Detailed ways

In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

As shown in FIG. 1 , an embodiment of the present application provides a method for scanning a wireless local area network of a mobile terminal, and the method for scanning a wireless local area network for a mobile terminal includes:

Step 102: when the wireless local area network function of the mobile terminal is enabled, determine whether the current mobile terminal is in a locked screen state.

If the mobile terminal needs to access the wireless local area network, it needs to discover a nearby and accessible network access device, such as a wireless access point (Access Point, AP), and scan, authenticate and associate with the network access device before it can Access the wireless LAN. The prerequisite for scanning, authenticating and associating the mobile terminal with the network access device is that the mobile terminal needs to enable the wireless local area network.

When the wireless local area network function of the mobile terminal is turned on, it is necessary to determine whether the current mobile terminal is in a locked screen state. Specifically, when the screen-off broadcast of the mobile terminal is received, the screen saver manager provided externally by the system screen-locking mechanism of the mobile terminal operating system can be used to determine whether the current mobile has a screen-locked state, that is, whether it is in a screen-locked state. The lock screen state includes a screen-off lock-screen state and a screen-on-screen lock state.

For example, taking the Android system as the operating system as an example, when receiving the screen-off broadcast of the mobile terminal, the screen saver manager provided by the system screen lock mechanism of the operating system can be used to determine whether the screen is in the locked state. If the screen status is displayed, the next process is performed, that is, step S104 is executed. If it is not in the locked screen state but in the unlocked and bright screen state, the next process is performed, that is, step S106 is performed.

Step 104: Scan the wireless local area network in a passive scanning mode.

When the mobile terminal is in a screen-locked state, where the screen-locked state includes a screen-on-screen lock state and a screen-off screen lock state, the default active scanning mode of the mobile terminal is switched to a passive scanning mode, and the passive scanning mode is used to scan nearby, An accessible network access device, such as a wireless access point (Access Point, AP). That is, when the mobile terminal is in the locked screen state, regardless of whether the mobile terminal is connected to a network access device (for example, an AP), the user's urgency requirement for the wireless local area network when the screen is locked is not as high as when the screen is unlocked and bright. If at this time, the default active scanning mode is still maintained, and high-power radio frequency signals are periodically transmitted to scan for nearby and accessible network access devices, it will invisibly increase the power consumption of the mobile terminal and shorten the whole machine. The standby time does not really improve the additional power consumption of the user experience, but shortens the standby time. After switching the active scanning mode to the passive scanning mode, it may take a little longer to connect to the available network access devices. However, at this time, the mobile terminal is in the locked screen state, and the user basically cannot perceive the time consumption, which does not affect the user experience. At the same time, it can save power consumption, improve battery life, and reduce radiation.

It should be noted that, for the passive scanning mode, the mobile terminal does not actively send a probe request frame, but passively receives a beacon frame (Beacon) periodically sent by the wireless access point to discover the network. The beacon frame includes information such as the service set identifier of the wireless access point AP, the supported rate, the MAC address of the wireless access point, the supported authentication method, the encryption algorithm, the beacon frame sending interval, and the channel used. For example, the default period for the wireless access point to send the beacon frame is 100ms, that is, the wireless access point broadcasts and sends the beacon frame every 100ms. The STA learns the surrounding wireless network by listening to the beacon frame on each channel it supports.

For the active scanning mode, the mobile terminal will actively send detection signals in sequence on the channels supported by it to detect the surrounding wireless networks. The probe signal sent by the mobile terminal is called a probe request frame (Probe Request), and a network signal is obtained by receiving a probe response frame (Probe Response). The probe request frame can be further divided into two categories, one is an unspecified service set identifier (Service Set Identifier, SSID), and the other is a specified service set identifier. If the service set identifier is not specified in the probe request frame, it means that the probe request wants to obtain all available wireless network signals around, and all wireless access points that receive the broadcast probe request frame will respond to the mobile terminal. If the service set ID is specified in the probe request frame, it means that the mobile terminal only wants to find a specific service set ID, and does not need other wireless networks other than the specified service set ID. After the wireless access point receives the probe request frame, it will respond to the mobile terminal only when it finds that the service set ID in the probe request frame is the same as its own service set ID.

Step 106: Scan the wireless local area network according to the first preset scanning strategy.

When the mobile terminal is in the unlocked and bright screen state, the wireless local area network can be scanned according to the first preset scanning strategy. Among them, the first preset scanning strategy can be understood as that the corresponding scanning mode (active scanning or passive scanning) can be set according to different application scenarios when the screen is unlocked and bright to scan for nearby and accessible network access equipment.

For example, the corresponding scanning mode can be automatically matched to scan for nearby and accessible network access devices according to application scenarios such as the moving speed of the mobile terminal when the screen is locked and bright, and applications that need to be connected to the wireless network.

In the above-mentioned mobile terminal wireless local area network scanning method, when the wireless local area network function of the mobile terminal is enabled, it is judged whether the current mobile terminal is in a locked screen state; if it is in a locked screen state, the default active scanning mode of the mobile terminal is switched to passive scanning mode to scan wireless Compared with the default active scanning mode, the local area network can save power consumption, improve battery life, and reduce radiation; if it is in the unlocked and bright screen state, the wireless local area network is scanned according to the first preset scanning strategy, that is, it can flexibly and automatically match the corresponding Scanning mode to scan for nearby and accessible network access devices to scan wireless local area networks to improve user experience.

As shown in FIG. 2, in one embodiment, the scanning of the wireless local area network according to the first preset scanning strategy includes:

Step 202: Detect the current moving speed of the mobile terminal.

In this embodiment, the moving speed of the mobile terminal can be detected through GPS positioning technology, Beidou positioning technology or base station positioning technology, and the moving direction of the mobile terminal can also be detected through a gyroscope set in the mobile terminal, but the embodiment of the present application is not limited to Therefore, other methods may also be used to detect the moving speed and moving direction of the mobile terminal.

Step 204: When the moving speed is greater than or equal to the first preset speed, use a passive scanning mode to scan the wireless local area network.

Wherein, the first preset speed may be the riding speed of the bicycle, for example, it may be 15-20km/h (kilometers per hour), and of course, it may be set as the normal driving speed of the motor vehicle, for example, it may be 30-20km/h (kilometers per hour). 100km/h.

When the moving speed of the mobile terminal is greater than the first preset speed, it is considered that the mobile terminal is in the process of rapid movement, that is, the position of the mobile terminal is constantly and rapidly changing. Even if there is an accessible network access device (such as a wireless access point) at the current location, it is difficult for the mobile terminal to maintain a connection with the available network access device. If the mobile terminal still adopts the active scanning mode at this time, it will not only increase the power consumption of the mobile terminal, but also increase the radiation to the user. Therefore, the scanning mode of the fast moving mobile terminal in the unlocked and bright screen state can be set to the passive scanning mode, so as to save power consumption, increase the standby time, and reduce radiation at the same time.

It should be noted that, the value of the first preset speed may be set according to the needs of the user, which is not further limited here.

Step 206: When the moving speed is less than or equal to the second preset speed, scan the wireless local area network according to the second preset scanning strategy.

The second preset speed may be the walking speed at which the user takes a walk, for example, may be 3-6 km/h (kilometers per hour).

When the moving speed of the mobile terminal is less than or equal to the second preset speed, it is considered that the mobile terminal is in the process of slow moving, and although the position of the mobile terminal changes, the change is relatively slow. When an accessible network access device (eg, a wireless access point) exists, the mobile terminal can maintain a connection with the available network access device. At this time, the mobile terminal may scan for nearby and accessible network access devices using the second preset scanning strategy.

Further, as shown in FIG. 3, in one embodiment, scanning the wireless local area network according to the second preset scanning strategy includes:

Step 302: Detect whether a wireless scanning request sent by an application is received, where the wireless scanning request carries the history attribute of the application.

When the mobile terminal is in the unlocked and bright-screen state, and the current moving speed of the mobile terminal is less than or equal to the second preset speed, when there is an accessible network access device (such as a wireless access point), the mobile terminal can maintain communication with the available network Access device connection. When the application program in the foreground or background of the mobile terminal needs to access the wireless local area network, it needs to send a wireless scanning request to the operating system of the mobile terminal. After the operating system responds to the wireless scanning request, the application program is allowed to access the wireless local area network. Wireless LAN.

Specifically, the wireless scan request carries the historical attribute of the application, wherein the historical attribute of the application includes the historical duration and historical access frequency of the application accessing the wireless local area network within a preset period. The preset period may be 24 hours, that is, from 00:00 in the morning to 24:00:00 in the middle of the night, with each day as a period.

If the mobile terminal receives the wireless scanning request sent by the application, the next step is performed, that is, step S304 is executed.

Step 304: Determine the current scan mode of the mobile terminal according to the mapping relationship between the preset history attribute and the scan mode. Wherein, the scanning mode includes active scanning and passive scanning.

When the historical duration of the application accessing the wireless local area network within the preset period is greater than the preset duration, in the mapping relationship table, the scanning mode corresponding to the historical attribute is set to the active scanning mode; otherwise, in the mapping relationship In the table, the scanning mode corresponding to the historical attribute is set to passive scanning mode.

Correspondingly, when the historical frequency of the application accessing the wireless local area network in the preset period is greater than the preset frequency, then in the mapping relationship table, the scanning mode corresponding to the historical attribute is set to the active scanning mode; In the mapping relationship table, the scanning mode corresponding to the historical attribute is set as the passive scanning mode.

Table 1 is the mapping relationship between historical attributes and scanning methods.

historical properties scanning method The historical duration is longer than the preset duration Active scan The historical duration is less than the preset duration passive scan The historical frequency is greater than the preset frequency Active scan The historical frequency is less than the preset frequency passive scan

According to the historical attribute carried in the wireless scanning request, the scanning mode (active scanning or passive scanning) corresponding to the historical attribute can be obtained according to the mapping relationship between the historical attribute and the scanning mode as shown in Table 1.

Step 306: Scan the wireless local area network according to the determined scan mode.

For example, if the application is the most frequently used chat interaction program by the user, it can be determined that the scanning mode corresponding to the historical attribute of the application is the active scanning mode. At this time, the mobile terminal switches to the active scanning mode, which can quickly Scan to the available wireless LAN, with good timeliness and fast response. Correspondingly, if the scanning mode corresponding to the history attribute of the application is the passive scanning mode, passive scanning is used to scan the wireless local area network, so as to save power consumption, increase the standby time, and reduce radiation.

In this embodiment, the corresponding scanning mode can be determined in the mapping relationship according to the historical attribute of the application in real time, and the wireless network can be scanned by the matching scanning mode according to different historical attributes. Scanning efficiency, timeliness, and fast response; passive scanning mode can save power consumption, increase standby time, and reduce radiation.

Optionally, as shown in FIG. 4 , in one embodiment, scanning the wireless local area network according to the second preset scanning strategy includes:

Step 402: Dynamically adjust the scanning frequency of the active scanning mode according to the moving speed.

That is, the second preset scanning strategy can be understood as an active scanning mode, and in the process of adopting the active scanning, the scanning frequency of the active scanning mode can be dynamically adjusted according to the moving speed of the mobile terminal.

For example, if the current moving speed of the mobile terminal is in the range of 0-1 km/h, it can be understood that the current moving speed of the mobile terminal is very slow and close to a stationary state. The time interval of the request frame can detect the surrounding wireless network faster.

It should be noted that when the mobile terminal in the unlocked and bright screen state is moving slowly, the smaller the moving speed, the higher the scanning frequency of the active scanning mode, and the moving speed is inversely proportional to the scanning frequency.

In one embodiment, after step 402: dynamically adjusting the scanning frequency of the active scanning mode according to the moving speed, it may further include:

Step 404: When using the active scanning mode to access the wireless local area network, switch the active scanning mode to a passive scanning mode.

That is, when the mobile terminal scans a nearby and accessible wireless local area network through the active scanning mode, and the mobile terminal accesses the wireless local area network, the active scanning mode currently used by the mobile terminal can be switched to the passive scanning mode. When the mobile terminal is connected to the network access device, the user's requirement for real-time searching of other network access devices is not high. At this time, switching the active scanning mode to the passive scanning mode can save power consumption and increase battery life. , while reducing radiation.

As shown in FIG. 5 , in one embodiment, the method for scanning a wireless local area network of a mobile terminal includes:

Step 502: when the wireless local area network function of the mobile terminal is enabled, determine whether the current mobile terminal is in a locked screen state;

Step 504: If it is in a screen-locked state, determine whether the duration of the mobile terminal being in the screen-locked and screen-off state exceeds a preset time.

It can be understood that the preset time is the buffering time, which can prevent the scanning mode from being switched back and forth due to accidentally turning off the screen or quickly turning on the screen after turning off the screen, which increases the time for scanning the wireless local area network.

If the duration of the screen-locking and screen-off state exceeds the preset time, step 506 is executed: the wireless local area network is scanned in a passive scanning mode.

In one embodiment, scanning the wireless local area network includes:

Step 602: Obtain location information of the current mobile terminal.

The location information of the mobile terminal can be detected through GPS positioning technology, Beidou positioning technology or base station positioning technology. In this embodiment, the location information of the current mobile terminal is obtained by using the base station positioning technology, and it is not necessary to actively turn on the GPS positioning, so as to reduce the power consumption of using the GPS positioning.

Step 604: Acquire a preset hotspot database matching the location information.

Wherein, the preset hotspot database stores a plurality of hotspots that can cover the current location area. That is, the coverage of the hotspots stored in the preset hotspot database includes the current location area where the mobile terminal is located.

It should be noted that the hotspots in the preset hotspot database may be commonly used hotspots, or may be secure hotspots that the mobile terminal used to connect to.

Step 606: Select a corresponding hotspot from the preset hotspot database to scan.

The database stores the stability information of the connection between each hotspot and the mobile terminal. The number of hotspots in the preset database may be arbitrary, for example, there may be one, two or more, and when the number of hotspots is one, the hotspot may be directly scanned preferentially. When the number of hotspots is multiple, scanning can be performed according to the stability information of the connection between each hotspot and the mobile terminal.

In this embodiment, the mobile terminal may be able to preferentially scan the WiFi hotspots with high stability in the preset hotspot database as much as possible, which can improve the scanning accuracy, avoid the mobile terminal from blindly scanning and connecting all WiFi hotspots, and reduce the number of WiFi hotspots. The extra power consumption improves the user experience.
