Based on the hardware structure of the mobile terminal 100 and the communication network system, various embodiments of the method of the present invention are provided.

First, the present invention provides a mobile terminal including a memory, a processor, and a WLAN hotspot searching program 400 stored in the memory and operable on the processor.

Fig. 3 is a functional block diagram of a WLAN hotspot searching procedure 400 according to a first embodiment of the present invention. In this embodiment, the WLAN hotspot searching program 400 can be divided into one or more modules, which are stored in the memory 109 of the mobile terminal 100 and executed by one or more processors (in this embodiment, the controller 110) to complete the present invention. For example, in fig. 3, the WLAN hotspot searching process 400 can be divided into a WLAN on detection module 401, a speed acquisition module 402, a determination module 403, and a search frequency control module 404. The module referred to in the present invention refers to a series of computer program instruction segments capable of performing specific functions, and is more suitable than a computer program for describing the execution process of software in the mobile terminal 100. The detailed description of the functions of the

functional modules

401 and 404 will be described below. Wherein:

the WLAN activation detecting module 401 is configured to detect whether the mobile terminal activates a WLAN function currently. In the invention, after the WLAN hotspot searching method is started, whether the mobile terminal currently starts a WLAN function or not is detected in real time, wherein the WLAN function is a function of searching peripheral wireless local area networks. Referring to fig. 7, fig. 7 is a schematic view of a user interface of an embodiment of a mobile terminal after a WLAN function is turned on, and as can be seen from fig. 7, after the WLAN function is turned on, the mobile terminal searches for peripheral wireless local area networks and displays all the searched wireless local area networks on the mobile terminal in a form of an available WLAN list. It should be noted that, in the prior art, after the WLAN function is turned on, the mobile terminal may continuously search for the surrounding wireless local area network, where the continuous search refers to periodic search at a relatively high frequency (relatively small period), a time interval between two searches may be approximately ignored, and power consumption of the mobile terminal is relatively high when the mobile terminal continuously searches.

The speed obtaining module 402 is configured to obtain a moving speed of the mobile terminal after the WLAN function is turned on. In this embodiment, when the moving speed of the mobile terminal is obtained, the specific method includes the following steps: (1) periodically acquiring the position information of the mobile terminal according to a preset time interval; (2) and calculating the moving speed of the mobile terminal according to the position information and the preset time interval. Specifically, a GPS module is arranged in the mobile terminal, the position information of the mobile terminal can be obtained through the GPS module, when the moving speed of the mobile terminal is calculated, the position information of the mobile terminal is obtained according to a preset time interval, if the preset time interval T is 0.5 seconds, the position information is obtained every 0.5 seconds, the obtained plurality of position information are recorded as D1, D2, D3, and … … Dn, and the corresponding moving speed is the ratio of the distance between two adjacent position information to the preset time interval T. In the invention, the position information of the mobile terminal is obtained at intervals of the preset time interval T and the moving speed is calculated, so that the mobile terminal can obtain a moving speed at intervals of the preset time interval.

The determining module 403 is configured to determine whether the moving speed is greater than a preset speed threshold. In this embodiment, a moving speed may be obtained at intervals of a preset time interval T, and when the moving speed obtained at the present time is greater than a preset speed threshold, it indicates that the present mobile terminal is in an unstable moving state, and the user may be in a fast-walking state, in which case the probability that the user surfs the internet and plays a mobile phone is small, so that the search frequency of the wireless local area network is reduced at this time; on the contrary, if the moving speed is smaller than the preset speed threshold, the mobile terminal is in a relatively stable state, and the probability that the user surfs the internet and plays the mobile phone is higher, so that the searching frequency of the wireless local area network is increased. In addition, since a moving speed can be obtained at intervals of a preset time interval T, and the state of the mobile terminal is judged by one moving speed, which has errors to a great extent and cannot accurately reflect the state of the mobile terminal, whether the search frequency of the wireless local area network needs to be adjusted can be determined by multiple judgment results. Specifically, in other preferred embodiments, the step of determining whether the moving speed is greater than a preset speed threshold specifically includes: (1) judging whether the moving speed is continuously greater than a preset speed threshold value within a preset time length; (2) if the judgment result is yes, the moving speed is judged to be larger than the preset speed threshold, and if the judgment result is no, the moving speed is judged to be smaller than or equal to the preset speed threshold. By judging whether the moving speed of the mobile terminal in the preset time duration is continuously greater than the preset speed threshold value, whether the current mobile terminal is in an unstable state or a relatively stable state can be judged more accurately. In this embodiment, the preset duration is preset by a program developer or a user, and a value of the preset duration is greater than a preset time interval.

The search frequency control module 404 is configured to decrease the search frequency of the wireless local area network when the moving speed is greater than the preset speed threshold, and increase the search frequency of the wireless local area network when the moving speed is less than or equal to the preset speed threshold. That is, when the moving speed of the mobile terminal is greater than the preset speed threshold, the search frequency of the wireless local area network is reduced, and when the moving speed of the mobile terminal is less than or equal to the preset speed threshold, the search frequency of the wireless local area network is increased. It should be noted that, after the WLAN function is turned on, the mobile terminal searches for the wireless local area network at an initial search frequency f0, which is preset and stored. In addition, when the search frequency of the wireless local area network is reduced, the search frequency can be reduced according to a preset unit value, for example, the search frequency is reduced by one unit value every time; of course, the search frequency of the wireless lan can also be directly adjusted down to the preset minimum frequency value. It should be noted that, when the frequency of the wireless local area network is turned down, a lowest frequency value is set, and when the search frequency reaches the lowest frequency value, even if the moving speed of the current mobile terminal is greater than the preset speed threshold, the search frequency is not turned down any more. Similarly, when the search frequency of the wireless local area network is increased, the search frequency can be increased according to a preset unit value, for example, the search frequency is increased by one unit value every time; of course, the search frequency of the wireless lan can also be directly increased to the preset highest frequency value. It should be noted that, when the frequency of the wireless local area network is turned down, a highest frequency value is set, and when the search frequency reaches the highest frequency value, even if the moving speed of the current mobile terminal is less than the preset speed threshold, the search frequency is not continuously turned up.

Through the modules 401 to 404, the WLAN hotspot searching program of the present invention, after the WLAN function is started, obtains the moving speed of the mobile terminal and determines whether the moving speed is greater than a preset speed threshold, decreases the search frequency of the wireless local area network when the moving speed is greater than the preset speed threshold, and increases the search frequency of the wireless local area network when the moving speed is less than or equal to the preset speed threshold, thereby achieving determining whether the mobile terminal is in a relatively stable state by the moving speed of the mobile terminal, increasing the search frequency of the wireless local area network when the mobile terminal is stable, and decreasing the search frequency of the wireless local area network when the mobile terminal is unstable, thereby avoiding wasting unnecessary electric quantity when the mobile terminal continuously searches the wireless local area network with a higher search frequency, and reducing the power consumption of the mobile terminal.

Further, based on the above-mentioned first embodiment of the WLAN hotspot searching program 400 of the present invention, a second embodiment of the WLAN hotspot searching program 400 of the present invention is proposed. Referring to fig. 4, fig. 4 is a functional module diagram of a WLAN hotspot searching program 400 according to a second embodiment of the present invention, wherein compared with the first embodiment, the WLAN hotspot searching program 400 further includes an acceleration determining module 405 and a screen state detecting module 406.

The acceleration determination module 405 is configured to, when the moving speed is greater than the preset speed threshold, obtain a horizontal acceleration of the mobile terminal and determine whether the horizontal acceleration is less than a preset acceleration, if the horizontal acceleration is less than the preset acceleration, call the search frequency control module 404 to increase the search frequency of the wireless local area network, otherwise, if the horizontal acceleration is greater than or equal to the preset acceleration, call the search frequency control module 404 to decrease the search frequency of the wireless local area network. In this embodiment, when the moving speed of the mobile terminal is greater than the preset speed threshold, the search frequency of the wireless local area network is not directly reduced, but whether the horizontal acceleration of the mobile terminal is smaller than the preset acceleration is further determined, if the horizontal acceleration of the mobile terminal is smaller than the preset acceleration, the user is currently in steady movement, and at this time, the probability that the user surfs the internet and plays the mobile phone is also high, so the search frequency of the wireless local area network is increased, and if the horizontal acceleration of the mobile terminal is greater than or equal to the preset acceleration, the user is in unstable movement at this time, and at this time, the probability that the user surfs the internet and plays the mobile phone is very low, so the search frequency of the wireless local area network is reduced at this. The moving state of the mobile terminal is judged through the two parameters of the moving speed and the horizontal acceleration of the mobile terminal, the accuracy is higher, and the mobile terminal is more suitable for actual conditions.

The screen state detecting module 406 is configured to detect a screen state of the mobile terminal after the WLAN function is turned on, and call the speed obtaining module 402 when the screen state of the mobile terminal is a bright screen. In the invention, the screen state of the mobile terminal comprises a bright screen and a black screen; specifically, when detecting the bright screen of the mobile terminal, the method comprises the following steps: registering a bright screen monitoring broadcast with an operating system of the mobile terminal in advance, sending the bright screen broadcast by the operating system when the mobile terminal is bright, and judging that the screen state of the mobile terminal is bright when the bright screen broadcast is received. Similarly, when detecting the black screen of the mobile terminal, the method comprises the following steps: registering a black screen monitoring broadcast with an operating system of the mobile terminal in advance, sending the black screen broadcast by the operating system when the mobile terminal is in a black screen state, and judging that the screen state of the mobile terminal is in the black screen state when the black screen broadcast is received. The speed obtaining module 402 is called only when the screen is in a bright screen state, because when the mobile terminal is in a bright screen state, the probability that the user operates the mobile terminal (for example, surf the internet to play games) is high, and the probability that the user needs to surf the internet is low in a black screen state.

401 and 406, after the WLAN hotspot searching program of the present invention starts the WLAN function, the searching frequency of the wireless local area network is adjusted according to three parameters of the screen state, the moving speed and the horizontal acceleration of the mobile terminal, when the screen state is bright screen and the moving speed is less than or equal to the preset speed threshold, or the moving speed is greater than the preset speed threshold but the horizontal acceleration is less than the preset acceleration, the searching frequency of the wireless local area network is increased, and when the screen state is bright screen and the moving speed is greater than or equal to the preset speed threshold, or the screen state is black screen, the searching frequency of the wireless local area network is decreased.

In addition, the present invention provides a WLAN hotspot searching method, which is applied to the mobile terminal shown in fig. 1 to 2. Fig. 5 is a flowchart illustrating a WLAN hotspot searching method according to a first embodiment of the present invention. In this embodiment, the execution order of the steps in the flowchart shown in fig. 5 may be changed and some steps may be omitted according to different requirements. The WLAN hotspot searching method comprises the following steps:

step S501, detecting whether the mobile terminal currently starts a WLAN function.

In the invention, after the WLAN hotspot searching method is started, whether the mobile terminal currently starts a WLAN function or not is detected in real time, wherein the WLAN function is a function of searching peripheral wireless local area networks. Referring to fig. 7, fig. 7 is a schematic view of a user interface of an embodiment of a mobile terminal after a WLAN function is turned on, and as can be seen from fig. 7, after the WLAN function is turned on, the mobile terminal searches for peripheral wireless local area networks and displays all the searched wireless local area networks on the mobile terminal in a form of an available WLAN list. It should be noted that, in the prior art, after the WLAN function is turned on, the mobile terminal may continuously search for the surrounding wireless local area network, where the continuous search refers to periodic search at a relatively high frequency (relatively small period), a time interval between two searches may be approximately ignored, and power consumption of the mobile terminal is relatively high when the mobile terminal continuously searches.

Step S502, if the WLAN function is started, the moving speed of the mobile terminal is obtained. Meanwhile, if the WLAN function is not turned on, the step S501 is repeatedly executed.

In this embodiment, when the moving speed of the mobile terminal is obtained, the specific method includes the following steps: (1) periodically acquiring the position information of the mobile terminal according to a preset time interval; (2) and calculating the moving speed of the mobile terminal according to the position information and the preset time interval. Specifically, a GPS module is arranged in the mobile terminal, the position information of the mobile terminal can be obtained through the GPS module, when the moving speed of the mobile terminal is calculated, the position information of the mobile terminal is obtained according to a preset time interval, if the preset time interval T is 0.5 seconds, the position information is obtained every 0.5 seconds, the obtained plurality of position information are recorded as D1, D2, D3, and … … Dn, and the corresponding moving speed is the ratio of the distance between two adjacent position information to the preset time interval T. In the invention, the position information of the mobile terminal is obtained at intervals of the preset time interval T and the moving speed is calculated, so that the mobile terminal can obtain a moving speed at intervals of the preset time interval.

Step S503 is to determine whether the moving speed is greater than a preset speed threshold, if so, step S504 is executed, otherwise, if not, step S505 is executed.

In this embodiment, a moving speed may be obtained at intervals of a preset time interval T, and when the moving speed obtained at the present time is greater than a preset speed threshold, it indicates that the present mobile terminal is in an unstable moving state, and the user may be in a fast-walking state, and in this case, the probability that the user surfs the internet and plays a mobile phone is small, so step S504 is executed at this time to reduce the search frequency of the wireless local area network; on the contrary, if the moving speed is smaller than the preset speed threshold, it indicates that the mobile terminal is in a relatively stable state, and the probability that the user surfs the internet and plays the mobile phone is higher, so step S505 is executed to properly increase the search frequency of the wireless local area network.

In addition, since a moving speed can be obtained at intervals of a preset time interval T, and the state of the mobile terminal is judged by one moving speed, which has errors to a great extent and cannot accurately reflect the state of the mobile terminal, whether the search frequency of the wireless local area network needs to be adjusted can be determined by multiple judgment results. Specifically, in other preferred embodiments, the step of determining whether the moving speed is greater than a preset speed threshold specifically includes: (1) judging whether the moving speed is continuously greater than a preset speed threshold value within a preset time length; (2) if the judgment result is yes, the moving speed is judged to be larger than the preset speed threshold, and if the judgment result is no, the moving speed is judged to be smaller than or equal to the preset speed threshold. By judging whether the moving speed of the mobile terminal in the preset time duration is continuously greater than the preset speed threshold value, whether the current mobile terminal is in an unstable state or a relatively stable state can be judged more accurately. In this embodiment, the preset duration is preset by a program developer or a user, and a value of the preset duration is greater than a preset time interval.

Step S504, the search frequency of the wireless local area network is reduced. Namely: and when the moving speed of the mobile terminal is greater than a preset speed threshold, reducing the search frequency of the wireless local area network. After the WLAN function is turned on, the mobile terminal searches for a wireless local area network at an initial search frequency f0, and when it is detected that the moving speed of the mobile terminal is greater than a preset speed threshold, the current search frequency is reduced. In addition, when the search frequency of the wireless local area network is reduced, the search frequency can be reduced according to a preset unit value, for example, the search frequency is reduced by one unit value every time; of course, the search frequency of the wireless lan can also be directly adjusted down to the preset minimum frequency value. It should be noted that, when the frequency of the wireless local area network is turned down, a lowest frequency value is set, and when the search frequency reaches the lowest frequency value, even if the moving speed of the current mobile terminal is greater than the preset speed threshold, the search frequency is not turned down any more.

Step S505, the search frequency of the wireless lan is increased. That is, when the moving speed of the mobile terminal is less than or equal to the preset speed threshold, the search frequency of the wireless local area network is increased. Similarly, when the search frequency of the wireless local area network is increased, the search frequency can be increased according to a preset unit value, for example, the search frequency is increased by one unit value every time; of course, the search frequency of the wireless lan can also be directly increased to the preset highest frequency value. It should be noted that, when the frequency of the wireless local area network is turned down, a highest frequency value is set, and when the search frequency reaches the highest frequency value, even if the moving speed of the current mobile terminal is less than the preset speed threshold, the search frequency is not continuously turned up.

Through the steps S501 to S505, after the WLAN function is started, the WLAN hotspot searching method of the present invention obtains the moving speed of the mobile terminal and determines whether the moving speed is greater than the preset speed threshold, decreases the search frequency of the wireless local area network when the moving speed is greater than the preset speed threshold, and increases the search frequency of the wireless local area network when the moving speed is less than or equal to the preset speed threshold, thereby determining whether the mobile terminal is in a relatively stable state according to the moving speed of the mobile terminal, increasing the search frequency of the wireless local area network when the mobile terminal is stable, and decreasing the search frequency of the wireless local area network when the mobile terminal is unstable, thereby avoiding wasting unnecessary electric quantity when the mobile terminal continuously searches the wireless local area network with a higher search frequency, and reducing the power consumption of the mobile terminal.

Further, based on the first embodiment, a second embodiment of the WLAN hotspot searching method of the present invention is provided. Fig. 6 is a flowchart illustrating an implementation of a WLAN hotspot searching method according to a second embodiment of the present invention. In this embodiment, the execution order of the steps in the flowchart shown in fig. 6 may be changed and some steps may be omitted according to different requirements. The WLAN hotspot searching method comprises the following steps:

step S601, detecting whether the mobile terminal currently starts the WLAN function, if the mobile terminal starts the WLAN function, step S602 is executed, otherwise, repeatedly detecting whether the WLAN function is started.

Step S602, detecting a screen state of the mobile terminal, if the screen state of the mobile terminal is bright, performing step S603, otherwise, if the screen state of the mobile terminal is black, performing step S606.

In the invention, the screen state of the mobile terminal comprises a bright screen and a black screen; specifically, when detecting the bright screen of the mobile terminal, the method comprises the following steps: registering a bright screen monitoring broadcast with an operating system of the mobile terminal in advance, sending the bright screen broadcast by the operating system when the mobile terminal is bright, and judging that the screen state of the mobile terminal is bright when the bright screen broadcast is received. Similarly, when detecting the black screen of the mobile terminal, the method comprises the following steps: registering a black screen monitoring broadcast with an operating system of the mobile terminal in advance, sending the black screen broadcast by the operating system when the mobile terminal is in a black screen state, and judging that the screen state of the mobile terminal is in the black screen state when the black screen broadcast is received. When the screen is in the bright screen state, the step S603 is further executed because when the mobile terminal is in the bright screen state, the probability that the user operates the mobile terminal (for example, surf the internet to play games) is higher, and the probability that the user needs to surf the internet in the black screen state is lower.

Step S603, obtaining a moving speed of the mobile terminal.

Step S604, determining whether the moving speed is greater than a preset speed threshold, if so, performing step S605, otherwise, if not, performing step S607.

Step S605, acquiring a horizontal acceleration of the mobile terminal and determining whether the horizontal acceleration is smaller than a preset acceleration, if so, executing step S607, otherwise, executing step S606.

In this embodiment, when the moving speed of the mobile terminal is greater than the preset speed threshold, the search frequency of the wireless local area network is not directly reduced, but whether the horizontal acceleration of the mobile terminal is smaller than the preset acceleration is further determined, if the horizontal acceleration of the mobile terminal is smaller than the preset acceleration, the user is currently in steady movement, and at this time, the probability that the user surfs the internet and plays the mobile phone is also high, so the search frequency of the wireless local area network is increased, and if the horizontal acceleration of the mobile terminal is greater than or equal to the preset acceleration, the user is in unstable movement at this time, and at this time, the probability that the user surfs the internet and plays the mobile phone is very low, so the search frequency of the wireless local area network is reduced at this. The moving state of the mobile terminal is judged through the two parameters of the moving speed and the horizontal acceleration of the mobile terminal, the accuracy is higher, and the mobile terminal is more suitable for actual conditions.

Step S606, the search frequency of the wireless lan is reduced.

Step S607, the search frequency of the wireless lan is increased.

Through the steps S601 to S607, after the WLAN function is turned on, the WLAN hotspot searching method of the present invention adjusts the search frequency of the wireless lan according to the three parameters of the screen state, the moving speed, and the horizontal acceleration of the mobile terminal, and when the screen state is bright screen and the moving speed is less than or equal to the preset speed threshold, or the moving speed is greater than the preset speed threshold but the horizontal acceleration is less than the preset acceleration, increases the search frequency of the wireless lan, and when the screen state is bright screen and the moving speed is greater than or equal to the preset speed threshold, or the screen state is black screen, decreases the search frequency of the wireless lan.
