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. The scanning method includes:

Step 102: When the wireless local area network function of the mobile terminal is enabled, the current movement information of the mobile terminal is acquired.

The premise that the mobile terminal uses the default scanning method to search for APs within its preset range to obtain the wireless network is that the wireless local area network function needs to be enabled.

In this embodiment, when the mobile terminal enables the wireless local area network function, it does not immediately scan the available APs around it, but first obtains the movement information of the current mobile terminal. information. The movement information includes movement type information, and the movement type information may include a stationary state and a moving state. Further, the movement state can be divided into screen-on movement and screen-off movement in combination with the screen information; the movement state can be divided into high-speed movement and low-speed movement in combination with the movement speed; the movement state can be divided into flip movement, lift movement, and horizontal movement according to the movement action. and many more.

It should be noted that the movement types of different attributes correspond to one or more movement levels. That is, when the movement type is static state, due to the stability of the static state, the movement level corresponding to the static state can be defined as the first-level movement level; and the mobile state can be divided into movements of various scenarios according to different attributes, and different The movement states of the scene correspond to different movement levels one by one.

Step 104: Determine the scanning mode corresponding to the current movement information according to the preset mapping relationship between the movement level and the scanning mode.

According to the needs of the user, a mapping relationship between the mobility level and the scanning mode is preset and constructed. In the mapping relationship, one mobility level corresponds to one scanning mode. Among them, the scanning mode includes active scanning and passive scanning.

It should be noted that, for the active scanning mode, the mobile terminal will actively send detection signals in sequence on the channels supported by the mobile terminal, so as 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.

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.

According to the acquired mobility information of the current mobile terminal, the current mobility level can be known, and then the scanning mode (active scan or passive scan) corresponding to the mobility level can be acquired according to the mapping relationship, which can prevent the mobile terminal from using only one A fixed scanning mode is used to scan the AP, but a scanning mode suitable for the current mobile terminal is selected to scan the AP according to the current mobility level of the mobile terminal.

Step 106: Scan according to the determined scanning mode to search for a wireless local area network.

According to the scanning mode (active scanning or passive scanning) determined in the mapping relationship, the surrounding APs are scanned to search for available wireless local area networks.

In the above method for scanning the wireless local area network of a mobile terminal, when the wireless local area network function of the mobile terminal is enabled, the current movement information of the mobile terminal is obtained; according to the preset mapping relationship between the movement level and the scanning mode, the scanning corresponding to the current movement information is determined. scanning according to the determined scanning mode to search for the wireless local area network, so that the corresponding scanning mode can be automatically matched according to the current mobility level of the mobile terminal to scan to search for the wireless local area network, which can save power consumption, improve battery life and scanning efficiency, It also reduces radiation.

As shown in FIG. 2 , in one embodiment, determining the scanning mode corresponding to the current movement information according to the preset mapping relationship between the movement level and the scanning mode includes:

Step 202: Parse the current movement information of the mobile terminal to obtain the movement level of the current mobile terminal.

The obtained movement information of the mobile terminal is analyzed, that is, the movement type in the movement information is analyzed, and the corresponding movement level is obtained according to the movement type.

It should be noted that, in the process of obtaining the movement information of the current mobile terminal, the movement type of the current mobile terminal is first obtained, and if the movement type is a stationary state, the movement level corresponding to the stationary state is recorded as the first-level movement level; If the acquired movement type of the current mobile terminal is the mobile state, according to the needs of the user, set the corresponding scene judgment criteria, and obtain the movement levels corresponding to the movement states in different scenarios, wherein the movement levels corresponding to the mobile states are multi-level .

Step 204: According to the current movement level of the mobile terminal, match the corresponding scanning mode in the mapping relationship as the scanning mode corresponding to the current mobile information.

According to the current movement level of the mobile terminal, the preset mapping relationship between the movement level and the scan mode is matched with the scan mode corresponding to the mobile level, and the matched scan mode is used as the target scan mode, and the target scan mode is used to scan the surrounding area. AP to scan.

In one embodiment, before the step of determining the scanning mode corresponding to the current movement information according to the preset mapping relationship between the movement level and the scanning mode, the method further includes constructing a mapping relationship between the movement level and the scanning mode.

Wherein, the movement level can be determined according to the movement type, and the determination of the movement type needs to be determined by an acceleration sensor and/or a gyroscope built in the mobile terminal.

In one embodiment, the obtaining the current movement information of the mobile terminal includes:

Step 302: Acquire the acceleration variation or the angular velocity variation of the mobile terminal within a preset time.

The movement information of the mobile terminal can be detected by the built-in acceleration sensor in the mobile terminal, that is, the movement information of the mobile terminal can be judged by collecting the acceleration variation of the acceleration sensor in the three axes of X, Y and Z within a preset time.

Optionally, the movement information of the mobile terminal can also be detected by the built-in gyroscope in the mobile terminal, that is, the movement is judged by collecting the angular velocity change of the acceleration sensor rotating around the three axes of X, Y, and Z within a preset time. Mobile information of the terminal.

Step 304: Determine the movement type of the mobile terminal according to the acceleration change amount or the angular velocity change amount, and the movement type includes a static state and a moving state; wherein, the static state corresponds to a movement level, and the moving state corresponds to Multiple mobile levels.

When at least one component (acceleration or angular velocity) in the three axes of X, Y and Z changes, it is considered that the mobile terminal has moved. When it changes, the mobile terminal is considered to be in a stationary state.

It should be noted that, if the current movement type of the mobile terminal is a stationary state, the movement level corresponding to the stationary state is defined as a first-level movement level. In the mapping relationship, the first-level mobility level corresponds to the passive scanning mode. For example, when the user fixes the mobile terminal in a certain position to play video, music or black screen standby, no matter whether the mobile terminal is connected to the AP or not, the mobile terminal does not have high requirements on the timeliness of AP scanning. If the active scanning mode is still maintained, the power consumption of the mobile terminal will be increased invisibly, the standby time of the whole machine will be shortened, and additional radiation may be brought to the user; at this time, the active scanning mode can be switched to the passive scanning mode. In order to save power consumption, increase standby time, and reduce radiation.

It should be noted that, by default, the mobile terminal uses active scanning to scan surrounding APs. Active scanning can quickly scan available APs, with good timeliness and fast response; however, the power consumption is high and the radiation is large.

As shown in FIG. 4 , in one embodiment, acquiring the movement information of the current mobile terminal further includes:

Step 402: When the movement type is a movement state, detect the screen state and movement speed of the mobile terminal.

Specifically, when the movement type of the current mobile terminal is a moving state, the screen state of the current terminal is further detected. Wherein, the screen state of the mobile terminal may be a screen-on state and a screen-off state, and a mobile level corresponding to the mobile state may be determined correspondingly according to the screen state of the mobile terminal.

Further, when the movement type of the current mobile terminal is the moving state and the screen state is the bright screen, the movement speed of the current mobile terminal is further detected.

In this embodiment, the moving speed of the mobile terminal can be detected by using the GPS positioning technology, the Beidou positioning technology or the base station positioning technology, and the moving direction of the mobile terminal can be detected by using the gyroscope set in the mobile terminal, but the embodiments of the present application are not limited to this. The moving speed and moving direction of the mobile terminal may be detected in other ways.

Step 404: Acquire the various movement levels according to the screen state and the movement speed.

The mobile level corresponding to the mobile state when the screen is off is positioned as the secondary mobile level; the secondary mobile level corresponds to passive scanning in the mapping relationship.

For example, if the user places the mobile terminal on the bed while sleeping, a turning action of the user causes the mobile terminal to generate accelerations in at least two directions. It is still in the off-screen state, which means that the user is not using the mobile terminal at this time, and the mobile terminal does not have high requirements on the timeliness of AP scanning. The power consumption shortens the standby time of the whole machine; at this time, the active scanning mode can be switched to the passive scanning mode or the passive scanning mode can be maintained to save power consumption, increase the standby time, and reduce radiation.

Further, the obtained moving speed is compared with the preset speed value, and if the currently obtained moving speed is greater than the preset speed value, it is considered that the mobile terminal is in the process of fast moving; when the moving speed is lower than the preset speed value, It is considered that the mobile terminal is in a slow moving process.

The movement level corresponding to the fast moving state when the screen is bright is positioned as the third-level movement level; the third-level movement level corresponds to the passive scan in the mapping relationship.

For example, the mobile terminal in the bright screen state is in the process of rapid movement, and the position of the mobile terminal is constantly and rapidly changing. Even if there is an available AP, it is difficult for the mobile terminal to maintain the connection with the available AP. In this case, the mobile terminal still adopts the active scanning method, which will not only increase the power consumption of the mobile terminal, but also increase the radiation to the user. At this time, the active scanning mode can be switched to the passive scanning mode or the passive scanning mode can be maintained, so as to save power consumption, increase the standby time, and reduce radiation.

The movement level corresponding to the slow movement state when the screen is bright is positioned as the fourth-level movement level; the fourth-level movement level corresponds to the active scan in the mapping relationship.

For example, the mobile terminal in the bright screen state is in the process of slow movement. Although the position of the mobile terminal changes, it changes slowly. In the case of an available AP, the mobile terminal can maintain the connection with the available AP. At this time , the mobile terminal can use the active scanning method, and the active scanning can quickly scan the available APs, with good timeliness and fast response.

Table 1 is the correspondence table of the mapping relationship between mobility type-mobility level and scanning mode

type of movement mobile level scanning method Stationary state first move class passive scan Mobile state (screen off) 2nd move class passive scan Mobile state (quick movement with bright screen) 3rd move class passive scan Movement status (bright screen and slow movement) Level 4 Mobile Active scan

As shown in Table 1, the corresponding relationship between the movement type and the movement level can be clarified, and the mapping relationship between the movement level and the scanning mode is also specified.

It also reduces radiation.

Step 502: Obtain the 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 504: 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 506: 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.

In one embodiment, the wireless local area network scanning method for a mobile terminal further includes the step of switching the active scanning mode to a passive scanning mode when connecting to the wireless local area network in an active scanning mode.

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