Description

Access point interface configuration recovery method, device and home gateway

technical field

The present invention relates to the communication field, in particular to a method and device for recovering access point interface configuration and a home gateway.

Background technique

An important networking form of Wireless Local Area Networks (WLAN for short) is that the Access Point (AP for short) is the central device, and wireless terminals (that is, wireless clients) access the AP to realize interconnection. . In the home network, the AP is usually integrated into the home gateway (Home Gate Way, referred to as HGW) equipment, to realize the sharing of the Internet (Internet, also known as the Internet) by the internal terminals of the home, and provide wireless intercommunication services for home users platform.

Multiple virtual APs may be set on the wireless interface of the home gateway device, including a primary virtual AP and multiple secondary virtual APs, and each virtual AP corresponds to a Service Set Identifier (SSID for short). The SSID is the unique ID code broadcast by the AP to identify the AP. Simply put, it is the name of a wireless network. By configuring different information such as SSID names, encryption methods, and key values for each virtual AP, the separation of wireless LANs can be realized. Generally, the master virtual AP is used as a private virtual AP to build a private wireless network, allowing wireless terminals to directly share the Internet network, while other slave virtual APs can define different service networks according to requirements, such as only allowing access to Internet TV ( IPTV) system.

When each home gateway leaves the factory, it will preset the initial configuration of the main virtual AP, and mark the initial configuration information on the surface of the home gateway device, which is convenient for users to view and use. Users can also modify the corresponding SSID name, encryption method, and password. Key value and other information. When the user has changed the initial configuration and wants to restore the primary virtual AP to the initial configuration, Fig. 1 is a schematic diagram of a method for restoring the configuration of the primary virtual AP according to related technologies, as shown in Fig. 1, the following can be adopted in related technologies Three ways:

Method 1, log in to the web management page to restore the factory settings of the whole machine.

The so-called web management page refers to the operation page provided by the home gateway for the user to implement configuration management. In the web management mode of the home gateway, there is usually a factory reset button preset, and the user can click this button to perform a factory reset operation on the home gateway, which includes restoring all virtual AP related configurations to the factory state. The device will restart after performing the factory reset operation, and the restart time varies depending on different devices.

Method 2, using a unified reset (reset) button to restore the factory configuration of the whole machine.

The Reset button is a physical button set outside the home gateway device. Users can press this physical button to restore the home gateway device to the factory state, which includes restoring all virtual AP related configurations to the factory state. The device will restart after performing the factory reset operation, and the restart time varies depending on different devices.

Method 3, using a remote management device to restore the factory configuration of the home gateway.

In addition to the two methods described above, the remote management device can remotely manage the home gateway through the TR069 protocol. TR098 also stipulates a remote procedure call (RPC) method for remote factory restoration, through which the home gateway device can be restored. It is the factory state, which includes restoring all virtual AP related configurations to the factory state. The device will restart after performing the factory reset operation, and the restart time varies depending on different devices.

It can be seen that, the methods for restoring the initial configuration of the AP provided in the related art all adopt the method of restoring the configuration of the whole home gateway. The inventor found during the research process that the above-mentioned methods provided in the related art have at least the following disadvantages:

1. It is not possible to restore the factory configuration of the AP interface in a targeted manner, but only restore the factory state of the AP interface when the whole machine is restored to the factory;

2. After restoring the factory configuration, the whole machine will be restarted, which will affect the user experience;

3. After restoring the factory configuration, all the configurations of the home gateway need to be reconfigured, which further affects the user experience.

Aiming at the problem of poor user experience caused by restoring the configuration of the AP interface through the configuration restoration scheme of the home gateway in the related art, no effective solution has been proposed yet.

detailed description

Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.

In order to enable those skilled in the art to better understand the solutions of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is an embodiment of a part of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

The embodiment of the present invention provides an AP interface configuration recovery method, which is applied to a home gateway with a master virtual AP and a slave virtual AP. FIG. 2 is a flow chart of the AP interface configuration recovery method according to an embodiment of the invention, as shown in FIG. 2 As shown, the process includes the following steps:

Step S202, obtaining an interface configuration recovery request from the virtual AP, wherein the interface configuration recovery request carries authentication information of the primary virtual AP;

Step S204, verifying whether the authentication information is legal;

Step S206, if the authentication information is verified to be valid, restore the interface configuration of the primary virtual AP to the default interface configuration.

Through the above steps, according to the interface configuration restoration request carrying the authentication information of the legal master virtual AP, the interface configuration of the master virtual AP is restored to the preset interface configuration, thereby providing a method for AP interface configuration restoration. Compared with the method in the related art that needs to recover the overall configuration of the home gateway, other configurations of the home gateway can be retained by adopting this method, and the tedious configuration process of other configurations is avoided. It can be seen that through the above steps, the problem of poor user experience caused by restoring the configuration of the AP interface through the configuration restoration scheme of the home gateway in the related art is solved, and the user experience is improved.

Preferably, the home gateway can acquire the interface configuration recovery request through RPC, or other ways.

For example, for a wireless client supporting Hypertext Transfer Protocol (HTTP), the home gateway can receive from the virtual AP the HTTP access request sent by the wireless client connected to the virtual AP, wherein the HTTP access request uses to request a preset page; then the home gateway can access the preset page indicated by the request through HTTP, and obtain the interface configuration recovery request input by the user. This method requires the user to memorize the page address of the preset page, and send an HTTP access request to the home gateway to access the page address of the preset page when the wireless client accesses the slave virtual AP.

For another example, after the home gateway receives the HTTP access request sent by the wireless client, no matter which page the access address carried in the HTTP access request is, it will forcibly redirect the access page of the HTTP access request to the preset page ; enabling the user to generate an interface configuration restoration request through text input or button operation on the preset page, so that the home gateway receives the interface configuration restoration request input by the user through the preset page. By adopting this method, it is no longer necessary for the user to memorize the page address of the preset page, which further improves the user experience.

It should be noted here that the secondary virtual AP in this embodiment may be any common secondary virtual AP, and preferably, the AP may support the HTTP protocol. In order to make full use of the feature that the slave virtual AP is isolated according to the service, a dedicated slave virtual AP can be used for interface configuration recovery of the master virtual AP. For example, the dedicated secondary virtual AP is an open AP, and any wireless device can access the dedicated secondary virtual AP as long as its IP address allocation meets requirements. A public key can be set from the virtual AP, and even direct access without key verification is possible. In addition, in order to ensure the security of the wireless devices accessing the slave virtual AP, it can be set that the wireless devices accessing the dedicated slave virtual AP cannot communicate with each other.

Preferably, when it is verified that the authentication information is illegal, the home gateway can return the authentication failure information from the virtual AP, and record the number of authentication failures in a certain period of time; When the number of times exceeds the preset value, a timer can be started, and before the preset time arrives (that is, before the timer expires), the validity verification of the authentication information is no longer performed. The method of not performing legality verification includes: closing the relevant interface/interface for obtaining the interface configuration restoration request, or directly discarding the interface configuration restoration request received before the preset time arrives.

Preferably, this embodiment also provides a way for the wireless client to access the slave virtual AP, for example, the home gateway receives the access request of the wireless client that will send the interface configuration recovery request to access the slave virtual AP; The Dynamic Host Configuration Protocol (DHCP) method assigns IP addresses to wireless clients that automatically obtain IP addresses; in the case of successfully assigning IP addresses to wireless clients that automatically obtain IP addresses, connect unlimited clients to the slave virtual AP. Or, the home gateway receives the access request of the wireless client that will send the interface configuration recovery request to access the slave virtual AP; judge whether the IP address of the wireless client whose IP address is manually set is the IP address in the preset address pool of the home gateway; When it is judged that the IP address of the wireless client whose IP address is manually set is an IP address in the home gateway's preset address pool, and the IP address manually set by the wireless client does not conflict with the IP addresses of other devices connected to the home gateway Next, connect wireless clients from the virtual AP.

Preferably, the above authentication information includes: a point-to-point protocol over Ethernet (PPPoE) dial-up account required by the home gateway to access the Internet, and a preset key value of the master virtual AP. Wherein, the preset key value of the main virtual AP can generally be obtained from the housing of the home gateway.

In this embodiment, an AP interface configuration recovery device is also provided, which is applied to a home gateway with a master virtual AP and a slave virtual AP, and is used to implement the above embodiments and preferred implementation modes, and those that have already been explained will not be repeated. , the modules involved in the device will be described below. As used below, the term "module" may be a combination of software and/or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

Preferably, the acquisition module 22 includes: a first receiving unit, configured to receive an HTTP access request from the virtual AP; a redirection unit, coupled to the first receiving unit, configured to redirect the access page of the HTTP access request to a preset page ; The second receiving unit is configured to receive an interface configuration recovery request input by a user through a preset page.

Preferably, the device further includes: a first processing module, coupled to the verification module 34, used to return authentication failure information and record the number of authentication failures when the verification module 34 verifies that the authentication information is illegal; If the number of authentication failures exceeds the preset value, the verification of the validity of the authentication information will not be performed before the preset time arrives.

Preferably, the device further includes: a receiving module, configured to receive an access request from a wireless client that sends an interface configuration restoration request to access the slave virtual AP; a second processing module, coupled to the receiving module, configured to automatically The wireless client that obtains the IP address assigns an IP address; or judges whether the IP address of the wireless client that manually sets the IP address is an IP address in the preset address pool of the home gateway; the access module is coupled to the second processing module for After successfully assigning an IP address to a wireless client that automatically obtains an IP address; or judging that the IP address of a wireless client that has manually set an IP address is an IP address in the preset address pool of the home gateway, and the IP address manually set by the wireless client If the IP address of other devices connected to the home gateway does not conflict, connect the wireless client to the virtual AP.

Preferably, the above-mentioned authentication information includes: a PPPoE dial-up account required for the home gateway to access the Internet, and a preset key value of the master virtual AP.

This embodiment also provides a home gateway, including: the above-mentioned AP interface configuration recovery device.

In addition, each functional unit in each embodiment of the present invention may be integrated into one processing unit, each unit may exist separately physically, or two or more units may be integrated into one unit. The above-mentioned integrated units can be implemented in the form of hardware or in the form of software functional units.

In order to make the description of the embodiments of the present invention clearer, the following describes and illustrates in conjunction with preferred embodiments.

This preferred embodiment provides a method for recovering the configuration of the AP interface of the home gateway, so as to overcome the problem in the prior art that the configuration of a specific virtual AP cannot be restored in a targeted manner. In this preferred embodiment, a method for implementing configuration recovery of the primary virtual AP by using the secondary virtual AP as an access point is provided.

The method for recovering the master virtual AP by using the slave virtual AP provided in this preferred embodiment includes the following steps:

Step 1. In addition to enabling the master virtual AP by default on the physical AP interface of the home gateway, at least one slave virtual AP needs to be enabled. As an open access point, the slave virtual AP does not configure encryption, and any wireless client can associate with the slave virtual AP;

Step 2, when the wireless client associates with the slave virtual AP and conducts HTTP service access, the home gateway redirects the HTTP access page to the home gateway (on a preset fixed page, this page contains the authentication necessary to restore the master virtual AP to the factory state Information input box and action execution button;

Step 3: The user enters the correct authentication information on the redirection page and submits it. After the home gateway passes the authentication, it can restore the main virtual AP to the factory state. Among them, the whole process will not affect other modules and applications, and the home gateway will not restart;

Step 4, after the home gateway detects the wrong authentication information, it will return the information prompt of authentication failure through the page, and allow the user to re-authenticate;

Step 5: The home gateway limits the number of authentication failure retries. After the number of authentication failures reaches the upper limit, the authentication condition input box and the recovery button on the redirected page will be grayed out, and the user is no longer allowed to perform recovery operations. At the same time, the home gateway Specifies the recovery time for lifting the restriction.

Preferably, in step 1, the SSID name of the slave virtual AP has been preset and can correspond to the name of the master virtual AP. The wireless client can search for associated APs within the wireless coverage of the home gateway. At the same time, the home gateway assigns an IP address to the wireless client through DHCP. If the IP address of the wireless client is manually configured, it must be consistent with the address in the home gateway’s preset address pool. , otherwise no response will be made;

Preferably, in step 2, the wireless client associated with the virtual AP is not allowed to access services other than HTTP, and will be redirected to a specified page when HTTP services are accessed. In addition, the slave virtual AP is isolated from other LAN-side interfaces (including wired interfaces and other virtual AP interfaces). Preferably, any form of communication cannot be performed between wireless clients associated with the slave virtual AP.

In steps 2 and 3, the authentication information on the redirection page includes the PPPoE dial-up account required for the home gateway to access the Internet and the default factory key value of the main virtual AP. The home gateway stores the authentication information in the database and the configuration file. After the user enters the authentication information, the home gateway will compare the input value with the stored authentication information. If they are consistent, the authentication is passed, and the operation of restoring the default configuration of the main virtual AP can be further performed. As described in step 3; if they are inconsistent, an error message will be displayed to inform the user of the reason for the failure, as described in step 4. The prompt information here can be displayed on the current authentication page, or a new prompt page can pop up. It is better to specify the reason for the failure in the failure message, so that the user can accurately correct the input information.

In step 5, the home gateway limits the number of authentication failures. The home gateway sets a counter and a timer, and can preset the upper limit of the counter and the timeout time of the timer. Each time the authentication fails, the counter is incremented by one, and at the same time, it is judged whether the current accumulated value of the counter reaches the upper limit value. If the upper limit value is not reached, the user will be prompted the reason for the authentication failure through the page, and the user is allowed to re-enter the authentication information, as in step 5 If the cumulative value has reached the upper limit, the user will be notified that the maximum number of authentications has been reached, and the authentication information input box and the recovery button will be grayed out, and the timer will be started, and the authentication will not be re-entered until the timer reaches the timeout period information, and perform recovery operations.

The preferred embodiments of the present invention are described and illustrated below in conjunction with the accompanying drawings.

Fig. 4 is a schematic flow diagram of a master virtual AP configuration restoration method according to a preferred embodiment of the present invention. As shown in Fig. 4, the flow includes the following steps:

In step S401, the home gateway detects that there is a wireless client accessing the secondary virtual AP access point. Generally, the slave virtual AP is an open access point without encryption configured, and the name of the slave virtual AP is associated with the name of the master virtual AP, so that when there are multiple slave virtual APs, they can be quickly distinguished. For example, the name of the master virtual AP is SSID1, and the name of the slave virtual AP is SSID1-HELP. In addition, the wireless client is installed with a browser, which supports HTTP access function. After accessing the secondary virtual AP, the wireless client can automatically obtain the private IP address assigned by the home gateway, or manually set an IP address consistent with the address pool of the home gateway, but cannot access all services other than HTTP, and cannot communicate with other LAN-side interfaces ( Including the wired interface and other virtual AP interfaces) to communicate, that is, the slave virtual AP is isolated from other LAN side interfaces.

Step S402, when the wireless client accesses the HTTP service, the home gateway does not forward the service according to the normal process, but pushes it to an authentication page forcibly. For example, when a wireless client accesses "www.xxx.com", the home gateway will forcibly guide the access page to the specified authentication page. Fig. 5 is a schematic diagram of an authentication page according to a preferred embodiment of the present invention. As shown in Fig. 5, the page includes an authentication information input box, related prompt information, and an action button.

Step S403, the home gateway receives the authentication information submitted by the user, including the dial-up account of the home gateway's current PPPoE connection and the key of the default master virtual AP. The key for the default master virtual AP is available on the home gateway shell label. Since the key of the default main virtual AP of each home gateway is unique, and the PPPoE dial-up account of each user is also unique, so using this as an authentication condition can fully guarantee the security of information.

Step S404, the home gateway starts the counter immediately after receiving the authentication information, and compares the PPPoE dial-up account stored in the database with the default configuration file and the key of the main virtual AP, if the data is consistent, the authentication is passed, and the configuration of the main virtual AP Restore to the factory default state, while keeping other user configurations unchanged, and other services will not be affected; if the data is inconsistent, the authentication will fail, and the reason for the authentication failure will be prompted through the page (such as PPPoE account error, default AP key error, etc.) , while the counter is incremented by one.

In step S405, the home gateway judges the counter value in step S404. If the number of times exceeds the limit (for example, three times), it will prompt through the page that the limit for authentication has been exceeded, and gray out the authentication information input box and the recovery button to prevent the user from repeatedly operating . Start the timer at the same time, keep the graying state until the timer expires, and automatically release the graying after the timer expires, allowing the user to re-enter the authentication information and operate the recovery button, that is, restart the process of step S403 and below; if the limit is not exceeded times, it is allowed to continue the process of step S403 and below.

To sum up, through the above-mentioned embodiments and preferred embodiments of the present invention, using the method of recovering the configuration of the master virtual AP from the virtual AP, compared with the prior art, not only the directional restoration of the configuration of the master virtual AP is realized, but also Through the page authentication, the security of the operation is fully guaranteed, and the whole machine will not be restarted, and the user experience effect is obviously improved.
