Description
Technical Field
The present disclosure relates to the field of wireless communication technologies, and in particular, to a wireless network access method, a wireless network access apparatus, a computer-readable medium, and a wireless communication terminal.
Background
With the rapid development of wireless network technology, people can access the internet through a wireless network in various places, such as markets, stations, hospitals, homes and the like, and great convenience is brought to the life and work of people. WiFi (Wireless Fidelity), which is one of Wireless network technologies, can be networked through radio waves, and has the advantages of high data transmission speed, no limitation of wiring, high security, and the like. For various terminals with WiFi function, such as mobile phones, notebook computers, tablet computers, desktop computers with wireless network cards and the like, the terminals can be connected with the wireless router in a WiFi connection mode within an effective range covered by electric waves of the wireless router, so that networking is realized.
As users demand more and more WiFi usage experience, the demand for WiFi access speed is also increasing. The prior art generally optimizes the WiFi access speed by optimizing the scanning interval, removing "unnecessary" scanning, and optimizing the channel residence time. For example, by optimizing the scan interval, shortening the scan interval may facilitate faster automatic reconnections; or unnecessary scanning can be reduced by prolonging the scanning interval, so as to achieve the purpose of saving power. In the prior art, no clear standard is provided for optimizing the channel residence time, and if the channel residence time is prolonged, the hot spot of the channel can be scanned as much as possible, but the scanning time is increased, and if the automatic reconnection time is prolonged, the power consumption is increased, and the user experience is influenced; otherwise, the mobile phone may not scan for the hot spot. Or, through the DBS (Direct Broadcasting Satellite access) function, 2.4G and 5G frequency bands can be scanned simultaneously, so that the scanning speed is increased, but the chip supporting the DBS function has a too high cost. Therefore, the optimization method provided by the prior art cannot achieve balanced processing of access speed, stability, power consumption and cost.
It is to be noted that the information disclosed in the above background section is only for enhancement of understanding of the background of the present disclosure, and thus may include information that does not constitute prior art known to those of ordinary skill in the art.

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.
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. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
The existing wireless network optimization methods still have some problems and disadvantages, such as: by optimizing the scanning interval, the scanning interval is shortened, which is beneficial to faster automatic reconnection, or unnecessary scanning can be reduced by prolonging the scanning interval, so that the purpose of saving power is achieved, but the situation that the hot spot cannot be scanned may occur. The hot spot of the channel can be scanned as much as possible by prolonging the staying time of the channel, but the scanning time is increased, and the automatic reconnection time is prolonged, so that the power consumption is increased, and the user experience is influenced; otherwise, the mobile phone may not scan for the hot spot. The WiFi connection process cannot be optimized equally.
In view of the above drawbacks and deficiencies of the prior art, the exemplary embodiment provides a wireless network access method, which can be applied to a terminal device capable of wireless connection, such as a mobile phone, a tablet computer, a notebook computer, and a desktop computer configured with a wireless network card. Referring to fig. 1, the wireless network access method may include the steps of:
s101, judging whether a triggering operation for accessing a wireless network exists or not;
s102, when judging that the triggering operation for accessing the wireless network exists, extracting a historical channel list corresponding to the access history of the wireless network of the terminal;
s103, scanning channels in the historical channel list partially or completely to access a wireless network.
In the wireless network access method provided by the present exemplary embodiment, the channel data of the WiFi hotspot connected to the terminal is stored in the historical channel list in advance, and the historical channel list is stored in the terminal device; therefore, when the access to the wireless network is triggered, the wireless network can be accessed only by scanning partial channels according to the historical channel list, so that the connection time is effectively shortened when the wireless network is successfully accessed, and the power consumption of the terminal equipment is further reduced.
Hereinafter, the steps of the wireless network access method in the exemplary embodiment will be described in more detail with reference to the drawings and the embodiments.
Generally, as a commonly used Wireless network technology, a WiFi (Wireless Fidelity) technology may generally include the following steps: (1) scanning (Scanning), including active Scanning and passive Scanning; (2) authentication (Authentication), which generally includes open system Authentication, shared key Authentication, and pre-identity Authentication; (3) association (Association), initiated by the user end, and connecting to the internet when the Association is successful.
As for when the current state of the wireless network management control of the terminal device is off, that is, when the WiFi of the terminal device is in an off state, referring to fig. 2, the wireless network access method may include:
step S101, judging whether a triggering operation for accessing the wireless network exists.
In this example embodiment, the trigger action may be an operation on a WiFi control. Through the triggering action, the terminal equipment can be triggered to start scanning the wireless network in the environment.
For example, for a terminal device such as a mobile phone or a tablet computer, the triggering operation for accessing the wireless network may be a click triggering action on a WiFi control in a shortcut menu (a pull-down menu or a pull-up menu) on a main interface, or a click selection operation on WiFi in a setting interface of the wireless network. Or, for a notebook computer, the triggering action may be a click selection operation of the WiFi option in the network management shortcut in the taskbar through an input device, or a specific operation of the WiFi option in a dedicated network management interface.
Of course, in other exemplary embodiments disclosed, the above-mentioned trigger operation may also be an operation of a WiFi control through an input device in a virtual reality environment. The present disclosure does not specifically limit the specific form of the trigger operation.
And step S112, when judging that the triggering operation for accessing the wireless network exists, identifying the application scene of the triggering operation.
In this example embodiment, when it is determined that the trigger operation exists, the application scenario where the trigger operation is located may be first identified and determined. Specifically, referring to fig. 3, the step S112 may include:
step S1121, identifying the type of the application scene where the trigger operation is located;
step S1122, when the current application scenario is identified as the first connection category, extracting the historical channel list.
For the above-mentioned trigger operation, the specific application scenarios can be classified. For example, a first connection category, which is intended for connecting to already connected hotspots, and a second setting category, which is intended for locating, connecting to new hotspots, or other purposes.
For example, the first connection type may be a click or selection operation on a wireless network management control in a pull-down menu, a pull-up menu, or other shortcut menus displayed in a current interface, when a slide or pull-down operation is performed on a terminal device such as a mobile phone or a tablet computer on a main interface, or when the current interface is an interface of an application program. Or, the wireless network management button can be clicked or selected in the setting interface, and the purpose is only to turn on a wireless network switch and enable the wireless network switch to be automatically connected to the terminal equipment to the connected hot spot.
The second setting category may be an operation of the wireless network management control in an application program interface that requires the use of the location service. For example, operation of WiFi controls on applications of map classes, shared bicycles, shared cars, and the like. Or, the operation may be an operation generated when a new wireless network needs to be connected in the setting interface. For example, clicking or selecting an unconnected hotspot in the setup interface. Of course, in other exemplary embodiments of the present disclosure, the second setting category may also be a situation where an attempt to connect to a connected hotspot fails and jumps to the setting interface.
In an exemplary embodiment of the present disclosure, the historical channel list may be directly extracted only when the application scenario in which the trigger operation is located is identified as the first connection category.
Furthermore, in other exemplary embodiments of the present disclosure, the method may further include:
step S1123, when the current application scenario is identified as the second setting category, performing full channel scanning.
For the trigger operation in the application scene of the second setting category, for example, the trigger operation generated in the application program of the map category, the purpose is to realize the accurate positioning of the terminal device by using the wireless network, and at this time, the scanning of the full channel can be executed.
Based on the above, in this exemplary embodiment, after the identification of the application scenario where the trigger operation is located is completed, in order to determine the current access mode of the wireless network more accurately, the method may further include:
step S113, after the current application scene is identified as the first connection type, determining an area where the current position is located.
Specifically, the step S113 described above may include:
step S1131, judging whether the current position is located in the coverage area of the stored hotspot;
step S1132, when it is determined that the current position is located in the coverage area of the stored hotspot, extracting a historical channel list corresponding to the access history of the terminal wireless network.
After the application scene where the current trigger action is located is identified as the first connection type, the terminal equipment starts to scan all wireless networks related to the current position because the wireless network management control is opened at the moment, and a connectable WiFi list can be generated on the terminal equipment. Meanwhile, according to the connectable WiFi list, whether the current position is located in the coverage range of the stored hotspot can be judged. If the current position is in the coverage area of the stored hotspot, the historical channel list can be extracted.
The historical channel list may include all channel data of hotspots to which the terminal device has connected. For a single hotspot, the frequency of the hotspot channel may be kept in a historical channel list. For an ESS network (extended Service Set), frequency information for multiple channels may be kept in a historical channel list. The historical channel list may be stored in a WiFi configuration storage module (WiFi Config Store). Specifically, a frequency (frequency) member may be configured in a WiFi Configuration class (WiFi Configuration), and a channel value may be stored in the frequency member, and the WiFi Configuration class may be stored in the WiFi Configuration storage module. For example, the channel frequency corresponding to the individual hot spot stored in the historical channel list is 2412; the channel frequencies corresponding to the ESS network include: 412. 2472, 5240, and 5680, etc.
In addition, for the historical channel list, after the historical channel list is extracted, the number of channels in the channel list can be extracted, and the channel residence time of each channel can be configured according to the number of the channels and preset rules.
For example, the dwell time for scanning the channel may be set within a certain time length range. For example
When the number of channels in the historical channel list is less than 3, the configured channel residence time is 140-160 milliseconds. Or when the number of the channels in the historical channel list is 3-6, the configured channel residence time is 100-120 milliseconds. Or when the number of the channels in the historical channel list is 5-10, the configured channel residence time is 100-130 milliseconds, and the like.
The longer the dwell time, the more likely all hotspots of that channel can be scanned. Through the dynamic distribution of the channel residence time according to the number of the channels, the time consumption in the scanning process can be reasonably controlled, so that the time consumption for connecting a wireless network is accurately controlled, and the wireless network connection speed is increased.
In a complex environment, such as an airport, a railway station or a shopping mall, all hotspots of each channel can be scanned to the maximum extent by reasonably prolonging the residence time of the scanning channel, and the condition that the target hotspot cannot be scanned due to short residence time of the scanning channel, so that disconnection or automatic connection is slow is effectively improved.
And step S114, scanning partial or all channels in the historical channel list to access a wireless network.
In this exemplary embodiment, after the history channel list is extracted from the WiFi configuration storage module, the channels in the history channel list may be scanned according to their frequencies. Because the wireless network can be connected only after scanning the appointed partial channels or all the channels in the historical channel list, the connection time of the wireless network can be effectively shortened.
Based on the above, for the history channel list, tag information may also be configured for each channel in the list. For example, it may be a location tag, a signal strength tag, a historical connection duration, etc. Specifically, it may be a place tag, such as home, office, or place a, place B, etc.; specific coordinate information may be used as the label. After extracting the history channel list, the step S114 may further include:
step S1141, sorting each channel in the historical channel list according to the current position and/or the label information of the channel to generate a temporary channel list;
step S1142, scanning according to the channel arrangement order in the temporary channel list.
For example, when the tag information of each channel is coordinate data, a specific distance may be calculated according to the coordinates of the current position and the coordinates of each channel, and then sorting is performed according to the size of the distance to obtain a temporary channel list. Or, when the tag information is historical connection duration, sorting according to the size of the connection duration to obtain a temporary channel list. And the channels are scanned in sequence according to the sequence in the temporary channel list, so that the wireless network can be connected more quickly.
The channels in the historical channel list are sorted according to a certain rule, so that the terminal equipment can preferentially scan the channels with higher connection success probability, the scanning speed is effectively increased, and the time consumption in the scanning process is shortened.
Based on the above, in the present exemplary embodiment, after accessing the wireless network and/or disconnecting from the accessed wireless network, as shown in fig. 4, the method may further include:
step S201, obtaining current channel information to judge whether the current channel is in the historical channel list;
step S202, if it is determined that the current channel is not in the historical channel list, adding the current channel to the historical channel list to update the historical channel list.
For example, when a user connects to or disconnects from a wireless network, for example, a terminal device accesses a new wireless network, or accesses a new channel of an already connected wireless network, for example, after connecting a new single hotspot, the current channel frequency of the hotspot may be stored in the historical channel list. Alternatively, for an ESS hotspot, when the end device connects to a router with channel 2412, after the user successfully connects, if the hotspot of other channels can be scanned in the vicinity of the user, the hotspot is also saved, for example, after the router is scanned to find that there are channels 2472, 5240 and 5680, the above three channels can be added to the historical channel list.
Alternatively, when the terminal device is out of the coverage area of the channel 2412 due to a location change, the WiFi connection is disconnected, but when the terminal device enters the coverage area of the router channel 5560, the terminal device is connected to the 5560 channel, and at this time, the channel 5560 can be added into the historical channel class table. The historical channel list may include: 2412. 2472, 5240, 5680, 5560.
Automatic updating of the historical channel list may be achieved by adding new channel information to the historical channel list.
In addition, in an exemplary embodiment of the present disclosure, when the wireless network management control of the terminal device is in an open state, that is, when the WiFi of the terminal device is in an open state, referring to fig. 5, a wireless network access method is provided, which includes:
step S301, judging whether the current position is located in the coverage area of the stored hotspot;
step S302, when judging that the current position is located in the coverage area of the stored hotspot, extracting a historical channel list corresponding to the access history of the terminal wireless network;
step S303, scanning all or part of the channels in the history channel list to access the wireless network.
Specifically, when the terminal device is in a standby state and the WiFi state is on, the terminal device may scan at regular time according to a preset rule to determine whether the terminal device is currently located in a coverage area of the stored hotspot. And when judging that the current position of the terminal equipment is positioned in the coverage area of the stored hotspot, actively extracting a historical channel list, and partially or completely scanning channels in the historical channel list, thereby realizing the access to a wireless network.
In addition, after the terminal device extracts the historical channel list, the number of channels in the channel list can also be extracted, and the channel residence time of each channel is configured according to the number of channels and preset rules.
In addition, after the wireless network is accessed or the wireless network is accessed and disconnected, the current channel information can be extracted, and when the current channel is judged not to be in the historical channel list, the current channel is added to the historical channel list, so that the historical channel list is automatically updated.
According to the method provided by the embodiment of the disclosure, when a user turns on a WiFi switch in a system interface, or under the condition that the WiFi switch is already turned on, the terminal equipment enters the coverage area of the stored hotspot, scanning is triggered to automatically connect WiFi. The method comprises the steps that channel information of a hotspot or an ESS network connected with a terminal device is stored in a historical channel list in advance; only specific channels in the historical channel list are scanned during scanning, and appropriate channel residence time can be configured according to the number of the channels, so that a scanning result can be obtained more quickly, and network connection can be completed in shorter time. In addition, all hotspots of each channel can be scanned to the maximum extent by configuring proper channel residence time according to the number of the channels, so that the connection stability is effectively improved; and the scanning time can be shortened, so that the power consumption in the scanning process is reduced, and the further optimization of the power consumption is realized.
Specifically, for the time consumption of scanning, the conventional full channel scanning generally needs to scan twenty-three channels, and it takes at least one second or more to complete one full channel scanning according to the minimum scanning channel residence time, and the time consumed by switching between channels is calculated, so the time of channel scanning is longer. However, the hot spot to which the user terminal needs to connect is often only a few channels. Compared with the conventional full channel scanning which needs to scan twenty-three channels, the scheme of the embodiment of the disclosure can shorten the time consumption of the scanning process to be within hundreds of milliseconds. Because the automatic hot spot connection speed depends on the return of the scanning result, the automatic hot spot connection speed is effectively improved on the premise of effectively shortening the time consumption of the scanning process. The method and the device can scan the hot spot more quickly, accurately and more energy-consumptively and complete the access of the wireless network, and improve the user experience.
In addition, for the power consumption of the terminal device, when the mobile phone scans, the current is about 200mA (taking the sdm670 platform as an example), and the duration is determined by the scanning time.
In addition, in a complex environment such as an airport, a train station, and the like, the residence time of a scanning channel is short, and a target hotspot cannot be scanned frequently, so that disconnection or automatic connection is slow. According to the embodiment of the disclosure, by prolonging the residence time of the scanning channel, all hotspots of the channel can be scanned as much as possible, so that the situation of slow hotspot connection speed can be effectively improved.
It is to be noted that the above-mentioned figures are only schematic illustrations of the processes involved in the method according to an exemplary embodiment of the invention, and are not intended to be limiting. It will be readily understood that the processes shown in the above figures are not intended to indicate or limit the chronological order of the processes. In addition, it is also readily understood that these processes may be performed synchronously or asynchronously, e.g., in multiple modules.
Further, referring to fig. 6, in an embodiment of the present example, a wireless network access apparatus 60 is further provided, including: a trigger detection module 601, a first list extraction module 602, and an access execution module 603. Wherein:

the application scenario identification module may be configured to identify a category of an application scenario in which the trigger operation is located.
The first connection category execution module may be configured to extract the historical channel list when the current application scenario is identified as the first connection category.
