Preferred embodiment of the invention

In order to solve the problem that the related art cannot recover the network connection due to the abnormality of the Internet access parameter, the embodiment of the present invention provides a method and an apparatus for restoring the network connection. The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

1 is a flowchart of a method for restoring a network connection according to Embodiment 1 of the present invention. As shown in FIG. 1, the method includes the following steps:

Step 101: Back up the Internet access parameter when the Internet parameter setting is completed and the network is normally connected.

In this step 101, the Internet access parameter may include at least one of the following:

The service set identifier SSID and password for accessing other access point APs, the firewall rules for network connections, and the network connection mask list.

In addition, the foregoing step 101 may be configured to determine whether to back up the Internet access parameter according to the operation of the user. Specifically, after the Internet parameter setting is completed and the network is normally connected, the message prompting the backup Internet access parameter is displayed on the terminal interface that performs the network connection, and is received. When the user operation indicates that the Internet access parameters are backed up, the Internet access parameters are backed up. Otherwise, the Internet access parameters are not backed up. Here, the user operation may be an operation of inputting an indication signal by the user through the Internet terminal. The user operation is specifically limited. Those skilled in the art can understand that the user operations herein can be used by various current Internet terminals to receive an operation performed by the user to indicate whether to back up the Internet access parameters.

When the user uses the mobile terminal product for the first time to access the Internet, you need to set the corresponding Internet access mode and the corresponding Internet access parameters. The Internet access parameter configuration is complete, and the user performs the action of connecting to the network (the user's WAN port is inserted into the network cable in DHCP mode). , there will be a display connection on the UI. Gong, such as the Connected logo (text or icon). At this time, the background will be connected according to the current dialed state, and it is determined whether the current Internet access mode and the Internet access parameter exist in the preset backup Internet access parameter. If not, the backup operation is performed. Similarly, each time the user voluntarily modifies the Internet access parameters and the dialing is successful, the background parameters of the Internet access are triggered. If it is determined that the corresponding Internet access parameters are not backed up, the entry is backed up.

When the user modifies the Internet access parameters actively or by mistake, the dialing is unsuccessful and the network cannot be connected. In this case, the background will give a prompt to prompt the user to use the backup parameters for recovery. If there are multiple ways to access the Internet, a list of users can be given for the user to choose. Users can use the connection list to perform networking operations, or use the recovery function to let the background itself try to configure parameters and network from the backup entries. If the network is successful, the user's current networking mode is given. If it fails, perform a simple network diagnosis for your reference.

In the foregoing step 101, the setting of the Internet parameter setting may be specifically: the timing when the Internet access parameter is modified, or the Internet access parameter set when the device first performs the network connection, for example, if the mobile device is powered on for the first time, the user sets the Internet access. The mode, that is, the network connection mode and the corresponding Internet access parameter, or when the Internet access mode needs to be changed, the user modifies the Internet access parameter, and after the configuration is completed, implements the network connection operation (such as SIM card/PPPOE dialing action, WAN port insertion network line action), network connection Normally, the background will back up the new Internet access method and other corresponding Internet access parameters, that is, the Internet access mode is also one of the Internet access parameters. If the Internet access parameter set by the user cannot complete the network connection, you can obtain the Internet access recovery function from the previously backed up Internet parameter entry to perform the network connection recovery operation, and try to restore the Internet access parameter, which is allowed or selected by the user (if there are multiple Internet access methods) The situation) uses an internet access method in the Internet parameter list.

The backup of the Internet access parameter can be performed after the user manually modifies the Internet access parameter. If the normal network connection can be established after the Internet access parameter is modified, and the Internet access parameter is not backed up, the Internet access parameter is backed up. If the network connection cannot be established after the Internet access parameter is modified, the Internet access parameter that the user can make a network connection is provided for the user to select. If the feasible Internet access parameter cannot be found from the backup Internet access parameter, the cause of the network abnormality is diagnosed. For example, the WAN port should be plugged into the network cable, but it is not inserted. In this case, the user needs to be prompted to insert the network cable, and then continue to try to recover the Internet parameters.

After the network connection is normal, determine whether the current Internet access mode and the corresponding Internet access parameters have been backed up. If not, backup the Internet access parameters corresponding to the current Internet access mode. The user should restore the factory settings and upgrade the application version. The partitions of the corresponding parameter storage will be erased. Therefore, the backup location must be a partition that cannot be erased. The size of the partition can be occupied by 10-20 backup records, which does not exceed 2M. The partition can also be used to store preset Internet access methods and parameter entries.

Steps for judging whether the network is normal in the background: Generally, first, setting the value of the network state according to the mobile terminal device, for example, when the dialing action is successfully dialed, setting a dialing success identifier to identify that the current dialing is successful. After determining that the dialing is successful, determine whether the public IP address is obtained. If the public IP address is obtained successfully, you can use ping (Network Diagnostic Tool) to check whether the preset website can connect to the network. The judgment results that can be obtained in the above various judgment steps can be used as the basis for whether the current network connection is abnormal. The background can select at least one of the steps to determine whether the network is normal.

Specifically, the timing of determining whether the network is abnormal may be: when the Internet access mode or other Internet access parameters are changed. For example, if the network connection fails for the first time, if the network connection fails, the user prompts will be given when the network cable is in the correct state. You need to contact the carrier for support. When the parameters of the PPPOE change, such as the account and password changes, and this change is not what the user wants, this may be caused by the user's and other users' misoperations. In this case, the online parameter recovery operation is required. .

The backup Internet access parameter can be used for the case where there is a misoperation or the user cannot complete the parameter setting. The user attempts to restore the network connection by selecting the Internet access parameter from the backup Internet parameter entry through the webpage or the UI or the combination key of the computer. The command only needs to click the button to restore the Internet parameter on the UI, or call the same background interface defined by the combination key to perform the online parameter attempt recovery operation. That is, the user performs a recovery operation, invokes a background interface according to the operation, and queries the backup Internet access parameter entry in the background to determine the process of the online parameter. During the specific query process, you can first query the Internet access parameters corresponding to the current Internet access mode. If the network connection can be restored, the user prompts or the user selects. If the Internet access parameter is not queried based on the current Internet access mode, the Internet access parameter corresponding to other Internet access modes is queried. If there is more than one available Internet access parameter, the user prompts for the user to select, and if the available Internet access parameter is not queried, The user network abnormality diagnosis result is obtained, so that the user performs the corresponding operation for the network abnormality reason, and then restores the network connection by querying the available online parameter.

Optionally, the backup Internet access parameter can be used for querying by the user, and the identifier of the Internet access parameter can be presented. To the user, so that the user can select the Internet access parameters by themselves, or directly, the backup Internet access parameter items are presented on the UI for the user to select.

Step 102: When the network connection is abnormal, use the Internet access parameter to perform network connection.

In the step 102, the network connection using the Internet access parameter may specifically include:

If the mobile terminal device is used, the Internet access method is replaced. If the PPPOE cable broadband dialing method is used before the Internet access method is replaced, then the SIM card dialing mode of the 3G/4G package is used. In this case, the Internet access parameter of the device backup can be There are more than two types. For example, if the operator's SIM card is replaced, the corresponding APN parameters may also change. Therefore, even if the same Internet access method is used, different Internet access parameters may need to be backed up. Each time a new Internet access method is used, The background will query whether the backup entry has a backup of the Internet access parameters corresponding to the Internet access method. If not, the corresponding Internet access parameters are backed up. Therefore, when the network connection is abnormal, there may be multiple online access parameters available for backup in the device. In this case, you need to select these available Internet access parameters. You can select the following methods:

If there are at least two networks to be connected based on the backup Internet access parameters, the network with low tariffs in the network to be connected is preferentially selected for network connection, or the preferentially connected network preset by the user is preferentially connected, or according to the network currently selected by the user. Make a network connection.

Optionally, the method further includes: obtaining the currently available Internet access parameter in the pre-backed Internet access parameter, and providing the obtained online access parameter to the user, if the network parameter setting is completed and the network is still unable to connect; If the access network parameter network still cannot be connected, determine the reason why the network cannot be connected, and prompt the user why the network cannot be connected.

In order to further improve the user experience, the process of using the backup Internet access parameter to perform the network connection may be set to be visible to the user and confirmed by the user whether to perform the process. Based on this, the method for restoring the network connection in this embodiment may further include: using the Internet access parameter Before the network connection is made, the message of the Internet parameter recovery and the available Internet access parameters are prompted on the terminal interface, and after receiving the user operation, the network connection is indicated by using the Internet access parameter indicated by the user operation. There are at least two networks to be connected based on the backup Internet access parameters, specifically the network that can be connected by using the backup Internet access parameters, and the two types of networks to be connected, specifically the types of different networks, for example, through traditional data cards. , uFi, CPE, or router to connect to the network.

In addition, since the Internet access device may have more Internet access parameters, when the current network connection needs to obtain the Internet access parameter, the keyword search method may be used to obtain the corresponding Internet access parameter, thereby improving the efficiency of obtaining the corresponding Internet access parameter. In step 102, using the Internet access parameter for network connection, the method may further include:

The keyword used to find the corresponding Internet access parameter is determined according to the network connection mode of the current network to be connected, and the Internet access parameter of the current network to be connected is searched for by using the keyword in the online parameter of the backup, and the network connection parameter is used to perform network connection.

The method for restoring the network connection according to the embodiment of the present invention can diagnose the abnormality of the network connection, and the specific diagnosis method is as follows:

Before using the Internet access parameter to connect to the network, determine the cause of the abnormal network connection according to the historical Internet access parameters of the terminal that performs the network connection and the data of the backup Internet access; and prompt the user to provide the network connection guidance information according to the determined network connection abnormality.

Example 2

The second embodiment provides a method for restoring the Internet access parameters, which is the same as the method for restoring the network connection of the embodiment 1. It discloses the more technical details of the method of the present invention to more clearly describe the present invention. The specific implementation process. It should be noted that the present embodiment is a preferred embodiment, and the disclosure is not intended to limit the implementation of the present invention.

In this embodiment, the function of restoring the correct configuration of the last network connection is added to the UI of the traditional data card/uFi/cpe, so that the embedded Internet access device can automatically back up the relevant Internet access parameters. As shown in Figure 2, after the operator's technical personnel or users set the Internet access mode and Internet access parameters, the network connection is normal, and the embedded Internet access device background will automatically back up the relevant parameters of the Internet access. For example, the Internet access mode is PPPoE (Point- To-Point Protocol over Ethernet, point-to-point protocol dialing on Ethernet, the corresponding PPPoE account and password and PPPOE Internet access mode are backed up. When the user modifies the Internet access mode, for example, if the user uses the SIM (Subscriber Identity Module) card and sets the corresponding APN parameters, the Internet access is normal, and the Internet device backend will back up the mobile phone number/IMSI of the SIM card (International Mobile SubscriberIdentification Number). , the international mobile subscriber identity), and the corresponding APN parameters, when the SIM card is inserted again next time, the Internet access parameters corresponding to the entry are preferentially restored from the backup entry for the user to use.

The backup related online parameters in this embodiment can also be used for backup and restoring other related parameters, for example, the SSID and password of other APs, the firewall rules, and the black and white list of wifi can be backed up.

The backup related Internet access parameters can be operated through the UI. The traditional data card can be used for network connection. The UI and uFi and CPE can restore the Internet access parameters through the Web UI. The backup operations can be automatically completed by the background. In addition, it can also be implemented by setting a hardware combination key. The combination key is used to quickly restore the Internet access mode and the corresponding Internet access parameter, and based on the combination key, there is no need to restore the Internet access parameter operation on the UI. That is, if the network connection can be restored only by the key combination, the user does not need to open the UI. For example, the way to restore instructions is entered via a button on the device. Perform recovery operations such as Internet/firewall rules/wifi black and white lists. In addition, the online backup parameters of the background backup are backups after the network connection is normal, and the background parameters of the network can be backed up in advance, so that when the user first uses the Internet access device, the network connection operation can also be performed based on the online parameters that are backed up in advance, which is convenient and quick. . It should be noted that the backup Internet access parameters must be correct, otherwise the background will return a backup failure message.

The above process of restoring parameters such as the Internet may optionally be set to be visible to the user. If the user is invisible, the system needs to be designed to automatically back up and restore the Internet access parameters.

The abnormality of the network connection may be caused by other reasons except the abnormal Internet access parameters. Therefore, after the other abnormal causes are resolved, the Internet access parameters are used for network connection. Based on this, the above method also includes: Before the network connection, if the cause of the abnormal network connection is detected and is not related to the Internet access parameter, the user is prompted for the cause of the abnormal network connection.

In the above process of restoring the Internet access parameter, if the user's network cable socket is not in the correct position, the user should be prompted to change the network cable to the correct socket position, and try again after the network cable socket is correct, as shown in FIG.

In the above process of restoring parameters such as accessing the Internet, if there are two or more types of Internet access that can be accessed online, the priority is selected according to the lowest tariff. To ensure the correctness of the minimum judgment of the tariff, all the schemes are required for the user to select. Or try to use the cpe Internet terminal device as an example, as shown in Figure 4, according to a certain method set by the user.

The above process of restoring the Internet access parameter can perform keyword query recovery on the entry of the backup parameter. When using the traditional data card, the mobile phone number/IMSI number is used as a keyword query, as shown in FIG. 5, uFi, In addition to the mobile phone number/IMSI number of the SIM card, the CPE and the router can also perform keyword query according to the Internet access method, especially when judging that there is no SIM card, directly querying the Internet access mode. If the Internet access device has a GPS positioning function, the location message can be used as a judgment condition for storage, which is equivalent to the SIM card mobile phone number/IMSI number. When the lowest tariff is determined, it can also determine whether it is roaming according to the GPS positioning.

The above process of restoring the Internet access parameter may also be used as a diagnosis for the reason that the network cannot be connected. According to the configuration parameters of the previous Internet access of the terminal, the corresponding judgment basis is matched in the background, combined with the backup Internet access parameters, to jointly diagnose the reason that the network cannot be connected, to the user. Prompt the network connection guide information to guide the user to complete the configuration of the Internet access parameters, as shown in Figure 6.

On the Internet devices such as traditional data cards, uFi, CPE, and routers, back up the correct Internet access parameters. When a network connection is abnormal, the user can perform the action of restoring the Internet operation through the UI or hardware combination key. The background will automatically backup from the backup. Find the relevant Internet access parameters in the entry and try to re-establish the network connection. If the network connection is successful, return the relevant parameters of the current Internet access. If all the entries are unsuccessful, the user will return the failure. The user/operator technical support or later try.
