Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be more thoroughly understood, and will fully convey the scope of the present disclosure to those skilled in the art.

As mentioned above, when the mobile terminal currently accesses the network, if it encounters a domain name resolution error or is hijacked, the network access will fail and the network access cannot be completed. In order to solve this technical problem, an embodiment of the present invention provides a method for a mobile terminal to access a network. FIG. 1 shows a schematic flowchart of a method for a mobile terminal to access a network according to an embodiment of the present invention. As shown in FIG. 1, the method may include at least step S102, step S104, step S106 and step S108:

Step S102, monitoring network access events of the mobile terminal;

Step S104, when monitoring the network access failure of the mobile terminal, obtain the IP of the network access failure and the access domain name corresponding to the IP;

Step S106, obtaining a first correspondence between a pre-established domain name and a preset IP, and searching for a preset IP corresponding to the access domain name in the first correspondence, wherein the preset IP is different from the IP that fails to access the network; and

Step S108, using the preset IP to perform network access again.

In the embodiment of the present invention, the network access event of the mobile terminal is monitored, and when it is monitored that the mobile terminal network access fails, the IP of the network access failure and the access domain name corresponding to the IP are obtained. Then, a pre-established first correspondence between the domain name and the preset IP is obtained, the preset IP corresponding to the access domain name is searched in the first correspondence, and then the network access is performed again by using the preset IP. It can be seen that the embodiment of the present invention can obtain the preset IP corresponding to the access domain name when the mobile terminal fails to access the network, and use the preset IP to re-access the network, thereby solving the access caused by the domain name resolution error or hijacking Failed question.

The network access event mentioned in the above step S102 may be events such as data resource download, page browsing, etc., which is not limited in the present invention. In the mobile terminal, network access is performed through various applications installed on the mobile terminal, so when monitoring the network access events of the mobile terminal, the network access events of each application can be specifically monitored. For example, a mobile phone assistant application is installed on the mobile terminal, and the application usually downloads various data resources across the network, such as downloading the installation packages of applications such as games and instant messaging. Therefore, the embodiment of the present invention can monitor the data resource download event of the mobile phone assistant application.

When it is monitored that the mobile terminal fails to access the network, step S104 obtains the IP of the failed network access and the access domain name corresponding to the IP. Optionally, the IP of the network access failure here is obtained by parsing the access domain name by the DNS server. DNS is the abbreviation of computer domain name system (Domain Name System or Domain Name Service), which is composed of resolvers and domain name servers. A domain name server refers to a server that stores the domain names and corresponding IP addresses of all hosts in the network, and has the function of converting domain names into IP addresses.

Further, step S106 obtains the first correspondence between the pre-established domain name and the preset IP, and searches for the preset IP corresponding to the access domain name in the first correspondence. Here, the embodiment of the present invention provides an optional solution to Establish a first correspondence. In this optional solution, first obtain the respective domain names and IPs of multiple servers that provide network access services, and secondly cluster the respective domain names of the multiple servers, taking the same domain name as a class, Further, according to the clustering result, one or more IPs corresponding to each domain name are determined to establish a first correspondence. For example, the obtained servers that provide network access services include server 1, server 2, server 3, and server 4. Their respective domain names are domain name a, domain name a, domain name b, and domain name c, respectively, and their respective IP addresses are IP1, IP2, IP3, IP4. Then, cluster the respective domain names of servers 1, 2, 3 and 4, take the same domain name as a class, and then determine one or more IPs corresponding to each domain name according to the clustering result, that is, domain name a corresponds to IP1 and IP2 , the domain name b corresponds to IP3 and the domain name c corresponds to IP4, as shown in Table 1 below. It should be noted that the examples in Table 1 are only illustrative, and do not limit the present invention.

Table 1

In an optional embodiment of the present invention, the cloud server collects and manages the respective domain names and IPs of each server that provides network access services, which can improve the efficiency of data management. Therefore, in the above-mentioned solution for establishing the first correspondence, obtaining the respective domain names and IPs of multiple servers that provide network access services can be obtained from the cloud server actively or passively, for example, according to a specified time period (such as 1 hour or 1 day, etc.) send a request to the cloud server to obtain the respective domain names and IPs of multiple servers that provide network access services, and receive the response information returned by the cloud server containing the respective domain names and IPs of multiple servers; for example, you can receive The domain names and IPs of multiple servers that provide network access services are actively issued by the cloud server. Here, the cloud server can be actively issued regularly or irregularly. When the cloud server has the domain name and IP of the server that provides network access services When it is changed, the cloud server actively sends the change information of the domain name and IP of the server to the mobile terminal, so that the mobile terminal can dynamically update the domain name and IP of the server providing the network access service according to the change information.

In an optional embodiment of the present invention, since a first correspondence between domain names and preset IPs is pre-established, one domain name in the first correspondence may correspond to multiple preset IPs, so the network access mentioned in step S104 The failed IP may also be the preset IP from the first corresponding relationship. At this time, in step S106, when searching for the preset IP corresponding to the access domain name in the first corresponding relationship, the IP that failed to access the network should be excluded to ensure that the network access fails. The default IP will not fail to access again when re-accessing the network. For example, the IP that fails to access the network comes from the first preset IP in the first corresponding relationship, the access domain name corresponding to the first preset IP is domain name 1, and the access domain name 1 in the first corresponding relationship corresponds to the first preset IP and the second preset IP. At this time, the first preset IP needs to be excluded, and the second preset IP is selected to perform network access again. Further, since the first preset IP is an IP that fails to access the network, the first preset IP can be deleted in the first corresponding relationship, so that when the first corresponding relationship is searched for domain name resolution, the first preset IP will not be selected. The first preset IP causes network access failure.

In an optional embodiment of the present invention, if the preset IP corresponding to the access domain name found in the first correspondence relationship in step S106 includes multiple, then in step S108, when using the preset IP to re-access the network, the preset IP can be used according to the preset IP. The preferred strategy is to select a preferred IP from multiple preset IPs, and then use the selected preferred IP to perform network access again. Here, the preferred IP may be selected randomly, or the preferred IP may be selected according to the geographic location of the mobile terminal, the current network environment, etc., which will be described in detail below.

Manner 1: When selecting the preferred IP according to the geographic location of the mobile terminal, first obtain the current geographic location of the mobile terminal, and then select the preferred IP from a plurality of preset IPs whose geographic location is closest to the current geographic location of the mobile terminal.

Mode 2: When selecting the preferred IP according to the current network environment of the mobile terminal, first determine the network environment where the mobile terminal is currently located, then obtain a second correspondence between the network environment of the mobile terminal and the preset IP, and then obtain the second correspondence between the network environment of the mobile terminal and the preset IP. , selecting a preset IP corresponding to the network environment where the mobile terminal is currently located from the multiple preset IPs as the candidate IP. If there is one candidate IP, the candidate IP is used as the preferred IP; and if there are multiple candidate IPs, one candidate IP is selected from the multiple candidate IPs as the preferred IP.

The embodiment of the present invention provides an optional solution to establish the above-mentioned second correspondence, that is, first obtain one or more preset IPs included in the first correspondence, and then, based on the network environment of the mobile terminal, when the mobile terminal When in the network environment, test whether the access paths of the mobile terminal to each preset IP are connected, and then establish a second correspondence according to the preset IPs corresponding to the connected access paths and the network environment of the mobile terminal. Here, the embodiment of the present invention can establish a second corresponding relationship for each mobile terminal for different mobile terminals in combination with the actual network environment of each mobile terminal, and use the second corresponding relationship to select a preferred IP for network access again, which solves the problem. The problem of access failure caused by domain name resolution errors or hijacking. Specifically, the second correspondence established in the embodiment of the present invention can be referred to as shown in Table 2 below. It should be noted that the examples in Table 2 are only schematic and do not limit the present invention.

Table 2

Here, the implementation process of the above-mentioned mode 2 is illustrated with reference to Table 2. It is assumed that the preset IP corresponding to the access domain name a (that is, the access domain name corresponding to the IP that fails to access the network) is found in the first correspondence in step S106 as IP1 With IP2, in the mode 2, it is determined that the current network environment of the mobile terminal is network environment 2, and it is found from Table 2 that the access path of the mobile terminal to IP1 in the network environment 2 is connected, and the access path of the mobile terminal to IP2 is not connected, Then, it is determined that IP1 is the preferred IP, and then use IP1 to perform network access again. In addition, in Table 2, it is also possible to only save the preset IP corresponding to the connected access path and the network environment of the mobile terminal. ) can be deleted without saving.

In addition, the second correspondence relationship may be pre-established, or may be temporarily created at present. If the second corresponding relationship is pre-established, the second corresponding relationship has a storage time limit, and the embodiment of the present invention will dynamically update the second corresponding relationship on a regular or irregular basis. For example, as described above, the domain name and the preset IP in the first corresponding relationship will be updated (such as adding, deleting or modifying, etc.), then when the domain name and the preset IP in the first corresponding relationship are updated, the present invention implements Example will update the obtained default IP. Assuming that the preset IP is added, the embodiment of the present invention will test whether the access path of the mobile terminal to the added preset IP is connected when the mobile terminal is in a different network environment, and update it to the second correspondence; assuming that the preset IP is deleted If IP is set, the embodiment of the present invention will directly remove the deleted preset IP in the second correspondence; if the preset IP is to be modified, the embodiment of the present invention will adjust the original preset IP to the modified one in the second correspondence The preset IP is tested, and when the mobile terminal is in a different network environment, whether the access path of the mobile terminal to the modified preset IP is connected, and the second corresponding relationship is updated. For another example, considering that unstable factors existing in the network cause network access to be disconnected, the embodiment of the present invention also periodically or irregularly re-tests the connectivity of the access paths of each preset IP in the second correspondence, and retests the connectivity of the access paths. Update based on test results.

The network environment of the mobile terminal mentioned in the embodiments of the present invention may be various wireless local area networks, such as wifi, Bluetooth, etc., or may be a mobile data network provided by an operator, etc., and the present invention is not limited thereto. In general, the access efficiency in the same network environment is higher than the cross-network access. In order to further improve the network access efficiency, the embodiment of the present invention can also determine the network service operators corresponding to the preset IPs corresponding to the connected access paths, and from Among the preset IPs corresponding to the connected access paths, a preset IP that is consistent with the network environment of the network service operator and the mobile terminal is selected, and a second corresponding relationship is established. On the basis of Table 2, the second correspondence established here is shown in Table 3 below.

table 3

Here, the implementation process of the above-mentioned mode 2 is illustrated with reference to Table 3. It is assumed that the preset IP corresponding to the access domain name a (that is, the access domain name corresponding to the IP that fails to access the network) is found in the first correspondence in step S106 as IP1 and IP2, in the second way, it is determined that the network environment where the mobile terminal is currently located is network environment 1 (that is, operator A), and it is found from Table 3 that IP1 in network environment 1 corresponds to operator A, and IP2 corresponds to operator A. Business B, then determine IP1 as the preferred IP, and then use IP1 to access the network again. In addition, in Table 3, it is also possible to only save the preset IPs that are consistent with the network environment of the network service operator and the mobile terminal, and the preset IPs that are inconsistent with the network environment of the network service operator and the mobile terminal can be deleted without saving. As shown in Table 3, the network environment 1 is the operator A, and the IP2 corresponding to the domain name a in the network environment 1 can be deleted (IP2 corresponds to the operator B).

In another optional embodiment of the present invention, one of multiple candidate IPs may also be selected as the preferred IP in combination with the access speed. Specifically, the corresponding relationship between the preset IP and the access speed is stored in the second corresponding relationship, as shown in Table 4 below, so that from the second corresponding relationship, it is possible to search for the corresponding ones of the multiple preset IPs serving as candidate IPs. Access speed, select the IP with the fastest access speed from multiple alternative IPs as the preferred IP. It should be noted that Table 4 is established on the basis of Table 3, and is only used for illustration and does not limit the present invention. In practical applications, it is also possible to comprehensively select the preferred IP in combination with the operator and the access speed, and the present invention does not limit the sequence of these selection strategies.

Table 4
