technical field

The present invention relates to the field of communications, in particular to a method and device for scanning a Wireless Fidelity (abbreviated as WIFI) access point.

When the user turns on the WIFI module, the first action of the WIFI module is to scan the access point, and present the scanning result to the user, and the user selects an access point to connect. After the user activates the WIFI module, a scan of the access point is performed, and then the next scan is performed at a fixed time interval. For example, an access point scan is performed every 5 seconds until the user turns off the WIFI module.

Detailed ways

Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

The present embodiment provides a WIFI access point scanning method. FIG. 2 is a flowchart of the WIFI access point scanning method according to an embodiment of the present invention. As shown in FIG. 2 , the method includes the following steps:

Step S202, determining the time interval for scanning the WIFI access point according to the state of the mobile terminal;

Step S204, scan for WIFI access points according to the determined time interval.

In this embodiment, through the above steps, the time interval for scanning WIFI access points is determined according to the state of the mobile terminal, and scanning is performed according to the time interval, so that the time interval for scanning WIFI access points can be adjusted along with the state of the mobile terminal. change, so that the scanning time interval can be automatically adjusted, which solves the problem caused by the mobile terminal WIFI access point scanning according to a fixed time interval in the related art, and provides a solution for not affecting the use of the WIFI function and reducing the scanning frequency of the WIFI access point. Possibly, it can further reduce the power consumption of the battery of the mobile terminal by the WIFI function, prolong the standby time of the mobile terminal, and improve user experience.

For step S204, there can be multiple ways to scan for WIFI access points according to a certain time interval, for example, after a scan, a timer set with the time interval can be opened, and when the timer expires, the next scan is performed . Alternatively, other methods may also be used to scan for WIFI access points according to the above-mentioned determined time intervals, which will not be repeated here.

As a preferred implementation manner, the time interval for scanning the WIFI access point can be determined according to the duration of WIFI function activation and/or the battery level of the mobile terminal. For example, the time interval between this scan and the next scan can be increased as the time for activating the WIFI function increases and/or the battery power of the mobile terminal decreases. In this way, the time interval after each scan after the WIFI function is activated can be gradually increased, so that the consumption of the battery power of the mobile terminal by the WIFI function can be quickly reduced, and the standby time of the mobile terminal can be further extended.

For example, the time interval can be linearly increased with the duration of WIFI function activation, or the increase of the time is inversely proportional to the battery power as the battery power of the mobile terminal decreases, or the time interval of WIFI function activation and the battery power of the mobile terminal can be integrated Considerations are made to get this time interval. Preferably, the time interval between this scan and the next scan can also be increased in the form of an exponential function.

For example, the time interval between this scan and the next scan can be y=a ^x , where a is the base of the exponential function and a is greater than 1, and x increases with the time of activating the WIFI function, preferably , in the case of comprehensively considering the duration of WIFI function activation and the battery power of the mobile terminal to obtain the time interval, the value of a may also be determined according to the battery power of the mobile terminal; and/or, according to the battery power of the mobile terminal The battery level determines the initial value and/or increase of x, for example, when the battery level is relatively full, x can be set to a value of 1 on the first scan and incremented at intervals of 1, while when the battery level is low, you can set x has a value of 2 on the first scan and increments at intervals of 2, etc.

In addition, when the WIFI function is activated, the first scan for WIFI access points can be performed. At this time, x in the above formula can be incremented from the value at the time of the first scan. For some other situations, such as when the mobile terminal is connected to the charger, successfully connected to the access point, or disconnected from the access point, it can also be considered that the WIFI access point has been scanned for the first time, that is, the WIFI access point can be scanned for the first time in these cases. The value of x is reset, then x in the above formula can also be incremented from the value at the first scan at this time. In this way, the WIFI access point can be scanned as soon as possible when the user needs it, so as to ensure the use effect of the WIFI function.

In addition, considering that when the above time interval increases exponentially, it is possible to increase the time interval to a very large value, so that scanning will not be performed for a very long time, which may affect the user's use of the WIFI function Therefore, as a preferred implementation manner, a time threshold may also be preset, and when the above-mentioned determined time interval is greater than the time threshold, the time threshold is used as the time interval. For example, the time threshold is set to 300 seconds, and if the above-mentioned determined time interval exceeds 300 seconds, the next scan of the WIFI access point is only performed according to the time interval of 300 seconds.

Corresponding to the above method, this embodiment also provides a device for scanning WIFI access points, which is used to implement the above embodiments and preferred implementation modes, and those that have already been described will not be repeated. As used below, the term "module" may be a combination of software and/or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

FIG. 3 is a structural block diagram of a device for scanning WIFI access points according to an embodiment of the present invention. As shown in FIG. 3 , the device includes: a determination module 32 and a scanning module 34 , and each module will be described in detail below.

The determining module 32 is used to determine the time interval for scanning the WIFI access point according to the state of the mobile terminal; the scanning module 34 is connected to the determining module 32 for scanning the WIFI access point according to the time interval determined by the determining module 32.

In this embodiment, through the above modules, the determination module 32 determines the time interval for scanning WIFI access points according to the state of the mobile terminal, and the scanning module 34 scans according to the time interval, so that the scanning WIFI access can be performed along with the state of the mobile terminal. The time interval of the point is changed, so that the time interval of scanning can be automatically adjusted, which solves the problem caused by the mobile terminal WIFI access point scanning according to a fixed time interval in the related technology, so as not to affect the use of WIFI functions and reduce the number of WIFI access points. The scanning frequency provides the possibility, which can reduce the battery power consumption of the mobile terminal by the WIFI function, prolong the standby time of the mobile terminal, and improve the user experience.
