detailed description

Usually, scanning is frequent, and the information of surrounding access points can be obtained more quickly. Wi-Fi scanning is slow, and the acquisition is slow. However, when the user position is not moving, Wi- is frequently performed. Fi scanning increases the power consumption of the mobile terminal. The embodiments of the present invention provide a wireless fidelity Wi-Fi scanning method and related products, which can avoid frequent Wi-Fi scanning, thereby reducing power consumption of the mobile terminal.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The terms "first", "second", "third", and "fourth" and the like in the specification and claims of the present invention are used to distinguish different objects, and are not intended to describe a specific order. . Furthermore, the terms "comprises" and "comprising" and "comprising" are intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or device that comprises a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units not listed, or alternatively Other steps or units inherent to these processes, methods, products or equipment.

References to "an embodiment" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of the invention. The appearances of the phrases in various places in the specification are not necessarily referring to the same embodiments, and are not exclusive or alternative embodiments that are mutually exclusive. Those skilled in the art will understand and implicitly understand that the embodiments described herein can be combined with other embodiments.

The mobile terminal described in the embodiments of the present invention may include a smart phone (such as an Android mobile phone, an iOS mobile phone, a Windows Phone mobile phone, etc.), a tablet computer, a palmtop computer, a notebook computer, a mobile Internet device (MID, Mobile Internet Devices), or a wearable device. The foregoing is merely an example, and not an exhaustive, including but not limited to the above-described mobile terminal.

It should be noted that, in general, when the mobile terminal is in the Wi-Fi connection state or the Wi-Fi disconnection state, the Wi-Fi chip is activated at a certain frequency (fixed frequency). Wi-Fi scanning, the more frequent Wi-Fi scanning, the faster access to surrounding access points and access point information changes, Wi-Fi scanning slow, it will get slow, but the user position has not been moving At the same time, frequent Wi-Fi scanning is not necessary. Under the premise of not moving, the surrounding access points and access point information are relatively fixed in a short time, and the scanning frequency of Wi-Fi scanning can be appropriately reduced.

FIG. 1 is a schematic flowchart diagram of a first embodiment of a wireless fidelity Wi-Fi scanning method according to an embodiment of the present invention. The wireless fidelity Wi-Fi scanning method described in this embodiment includes the following steps:

101. Detect whether the location of the mobile terminal changes.

Optionally, in step 101, detecting whether the location of the mobile terminal changes includes:

Obtaining whether a distance between the current location and the last recorded location is greater than a first preset threshold, and a distance between the current location and the last recorded location is greater than the first preset threshold, confirming the The location of the mobile terminal has changed.

The mobile terminal can obtain the current location through the Wi-Fi positioning technology, or obtain the current location through a Global Positioning System (GPS). The first preset threshold may be set by the system by default or by the user, for example, 5 meters, 10 meters, 11.5 meters, 20 meters, and the like. The last recorded position is the position of the terminal determined when the positioning was last performed, and "last time" can be understood as the closest to the current time. When the distance between the current location and the last recorded location is greater than the first predetermined threshold, it is determined that the location of the mobile terminal has changed. When the distance between the current location and the last recorded location is less than or equal to the first predetermined threshold, it is determined that the location of the mobile terminal has not changed. For example, if the first preset threshold is 10 meters, if the distance between the current position and the last recorded position is 5 meters, the position of the mobile terminal is not changed, if the current position is between the last recorded position and the last recorded position. The distance is 11 meters, indicating that the location of the mobile terminal has changed.

Detecting whether the Wi-Fi signal strength change value of the mobile terminal is greater than a second preset threshold, and determining, by the mobile terminal, a Wi-Fi signal strength change value that is greater than the second preset threshold, confirming the location of the mobile terminal Has changed.

In the process of moving the mobile terminal, the Wi-Fi signal strength also changes. Therefore, whether the location of the mobile terminal changes can be determined by detecting the change value of the Wi-Fi signal strength. The second pre- The threshold can be set by the system default or by the user, for example, 5 decibel (dB), 10 dB, 11.5 dB, 20 dB, and the like. The Wi-Fi signal strength change value of the mobile terminal is greater than the second preset threshold, and it is confirmed that the location of the mobile terminal has changed. The Wi-Fi signal strength change value of the mobile terminal is less than or equal to the second preset threshold, and it is confirmed that the location of the mobile terminal has changed. For example, if the mobile terminal detects that the change of the signal strength of the access point A exceeds the second preset threshold within the coverage of the access point A, the mobile terminal may change its location and may leave. The access point A is within the coverage. For example, if the second preset threshold is 5 dB, if the Wi-Fi signal strength change value is 3 dB, the position of the mobile terminal is unchanged. If the Wi-Fi signal strength change value is 6 dB, the location of the mobile terminal has changed. .

Detecting whether the vibration frequency of the mobile terminal is greater than a preset frequency threshold, and confirming that the location of the mobile terminal has changed when the vibration frequency of the mobile terminal is greater than the preset frequency threshold.

Wherein, in the process of moving the mobile terminal, the vibration frequency of the mobile terminal also changes, and thus, whether the position of the mobile terminal changes can be determined by detecting the vibration frequency. The above preset frequency threshold is set by the system default or by the user. When the vibration frequency of the mobile terminal is greater than a preset frequency threshold, it is confirmed that the position of the mobile terminal has changed. When the vibration frequency of the mobile terminal is less than or equal to the preset frequency threshold, it is confirmed that the position of the mobile terminal does not change. Assuming that the preset frequency threshold is 50 Hz, if the vibration frequency of the current mobile terminal is 5 Hz, the position of the mobile terminal is unchanged. If the vibration frequency of the current mobile terminal is 51 Hz, the position of the mobile terminal has changed.

A), obtain the current Wi-Fi list of the current Wi-Fi scan;

B) determining whether the similarity between the current Wi-Fi list and the last Wi-Fi list is less than a preset similarity between the current Wi-Fi list and the last Wi-Fi list When the similarity is less than the preset similarity, it is confirmed that the location of the mobile terminal has changed. As shown in FIG. 1a, FIG. 1a is a schematic diagram of a Wi-Fi list.

The mobile terminal may generate a scan record, that is, a Wi-Fi list, after each Wi-Fi scan, and the Wi-Fi list may include multiple access points and their corresponding access point information. The above preset similarity can be set by the system default or by the user. In step B, the mobile terminal can obtain the last Wi-Fi list, and the last Wi-Fi list can be understood as the Wi-Fi obtained by the Wi-Fi scan closest to the current time. List, assuming that the mobile terminal is fixed at one location, the Wi-Fi list obtained by each scan is relatively stable. For example, the mobile terminal is in the A position, and its Wi-Fi list includes access points a1, a2, a3, and A4. If the mobile terminal is always in the A location, the access points included in the Wi-Fi list may still be a1, a2, a3, and a4. Of course, the access point included in the Wi-Fi list may still be a1. , a2 and a3 (for example: the access point corresponding to a4 is closed).

Optionally, the similarity may be determined as the number of access points in the Wi-Fi list that are not present in the last Wi-Fi list, and the access point a1, a2 is included in the last Wi-Fi list. A3 and a4, the current Wi-Fi list includes access points a1, a2, and a5, and the number of access points that do not exist in the last Wi-Fi list is 2 (ie, a3 and a4), and the similarity is 2. Assuming that the preset similarity is 2, it is confirmed that the position of the mobile terminal has not changed. Assuming that the preset similarity is 3, it is confirmed that the position of the mobile terminal has changed.

Optionally, the similarity may be determined as the number of access points that exist in the last Wi-Fi list and the total number of access points in the last Wi-Fi list with the access point of the current Wi-Fi list. Ratio, assuming that the last Wi-Fi list contains access points a1, a2, a3, and a4, and the current Wi-Fi list contains access points a1, a2, and a5, which exist in the last Wi-Fi list. If the number of ingress points is 2 (ie, a1 and a2), the similarity is 50%. If the preset similarity is 50%, confirm that the position of the mobile terminal has not changed. Assuming the preset similarity is 75%, confirm the movement. The location of the terminal has changed.

It is detected whether the Wi-Fi connection status of the mobile terminal changes, and when the Wi-Fi connection status of the mobile terminal changes, it is confirmed that the location of the mobile terminal has changed.

Wherein, when the mobile terminal moves, the signal strength of the connected access point also changes constantly, and when the signal strength of the connected access point changes below a certain threshold, the mobile terminal may disconnect and The connection between the access points, as such, can reflect to some extent that the location of the mobile terminal has changed. Of course, the mobile terminal accesses the X access point before, and the current access point is the Y access point, indicating that the location of the mobile terminal has changed. That is, when the disconnected Wi-Fi connection state of the mobile terminal is detected, or, when the access point accessed by the mobile terminal changes (for example, when the X access point changes to the Y access point), the mobile terminal is illustrated. The location has changed. If the mobile terminal is always within the coverage of the X access point, it can be stated that the location of the mobile terminal has not changed.

102. Perform Wi-Fi scanning according to the first scanning frequency when the location of the mobile terminal changes.

Wherein, the location of the mobile terminal is changing, then the mobile terminal may be moving, so, according to the A scan frequency for Wi-Fi scanning. When the mobile terminal is moving, the connected Wi-Fi network is at risk of disconnection at any time, so scanning is required, so that the connectable access point can be quickly found, and the connectable access point is scanned at the mobile terminal. The access point can be accessed, so as to ensure that the mobile terminal can quickly access the Wi-Fi network.

103. Perform Wi-Fi scanning according to a second scanning frequency when the location of the mobile terminal does not change, where the second scanning frequency is smaller than the first scanning frequency.

Wherein, if the location of the mobile terminal does not change, the scanning frequency of the Wi-Fi chip can be appropriately reduced. At this time, the scanning frequency of the Wi-Fi chip can be set to the second scanning frequency. Of course, the second scanning frequency can be smaller than the second scanning frequency. A scanning frequency is compared with a Wi-Fi scan performed by the Wi-Fi chip according to the first scanning frequency. If the second scanning frequency is used for Wi-Fi scanning, less power consumption can be consumed, due to the number of scans per unit time. Less, the power consumption of mobile terminals is also less. In this way, compared with the prior art, the Wi-Fi scanning is compared according to the fixed frequency. In the embodiment of the present invention, the power consumption of the mobile terminal can be reduced to some extent. The power consumption of the mobile terminal is reduced, and its endurance is also improved.

For example, the location of the mobile terminal is unchanged, and thus, Wi-Fi scanning can be performed at the second scanning frequency. If the location of the mobile terminal is unchanged, the stability of the connection to the Wi-Fi network is related to the stability of the access point itself. As long as the access point is stable, the Wi-Fi network of the mobile terminal is also stable. In this case, There is no need to perform Wi-Fi scanning at a higher Wi-Fi scanning frequency (for example, the first scanning frequency), and only need to perform Wi-Fi scanning according to the reduced Wi-Fi scanning frequency (for example, the second scanning frequency). For example, if the mobile terminal does not use the mobile terminal for a period of time, the mobile terminal may disconnect the connection state with the Wi-Fi network, and after the disconnection, scan according to the second scanning frequency, when scanning to the connectable connection At the point of entry, the access point can be accessed. As such, in the case where the location of the mobile terminal is not changed, power consumption due to Wi-Fi scanning by the Wi-Fi chip can be reduced.

Optionally, performing the Wi-Fi scan according to the second scanning frequency, including:

If the location of the mobile terminal does not change within a preset length of time, and the mobile terminal is always in a dormant state, Wi-Fi is turned off.

The preset time length may be set by the system default or by the user, such as 10 seconds, 1 minute, 68 seconds, 105.3 seconds, and the like.

It can be seen that, by using the embodiment of the present invention, whether the location of the mobile terminal changes is detected, and when the location of the mobile terminal changes, the Wi-Fi scan is performed according to the first scanning frequency, and the location of the mobile terminal does not change. In the case of the second scanning frequency, the Wi-Fi scanning is performed, wherein the second scanning frequency is smaller than the first scanning frequency. Therefore, when the position of the mobile terminal changes and does not change, the scanning is performed according to different scanning frequencies, and thus, the power consumption of the mobile terminal can be reduced.

With reference to FIG. 2, it is a schematic flowchart of a second embodiment of a wireless fidelity Wi-Fi scanning method according to an embodiment of the present invention. The wireless fidelity Wi-Fi scanning method described in this embodiment includes the following steps:

201. Detect whether the power of the mobile terminal is lower than a third preset threshold.

The third preset threshold may be set by the system default or by the user, for example, 30%, 50%, 75%, and the like.

Optionally, when the power of the mobile terminal is greater than or equal to the third preset threshold, the step after step 201 may not be performed. In this case, the power of the mobile terminal may be considered to be sufficient, and the Wi-Fi chip may follow the normal frequency sweep. The frequency is scanned by Wi-Fi.

202. When the power of the mobile terminal is lower than the third preset threshold, determine whether the duration of the mobile terminal in the sleep state is greater than a fourth preset threshold.

The fourth preset threshold may be set by the system default or by the user, for example, 30 seconds, 1 minute, 5 minutes, half an hour, and the like. When the duration in which the mobile terminal is in the sleep state is greater than the fourth preset threshold, it indicates that the user does not operate the mobile terminal.

Optionally, when the mobile terminal determines that the duration of the mobile terminal in the dormant state is less than or equal to the fourth preset threshold, the user is in use of the mobile terminal. In this case, the Wi-Fi network connection status may need to be maintained at any time, and the mobile terminal can continue to perform Wi-Fi scanning according to the first scanning frequency to ensure that the Wi-Fi network can be quickly connected even if the line is dropped. Into the network.

203. When the duration of the mobile terminal being in a sleep state is greater than the fourth preset threshold, detecting whether the location of the mobile terminal changes.

204. Perform Wi-Fi scanning according to the first scanning frequency when the location of the mobile terminal changes.

205. Perform Wi-Fi scanning according to a second scanning frequency when the location of the mobile terminal does not change, where the second scanning frequency is less than the first scanning frequency.

If the duration of the mobile terminal in the dormant state is greater than the fourth preset threshold, the user may not use the mobile terminal, and the location of the mobile terminal may be detected. If the location changes, Then, the mobile terminal may be moving, then the Wi-Fi scan may be performed according to the first scan frequency, and if the location is not changed, the Wi-Fi scan may be performed according to the second scan frequency.

For example, in general, the Wi-Fi chip of the mobile terminal has a fixed scanning frequency, and the normal scanning frequency of the Wi-Fi is F1. If the power is saved, the scanning frequency of the Wi-Fi chip can be set to F2. Among them, F2 is smaller than F1. If the user actively views the current access point information (the user is operating the mobile terminal) on the Wi-Fi function setting interface or other software interface of the mobile terminal, the power saving policy may be temporarily stopped according to the normal Wi-Fi scanning policy (ie, scanning). The frequency F1) is scanned to ensure that when the user actively views the mobile terminal, the mobile terminal can perform Wi-Fi scanning in time to obtain the access point information around the mobile terminal in time, that is, at least on the display interface of the mobile terminal can be displayed by at least A Wi-Fi list generated by an access point information. If the user does not actively take the mobile terminal to obtain surrounding access point information, the Wi-Fi chip may be in an automatic scanning state. For example, the mobile terminal can obtain the real-time location of the mobile terminal and record. When the mobile terminal performs Wi-Fi scanning, the current location is compared with the previous location record. If the location is changed, the Wi can be performed according to the scanning frequency F1. -Fi scan, of course, can also update the location information of the mobile terminal. If the location of the mobile terminal does not change, the Wi-Fi scan can be performed according to the scan frequency F2. In this case, the number of scans per unit time is reduced with respect to the scan frequency F1, and thus the mobile terminal can be reduced. The power consumption is adjusted, so that the Wi-Fi scanning strategy can be adjusted through the change of the location information of the mobile terminal, thereby reducing the power consumption of the mobile terminal.

It can be seen that, when the current power of the mobile terminal is lower than the preset threshold, the time for detecting whether the mobile terminal is in the sleep state is greater than the fourth preset threshold, and the time when the mobile terminal is in the sleep state is greater than the first time. The four preset thresholds may detect whether the location of the mobile terminal changes. When the location of the mobile terminal changes, the Wi-Fi scan is performed according to the first scanning frequency, and when the location of the mobile terminal does not change, the Wi is performed according to the second scanning frequency. - Fi scan, wherein the second scan frequency is less than the first scan frequency. Therefore, when the position of the mobile terminal changes and does not change, according to different scanning frequencies The rate is scanned, thus reducing the power consumption of the mobile terminal. In particular, if the location of the mobile terminal is not changed, Wi-Fi scanning can be performed at a lower scanning frequency, which can improve the standby capability of the mobile terminal.

Consistent to the above, the following is an apparatus for implementing the above-described wireless fidelity Wi-Fi scanning method, as follows:
