newly configured target password. The opening of the new access point is to open a new VAP according to the new radio configuration.

And when the original password is modified by the target password at one side of the wireless access point and the original service set identification is modified by the target service set identification, the wireless access point can open a new access point by using the newly configured target password.

In step S730, the online terminal updates the access configuration.

And acquiring a random number corresponding to the wireless access point, and encrypting the target configuration information by using the original password and the random number to obtain encrypted configuration information.

And sending the encrypted configuration information and the random number to the terminal equipment in the online terminal list so that the terminal equipment in the online terminal list is associated with the new access point according to the target configuration information obtained by decrypting the encrypted configuration information.

After the encryption configuration information is obtained, the encryption configuration information and the random number may be sent to the terminal device in the online terminal list through the air interface.

And when the terminal equipment in the online terminal list fails to associate with the new access point according to the target configuration information, the encrypted configuration information is sent to the terminal equipment in the online terminal list again.

In step S740, the offline terminal updates the access configuration.

After the terminal devices in the online terminal list complete configuration update, the configuration update process of the terminal devices in the offline terminal list and the like can be entered.

And acquiring an updating time limit corresponding to the terminal equipment in the offline terminal list.

And when the terminal equipment in the offline terminal list is on line within the updating time limit and the old access point corresponding to the new access point is associated by using the original configuration information, acquiring the random number corresponding to the wireless access point.

And encrypting the target configuration information by using the original password and the random number to obtain encrypted configuration information, and sending the encrypted configuration information and the random number to the terminal equipment in the offline terminal list, so that the terminal equipment in the offline terminal list is associated with a new access point according to the target configuration information obtained by decrypting the encrypted configuration information.

In step S750, the old access point is closed.

After the configuration update of the terminal device in the offline terminal list is completed, the old access point may be closed to complete the overall flow of updating the configuration.

Fig. 8 is a flowchart illustrating a method for updating configuration of a terminal device in an online terminal list in an application scenario, where as shown in fig. 8, after target configuration information is acquired by a wireless access point, original configuration information of the terminal device may be updated and configured by using the target configuration information. In addition, since the terminal device maintains the online terminal list and the offline terminal list according to the online state, the configuration information of the terminal device can be updated for different terminal lists.

In step S810, the AP transmits the configuration information to the STA.

In step S820, the STA receives the configuration information.

The terminal devices in the online terminal list may receive the encryption configuration information and the random number.

In step S830, the STA associates using the new configuration information.

In step S840, it is checked whether the terminal in the online list completes updating.

The AP checks whether the terminal devices in the online terminal list complete the configuration update and repeats steps S810-S830 until the online terminal devices in the online terminal list are empty.

Fig. 9 is a schematic flowchart illustrating a method for updating configuration of a terminal device in an offline terminal list in an application scenario, where as shown in fig. 9, when the terminal device in the offline terminal list is on line within an update time limit and an old access point corresponding to a new access point is associated with original configuration information, an AP updates configuration information for the terminal device using an online terminal configuration update procedure shown in fig. 8.

Considering that some terminal devices in the offline terminal list are temporarily accessed, the implementation of automatically updating the access configuration of the terminal devices in the offline terminal list can be configured to be completed, and then the terminal devices are associated with the new access point.

In step S910, an offline terminal update access configuration countdown is started.

Wherein the update access configuration countdown is an update time limit. The updating time limit is the realization of automatically updating the access configuration of the terminal equipment in the set off-line terminal list. Also, the update time limit may be determined in consideration of sleep periods of IoT devices within the network.

In step S920, it is determined whether or not the time limit has elapsed.

When the update access configuration countdown does not reach the update time limit, indicating that the update access configuration is still within the update time limit; when the update access configuration countdown has reached the update time limit, indicating that the update time limit has been exceeded.

In step S930, it is checked whether the terminal completes updating in the history list.

The AP checks whether the terminal devices in the offline terminal list complete the configuration update. When the terminal equipment still exists in the offline terminal list, the terminal equipment indicates that all the terminals in the history list are not completely updated.

In step S940, offline terminal online is waited.

In step S950, the access configuration update process is completed using the online terminal.

Based on this, the AP side can maintain a terminal list, which is an online terminal list and an offline terminal list, respectively, and update in real time.

The wireless access information is modified at the AP side, wherein the original password can be modified by using the target password, or the original service set identifier and the original password can be modified by using the target service set identifier and the target password respectively.

The AP side does not directly change the configuration of the original wireless access point, but opens the new access point according to the new target configuration information, and starts the wireless configuration updating process of the terminal equipment in the online terminal list and the offline terminal list. After the wireless configuration automatic updating process is completed, the old access point is closed.

Then, the random number and the encryption configuration information are multicast-transmitted to the online STA according to the online terminal list. Specifically, the encryption configuration information and the random number are sent to the terminal device in the online terminal list through the air interface.

After the STA in the online terminal list receives the random number and the encryption configuration information, the STA may encrypt the random number and the encryption configuration information in combination with the original password to obtain the target configuration information. Further, the target configuration information is used to associate with the new access point.

And when the terminal equipment in the online terminal list successfully associates the new access point, the AP side removes the STA from the online terminal list.

Specifically, the terminal device in the online terminal list calls the configuration storage module to store the target configuration information. In addition, the wireless access point marks the STA to complete the configuration update and removes the STA from the list of online terminals.

And, the process is repeated until all terminal devices in the online terminal list access the new access point.

For the automatic update of the wireless configuration of the terminal devices in the offline terminal list, an update time limit for the offline update may be set. The updating time limit is the realization of automatically updating the access configuration of the terminal equipment in the set off-line terminal list. Also, the update time limit may be determined in consideration of sleep periods of IoT devices within the network.

And when the updating time limit is reached, waiting for the terminal equipment in the offline terminal list to be online.

After the encryption configuration information is obtained, the encryption configuration information and the random number may be sent to the terminal device in the offline terminal list point to point through an air interface.

When the terminal device in the offline terminal list is successfully associated with the new access point, the AP side may remove the terminal device from the offline terminal list. And repeating the process until the terminal devices in the offline terminal list are all accessed to the new access point or the update time limit of offline update is reached.

When the terminal device in the offline terminal list reaches or exceeds the update time limit, the terminal device needs to be manually associated to a new access point.

The method for processing the configuration information in the application scenario includes different processes applicable to the online terminal and the offline terminal, and is therefore applicable to the internet of things scenario, as well as to a common home or other conventional scenarios, which is not particularly limited in this exemplary embodiment.

When the method for processing the configuration information in the application scene is applied to a home WLAN scene, the configuration information of wireless access configuration can be automatically updated, the complexity of updating the configuration information of wireless access by Internet of things equipment is reduced, and the access of terminals of old people and children in the home WLAN scene is facilitated, so that the password changing frequency of the WLAN is improved, and the safety of the WLAN in the home scene is also improved.

According to the method for processing the configuration information in the application scene, the original configuration information is uniformly and automatically updated by using the target configuration information, the complexity of changing the wireless access configuration information by the Internet of things equipment and other terminal equipment is reduced, the terminal access process in a household scene and other scenes is facilitated, the frequency of updating the configuration information by the wireless local area network is further improved, the safety of the wireless local area network is improved, and the reflux degree of a user is improved to a certain extent.
