Alleged module refers to a kind of series of computation machine programmed instruction section that can complete specific function, is more suitable for than computer program
In implementation procedure of the description software in the mobile terminal 100.Below by just above-mentioned each functional module 401-404 specific work(
It can be described in detail.Wherein：
The WLAN open detections module 401, for detecting whether mobile terminal currently opens WLAN functions.The present invention
In, after the WLAN WifiTrak method is opened, whether can currently open WLAN functions by detection mobile terminal in real time, herein
WLAN functions are to search for the function of periphery WLAN.Fig. 7 is refer to, Fig. 7 is real to open mobile terminal one after WLAN functions
The user interface schematic diagram of example is applied, as can be seen from Figure 7, after WLAN functions are opened, mobile terminal can search for the wireless local on periphery
Network, and all WLANs searched are shown on mobile terminals in a manner of available WLAN lists.Need
Bright, in the prior art, after WLAN functions are opened, mobile terminal can continue the WLAN around search, continue
Search refers to that mobile terminal is periodically searched for larger frequency (less cycle), between the time between now searching for twice
It can be ignored every approximation, mobile terminal power consumption is larger when persistently searching for.
The speed acquiring module 402, for after the unlatching of WLAN functions, obtaining the translational speed of the mobile terminal.
In the present embodiment, when obtaining the translational speed of mobile terminal, specific method comprises the following steps：(1) according to prefixed time interval
Periodically obtain the positional information of the mobile terminal；(2) calculated according to the positional information and the prefixed time interval
The translational speed of the mobile terminal.Specifically, being provided with GPS module in mobile terminal, movement can be obtained by GPS module
The positional information of terminal, when calculating the translational speed of mobile terminal, the position of mobile terminal is obtained according to prefixed time interval
Information, during such as the prefixed time interval T=0.5 seconds, then obtained a positional information, obtained multiple positional informations every 0.5 second
D1, D2, D3 ... ... Dn are designated as, then corresponding translational speed is the distance between two neighboring positional information between preset time
Every T ratio.In the present invention, due to obtaining the positional information of mobile terminal every prefixed time interval T and calculating translational speed,
Therefore mobile terminal can get a translational speed every prefixed time interval.
The judge module 403, for judging whether the translational speed is more than pre-set velocity threshold value.In the present embodiment,
A translational speed can be got every prefixed time interval T, the translational speed got at current time is more than default speed
When spending threshold value, show that current mobile terminal is in mobile unstable state, user is likely to be at the state of hurrying up, used in such cases
The probability that mobile phone is played in family online is smaller, therefore now reduces the search rate of WLAN；Conversely, if translational speed is less than in advance
If threshold speed, then illustrating that mobile terminal is in a metastable state, the probability that mobile phone is played in now user's online is larger, because
This now heightens the search rate of WLAN.Further, since a mobile speed can be got every prefixed time interval T
Degree, and judge that the state of mobile terminal largely has error by a translational speed, it is impossible to accurately reflect movement
The state of terminal, therefore can determine the need for adjusting the search rate of WLAN by multiple judged result.Tool
Body, it is described to judge that the step of whether translational speed is more than pre-set velocity threshold value is specially in other preferred embodiments：
(1) judge whether the translational speed is persistently more than pre-set velocity threshold value in preset duration；(2) if the determination result is YES, then
Judge that the translational speed is more than the pre-set velocity threshold value, if judged result is no, judge the translational speed be less than or
Equal to the pre-set velocity threshold value.By judging whether the translational speed of mobile terminal in preset duration is persistently more than pre-set velocity
Threshold value, it is to play pendulum or metastable state that can more accurately judge current mobile terminal.In the present embodiment,
The preset duration is pre-set by application developer or user, and its value is more than prefixed time interval.
The search rate control module 404, for when the translational speed is more than the pre-set velocity threshold value, turning down
The search rate of WLAN, and when the translational speed is less than or equal to the pre-set velocity threshold value, heighten wireless
The search rate of LAN.That is, when the translational speed of mobile terminal is more than pre-set velocity threshold value, searching for WLAN is turned down
Rope frequency, when the translational speed of mobile terminal is less than or equal to pre-set velocity threshold value, heighten the search rate of WLAN.
It should be noted that after WLAN functions are opened, mobile terminal can carry out the search of WLAN with initial search frequency f0, should
Initial search frequency pre-sets and stored.In addition, when turning down the search rate of WLAN, can be by search rate
Turned down according to default unit value, such as turn down a unit value every time；It is, of course, also possible to the search frequency by WLAN
Rate is directly turned down to default lowest frequency value.It should be noted that when turning down the frequency of WLAN, can set one it is minimum
Frequency values, when search rate reaches the lowest frequency value, even if the translational speed of current mobile terminal is more than pre-set velocity threshold
Value, does not continue to turn down search rate yet.Similarly, when heightening the search rate of WLAN, can by search rate according to
Default unit value is heightened, and such as heightens a unit value every time；It is it is, of course, also possible to the search rate of WLAN is straight
Connect and heighten to default highest frequency value.It should be noted that when turning down the frequency of WLAN, a highest frequency can be set
Value, when search rate reaches the highest frequency value, even if the translational speed of current mobile terminal is less than pre-set velocity threshold value,
Do not continue to heighten search rate.
By above-mentioned module 401 to 404, WLAN WifiTrak program of the present invention, after mobile unlatching WLAN functions, obtain
The translational speed of the mobile terminal simultaneously judges whether the translational speed is more than pre-set velocity threshold value, and in the translational speed
The search rate of WLAN is turned down during more than the pre-set velocity threshold value, and is less than or equal to institute in the translational speed

The search of WLAN is carried out, when the translational speed for detecting mobile terminal is more than pre-set velocity threshold value, is turned down current
Search rate.In addition, when turning down the search rate of WLAN, search rate can be adjusted according to default unit value
It is low, such as a unit value is turned down every time；It is, of course, also possible to the search rate of WLAN is directly turned down to default lowest frequency
Rate value.It should be noted that when turning down the frequency of WLAN, a lowest frequency value can be set, when search rate reaches
During the lowest frequency value, even if the translational speed of current mobile terminal is more than pre-set velocity threshold value, do not continue to turn down search yet
Frequency.
Step S505, heighten the search rate of WLAN.That is, when the translational speed of mobile terminal is less than or equal in advance
If during threshold speed, heighten the search rate of WLAN.Similarly, when heightening the search rate of WLAN, can incite somebody to action
Search rate is heightened according to default unit value, such as heightens a unit value every time；It is, of course, also possible to by WLAN
Search rate directly heighten to default highest frequency value.It should be noted that when turning down the frequency of WLAN, can set
One highest frequency value, when search rate reaches the highest frequency value, even if the translational speed of current mobile terminal is less than in advance
If threshold speed, do not continue to heighten search rate yet.
