Embodiment one
Fig. 1 is a kind of schematic flow sheet of WiFi localization methods that the embodiment of the present invention one is provided.The method can be by
WiFi positioners are performed, and the device can be realized by software and/or hardware, typically can it is integrated in the terminal.Such as Fig. 1 institutes
Show, the method specifically may include steps of：
If the Wi-Fi hotspot sum of step 101, historical position reaches the first predetermined threshold value, according to standard channel order according to
The Wi-Fi hotspot of secondary each WiFi channels of scanning.
Typically, channel is also referred to as passage or frequency range, refers to the data-signal transmission using wireless signal as transport vehicle
Passage, wireless network can run over multiple channels.Wirelessly shared network is generally termed Wi-Fi hotspot, typically makes
With wireless router as Wi-Fi hotspot.Current WiFi network equipment typically all supports 13 WiFi channels, i.e. mobile terminal
During Wi-Fi hotspot in scanning circumstance, the Wi-Fi hotspot generally in 13 WiFi channels of scanning, this 13 WiFi channels are remembered successively
Make 1~13 channel, each WiFi channel has incomplete same frequency range, for example, the centre frequency of 1 channel is
2412MHz, its frequency range is 2401~2423MHz, and the centre frequency of 2 channels is 2417MHz, frequency range is 2046~
2428MHz.When dispatching from the factory, default channel is traditionally arranged to be what 1,6 and 11 these three channels, i.e. router sent to usual router
Wireless network signal is generally mainly distributed on three channels, and during using Wi-Fi hotspot in mobile scanning terminal environment, this three
Wi-Fi hotspot number in individual channel is generally more, and the position in standard channel order is more forward.
Exemplary, historical position refers to the position positioned in the historical juncture.First predetermined threshold value could be arranged to
More than the minimum value that can realize carrying out mobile terminal pinpoint Wi-Fi hotspot number, or corresponding threshold value model
Enclose, for example, at least scanning obtains 10 Wi-Fi hotspot information more accurate positioning can be carried out to mobile terminal, then first
Predetermined threshold value could be arranged to the numerical value more than 10.Standard channel order refers to according in 13 WiFi channels in historical position
The Wi-Fi hotspot number of each WiFi channel, the channel order obtained after being ranked up to each WiFi channels.Specifically, WiFi
The Wi-Fi hotspot number of channel is more, then the WiFi channels are more forward in the position of standard channel order, more early scanning WiFi
Channel.
Specifically, historical position can be position when being positioned to mobile terminal the last time, for example, user is 8:00
Shi Jinhang is positioned for the first time, 8:Second positioning is carried out when 02, then 8:The Wi-Fi hotspot obtained when being positioned when 00 is total
Number is the Wi-Fi hotspot sum of historical position.It is understood that user is when consecutive tracking request is carried out, its moving range
It is typically small, and each passage focus number is held essentially constant in close position range, thus using being obtained at historical position
Standard channel order is scanned to WiFi channels and still is able to comparatively fast obtain more Wi-Fi hotspot information.Also, due to 1,6 and
Wi-Fi hotspot in 11 these three channels is generally more, and these three channels come first three position of standard channel order substantially,
WiFi channels are scanned using standard channel order thus can comparatively fast obtain the Wi-Fi hotspot number of predetermined number.
Exemplary, at historical position, mobile terminal can scan 13 WiFi channels, obtain each WiFi channel
Wi-Fi hotspot number, each WiFi channels are ranked up from more to few order according to Wi-Fi hotspot number, obtain standard
Channel order, and the Wi-Fi hotspot of all channels in log history position is total, if historical position Wi-Fi hotspot sum reaches first
During predetermined threshold value, then in current position, mobile terminal scans each WiFi channels successively according to standard channel order.
It should be noted that standard channel can also in the terminal be pre-set sequentially, it is preferred that by 1,6 and 11
These three WiFi channels are set to first three position of standard channel order.
Step 102, when the number of Wi-Fi hotspot that scanning is obtained is more than the second predetermined threshold value, obtained according to scanning
Wi-Fi hotspot information determines the current location of user.
Exemplary, the WiFi heat that mobile terminal scans each WiFi channels and will scan successively according to standard channel order
Point number carries out accumulative summation, when the Wi-Fi hotspot number for scanning is more than the second predetermined threshold value, is then obtained according to scanning
The MAC Address of Wi-Fi hotspot information determines the current location of user.
Specifically, generally scanning the Wi-Fi hotspot number for obtaining reaches 10 or so, it is more accurate with regard to can carry out
Positioning.Second predetermined threshold value can be set to 10, each WiFi channels are scanned successively according to standard channel number sequence, it is assumed that scanning
During complete two WiFi channels, the accumulative number of the Wi-Fi hotspot for obtaining has reached 10, then 10 WiFi for being obtained according to scanning
Hot information is positioned to user.It is understood that in scanning process, can be with the WiFi heat in scanning to scanning
The number of point is added up, and when the Wi-Fi hotspot number being accumulated by reaches the second predetermined threshold value, then basis is currently swept immediately
Retouch to all of Wi-Fi hotspot information user is positioned.
The technical scheme that the present embodiment is provided, if the Wi-Fi hotspot sum of historical position reaches the first predetermined threshold value, root
Scan the Wi-Fi hotspot of each WiFi channels successively according to standard channel order；When the number for scanning the Wi-Fi hotspot for obtaining is more than second
During predetermined threshold value, the Wi-Fi hotspot information obtained according to scanning determines the current location of user.Prior art uses mobile terminal
During scanning Wi-Fi hotspot, scanning every time, ((Micro Controller Unit, MCU) is all needed the control unit in mobile terminal
To be communicated with WiFi chip by way of order, scanning through 13 passages then needs 13 subcommands to interact, and positions elapsed time
It is long, influence the real-time of positioning, poor user experience.The embodiment of the present invention is by using above-mentioned technical proposal so that scanning to one
Can be positioned after the Wi-Fi hotspot of fixed number amount, 13 WiFi channels all be scanned through relative to prior art is determined again

Property all WiFi channels of scanning, obtain the Wi-Fi hotspot information of all WiFi channels；According to the Wi-Fi hotspot of all WiFi channels
Information determines the current location of user.
It is exemplary, when the Wi-Fi hotspot sum of historical position is less than the first predetermined threshold value, then one-off scanning 13
WiFi channels, obtain all of Wi-Fi hotspot information in 13 WiFi channels.One-off scanning refer to MCU in mobile terminal to
WiFi chip sends the order of the complete 13 WiFi channels of one-off scanning, i.e. MCU is only once communicated with WiFi chip, orders
WiFi chip scans 13 WiFi channels, after WiFi chip scans through 13 WiFi channels, disposably returns to the institute scanned
There is Wi-Fi hotspot information.Because the Wi-Fi hotspot quantity that scanning is obtained reaches certain amount (such as 10), can be according to scanning
The Wi-Fi hotspot information for obtaining accurately is positioned to mobile terminal.If the first predetermined threshold value is set to 10, and historical position
Locate the total number of Wi-Fi hotspot in all WiFi channels less than 10, then had to scan through 13 WiFi channels, owned
The Wi-Fi hotspot information of WiFi channels, can ensure accurately to position mobile terminal to greatest extent.Due to successively
13 WiFi channels of scanning then need the MCU of mobile terminal and WiFi chip to carry out 13 subcommands to interact, and disposable whole is swept
The mode retouched, it is only necessary to 1 mentioned order interaction, thus in the scene that all WiFi channels must all have been swept, it is disposable complete
Time needed for having swept is shorter, and locating speed is faster.
