Description

Method and device for assisting client in wireless network switching
Technical Field
The present disclosure relates to the field of computer information processing, and in particular, to a method, an apparatus, an electronic device, and a computer readable medium for assisting a client in performing wireless network switching.
Background
When the PC of the Windows system is accessed to the network, the DNS configuration of the network card can be selected to be obtained automatically and configured manually. If the user does not perform manual configuration, the system selects an automatic acquisition mode, so that an automatic acquired DNS server is used; if the user has manually configured, a manually configured DNS server is used.
When the PC is connected to the wireless network, the PC can be switched among different wireless networks, the PC can save the configuration data of the connected wireless network, if the DNS configuration data A of the network card is manually set when the PC is connected to a certain wireless network A, the configuration data A which is saved before is also extracted from the configuration data when the wireless network A is connected again, and then the original DNS configuration A which is manually set is reused in the wireless network A.
When the PC accesses the wireless network, if it switches to a new wireless network B, the new wireless network B multiplexes DNS configuration C set by the wireless network C connected last time, which is a normal phenomenon. If the connection is switched to the connected wireless network a, the DNS configuration C manually set by the wireless network C connected last time is not normally multiplexed, but there is a certain probability that the DNS configuration C of the wireless network C connected last time is multiplexed. If the DNS configuration C of the last connected wireless network C is the DNS of the auto-get configuration and the newly switched wireless network a is also the auto-get configuration, the wireless network a can continue the normal network access. However, if DNS configuration C of wireless network C connected last time is a DNS configured manually, there may be a problem that a user cannot make network access regardless of whether newly switched wireless network a is configured manually or automatically.
When the PC is accessed to the wireless network, the PC is switched to a connected wireless network, if the problem of multiplexing the manually set DNS configuration of the last connected wireless network occurs, the user can only modify the manually set DNS configuration and then can normally access the DNS

While the web page end provided to the user for web services is typically located in the terminal devices 101, 102, 103.
The inventor of the present disclosure finds that all network cards on the PC have corresponding entries in the registry, and the entries include key values for configuring information of the corresponding network card.
The paths in the registry are as follows:
X\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\
the sub items in the path respectively represent the corresponding network cards on the PC, and the key values contained in the sub items are the configuration information of the corresponding network cards.
If the network card table entry contains a key value pair with the key of DhcpNetworkHint, the network card is a wireless network card, and the key value contained in the network card table entry corresponds to the configuration information of the currently active wireless network. The "NameServer" key in the network card entry represents information of the DNS configuration set manually. If the PC has been previously connected to another wireless network, the network card entry will include a subordinate subitem, where the name of the subitem is consistent with the value in the key value pair with the key "dhcpnetwork hit". And obtaining the configuration information of the wireless network connected before the key value contained in the sub item corresponds to the data.
If the PC is switched to a wireless network connected before, the key value pair data contained in the current wireless network card can be changed into the data of the subordinate sub-items, and the key value pair data contained in the sub-items corresponding to the newly connected wireless network can be changed into the key value pair data contained in the wireless network card table items. That is, when the active network changes, the key value and the data included in the wireless network card table item indicating the active network also change.
If the PC is switched to a new wireless network, the key value pair data contained in the current wireless network card can be changed into the data of the lower sub-item, and the key value pair data corresponding to the newly connected wireless network can be changed into the key value pair data contained in the wireless network card table item. I.e. the wireless network card will add a sub-item representing the previously connected wireless network.
The registry structure is shown in fig. 2. The inventor of the present disclosure finds that the network card configuration information of the PC may be obtained from the data by reading the key value included in the network card entry in the registry, or the configuration information of the network card may be set to the data by modifying the key value included in the network card entry in the registry.
Fig. 3 is a flow chart illustrating a method of assisting a client in wireless network handoff according to an exemplary embodiment. The method 30 for assisting the client in performing the wireless network handover at least includes steps S302 to S308.
As shown in fig. 3, in S302, the network connection state of the client is monitored. After the client logs in, whether the PC connection is a wireless network or not is judged, and if the PC connection is the wireless network, the change of the PC network state is monitored.
More specifically, the method used in the present disclosure may be applied to a user authentication platform that assists a user in surfing the internet, where the user needs to log on to the platform for user authentication, thereby obtaining rights to access the internet. The method used in the present disclosure may be set in the client terminal by means of program embedding, and more specifically, may be set in a user authentication application that assists a user in surfing the internet.
In S304, when the network connection state of the client is changed, configuration information of a wireless network currently used on the client is acquired. Comprising the following steps: extracting a registry of the wireless network card of the client; extracting a network card table item from the registry; and extracting configuration information of the currently used wireless network based on the key value pair corresponding to the network card table item.
As can be seen from the analysis shown in fig. 2, the client uses the variable list of the linked list structure to store the network configuration data related to the wireless network card, the configuration data of the wireless network currently connected to the PC is set as the first item of the linked list, and if the list item corresponding to the wireless network card has a subordinate sub-item (i.e. the wireless network connected before), the configuration data of the sub-items are sequentially stored in the linked list.
When the client monitors that the PC network state changes, the client indicates that the PC switches the wireless network connection. The client side can firstly acquire the first item in the list, the item corresponds to the last connected wireless network, the value of the key value pair with the key of DhcpNetworkHint in the item is taken, the path of the item in the registry is obtained, the data corresponding to the item in the registry is read again, and the data in the list is updated. This is to ensure that the latest configuration data can be backed up when the DNS configuration is manually modified by the user.
For example, the name of the currently active wireless network card may be obtained, an entry corresponding to the wireless network card in the registry may be found by the name, where the key value data included in the entry of the wireless network card corresponds to the configuration data of the currently connected wireless network (i.e. the active wireless network), and if the PC is previously connected to another wireless network, the entry may have a corresponding lower sub-entry, and the key value data included in each sub-entry corresponds to the configuration data of the previously connected wireless network.
In S306, the configuration information of the wireless network and the configuration information of the backed up plurality of wireless networks are matched. And acquiring configuration data of the currently active wireless network, searching whether backup of the wireless network data exists in the list through a key value of a key value pair of DhcpNetworkHint, and if no backup indicates that the currently active wireless network is a newly accessed wireless network, setting the configuration data of the currently active wireless network as a head of the list because the newly accessed wireless network multiplexes the DNS configuration manually set by the last connected wireless network.
In S308, when the matching is consistent, the current configuration information is restored based on the backed up configuration information to ensure that the client continues network connection.
In one embodiment, further comprising: and when the matching is inconsistent, taking the configuration information of the currently used wireless network as a preference.
If the list has backup to indicate that the currently active wireless network is the wireless network connected before, the value of the key value pair with the key of 'NameServer' in the backup is compared with the value of the key value pair corresponding to the currently active wireless network table item, if the same indicates that the manually set DNS configuration is not multiplexed. And if the values are different, modifying the corresponding values in the currently active wireless network table items by using the backed-up values, and recovering the original data of the DNS configuration which is manually set so as to solve the multiplexing problem. The backup of the wireless network data currently active in the list is set as the first item of the list.
According to the method for performing wireless network switching by the auxiliary client, the network connection state of the client is monitored; when the network connection state of the client is changed, acquiring configuration information of a wireless network currently used on the client; matching the configuration information of the wireless network with the backed up configuration information of a plurality of wireless networks; and when the matching is consistent, recovering the current configuration information based on the backed-up configuration information to ensure that the client continues to be connected with the network, monitoring the change of the network state at the client, and correcting the network multiplexing condition of the client when the client performs wireless network switching so as to ensure the correct operation of the network at the client.
It should be clearly understood that this disclosure describes how to make and use particular examples, but the principles of this disclosure are not limited to any details of these examples. Rather, these principles can be applied to many other embodiments based on the teachings of the present disclosure.
Fig. 4 is a flow chart illustrating a method of assisting a client in a wireless network handoff according to another exemplary embodiment. The flow 40 shown in fig. 4 is a complementary description of the flow shown in fig. 2.
As shown in fig. 4, in S402, a login request from a client is received and processed. The client may, for example, send a login request to a user authentication server.
In S404, after the client logs in, a network connection state of the client is obtained. The client uses the variable list of the linked list structure to store the network configuration data related to the wireless network card, and the configuration data of the wireless network currently connected with the PC is set as the first item of the linked list. As shown in fig. 2, the storage locations of the configuration data may be: the sub-items in the path respectively represent the corresponding network cards on the PC, and the key values contained in the sub-items correspond to the configuration information of the network cards.
In S406, when the network connection state is a wireless network connection, the network connection state of the client is monitored. Comprising the following steps: extracting a registry of the wireless network card of the client; extracting a network card table item from the registry; and determining that the network connection state of the client is wireless network connection when the network table item comprises preset key value pairs.
More specifically, if the network card table entry includes a key value pair with a key of "dhcpnetwork hit", it indicates that the network card is a wireless network card, and the key value included in the network card table entry corresponds to configuration information of the currently active wireless network. The "NameServer" key in the network card entry represents information of the DNS configuration set manually. If the PC has been previously connected to another wireless network, the network card entry will include a subordinate subitem, where the name of the subitem is consistent with the value in the key value pair with the key "dhcpnetwork hit". And obtaining the configuration information of the wireless network connected before the key value contained in the sub item corresponds to the data.
In S408, the network configuration data of the wireless network card of the client is backed up. Comprising the following steps: acquiring the identification of the currently used wireless network of the client; and extracting network configuration data of the wireless network card of the client from the registry based on the identification.
The method for extracting the network configuration data of the wireless network card of the client from the corresponding table entry in the registry based on the identification comprises the following steps: determining a corresponding entry in the registry based on the identification; and extracting network configuration data of the wireless network card of the client based on the linked list structure of the table items.
In S410, after the client logs out, the monitoring is canceled and the memory occupied by the network configuration data is released.
According to the method for assisting the client in carrying out wireless network switching, the client or the server monitors the change of the PC network state, and the client or the server backs up the configuration data of the PC network card. When the wireless network of the client is switched, whether the multiplexing change problem occurs in the manually set DNS configuration item or not is judged through the backed-up data, and recovery is carried out. The problem of DNS access abnormality caused by the multiplexing of the DNS configuration manually set when the PC performs wireless network switching is solved.
